vehicle control unit/hybrid control unit for new energy vehicles
overview
new energy vehicles can be classified into electric vehicles (ev) and hybrid electrical vehicles/ plug-in hybrid electric vehicles (hev\phev) according to their power sources. the vehicle control unit is the core control component of the new energy vehicle. the main function is to analyze the driver's demand, monitor the driving state of the car, and coordinate the control unit such as bms, mcu, ems, tcu, etc. to realize the power-on/off, drive control, energy recovery, accessory control and fault diagnosis of the vehicle.
