METHOD FOR WARNING A FOLLOWING MOTOR VEHICLE
A method is provided for warning a following motor vehicle through a motor vehicle travelling ahead, in which a distance between the motor vehicle travelling ahead and the motor vehicle following is measured and compared with a safety distance, which is dependent on a travelled speed of the motor vehicle travelling ahead and when the measured distance undershoots this safety distance, a warning signal is emitted by the motor vehicle travelling ahead to the following motor vehicle. An apparatus is also provided for warning a following motor vehicle through a motor vehicle travelling ahead.
1 . A method of a first motor vehicle warning a second motor vehicle following the first motor vehicle, comprising:
measuring a distance (A) between the first motor vehicle and the second motor vehicle;
comparing the distance (A) compared a safety distance (S) that is at least dependent on a travelled speed (v) of the first motor vehicle; and
a warning signal (W) by the first motor vehicle when the safety distance (S) is undershot by the distance (A).
2 . The method according to claim 1 , further comprising presetting a connection between the travelled speed (V) and the safety distance (S).
3 . The method according to claim 1 , wherein the warning signal (W) is a visual signal.
4 . (canceled)
5 . A non-transitory computer readable medium embodying a computer program product, said computer program product comprising:
a warning program for a first motor vehicle warning a second motor vehicle following the first motor vehicle, the warning program configured to:
measure a distance (A) between the first motor vehicle and the second motor vehicle;
compare the distance (A) with a safety distance (S) that is at least dependent on a travelled speed (v) of the first motor vehicle; and
a warning signal (W) by the first motor vehicle when the safety distance (S) is undershot by the distance (A).
6 . An apparatus for a first motor vehicle warning a second motor vehicle following the first motor vehicle, comprising:
with a measuring device that is configured to measure a distance (A) between the first motor vehicle and the second motor vehicle;
a comparing device that is configured to compare the distance (A) with a safety distance (S) that is dependent on a travelled speed (v) of the first motor vehicle; and
an emitting device that is configured to emit a warning signal (W) from the first motor vehicle to the second motor vehicle when the safety distance (S) is undershot by the distance (A).
7 . The apparatus according to claim 6 , wherein a connection between the travelled speed (v) and the safety distance (S) is influenced.
8 . The apparatus according to claim 6 , wherein the warning signal (W) comprises a visual.
9 . The apparatus according to claim 8 , wherein the warning signal (W) comprises a light projection onto a road between the first motor vehicle and the second motor vehicle.
10 . The apparatus according to claim 9 , wherein the light projection comprises a warning triangle.
11 . The apparatus according to claim 6 , wherein the measuring device is a rear-end radar.
12 . The method according to claim 1 , wherein the warning signal (W) is an acoustic signal.
13 . The method according to claim 1 , wherein the warning signal (W) is a radio signal.
14 . The non-transitory computer readable medium embodying the computer program product of claim 5 , said warning program further configured to receive a preset connection between the travelled speed (V) and the safety distance (S).
15 . The non-transitory computer readable medium embodying the computer program product of claim 5 , wherein the warning signal (W) is an acoustic signal.
16 . The non-transitory computer readable medium embodying the computer program product of claim 5 , wherein the warning signal (W) is a radio signal.
17 . The non-transitory computer readable medium embodying the computer program product of claim 5 , wherein the warning signal (W) is an acoustic signal.
18 . The apparatus according to claim 6 , wherein the warning signal (W) comprises a radio signal.
19 . The apparatus according to claim 6 , wherein the warning signal (W) comprises an acoustic signal.
20 . The apparatus according to claim 6 , wherein the warning signal (W) comprises an acoustic signal.
