    摘要: While a voltage value of the battery detected by a battery voltage-detecting part is less than a predetermined threshold voltage value for determining a low voltage state, a rotation sensor malfunction-detecting part stops calculating a vehicle speed and uses the vehicle speed calculated at a time immediately before a time when a voltage value of a battery becomes less than the threshold voltage value for determining the low voltage state, for detecting malfunction in a rotation sensor. Thereby, even if noises due to a voltage fluctuation in the battery mix with the rotation signal from the rotation sensor, since the rotation sensor malfunction-detecting part does not calculate the vehicle speed during a period of time when the voltage value of the battery detected by a battery voltage-detecting part is less than the threshold voltage value for determining the low voltage state, the vehicle speed is not miscalculated based on the rotation signal including noises, and the malfunction in the rotation sensor can be precisely detected.

    摘要: In a vehicular control unit, a main power supply voltage detecting section to detect a voltage value of a main power supply is provided and, an abnormality determining section determines an abnormality occurs in the main power supply voltage detecting section when the main power supply voltage detecting section negatively detects the voltage value of the main power supply and a power supply stop command output section outputs a command to stop the supply of the continuous power supply to the power supply control circuit without an execution of a shut-off process when the abnormality determining section determines that the abnormality occurs in the main power supply voltage detecting section.
