Description
Summary:The control strategy of the EHB (electronic hydraulic braking) system on hardware-in-loop simulation test-platform is presented based on driver's command via brake pedal sensor. Firstly, a fuzzy logic control method is used to identify the drivers' breaking intention. Then, PID control methods are used to control the switching of the solenoid valve to regulate the wheel brake cylinder pressure. After that, emergency braking procedure simulation is made to test the effectiveness of this control strategy. The proposed control strategy shows very good performance in an emergency braking event which can shorten the response time to improve driving safety.
