Abstract

Responsive to braking, a CPU of a driving assist apparatus calculates an average deceleration of the vehicle and then calculates a braking distance. The CPU further calculates a final position at which the vehicle will come to a stop, on the basis of the braking distance. The CPU next activates an assist display for display a map including, superimposed thereon, the route to the final position and an arrival indicator indicating the stop (final) position of the vehicle.

Claims

1. A driving assist method for assisting a driver in decelerating a vehicle, comprising:

calculating a position at which a vehicle speed will become a predetermined speed based on deceleration of the vehicle; and

displaying the calculated position as an arrival indicator on a road map display.

4. The driving assist method according to claim 1, wherein:

the predetermined speed is 0 kilometers per hour.

5. The driving assist method according to claim 1, wherein:

a plurality of predetermined speeds are set in a memory and arrival indicators indicating positions at which the vehicle speed will become each of the plurality of the predetermined speeds are individually displayed, superimposed on the road map.

6. The driving assist method according to claim 1, further comprising:

detecting an object located in front of the vehicle, specifying the position of the detected object, generating an object indicator indicating the specified position of the object, and displaying the object indicator and the arrival indicator together, superimposed on the road map.

2. A driving assist method for assisting a driver in decelerating a vehicle, comprising:

detecting an object located in front of the vehicle;

specifying the position of the detected object;

calculating a position at which the vehicle speed will become a predetermined speed based on deceleration of the vehicle; and

converting the calculated position to an arrival indicator and displaying the arrival indicator.

3. The driving assist method according to claim 2, wherein:

the predetermined speed is 0 kilometers per hour.

7. The driving assist method according to claim 2 additionally comprising:

generating an object indicator indicating the specified position of the object, and

displaying the object indicator and the arrival indicator together, superimposed on the road map.

8. A driving assist apparatus for assisting a driver in decelerating a vehicle, comprising:

final position calculating means for calculating a position at which a vehicle speed will become a predetermined speed based on vehicle position and deceleration of the vehicle;

display means for displaying a road map; and

display control means for displaying an arrival indicator indicating the calculated position superimposed on the displayed road map.

9. The driving assist apparatus according to claim 8, wherein:

the final position calculating means calculates the position at which the vehicle speed will become the predetermined speed only when braking of the vehicle is detected.

10. The driving assist apparatus according to claim 9, wherein:

the final position calculating means calculates the position at which the vehicle will come to a stop.

11. The driving assist apparatus according to claim 8, wherein:

the final position calculating means calculates the position at which the vehicle will come to a stop.

12. The driving assist apparatus according to claim 8, wherein:

the final position calculating means calculates each position at which the vehicle speed becomes one of a plurality of predetermined speeds; and

the display control means displays individual arrival indicators, respectively indicating the plurality of positions calculated by the final position calculating means, superimposed on the displayed road map.

13. The driving assist apparatus according to claim 9, wherein:

the final position calculating means calculates each position at which the vehicle speed becomes one of a plurality of predetermined speeds; and

the display control means displays individual arrival indicators, respectively indicating the plurality of positions calculated by the final position calculating means, superimposed on the displayed road map.

14. The driving assist apparatus according to claim 8, further comprising:

object position calculating means for calculating the position of an object located in front of the vehicle, wherein the display control means displays an object indicator indicating the calculated position of the object together with the arrival indicator indicating the final position.

15. The driving assist apparatus according to claim 9, further comprising:

object position calculating means for calculating the position of an object located in front of the vehicle, wherein the display control means displays an object indicator indicating the calculated position of the object together with the arrival indicator indicating the final position.

16. A driving assist apparatus for assisting a driver in decelerating a vehicle, comprising:

object position calculating means for calculating the position of an object located in front of the vehicle;

final position calculating means for calculating a position at which vehicle speed will become a predetermined speed based on vehicle position and deceleration of the vehicle;

converting means for converting the calculated position to a value;

display means for displaying a decelerating assist image; and

display control means for displaying the value on the display means.

17. The driving assist apparatus according to claim 16, wherein:

the final position calculating means calculates a position at which a vehicle speed will become a predetermined speed responsive to satisfaction of conditions including braking.
