能制限手段とを備えた内燃エンジンの制御装置。 The operation of the internal combustion engine is controlled by a plurality of sensors attached to the engine, and if a failure occurs in some of the sensors, backup can be performed using only the other sensors. In a control device that switches control, a determining means for determining whether the failure is severe or minor, and a functional restriction that partially reduces driving functions so that the driver can intuitively recognize when the determining means determines that the failure is severe. A control device for an internal combustion engine comprising means.
