Abstract: An integrated electro-hydraulic brake system was proposed, and the coordinated control strategy of regenerative braking force and hydraulic braking force was studied under non-emergency/emergency braking conditions. The principle of the electric-hydraulic brake system with an integrated master cylinder was analyzed, and the basic control strategy for the two braking conditions was proposed. Brake force distribution strategy between regenerative braking force and hydraulic braking force under non-emergency condition was investigated. Two cases triggering the anti-lock braking system were presented. Cooperative control between electric-hydraulic brake and anti-lock brake using hydraulic braking force was studied with simplified control logic. Hardware-in-the-loop test bench was built using xPC target, and non-emergency/emergency braking tests were carried out. Test results show that the proposed integrated electro-hydraulic brake system and braking force cooperative control strategy can meet the braking energy recovery and coordination with the anti-lock brake control needs.

Key words: automotive engineering, electro-hydraulic brake system, regenerative brake, anti-lock braking system, cooperative control
