Abstract
The engine ECU includes a control CPU and a monitoring CPU. The control CPU has a vehicular engine control function and an electronic throttle control function. The monitoring CPU is connected to the control CPU in an intercommunicative manner. The monitoring CPU communicates with the control CPU to receive data at least on the throttle control from the control CPU. The monitoring CPU determines whether the data from the control CPU is properly received. If the date is not properly received, the monitoring CPU resets the control CPU.
