Title
(EN) Error determination device and error determination method of control system
Abstract
(EN)

When a determination is made that a signal transmitted by a voltage sensor, a second voltage sensor, a current sensor, a temperature sensor, a second temperature sensor, a first CPU, a second CPU and a communication circuit is in error, a third CPU of a motor generator ECU determines that the control system is in error. When a determination is made that the control system is in error, the third CPU determines whether each of the voltage sensors, the current sensor, the temperature sensors, the first CPU, the second CPU and the communication circuit is in error or not.
