Brake system abs road sense compensation and stroke simulation coupling control device and method

Abstract

The invention discloses a brake system ABS road sense compensation and stroke simulation coupling control device and method, the device includes a wheel, an EMB system, a CAN bus, an ABS road sense and stroke simulation coupling controller, a first high-speed switch valve, a second High-speed switching valve, oil pump, oil tank, brake pedal, input push rod, force sensor and brake master cylinder; the wheels are connected to the EMB system, the EMB system is electrically connected to the CAN bus, and the CAN bus is coupled with ABS road sense and stroke simulation The controller is electrically connected; the ABS road sense and stroke analog coupling controller are respectively electrically connected to the first high-speed on-off valve, the second high-speed on-off valve and the motor. The present invention has simple structure and low cost, and uses the ABS road sense and stroke simulation coupling controller to intervene on the first high-speed on-off valve, the second high-speed on-off valve and the motor, and can take into account the ABS road sense under the premise of realizing the pedal stroke simulation , significantly improve the braking quality of the brake-by-wire system.

Description

technical field [0001] The invention relates to a braking system ABS road sense compensation and stroke simulation coupling control device and method. Background technique [0002] The development of the new four modernizations of today's automobiles—electrification, intelligence, networking, and sharing—puts forward many new demands on automobile braking systems. Traditional braking systems have been difficult to meet, and a new type of brake-by-wire system has emerged as the times require. . The brake-by-wire system is an advanced electronically controlled new automobile braking system. It is composed of a built-in pedal displacement sensor, a pedal feeling simulator, a motor, a reduction transmission mechanism, a brake master cylinder, a housing, and a controller. The traditional vacuum booster brake system is a purely mechanical brake system that relies on vacuum to achieve boost, while the wire-controlled electronic hydraulic brake system uses the motor as the power s...
