Abstract

The invention discloses a sensation simulator of an automobile brake pedal. The rod-free cavity of a main braking cylinder is provided with a piston return spring and is respectively communicated with an oil storage cup and the input end of a two-position three-way solenoid valve; the brake pedal is respectively connected with the push rod of the main cylinder braking piston and a pedal travel sensor; and two output ends of the two-position three-way solenoid valve are respectively connected with a hydraulic control unit (HCU) and a simulator valve block. According to the sensation simulator,the braking sensation of a driver can be accurately obtained, and the pedal feeling of the driver can be fed back. The traditional hydraulic braking system is improved slightly, and the sensation simulator is installed on the main braking cylinder or is integrated with the HCU. The sensation simulator has the advantages of small volume, low cost and small difficulty. Under the condition that a motor-driven hydraulic braking system fails, the traditional hydraulic braking system can be subjected to emergent braking. The sensation simulator of an automobile brake pedal and the HCU guarantee good braking feeling under the coordination control of an electronic control unit (ECU).

Description

technical field [0001] The invention relates to an automobile brake pedal feeling simulator, in particular to an automobile brake pedal feeling simulator capable of feedbacking the pedal feeling. Background technique [0002] The braking system is an important guarantee for the safe driving of a car. Compared with the traditional hydraulic braking system, the electronically controlled hydraulic braking system has many advantages such as simple structure, fast braking response, high control precision, flexible layout, and consistent pedal characteristics; and it is easy to integrate with the automobile braking control system, which can It meets the needs of regenerative braking systems of electric vehicles and hybrid vehicles, and has a good development prospect. [0003] According to relevant patent documents, the patents on brake pedal feeling simulator include pedal simulator integrating force sensor and stroke sensor (US6464306B2), braking force generating device of hydr...
