Claims

[Scope of utility model registration request]

An inter-vehicle distance detection device for detecting the inter-vehicle distance between the own vehicle and the preceding vehicle, a vehicle speed detection means for detecting the own vehicle speed, a constant speed running command means for starting the own vehicle to run at a constant speed, and a constant speed running command means. When activated, there is a vehicle speed setting means that sets the vehicle speed based on the detected own vehicle speed, and a safe following distance calculation means that calculates a safe following distance according to the set vehicle speed. When the preceding vehicle speed calculating means for calculating the vehicle speed and the constant speed traveling command means are operating, when the inter-vehicle distance exceeds the safe inter-vehicle distance, calculate an acceleration rate or deceleration rate to adjust the own vehicle speed to a set vehicle speed,
When the inter-vehicle distance is shorter than the safe inter-vehicle distance, the system calculates the acceleration or deceleration rate to adjust the own vehicle speed to the vehicle speed corresponding to the inter-vehicle distance, and when it detects that the preceding vehicle speed has exceeded the set vehicle speed, it instructs a constant acceleration rate. 1. A vehicle running control device comprising a speed control means and a throttle valve opening control means for changing the opening of a throttle valve according to a calculated or instructed acceleration rate or deceleration rate.
