Claims

[Scope of utility model registration request]

An inter-vehicle distance detection device that detects the inter-vehicle distance between the own vehicle and a preceding vehicle, a vehicle speed detection means that detects the own vehicle speed, a constant speed driving command means that causes the own vehicle to start and maintain constant speed driving, and a constant speed driving command means. , a vehicle speed setting means for setting the vehicle speed based on the detected own vehicle speed, a safe following distance calculation means for calculating a safe following distance according to the set vehicle speed, and a vehicle speed setting means for setting the vehicle speed based on the detected own vehicle speed, and a safe following distance calculation means for calculating the safe following distance according to the set vehicle speed, and A reference vehicle speed setting means for setting a reference vehicle speed range by setting a limit and further setting a reference speed lower by a predetermined speed than the lower limit of the reference vehicle speed range, and a constant speed driving command means are operating, when the inter-vehicle distance is within a safe distance. A vehicle speed calculation means that outputs a set vehicle speed when the distance exceeds the distance, and calculates and outputs a vehicle speed corresponding to the following distance when the inter-vehicle distance is shorter than the safe inter-vehicle distance; If the vehicle speed is within or below the reference speed range, an acceleration rate or deceleration rate is calculated to adjust the own vehicle speed to the output vehicle speed, and if the vehicle speed is output from the vehicle speed calculation means or exceeds the upper limit of the reference vehicle speed range, the own vehicle speed is adjusted to the output vehicle speed. acceleration/deceleration rate control means for calculating an acceleration rate or deceleration rate to adjust the own vehicle speed to the lower limit vehicle speed when the vehicle speed is lower than the lower limit of the reference vehicle speed range and higher than the reference speed; 1. A vehicle running control device comprising a throttle valve opening degree control means for changing the opening degree of the throttle valve.
