Provided are a control device for an electric vehicle, an electric vehicle, and a recording medium on which a computer program is recorded, with which it is possible to determine an abnormality in a control parameter of a drive motor. A control device for an electric vehicle acquires a detection value of an output current of a battery detected by a first sensor and a detection value of a drive torque transmitted to a wheel detected by a second sensor, and calculates an actual torque-current characteristic indicating a relationship between a supply current to an inverter circuit and the drive torque transmitted to the wheel. The deviation between the calculated actual torque-current characteristic and a reference torque-current characteristic in which the relationship between the torque instruction value of the drive motor and the target supply current to the drive motor is set in advance is determined.
提供一种能够判定驱动用马达的控制参数的异常的电动车辆的控制装置、电动车辆以及记录有计算机程序的记录介质。电动车辆的控制装置获取由第一传感器检测出的电池的输出电流的检测值和由第二传感器检测出的传递至车轮的驱动扭矩的检测值,计算表示向逆变器电路的供给电流与传递至车轮的驱动扭矩之间的关系的实际扭矩‑电流特性,并判定预先设定了驱动用马达的扭矩指示值与向驱动用马达的目标供给电流之间的关系的基准扭矩‑电流特性与计算出的实际扭矩‑电流特性之间的偏差。
