Hybrid power automobile control method based on suspension vibration energy recovery

Abstract

The invention discloses a hybrid power automobile control method based on suspension vibration energy recovery. The control method comprises an energy management control method, a suspension control method and a supervision method for the energy management control method and the suspension control method. According to the energy management control method, an improved minimum equivalent fuel consumption control strategy is adopted, and drive and brake control over a hybrid power automobile is achieved by acquiring the status information of all parts of a power transmission system. The suspension control method is used for acquiring the status information of a suspension system, and determining and outputting ideal control force of all actuators of a suspension. According to the supervision method, real-time adjustment for control parameters in the energy management control process and for control parameters in the suspension control process is achieved through acquired voltage and current signals of all the actuators of the suspension system and the status information including vehicle body vertical accelerations, pitch angle accelerations, bank angle accelerations, vertical accelerations of four wheels and the like; and the vehicle comfort and operating stability are coordinated, and the fuel economy of the hybrid power automobile is effectively improved at the same time.
