Obtain, but directly use under same environment, so main control chip adopts BGA package, meet substantial amounts of fan-in fanout.
This not only avoids when VCU and TCU is individually controlled to the repeated sampling of many signals, double counting, the worry for repeating diagnosis, keep away
Exempt from the trouble that CAN communication speed and capacity limit bring, and these aggregation of variable get up and can be to the running status of vehicle
Have and more fully understand, the self study and diagnosis to some variables provides more fully information, therefore more accurate, completeer
It is whole, more reliable.
Electrical vehicular power assembly master controller can also be effectively assessed the required moment of torsion of driver, in battery electricity
The multifactor condition such as amount, road conditions, vehicle condition is made decision the optimal output torque of motor.Conventional engine machine controller is only according to driver
Demand determine engine output torque, the demand of driver is determined by the depth of stepping on accelerator pedal, and electrical vehicular power
The advantage that assembly master controller can simultaneously be controlled by motor and variator, by judging current gear and whether preparing
Switching gear etc. determining the optimal output torque of motor, the working condition of the gear switch of variator also dependent on electromotor
To determine in real time；In gear shift, the output torque of motor is not equal to the moment of torsion of driver's needs, and to meet the spy of variator
It is different to need to increase the driver comfort of driver；On different road surfaces, the output torque of motor can also be carried out effectively
Optimization.
In braking, how to reclaim the energy is how to distribute friction to consume and generate electricity recovery vehicle energy most possibly
Ratio, be it is very important, due to generate electricity it is more, friction consume it is less, rub consume speed brake quickly, that is, away from
From very short, friction is consumed and generated electricity and reclaims kinetic energy and can more shorten braking distance to improve safety, so response time is especially weighed
Will.Such as entire car controller is received tells GCU, GCU to receive after signal just to take action by CAN again after brake signal,
Just once time delay, if TCU notifies that VCU, VCU are received after signal again by CAN notices among gear shift by CAN
GCU, GCU received and taken action again after signal, just there is secondary delay, and in the case where there is emergency, time delay also brings along wind
Danger, and the just no any time delay of electrical vehicular power assembly master controller, so as to ensure that the rapidity and reliability of system.
