Abstract

A method, and associated system and computer program product, for managing braking of a moving vehicle. A speed and deceleration of the moving vehicle are monitored. External and/or internal conditions relating to the moving vehicle and/or the vehicle'"'"'s driver are detected. A hardware processor: calculates a braking distance for the moving vehicle for the detected external and/or internal conditions from the monitored speed and deceleration of the moving vehicle; determines a spacing distance between the moving vehicle and a second vehicle ahead of the moving vehicle; adds a cascading response distance to the calculated braking distance for a third vehicle ahead of the second vehicle; and determines that the calculated braking distance is greater than the determined spacing distance. An output is generated in response to the determination that the calculated braking distance is greater than the obtained spacing distance.

Claims

monitoring a speed and deceleration of the moving vehicle;

detecting one or more external and/or internal conditions relating to the moving vehicle and/or a driver of the moving vehicle;

calculating, by a hardware processor, a braking distance for the moving vehicle for the detected one or more external and/or internal conditions from the monitored speed and deceleration of the moving vehicle;

determining, by the processor, a spacing distance between the moving vehicle and a second vehicle ahead of the moving vehicle;

adding, by the processor, a cascading response distance to the calculated braking distance for a third vehicle ahead of the second vehicle, the cascading response distance calculated from a response distance for the second vehicle relative to the third vehicle;

determining, by the processor, that the calculated braking distance is greater than the determined spacing distance; and

generating an output in response to the determination that the calculated braking distance is greater than the obtained spacing distance.

2. The method of claim 1, wherein the generating an output comprises providing a visual and/or audio warning signal.

4. The method of claim 1, wherein the calculating a braking distance for the moving vehicle for the detected external and/or internal conditions from the monitored speed and deceleration of the moving vehicle comprises determining a minimal response distance for a specific monitored speed and deceleration of the moving vehicle and adding an additional response distance for the specific detected external and/or internal conditions.

5. The method of claim 1, said method further comprising:

determining, by the processor, that one or more vehicles are ahead of the third vehicle and in response, adding, by the processor, respective additional cascading response distances to the calculated braking distance, the additional cascading response distances calculated from response distances for the respective one or more vehicles.

6. A system, comprising a hardware processor, said system configured to perform a method for managing braking of a moving vehicle, said method comprising:

monitoring a speed and deceleration of the moving vehicle;
