Embodiment Construction

[0047] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0048] The present invention is an automatic control method for vehicle curves based on driver behavior, wherein a global positioning system, a steering wheel angle sensor, a vehicle speed sensor, a control box 4 and an image acquisition device are installed on the vehicle 1, figure 1 Vehicle 1, monocular camera 2, GPS 3 and control box 4 are shown;

[0049] The vehicle 1 wherein is illustratively a family car with four wheels, and can also be other types of vehicles, such as buses or trucks; in this example, a global positioning system 3, i.e. GPS, is installed on the top of the vehicle 1, Of course, it is not limited to the top of the vehicle 1. GPS is used to collect the position data of the vehicle 1, and then obtain the lateral trajectory deviation between the ideal driver model and the ...

Abstract

The present invention is an automatic control method for vehicle curves based on driver behavior, comprising step 1, acquiring the lateral trajectory deviation between the ideal driver model and the actual driver, steering wheel angle deviation, vehicle speed deviation, Acceleration deviation; Step 2, after setting up the steering fuzzy controller, input the lateral track deviation, the rate of change of the lateral track deviation, the steering wheel angle deviation and the rate of change of the steering wheel angle deviation, and set up the braking fuzzy controller to input the vehicle speed deviation and Acceleration deviation change rate, and then respectively establish fuzzy subsets and corresponding membership functions; Step 3, get steering wheel angle adjustment and braking force adjustment after defuzzification; Step 4, steering wheel angle of steering actuator for ideal driver model The brake actuator is continuously adjusted according to the pedal force input of the brake pedal of the ideal driver model, so as to realize the automatic control of vehicle curve steering and vehicle speed.

Description

technical field [0001] The invention belongs to the field of vehicle automatic driving, in particular to an automatic control method for vehicle curves based on driver behavior. Background technique [0002] During the process of cornering, due to the limitation of the driver's vision and the interference of external thunderstorms and heavy fog, the vehicle cannot pass through the curve safely and accurately, and the complex road conditions will affect the safety of the driver's driving seat belt. There are certain hidden dangers. [0003] With the development of vehicle intelligence, self-driving vehicles are the future development trend. The driver model is based on a set path to make the vehicle move according to a given trajectory. The driver model is an important link in the development of vehicle dynamics simulation and control algorithms. With the frequent occurrence of traffic accidents, the driver model has become one of the important research topics in the curren...
