Abstract

The invention belongs to a brake hydraulic pipeline exhausting method and particularly relates to a hydraulic system automatic exhausting device and method for an electro-hydraulic brake test bed. Thedevice comprises a front brake wheel cylinder, a test bed body, a transparent hose, a rear brake wheel cylinder, a vehicle electronic stabilization system, a brake master cylinder, a liquid storage pot, an electronic mechanical brake booster, a support, a brake pedal, an adjustable seat, a signal acquisition and transmission platform, a PC, brake master cylinder hydraulic pipelines, two-positiontwo-way solenoid valves, caliper disk brakes and brake wheel cylinder hydraulic pipelines. The device automatically judges the exhausting completion moment through recognition processing according tothe state, acquired by cameras, of brake fluid discharged from the transparent hose, controls rotation of a motor through an ECU of the mechanical brake booster to achieve operations of treadling a pedal and loosening the pedal by simulating a person. The device can be more accurate, efficient, convenient and thorough in automatic exhausting control. The problems that time and labor are wasted, exhausting is incomplete and brake fluid corrodes operators can be solved.

Description

technical field [0001] The invention belongs to a brake hydraulic pipeline exhaust method, in particular to an automatic exhaust device and method for a hydraulic system of an electro-hydraulic brake test bench. Background technique [0002] With the development of the times and the advancement of technology, the automobile braking system has developed from the initial human braking and hydraulic braking to the integrated electro-hydraulic braking system, which not only reduces the driver's operating burden and improves the driving safety of the car and it is easy to realize the integration and intelligence of the car. However, once air appears in the hydraulic brake pipeline, it will cause the brake pressure to drop or even cause the brake to fail, posing a huge safety hazard. For automobile OEMs, they usually evacuate the brake hydraulic pipeline, and then fill the brake fluid into the pipeline with high pressure to exhaust all the air. However, in the actual use of the c...
