Claim:
1. A control apparatus of an electrically-driven vehicle controlling an electrically-driven vehicle that includes a motor transmitting a drive force to wheels, an inverter driving the motor, and a battery supplying power to the inverter, the control apparatus comprising: a battery storage amount estimator to estimate a storage amount of the battery; a motor rotation speed detector to detect a rotation speed of the motor; a micro-computer to compare the detected rotation speed with a first predetermined rotation speed in response to the micro-computer determining that the inverter is under a normal operation without being short-circuited, and compare the detected rotation speed with a second predetermined rotation speed, which is lower than the first predetermined rotation speed, in response to the micro-computer determining that the output terminals of the inverter are short-circuited; and an inverter controller to short-circuit output terminals of the inverter in response to the rotation speed of the motor reaching or exceeding the first predetermined rotation speed while the estimated storage amount of the battery is equal to or greater than a predetermined amount, and wherein the micro-computer stops applying a short-circuit to the output terminals of the inverter in response to the rotation speed of the motor being lower than the second predetermined rotation speed.
