Abstract
A control method of a hybrid vehicle includes determining, by a controller, whether a target maintaining SOC has been set to a maximum level in a battery maintaining driving mode, determining, by the controller, whether a vehicle speed is equal to or higher than a predetermined speed, when the target maintaining SOC determined is a maximum level, calculating, by the controller, an estimated recovery energy which can be recovered by regenerative braking of the vehicle when a current vehicle speed is equal to or higher than the predetermined speed, and updating, by the controller, the target maintaining SOC by subtracting a subtraction SOC equivalent to the estimated recovery energy calculated from the target maintaining SOC.
Claims4
A control method of a hybrid vehicle, the control method comprising:
- a target level determining operation of determining, by a controller, whether a target state of charge (target SOC) has been set to a maximum level;
- a middle/high speed determining operation of determining, by the controller, whether a current speed of the vehicle is equal to or higher than a first predetermined vehicle speed, when the target SOC is set to the maximum level;
- an energy estimating operation of calculating, by the controller, an estimated recovery energy which can be recovered by regenerative braking of the vehicle when the current speed of the vehicle is equal to or higher than the first predetermined vehicle speed;
- and
- a first state of charge (SOC) correcting operation of updating, by the controller, the target SOC by subtracting a subtraction value equivalent to the estimated recovery energy from the target maintaining SOC,
- wherein the controller manages charging and discharging of the battery according to the updated target SOC.
