を特徴とする車両走行制御装置。゛An inter-vehicle distance detection device that detects the inter-vehicle distance between the own vehicle and the preceding vehicle, a vehicle speed detection means that detects the own vehicle speed, a constant speed running command means that starts the own vehicle running at a constant speed, and an operation of the constant speed running command means. When the vehicle speed setting means that sets the vehicle speed based on the detected own vehicle speed, the safe following distance calculation means that calculates the safe following distance according to the set vehicle speed, and the J constant speed driving command means are in operation. Acceleration/deceleration rate control that calculates the acceleration rate or deceleration rate of the own vehicle speed to maintain the set vehicle speed when the distance exceeds the safe inter-vehicle distance, and to adjust the vehicle speed to the set vehicle speed when the inter-vehicle distance is shorter than the safe inter-vehicle distance. a throttle valve opening control means that changes the opening of the throttle valve in accordance with the calculated acceleration rate or deceleration rate; and a means for detecting that the preceding vehicle is no longer within the detection range from the output of the inter-vehicle distance detection device. What is claimed is: 1. A vehicle running control device comprising: a change determination signal; and a vehicle speed maintenance device that instructs an acceleration/deceleration rate control device to maintain the vehicle speed when the change determination signal is input.゛
