Abstract

A vehicle includes at least one sensor generating a signal to control an operation of an internal combustion engine; and a control unit configured to store a control parameter to control an operation of the internal combustion engine, and to correct the control parameter based on an output of the at least one sensor. The control unit stops correcting the control parameter while the vehicle is at a halt, and the power generator is generating electric power by driving of the internal combustion engine.

Claims

1. A control device of a vehicle comprising a power generator and an internal combustion engine, said internal combustion engine used for running said vehicle and for driving said power generator, said control device comprising:

at least one sensor generating a signal to control an operation of said internal combustion engine;

a control unit configured to store a control parameter to control an operation of said internal combustion engine, and to correct said control parameter based on said signal of said at least one sensor, the control unit including;

a parameter updating unit configured to correct said control parameter, and

a prohibition unit instructing said parameter updating unit to prohibit correction of said control parameter when said vehicle is at a halt and said power generator is generating power by driving of said internal combustion engine such that electric power generated from said power generator is output outside of said vehicle by an electric circuit,

said control unit restarting correcting said control parameter when said electric power is no longer output outside of said vehicle.

2. The control device of a vehicle according to claim 1, wherein said control parameter is at least one of an air-fuel ratio, a timing retarding amount of ignition timing, and an air intake amount during an idle operation of said internal combustion engine.

3. A vehicle comprising:

a power generator,

an internal combustion engine used for running said vehicle and for driving said power generator;

at least one sensor generating a signal to control an operation of said internal combustion engine;

a control unit configured to store a control parameter to control an operation of said internal combustion engine, and to correct said control parameter based on said signal of said at least one sensor, the control unit including;

a parameter updating unit configured to correct said control parameter, and

a prohibition unit instructing said parameter updating unit to prohibit correction of said control parameter when said vehicle is at a halt and said power generator is generating power by driving of said internal combustion engine such that electric power generated from said power generator is output outside of said vehicle by an electric circuit,

said control unit restarting correcting said control parameter when said electric power is no longer output outside of said vehicle.

4. A control method of a vehicle comprising a power generator, an internal combustion engine, and an electric circuit configured to allow electric power generated at said power generator to be output outside of said vehicle, said internal combustion engine used for running said vehicle and for driving said power generator, said control method comprising the steps of:

correcting a control parameter to control said internal combustion engine based on an output of at least one sensor generating a signal to control an operation of said internal combustion engine,

correcting said control parameter,

instructing to prohibit correction of said control parameter when said vehicle is at a halt and said power generator is generating power by driving of said internal combustion engine such that electric power generated from said power generator is output outside of said vehicle by an electric circuit,

and

restarting correcting said control parameter when said electric power is no longer output outside of said vehicle.

5. The control method of a vehicle according to claim 4, wherein said control parameter is at least one of an air-fuel ratio, a timing retarding amount of ignition timing, and an air intake amount during an idle operation of said internal combustion engine.
