Abstract
A driving support apparatus is configured to execute, as a deviation control, at least one of a deviation waring for informing a driver of a host vehicle that the host vehicle deviates from a travel area and a vehicle control for controlling a travel state of the host vehicle so that the host vehicle does not deviate from the travel area. The driving support apparatus is configured to suspend or terminate the deviation control when an override condition is satisfied while the deviation control is being executed, and make the override condition more difficult to be satisfied when there is a rear approaching vehicle in the travel area than when there is no rear approaching vehicle in the travel area.
Claims20
A driving support apparatus configured to execute, as a deviation control, at least one of (i) a deviation warning to a driver of a host vehicle that the host vehicle deviates from a host lane in which the host vehicle is traveling and (ii) a vehicle control for controlling a travel state of the host vehicle, when there is a possibility that the host vehicle may deviate from the host lane or when the host vehicle deviates from the host lane,
- wherein,
- the driving support apparatus is configured to:
- suspend or terminate the deviation control when an override condition is satisfied while the deviation control is being executed, the override condition being a condition that is satisfied when a steering index value related to a steering operation performed by the driver is equal or greater than a threshold;
- and
- make the override condition more difficult to be satisfied when there is a rear approaching vehicle in the host lane than when there is no rear approaching vehicle in the host lane, the rear approaching vehicle being a vehicle approaching the host vehicle from a rear of the host vehicle.
A driving support method executed by a computer installed on a host vehicle to execute, as a deviation control, at least one of:
- (i) a deviation warning to a driver of the host vehicle that the host vehicle deviates from a host lane in which the host vehicle is traveling and (ii) a vehicle control for controlling a travel state of the host vehicle, when there is a possibility that the host vehicle may deviate from the host lane or when the host vehicle deviates from the host lane, comprising:
- a first step of suspending or terminating the deviation control when an override condition is satisfied while the deviation control is being executed, the override condition being a condition that is satisfied when a steering index value related to a steering operation performed by the driver is equal or greater than a threshold;
- and
- a second step of making the override condition more difficult to be satisfied when there is a rear approaching vehicle in the host lane than when there is no rear approaching vehicle in the host lane, the rear approaching vehicle being a vehicle approaching the host vehicle from a rear of the host vehicle.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute, as a deviation control, at least one of (i) a deviation warning to a driver of the host vehicle that the host vehicle deviates from a host lane in which the host vehicle is traveling and (ii) a vehicle control for controlling a travel state of the host vehicle, when there is a possibility that the host vehicle may deviate from the host lane or when the host vehicle deviates from the host lane, the program causing the computer to implement processes of:
- suspending or terminating the deviation control when an override condition is satisfied while the deviation control is being executed, the override condition being a condition that is satisfied when a steering index value related to a steering operation performed by the driver is equal or greater than a threshold;
- and
- making the override condition more difficult to be satisfied when there is a rear approaching vehicle in the host lane than when there is no rear approaching vehicle in the host lane, the rear approaching vehicle being a vehicle approaching the host vehicle from a rear of the host vehicle.
