DECELERATION SETTING SYSTEM, DECELERATION SETTING METHOD, AND DECELERATION SETTING PROGRAM
First Claim
1. A deceleration setting system for a vehicle, the system comprising:
- a memory that stores;
a computer-executable deceleration control program; and
map information describing a map;
a processor that, when the deceleration control program is executed;
accesses learning information, the learning information including target deceleration points associated with deceleration end points, each target deceleration point being a point on a road where deceleration of the vehicle must be completed, and each deceleration end point being 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;
acquires from the learning information a target deceleration point in the direction of travel of the vehicle and the deceleration end point associated with the acquired target deceleration point;
based on the map information, determines a distance between the acquired target deceleration point and the acquired deceleration end point;
predicts that the determined distance is a distance over which traffic is present prior to the target deceleration point in the direction of travel of the vehicle; and
communicates 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.

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.

9. A deceleration setting method for a vehicle, the system comprising:
-
accessing, with a processor; map information describing a map; and learning information, the learning information including target deceleration points associated with deceleration end points, each target deceleration point being a point on a road where deceleration of the vehicle must be completed, and each deceleration end point being 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; acquiring from the learning information, with the processor, a target deceleration point in the direction of travel of the vehicle and the deceleration end point associated with the acquired target deceleration point; based on the map information, determining, with the processor, a distance between the acquired target deceleration point and the acquired deceleration end point; predicting, with the processor, that the determined distance is a distance over which traffic is present prior to the target deceleration point in the direction of travel of the vehicle; and causing the processor to 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. - View Dependent Claims (10, 11, 12, 13, 14)
