[0041] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0042] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0043] This paper proposes a turn signal control method that conforms to the driving intention, considers more detailed driving scenarios and provides a control method, and comprehensively considers the influence of steering wheel angle on turn signal control in some special scenarios.

[0044] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, such as a turn signal control device. This embodiment and the following embodiments will be described below using a turn signal control device as an example.

[0045] Based on this, the embodiment of the present application provides a turn signal control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the turn signal control device method of the present application.

[0046] In this embodiment, the turn signal control device method includes steps S10 to S20:

[0047] Step S10, obtaining a turn signal lever signal, a steering wheel angle signal, and a smart driving turn signal request signal;

[0048] It should be noted that the turn signal switch is self-resetting, meaning that after manually shifting to the lane change gear or the steering gear and releasing it, the lever will automatically return to the center position. The turn signal switch sends corresponding signals based on the current switch position, including left lane change, right lane change, left turn, right turn, and off. The steering wheel angle signal indicates the degree of steering wheel rotation;

[0049] The intelligent driving turn signal request signal is the ADAS (automatic driving assistance system) request.

[0050] Step S20: Determine the corresponding turn signal controller instruction based on the turn signal lever signal, the steering wheel angle signal, and the intelligent driving turn signal request signal, and control the turn signal through the turn signal controller instruction.

[0051] In the specific implementation, the turn signal control is carried out by the body controller which receives the turn signal lever signal, steering wheel angle signal and intelligent driving turn signal request signal, makes a comprehensive judgment and then issues a turn signal controller instruction. After receiving the turn signal control instruction, the lamp drives the turn signal on / off.

[0052] The step S20 further includes: when the left turn light is in a continuous flashing state and the received intelligent driving turn light request signal is a right turn light request signal, the right turn light controller instructs the left turn light to switch from continuous flashing to continuous flashing of the right turn light.

[0053] It should be noted that when the left turn signal is flashing or flashing three times and receives a right turn signal request signal or ADAS requests a right turn, it will switch to a state where the right turn signal continues to flash. Similarly, when the right turn signal is flashing or flashing three times and receives a left turn signal request signal or ADAS requests a left turn, it will switch to a state where the left turn signal continues to flash. This is the lane change process.

[0054] It should be understood that the manual turn signal request and the intelligent driving turn signal request are set to the same priority, and the later request is executed.

[0055] like Figure 2 As shown, Figure 2 This is the integrated control logic diagram of the turn signal of this application. Taking the left turn signal as an example, the manual turn signal control method is as follows:

[0056] Turn on: Manually push the turn signal lever downward. After the body controller receives the left turn switch signal, it controls the left turn signal to turn on and keep it working.

[0057] Close: Push the lever to the right to change lanes; the steering wheel is rotated counterclockwise by more than 30° and then reversed to less than 20°; the body controller receives any of the above conditions and controls the turn signal to be turned off.

[0058] Smart driving request turn signal:

[0059] On: When automatically changing lanes to the left, the intelligent driving system sends a left turn signal request signal. After receiving the signal, the body controller turns on the left turn signal and keeps it working.

[0060] Turn off: Push the lever to the right to change lanes; the intelligent driving system requests to turn off the turn signal; the body controller receives any of the above and controls to turn off the turn signal.

[0061] Furthermore, the strategy also includes: monitoring the real-time speed of the vehicle;

[0062] When the speed exceeds a first preset speed threshold, controlling the flashing frequency of the turn signal lamp to increase;

[0063] It should be noted that the first preset threshold can be calibrated based on the environment, such as 60km / h, 80km / h.

[0064] In specific implementation, when the vehicle speed exceeds a certain threshold, the system will increase the flashing frequency of the turn signal to ensure that other vehicles can notice the turn signal in time when driving at high speed.

[0065] When the speed is less than a second preset threshold, the flashing frequency of the turn signal is controlled to decrease, wherein the first preset threshold is greater than the second preset threshold.

[0066] The second preset threshold can be calibrated based on the environment, such as 20km / h, 30km / h.

[0067] In a specific implementation, in urban congestion or when driving at low speeds, the system may reduce the flashing frequency to reduce visual interference to surrounding vehicles and pedestrians.

[0068] It should be understood that at night or in low visibility conditions such as fog and rain, this strategy can also automatically increase the brightness of the turn signal to improve vehicle visibility, while reducing the flashing frequency of the turn signal to avoid causing interference to other drivers due to excessive flashing.

[0069] This embodiment provides a turn signal control method that addresses the issue of a turn signal being turned off due to a small steering wheel adjustment while the user is turning a vehicle. It also addresses the issue of a turn signal being turned off due to a full turn of the steering wheel before the vehicle completes a U-turn. This method better reflects the user's intention to use the turn signal, makes it easier for other traffic participants to identify the vehicle's direction, and reduces the risk of traffic accidents.

[0070] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 3 , step S20, the turn signal control method further includes steps S201 to S205:

[0071] Step S201, when the turn signal lever signal is a left lane change switch signal, the left turn signal controller is used to control the left turn signal to flash a preset number of times;

[0072] It should be noted that this embodiment is directed to a control method for a left turn signal of a vehicle.

[0073] It should be understood that in this strategy, when a left lane change switch signal is received, the left turn signal is immediately switched from the off state to flashing three times;

[0074] Furthermore, when the left turn signal is flashing a preset number of times, upon receiving a right lane change switch signal, the right turn signal is immediately switched to flashing three times.

