Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

It should be noted that, all actions for acquiring signals, information or data in the present application are performed under the condition of conforming to the corresponding data protection rule policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.

When more than two vehicles come in succession behind the side of vehicle, the early warning system in the related art can not distinguish early warning with an coming vehicle. When a closer oncoming vehicle leaves the collision risk area, the driver may consider that there is no danger and the lane is suddenly changed, or the passenger may consider that there is no danger and the door is suddenly opened, and then traffic accidents are most likely caused. In view of this, the inventors have conceived a vehicle early warning method capable of prompting for multi-target approach behind a vehicle.

Fig. 1 is a flow chart illustrating a vehicle warning method according to an exemplary embodiment. Referring to fig. 1, the method includes the following steps.

In step S11, a moving object behind the vehicle is monitored.

Fig. 2 is a diagram illustrating a scenario of monitoring a moving object according to an exemplary embodiment. As shown in fig. 2, the vehicle a is a vehicle, and there are two vehicles (vehicle B and vehicle C) in front and rear within a predetermined range (within a broken line frame) of the vehicle a. When the vehicle a is parked at the roadside, if the driver or the left passenger in the vehicle a opens the door at this time, the vehicle a is liable to collide with the vehicles B and C. In the related art, only one vehicle is monitored, but two vehicles are not monitored, and when the vehicle B is driven away from the vehicle a, the passenger may be the absence of the vehicle, and the door opening is quite dangerous.

Specifically, a moving object (e.g., a vehicle) in the rear may be monitored with a speed sensor, a distance sensor, or the like that is mounted outside the vehicle. For example, millimeter wave radar may be used for monitoring. Millimeter wave radars are particularly sensitive to the radial velocity of a target and can accurately distinguish between rear moving objects of different velocities (relative to the speed of the host vehicle) with ultra-high doppler resolution. For example, the radar may determine the number of moving objects from a different plurality of speeds determined by the return signal. The intelligent image recognition technology can be used for determining a plurality of vehicles at the rear, obtaining the speed of each vehicle, and fusing the data obtained by monitoring different sensors to obtain the final speed of the vehicle at the rear.

It will be appreciated by those skilled in the art that the speed referred to in this scenario, unless otherwise indicated, is a relative speed with respect to the speed of the vehicle.

In step S12, when it is detected that at least two moving objects approach the vehicle, a first hint message indicating that there is multi-target approach is output.

The first prompting message may be a light, a flashing light, a voice, a beeping sound, etc. For example, outputting the first alert message may include one or more of: controlling the indicator lamp on the outer rearview mirror to be lightened or twinkle; the indicator light on the control door handle lights up or blinks; the first audio message is output.

According to the technical scheme, the mobile objects behind the vehicle are monitored, and when at least two mobile objects are detected to approach the vehicle, a first prompt message for indicating that multiple targets approach is output. In this way, the driver or the passenger can know the quantity of the rear moving objects according to the first prompt message indicating that the multiple targets are approaching, so as to actively take necessary measures, avoid accidents caused by the approach of the multiple moving objects at the rear, and improve the driving safety.

Fig. 3 is a flowchart illustrating a vehicle warning method according to another exemplary embodiment. As shown in fig. 3, on the basis of fig. 1, when at least two moving objects are detected to approach the vehicle, the step S12 of outputting a first hint message indicating that there is multi-target approach includes the following steps.

In step S121, the speed of each moving object is acquired.

In step S122, a moving object whose speed is greater than a preset threshold is determined as a target object.

In step S123, when the number of objects is 2 or more, a first hint message indicating that there are multiple objects approaching is output.

The moving object with the speed greater than the preset threshold value can be considered to have a certain threat to the safety of the vehicle. For example, when a vehicle is opened, a rear vehicle (moving object) traveling at a large speed may cause damage to the doors of the vehicle and even to a person who gets off the vehicle, and when the vehicle turns, the rear vehicle traveling at a large speed may cause damage to the vehicle. The preset threshold may be a speed determined in advance from experimentation or experience.

If the speed of the moving object is not greater than the preset threshold, the moving object is considered to be not threatening the safety of the vehicle, and can be indeterminate as the target object.

In this embodiment, the moving object is divided into a target object with a security threat to the host vehicle and other objects without a threat by the speed of the moving object, and a first prompt message for indicating that multiple targets are approaching is output for the moving object with a security threat, so that the prompt message has a more obvious prompt function.

