Abstract

The invention discloses an integrated electronic hydraulic brake system of an automobile. The integrated electronic hydraulic brake system comprises a brake master cylinder output unit with an oil storage cup, a hydraulic control unit (HCU), an electronic control unit (ECU) and a wheel brake. The integrated electronic hydraulic brake system has the advantages that a conventional brake condition and an ABS (anti-lock braking system) brake condition can be implemented, a power supply failure protection function can be realized when the ECU is powered down, in other words, normal braking can be guaranteed even when the system is in power supply failure, and the stability of the system is improved on the basis that brake functions are completed; various intelligent automobile auxiliary systems relevant to the brake system can be implemented by the aid of the hydraulic control unit (HCU).

Description

technical field [0001] The invention relates to a brake system, in particular to an automobile integrated electronic hydraulic brake system. Background technique [0002] Automobile braking system is an important component to ensure the safety of automobiles. With the development of automobile technology, the traditional vacuum booster system will make the structure more complicated, the cost is higher, and the volume is larger. Therefore, it becomes a trend to replace the vacuum booster system with other structures. The automobile integrated electro-hydraulic braking system proposed by the present invention uses an output unit of a brake master cylinder with an oil storage cup to replace a serial vacuum booster, and proposes a solution. [0003] In addition, the current electronic braking system has been applied to active safety devices, such as ABS, ESP and so on. Ensuring the reliability of the braking system structurally is an effective way to improve braking performanc...
