Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
According to a first aspect of the present application, there is provided a post-exit walking route guidance system for guiding a walking route of a driver from a vehicle to a target position (destination of travel) after alighting. FIG. 1 schematically shows a simplified block diagram of a walking route guidance system 100 according to an embodiment of the present application. FIG. 2 shows a schematic diagram of a vehicle 10 including a walking route guidance system 100 according to an embodiment of the present application.
As shown in fig. 1, the walking route guidance system 100 includes: an illumination unit 110, a driving unit 120, a judgment unit 130, a vehicle information acquisition unit 140, and a control unit 150. The above-described constituent units included in the walking route guidance system 100 can be provided in the form of individual components or unit modules, which will be described in detail below.
The illumination unit 110 is mounted on the body of the vehicle 10 for projecting illumination light. The lighting unit 110 may be an existing lighting device of the vehicle 10, such as a turn signal (mounted on a rear view mirror or fender), a courtesy light (mounted on a vehicle chassis), a headlamp, or the like. Alternatively, the illumination unit 110 may be configured as a separate additional illumination device, and may be disposed at a position on the vehicle body suitable for projecting illumination light, such as a door or a roof portion. Specifically, the lighting unit 110 is configured to project directionally adjustable illumination light to provide appropriate illumination light to direct an after-alighting occupant 200 (shown in fig. 4A-9) to walk from the vehicle 10 to the target location 300, depending on the relative orientation of the vehicle 10 and the target location 300 (shown in fig. 3). The variable projection direction of the illumination light may be provided by adjusting a light projection angle of the illumination unit 110. According to embodiments of the present application, adjusting the light projection angle is achieved by enabling the illumination unit 110 to rotate 360 degrees or rotate circumferentially in a plane in combination with a translational motion, for example.
The driving unit 120 is configured to drive the illumination unit 110 to rotate to provide illumination light in a desired projection direction. The driving unit 120 is operatively connected with the lighting unit 110 to drive the lighting unit 110. According to embodiments of the present application, the driving unit 120 may be directly connected to the lighting unit 110 or indirectly connected to the lighting unit 110 through an intermediate transmission mechanism. The intermediate gear may be a separate gear or part of the lighting unit 110. For example, the driving unit 120 may be configured as a stepping motor, such as a bidirectional stepping motor, connected to the mounting base of the lighting unit 110 via a mechanical transmission mechanism to drive the lighting unit 110 to move steadily and slowly.
The determination unit 130 is configured to determine whether the vehicle 10 is parked within a preset area around the target position 300. In general, the vehicle 10 stops near the target position 300 located in the vehicle navigation system (not shown) after reaching the destination, and does not stop at the coordinate position specified by the vehicle navigation system. Therefore, the walking route guidance system 100 according to the present application sets in advance an expected parking area within a certain range around the target position 300 in the determination unit 130, and if the vehicle 10 parks in this expected parking area, the determination unit 130 determines that the vehicle 10 has reached the destination and parked in place. According to the embodiment of the present application, it is determined that the vehicle 10 has been parked in the expected parking area as a condition for determining to perform the adjustment of the projection angle of the illumination unit 110, and the walking route guidance system 100 determines to adjust the projection angle of the illumination unit 110 after the determination unit 130 determines that the vehicle 10 is parked in place.
According to an embodiment of the present application, the determination unit 130 may be configured to determine whether the vehicle 10 is parked within a preset area around the target position 300 based on a predetermined condition. The predetermined conditions may include: the navigation system of the vehicle 10 confirms that the vehicle 10 has reached the target position 300 located in the navigation system; and the vehicle speed of the vehicle 10 is zero. When the determination unit 130 determines that the above-described predetermined condition is satisfied, it is determined that the vehicle 10 is parked within a preset area (expected parking area) around the target position 300. In this case, the walking route guidance system 100 according to the present application starts adjustment of the projection angle of the illumination unit 110 using the determination result from the determination unit 130 as a trigger signal for performing adjustment of the projection angle of the illumination unit 110. Additionally, the above-described predetermined condition may include that the shift position of the vehicle 10 is in the parking range (P range), and when this condition is satisfied, the determination unit 130 determines that the vehicle 10 is parked around the target position 300 and is not temporarily parked, that is, the occupant 200 is about to get off to the target position 300. The determination with this additional condition is more accurate.
