The vehicle controller is referred to as VCU (Vehicle Control Unit), which is responsible for the control center of the whole vehicle, and adopts the automotive-grade NXP. The main functions include:
1. Vehicle driving intention judgment;
2. Drive torque distribution and energy consumption management;
3. Logic control of vehicle power on and off;
4. Signal acquisition and vehicle accessory control;
5. Communication transmission and diagnostic monitoring of CAN;
6. Vehicle fault diagnosis management;
7. Vehicle safety management.

製品の利点

  • The program is modularized to differentiate control and strong expandability to meet the needs of different users.
  • The whole vehicle software adopts real-time control with sampling interval time of 1ms, and adopts reasonable underlying driver writing to reduce ineffective sampling and processing, which provides more accurate support for the upper layer application programs such as driver’s intention judgment, strategy analysis, and so on.
  • Active damping control technology, used to eliminate torque pulsations caused by sudden torque changes, the VCU simulates the damping effect by dynamically adjusting the rate of torque rise and fall under the premise of satisfying dynamics and acceleration, thus suppressing vehicle judder.
  • The self-developed control algorithm, with the optimal energy consumption of the motor as the control objective, dynamics and stability as the constraints, obtains the requested torque of the motor, and can independently search for the optimal point of efficiency during the operation of the drive system.
