Abstract
Deceleration control systems, methods, and programs acquire from learning information a target deceleration point in front of a traveling vehicle and an associated deceleration end point. The deceleration end point is a point representative of one or more locations at which deceleration of the vehicle or another vehicle was actually completed in the past as the vehicle or the other vehicle approached the associated deceleration end point. The systems, methods, and programs determine a distance between the acquired target deceleration point and the acquired deceleration end point as a predicted distance over which traffic is present. The systems, methods, and programs communicate with a vehicle ECU to perform a deceleration control of the vehicle so that (i) the longer the determined distance, the greater the deceleration rate applied during the deceleration control, and (ii) the deceleration is complete by the time the vehicle reaches the acquired deceleration end point.
