TLDR
In this paper, the authors propose an automatic brake control device of a vehicle capable of achieving an automatic braking control without giving an uncomfortable feeling to a driver regardless of a stop position approaching path, on which the vehicle is now traveling.Abstract:
PROBLEM TO BE SOLVED: To provide an automatic brake control device of a vehicle capable of achieving an automatic brake control without giving an uncomfortable feeling to a driver regardless of a stop position approaching path, on which the vehicle travels. SOLUTION: This device starts automatic brake control when a distance between a current point and a temporary stop point obtained from a navigation device becomes not more than a final required braking distance Lth x Klth. At that time, a final required deceleration change pattern, Pattfin(x) to be a target to follow control an actual deceleration of the vehicle is produced. The final required deceleration change pattern, Pattfin (x) is produced on the basis of a reference average deceleration change pattern, Pattnormave (J) corresponding to a stop position approaching path J, on which the vehicle is now traveling, among each of reference average deceleration change patterns respectively stored/learnt in a backup RAM every stop position approaching path in advance based on the actual braking operation by the driver.

Brake control device
Katsuya Iwasaki,Keigo Kajiyama +1 more
TL;DR: In this article, when the control pressure detected by a control pressure sensor becomes smaller than a switching determination threshold value, the brake ECU determines that an operation of returning a brake pedal is being performed and switches the braking mode from the depression force fluid pressure mode to a normal control mode.

Navigation device for vehicle
Kazumasa Nakamura,和正 中村 +1 more
TL;DR: In this paper, a navigation ECU (Electronical Control Unit) after extracting temporary stop place data stored in a map data base finds the distance between the current position of the vehicle and a temporary stop point closest to the position and judges whether or not the found distance is 300 m (Sa4).
