Active motor damping to mitigate electric vehicle driveline oscillations

摘要: A system and method for actively damping driveline oscillations in a motor vehicle having traction to drive vehicle's wheels an antilock brake (ABS). controller controls torque output signal of the effectively dampen during ABS operation. proportional, proportional derivative, or derivative may be used generate based on at least one speed, average wheel speeds, difference two angular acceleration, accelerations. Motor speed signals filtered eliminate high frequency components each signal. Additionally, amplitude limited within positive upper negative lower active limit.
