Driving cycle is controlled with vehicle accessory, carries out that intelligence is known to distribute, and front and rear mode of operation can intelligently switch, can independently drive,
To the acceleration of vehicle, fuel economy, charcoal the Emission Optimization, riding stability etc. is significantly improved.
Hybrid power full-vehicle control unit dominates the moment of torsion under the switching of various patterns, and various types of vehicles driving cycle
Distribution.
According to dynamic structure, 4 kinds of dynamic modes, respectively electric-only mode, series model (SHEV) and gang mould can be divided
Formula (PHEV), engine mode；
According to driving cycle, braking energy under point 15 kinds of patterns, respectively pure electric Drive Mode, electric-only mode can be changed
Slided under recovery, electric-only mode under energy regenerating, series drive mode, series model under Brake energy recovery, series model
Slide and slide energy regenerating, pure electricity under energy regenerating, parallel drive pattern, paralleling model under Brake energy recovery, paralleling model
Dynamic crawling drive pattern, series connection crawling drive pattern, crawling drive pattern in parallel, engine mode；
Shown according to instrument, 4 kinds of patterns, respectively EV+ECO patterns, HEV+ECO patterns, EV+Sport moulds can be divided into
Formula and HEV+Sport patterns.
EV+ECO patterns:Only include pure power mode.EV+SPORT patterns：Only include pure power mode.Electric-only mode, rear-guard
Motor output positive-torque driving vehicle operation.
Brake energy recovery under electric-only mode：Under certain vehicle speed condition, driver touches on the brake pedal, HCU (hybrid powers
Full-vehicle control unit) negative torque is sent to electric machine controller, rear-guard motor output negative torque carries out energy regenerating.
Energy regenerating is slided under electric-only mode：Under certain vehicle speed condition, driver's accelerator releasing, HCU sends negative torque electricity
Machine controller, rear-guard motor output negative torque carries out energy regenerating.
