Hybrid Control Unit

Hybrid Control Unit is the core control component of hybrid vehicle (HEV/PHEV).

 

      Hybrid vehicles are one of the technical means to reduce environmental pollution and reduce energy consumption in the automobile industry. Hybrid control unit is one of the key components in hybrid cars, hybrid electric vehicle is the key to a hybrid system, it is directly related to the performance of hybrid vehicle performance, the hybrid powertrain by power transmission line, can be divided into series, parallel and mixed type 3 kinds.

       Hybrid control unit main function is to control the vehicle power and working mode of switching control, the vehicle energy control system as a hybrid car of the brain, each subsystem coordination command, in order to achieve efficiency, emission and power performance of the best match, at the same time balancing the ride comfort of vehicle. According to the driver's operation, such as the accelerator pedal, brake pedal, the operation of the shift lever, etc., determine the driver's intention, on the premise of meet the demand of the pilot, allocation, engine parts, batteries, and the power of the motor power output, the realization of the optimal management of energy utilization, make limited fuel for the maximum effect. Energy control also needs to consider the energy consumption of other vehicle-mounted electrical accessories and mechanical accessories, such as air conditioning, power steering and braking power consumption, to comprehensively consider the energy use of the vehicle.
