[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.
[0003] With the increasing use of vehicles, traffic accidents caused by vehicles are also increasing. Currently, there are generally pre-set rules for the use of motor vehicle turn signals. For example, when turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn, the left turn signal should be turned on in advance; when turning right, changing lanes to the right, returning to the original lane after overtaking, or parking on the side of the road, the right turn signal should be turned on in advance.
[0004] However, the inventors discovered that in real life, the following situation often occurs: some novice drivers or certain drivers, when they need to use their turn signals while driving, often fail to do so due to insufficient driving experience, short reaction time, or lack of awareness of the need to use turn signals. This results in drivers behind them or in another lane not being able to react in time, leading to traffic accidents. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides an automatic turn signal control method, system, medium, electronic device, and vehicle, which can prevent traffic accidents caused by drivers failing to use turn signals due to their own reasons, thereby improving driving safety and protecting the personal safety of drivers and passengers.

[0060] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0061] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0062] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0063] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.
[0064] Example 1:
[0065] like Figure 1 As shown, Embodiment 1 of the present invention provides an automatic turn signal control method, comprising the following processes:
[0066] When the vehicle is stationary, obtain the door unlock command (sensing that the vehicle is about to leave the parking spot);
[0067] Based on the door unlock command, the turn signal on one side of the vehicle is controlled to illuminate and remain illuminated for a first set time; wherein, the turn signal that should be illuminated is determined based on the relative position of the vehicle and the road.
[0068] Optionally, the door unlocking command is an unlocking command issued by the car key remote control; or, the door unlocking command is an unlocking command issued by a mobile smart terminal; or, the door unlocking command is an automatic unlocking command that is activated at a timed interval. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.
[0069] In this embodiment, preferably, the first set time is 10 seconds. It is understood that the first set time is set randomly by human intervention, or set according to specific big data conditions or the requirements of local laws and regulations, which will not be elaborated here.
[0070] In this embodiment, the turn signal that should be illuminated is determined based on the relative position of the vehicle and the road, including:
[0071] When a vehicle is parked on the right side of the road in the direction of travel, the left turn signal will illuminate. For example, if a road runs east-west and the vehicle is parked on the south edge of the road with its front facing east, the left turn signal will illuminate.
[0072] When a vehicle is parked on the left side of the road in the direction of travel, the right turn signal will illuminate. For example, if a road runs east-west and the vehicle is parked on the north edge of the road with its front facing east, the right turn signal will illuminate.
[0073] Understandably, in other implementations, an onboard image or video acquisition module can be used to collect data on the relationship between the vehicle and the road. For example, on some non-standard roads (without a center line or lane markings), the turn signal activation can be controlled based on the relative position of the vehicle and the road. By acquiring image data and combining it with a pre-set deep learning model, the vehicle's position can be quickly determined, and then, according to the vehicle's driving rules, it can be quickly determined which side's turn signal should be activated. The deep learning model here can be implemented using existing models, which will not be elaborated on here.
[0074] In this embodiment, when the vehicle is in motion, the steering wheel direction change data and angle change data are acquired. Specifically, the steering wheel angle sensor and the direction sensor are installed at the steering column of the vehicle steering wheel to acquire the corresponding data.
[0075] In this embodiment, when the steering wheel changes counterclockwise, the change angle is greater than the first set angle, and continues for a second set time (indicating that the car may be changing lanes to the left or turning left), the turn signal on the left side of the vehicle is controlled to illuminate and continue for a third set time.
[0076] When the steering wheel is turned clockwise, and the angle of change is greater than the second preset angle and continues for the fourth preset time (indicating that the car may be changing lanes to the right or turning right), the turn signal on the left side of the vehicle will be turned on and will continue for the fifth preset time.
[0077] In this embodiment, preferably, the third and fifth set times are 10-15 seconds, and the second and fourth set times can be 2 seconds (optional). It is understood that the second, third, fourth and fifth set times are set randomly by humans or according to specific big data conditions or the requirements of local laws and regulations, which will not be elaborated here.
[0078] In this embodiment, preferably, the first set angle and the second set angle can be 90° (assuming the ratio of the steering wheel rotation angle to the wheel rotation angle is 15:1, then the corresponding wheel steering angle is about 6°). The first set angle and the second set angle are both set randomly by humans or according to specific big data conditions or according to the requirements of local laws and regulations, which will not be elaborated here.
