  • Patent number: 9920731
    Abstract: A method for restart when Start-Stop Coasting (SSC) is released may include: determining whether a traveling vehicle satisfies a condition for releasing SSC after entry into SSC (S100); determining whether emergency startup of the vehicle is required (S200) when the traveling vehicle satisfies the condition for releasing SSC after entry into SSC; and performing a first startup process (S300) in which a clutch (420) is engaged along with an operation of a starter motor (430) when the emergency startup of the vehicle is required.

  • Patent number: 9739369
    Abstract: A method for selecting a gear when Start-Stop Coasting (SSC) is released may include: determining whether a traveling vehicle satisfies a condition for releasing SSC after entry into SSC (S100); selecting a gear input to a transmission (S200) when the traveling vehicle satisfies the condition for releasing SSC after entry into SSC; determining a road gradient (S300) when the traveling vehicle satisfies the condition for releasing SSC after entry into SSC; and correcting the selected gear according to a pre-stored correction map so as to correspond to the determined road gradient.

  • Patent number: 9694820
    Abstract: A SSC control method includes a condition satisfaction determination step of determining whether a vehicle can coast and a navigation information acquisition step of obtaining forward road information regarding a road section ahead of a current vehicle position when it is determined, in the condition satisfaction determination step, that the vehicle can coast. The method further includes a forward quick turn section determination step of determining whether a quick turn section exists in the road section ahead by using the forward road information obtained in the navigation information acquisition step, and an SSC entry step of controlling the vehicle to coast when it is determined in the forward quick turn section determination step that the quick turn section does not exist in the road section ahead.

  • Publication number: 20160325749
    Abstract: A method for controlling entry into a SSC based on a change of a road gradient is provided. The method includes determining whether a traveling vehicle satisfies a predetermined condition of entry into the SSC, a road gradient when the vehicle satisfies the predetermined condition of entry into SSC, and whether the determined road gradient satisfies a predetermined condition of road gradient. The change of road gradient is measured when the determined road gradient satisfies the predetermined condition of road gradient. Additionally, the method includes determining whether the measured change of road gradient satisfies a predetermined condition of change of road gradient and entering SSC when the measured change of road gradient satisfies the predetermined condition of change of road gradient.
