Abstract
A driving support ECU is configured to, when s specific recognition state occurs where a lane marker recognized changes from a left lane marker to a right lane marker or vice versa under a one side lane marker recognizable state, set a steering angle guard value to a second steering angle guard value smaller than a first steering angle guard value and set a steering angle speed guard value to a second steering angle speed guard value smaller than a first steering angle speed guard value.
Claims11
A vehicle traveling support apparatus comprising:
- a sensor for recognizing a lane marker on a traveling lane in which an own vehicle is traveling;
- and
- an electronic control unit configured to perform a lane keeping control to control a steering angle of said own vehicle so as to have said own vehicle travel along a target traveling line set based on at least any one of a left lane marker and a right lane marker recognized by said sensor, said left lane marker being on a left side with respect to said own vehicle, said right lane marker being on a right side with respect to said own vehicle,
- wherein,
- when performing said lane keeping control, said electronic control unit is configured to:
- execute at least any one of:
- (i) a process to control said steering angle so as to match a magnitude of said steering angle with a steering angle guard value when said magnitude of said steering angle exceeds said steering angle guard value;
- and
- (ii) a process to control said steering angle so as to match a magnitude of a steering angle speed which is an amount of change per unit time of said steering angle with a steering angle speed guard value when said magnitude of said steering angle speed exceeds said steering angle speed guard value;
- and
- set, when a recognition state of said lane marker by said sensor is a one side lane marker recognizable state which is a state where said sensor can recognize only one of said left lane marker and said right lane marker, a change amount of said steering angle and/or a change amount of said steering angle speed to a value which is smaller than when said recognition state of said lane marker is a both lane markers recognizable state which is a state where said sensor can recognize both said left lane marker and said right lane marker.

- wherein, when performing said lane keeping control, said electronic control unit is configured to:
- execute at least any one of:
- (i) a process to control said steering angle so that a magnitude of said steering angle set when a change amount in the position of the target traveling line in the lane width direction is relatively large is larger than a magnitude of said steering angle set when a change amount in the position of the target traveling line in the lane width direction is relatively small;
- and
- (ii) a process to control said steering angle so that a magnitude of a steering angle speed which is an amount of change per unit time of said steering angle set when a change amount in the position of the target traveling line in the lane width direction is relatively large is larger than a magnitude of said steering angle speed set when a change amount in the position of the target traveling line in the lane width direction is relatively small;
- and
