Abstract
An engine ECU executes a program including the steps of: if it is necessary to take an anti catalytic odor approach and the engine should be warmed up, resetting an engine warm up request flag to cut fuel for the approach; cutting the fuel and determining whether the approach has completed; and if so, setting the flag.
Claims32
A vehicular control device for a vehicle having mounted therein an internal combustion engine with an exhaust manifold provided with a catalytic device cleaning emissions, comprising:
- a fuel supplier supplying said internal combustion engine with fuel;
- a detector detecting that said catalytic device generates catalytic odor and/or a prediction that said catalytic device generates said catalytic odor;
- an interrupter temporarily interrupting said fuel supplied from said fuel supplier;
- and
- a controller controlling said vehicle, as based on whether said interrupter's temporal interruption of said fuel is attributed to said catalytic odor.
A vehicular control device controlling a vehicle having mounted therein an internal combustion engine with an exhaust manifold provided with a catalytic device cleaning emissions and a dynamo-electric machine connected to said internal combustion engine to generate a torque stopping said internal combustion engine from rotating, comprising:
- a detector detecting that said catalytic device generates catalytic odor and/or a prediction that said catalytic device generates said catalytic odor;
- and
- a controller operative in response to said catalytic odor to control said vehicle to rotate said internal combustion engine by said dynamo-electric machine after said engine halts.
A vehicular control device for a vehicle having mounted therein an internal combustion engine with an exhaust manifold provided with a catalytic device cleaning emissions, comprising:
- fuel supply means for supplying said internal combustion engine with fuel;
- detection means for detecting that said catalytic device generates catalytic odor and/or a prediction that said catalytic device generates said catalytic odor;
- interruption means for temporarily interrupting said fuel supplied from said fuel supply means;
- and
- control means for controlling said vehicle, as based on whether said interruption means's temporal interruption of said fuel is attributed to said catalytic odor.
A vehicular control device controlling a vehicle having mounted therein an internal combustion engine with an exhaust manifold provided with a catalytic device cleaning emissions and a dynamo-electric machine connected to said internal combustion engine to generate a torque stopping said internal combustion engine from rotating, comprising:
- detection means for detecting that said catalytic device generates catalytic odor and/or a prediction that said catalytic device generates said catalytic odor;
- and
- control means operative in response to said catalytic odor for controlling said vehicle to rotate said internal combustion engine by said dynamo-electric machine after said engine halts.
