Abstract

The invention discloses a hydraulic braking system and method, which relate to the field of automobile braking. The system includes: an oil storage tank; a decoupling pedal device connected with the oil storage tank to collect pedal braking information; a braking device connected to the storage tank The oil tank is connected to collect the oil pressure of the brake oil circuit and brake the vehicle; the controller is connected to the decoupled pedal device and the brake device to receive the pedal braking information and the oil pressure of the brake oil circuit to obtain the vehicle speed, Generate conventional braking commands; collect fault information to generate non-conventional braking commands; conventional braking power device, connected with the braking device and controller, receive conventional braking commands to control the braking device to perform conventional braking; non-conventional braking device , is connected with the brake device and the controller, and receives the unconventional brake command to control the brake device to perform unconventional brake. The invention assists the driver in emergency braking through an unconventional braking device to avoid a sudden increase in braking force when the electronic braking system fails and the pedal assist is lost.

Description

technical field [0001] The invention relates to the field of automobile braking, in particular to a hydraulic braking system and method. Background technique [0002] For the hydraulic braking system that adopts the complete decoupling of the brake pedal, there is generally a separate brake hydraulic cylinder as a backup for failure. In the event of an electronic braking system failure, pedal assist is lost and greater brake pedal effort is required to achieve the desired braking force. In an emergency situation, the sudden increase in brake pedal force is not conducive to vehicle control, and also limits the upper limit of the braking force that the driver can achieve. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a hydraulic braking system and method. When the electronic braking system fails and the pedal assist is lost, the driver is assisted in emergency ...
