  "textContent": "An electric vehicle includes a motor unit (6) to drive a wheel (2). The electric vehicle also includes a control system that controls the motor unit (6). The control system includes an inverter (31). The electric vehicle also includes a temperature sensor (Sma) to sense temperature Tmc of the motor coils (78) of the motor unit (6) or a temperature sensor (Sia) to sense temperature Tic of the inverter (31). The electric vehicle also includes a limiter (95 (102)) to, if the temperature Tmc sensed by the sensor (Sma) exceeds a motor coils temperature threshold, reduce a motor current of the unit (6) until a derivative dTmc/dt of the sensed temperature Tmc with time t drops to zero or below, or to, if the temperature Tic sensed by the sensor (Sia) exceeds an inverter temperature threshold, limit a current command to the inverter (31) until a derivative dTic/dt of the sensed temperature Tic with time t drops to zero or below.",
