A controller apparatus for an electric vehicle includes a power supply, a power converting section for converting power supplied from the power supply, a motor which receives an output from the power converting section to drive the electric vehicle; an accelerator opening detector for detecting an accelerator opening; a controller section for controlling said power converting section in response to a detected output from said accelerator opening detector; a current detector for detecting the current supplied to the motor from the power supply; and failure decider for deciding that the controller suffers a failure when the output from the current detector is not smaller than the reference value previously determined in accordance with the accelerator opening, thereby stopping the drive of the motor. In such a structure, the torque not smaller than that required by a driver is produced so that it is possible to prevent the electric vehicle from running away.
