[0043] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0044] It should be noted that the directions or positional relationships indicated by "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when in use, or are the directions or positional relationships commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0045] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0046] How to control the car turn signal to make the operation more convenient? The turn signal is a reference for passive safety, and its importance is self-evident. The accuracy and stability of the turn signal directly determine the safety level of the vehicle after ESC failure and the accuracy and reliability of the automatic driving system. In addition, the turn signal is also one of the necessary sensors for many advanced assisted driving functions based on steering angle.

[0047] However, the current traditional automobile steering switch must be driven by the steering wheel in the car to drive the relevant switch return structure, and the turn signal switch is turned on and off by the return structure. The mechanical structure is complex and the operation is inconvenient. Therefore, it is very necessary to develop a more reliable and stable steering signal. This solution uses the steering wheel control angle signal combined with the switch signal to jointly determine and generate the steering control signal, which can change the steering mechanical self-locking into a steering self-reset structure.

[0048] Therefore, based on the above problems, the present invention proposes a strategy and method for turning signal to solve the problems.

[0049] (Example 1)

[0050] The present disclosure provides a method for controlling a turn signal. Figure 2 ,include:

[0051] S100: Acquire a vehicle body wheelbase and a maximum tire inward rotation angle, determine a switch steering return angle according to the vehicle body wheelbase and the maximum tire inward rotation angle; and control a turn signal according to the switch steering return angle;

[0052] S200: Determine issuing a turn signal instruction to turn on the turn signal according to a valid input signal of the steering switch, wherein the valid input signal of the steering switch is determined by the position of the steering handle in the steering gear position;

[0053] S300: Obtaining a valid signal of a lane change switch in the same direction or in the opposite direction and a steering wheel angle signal; and determining to issue a turn signal off command according to the valid signal of the lane change switch in the same direction or in the opposite direction and the steering wheel angle signal.

[0054] As a preferred technical solution of the present application, the method of obtaining the vehicle body wheelbase and the maximum tire inward rotation angle includes:

[0055] Determine a first center point between the left front wheel and the right front wheel and a second center point between the left rear wheel and the right rear wheel, and determine the vehicle body wheelbase according to the first center point and the second center point;

[0056] The maximum inward turning angle of the tire is determined by obtaining the angle at which the steering shaft controls the tire to turn toward the vehicle body.

[0057] Specifically, see Figure 3 , S1: Use the steering wheel angle signal to determine whether the current vehicle is in a lane changing state.

[0058] S2: If the vehicle is not in the process of changing lanes, then go to step S3. If the vehicle is in the process of changing lanes, then go to step S4. S3: Use the angle information of the steering wheel to obtain the current wheel angle.

[0059] S4: If the current driving direction of the vehicle is the same as or opposite to the last switched direction, then proceed to step S7. Otherwise, proceed to step S5.

[0060] S5: Records the steering wheel offset when switching the steering wheel.

[0061] S6: Divide the difference between the two recorded steering wheel offsets by the corresponding central angle to obtain the corresponding rotation amplitude A.

[0062] S7: If more than two changes of direction occur during a lane change, the distance between the two steering wheel offsets must be recalculated each time the direction changes to ensure accuracy, and then the right side and left side turn signals are controlled to turn on according to different amplitudes. If there are no multiple turns during the entire lane change, only the average value of the offset angle between the wheel direction after the first turn and the initial direction is calculated.

[0063] As a preferred technical solution of the present application, controlling the turn signal lamp according to the turn return angle of the switch includes:

[0064] Set the switch steering return angle control interval to the first preset interval,

[0065] The first preset interval range is greater than minus 10 degrees and less than 10 degrees.

[0066] As a preferred technical solution of the present application, controlling the turn signal lamp according to the turn return angle of the switch includes:

[0067] When the switch steering return angle α does not fall within the first preset interval, it is determined that the left and right turn signals are valid, and a valid signal is sent to control the left and right turn lights to turn on;

[0068] When the switch steering return angle α falls into a first preset interval, it is determined that the left and right turn signals are invalid, and an invalid signal is sent to control the left and right turn lights to be turned off.

