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 vehicle that is traveling in front of the vehicle and followed by that vehicle among the objects detected by the object detecting unit;
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 target inter-vehicle distance determined; and
a follow-up control unit that controls a follow-up control on the preceding vehicle 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, and 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 following the preceding vehicle.

Abstract
A driving control apparatus of a vehicle includes a follow-up control unit that controls a follow-up control on a preceding vehicle, wherein the follow-up control unit, when an 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, and 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 following the preceding vehicle.
