Driving control apparatus
First Claim
1. A driving control apparatus comprising:
- a vehicle speed detecting unit that detects a traveling speed of a vehicle;
a follow-up control request detecting unit that detects an operation by a driver requesting a follow-up control;
an object detecting unit that is installed in the vehicle and detects objects that are present in a direction in which the vehicle travels;
a preceding vehicle determining unit that determines a preceding vehicle in front of the vehicle and among the detected objects;
a target inter-vehicle distance determining unit that determines a target inter-vehicle distance between the vehicle and the preceding vehicle;
a target vehicle speed determining unit that determines a target vehicle speed of the vehicle based on a signal from the object detecting unit and the determined target inter-vehicle distance; and
a follow-up control unit that controls a follow-up control based on the determined target vehicle speed and the traveling speed of the vehicle,wherein the follow-up control unit, when the operation by the driver requesting the follow-up control is detected while the vehicle is traveling at a speed equal to or higher than a first predetermined vehicle speed, executes an adaptive cruise control in which the vehicle is made to travel at a speed higher than a second predetermined vehicle speed that is lower than the first predetermined vehicle speed, andwherein the follow-up control unit, when the operation by the driver requesting the follow-up control is detected while the vehicle is traveling at a speed equal to or lower than a third predetermined vehicle speed that is lower than the first predetermined vehicle speed, executes a low-speed following control in which the vehicle is made to travel or stop while following the preceding vehicle.

Abstract
Systems and apparatuses are provided for controlling the speed of a driver'"'"'s vehicle either in a first adaptive cruise control mode or a second travel or stop mode. In one embodiment, there is provided an apparatus comprising a speed control unit that executes a follow-up control based at least in part on a target inter-vehicle distance between the driver'"'"'s vehicle and a preceding vehicle (i.e., another vehicle in front of the driver'"'"'s vehicle). The speed control unit executes adaptive cruise control when the driver requests the follow-up control while traveling at a speed equal to or higher than a first predetermined vehicle speed. The control unit executes stop-or-travel control when the driver requests the follow-up control while traveling at a speed equal to or lower than another predetermined vehicle speed lower than the first predetermined vehicle speed.

7. A driving control apparatus comprising:
-
a vehicle speed detecting unit that detects a traveling speed of a vehicle; a follow-up control request detecting unit that detects an operation by a driver requesting a follow-up control; an object detecting unit that is installed in the vehicle and detects objects that are present in a direction in which the vehicle travels; a preceding vehicle determining unit that determines a preceding vehicle in front of the vehicle and among the detected objects; a target inter-vehicle distance determining unit that determines a target inter-vehicle distance between the vehicle and the preceding vehicle; a target vehicle speed determining unit that determines a target vehicle speed of the vehicle based on a signal from the object detecting unit and the determined target inter-vehicle distance; and a follow-up control unit that controls a follow-up control based on the determined target vehicle speed and the traveling speed of the vehicle, wherein the follow-up control unit, when the operation by the driver requesting the follow-up control is detected while the vehicle is traveling at a speed equal to or higher than a first predetermined vehicle speed, executes an adaptive cruise control in which the vehicle is made to travel at a speed equal to or higher than a second predetermined vehicle speed that is lower than the first predetermined vehicle speed, and wherein the follow-up control unit, when the operation by the driver requesting the follow-up control is detected while the vehicle is traveling at a speed equal to or lower than a third predetermined vehicle speed that is lower than the first predetermined vehicle speed, executes a low-speed following control in which the vehicle is made to travel or stop while following the preceding vehicle, the vehicle traveling at a speed equal to or lower than a fourth predetermined vehicle speed that is higher than a third predetermined vehicle speed. - View Dependent Claims (8, 9)
