  • Publication number: 20210101525
    Abstract: A brake lamp control method of a vehicle is provided. The method includes determining whether a deceleration of the vehicle based on regenerative brake through the electric motor is present in a hysteresis period between an off threshold as a reference for turning off a brake lamp and an on threshold as a reference for turning on the brake lamp. When the deceleration of the vehicle is present in the hysteresis period, the method includes determining a state of the brake lamp before the deceleration of the vehicle enters the hysteresis period. In response to determining that the brake lamp is turned on or off for a reason except for the regenerative brake before the deceleration of the vehicle enters the hysteresis period, a request for turning on the brake lamp is set or reset based on the regenerative brake in response to the determined state of the brake lamp.

  • Publication number: 20160121898
    Abstract: A method of controlling coasting operation of a hybrid vehicle during a coasting operation and an apparatus for performing the same are provided. The coasting operation is controlled by calculating a remaining distance from a current location of a vehicle and a location at a target vehicle speed and an approach distance until reaching the target vehicle speed demanded at a current vehicle speed. Additionally, an inertia torque is adjusted to correspond to vehicle variation based on roads, slopes of the roads, and exterior disturbances. Thus, since inertia torque is adjusted during the coasting operation based on the target vehicle speed, unnecessary energy loss is reduced and fuel ratio is enhanced during traveling on roads.
