Abstract
A vehicle controller which can realize a reduced cost and high reliability at the same time. A control target status signal outputted from a control target is inputted to a monitoring unit. The monitoring unit compares a control command value with the control target status signal to determine whether the control target operates normally as per the control command value. When the monitoring unit determines that the control target does not operate normally, it outputs a failure detected signal to an actuator driving unit.
