Abstract

The invention provides a vehicle braking and steering combined system comprising an inflator (10), a motor (20), a steering oil pump (30), a controller (40), a gas tank (60) and a steering gear (70); the motor drives the steering oil pump, and an electromagnetic clutch drives the inflator; the gas tank is provided with a pressure sensor; the steering gear is provided with a rotary angle transmitter; the gas tank is provided with the highest air pressure value, the secondary high air pressure value, and the lowest air pressure value; the controller controls the electromagnetic clutch to connect or disconnect according to a steering signal detected by the rotary angle transmitter and the air pressure value collected by the pressure sensor; the whole combined system is simple and compact in structure; the inflator is convenient in start-stop control; bad influences, caused by the working inflator, on the steering gear steering operation can be substantially reduced.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a combination system of braking and steering of a vehicle. Background technique [0002] In existing vehicles, especially electric vehicles, two motors are used to drive the air compressor and the steering oil pump respectively. The air compressor is used to provide air pressure for the vehicle braking system, and the steering oil pump provides power for the vehicle steering system. . In this way, more layout space on the chassis will be occupied, and the weight of the whole vehicle and the manufacturing cost will also be increased. If a motor is used to drive the air compressor and the steering oil pump at the same time, it will bring about related problems in control. Contents of the invention [0003] The purpose of the present invention is to provide a combination system of vehicle braking and steering, which can simultaneously drive an air compressor and a steering oil pump throu...