[0079] In this embodiment, if the counterclockwise angle change of the steering wheel (the angle change here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases but is still greater than the first set angle, then the turn signal on the left side of the vehicle remains unchanged; if the counterclockwise angle change of the steering wheel (the angle change here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases until it becomes zero, then the turn signal on the left side of the vehicle is turned off.
[0080] In this embodiment, if the change in the clockwise direction angle of the steering wheel (the change in angle here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases but is still greater than the second set angle, then the turn signal on the right side of the vehicle remains unchanged; if the change in the clockwise direction angle of the steering wheel (the change in angle here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases until it becomes zero, then the turn signal on the right side of the vehicle is turned off.
[0081] Optionally, in other implementations, the sensor direction and angle data are calculated to predict the trend of the vehicle's direction change in the next short period of time, thereby generating corresponding turn signal control commands and sending them to the vehicle's communication network to automatically turn on the corresponding turn signals. The short-term prediction here can be implemented using neural network algorithms. For example, after making a short-term prediction, the turn signal control is performed based on the prediction results.
[0082] Optionally, the method described in this embodiment can be executed by the vehicle's overall controller. The specific turn signal control can be implemented using the body control module (BCM). Of course, those skilled in the art can also use other on-board controllers to implement the above functions. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.
[0083] Example 2:
[0084] like Figure 2 As shown, Embodiment 2 of the present invention provides an automatic turn signal control method, comprising the following processes:
[0085] When the vehicle is in motion, data on changes in steering wheel direction and angle are acquired. Specifically, steering wheel angle and direction sensors are installed at the steering column of the vehicle's steering wheel to acquire the corresponding data.
[0086] In this embodiment, when the steering wheel changes counterclockwise, the change angle is greater than the first set angle, and continues for a second set time, the turn signal on the left side of the vehicle is controlled to light up and continue for a third set time.
[0087] When the steering wheel is turned clockwise, and the angle of change is greater than the second set angle and continues for the fourth set time, the turn signal on the left side of the vehicle will be turned on and will continue for the fifth set time.
[0088] In this embodiment, preferably, the third and fifth set times are 10-15 seconds, and the second and fourth set times can be 2 seconds. It is understood that the second, third, fourth and fifth set times are set randomly by humans or according to specific big data conditions or the requirements of local laws and regulations, which will not be elaborated here.
[0089] In this embodiment, preferably, the first set angle and the second set angle can be 90° (assuming the ratio of the steering wheel rotation angle to the wheel rotation angle is 15:1, then the corresponding wheel steering angle is about 6°). The first set angle and the second set angle are both set randomly by humans or according to specific big data conditions or according to the requirements of local laws and regulations, which will not be elaborated here.
[0090] In this embodiment, if the counterclockwise angle change of the steering wheel (the angle change here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases but is still greater than the first set angle, then the turn signal on the left side of the vehicle remains unchanged; if the counterclockwise angle change of the steering wheel (the angle change here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases until it becomes zero, then the turn signal on the left side of the vehicle is turned off.
[0091] In this embodiment, if the change in the clockwise direction angle of the steering wheel (the change in angle here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases but is still greater than the second set angle, then the turn signal on the right side of the vehicle remains unchanged; if the change in the clockwise direction angle of the steering wheel (the change in angle here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases until it becomes zero, then the turn signal on the right side of the vehicle is turned off.
[0092] Optionally, in other implementations, the sensor direction and angle data are calculated to predict the trend of the vehicle's direction change in the next short period of time, thereby generating corresponding turn signal control commands and sending them to the vehicle's communication network to automatically turn on the corresponding turn signals. The short-term prediction here can be implemented using neural network algorithms. For example, after making a short-term prediction, the turn signal control is performed based on the prediction results.
[0093] Optionally, the method described in this embodiment can be executed by the vehicle's overall controller. The specific turn signal control can be implemented using the body control module (BCM). Of course, those skilled in the art can also use other on-board controllers to implement the above functions. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.
[0094] Understandably, in other implementations, an onboard image or video acquisition module can be used to collect data on the relationship between the vehicle and the road. For example, on some non-standard roads (without a center line or lane markings), the turn signal activation can be controlled based on the relative position of the vehicle and the road. By acquiring image data and combining it with a pre-set deep learning model, the vehicle's position can be quickly determined, and then, according to the vehicle's driving rules, it can be quickly determined which side's turn signal should be activated. The deep learning model here can be implemented using existing models, which will not be elaborated on here.
