  • Electric motor control by torque perturbation
    Patent number: 9764658
    Abstract: A control unit of an electric vehicle receives a signal indicative of an operator desired torque and sends a signal to the traction motor to output a value of torque that is the algebraic sum of the operator desired torque and a torque modification factor calculated by the control unit. The control unit calculates the torque modification factor from an efficiency map of the motor which indicates the efficiency of the motor as a function of its output torque and rotational speed.
