State, vehicle system and power consumption is set to be in optimum state.
Pure motor driving pattern：Work as motor status, battery electric quantity, vehicle atmospheric pressure value, 24V magnitudes of voltage, pure power drive system
State meets during condition that driver steps on the throttle after pedal, and dynamical system can combine the information such as itself SOC situation and accelerator open degree, meter
The electricity needed for driving vehicle is calculated, is individually driven by battery/motor and is shifted gears automatically.Thus driven using motor
Motor-car, into pure electric drive mode.
Energy recuperation mode：When the vehicle is decelerating, in the case where unclamping throttle or touching on the brake, system will enter energy
The braking energy of vehicle in the generator mode, is converted into power storage in the battery by recovery state, now motor work
For future use.When wherein braking, dynamical system braking moment, lifting motor charging effect is substantially improved in gearbox speed-regulating function
Rate.
The program provides the solution of pure power drive system for heavy-duty commercial vehicle, there is provided motor adds the machine of gearbox
The automatic assembly of tool and drive control strategy.Being coordinated by motor, major-minor case order it is synchronous by way of complete multi-gear transmission
The pure motorized motions mode of case commercial car power assembly.Compared with electric-machine directly-driven scheme, the heavy truck drive assembly with gearbox
The benefit brought has：Reduce power of motor, reduce lower to motor demand, electric system cost；Reduce motor, battery work electricity
Stream, greatly improves security；Dynamic property improves, and climbable gradient is substantially improved, and grade climbing performance is light>20%；Motor continuous firing is in height
Area is imitated, it is more stable, it is more reliable；Dynamical system power consumption is greatly reduced（Reduction by 10 ~ 15% is compared with straight drive)；Lift max. speed,
And stabilizing speed section is higher, scope is wider；Motor rotating speed, lifting motor braking are lifted by gearbox during braking
Energy.