[0095] Example 3:
[0096] like Figure 3 As shown, Embodiment 3 of the present invention provides an automatic turn signal control system, comprising:
[0097] The instruction acquisition module is configured to acquire the door unlocking instruction when the vehicle is in a stopped state;
[0098] The turn signal control module is configured to: control the turn signal on one side of the vehicle to illuminate and remain illuminated for a first set time according to the door unlocking command; wherein, the turn signal that should be illuminated is determined based on the relative position of the vehicle and the road.
[0099] More specifically, in the instruction acquisition module, the door unlocking instruction is an unlocking instruction issued by the car key remote control; or, the door unlocking instruction is an unlocking instruction issued by the mobile smart terminal; or, the door unlocking instruction is an automatic unlocking instruction for the vehicle to start at a set time. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.
[0100] More specifically, the turn signal control module includes:
[0101] The initial timeout is set to 10 seconds. This is understandable, as the initial timeout is set randomly by humans, based on specific big data conditions, or according to local laws and regulations. I will not elaborate further here.
[0102] Based on the relative position of the vehicle and the road, the turn signals that should be illuminated include:
[0103] When a vehicle is parked on the right side of the road in the direction of travel, the left turn signal will illuminate. For example, if a road runs east-west and the vehicle is parked on the south edge of the road with its front facing east, the left turn signal will illuminate.
[0104] When a vehicle is parked on the left side of the road in the direction of travel, the right turn signal will illuminate. For example, if a road runs east-west and the vehicle is parked on the north edge of the road with its front facing east, the right turn signal will illuminate.
[0105] When the vehicle is in motion, data on changes in steering wheel direction and angle are acquired. Specifically, steering wheel angle and direction sensors are installed at the steering column of the vehicle's steering wheel to acquire the corresponding data.
[0106] When the steering wheel is turned counterclockwise, the angle of change is greater than the first set angle, and continues for the second set time, the turn signal on the left side of the vehicle is turned on and continues for the third set time.
[0107] When the steering wheel is turned clockwise, and the angle of change is greater than the second set angle and continues for the fourth set time, the turn signal on the left side of the vehicle will be turned on and will continue for the fifth set time.
[0108] In this embodiment, preferably, the third and fifth set times are 10-15 seconds, and the second and fourth set times can be 2 seconds. It is understood that the second, third, fourth and fifth set times are set randomly by humans or according to specific big data conditions or the requirements of local laws and regulations, which will not be elaborated here.
[0109] Preferably, the first set angle and the second set angle can be 90° (assuming the ratio of the steering wheel rotation angle to the wheel rotation angle is 15:1, then the corresponding wheel steering angle is about 6°). The first set angle and the second set angle are set randomly by humans or according to specific big data conditions or according to the requirements of local laws and regulations, which will not be elaborated here.
[0110] If the counterclockwise angle change of the steering wheel (based on the steering wheel angle when the vehicle is traveling straight) gradually decreases but remains greater than the first set angle, the turn signal on the left side of the vehicle remains unchanged; if the counterclockwise angle change of the steering wheel (based on the steering wheel angle when the vehicle is traveling straight) gradually decreases until it reaches zero, the turn signal on the left side of the vehicle is turned off.
[0111] If the change in the clockwise angle of the steering wheel (based on the steering wheel angle when the vehicle is traveling straight) gradually decreases but remains greater than the second set angle, the turn signal on the right side of the vehicle will remain unchanged; if the change in the clockwise angle of the steering wheel (based on the steering wheel angle when the vehicle is traveling straight) gradually decreases until it reaches zero, the turn signal on the right side of the vehicle will be turned off.

The short-term prediction here can be implemented using neural network algorithms. For example, after making a short-term prediction, the turn signal control is performed based on the prediction results.

The first and second set angles are set randomly by humans or based on specific big data or according to the requirements of local laws and regulations, which will not be elaborated here.
[0123] In this embodiment, if the counterclockwise angle change of the steering wheel (the angle change here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases but is still greater than the first set angle, then the turn signal on the left side of the vehicle remains unchanged; if the counterclockwise angle change of the steering wheel (the angle change here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases until it becomes zero, then the turn signal on the left side of the vehicle is turned off.
[0124] In this embodiment, if the change in the clockwise direction angle of the steering wheel (the change in angle here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases but is still greater than the second set angle, then the turn signal on the right side of the vehicle remains unchanged; if the change in the clockwise direction angle of the steering wheel (the change in angle here is based on the steering wheel angle when the vehicle is driving straight) gradually decreases until it becomes zero, then the turn signal on the right side of the vehicle is turned off.

The short-term prediction here can be implemented using neural network algorithms. For example, after making a short-term prediction, the turn signal control is performed based on the prediction results.
