The generation mechanism of regenerative braking torque based on a novel voltage variable charging control method will be analyzed and the corresponding rule base will be designed. The mathematical description method of the dynamic evolution process during the switching process between the regenerative braking mode and hydraulic braking mode will be studied; meanwhile, the discriminate method and criterion of mode switching stability will be established. The coordinated control strategy of composite braking system for double rotor hub motor driven electric vehicle will be researched under both non-emergency and emergency braking situations. The coupling mechanism of composite ABS control based on the regenerative-hydraulic braking system under the emergency braking situation will be ascertained; and the composite ABS control strategy for regenerative-hydraulic braking system, considering both braking safety and energy recovery efficiency, will be proposed. This research will provide significant academic significance and engineering application value to improve both braking performances and energy utilization efficiency for electric vehicle, as well as to promote the industrialization process of electric vehicle.
