Most hybrid electric vehicle (HEV) employs both hydraulic braking system and regenerative braking system together, due to the effect of regenerative braking torque; the traditional hydraulic braking control strategy should be adjusted to assure the braking safety.

This paper aims at micro HEV system architecture based on an electric machine and ultracapacitor to analyze the control strategy for the vehicle s regenerative braking,start & stop,launch torque assist system.

It can improve the fuel consumption 、emission and comfort with the help of these advanced functions,such as "start-stop","regenerative braking","torque assistance" and so on.

The energy consumption of a passive suspension via damper and the energy demand for an optimal vehicle active suspension are firstly investigated, showing valuable potential of vibration energy regeneration in an active suspension.
