HYBRID ELECTRIC VEHICLE
DRIVE
June 19, 2025
Hybrid electric vehicle includes a control device that switches between hybrid-type driving and motor-type driving. The control device includes a setting unit configured to set a determination value based on a predicted upper limit value which is a predicted value of an output upper limit value of a battery when the start of the engine is completed during the running of the motor during the hybrid running. The setting unit sets, as the determination value, a vehicle speed at which a sufficient output value, which is a value obtained by adding a predetermined margin value to a necessary output value, becomes the predicted upper limit value. The required output value is an output value per unit time of the battery for each vehicle speed that can be maintained by the motor when starting of the engine is completed. The margin value decreases as the vehicle speed decreases.
