A vehicle control apparatus can continue a control function against abnormality in operation of an arithmetic processor and in the power supply voltage, and capable of improving reliability. Where there is no abnormality, the autonomous travel control unit and an auxiliary control unit calculate control instruction values for automatic driving control, and validate a CAN communication circuit of autonomous travel control units while invalidating a CAN communication circuit of the auxiliary control unit. Where an abnormality occurs in the autonomous travel control unit and not the auxiliary control unit, the CAN communication circuit of the autonomous travel control unit is invalidated and the CAN communication circuit of the auxiliary control unit is validated. Where the auxiliary control unit has no abnormality when the autonomous travel control unit has an abnormality during automatic driving control thereof, seamless automatic driving control with substantially no time lag continues.

Vehicle control apparatus

The electronic control unit ECU includes: a basethat has a bottom surface portionon which a printed circuit boardis mounted and an opening opposed to the bottom surface portion; and a coverthat covers at least a part of the bottom surface portionand is engaged with the base. Here, the coverincludes an overlap portionthat is spaced apart from and opposed to a side surfaceof the base, and the overlap portionincludes a slit
