Description

Technical Field

[0001] The present invention relates to the technical field of vehicle control, and in particular, to a method, device, and equipment for automatically resetting the indication of a turn signal of an electric two-wheeler. Background Art

[0002] The turn signal control of traditional electric two-wheelers relies on manual activation and reset by the driver, which has potential safety hazards: the driver may forget to turn off the turn signal, resulting in misjudgment of the driving intention by the following vehicles. The operation is cumbersome: frequent manual reset distracts the driver's attention, especially increasing the risk in complex road conditions. The deficiencies of existing automatic activation and reset solutions: some vehicles use timed shutdown or pre-judgment algorithms, but they cannot accurately determine the end state of a turn (such as misresetting when the turn is not completed, or continuous activation in a curve causing confusion). Therefore, there is an urgent need for a control method that can real-time sense the vehicle dynamics, intelligently judge the turning state, and automatically reset. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a method, device, and equipment for automatically resetting the indication of a turn signal of an electric two-wheeler to overcome the problems existing in the current prior art.

[0038] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope protected by the present invention.

[0039] Figure 1 It is a flowchart provided by an embodiment of a method for automatically resetting the indication of a turn signal of an electric two-wheeler of the present invention. Please refer to Figure 1 , and this embodiment may include the following steps:

[0040] S1. Real-time detect the turn signal switch signal, and when the turn signal on signal is detected, turn on the automatic reset function of the turn signal indication;

[0041] S2. Obtain the steering data of the current electric two-wheeler;

[0042] S3. When the steering data meets a preset threshold and after a preset time, automatically turn off the turned-on turn signal and turn off the automatic reset function of the turn signal indication.

[0043] It can be understood that in this embodiment, first, the turn signal switch signal is detected in real time, and when the turn signal on signal is detected, the automatic reset function of the turn signal indication is turned on. Then, the steering data of the current electric two-wheeler is obtained. Finally, when the steering data meets a preset threshold and after a preset time, the turned-on turn signal is automatically turned off and the automatic reset function of the turn signal indication is turned off. In this embodiment, after the turn signal is turned on, by judging the steering data of the current electric two-wheeler, it is determined whether the current electric two-wheeler has completed a turn, and the turned-on turn signal is automatically turned off after the turn is completed, thus solving the problem in the prior art that the end state of a turn cannot be accurately judged.

[0044] Preferably, step S2 includes:

[0045] Obtain the steering data of the current electric two-wheeler, and perform filtering processing on the steering data through a filtering algorithm.

[0046] It can be understood that in order to eliminate the influence caused by road surface bumps, the road surface bump noise is eliminated by setting a filtering algorithm. For example, low-pass filtering is used to process the gyroscope data.

[0047] Preferably, the steering data includes: the body tilt angle, the handlebar return rate, the vehicle speed, the vehicle lateral acceleration, and the driving trajectory curvature.

[0048] It can be understood that the body tilt angle and angular velocity are detected in real time through an angular velocity sensor (gyroscope with accelerometer). The accelerometer can collect lateral / longitudinal acceleration to assist in judging the steering state. Through the steering angle sensor, the steering angle of the handlebar and the rate of returning to the straight position are monitored. Through GPS (speed sensor), the vehicle speed and the curvature of the driving trajectory are obtained.

[0049] Preferably, step S3 includes:

[0050] When the body tilt angle is less than the first preset threshold, the rate of the handlebar returning to the straight position reaches the second preset threshold, the vehicle speed is stable at the third preset threshold, the lateral acceleration of the vehicle is less than the fourth preset threshold, and the curvature of the driving trajectory is less than the fifth preset threshold, it is determined that the current electric two-wheeler has entered a straight road;

[0051] After a preset time, the already turned-on turn signal is automatically turned off, and the automatic reset function of the turn signal indication is turned off.

[0052] It can be understood that when the turn signal switch is activated, the ECU central control receives a signal to turn on the turn signal device; at the same time, it monitors according to the sensor components: the body tilt angle gradually decreases from 15° to 3°; the steering angle returns at a rate of 0.8 rad / s; the vehicle speed is stable at 20 km / h and the lateral acceleration < 0.2 m / s 2 ; GPS shows that the vehicle enters a straight road (radius of curvature > 50 meters); after the above state lasts for 2 seconds, the ECU central control obtains the vehicle dynamic data in real time through multi-sensor fusion; based on the comprehensive judgment of the tilt angle, steering angle, acceleration, and trajectory curvature, it is determined whether the conditions meet the threshold setting requirements; if they meet, a turn signal off signal is generated, the already turned-on turn signal is automatically turned off, and the automatic reset function of the turn signal indication is turned off.

[0053] Preferably, when the automatic reset function of the turn signal indication is turned on, it further includes:

[0054] Detect whether the vehicle speed of the current electric two-wheeler exceeds the preset vehicle speed;

[0055] If so, turn on the automatic reset function of the turn signal indication;

[0056] If not, the automatic reset function of the turn signal indication is prohibited from being turned on.

[0057] It can be understood that when the automatic reset function of the turn signal indication is turned on, by judging the current vehicle speed, for example: vehicle speed < 5 km / h; it is determined that the current electric two-wheeler is in a low-speed or stationary state, and at this time, the automatic reset function is disabled to prevent mis-triggering.

[0058] Preferably, it further includes:

[0059] Before the automatic reset function of the turn signal indication automatically turns off the already turned-on turn signal, if a turn signal off signal or a secondary turn signal turn-on signal is detected, the automatic reset function of the turn signal indication is turned off.

[0060] It can be understood that when it is detected that the driver manually turns off or performs a secondary turning operation, the automatic reset process is immediately interrupted. By adding a manual operation priority logic, the impact of the automatic reset function of the turn signal indication on the driver is avoided.

[0061] The present invention also provides a control device for automatically resetting the turn signal indication of an electric two-wheeler, which is used to implement the above method embodiments.

[0063] The sensor module 3 is used to obtain the steering data of the current electric two-wheeler;

[0064] The ECU central control 2 is also used to automatically turn off the already turned-on turn signal and turn off the automatic reset function of the turn signal indication when the steering data meets a preset threshold and after a preset time.

[0065] Preferably, the sensor module 3 includes:

[0066] An angular velocity sensor, which is used to obtain the body tilt angle and the vehicle lateral acceleration;

[0067] A steering angle sensor, which is used to obtain the handlebar return rate;
