Strong extensibility

The program is modularized to differentiate control and strong expandability to meet the needs of different users.
Efficient control

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.
Stability control

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.
Technical Advantages

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.