[0069] As a preferred technical solution of the present application, controlling the turn signal lamp according to the turn return angle of the switch includes:

[0070] When the switch steering return angle α is greater than zero, the left turn signal is controlled, and when the switch steering return angle α is less than zero, the right turn signal is controlled.

[0071] As a preferred technical solution of the present application, the control of the turn signal lamp according to the turn return angle of the switch also includes:

[0072] When the switch steering return angle α does not fall within the first preset interval and is greater than zero, it is determined that the left turn signal is valid, and a left turn valid signal is sent to control the left turn lamp to turn on;

[0073] When the switch steering return angle α does not fall within the first preset interval and is less than zero, it is determined that the right turn signal is valid, and a right turn valid signal is sent to control the right turn lamp to turn on.

[0074] As a preferred technical solution of the present application, the control of the turn signal lamp according to the turn return angle of the switch also includes:

[0075] When the switch steering return angle α falls into a first preset interval and is greater than zero, it is determined that the left turn signal is invalid, and a left turn invalid signal is sent to control the left turn lamp to be turned off;

[0076] When the switch steering return angle α falls into the first preset interval and is less than zero, it is determined that the right turn signal is invalid, and a right turn invalid signal is sent to control the right turn lamp to be turned off.

[0077] Specifically, see Figure 3 When the switch steering return angle α does not fall into the first preset interval, the left and right turn signals are valid, and the left and right turn lights are controlled to be turned on; when the switch steering return angle α falls into the first preset interval, the left and right turn signals are invalid, and the left and right turn lights are controlled to be turned off. In specific implementation, the domain controller determines whether the switch steering return angle α does not fall into the first preset interval to control the left and right turn lights to be turned on.

[0078] For example, the turn signal is turned on under the following conditions: a. When the steering handle of the combination switch is operated to the steering gear position, the domain controller receives a valid signal from the steering switch input; b. The domain controller receives a valid signal from the lane change switch in the same direction or the opposite direction again; c. After the domain controller receives a steering wheel angle signal that is greater than the steering return angle α in the direction of the activated side turn signal, it returns to within 10°.

[0079] In some embodiments, the switch steering return angle α is controlled by the steering switch handle, and there are five gears, namely left turn, left lane change, zero position (no function), right turn, and right lane change. The switch signal is connected to the domain controller through a wiring harness.

[0080] In some other embodiments, the switch steering return angle α is detected by an electronic steering column, and the signal can change with the rotation of the steering wheel, reflecting the rotation angle information of the steering wheel in real time.

[0081] The working process of the turn signal control method in the present disclosure is described in detail below.

[0082] The present application provides a method for controlling a turn signal, the basic idea of ​​which is to realize the switching of the turn signal through a combination switch + logic control scheme, so that the driver can quickly and accurately switch the corresponding position in the combination switch to the corresponding state during driving, thereby effectively improving the safety of the vehicle during driving.

[0083] The specific implementation process and methods are as follows:

[0084] 1. Define the steering return angle - that is, when the driver releases the steering wheel, the steering wheel will return to the initial position. The setting of this initial position needs to meet the following conditions:

[0085] (1) Vehicle wheelbase H, (2) Total number of steering wheel rotations 2.5R, (3) Maximum tire inward rotation angle 30°;

[0086] (4) Switch return angle α = (arcsin(H / 30) / 30°)*1.25*360 / 2.

[0087] Specifically, after the specific value of the vehicle wheelbase H is measured by the control system on the vehicle, it is substituted into the formula of the switch steering return angle α = (arcsin(H / 30) / 30°)*1.25*360 / 2, and the corresponding steering return angle α is obtained and then an interval judgment is made.

[0088] 2. Turn on the turn signal through the following conditions: a. When the steering handle of the combination switch is operated to the steering gear position, the domain controller receives a valid signal from the steering switch input; b. The domain controller receives a valid signal from the lane change switch in the same direction or opposite direction again; c. After the domain controller receives the steering wheel angle signal in the direction of the activated side turn signal that is greater than the steering return angle α, it returns to within 10°.

