DRIVING SUPPORT APPARATUS FOR VEHICLE
First Claim
1. A driving support apparatus for a vehicle, comprising:
- a front vehicle detector configured to detect a vehicle in front on a subject vehicle travel path;
an automatic follow-up controller capable of selectively executing as an automatic follow-up control, when the vehicle in front is detected, any of controls including a follow-up cruise control controlling the subject vehicle to follow the vehicle in front that is traveling, a follow-up stop control controlling the subject vehicle to stop as the vehicle in front that stops during the follow-up cruise control, and a stop maintaining control maintaining a stopped state of the subject vehicle that has stopped as a result of the follow-up stop control;
a starting permission determiner configured to permit starting of the subject vehicle from a stopped state when a preset operational input is made by a driver during the stop maintaining control and an inter-vehicle distance to the vehicle in front exceeds a determination threshold before a preset amount of time passes from the operational input; and
a threshold setter configured to calculate a first threshold that is updated to a larger value according to a change in the inter-vehicle distance to the vehicle in front in a stopped state when the inter-vehicle distance changes to a larger value and a second threshold that is changed to a larger value as a speed of the vehicle in front increases, and to variably set the determination threshold based on the larger of the first threshold and the second threshold.

Abstract
A cruise control unit, configured to permit starting when an inter-vehicle distance to a front vehicle exceeds a determination threshold before a preset amount of time passes from a driver'"'"'s operational input during a stopped state, calculates a first threshold that is updated to be larger according to a change in the inter-vehicle distance in the stopped state when the distance changes to be larger and a second threshold that is changed to be larger as a speed of the front vehicle is higher, and variably sets the determination threshold based on the larger of the two thresholds. It cancels the permission if a time passing from the operational input is determined longer than a cancel determination time for determining whether it is immediately after the driver'"'"'s operational input and if the front vehicle is determined to stop or substantially stop at a speed lower than a preset vehicle speed.

4. A driving support apparatus for a vehicle, comprising:
-
a front vehicle detector configured to detect a vehicle in front on a subject vehicle travel path; an automatic follow-up controller capable of selectively executing as an automatic follow-up control, when the vehicle in front is detected, any of controls including a follow-up cruise control controlling the subject vehicle to follow the vehicle in front that is traveling, a follow-up stop control controlling the subject vehicle to stop as the vehicle in front that stops during the follow-up cruise control, and a stop maintaining control maintaining a stopped state of the subject vehicle that has stopped as a result of the follow-up stop control; a starting permission determiner configured to determine starting permission of the subject vehicle from a stopped state when a preset operational input is made by a driver during the stop maintaining control and an inter-vehicle distance to the vehicle in front exceeds a determination threshold before a preset amount of time passes from the operational input; and a canceller configured to cancel the starting permission if a time that has passed from the operational input is determined to be shorter than the preset amount of time and longer than a cancel determination time for determining whether it is immediately after the operational input by the driver and if the vehicle in front is determined to be in a stopped state or in a substantially stopped state at a speed lower than a preset vehicle speed.
