Abstract
A vehicle control apparatus includes an inverter, a torque setting unit that sets a first torque command value of a traveling motor based on an accelerator operation amount, a torque correction unit that corrects the first torque command value to a second torque command value by performing feedback of the result of control of the traveling motor to the first torque command value, an inverter control unit that generates a drive signal of switching elements based on the second torque command value and a carrier signal, and a motor lock determination unit. When the traveling motor is determined to be in the motor lock state by the motor lock determination unit, the torque correction unit sets a feedback gain to be smaller than a threshold gain, and the inverter control unit sets the frequency of the carrier signal to be lower than a threshold frequency.
