Electric vehicle shift-by-wire control system and control method thereof

Abstract

The invention provides an electric vehicle shift-by-wire control system. The control system comprises an ATM control module, a steering signal module, a gear shifting signal module, a speed changing box module, a main drive motor module and a main drive motor controller module. The signal output end of the steering signal module, the signal output end of the gear shifting signal module and the signal output end of the speed changing box module are connected with the signal input end of the ATM control module. The signal output end of the ATM control module is connected with the main drive motor module through the main drive motor controller module. The smoothness of steering switching is improved. A gear shifting switch is continuously and rapidly shifted, a gear shifting motor does not respond, and the misoperation of a driver is avoided. The counter potential impact of the gear shifting motor is reduced, the electromagnetism abrasion of the motor is greatly reduced, and the service life of the motor is prolonged.

Description

Technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a wire-controlled shift control system for electric vehicles. Background technique [0002] The wire control technology originated from the aircraft control system. The aircraft's new flight control system converts the pilot's control commands into electrical signals, and uses the computer to control the flight of the aircraft. This kind of control method is introduced to car driving, which is to convert the driver's operation into an electric signal through the sensor, which is transmitted to the power amplifier through the electric signal network and then pushes the actuator. With the continuous deepening of automobile electronics, wire-control technology will be widely used in automobiles. The bulky and low-precision mechanical system will be replaced by accurate and sensitive electronic sensors and actuators. The traditional automobile control mechanism and control metho...

Problems solved by technology

The drive-by-wire technology is the driving computer that actively adjusts and controls steering, acceleration and other behaviors. Although the drive-by-wire technology has been continuously developed for many years, consumers still think that the drive-by-wire technology is immature and not as reliable as mechanical transmission. I feel that the use of the wire control system is not as good as the traditional mechanical system, so the popularization of this technology has been greatly hindered
