Abstract

The invention relates to a vehicle and a control power system thereof. The control power system comprises a whole vehicle control motor used for driving a whole vehicle to operate, an accessory driving motor, electric accessories, and an accessory driving motor controller that is connected with a whole vehicle controller and in control connection with the accessory driving motor; the accessory driving motor is in transmission connection with the electric accessories, and the electric accessory comprises at least two of a low-voltage generator, an air compressor, an air conditioner compressor and a cooling water pump. According to the system, one accessory driving motor and the corresponding accessory motor controller are independently adopted to drive a plurality of vehicle electric accessories, i.e., the plurality of electric accessories share one accessory driving motor and one controller, which is beneficial to the integrated arrangement of the whole vehicle, the cost reduction andthe high-efficiency utilization of energy.

Description

technical field [0001] The invention relates to a vehicle and its control power system, belonging to the technical field of vehicle power systems. Background technique [0002] At present, the main electric commercial vehicles, taking the electric bus as an example, the independent accessory assembly and control system used by most electric buses, the structure diagram is as follows figure 1 shown. Adopt independent electric steering oil pump, electric air compressor, electric air-conditioning compressor, electric cooling water pump and four electric accessories and corresponding controllers, as well as DC-DC converters (or choose low-voltage generators instead of DC-DC converters) . In this way, there are a large number of electric accessory assemblies for the whole vehicle, which increases the difficulty of the layout of the whole vehicle, and the corresponding power distribution and wiring harness layout are particularly cumbersome; secondly, multiple motors and corresp...
