Abstract
An alarm device generates an alarm when a distance between a vehicle and an object that exists in a set region in front of the vehicle is smaller than a set distance. A controller of the alarm device determines a tentative set distance based on at least one of a running speed of the vehicle and a relative velocity between the vehicle and the object, and then corrects the tentative set distance based on at least a deceleration of the vehicle, so as to determine a final set distance.
Claims19
An alarm device that generates an alarm when a distance between a vehicle and an object that exists in a set region in front of the vehicle is smaller than a set distance, comprising a controller that:
- determines a tentative set distance based on at least one of a running speed of the vehicle and a relative velocity between the vehicle and the object;
- determines a relative running deceleration between the vehicle and the object based on a change in a relative position between the vehicle and the object;
- and
- corrects the determined tentative set distance, based on at least one of a running deceleration condition of the vehicle and the relative running deceleration between the object and the vehicle, so as to determine a final set distance.

- determines a tentative set distance based on at least one of a running speed of the vehicle and a relative velocity between the vehicle and the object;
- determines a relative running deceleration between the vehicle and the object based on a change in a relative position between the vehicle and the object;

An alarm device that generates an alarm when a distance between a vehicle and an object that exists in a set region in front of the vehicle is smaller than a set distance, comprising:
- a controller that determines a relative running deceleration between the vehicle and the object based on a change in a relative position between the vehicle and the object, and the set distance based on (a) at least one of a running speed of the vehicle and a relative velocity between the vehicle and the object, (b) a running deceleration of the vehicle, and (c) the relative running deceleration between the vehicle and the object.
An alarm device that generates an alarm when a distance between a vehicle and an object that exists in a set region in front of the vehicle is smaller than a set distance, comprising:
- a controller that determines a relative running deceleration between the vehicle and the object based on a change in a relative position between the vehicle and the object, and the set distance based on (a) at least one of a running speed of the vehicle and a relative velocity between the vehicle and the object, and (b) the relative running deceleration between the vehicle and the object.
An alarm device that generates an alarm when a relative positional relationship between a vehicle and an object that exists in a set region in front of the vehicle represents a tendency of the vehicle to approach the object as compared with a set relative positional relationship, comprising a controller that:
- determines a tentative set relative positional relationship based on at least one of a running speed of the vehicle and a relative velocity between the vehicle and the object;
- and
- corrects the determined tentative set relative positional relationship, based on at least one of a running deceleration of the vehicle and a relative running deceleration between the vehicle and the object, so as to determine a final set relative positional relationship.
