PROBLEM TO BE SOLVED: To realize a smooth travel so as to give an impression of a vehicle travelling on a level road even in a case where constant-speed travel control is started immediately after transition from a level road to a down-hill and the like.SOLUTION: A standard vehicle model 10 includes: a rolling-resistance component storage part 10a; and an air resistance component setup part 10b. A rolling-resistance component R1 and an air resistance component R2 are supplied to selection parts 10c, 10d, which output the rolling-resistance component R1 and the air resistance component R2 if a flag Fa is in a non-set state, or output "0" if the flag Fa is in a set state. An adder 10f adds an estimation value and the output of the selection parts 10c,10d, and a divider 10g divides the result of the aforementioned addition by a mass M of a vehicle to calculate a standard acceleration Gc. The standard acceleration Gc is integrated to calculate a standard vehicle speed Vc. Then control is performed so that an actual speed matches the standard acceleration Gc both in the normal travel and under the constant speed travel control. |