[0089] 3. Turn off the turn signal under the following conditions: a. The domain controller receives a valid signal from the lane change switch in the same or opposite direction again; b. The domain controller receives a steering wheel angle signal that is less than 10° in the direction of the activated turn signal. 4. All other conditions are normal.

[0090] The switch steering return angle α=(arcsin(H / 30) / 30°)*1.25*360 / 2, where H is the vehicle wheelbase. Specifically, the steering return angle is defined as follows: vehicle wheelbase H, total number of steering wheel rotations 2.5R, maximum tire inward rotation angle 30°, switch steering return angle α=(arcsin(H / 30) / 30°)*1.25*360 / 2.

[0091] Specifically, the first preset interval is greater than -10° and less than 10°. For example, when the angle of the switch steering return angle α is obtained to change from 10 degrees to 0 degrees, it means that at this time, the steering wheel is returning to the center, and at this time, the left lane change signal light is turned off. When the angle of the switch steering return angle α is obtained to change from -10 degrees to 0 degrees, it means that at this time, the steering wheel is returning to the center, and at this time, the right lane change signal light is turned off.

[0092] Specifically, the left and right turn signals include a left lane change signal light and a right lane change signal light; when the switch steering return angle α is greater than zero, the left lane change signal light is controlled, and when the switch steering return angle α is less than zero, the right lane change signal light is controlled.

[0093] Specifically, obtaining the switch steering return angle α includes:

[0094] The electronic steering column detects the switch steering return angle α.

[0095] Specifically, controlling the left and right turn signals to turn on or off includes:

[0096] The domain controller is electrically connected to the electronic steering column and the left and right turn signals. The domain controller obtains the switch steering return angle α. When the switch steering return angle α does not fall within the first preset interval, the left and right turn signals are controlled to turn on.

[0097] When the switch steering return angle α falls into the first preset interval, the left and right turn lights are controlled to be turned off.

[0098] Specifically, the domain controller is electrically connected to the electronic steering column and the left and right turn signals, receives the combined switch signal of the left and right turn signals through the wiring harness, receives the steering wheel angle signal through the CAN bus, and performs logical judgment. Furthermore, the domain controller controls the activation and deactivation of the external turn signals.

[0099] Specifically, the first preset interval also includes a lane change interval; when the switch steering return angle α does not fall into the lane change interval, the left and right turn signals are controlled to turn on. Specifically, the lane change interval is -5 degrees to 5 degrees. When the switch steering return angle α is 8 degrees or -8 degrees, the switch steering return angle α does not fall into the lane change interval, that is, the steering wheel steering angle is sufficient to change lanes, but does not meet the steering requirements, and the left and right turn signals are turned on. When the switch steering return angle α is 3 degrees or -3 degrees, the switch steering return angle α falls into the lane change interval, that is, the steering wheel steering angle is insufficient to change lanes, and does not meet the steering requirements, and the left and right turn signals are turned off.

[0100] (Example 2)

[0101] Furthermore, a vehicle steering signal control system for executing the above method includes a chassis system located in a car compartment, a transmission and a clutch for controlling the driving state of the car, and a vehicle speed sensor for detecting the running speed of the car are arranged at the front end of the chassis system, wherein an electronic instrument panel for controlling the direction and transmitting wheel rotation information, which integrates the steering system and the power transmission system, is also installed above the chassis system, and a battery pack is installed at the rear of the chassis system. The chassis system also includes a steering mechanism installed under the seat, and a motor drive assembly is also arranged below the steering mechanism, and a brake pedal is installed on one side of the motor drive assembly, and fixed brackets for limiting the axial movement of the steering wheel are respectively installed below the brake pedal, and at the same time, multiple support leg blocks are symmetrically placed on both sides of the limited steering wheel, and each steering wheel has a slidably connected steering wheel seat at the periphery. It is further preferred that a first spring link and a second spring link are respectively installed at both ends of the bottom of the rotating wheel seat, a retractable stud bolt is sleeved between the lower parts of the first spring link and the second spring link, and the top of the stud bolt passes through the side of the side walls of the two steering wheels close to each other in sequence and is positioned above the two steering wheels through the first nut and the second nut.

