Abstract
Provided is a driving assist system which includes an own vehicle velocity sensor, an adjacent vehicle velocity sensor, and a control device and where the control device makes constant velocity travelling by causing a velocity of an own vehicle to fall within a constant velocity range between a lower limit value and an upper limit value set based on a target velocity and, when the own vehicle travels on a passing lane and an adjacent vehicle travels on a cruising lane, if a relative velocity of the adjacent vehicle to the own vehicle falls within a set range, the control device performs speed-up adjustment to increase the velocity of the own vehicle in a range up to the upper limit value.
Claims6
A driving assist system which is installed in an own vehicle and supports velocity adjustment of the own vehicle in a time when the own vehicle travels on a road provided with two or more lanes including a cruising lane and a passing lane on one side, comprising:
- a relative velocity acquisition device that acquires a relative velocity of an adjacent vehicle, which travels in the same direction as the own vehicle and is ahead of the own vehicle on a lane adjacent to the lane on which the own vehicle travels, with respect to the own vehicle;
- and
- a control device that is connected to the relative velocity acquisition device to adjust the velocity of the own vehicle, wherein
- the control device makes constant velocity travelling by causing the velocity of the own vehicle to fall within a constant velocity range between a lower limit value and an upper limit value set based on a target velocity, and
- when the own vehicle travels on the passing lane and the adjacent vehicle travels on the cruising lane, if the relative velocity acquired by the relative velocity acquisition device falls within a set range set in advance, the control device performs speed-up adjustment to increase the velocity of the own vehicle in a range up to the upper limit value.
A driving assist method which supports velocity adjustment of an own vehicle, comprising:
- when, on a road provided with two or more lanes including a cruising lane and a passing lane on one side, the own vehicle travels on the passing lane with constant velocity travelling where a velocity of the own vehicle falls within a constant velocity range between a lower limit value and an upper limit value set based on a target velocity and an adjacent vehicle travelling in the same direction as the own vehicle and is ahead of the own vehicle travels on the cruising lane,
- acquiring a relative velocity of the adjacent vehicle with respect to the own vehicle;
- determining whether the acquired relative velocity falls within a set range set in advance;
- and
- performing, when it is determined that the acquired relative velocity falls within the set range, velocity adjustment where the velocity of the own vehicle is increased in a range up to the upper limit value to make the relative velocity more negative.
