INJECTOR-CORRECTING APPARATUS OF A HYBRID ELECTRIC VEHICLE AND A METHOD THEREOF
First Claim
1. An injector correcting apparatus of a hybrid electric vehicle, comprising:
- an engine generating power by combustion of a fuel;
a motor supporting power of the engine and selectively operating as a generator;
a clutch provided between the engine and the motor;
an injector injecting the fuel to a combustion chamber of the engine;
a driving information detector detecting driving information of the vehicle including driving distance of the vehicle, vehicle speed, coolant temperature, fuel temperature, and state of charge (SOC) of a battery; and
a controller correcting the fuel injection by increasing a fuel amount supplied to the combustion chamber step-by-step when a correcting condition of the injector derived from the driving information detected by the driving information detector is satisfied, while the vehicle is coasting.

Abstract
An injector correcting apparatus of a hybrid electric vehicle may include an engine generating power by combustion of a fuel, a motor supporting power of the engine and selectively operating as a generator, a clutch provided between the engine and the motor, an injector injecting the fuel to a combustion chamber of the engine, a driving information detector detecting driving information of a vehicle including driving distance of the vehicle, vehicle speed, coolant temperature, fuel temperature, and state of charge (SOC) of a battery, and a controller correcting fuel injection by increasing a fuel amount supplied to the combustion chamber step-by-step when a correcting condition of the injector derived from the driving information detected by the driving information detector is satisfied, while the vehicle is coasting.

5. An injector correcting apparatus of a hybrid electric vehicle comprising:
-
an engine generating power by combustion of a fuel; an HSG starting the engine and selectively operating as a generator; a motor supporting power of the engine and selectively operating as another generator; a clutch provided between the engine and the motor; an injector injecting the fuel to a combustion chamber of the engine; a driving information detector detecting driving information of the vehicle including driving distance of the vehicle, vehicle speed, coolant temperature, fuel temperature, and SOC of a battery; and a controller correcting the fuel injection by increasing a fuel amount supplied to the combustion chamber step-by-step when a forcible correcting condition of the injector is satisfied and a correcting condition of the injector derived from the driving information detected by the driving information detector is satisfied. - View Dependent Claims (6, 7, 8)

9. An injector correcting method of a hybrid electric vehicle having an engine generating power by combustion of a fuel, a motor supporting power of the engine and selectively operating as a generator, a clutch provided between the engine and the motor, an injector injecting the fuel to a combustion chamber of the engine, a driving information detector detecting driving information of the vehicle, and a controller correcting the injector according to a driving condition of the vehicle, including the controller executing a set of instructions for:
-
receiving driving information of the vehicle including driving distance of the vehicle, vehicle speed, coolant temperature, fuel temperature, and SOC of a battery; determining whether a forcible correcting condition of the injector is satisfied; determining whether the driving distance of the vehicle is higher than a correcting driving distance for correcting the injector when the forcible correcting condition of the injector is not satisfied; determining whether the vehicle is coasting and the injector correcting condition is satisfied when the driving distance of the vehicle is higher than a correcting driving distance; and correcting the fuel injection of the injector by using a time of explosion of the fuel in the combustion chamber while increasing a fuel amount injected to the combustion chamber of the engine step-by-step when the injector correcting condition is satisfied. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
