Machine.The working condition of electrokinetic cell controller real-time detection electrokinetic cell, the main dump energy (State for obtaining electrokinetic cell
Of Capacity, SOC), provide reference feature for composite braking control strategy.Vehicle control system is by CAN and motor
Controller, electrokinetic cell controller real-time communication, so as to realize that vehicle liquid replies hydraulic brake torque and electricity in conjunction braking procedure by cable
The real-time distribution of mechanism dynamic torque.
Drive control function：Driver performs according to driving intention and drives in operating process, and vehicle control system is according to biography
Sensor measures the signals such as accelerator pedal input, steering wheel angle, speed, longitudinal acceleration, lateral acceleration, and these signals are passed
Vehicle control system is defeated by, comprehensive analysis and judgement are carried out by vehicle control system, calculate the drive of the driver under current state
Dynamic demand, recognize travel condition of vehicle and select configuration (forerunner, rear-guard, 4 wheel driven) and functional mode (dynamic property, economy
Property), the car load torque-demand under sending torque instruction to meet difference in functionality pattern to four electric machine controllers, four motor controls
Device processed sends torque instruction to four wheel hub motors respectively, realizes torque closed loop control.
In the present embodiment, entire car controller, steering mechanism's controller, abs controller, electric machine controller and electrokinetic cell control
Device processed can adopt chip microcontroller.
Compare with traditional combustion engine automobile with centralized driving formula electric automobile, using the electric automobile of In-wheel motor driving,
Each of which wheel can carry out fast driving and braking by wheel hub motor, and using differential steering control steering is substantially increased
Susceptiveness.Due to having deleted the parts such as driveline clutch, differential mechanism, power transmission shaft, chassis structure relative simplicity, car load matter
Amount significantly mitigates, and the lightweight of car load has been reached to the full extent, while being also to realize that chassis system Efficient intelligent is created
Favourable condition.In addition wheel hub motor has that response is rapid, is easy to the advantage that measures, using wheel hub motor and electric machine controller just
The precise control that single or multiple wheels drive and brake can be realized.So as to the straight-line travelling, the turning driving that are just capable of achieving vehicle
And acceleration and deceleration motion.The work(such as the Way of Regenerating Energy Feedback of electric automobile wheel are easily realized using the electric automobile of In-wheel motor driving
Energy.
