Vehicle Torque Control During Regenerative Braking Near Zero Load

The control apparatus applies preliminary anti-action by detecting when the motor torque is near zero during regenerative braking and proactively suppressing torque correction in this critical region. This prevents the gear contact surface changes that cause kickback and abnormal noise before they occur, while still maintaining overall vehicle behavior stability through controlled torque adjustment.

The patent implements parameter changes by dynamically adjusting the torque correction amount based on the motor's operating state. When the motor torque approaches zero during regenerative braking, the control apparatus reduces or suspends torque correction, thereby changing the control parameter to avoid kickback while maintaining vehicle stability control in other operating regions.

The control apparatus uses feedback by continuously monitoring the motor's torque output and regenerative braking state. When feedback indicates that torque is near zero during regenerative braking, the system automatically suppresses torque correction to prevent impact and noise, while maintaining driving stability through regulated torque adjustment based on real-time operating conditions.

The patent applies dynamics by making the torque correction control adaptive rather than fixed. The control apparatus dynamically adjusts whether torque correction is applied based on the current operating state - suppressing correction when motor torque is near zero during regenerative braking to prevent noise, while allowing correction in other states to maintain driving stability.
