Abstract

The invention discloses a high-speed vehicle brake test device and a control method thereof, and belongs to the technical field of electro-mechanics. The test device is characterized by mainly comprising a road attachment coefficient simulating device, a mechanical automobile inertia simulating device, a data acquisition and processing part and an experiment device control part. By virtue of the device, the movement inertias of different types of vehicles can be simulated; meanwhile, the brake situations of the vehicles in case of different road attachment coefficients can be simulated, and the brake moment and the slip rate of a vehicle provided with an anti-lock brake system during braking are accurately measured. The performance of the anti-lock brake system of a passenger car can be more accurately evaluated.

Description

technical field [0001] The invention relates to a vehicle high-speed braking test device and a control method thereof, belonging to the field of electromechanical technology, and relates to an indoor braking detection device for high-speed vehicles and a control method thereof. Background technique [0002] Although there are various braking test devices, most of them belong to low-speed braking test devices, which cannot realize the detection of high-speed braking of vehicles, and cannot accurately detect the braking performance of automobile anti-lock braking system. Therefore, the automobile equipped with the brake anti-lock braking system device generally needs to use the method of road detection when detecting the braking performance. The road test needs to build a special runway for the anti-lock brake system, and the construction of a special runway for the anti-lock brake system test requires a lot of funds and takes up a lot of land. The runway needs to be cleaned e...
