Problems solved by technology

However, the traditional electric steering system has the following problems: high assembly cost, as high as 1000-2000 yuan; high maintenance cost; many parts, complicated data transmission; constant minimum turning radius, which is not conducive to the different requirements of turning radius differences in different working conditions (such as vehicle speed High, hope the steering is not so sensitive, low speed, hope the steering is sensitive)
[0003] Therefore, there is an urgent need for a vehicle steering strategy to solve the problem of complex data transmission in traditional steering systems

Abstract

The invention discloses an automobile steering control method and device, terminal equipment and a storage medium, rolling radius data and rotation angle data are obtained through collected automobile data, an angular velocity difference value is obtained through calculation, and finally, the angular velocity difference value is superposed on an outer side tire according to a steering instruction, so that an inner wheel and an outer wheel form a speed difference, and the steering accuracy of an automobile is improved. Therefore, automobile turning is achieved. Through calculation of the angular velocity difference value, the data transmission efficiency of steering control is improved, and optimization of the control logic of an automobile and construction of the development direction of an intelligent automobile are facilitated.

Description

technical field [0001] The invention relates to the field of new energy vehicle products, in particular to a control method, device, terminal equipment and storage medium for vehicle steering. Background technique [0002] The traditional electric steering system used in automobiles is mainly composed of a steering gear, a steering transmission shaft, an EPS controller (ECU), a steering column and a steering wheel. The EPS controller provides steering assistance to the driver according to the vehicle speed, steering wheel angle and other signals according to the calibrated current curve. However, the traditional electric steering system has the following problems: high assembly cost, the cost is as high as 1000-2000 yuan; high maintenance cost; many parts and complex data transmission; the minimum turning radius is constant, which is not conducive to the different requirements of turning radius in different working conditions (such as vehicle speed) High, I want the steerin...
