Abstract

The invention discloses an electric independent steering system and a control method thereof, and belongs to the field of motor vehicle steering devices; the electric independent steering system comprises an angle sensor, a speed sensor, an inertial navigation module, an axle distance measurement module, a parking signal measurement unit, a shutdown signal measurement unit and a control unit; thespeed sensor is arranged on each driving wheel; and the inertial navigation module, the axle distance measurement module, the parking signal measurement unit, the stop signal measurement unit, the angle sensor and the control unit are arranged on a frame. According to the electric independent steering system and the control method thereof, by controlling the angles and directions of steering wheels on the left side and the right side, a chassis can be prevented from sliding and sliding on a slope; the steering accuracy of the chassis can be ensured, and the steering operation is simplified toensure that the expected heading direction of an operator is reached as soon as possible.

Description

technical field [0001] The invention discloses an electric independent steering system and a control method thereof, belonging to the field of motor vehicle steering devices. Background technique [0002] With the development of technology, electric steering gradually replaces traditional mechanical steering. At present, the commonly used electric steering system still uses a single electric motor to provide auxiliary steering force for the driver. The left and right steering wheels still adopt the Ackerman steering model in the transmission structure. This electric steering system cannot essentially solve the problem of wheel slippage on the left and right sides during steering, and in addition, it cannot meet the needs of modern complex working conditions functionally. In addition, as the working conditions become more and more diverse and the application environment is more harsh, the fixed wheelbase of the mobile platform can no longer meet the requirements of use. In...
