PROBLEM TO BE SOLVED: To suitably perform follow-up travel control without giving a sense of incongruity to a driver even when traveling resistance by road gradient is varied. SOLUTION: An inter-vehicle distance command value L* is calculated based on a preceding vehicle speed Vt by a basic inter-vehicle distance command value calculation part 31 based on an actual inter-vehicle distance L detected by a inter-vehicle distance sensor 1 and an own vehicle speed V detected by a vehicle sensor 2. When the road gradient is uphill, an corrected inter-vehicle distance command value L*' is calculated wherein the inter-vehicle distance command value L* is corrected to be extended based on a road gradient estimated value Sr estimated by a road gradient estimation part 38. A vehicle speed command value V* is calculated based on the corrected inter-vehicle distance command value L*' by a target inter-vehicle distance calculation part 33 and a vehicle speed command value calculation part 34. A driving force command value F* is calculated based on the vehicle speed command value V* by a vehicle speed control part 4. A throttle actuator 5 is controlled based on the driving force command value F*. Thus, follow-up travel control is performed. COPYRIGHT: (C)2004,JPO
