Integrated electronic hydraulic brake system

Abstract

The invention discloses an integrated electronic hydraulic brake system. The system comprises a liquid storage tank, a brake master cylinder, an electric pressure buildup cylinder, a pedal feeling simulator, a hydraulic control unit and an electric control unit, wherein the liquid storage tank, the brake master cylinder, the electric pressure buildup cylinder, the pedal feeling simulator, the hydraulic control unit and the electric control unit are integrated into an integral structure; the liquid storage tank is arranged close to the brake master cylinder and is communicated with the brake master cylinder; the brake master cylinder is assembled in the hydraulic control unit; the electric control unit is arranged on the upper portion of the hydraulic control unit; the electric pressure buildup cylinder penetrates through the electric control unit and is also assembled on the upper portion of the hydraulic control unit; the pedal feeling simulator is arranged on one side of the hydraulic control unit; and the liquid storage tank is assembled on the other side of the hydraulic control unit. The brake device has the beneficial effect that enough brake pressure can be established in ashort time. And the functions of active braking, failure backup, braking energy recovery and the like are achieved.

Description

technical field [0001] The invention relates to a hydraulic braking system, in particular to an integrated electronic hydraulic braking system. Background technique [0002] At present, with the continuous development of vehicle intelligence and electrification technology, the traditional vacuum booster braking system is difficult to meet the requirements of smart vehicles and electric vehicles on the braking system. Smart cars require the brake system to have more precise brake pressure control capabilities, faster response speeds, and sufficient active braking capabilities. These conditions can be used as the underlying actuators of intelligent driving assistance systems. Electric vehicles require the braking system to have a certain decoupling capability, that is, the decoupling of the brake pedal force and the motor assist, so that the braking system can cooperate with regenerative braking, recover braking energy to the maximum extent, improve the cruising range of elect...
