Abstract
A control device comprises: a temperature estimating unit for estimating the temperature of a piston of an internal combustion engine of a vehicle; and a control unit which, if the temperature of the piston estimated by the temperature estimating unit has risen to a first threshold corresponding to a heat resisting temperature of the piston, reduces an upper limit value of a fuel injection timing at which a fuel injector for injecting fuel onto the piston injects the fuel, and which increases the upper limit value of the fuel injection timing at a higher temperature than the first threshold when the rise in temperature of the piston stops.