The vehicle information acquisition unit 140 is configured to acquire the vehicle direction and the parking position after the vehicle 10 is parked. The vehicle information acquisition unit 140 may acquire necessary information from a navigation system of the vehicle 10 or from a drive recording system (not shown) of the vehicle 10. According to an embodiment of the present application, the walking route guidance system 100 will determine the projection angle of the lighting unit 110 to provide directional lighting based on the information on the vehicle direction and the parking position acquired by the vehicle information acquisition unit 140. The vehicle direction may be defined as the heading of the vehicle head or the heading of the longitudinal axis of the vehicle body after the vehicle 10 is parked, and the parking position may be defined as the coordinates of the actual parking position of the vehicle 10 recorded in the vehicle navigation system. According to the walking route guidance system 100 of the present application, the vehicle direction may be a measurement start direction a (reference direction) of the angle of the lighting unit 110, and the parking position may be used together with the target position 300 to determine the expected projection direction P of the lighting light, as shown in fig. 3. The configuration of the control unit 150 will be described more specifically below.
The control unit 150 is configured to control and perform projection angle adjustment of the illumination unit 110. Both the determination result of the determination unit 130 and the information acquired by the vehicle information acquisition unit 140 are transmitted to the control unit 150, so that the control unit 150 determines whether and how to control the driving unit 120 to adjust the projection angle of the illumination unit 110 (as shown in fig. 2) based thereon. Specifically, as shown in fig. 3, the lighting unit 110 to be adjusted has a target projection angle α and a current projection angle β, and the control unit 150 controls the driving unit 150 to adjust the lighting unit 110 from the current projection angle β to the target projection angle α.
According to the present application, the target projection angle α may be defined as the angle at which the lighting unit 110 is to be adjusted to project the desired directional illumination light. The current projection angle β may be defined as an initial installation angle of the lighting unit 110 or a projection angle of the previous lighting ray, the current projection angle β being the initial installation angle of the lighting unit 110 indicating that the lighting unit 110 is adjusted back to the initial installation position after projecting the directional lighting ray, and the current projection angle β being the previous projection angle of the lighting unit 110 indicating that the lighting unit 110 remains at the current angle after projecting the lighting ray and is not adjusted back to the initial installation position.
Fig. 3 shows a schematic diagram of measuring the projection angle of the lighting unit 110 according to an embodiment of the application. In the example shown in fig. 3, the direction line a indicates a measurement start direction of the projection angle of the illumination unit 110, which may be a direction of a longitudinal axis of the vehicle 10 (vehicle direction); the direction line P indicates an expected projection direction of the illumination light, and may be a direction of a line connecting the illumination unit 110, which is to project the illumination light, to the target position 300; the direction line B indicates an initial installation direction of the lighting unit 110 or an illumination direction of previous illumination. As shown in fig. 3, the target projection angle α and the current projection angle β are both measured from a measurement start direction a, an angle between the measurement start direction a and the expected projection direction P represents the target projection angle α of the lighting unit 110, and an angle between the measurement start direction a and an initial installation direction or a previous illumination direction B of the lighting unit 110 represents the current projection angle β of the lighting unit 110.
Alternatively, the current projection angle β may be zero. In this case, the initial installation direction of the illumination unit 110 coincides or does not coincide with the longitudinal axis direction of the vehicle 10 (with the direction line a in fig. 3).
The target projection angle α is determined by the control unit 150 based on the coordinates of the target position 300 recorded in the navigation system of the vehicle 10 and the information of the vehicle direction and the parking position transmitted from the vehicle information acquisition unit 140. After the target projection angle α of the lighting unit 110 is determined, the control unit 150 generates a lighting unit adjustment signal with target projection angle information, and sends the lighting unit adjustment signal to the driving unit 120 in communication connection with the control unit 150, the driving unit 120 receives the lighting unit adjustment signal and then drives the lighting unit 110 to move from the current projection angle β to the target projection angle α, and after the target projection angle α is reached, the control unit 150 controls the lighting unit 110 to be turned on to project directional guiding light rays towards the target position 300 where the driver 200 will walk.
According to an embodiment of the present application, in case the lighting unit 110 is configured to change the projection angle in a rotational manner, the control unit 150 is configured to determine the angle that the lighting unit 110 needs to be rotated to adjust from the current projection angle β to the target projection angle α based on the current projection angle β and the target projection angle α of the lighting unit 110, the angle γ in fig. 3 indicating the required rotation angle. This angle γ that needs to be rotated may be included in the lighting unit adjustment signal provided to the driving unit 120. The driving unit 120 receives the lighting unit adjustment signal and then drives the lighting unit 110 to rotate by the rotation angle γ.
