Embodiment Construction

[0021] The invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] like figure 1 As shown, the present invention includes an oil storage cup 1, a brake master cylinder 2, and a brake pedal 4 with a pedal stroke sensor 5. A simulator valve block 22 is connected between the first chamber and the second chamber of the brake master cylinder 2 and the ABS valve block 20 .

[0023] The simulator valve block 22 includes four solenoid valves 12, 13, 14, 15, a pressure sensor 8, and a simulator cylinder block 19; the hydraulic oil in the first chamber of the brake master cylinder 2 is connected to the simulator valve block The pressure sensor 8 of 22 is divided into two paths, one path is connected in series with the third solenoid valve 14 and connected with the ABS valve block 20, and the other path is connected in series with the fourth solenoid valve 15 and connected with the cavity without simulator spring 17 of the simula...

Abstract

The invention discloses a simulator for feeling an automobile brake pedal, comprising an oil storage cup, a brake master cylinder and a brake pedal which is provided with a pedal stroke sensor; a simulator valve block is connected between the first chamber and second chamber of the brake master cylinder and an ABS valve block; the hydraulic oil in the first chamber of the brake master cylinder is accessed into the simulator valve block and then is divided into two paths after passing a pressure sensor; one path of the hydraulic oil in series connection with a third electromagnetic valve is connected with the ABS valve block, the other path in series connection with a fourth electromagnetic valve is connected with stimulator-free spring chamber of a stimulator cylinder body; the hydraulic oil in the second chamber of the brake master cylinder is accessed into the simulator valve block and then is divided into two paths; one path of the hydraulic oil in series connection with a second electromagnetic valve is connected with the ABS valve block, the other path in series connection with a first electromagnetic valve is connected with the oil storage cup; and the stimulator spring chamber of the stimulator cylinder body is connected with the oil storage cup. The simulator has simple structure, is convenient for being installed in an automobile, can accurately obtain the brake intention of a driver and truly feed back the feeling of the driver stamping the pedal, and can realize emergent brake function of an electronic control braking system; and the property of the pedal is stable.

Description

technical field [0001] The invention relates to an automobile electric control braking system device, in particular to an automobile brake pedal feeling simulator. 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 braking system has many advantages such as simple structure, fast braking response, high control precision, flexible layout, and consistent pedal characteristics; The demand for regenerative braking systems of automobiles and hybrid electric vehicles has a good development prospect. However, the electronic control braking system cancels the direct connection between the brake pedal and the brake wheel cylinder, and a specific device must be used to simulate the feedback force of the brake pedal to ensure that the driver obtains brake feedback information. Therefore, a pedal feel simulator that can accurately and reliably re...
