Abstract

The invention discloses a complete decoupling type braking system with a fail-safe function and a control method. The braking system comprises a hydraulic tank, a main cylinder, a hydraulic adjusting device and wheel cylinders. Two outlets of the hydraulic tank are communicated with two oil supply holes of the main cylinder through pipelines respectively, and two liquid discharge holes of the main cylinder are communicated with the wheel cylinders through the hydraulic adjusting device respectively; the complete decoupling type braking system with the fail-safe function further comprises a brake pedal, a brake push rod, a transmission mechanism and an external power source. The external power source is used for supplying driving torque for the transmission mechanism; one side of the brake pedal is provided with a brake pedal displacement sensor which is used for judging requirements of total braking force. On the basis that movement decoupling of the brake pedal and the brake main cylinder is achieved, the system is provided with an emergency fail-safe mechanism, and the car braking safety and reliability are effectively guaranteed while good control flexibility is achieved.

Description

technical field [0001] The invention relates to an automobile decoupling braking device, in particular to a complete decoupling braking system with failure protection and a control method. Background technique [0002] Traditional vacuum assisted braking and electric assisted braking systems use the pedal force and the boost of the power source as input forces to jointly push the brake master cylinder, and have not achieved decoupling of the brakes. This power assist system couples the pedal force to the brake master cylinder, which greatly increases the complexity of the mechanical structure. And this kind of system has a stricter control strategy for power assist. When the driver steps on the brake pedal by mistake, the pedal force will also be transmitted to the master cylinder, resulting in an obvious braking effect, but the driver has no intention of braking at this time. Contents of the invention [0003] The purpose of the present invention is to overcome the shor...
