Step S802, if the steering wheel rotates towards the first rotating direction, whether the steering wheel is back-aligned or not is detected at a second preset time after the steering wheel rotates.
As shown in fig. 6, if the control device detects that the right turn signal of the vehicle 20 is turned on at time t2 and immediately detects the state of the steering wheel at time t2, and if the steering wheel is turned in the first turning direction, for example, to the right at time t2, it detects whether the steering wheel is turned back at a second predetermined time after the turning, for example, at time t 3.
And step S803, if the steering wheel is in a return state and lasts for a first preset time, judging whether the steering lamp is in an on state.
And step S804, if the steering lamp is in the on state, turning off the steering lamp.

In the embodiment, after the steering lamp of the vehicle is turned on, the state of the steering wheel of the vehicle is detected, if the steering wheel rotates to the first rotating direction, whether the steering wheel returns to the right state is detected at the second preset time after the rotation, if the steering wheel is in the returning state and continues for the first preset time, whether the steering lamp is in the on state is further judged, if the steering lamp is in the on state, the steering lamp is not turned off after the vehicle turns to the first rotating direction, and the steering lamp is turned off at the moment, so that the steering wheel does not need to rotate by a large angle, the steering lamp can be controlled to return, and the problem that the steering lamp cannot return due to the fact that the rotating angle of the steering wheel is not large enough is solved.
The embodiment of the invention provides a control method of a turn signal lamp. Fig. 9 is a flowchart of a control method of a turn signal according to another embodiment of the present invention. As shown in fig. 9, on the basis of the embodiment shown in fig. 1, the method in this embodiment may include:
step S901, detecting a state of a steering wheel of a vehicle after a turn signal of the vehicle is turned on.
The specific principle and implementation of step S901 are the same as those of step S101, and are not described herein again.

As shown in fig. 10, if the control device detects that the right turn signal of the vehicle 20 is turned on at time t2 and detects the state of the steering wheel at time t3 after time t2, and if the steering wheel is turned in the first turning direction, for example, to the right at time t3 and is turned in the opposite direction to the first turning direction, for example, to the left at time t4, it detects whether the steering wheel is turned back at a second preset time, for example, at time t5 after the steering wheel is turned to the left. Wherein the opposite direction of the first rotational direction is denoted as the second rotational direction.

As shown in fig. 10, assuming that the control device detects that the right turn signal of the vehicle 20 is turned on at time t2 and detects the state of the steering wheel at time t3 after time t2, if the steering wheel is turned in the first turning direction, for example, to the right at time t3 and is turned in the opposite direction to the first turning direction, for example, to the left at time t4, the angle of turning the steering wheel to the left is detected, and if the angle is smaller than a preset angle, that is, the angle of turning the steering wheel to the left is small, whether the steering wheel is turned back to the right is detected at a second preset time after turning the steering wheel to the left, for example, at time t 5.
And step S903, if the steering wheel is in a return state and lasts for a first preset time, judging whether the steering lamp is in an on state.

