Abstract

The invention discloses a hardware-in-loop test bed of a hybrid car brake coordination control system, which comprises a driver operation test system (1), a hydraulic brake test system (48), a data processing module (46) a model simulation test system and a motor brake test system (19), wherein, a hydraulic control valve (58) in the hydraulic brake test system (48) is a test object and can be replaced by other hydraulic valves to be tested for testing hydraulic work characteristic. A permanent magnet synchronous motor (34) in the motor brake test system (19) is the test object and can be replaced by other motors to be tested for testing energy recycling characteristic. A brake operation mechanism in the driver operation test system (1) is the test object and can be replaced by other operation mechanisms to be tested for testing the relation of master cylinder pressure, footplate stroke and footplate force. The hardware-in-loop test bed of the hybrid car brake coordination control system can carry out the integral performance test of the hybrid car brake control system which comprises hardware and control strategy.

Description

technical field [0001] The invention relates to a test device for a brake control system of a hybrid electric car, more precisely, it relates to a hardware-in-loop test bench for a brake coordination control system of a hybrid electric car. Background technique [0002] With the global energy crisis and environmental pollution, the energy-saving effect of hybrid electric cars is becoming more and more prominent. Among the various energy-saving technologies of hybrid electric cars, regenerative braking energy recovery technology is one of the key technologies of hybrid electric cars. A coordinated control system of regenerative braking and hydraulic braking of a hybrid car should ensure significant energy recovery, stable braking performance, comfortable braking feeling and excellent safety performance, so that in its research and development process Therefore, an effective test device is needed to conduct strict tests and experiments on the coordination control system from h...