In yet another embodiment, the method may further comprise: the moving object in the rear left and rear right of the vehicle is monitored, or when one side of the vehicle is determined as the execution side, the moving object in the rear side of the execution side is monitored, and the execution side is the side of opening the door or turning.

Specifically, in the foregoing embodiment, the detection may be performed with the speed detection device provided at the rear of the vehicle, resulting in the speed of the moving object at the rear of the vehicle. When the moving object reaches the vehicle side rear (left rear or right rear), detection can be performed with a speed detection device provided at the vehicle side.

The execution side is the side of opening the door or turning. For example, when the driver or passenger presses an unlock key of the left door, the left door is instructed to unlock, the left side is the execution side, or when the driver turns on the left turn signal, the left side is the execution side; alternatively, when the driver turns the steering wheel to the left, the left side is the execution side. When the left side of the vehicle is determined as the execution side, only the moving object behind the left side may be monitored, and when the right side of the vehicle is determined as the execution side, only the moving object behind the right side may be monitored, or both the moving objects behind the left and right sides may be monitored at the same time.

And outputting a first prompt message when the number of the targets at the rear, the rear left side and the rear right side of the vehicle is more than or equal to 2.

In this embodiment, it is possible to detect a moving object behind the vehicle side, or to monitor only a moving object behind the side of the execution side, so that the protection of the vehicle is more accurate.

In yet another embodiment, the method may further comprise: when it is detected that only one moving object approaches the vehicle, a second prompt message indicating that a single object approaches is output.

When it is detected that only one moving object is approaching the vehicle, the output second hint message is different from the first hint message. The second prompting message can also be a lighting lamp, a flashing light, a voice, a beeping sound and the like. For example, when one vehicle is detected on the left rear side of the vehicle and the moving speed is greater than the speed threshold, the control turns on one indicator lamp on the left door handle of the vehicle, and when two vehicles are detected on the left rear side of the vehicle and the moving speed is greater than the speed threshold, the control turns on two indicator lamps on the left door handle of the vehicle. When the passenger sees that both lamps are on, indicating that there is more than one vehicle behind, special attention is paid to see the clear condition and then the door is opened.

Outputting the second hint message may include one or more of: controlling a plurality of indicator lamps on the external rearview mirrors on the sides of the plurality of moving objects to light or flash; controlling a plurality of indicator lamps on the door handles on the sides where the plurality of moving objects are located to light or flash; and outputting the audio message. The first alert message and the second alert message may be audio messages of different frequencies. For example, the first hint message is more frequent than the second hint message, and more acute and dangerous situations are revealed.

In this embodiment, the single-target approaching cue message and the multi-target approaching cue message are distinguished, so that the user can easily distinguish the magnitude of the danger caused by the rear moving object, so as to take the security measures in time.

In yet another embodiment, the method further comprises:

determining the current running state of the vehicle;

when the number of the targets is greater than or equal to 2, the current running state of the vehicle is running, and the targets are on the execution side of steering, the steering damping of the steering wheel is increased to a preset damping.

The running state of the vehicle may include running and stopping. For example, when the current vehicle speed is greater than a predetermined vehicle speed threshold (e.g., 3 km/h), the current running state may be determined to be running; when the current vehicle speed is less than or equal to a predetermined vehicle speed threshold, it may be determined that the current running state is in a stop.

The execution side of the steering indicates the side on which the vehicle is to be steered. For example, when the driver turns on the left turn signal, the left side is the execution side of the steering, and when the driver turns on the right turn signal, the right side is the execution side of the steering. Alternatively, when the driver turns the steering wheel leftward, the left side is the steering execution side, and when the driver turns the steering wheel rightward, the right side is the steering execution side.

In order to avoid a collision accident of the vehicle caused by the driver just driving the steering wheel when the rear vehicle overtakes during running of the vehicle, in this embodiment, the steering damping of the steering wheel is increased in this case. Steering damping of the steering wheel is used to counter steering torque applied by the driver. The steering wheel does not rotate when the steering torque applied by the driver is less than the steering damping of the steering wheel, and the steering wheel rotates when the steering torque applied by the driver is greater than the steering damping of the steering wheel. Therefore, increasing the steering damping of the steering wheel can cause the driver to feel a large resistance, but the steering wheel is not completely immobilized because the steering damping of the steering wheel is only increased to a predetermined damping and is not completely locked. When the driver still intends to steer after the damping is felt to be increased, a larger force may be used to complete the steering. The predetermined damping may be derived from experiments in advance.

In this embodiment, in the above-described case, the control increases the steering damping of the steering wheel, and functions not only as a prompt but also to some extent as a hindrance to dangerous driving.

