Problems solved by technology

Among them, the master cylinder piston is connected with a signal transmitter that moves linearly with it, and the sensor obtains the displacement information of the master cylinder piston by detecting the linear motion of the signal transmitter, but the detection accuracy of this method is low, for example, when the master cylinder piston displacement When it is small, the displacement of the signal transmitter is also small, and the sensor cannot detect the linear motion of the signal transmitter, so that the displacement information of the master cylinder piston cannot be detected, and the anti-interference ability of the signal output is poor

Abstract

The invention discloses a hydraulic device for a brake system, the brake system and a vehicle. The hydraulic device for the brake system comprises an oil path block, a main cylinder piston arranged on the oil path block in a linear motion mode, a signal transmitter, a motion conversion mechanism and an angle sensor, wherein the signal transmitter is arranged on the oil path block and connected with the main cylinder piston, and the signal transmitter moves linearly along with the main cylinder piston; the motion conversion mechanism is arranged on the oil path block and is in transmission connection with the signal transmitter, and the motion conversion mechanism converts linear motion of the signal transmitter into rotation motion of the motion conversion mechanism; and the angle sensor is used for detecting the rotation angle of the motion conversion mechanism and generating an electric signal of the displacement information of the main cylinder piston. The hydraulic device for the brake system is high in active piston displacement information detection precision, stable in signal output, high in anti-jamming capability and the like.

Description

Technical field[0001]The present invention relates to the field of vehicle technology, and more particularly to a hydraulic device for a brake system, a brake system having the hydraulic device for a brake system and a vehicle having the brake system.Background technique[0002]Vehicles in the related art typically have a sensor for detecting the main cylinder piston displacement information, thereby enabling the electronic control unit (ECU) to determine the working condition of the vehicle according to the information. However, the master cylinder piston is connected to a signal transmitter with its linear motion, the sensor acquires the displacement information of the master cylinder piston by detecting the linear motion of the signal transmitter, but the detection accuracy of this mode is low, for example, when the master cylinder piston displacement When the signal transmitter is smaller, the sensor cannot detect the linear motion of the signal transmitter, so that the displaceme...
