Problems solved by technology

[0003] That is to say, when an ordinary vehicle changes its driving posture, it mainly changes its posture according to the situation of the car and the direction of the road, and the adjustment of the posture is very random and not accurate enough.

Embodiment Construction

[0064] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0065] Such as Figure 1~Figure 4 As shown, a self-tuning method for a fully automatic control motor of a vehicle:

[0066] S1. Use the attitude angle sensor to measure the angle of the vehicle body, and then adjust it;

[0067] S2. It uses a two-dimensional fuzzy control algorithm to determine the rotational speed of the Mecanum wheel. The specific method is as follows:

[0068] S21, setting two input variables A, Ac and one output variable U;

[0069] Among them, A: a—the angle error of the body, the unit is °;

[0070] A is a function of the vehicle body angle error, and a is a specific function value of the function;

[0071] A c :a c —The error value of the two angles of the body, the unit is °;

[0072] A c is a function of body angle error, a c is a concrete f...

Abstract

The invention relates to a self-adjusting method for a fully automatic control motor of a vehicle. The steps are: S1, using an attitude angle sensor to measure the angle of the vehicle body; S21, setting the angle error variable A of the vehicle body as an input variable, and setting the two angles of the vehicle body The error Ac is used as another input variable, and the rotating speed U of the Mecanum wheel responsible for turning is set as the output variable; S22, determining the range of output precision; S23, setting the language value of the variable, setting A, A c , the language value of U is 7 levels; S24, fuzzy control rate is set; S25, the membership function of the definition variable seeks the membership rate of angle error and deviation; S26, calculates the final fuzzy output U*: S27, final fuzzy output Bring it into the membership function of U* to get two precise output quantities, and the final output is averaged. S3. Assign the average value to the driving system. The beneficial effect achieved by the invention is that it can turn precisely.

Description

technical field [0001] The invention relates to the technical field of vehicle direction adjustment, in particular to a self-adjustment method for a fully automatic control motor of a vehicle. Background technique [0002] When the vehicle is in motion, it is usually artificially steered. For some smart cars, according to the environmental information such as the speed of the car itself, the distance between the car and the surrounding cars, the automatic lane change of the car is realized through the set control logic. [0003] That is to say, when an ordinary vehicle changes its driving posture, it mainly changes its posture according to the situation of the vehicle and the direction of the road, and the adjustment of the posture is very random and not accurate enough. [0004] For this reason, this program designs an automatic adjustment method that manually controls the motor through Bluetooth. Although it is a manual adjustment, the specific action still depends on the...