In yet another embodiment, the method further comprises:

determining the current running state of the vehicle;

and when the number of the targets is greater than or equal to 2, the current running state of the vehicle is in parking, and the targets are on the execution side of the door opening, suspending execution of the unlocking instruction of the door opening until a preset time length is reached or a forced unlocking instruction is received.

In order to avoid a collision accident of the vehicle caused by the driver or the passenger opening the door exactly when the rear vehicle passes while the vehicle is stopped, in this embodiment, the execution of the unlock instruction is delayed for a predetermined period of time or the passenger is required to execute the forced unlock instruction. The predetermined time period may be obtained in advance from a test, and may be set as a time period during which the vehicle in a predetermined range laterally rearward of the vehicle can exit the vehicle. When the vehicle in the preset range behind the vehicle side exits the vehicle, the vehicle door is unlocked at the moment that the risk of collision of the vehicle is avoided when the vehicle door is opened.

The unlocking instruction is executed in a delayed mode, a driver or a passenger can feel that the vehicle door is opened with larger resistance, but the vehicle door can be unlocked only by not delaying the time, and the vehicle door can be unlocked under the condition that the time is not delayed by sending out the forced unlocking instruction. The forced unlock instruction may trigger generation in a more aggressive manner than the unlock instruction.

In this embodiment, in the above-described case, the delay execution of the unlock instruction or the forced unlock instruction is required to unlock the door, not only plays a role of prompting, but also plays a role of hindering dangerous driving to some extent.

In yet another embodiment, the unlocking instruction is generated when the electronic switch of the vehicle door is pressed for a time period greater than a predetermined first time period, and the forced unlocking instruction is generated when the electronic switch is pressed for a time period greater than a predetermined second time period, wherein the first time period is less than the second time period.

That is, the forced unlock command may trigger generation by pressing an electronic switch of the door for a greater duration than the unlock command. That is, the unlocking condition of the electronic door is adjusted to further verify the intention of the passenger to open the door. The second time period is less than the predetermined time period. In this embodiment, the passenger needs to take longer to unlock the door than the electronic switch which normally presses the door, further confirming the passenger's willingness to open the door, and improving the safety of opening the door.

In yet another embodiment, the unlock command is generated when a torque applied by the mechanical switch of the vehicle door is greater than a predetermined first torque threshold, and the forced unlock command is generated when a torque applied by the mechanical switch is greater than a predetermined second torque threshold, the first torque threshold being less than the second torque threshold.

That is, the forced unlock command may trigger generation by applying a greater torque to the mechanical switch of the door than the unlock command. That is, the unlocking condition of the mechanical door is adjusted to further verify the passenger's intention to open the door. The first torque threshold and the second torque threshold may be empirically derived. In this embodiment, the passenger needs to unlock the vehicle door with a larger torque than the torque applied to the mechanical switch at ordinary times, further confirming the passenger's willingness to open the door, and improving the safety of opening the door.

Fig. 4 is a flowchart illustrating a vehicle warning method according to still another exemplary embodiment. Referring to fig. 4, after the vehicle is started, the vehicle early warning system can perform self-detection, and if abnormal, the vehicle early warning system performs fault warning; if normal, the system stands by. During standby, the moving speeds of the moving objects on the left and right rear sides are monitored by the millimeter wave radar on the vehicle, the vehicle speed is monitored by the vehicle speed sensor, and whether there is an unlock instruction of the vehicle door is monitored by the vehicle lock sensor.

If at least two moving objects are arranged behind the vehicle and the moving speed is greater than a preset speed threshold, the system is activated, primary early warning of multi-target indication is executed, a first prompt message is output, a door handle flashing lamp in the cabin is used for warning, and a rearview mirror frame flashing lamp outside the cabin is used for warning.

If the driver is detected to turn to a lane change (the steering wheel is applied with torque), performing secondary early warning of multi-target indication, and increasing the steering damping of the steering wheel. If the received steering wheel applied torque is greater than the increased predetermined damping (forced steering by the driver), a steering lane change is performed while still performing an in-cabin warning and an out-of-cabin warning.

If the driver or the passenger is monitored to unlock the door lock (trigger the unlocking instruction), the secondary early warning of the multi-target indication is executed, and the execution of the unlocking instruction is suspended until the preset time is reached or the forced unlocking instruction is received. And before the preset time is reached, if a forced unlocking instruction (forced unlocking) is generated, the vehicle door is unlocked, and meanwhile, the in-cabin warning and the out-of-cabin warning are still executed.
