To provide a control method for energy saving deceleration using kinetic energy of a vehicle to the maximum for deceleration travelling consisting mainly of coasting travelling.

Problems in execution of energy saving deceleration travelling consisting mainly of coasting travelling in vehicle deceleration are solved as below. (1) For maximizing range capable of coasting travelling, a lower limit speed for coasting travelling (starting speed for braking travelling) and setting of braking travelling distance is set. (2) For complexity of calculation for capable range of coasting travelling, a tentative value for capable range of coasting travelling is set. (3) A braking starting speed for a difference between the tentative value for capable range for coasting travelling and a true value is changed, or a travelling at constant speed at the starting speed for braking travelling is corrected. A learning of the tentative value for capable range for coasting travelling is updated.
