Abstract

The invention relates to an automobile brake simulation system. The system solves the problem in the prior art that an automatic system cannot achieve active braking and the pedal feeling cannot be adjusted. The system comprises a brake pedal and a plurality of brakes and further comprises a displacement sensor unit, a control unit, a simulation unit and an adjustment unit. The displacement sensorunit is disposed on the brake pedal and connected to the control unit, the control unit is connected to the simulation unit connected to the brakes in a control mode, and the adjustment unit is connected to the control unit. The system adopts the motor output torque to control operation of the brakes according to brake pedal displacement, and achieves the purpose of active braking of an automobile. A traditional vacuum servo system is not required, and the system is simpler in structure. The motor output torque can be adjusted through the adjustment unit to achieve adjustment of the brake pedal, and the problem that the pedal feeling of the traditional brake system is achieved by adjusting hardware parameters and cannot be changed once determined is solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile braking simulation system. Background technique [0002] In the traditional braking system, the realization of braking is through the driver applying force on the brake pedal, which is amplified and converted into hydraulic pressure by the vacuum booster system, and acts on the brake to achieve braking. Now it is used in automobiles. The vacuum booster system consists of a vacuum booster with a brake master cylinder, a vacuum tank, a vacuum pump, and a vacuum tube. The vacuum booster with a brake master cylinder utilizes the pressure difference between the vacuum and the atmosphere to apply the braking force applied by the driver to the pedals. Amplify and transmit this force to the brake master cylinder to establish hydraulic pressure, realize the conversion of pedal force to hydraulic pressure, and then achieve braking. Among them, the vacuum tank is responsi...
