Abstract

An automobile steering control system and a control method for the system relate to the technical field of automobile steering control. The utility model aims to solve the problem that the existing steering control system and control method of the automobile are not conducive to indicating the steering of the automobile. Both the left turn signal group and the right turn signal group are composed of N turn signal lights. When the steering lever is moved, the steering control circuit controls the turn signal lights of the corresponding turn signal group to light up. The turn signal lights in turn from left to right indicate that the car is turning right. Steering, turning on from right to left means that the car is turning left. It is more intuitive and faster to judge the direction of steering according to the order of the turn lights in the turn signal group, and it is only based on a set of turn signal groups that are turned on. Determine whether the car is turning and the direction of turning. The invention can be used to control the indicator light in the steering of the automobile.

Description

Automobile steering control system and control method of the system

technical field

The invention relates to the technical field of automobile steering control.

Background technique

The control method of the traditional car turn signal is that when the car steering lever is moved, the car turn signal will light up, one on each side of the turn signal. For the rear car, since the left and right turn signals are the same, the prompt effect to the driver of the rear car is not very intuitive when the turn signal is on. When the human eyes see the turn signal is on, the brain needs a reaction time to judge that the front car is about In which direction to turn, especially in the case of congested roads, it is easy to cause the driver behind to be in a hurry and cause a traffic accident.

Contents of the invention

The invention aims to solve the problem that the existing automobile steering control system and method are not conducive to instructing automobile steering, thereby providing the automobile steering control system and method.

The automobile steering control system of the present invention comprises a steering control circuit and two turn signal groups, left and right; the two turn signal groups are composed of N turn signal lights, N is an integer greater than 1, and two The turn signals of the turn signal group are arranged in a "one" shape;

The 2N control signal output terminals of the steering control circuit are respectively connected to the control signal input terminals of a total of 2N turn signal lights of the two turn signal groups; The turn signals light up sequentially in the direction of turn.

The above-mentioned N is 3 or more.

A control method for an automobile steering control system, the method is:

When the steering lever of the automobile is in motion, the steering control circuit controls the N turn lights of the corresponding turn signal group to light up in sequence along the steering direction.

The N turning lights of the above-mentioned left turn signal group are respectively the No. 1 left turn signal to the N number left turn signal, and the No. 1 left turn signal to the N number left turn signal are arranged in sequence from right to left; the N number of right turn signal groups The turn signals are No. 1 right turn signal to N No. right turn signal, and the No. 1 right turn signal to N right turn signal are arranged in order from left to right;

When the steering lever of the car is moved downward, the No. 1 left turn signal of the left turn signal group lights up. After t time, the No. 2 left turn signal light of the left turn signal group lights up. After t time, the No. 3 left turn signal group of the left turn signal group lights up. The left turn signal light is on until all the N turn signal lights of the left turn signal group light up, and then after t time, all the N turn signal lights of the left turn signal group go out. Loop until the car steering rod returns to its original position; t>0;

When the steering lever of the car is moved upwards, the No. 1 right turn signal of the right turn signal group lights up. After t time, the No. 2 right turn signal light of the right turn signal group lights up. The turn signals are turned on until all the N turn signals of the right turn signal group light up, and then after t time, all the N turn signals of the right turn signal group go out, so far it is a cycle, and the right turn signal group cycles according to this cycle , until the car steering lever returns to its original position.

The range of the above t is 0.7s-1s.

In the automobile steering control system according to the present invention, when the automobile steering lever is moved downward, the steering control circuit controls the turn lights of the left turn signal group to light up sequentially from right to left; The turn signals of the light groups light up sequentially from left to right. Even if the rear car or pedestrian cannot see the two sets of turn signal lights at the same time, they can judge the direction of the car’s turn based on the set of light turn signal groups. Turning on from left to right means that the car is turning right, and turning on from right to left means that the car is turning left. In the existing steering control system, when the steering lever of the car is turned, only the left turn signal or the right turn signal lights up, but the control system of the present invention can make the following driver change the direction according to the order in which the turn signal lights in the turn signal group are turned on. Intuitively and quickly judge the steering of the car, and the effect of prompting the driver behind is better.