Preferably, according to an embodiment of the present application, the control unit 150 may be configured to turn off the lighting unit 110 after turning on the lighting unit 110 to project the illumination light for a predetermined period of time. The predetermined period of illumination may be, for example, 30s to 60 s. In general, the vehicle 10 will stop near the target position 300 after reaching the destination, the distance of the actual stop position from the target position 300 is small, and the time required for the occupant 200 to get out of the vehicle and then walk to the target position 300 is relatively small, and therefore, the time period for which the lighting unit 110 provides the guidance light may be set to be within 1 minute. Of course, this time period may be set as desired. This configuration of automatically turning off the lighting unit 110 makes it unnecessary for the occupant 200 to turn off the lighting unit 110 with a car key or the like after reaching the target position 300.
Preferably, in some embodiments, the appropriate number and location of lighting units 110 to provide the directing light may be selected based on the occupant's 200 seats within the vehicle 10, as will be described in more detail below.
According to an embodiment of the present application, a plurality of lighting units 110 may be disposed on the vehicle 10, for example, at different locations in the area of the body, doors, roof, rear view mirror or chassis of the vehicle 10. Thus, regardless of which seat within the vehicle 10 the occupant 200 is seated in or on which side of the vehicle 10 the occupant 200 will disembark, the walking route guidance system 100 is able to select the appropriate lighting unit 110 to provide the guidance light.
According to one embodiment, the vehicle 10 incorporating the walking route guidance system 100 of the present application is provided with four lighting units 110, and a seat detection unit (first detection unit, not shown) for detecting the seating position of the occupant 200 within the vehicle 10. The seat detection unit may be configured as a pressure sensor disposed in a seat within the vehicle 10, or as an onboard camera mounted inside the vehicle, whereby it is determined which seat within the vehicle 10 has the occupant 200 thereon through pressure detection or video detection. The seat detection unit is configured to be in communication with the control unit 150 to transmit the detection result to the control unit 150.
According to an embodiment of the present application, the control unit 150 is configured to first determine a target projection angle for each lighting unit 110, select an appropriate lighting unit 110 and selectively control the drive unit 120 corresponding to the selected lighting unit 110 to adjust the projection angle of the selected lighting unit 110 based on the seating position of the occupant 200 within the vehicle 10. The selection of the illumination unit 110 for different situations by the walking route guidance system 100 according to the present application will be described in detail below with reference to fig. 4A to 9.
For example, fig. 4A and 4B show a first situation where the vehicle 10 is parked and the occupant 200 is seated in the vehicle 10, with the occupant 200 seated in the front and rear left rows of the vehicle 10 and the right side of the vehicle 10 facing the target position 300.
In fig. 4A, the control unit 150 selects to adjust and activate the front and rear two lighting units 110 on the right side of the vehicle 10 to provide the directing light. This approach preferentially selects the lighting units 110 on the side closer to the target location 300 regardless of whether the selected lighting units 110 are near the occupant 200 in the vehicle 10. This configuration is suitable for a case where the light projected by the front and rear illumination units 110 on the left side may be blocked by the vehicle body, and selecting the illumination unit 110 closer to the target position 300 can prevent the light from being blocked by the vehicle body.
In fig. 4B, the control unit 150 selects the front and rear two illumination units 110 on the left side of the vehicle 10. This approach preferentially selects the lighting units 110 that are close to the occupant 200 regardless of whether the selected lighting units 110 are on the side closer to the target position 300 or may be obscured by the vehicle body. This configuration is suitable for situations where the lighting unit 110 is disposed in the roof area of the vehicle 10, where the directed light projected by the lighting unit 110 is substantially unobstructed by the vehicle body.
Fig. 5A and 5B show a second case of the vehicle 10 and the occupant 200, with the occupant 200 seated in the front left and rear right rows of the vehicle 10, while the right side of the vehicle 10 faces the target position 300.
In fig. 5A, the control unit 150 selects to adjust and activate two lighting units 110 in the front and rear rows on the right side of the vehicle. This way lighting units 110 closer to the target position 300 are preferentially selected. The occupant 200 seated in the driver seat can walk around from the front of the vehicle 10 after getting off and walk along the guide light projected from the lighting unit 110 in the front right row of the vehicle 10.
In fig. 5B, the control unit 150 selects the lighting units 110 of the front left and rear right rows of the vehicle 10. This approach preferentially selects the lighting units 110 that are closer to the occupant 200.
Fig. 6A and 6B show a third case of the vehicle 10 and the occupant 200, with the occupant 200 seated on both the left and right of the front seat of the vehicle 10, while the right side of the vehicle 10 faces the target position 300.
In fig. 6A, the control unit 150 selects to adjust and activate two lighting units 110 facing one side of the target position 300. This way lighting units 110 on the side closer to the target position 300 are preferentially selected. Specifically, the lighting unit 110 at the rear right of the vehicle 10 may serve as an optional auxiliary lighting unit for providing auxiliary lighting light, and the lighting unit 110 at the front right of the vehicle 10 may serve as a main lighting unit.

