Problems solved by technology

However, in essence, there are many differences in the relationship between the steering wheel angle and the steering wheel angle on different platform models. The above scheme only considers the steering wheel angle, but does not consider factors such as vehicle speed. Even if the operator just turns the steering wheel on the spot, it will cause the turn signal Open, it is obviously a defective design

Embodiment Construction

[0016] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] When the vehicle is running on the road, according to the total number of road lanes, lane types (such as one-way, multi-lane, etc.), lane direction (such as straight lanes, turning lanes, etc.), road traffic conditions (such as normal, congestion, etc.), in some cases When there is a need to change lanes, for example, when entering or exiting a ramp, when turning left at the next intersection, you need to change lanes in advance and drive on the left, or when the vehicle in front is driving too slowly and wants to change lanes and overtake, etc., turn on the turn signal in advance when changing lanes or turning.

[0018] figure 1 It shows a situation where the vehicle is turning but the turn signal may not be turned on. The figure shows a lane with lane dividing lines on both sides, and the vehicle generally...

Abstract

The invention discloses an automatic steering lamp control method. The automatic steering lamp control method comprises the following steps that in the running process of a vehicle, when a steering wheel rotates, and the rotating direction faces towards the outer side of a lane, data of the vehicle steering wheel rotation angle theta, the wheel speed v of inner side steering wheels and the distance L1 between the inner side steering wheels and a lane line at present are obtained; the lateral displacement L2 of the inner side steering wheels within a preset time duration delta t based on the steering wheel rotation angle theta and the wheel speed v is calculated; if L2>=L1, and the time duration when the steering wheel rotating direction faces towards the outer side of the lane is greater or equal to the delta t, a steering lamp is started; if L2<L1, or the time duration when the steering wheel rotating direction faces towards the outer side of the lane is less than the delta t, the steering lamp is not started. The start time of the steering lamp can be accurately judged through the automatic steering lamp control method and system.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automatic control method and system for a turn signal. Background technique [0002] In car driving technology, if the car needs to change lanes or turn when driving, the driver should turn on the turn signal in advance to remind the surrounding vehicles and pedestrians. However, in reality, it often happens that the driver forgets to turn on the turn signal, which is likely to cause traffic accidents. . At present, a solution is to monitor the steering wheel angle of the car, and use the steering wheel angle signal as a direct input. When the steering wheel angle exceeds the set value, the turn signal is automatically turned on to give a reminder to the outside world. This scheme realizes the automatic control of the turn signal to a certain extent. However, in essence, there are many differences in the relationship between the steering wheel angle and the steering wheel angle on...
