Abstract
When the object detection unit 10 detects the front vehicle X, the speed of the own vehicle 2 is controlled using a detection value of the state of the front vehicle (position, speed) detected by the front vehicle state detection unit 15, and, in the lost state where the front vehicle X is not detected, the speed of the own vehicle 2 is controlled using an estimation value of the state of the front vehicle by the lost front-vehicle state estimation unit 22 based on a condition that a length of the scheduled traveling route of the own vehicle 2 is shorter than a predetermined threshold in the detection target range by the object detection unit 10 as a necessary condition.
Claims6
A cruise controller installed in a vehicle as an own vehicle that performs cruise control of the own vehicle so as to follow a front vehicle traveling ahead of the own vehicle, comprising:
- an object detection unit configured to detect, in a predetermined detection target range on a front side of the own vehicle, the front vehicle existing in the predetermined detection target range;
- a front vehicle state detection unit configured to detect a state of the front vehicle, including at least any one of a position or a speed of the front vehicle that is detected by the object detection unit;
- a lost front-vehicle state estimation unit configured to, when a lost state occurs where the front vehicle detected by the object detection unit is not detected, estimate a state of the front vehicle in the lost state;
- a route-length determination unit configured to determine whether or not a length of a scheduled traveling route of the own vehicle in the detection target range is shorter than a predetermined threshold;
- and
- a speed control unit configured to control a speed of the own vehicle so as to follow the front vehicle, wherein
- the speed control unit is configured to, when the object detection unit detects the front vehicle, control the speed of the own vehicle using a detection value of the state of the front vehicle detected by the front vehicle state detection unit, and to, in the lost state, control the speed of the own vehicle using an estimation value of the state of the front vehicle by the lost front-vehicle state estimation unit based on a positive determination result by the route-length determination unit as a necessary condition.