If the steering wheel is in the return state at the time t5 and the steering wheel continues to be in the return state for the first preset time, whether the right turn light is in the on state is further judged, if the right turn light is still in the on state, the right turn light is not turned off after the lane change of the vehicle 20 is completed, and at the moment, the control device controls the right turn light to be turned off.
In addition, the method described in this embodiment is also applicable to a scenario where the steering wheel rotates left first and then rotates right and returns to the right, and the specific principle is the same as that of the method described in this embodiment, and is not described here again.
In the embodiment, after the steering lamp of the vehicle is turned on, the state of the steering wheel of the vehicle is detected, if the steering wheel rotates in the first rotating direction and then rotates in the second rotating direction, and the angle of the steering wheel rotating in the second rotating direction is smaller, then whether the steering wheel returns to the right state is detected within the second preset time after the steering wheel rotates in the second rotating direction, if the steering wheel is in the return to the right state and continues for the first preset time, whether the steering lamp is in the on state is further judged, if the steering lamp is in the on state, the vehicle turns to the first rotating direction and the steering lamp is not turned off after the return to the right state, and at the moment, the steering lamp is turned off, so that the steering wheel does not need to rotate by a larger angle, the steering lamp can be controlled to return to the right state, and the problem that the steering lamp cannot return to the right state due to an insufficient rotating angle.
The embodiment of the invention provides a control method of a turn signal lamp. Fig. 11 is a flowchart of a method for controlling a turn signal according to another embodiment of the present invention. As shown in fig. 11, on the basis of the embodiment shown in fig. 1, the method in this embodiment may include:
and step S1101, detecting a state of the steering wheel of the vehicle after a turn signal of the vehicle is turned on.
The specific principle and implementation of step S1101 are consistent with those of step S101, and are not described herein again.
And step S1102, detecting whether the vehicle runs on the expressway.
In the present embodiment, when the vehicle 20 travels on a highway, the turning angle of the steering wheel is small when the vehicle 20 changes lanes and turns. In order to control the turn signal to return accurately when the steering wheel is turned by a small angle, the control device can also detect whether the vehicle 20 is running on the highway.
Optionally, the detecting whether the vehicle runs on the expressway includes the following possible implementation manners:
one possible implementation is: acquiring the running speed of the vehicle; and if the running speed of the vehicle is greater than the preset speed, determining that the vehicle runs on the expressway.
For example, the control means may acquire the traveling speed of the vehicle 20 detected by a speed sensor in the vehicle 20 in real time, and determine that the vehicle 20 travels on an expressway when the traveling speed of the vehicle 20 is greater than a preset speed, for example, 60 km/h.
Another possible implementation is: acquiring image information of a lane where the vehicle is located, which is detected by a vision sensor arranged on the vehicle; and if the image information comprises the highway identification, determining that the vehicle runs on the highway.
For example, the vehicle 20 may further be provided with a vision sensor, which may specifically be a shooting device, the shooting device is configured to capture image information of an environment around the vehicle 20 in real time, the control apparatus obtains the image information through the shooting device, and determines whether a highway identifier exists around the lane where the vehicle 20 is located according to the image information, and if the highway identifier exists in the image information, the control apparatus determines that the vehicle 20 is traveling on a highway.
Yet another possible implementation is: acquiring the running speed of the vehicle; acquiring image information of a lane where the vehicle is located, which is detected by a vision sensor arranged on the vehicle; and if the running speed of the vehicle is greater than the preset speed and the image information comprises the highway identification, determining that the vehicle runs on the highway.
For example, the control apparatus may acquire the traveling speed of the vehicle 20 detected by a speed sensor in the vehicle 20 in real time and acquire image information of the environment around the vehicle 20 through a photographing device provided in the vehicle 20, and further, the control apparatus detects whether the traveling speed of the vehicle 20 is greater than a preset speed and whether a highway identification exists in the image information, and determines that the vehicle 20 travels on a highway if the traveling speed of the vehicle 20 is greater than the preset speed, for example, 60km/h, and if the highway identification exists in the image information.
Step S1103, if the vehicle runs on a highway, the steering wheel is in a return state and lasts for a first preset time, whether the steering lamp is in an on state is judged.
As shown in fig. 6, if the vehicle 20 is running on a highway, the control apparatus detects that the right turn lamp of the vehicle 20 is turned on at time t2, and detects the state of the steering wheel at a threshold time after time t2, for example, at time t 3. And between time t2 and time t3, the vehicle 20 has made a lane change. If the steering wheel is in the return-to-positive state at time t3 for a first preset time, for example, the steering wheel is still in the return-to-positive state until time t4, it is determined whether the right turn signal is in the on state at time t 4.
And step S1104, if the turn light is in an on state, turning off the turn light.
If the right turn signal is still on at time t4, indicating that the vehicle 20 has not turned off the right turn signal after completing the lane change, the control device controls the right turn signal to be off.
Optionally, if the turn signal lamp is in an on state, turning off the turn signal lamp includes: if the steering lamp is in an on state, detecting whether the vehicle runs in a lane; and if the vehicle runs in the lane, turning off the steering lamp.
For example, if the control device detects that the vehicle 20 is traveling in the lane at time t4, indicating that the vehicle 20 has completed the lane change and the turn signal is not turned off after the lane change, the control device controls the right turn signal to be turned off at time t4, by further detecting whether the vehicle 20 is traveling in the lane, thereby ensuring whether the vehicle 20 has actually completed the lane change.
Specifically, the detecting whether the vehicle is traveling in a lane includes: acquiring image information of a lane where the vehicle is located, which is detected by a vision sensor arranged on the vehicle; and detecting whether the vehicle runs in a lane or not according to the image information.
For example, the control apparatus acquires image information of an environment around the vehicle 20 through a photographing device provided in the vehicle 20, and determines whether the vehicle 20 is in a lane and does not crush lane boundaries or lane lines according to lane boundaries, lane lines, and the like of the lane in which the vehicle 20 is located in the image information, and determines that the vehicle 20 is driven in the lane if the control apparatus determines that the wheels of the vehicle 20 do not crush lane boundaries or lane lines and the lane boundaries or lane lines are within a preset distance range around the wheels according to the image information.
In some embodiments, the determining whether the turn signal is in an on state if the steering wheel is in a return state for a first preset time includes: and if the vehicle speed is greater than a preset speed threshold value, the steering wheel is in a return state and lasts for a first preset time, and whether the steering lamp is in an on state or not is judged.
As shown in fig. 6, if the control device detects that the right turn signal of the vehicle 20 is turned on at time t2 and immediately detects the state of the steering wheel at time t2, and if the steering wheel is turned in the first turning direction, for example, to the right at time t2, it detects whether the steering wheel is turned back at a second predetermined time after the turning, for example, at time t 3. If the driving speed of the vehicle 20 is relatively fast, for example, greater than the preset speed threshold, the lane change can be completed without rotating the steering wheel by a large angle to the right at time t2, and similarly, the steering wheel can be turned back without rotating the steering wheel by a large angle to the left after the vehicle 20 enters the right lane. Therefore, if the traveling speed of the vehicle 20 is greater than the preset speed threshold value, and the steering wheel is in the return-to-positive state at time t3 for the first preset time, for example, the steering wheel is still in the return-to-positive state until time t4, it is determined at time t4 whether the right turn lamp is in the on state, and if the right turn lamp is still in the on state, it indicates that the right turn lamp is not turned off after the lane change of the vehicle 20 is completed at a higher traveling speed, and at this time, the control device controls the right turn lamp to be turned off.
The method comprises the steps that a vehicle is determined to run on a highway, the state of a steering wheel of the vehicle is detected after the steering lamp of the vehicle is turned on, if the steering wheel is in a return state and lasts for a first preset time, whether the steering lamp is in an on state is further judged, and if the steering lamp is in the on state, the vehicle is proved not to change lanes or turn after the steering lamp is turned on, and the steering lamp is not turned off; or the turn light is not turned off after lane changing or turning is finished, and the turn light is turned off at the moment, so that the steering wheel of a vehicle running on the expressway does not need to rotate by a larger angle, the turn light can be controlled to return, and the problem that the turn light cannot return due to an insufficient rotation angle of the steering wheel is solved; in addition, when the steering lamp is in an on state, whether the vehicle is in a driving lane is detected through the visual sensor, namely whether the vehicle has completed steering or lane changing is accurately judged by combining the steering of the steering wheel and the visual sensor, so that the accuracy of controlling the steering lamp is improved.
