Abstract

The invention relates to a control method of work mode of a hybrid dynamic. A hybrid dynamical entire car control unit HCU comprises a motor administration module, a motor control unit MCU, a module signal of an input pattern administration module having request of quick start-stop, request of auxiliary drive, request of regenerative braking and generating electricity, request of idling and current motor state. When the fault detection module is subjected to fault management, the received signal is request signal of system protection, system fault signal and the current motor state. The output signal mainly comprises request mode, torque and speed. The hybrid dynamical entire car control unit HCU monitors and manages the working mode of the engine and motor, therefore the better energy management than the traditional vehicle is obtained. The most reasonable time and work mode are confirmed and the stable switch of motor work mode is ensured.

Description

technical field [0001] The invention belongs to the field of hybrid electric vehicle control, and realizes the control of the motor working mode by the control unit of the hybrid electric vehicle. Background technique [0002] Energy crisis and environmental degradation are important factors restricting global development. Research on energy-saving and environmentally friendly vehicles is one of the effective means to alleviate energy pressure and reduce environmental pollution. Hybrid electric vehicles take into account the advantages of both internal combustion engine vehicles and pure electric vehicles, and have the advantages of low fuel consumption, low emissions, and long mileage, and are currently a feasible solution. [0003] Since the parallel hybrid has two power sources, the engine and the motor, the hybrid vehicle controller (HCU) needs to determine the working mode according to the current vehicle operating status, and then send power and mode requests to the en...
