SYSTEM AND METHOD FOR CONTROLLING ENGINE OF HYBRID VEHICLE
First Claim
1. A method for controlling an engine of a hybrid vehicle, the method comprising:
- (a) continuously, by at least one control unit, detecting an output required power with the engine of the vehicle in an Off state, and determining whether the required power exceeds a preset engine delayed ignition power;
(b) determining, by at least one control unit, whether the required power exceeds a preset engine non-delayed ignition power; and
(c) starting, by at least one control unit, the engine when the required power exceeds the engine non-delayed ignition power within a first set time, after the required power exceeds the engine delayed ignition power,wherein the engine non-delayed ignition power is set as a value greater than the engine delayed ignition power.

Abstract
Disclosed is a system and method for controlling an engine of a hybrid vehicle that continuously detects an output required power with the engine of the hybrid vehicle in an Off state, and determines whether the required power exceeds a preset engine delayed ignition power. Then a determination is made as to whether the required power exceeds a preset engine non-delayed ignition power; and when the required power exceeds the engine non-delayed ignition power within a first set time starting the engine, after the required power exceeds the engine delayed ignition power, so that the fuel efficiency and the output efficiency of a hybrid vehicle according to the present invention may be improved.

12. A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:
-
program instructions that continuously determine whether the required power exceeds a preset engine non-delayed ignition power by continuously detecting an output required power with the engine of the vehicle in an Off state, and determining whether the required power exceeds a preset engine delayed ignition power; and program instructions that start the engine when the required power exceeds the engine non-delayed ignition power within a first set time, after the required power exceeds the engine delayed ignition power, wherein the engine non-delayed ignition power is set as a value greater than the engine delayed ignition power. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
