Abstract
An apparatus for controlling a hybrid vehicle and a method thereof are provided. The apparatus includes a hybrid starter & generator (HSG) controller that determines whether an HSG has failed, and a hybrid vehicle controller that controls reverse drive by controlling locking up an engine clutch and maintaining a main relay of a battery to be continuously turned on, based on whether a request for the reverse drive is input from a user. The hybrid vehicle controller changes and applies a vehicle torque control calculation method based on a state of charge (SoC) of the battery, when the HSG has failed.
Claims19
An apparatus for controlling a hybrid vehicle having no reverse gear inside a transmission, the apparatus comprising:
- a hybrid starter & generator (HSG) controller configured to determine whether an HSG has failed;
- and
- a hybrid vehicle controller configured to:
- perform reverse drive control by controlling locking up an engine clutch and maintaining a main relay of a battery continuously in a turned on state, based on whether a request for the reverse drive is input from a user, and change and apply a vehicle torque control calculation method based on a state of charge (SoC) of the battery, in response to determining that the HSG has failed.
A method for controlling a hybrid vehicle having no reverse gear inside a transmission, the method comprising:
- determining, by a controller, whether a hybrid starter & generator (HSG) has failed;
- controlling, by the controller, locking up an engine clutch, based on whether a request for reverse drive is input from a user, in response to determining that the HSG has failed;
- performing, by the controller, reverse drive control by maintaining a main relay of a battery continuously in a turned on state, in response to receiving the request for the reverse drive;
- performing, by the controller, forward control when the input of the request for the reverse drive is released;
- and
- changing and applying, by the controller, a vehicle torque control calculation method based on a state of charge (SoC) of the battery.
