Abstract

The invention provides a compound EPS control system and method used for a distributed driving electric automobile. The compound EPS control system comprises a steering disc, an input shaft, a torqueand angle sensor, a steering wheel assisted motor, a clutch and speed reduction mechanism, a steering output shaft, a steering gear, a rack, a steering track rod, steering wheels, an ECU, a rear wheelangle sensor, a steering motor, a worm and gear, a rear wheel steering rack, a rear wheel steering rack, a rear wheel steering track rod and rear wheels. By means of the compound EPS control system and method used for the distributed driving electric automobile, the four-wheel independent driving electric automobile has high handling stability of a four-wheel steering wheel while bringing EPS advantages into play and has the advantages of being safety in driving, environmentally friendly, high in reliability, short in driving transmission chain, efficient in transmission and compact in structure and saving energy.

Description

technical field [0001] The invention relates to the technical field of automobile steering control, in particular to a composite EPS control system and method for distributed drive electric vehicles. Background technique [0002] With the continuous innovation of automobile production and sales, the problems of energy shortage and environmental pollution are becoming more and more serious. In order to cope with the dual pressures of global energy and the environment, it has become a priority to develop energy-saving, environmentally friendly, safe and efficient new energy vehicles and their core component systems. Difficult issues that governments and the automotive industry must address. Electric Power Steering System (EPS for short) is a power steering system that directly provides auxiliary steering torque from a motor. It combines the latest power electronics technology and high-performance motor control technology to significantly improve the vehicle's static performanc...
