Abstract
Official abstract text for this publication.
A vehicle control apparatus includes an electric control unit that performs a preceding vehicle trailing control which makes an own vehicle trail a preceding vehicle as an adaptive cruise control, and performs a first brake control which automatically applies a first braking control to the own vehicle when a time-to-collision to a target object is less than a first threshold. In a case where a performing condition for the first brake control has been determined to be satisfied during a performance of the adaptive cruise control, the electric control unit continues performing the adaptive cruise control without performing the first brake control when a deceleration control by the adaptive cruise control is being performed, whereas stops performing the adaptive cruise control when the deceleration control by the adaptive cruise control is not being performed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle control apparatus applied to an own vehicle comprising: an electric control unit configured to: perform, as an adaptive cruise control, a preceding vehicle trailing control which makes said own vehicle trail a preceding vehicle which is a vehicle traveling ahead of said own vehicle by performing an acceleration control for accelerating said own vehicle and a deceleration control for decelerating said own vehicle so that an acceleration of said own vehicle coincides with a target acceleration, said target acceleration being calculated based on a distance to said preceding vehicle and a relative speed with respect to said preceding vehicle; and perform a pre-crash brake control which automatically applies a predetermined braking force to said own vehicle when a collision risk satisfies a predetermined condition, wherein the electric control unit is further configured to determine, during a performance of said adaptive cruise control, which one of said adaptive cruise control or said pre-crash brake control to perform based on the collision risk and a control status of said adaptive cruise control. 2. The vehicle control apparatus according to claim 1 , wherein, said electric control unit is configured to: perform said pre-crash brake control in preference to said adaptive cruise control despite the control status of said adaptive cruise control when a first condition is determined to be satisfied, the first condition being satisfied when the collision risk is relatively high. 3. The vehicle control apparatus according to claim 1 , wherein, said electric control unit is configured to: determine whether or not to perform said pre-crash brake control in preference to said adaptive cruise control based on the control status of said adaptive cruise control when a second condition is determined to be satisfied, the second condition being satisfied when the collision risk is relatively low. 4. The vehicle control apparatus according to claim 3 , wherein, said electric control unit is configured to perform said adaptive cruise control in preference to said pre-crash brake control when the control status of said adaptive cruise control is said deceleration control in a case in which the second condition is determined to be satisfied. 5. The vehicle control apparatus according to claim 3 , wherein, said electric control unit is configured to: perform said pre-crash brake control in preference to said adaptive cruise control when the control status of said adaptive cruise control is said acceleration control in a case in which the second condition is determined to be satisfied. 6. A vehicle control apparatus applied to an own vehicle comprising an electronic control unit configured top: perform, as an adaptive cruise control, a preceding vehicle trailing control which makes said own vehicle trail a preceding vehicle which is a vehicle traveling ahead of said own vehicle by performing an acceleration control for accelerating said own vehicle and a deceleration control for decelerating said own vehicle so that an acceleration of said own vehicle coincides with a target acceleration, said target acceleration being calculated based on a distance to said preceding vehicle and a relative speed with respect to said preceding vehicle; and perform a pre-crash brake control which automatically applies a predetermined braking force to said own vehicle when a collision risk satisfies a predetermined condition; wherein the electronic control unit is further configured to determine, when said adaptive cruise control is stopped and said pre-crash brake control is started during a performance of said adaptive cruise control, whether or not to automatically resume said adaptive cruise control after the performance of said pre-crash brake control based on the collision risk and a control status of said adaptive cruise control. 7. The vehicle control apparatus according to claim 6 , wherein said electronic control unit is configured not to automatically resume said adaptive cruise control after the performance of said pre-crash brake control despite the control status of said adaptive cruise control when a first condition is determined to be satisfied, the first condition being satisfied when the collision risk is relatively high. 8. The vehicle control apparatus according to claim 6 , wherein, said electronic control unit is configured to: determine whether or not to automatically resume said adaptive cruise control after the performance of said pre-crash brake control based on the control status of said adaptive cruise control which has been performed before said pre-crash brake control is started when a second condition is determined to be satisfied, the second condition being satisfied when the collision risk is relatively low. 9. The vehicle control apparatus according to claim 8 , wherein, said electronic control unit is configured to automatically resume said adaptive cruise control after the performance of said pre-crash brake control when the control status of said adaptive cruise control is said deceleration control in a case in which the second condition is determined to be satisfied. 10. The vehicle control apparatus according to claim 8 , wherein, said electronic control unit is configured not to automatically resume said adaptive cruise control after the performance of said pre-crash brake control when the control status of said adaptive cruise control is said acceleration control in a case in which the second condition is determined to be satisfied.