[0102] (Example 3)

[0103] Further, see Figure 1 The complete process of changing lanes by rotating the steering wheel is to first press the lane change switch, then hold down the button until you move to the direction you want to move to, and finally release the button to return to the starting point. During this process, the driver will always stare at the direction mark on the dashboard. It takes a total of three steering wheel turns from the start to the end of the turn to complete this action.

[0104] First of all, in the first round, we just need to let the driver feel that he is going to the left. In the second round, we need to let him feel that the front of the car has reached the desired location and there is an obvious deceleration phenomenon to meet the requirements. The third round is more important for those who like fast-paced life because they may have to choose to change gears and step on the accelerator immediately due to some emergency situations. Although this practice can help them improve their reaction speed, it also increases their risk factor in driving, so we must try to avoid this situation from happening around us.

[0105] Furthermore, the present invention also provides a solution with the following implementation approach: its main principle is to determine whether there are obstacles in front of the vehicle and the road conditions, etc. by detecting the image data output by four cameras in front, behind, left and right of the vehicle and combining it with the road map information and vehicle speed information provided by the on-board navigation system.

[0106] These situations are caused by the user's own reasons, so before taking corresponding measures, a series of complex processing steps are required, such as analyzing the resolution and contrast of the image data, so as to avoid problems that do not need to be concerned about.

[0107] For example, problems such as water accumulation on rainy days causing the camera to not work properly, or insufficient light at night causing the captured image to be blurry or even nothing can be seen at all can be ruled out.

[0108] It is also worth mentioning that the system also includes a GPS positioning module to track the vehicle's route and sense the vehicle's status through a gyroscope sensor, thereby sending out warning signals in a timely manner to remind the owner to pay attention to safety. In addition, there is a set of monitoring equipment specifically for pedestrian safety called a radar detector. It is composed of multiple transmitting antennas and the computer program automatically manages the working frequency of each antenna. At the same time, it can track the other party's movement trajectory to identify it with high precision and take relevant protective measures according to the specific situation. For example, when someone is found approaching the car, an alarm bell will be triggered immediately and a red warning symbol will be displayed to remind others around to stay away from this place to avoid unnecessary trouble.

[0109] (Example 4)

[0110] Another implementation method provided by the present invention is that when in use, the mobile phone can be placed on the wireless charging pad in the car to replenish the battery. However, it should be noted that this design does not mean that all models can support this function because some models do not have this feature. Therefore, we recommend purchasing products with such configurations to better play their respective advantages. In addition, it should be pointed out that most of the smart phones on the market simply expose the charging port to the outside without considering how to hide the wires. Therefore, it is still necessary to pay attention to the details in this regard during use, especially when traveling for a long time, because once there is a power outage or leakage, it will bring very serious safety hazards and may even cause fire accidents that affect people's daily life and work order.

[0111] Another solution of the implementation method proposed by the present invention: This solution is an improvement on the existing technology in that: after studying the existing technology, it is found that many car companies are now trying to launch the automatic steering technology, but due to the limited life of traditional mechanical parking brakes, coupled with factors such as high costs and complex installation locations, the final results are often unsatisfactory. Therefore, during development, it is necessary to invest a large amount of additional funds to carry out research and development experiments and other work. Of course, the core is to continuously optimize and adjust the degree of coordination between various components on the basis of maintaining the original performance, so as to ensure that the entire project is smoothly promoted and the expected benefits are maximized. At the same time, in the subsequent production and manufacturing stages, it is also necessary to pay attention to the quality control link to ensure that each finished product can meet the qualified standards, and it is best to regularly organize professionals to conduct inspections and tests and promptly feedback relevant information to relevant departments so as to promptly discover and solve problems.

[0112] In summary, the control method of the steering signal of the automatic vehicle control based on the electronic shift lever provided by the present invention can solve various defects existing in the current market and greatly improve work efficiency and reduce the waste of manpower and material resources. It realizes the switching of the steering signal through the combination switch + logic control scheme, so that the driver can quickly and accurately switch the corresponding position in the combination switch to the corresponding state during driving, thereby effectively improving the safety of the vehicle during driving.
