A preceding vehicle speed estimation unit estimates a preceding vehicle speed after a predetermined period of time based on a preceding vehicle speed and an acceleration of the preceding vehicle, and an ACC target vehicle speed setting unit sets a target vehicle speed for the vehicle following based on an inter-vehicle distance between the vehicle and preceding vehicle and the preceding vehicle speed after a predetermined period of time. Then, during the stop maintaining control, an ACC resetting acceptability determination unit compares the target vehicle speed and a reference threshold. When the target vehicle speed is greater than the reference threshold, it is determined to accept ACC resetting in response to the driver's input operation, and, when the target vehicle speed is equal to or less than the reference threshold, it is determined not to accept ACC resetting. |
