Abstract

The invention relates to a hybrid dual-loop brake system with various working modes, and a brake method. The hybrid dual-loop brake system comprises a manual brake loop and a brake-by-wire loop; the manual brake loop comprises a manual cylinder connected with a brake pedal, the manual cylinder is connected with a second electric cylinder through a brake pipeline, and the second electric cylinder is electrically connected with a brake controller and connected with a first brake set through a brake pipeline; and the brake-by-wire loop comprises a first electric cylinder connected with a second brake set, the brake controller connected with the first electric cylinder is connected with a pedal travel sensor, and the pedal travel sensor is connected with the manual cylinder. The hybrid dual-loop brake system and the brake method have the advantages that brake response is quick, the brake pedal sensing and brake direction stability is good, and the ground adhesion utilization rate is high;the system is simple in structure and low in cost; and the reliability is high, and the failure protection capacity is high.

Description

technical field [0001] The invention belongs to the technical field of automobile brake systems, in particular, it is a hybrid dual-circuit brake system with multiple working modes including a manual brake circuit and a wire-controlled brake circuit. Background technique [0002] According to the division of the International Society of Automotive Engineers, intelligent driving vehicles are divided into five levels, namely, driver assistance (level 1), partial automation (level 2), conditional automation (level 3), high automation (level 4) and full automation (level 4). Level 5). As far as braking systems are concerned, all levels of intelligent driving require the car to have autonomous braking, which applies the brakes to all or some of the wheels without the driver engaging the brake controls. At present, the devices that can implement autonomous braking mainly include electro-hydraulic braking (EHB), electro-mechanical braking (EMB), hydraulic control unit of electroni...
