HYBRID ELECTRONIC VEHICLE AND CONTROLLING METHOD THEREOF
First Claim
1. A hybrid vehicle, comprising:
- a battery;
a motor configured to generate a driving torque by using the battery;
an engine configured to charge the battery or generate a driving torque together with the motor;
a driving controller configured to operate the motor and the engine; and
an air conditioning controller configured to execute a heat function by a heat of an engine coolant and transmit an engine-drive-requiring signal to the driving controller to heat the engine coolant,wherein, when a first condition in which a temperature of the engine coolant is equal to or greater than a first temperature and a second condition in which a driving torque generated by the motor is sufficient to move the hybrid vehicle are satisfied, the driving controller is configured to stop operating the engine by a time that a driving torque generated by the engine is required to move the hybrid vehicle regardless of receiving the engine-drive-requiring signal.

Abstract
A hybrid vehicle is provided that includes a battery, a motor that is configured to generate a driving torque using the battery, and an engine that is configured to charge the battery or generate a driving torque together with the motor. A driving controller operates the motor and the engine and an air conditioning controller executes a heat function by a heat of an engine coolant and transmits an engine-drive-requiring signal to the driving controller to heat the engine coolant. When a first condition that a temperature of the engine coolant is greater than a first temperature and a second condition that a driving torque generated by the motor is sufficient to move the hybrid vehicle are satisfied, the engine operation is stopped by a time that a driving torque generated by the engine is required to move the hybrid vehicle regardless of receiving the engine-drive-requiring signal.

8. A controlling method of a hybrid vehicle, comprising:
-
receiving, by a controller, an engine-drive-requiring signal from an air-conditioning controller for heating an engine coolant; determining, by the controller, whether a first condition in which a temperature of the engine coolant is equal or to greater than a first temperature and a second condition in which a driving torque generated by a motor is sufficient to move the hybrid vehicle are satisfied; and stopping, by the controller, operation of an engine when the first and second conditions are satisfied, by a time that a driving torque generated by the engine is required to move the hybrid vehicle regardless of receiving the engine-drive-requiring signal. - View Dependent Claims (9, 10, 11, 12)

13. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:
-
program instructions that receive an engine-drive-requiring signal from an air-conditioning controller for heating an engine coolant; program instructions that determine whether a first condition in which a temperature of the engine coolant is equal or to greater than a first temperature and a second condition in which a driving torque generated by a motor is sufficient to move the hybrid vehicle are satisfied; and program instructions that stop operation of an engine when the first and second conditions are satisfied, by a time that a driving torque generated by the engine is required to move the hybrid vehicle regardless of receiving the engine-drive-requiring signal. - View Dependent Claims (14, 15, 16, 17)
