ABSTRACT:
A vehicle electronic control system has a control CPU and a monitor CPU. The control CPU performs a fail-safe processing thereby to reduce an engine output torque, when the monitor CPU monitoring the control CPU detects that the control CPU fails to perform throttle control for an engine. When the monitor CPU detects that the control CPU fails to perform the fail-safe processing, it performs a fail-safe processing in place of the control CPU. In this fail-safe processing, the monitor CPU continues to reset the control CPU so that the engine may be forcibly stopped.
