All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present application, and the present application embodiment is not described in detail again.
Fig. 3 is a flowchart of a lane change control method of an automobile according to an embodiment of the present application, and referring to fig. 3, the method includes the following steps.
Step 301: the automobile acquires the environmental information of the environment where the automobile is located through a microwave radar and a camera which are installed on the automobile.
After the automobile is ignited, the driver can continue to change the lane at any time according to the current road condition, and whether the lane change of the automobile is safe or not is related to the environment condition of the automobile. Therefore, in order to safely change lanes of the automobile, the automobile can acquire environmental information of the environment where the automobile is located through a microwave radar and a camera which are installed on the automobile.
As an example, in order to be able to acquire the environmental information in time, the automobile may acquire the environmental information in real time during driving, may acquire the environmental information every specified time interval, and/or may acquire the environmental information when a lane change instruction is received.
It should be noted that the lane change instruction may be triggered by a driver acting on a display screen, an instruction button, a key, a switch, or the like of the automobile through a specified operation, where the specified operation may be a click operation, a slide operation, a toggle operation, a twist operation, a voice operation, or the like. For example, the specified operation may be an operation of dialing a turn signal.
It should be noted that the specified time interval can be set in advance according to the requirement, for example, the specified time interval can be 5 minutes, 3 minutes, 1 minute, and so on.
Step 302: when the automobile detects lane changing operation, whether the automobile meets lane changing conditions is determined according to the environmental information.
Because the automobile may not be dangerous or dangerous when changing lanes in the current environment, the automobile needs to determine whether the automobile meets the lane changing condition according to the environmental information when detecting the lane changing operation in order to avoid the danger in the lane changing process.
It should be noted that the lane change operation may include receiving a lane change instruction, receiving a lane change control operation of a steering wheel, and the like.
As an example, the operation of the automobile determining whether the automobile satisfies the lane change condition according to the environment information may be: carrying out image detection on the environment information; when other automobiles exist in the lane indicated by the lane changing operation and the distance between the other automobiles and the automobile is smaller than or equal to the safety distance threshold value, determining that the automobile does not meet the lane changing condition; and when detecting that no other automobile exists in the lane indicated by the lane changing operation, or other automobiles exist and the distance between the other automobiles and the automobile is greater than the safe distance threshold value, determining that the automobile meets the lane changing condition.
When the lane indicated by the lane changing operation is detected to be provided with other automobiles, and the distance between the other automobiles and the automobile is larger than the safe distance threshold value, the automobile is determined to meet the lane changing condition; when other automobiles exist in the lane indicated by the lane changing operation and the distance between the other automobiles and the automobile is smaller than or equal to the safe distance threshold value, the lane changing of the automobile is indicated to be in a collision risk, and therefore the fact that the automobile does not meet the lane changing condition can be determined.
It should be noted that the safe distance may be set in advance according to requirements, and the safe distance may meet the corresponding national standard, for example, the safe distance may be 3 meters, 4 meters, and so on.
In some embodiments, since there may be a dangerous car in the lane indicated by the lane change operation, and at this time, if the driver wants to change the lane, a traffic accident may occur, so when there is a dangerous car in the lane indicated by the lane change operation, that is, when the car does not satisfy the lane change condition, the car is controlled to stop changing the lane, and the operation of step 301 is returned to until the car satisfies the lane change condition, and then the operation of step 303 is performed. That is, when the vehicle does not satisfy the lane change condition, the vehicle may suspend the lane change operation and continuously detect the environmental information around the vehicle, and when it is determined that the vehicle satisfies the lane change condition according to the environmental information, the vehicle may be continuously controlled to perform the lane change operation.
As an example, since the automobile does not change the lane, the driver may be suspected of having a problem with the automobile, and the automobile perceptibility and the automobile viscosity of the driver are reduced, so that, in order to avoid such a problem, when the automobile does not meet the lane change condition, after the automobile is controlled to stop changing the lane, the automobile may prompt the driver to change the lane in the current environment through the first prompt message, so as to avoid the safety risk.
As an example, the car may be prompted by the states of the alarm bell and the alarm lamp, for example, when there is one alarm lamp, the car may be prompted by flashing or flashing the alarm lamp, when there are two alarm lamps, if there is a dangerous car in the left lane and the left lane needs to be changed to the left, the car may be prompted by flashing or flashing the left alarm lamp, and if there is a dangerous car in the right lane and the car needs to be changed to the right, the car may be prompted by flashing or flashing the right alarm lamp; and/or, two alarm lamps are flashed or normally lighted at the same time; and/or the automobile can also display the first prompt message on the instrument or the display screen.
