Abstract

The disclosure relates to a method for providing an alert to a driver of a vehicle. The method may comprise a) receiving information from a vehicle-to-vehicle communication unit relating to a deceleration of a vehicle-in-front; b) detecting a decrease in distance to a closest vehicle-in-front by a vehicle sensor system in the vehicle; and c) issuing an alert to the driver of the vehicle as a response to step b.

Claims

1. A method for providing an alert to a driver of a vehicle, the method comprising:

a) receiving information from a vehicle-to-vehicle communication unit relating to a deceleration of a vehicle-in-front;

b) detecting a decrease in distance to a closest vehicle-in-front by a vehicle sensor system in the vehicle;

c) issuing an alert to the driver of the vehicle as a response to step b.

2. The method according to claim 1 wherein the vehicle sensor system detects a deceleration of the closest vehicle-in-front.

3. The method according to claim 1 wherein in step c) the alert to the driver is to brake.

4. The method according to claim 1 wherein the alert is issued as a visual, tactile and/or audible alert.

5. The method according to claim 1 wherein if in step b) a detected decrease in distance to the closest vehicle-in-front exceeds a threshold value, the issuing of the alert in step c) is made with a higher degree of enforcement than for a detected decrease in distance to the closest vehicle-in-front below the threshold value.

6. The method according to claim 1 wherein the vehicle-to-vehicle communication unit is configured to provide the information over a cell network, cloud and/or an automotive Wi-Fi.

7. The method according to claim 1 wherein the vehicle sensor system comprises a camera, video system, radar system and/or LIDAR system.

8. An alert system for a vehicle, the system comprising:

a vehicle-to-vehicle communication unit configured to receive information relating to deceleration of a vehicle-in-front;

a vehicle sensor system configured to detect a decrease in distance to a closest vehicle-in-front; and

a managing unit configured to receive information from the vehicle-to-vehicle communication unit relating to deceleration of a vehicle-in-front and, when the vehicle sensor system detects a decrease in distance to the closest vehicle-in-front, to issue an alert to a driver of the vehicle.

9. A vehicle comprising an alert system according to claim 8.

11. A vehicle comprising an alert system according to claim 9.

10. An alert system for a vehicle for use with a vehicle-to-vehicle communication unit configured to receive information relating to deceleration of a vehicle-in-front, the system comprising:

a vehicle sensor system configured to detect a decrease in distance to a closest vehicle-in-front; and

a managing unit configured to receive information from the vehicle-to-vehicle communication unit relating to deceleration of a vehicle-in-front and, when the vehicle sensor system detects a decrease in distance to the closest vehicle-in-front, to issue an alert to a driver of the vehicle.
