Patent ID: 8886431

Claim:
A vehicle running control system that, at the time of controlling driving force, determines whether an operating speed that is a speed at which a driver operates an accelerator operator is higher than or equal to a threshold and that changes details of control over the driving force on the basis of a result of the determination, the vehicle running control system comprising: a threshold setting unit that sets the threshold on the basis of operation information, other than the operating speed of the accelerator operator, within information related to operation of the accelerator operator; wherein the operation information is a stroke amount that is an operation amount of the accelerator operator when the driver has operated the accelerator operator, the threshold is set to be larger as the stroke amount increases, and when determined that the operating speed is higher than or equal to the threshold, the details of control over the driving force are changed so that a rate of change of the driving force is increased as compared with a rate of change during normal times.