In fig. 7A, the control unit 150 selects to adjust and activate the lighting units 110 in the front and rear rows on the right side of the vehicle 10. This way lighting units 110 closer to the target position 300 are preferentially selected. The occupant 200 at the driving seat may walk along the guide light projected from the lighting unit 110 at the front right of the vehicle 10 after getting off the vehicle, and the occupant 200 at the left rear of the vehicle 10 may walk along the guide light projected from the lighting unit at the right rear of the vehicle 10 after getting off the vehicle after passing behind the vehicle 10.
In fig. 7B, the control unit 150 selects the driving position and the lighting unit 110 on the right rear row of the vehicle 10. This approach preferentially selects the lighting units 110 that are closer to the occupant 200. The control unit 150 does not select the lighting unit 110 in the rear left row of the vehicle 10 because the directing light projected by this lighting unit 110 will be between the light projected by the selected lighting unit 110, and there is no need to select this lighting unit 110 in view of the actual likely walking path.
Of course, in other embodiments, all three lighting units corresponding to the seating positions of the three occupants 200 may be activated.
Fig. 8A and 8B show a fifth case of the vehicle 10 and the occupant 200, in which the occupant 200 is seated on both the left and right sides of the front-rear row of the vehicle 10, and the right side of the vehicle 10 faces the target position 300.
In fig. 8A, the control unit 150 selects to adjust and activate the lighting units 110 in the front and rear rows on the right side of the vehicle 10. This way lighting units 110 closer to the target position 300 are preferentially selected. The front seated occupant 200 may walk behind the vehicle 10 passing in front of the vehicle 10 after getting off the vehicle and walk along the guide light projected by the right front row lighting unit 110 of the vehicle 10, and the rear seated occupant 200 may walk behind the vehicle 10 passing behind the vehicle 10 and walk along the guide light projected by the right rear row lighting unit 110 of the vehicle 10.
In FIG. 8B, the front and rear rows of lighting units 110 on the right side of the vehicle 10 may be selectively adjusted and activated. The lighting unit 110 in the front left row (driving position) of the vehicle 10 may additionally be selected, that is, the lighting unit 110 in the front left row (driving position) of the vehicle 10 may be used as an optional auxiliary lighting unit. The guiding light that can be projected by the lighting unit 110 of the driving seat is indicated by a dotted line in fig. 8B.
Of course, in other embodiments, all of the four lighting units corresponding to the seating positions of the four occupants 200 may be activated.
Considering that the projected guiding light may also be blocked by an object (large-sized object) in the illumination route, the walking route guiding system 100 according to the present application may include a blocking detection unit (second detection unit, not shown) for detecting whether the illumination light projected by the illumination unit 110 toward the target position 300 is blocked. The occlusion detection unit may be configured as an in-vehicle radar device in communicative connection with the control unit 150 for detecting whether the projected illumination light will be occluded by an object in the intended illumination path. Under the condition that it is confirmed that the illumination light to be projected may be blocked, the blocking detection unit sends the detection result to the control unit 150, the control unit 150 selects another illumination unit 110 whose illumination light is not blocked, and controls the corresponding driving unit 120 to adjust the selected illumination unit 110 to the target projection angle, and starts the illumination unit 110 to project the guiding light.
Figure 9 shows an alternative way of avoiding the obstruction. The driver 200 is seated on both the left and right sides of the front row of the vehicle 10, the right side of the vehicle 10 faces the target position 300, and an object 400 is present in the expected projected route of the lighting unit 110 on the right side of the front row of the vehicle 10 to the target position 300. In this case, the control unit 150 will preferentially select, based on the detection result of the blocking detection unit, the lighting unit 110 on the side facing the target position 300 and having the projected light not blocked by the object 400, that is, the lighting unit 110 on the right rear row of the vehicle 10, to be adjusted and activated. Meanwhile, in the case where the lighting units 110 are disposed at positions that avoid the projected illumination light from being blocked by the vehicle 10 itself, the control unit 150 may also select other lighting units 110 that are not on the side facing the target position 300 but that project the illumination light from being blocked by the object 400 to project auxiliary light. For example, in the example of FIG. 9, the lighting unit 110 in the rear left row of the vehicle 10 is selected to be adjusted and activated to project illumination light, this alternative projected path being shown in dashed lines in FIG. 9.
The shielding detection unit can also detect whether the illumination light to be projected is shielded by the vehicle body. The walking route guidance system 100 may select an appropriate illumination mode according to whether the guidance light is blocked by the vehicle body.
Further, in the case where only the driver 200 is present in the driving seat of the vehicle 10, the control unit 150 may select any one of the lighting units 110 on the left and right sides of the front row of the vehicle 10.
