こと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. At the same time, a vehicle speed setting means for setting the vehicle speed based on the detected own vehicle speed, a safe following distance calculating means for calculating a safe following distance according to the set vehicle speed, and based on the detection outputs of the following distance detecting device and the vehicle speed detecting means. a preceding vehicle speed calculation means for calculating the preceding vehicle speed; a deceleration calculating means for calculating the average deceleration when the throttle valve opening degree is changed from the detected own vehicle speed to the opening degree corresponding to the preceding vehicle speed; When the deceleration start distance calculation means for calculating the inter-vehicle distance at which deceleration starts based on the speed and the constant speed running command means are operating,
When the following distance exceeds the deceleration starting distance, or when the following distance exceeds the safe following distance, the system calculates the acceleration rate or deceleration rate to adjust the own vehicle speed to the set vehicle speed, and the following distance becomes shorter than the deceleration starting distance. Sometimes, it instructs the opening of the throttle valve corresponding to the speed of the preceding vehicle, and furthermore, when the following distance is shorter than the safe following distance, it calculates the acceleration, rate, or deceleration rate to adjust the own vehicle speed to the speed corresponding to the following distance. A vehicle running control device comprising a speed control means and a throttle valve opening degree control means for changing the opening degree of the throttle valve according to a calculated acceleration rate or deceleration rate or a commanded opening degree.
