Patent ID: 8463522

Claim:
A running control device for a vehicle, comprising: a vehicle speed sensor which detects an actual vehicle speed of the vehicle; a target vehicle speed setting section which sets a target vehicle speed; a target driving force calculation section which calculates a target driving force based on a vehicle speed deviation of the actual vehicle speed detected by the vehicle speed sensor from the target vehicle speed set by the target vehicle speed setting section; a driving force control section which performs driving force control based on the target driving force calculated in the target driving force calculation section; a vehicle speed allowed lowering value setting section which sets an allowed lowering value of the actual vehicle speed with respect to the target vehicle speed; and a target driving force upper limit value calculation section which calculates a target driving force upper limit value based on the actual vehicle speed, wherein in a case where an amount by which the actual vehicle speed is lowered with respect to the target vehicle speed is within the allowed lowering value, the target driving force calculation section restricts the target driving force to be less than or equal to the target driving force upper limit value calculated by the target driving force upper limit value calculation section, and the driving force control section performs driving force control based on the restricted target driving force.
