Range extending type whole electric automobile control system and method

Abstract

The invention discloses a range extending type whole electric automobile control system and method. The control system comprises a low-pressure automobile body CAN control system, a whole automobile controller, a motor controller, a generator controller, a battery management system and an insulating detecting unit. According to the control method, when the energy of an automobile power battery is stored sufficiently, a pure electric work mode can be achieved, energy is saved, and environmental friendliness is achieved; when the energy storage consumption of the power battery reaches to a certain degree, the mode of an automobile is switched into a range extending mode, a generator is driven to work to generate electricity to compensate for certain energy, and therefore the driving range of the automobile can be increased. According to the control system and method, the automobile can work in a pure electric mode so that emission can be reduced, the automobile can work in the range extending mode so that the driving range can be increased, the whole automobile control and the energy distribution management of the range extending type electric automobile are achieved, low emission can be achieved, and the driving range can be increased.

Description

technical field [0001] The invention relates to new energy vehicle control technology, in particular to a vehicle control system and control method for an extended-range electric vehicle. Background technique [0002] With the strengthening of the protection and conservation awareness of non-renewable energy around the world, countries have successively carried out the research and development of new energy vehicles. The mainstream of the developed models are pure electric and hybrid vehicles. Pure electric vehicles have zero emissions and are the first choice for energy saving. However, due to the constraints of the key technology of the battery, the mileage of the vehicle is very limited. Although the mileage of the hybrid vehicle is guaranteed, the effect in terms of energy saving and emission reduction is not obvious. Contents of the invention [0003] In view of this, the object of the present invention is to propose a vehicle control system and control method for an ...
