Abstract
The invention relates to a pneumoelectric hybrid power passenger vehicle control system and a control method of the pneumoelectric hybrid power passenger vehicle control system. The vehicle control system comprises a vehicle controller, a battery mechanism, a high-voltage power distribution box, a motor controller, a driving motor, an engine, a BSG motor or ISG motor, a speed reducer, an instrument mechanism, a gear mechanism, a braking mechanism, an accelerator mechanism, a power generator and a super capacitor, wherein the engine is in hybrid linkage with the driving motor, and the engine is driven and started by the BSG motor; the power generator is assembled at the power output end of the driving motor; the super capacitor is connected with the vehicle controller through a CAN bus. According to the vehicle control system, the high-speed-CAN-bus-based distributed power system control network with the vehicle controller as a main node is used, distribution of power of the motor is calculated through comprehensive vehicle information, the SOC, the temperature, the voltage and the current of a battery, the temperature information of the motor, and other information, and therefore the vehicle can be driven, braking energy feedback of the vehicle can be achieved, and the best driving performance can be acquired under allowance of the system.
Description
technical field [0001] The invention relates to a vehicle control system and a control method thereof, in particular to a gas-electric hybrid bus vehicle control system and a control method thereof. Background technique [0002] A plug-in hybrid electric bus is a complex system composed of multiple subsystems, mainly including power batteries, super capacitors, drive motors, engines, BSG starters (or ISG motors), gearboxes, brakes and other power systems, and other Accessories such as air conditioning, power steering, etc. Each subsystem almost completes its own functions and goals through its own control unit (ECU). In order to meet the goals of vehicle power, economy, safety and comfort, on the one hand, it must have an intelligent human-vehicle interaction interface; on the other hand, each system must cooperate with each other to optimize matching. Therefore, electric vehicles must require a vehicle controller to manage the various components in the electric vehicle. ...