[0075] Step S202: When the received second turn signal lever signal is a left turn switch signal, or when the received intelligent driving turn signal request signal is a left turn signal request signal, the state of the left turn signal is controlled to switch to continuous flashing;

[0076] Step S203, when the received third turn signal lever signal is a left lane change switch signal or a right lane change switch signal, controlling the left turn signal to be turned off by turning off the turn signal controller instruction;

[0077] Step S204, when the steering wheel angle signal is detected to show that the steering wheel is rotated to a first preset angle, and the steering wheel angle signal is detected to show that the steering wheel is rotated in the opposite direction to a second preset angle, the turn signal controller is controlled to turn off by turning off the turn signal controller, wherein the first preset angle is greater than the second preset angle.

[0078] It should be noted that when Intelligent Driving requests the turn signal, the turn signal remains on after the steering wheel returns to its normal position. This strategy has the advantage of preventing situations where the turn signal is accidentally turned off during Intelligent Driving's rapid lane changes, even if the lane change is incomplete due to the large steering range. This allows Intelligent Driving to control the turn signal and then turn it off after determining that the lane change is complete.

[0079] In practice, the turn signal is turned off when the steering wheel angle exceeds 30° and then returns to less than 20°. This strategy has the following advantages: 1) It prevents the turn signal from turning off before the maneuver is complete (e.g., turning the vehicle twice and then back to one); 2) A 10° steering angle hysteresis prevents the turn signal from being accidentally turned off due to minor vibrations during steering.

[0080] It should be understood that this embodiment is a method for controlling the left turn signal of a vehicle. Therefore, the positive direction at this time is rotating the steering wheel counterclockwise, and the negative direction is rotating the steering wheel clockwise.

[0081] Step S205: When the intelligent driving turn signal request signal is a turn signal off request signal, the turn signal is controlled to be off by turning off the turn signal controller instruction.

[0082] It should be noted that, if the vehicle body controller receives any one of the three conditions of steps S203, S204 and S205 as being met, it controls the turn signal to be turned off.

[0083] It should be understood that the manual turn signal request and the intelligent driving turn signal request are set to the same priority, and the later request is executed.

[0084] This embodiment provides a turn signal control method that addresses the issue of turn signals being accidentally turned off in certain special scenarios during automatic lane changes. It also enables the driver to complete the entire lane change process of turning on the turn signal, automatically changing lanes, and then turning off the turn signal in a single operation. This method better aligns with the user's intention to use the turn signal, providing greater convenience, a better driving experience, and a reduced risk of traffic accidents.

[0085] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction and will not be described in detail later. Figure 4 , step S20, the turn signal control method further includes steps S210 to S250:

[0086] Step S210, when the turn signal lever signal is a right lane change switch signal, the right turn signal controller is used to control the right turn signal to flash a preset number of times;

[0087] It should be noted that this embodiment is directed to a method for controlling a right turn signal of a vehicle.

[0088] It should be understood that in this strategy, when a right lane change switch signal is received, the right turn signal is immediately switched from the off state to flashing three times;

[0089] Furthermore, when the right turn signal is flashing a preset number of times, upon receiving a left lane change switch signal, the left turn signal is immediately switched to flashing three times.

[0090] Furthermore, when the left turn signal is flashing a preset number of times, upon receiving a right lane change switch signal, the right turn signal is immediately switched to flashing three times.

[0091] Step S220: When the received second turn signal lever signal is a right turn switch signal, or when the received intelligent driving turn signal request signal is a right turn signal request signal, controlling the state of the right turn signal to switch to continuous flashing;

[0092] Step S230, when the received third turn signal lever signal is a right lane change switch signal or a left lane change switch signal, controlling the right turn signal to be turned off by turning off the turn signal controller instruction;

[0093] Step S240, when the steering wheel angle signal is detected to show that the steering wheel is rotated to a first preset angle, and when the steering wheel angle signal is detected to show that the steering wheel is rotated in the opposite direction to a second preset angle, the turn signal is controlled to be turned off by turning off the turn signal controller instruction, wherein the first preset angle is greater than the second preset angle.

[0094] It should be noted that when Intelligent Driving requests the turn signal, the turn signal remains on after the steering wheel returns to its normal position. This strategy has the advantage of preventing situations where the turn signal is accidentally turned off during Intelligent Driving's rapid lane changes, even if the lane change is incomplete due to the large steering range. This allows Intelligent Driving to control the turn signal and then turn it off after determining that the lane change is complete.

[0095] In practice, the turn signal is turned off when the steering wheel angle exceeds 30° and then returns to less than 20°. This strategy has the following advantages: 1) It prevents the turn signal from turning off before the maneuver is complete (e.g., turning the vehicle twice and then back to one); 2) A 10° steering angle hysteresis prevents the turn signal from being accidentally turned off due to minor vibrations during steering.

[0096] It should be understood that this embodiment is a method for controlling the right turn signal of a vehicle. Therefore, the positive direction at this time is to rotate the steering wheel clockwise, and the negative direction is to rotate the steering wheel counterclockwise.

[0097] Step S250: When the intelligent driving turn signal request signal is a turn signal off request signal, the turn signal is controlled to be off by turning off the turn signal controller instruction.

[0098] It should be noted that, if the vehicle body controller receives any one of the three conditions of steps S230, S240 and S250 as being met, it controls the turn signal to be turned off.

[0099] It should be understood that the manual turn signal request and the intelligent driving turn signal request are set to the same priority, and the later request is executed.

[0100] This embodiment provides a turn signal control method, analyzes various application scenarios, and satisfies driving intentions to the greatest extent possible, clearly informing surrounding traffic participants of the vehicle's movement direction, avoiding situations where the turn signal is not turned on or turned off by mistake, thereby improving driving safety and reliability and enhancing the user's driving experience.
