Electric Vehicle Torque Control for Wheel Slip Suppression

The patent achieves slip prevention through a multi-functional control strategy that serves multiple purposes simultaneously. The torque differentiation mechanism not only prevents simultaneous slip but also optimizes traction utilization, improves vehicle stability, and enhances starting performance on slopes. By consolidating these functions into a single control framework, the patent minimizes additional complexity while maximizing benefits.

The patent employs feedback control by continuously monitoring wheel speed and detecting slip conditions, then using this information to dynamically adjust torque commands to front and rear motors. The feedback loop compares actual wheel speed with expected speed and modifies torque distribution accordingly. This closed-loop control approach automates the slip prevention process, reducing the perceived complexity for the driver while maintaining reliable simultaneous slip suppression.
