Problems solved by technology

[0009] However, in the above two methods, all are carried out after the front wheels have been turned, so they are not the dominant way to produce vehicle steering, but are all used to eliminate the torque generated by the vehicle in the vertical direction by assisting the steering. To keep the car stable, it does not change the front wheel steering mechanism of the traditional car, so there are still disadvantages of mechanical components

Abstract

A steering system for electric car is composed of a direction indication unit for generating the direction signal, an information acquisition unit for acquiring the state values of car and converting them to electric signals, a processing-operating unit for operating said two kinds of electric signal to obtain the steering control instructions for each wheel, and a control executing unit for performing actual steering operation according to said steering control instructions.

Description

【Technical field】 [0001] The invention relates to an electric vehicle steering system, in particular to an electric vehicle steering system which applies electronic control, drives or brakes each wheel separately, and realizes vehicle steering through wheel speed difference. The present invention also relates to a steering method for an electric vehicle implemented by the above system. 【Background technique】 [0002] The development of automobile technology is changing with each passing day. With the integration of electronic technology, especially IC chips, more and more powerful functions, automobile design has gradually begun to move towards the direction of electronization. The large number of mechanized components in traditional automobiles have been gradually replaced by electronic devices. . In the fields of power transmission assembly, chassis control, body control, and information and communication of automobiles, automotive electronics have been widely used. Compa...