Step 303: and when the automobile meets the lane changing condition, controlling the automobile to change lanes.
As an example, when the automobile controls the automobile to change lanes, the automobile may obtain steering information of the automobile, where the steering information includes steering angle information and a steering direction; and controlling a steering lamp of the automobile to be turned on according to the steering direction, and controlling a steering wheel of the automobile to rotate according to the corner information so as to finish lane change control of the automobile.
Note that the steering direction may be obtained after detecting the lane change operation. The rotation angle information may be set in advance according to requirements, for example, the rotation angle information may be 3 degrees, 5 degrees, 6 degrees, and the like. Of course, since the vehicle may have a certain angle of the steering wheel before controlling the steering wheel to rotate, the steering angle information may be determined according to the difference between the reference steering angle and the current angle of the steering wheel. That is, the current angle of the steering wheel is subtracted from the reference angle of rotation to obtain the angle of rotation information. The reference rotation angle may be set in advance according to the requirement. For example, the reference rotation angle may be 5 degrees, 10 degrees, or the like. When the current angle of the steering wheel is 3 degrees, the rotation angle information may be 2 degrees, 7 degrees, or the like.
In some embodiments, when the vehicle meets the lane change condition, the driver is required to take over the vehicle in time for driving safety after controlling the vehicle to change lanes. Therefore, whether the automobile is taken over by the driver can be detected within the preset time after the lane change is finished, and when the automobile is not taken over by the driver who detects the automobile, the driver can be prompted to take over the automobile through the second prompt information.
It should be noted that the automobile may prompt in a manner that the second prompt message and/or the meter and the second prompt message are/is displayed on the display screen through voice. And/or the driver is prompted by the alarm bell in a normal sounding mode, namely, when the driver does not take the automobile, the alarm bell rings, and when the driver takes over the automobile, the alarm bell stops.
In some embodiments, because some dangerous vehicles with a relatively high speed may approach the vehicle in the lane changing process of the vehicle, whether other dangerous vehicles approach the vehicle may also be detected in the lane changing process of controlling the vehicle, and when the vehicle enters another vehicle in the environment detection area, the vehicle is controlled to stop lane changing, or the vehicle is controlled to return to the original lane. And/or the driver may not want to change lane midway and performs the lane change termination operation, so that the driver can control the automobile to terminate the lane change or control the automobile to return to the original lane when receiving the lane change termination instruction in the process of controlling the automobile to change the lane.
It should be noted that the environment detection area may be an area within the detection range of the microwave radar and the camera.
In some embodiments, the automobile may have a fault, and when the automobile has a fault, the accuracy of the detection of the environmental information or the safety of lane change may not be ensured, so that before the detection of the environmental information of the automobile, the safety self-inspection of the automobile can be performed to obtain the self-inspection information of the automobile; when it is determined that the vehicle is in a safe state based on the self-inspection information of the vehicle, the operation of step 301 described above is performed.
It should be noted that the self-check of the automobile may include self-check of each system, circuit, engine, oil tank, etc. in the automobile, and the self-check information may be information on whether each system is in a normal state, information on whether the circuit is safe, information on whether the engine is in a normal state, information on whether the oil tank is in a normal state, etc.
As a practical example, when it is determined that the vehicle is not in the safe state based on the vehicle self-inspection information, a third prompt message may be used to prompt that the vehicle self-inspection is not qualified and the vehicle is currently in the unsafe state, and a fault code is recorded, where the third prompt message is used to describe fault information.
It should be noted that the automobile may prompt in a manner that the third prompt information is played by voice or displayed by an instrument or a display screen.
In the embodiment of the application, the automobile can acquire the environmental information of the environment where the automobile is located, and when the automobile meets the lane changing condition according to the environmental information, the automobile is controlled to automatically change the lane, and when the lane changing condition is not met, the lane changing operation of the automobile can be suspended, and the lane changing is carried out again when the passing lane condition is met. The situation that a driver cannot observe dangerous automobiles in the automobile blind area in the lane changing process is improved, the fussy operation that the driver manually changes lanes is improved, the workload of the driver is reduced, the lane changing efficiency and safety of the automobile are improved, and the possibility of traffic accidents is reduced.
