Abstract
A sailing stop control method for a vehicle including a transmission and a friction engaging element in series between an engine and drive wheels includes performing a sailing stop control to coast by shutting off power transmission by the friction engaging element, stopping the engine based on satisfaction of a sailing enter condition, restarting the engine upon satisfaction of a sailing exit condition during coasting by the sailing stop control, executing a shift control to set a target speed ratio of the transmission to a highest speed ratio smaller than a coasting speed ratio in normal time and satisfying engine exhaust performance after the restart of the engine if the sailing exit condition is a brake pedal depressing operation, and re-engaging the friction engaging element, if input and output revolution speeds of the friction engaging element are determined to be a synchronous revolution speed after end of the shift control.
