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.

First claim

What is claimed is:

1. A method for managing braking of a moving vehicle to avoid a collision by the moving vehicle, said method comprising:
monitoring, by a sensor, a speed and deceleration of the moving vehicle, wherein the moving vehicle comprises a system that includes a hardware processor, the sensor, a detector, and an output device;
detecting, by the detector, one or more conditions relating to the moving vehicle, a driver of the moving vehicle, or both the moving vehicle and the driver of the moving vehicle, wherein each condition of the one or more conditions is independently an external condition or an internal condition;
calculating, by the processor, a braking distance for the moving vehicle for the detected one or more 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;
after said adding, determining, by the processor, that the calculated braking distance is greater than the determined spacing distance; and
in response to the determination that the calculated braking distance is greater than the obtained spacing distance, said output device providing to the driver one or more warning signals to avoid a collision between the moving vehicle and the second vehicle, wherein the one or more warning signals comprise a visual warning signal, an audio warning signal, or both the visual warning signal and the audio warning signal.

2. The method of claim 1 , wherein said detecting one or more conditions comprises detecting current road conditions, weather conditions, or both road conditions and weather conditions.

3. The method of claim 1 , wherein said calculating the braking distance 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 one or more conditions.

4. 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.

5. A system, comprising:
a hardware processor;
a sensor;
a detector; and
an output device,
said system configured to perform a method for managing braking of a moving vehicle to avoid a collision by the moving vehicle, said method comprising:
monitoring, by the sensor, a speed and deceleration of a moving vehicle, wherein the moving vehicle comprises the system;
detecting, by the detector, one or more conditions relating to the moving vehicle, a driver of the moving vehicle, or both the moving vehicle and the driver of the moving vehicle, wherein each condition of the one or more conditions is independently an external condition or an internal condition;
calculating, by the processor, a braking distance for the moving vehicle for the detected one or more 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;
after said adding, determining, by the processor, that the calculated braking distance is greater than the determined spacing distance; and
in response to the determination that the calculated braking distance is greater than the obtained spacing distance, said output device providing to the driver one or more warning signals to avoid a collision between the moving vehicle and the second vehicle, wherein the one or more warning signals comprise a visual warning signal, an audio warning signal, or both the visual warning signal and the audio warning signal.

6. The system of claim 5 , wherein said detecting one or more conditions comprises detecting current road conditions, weather conditions, or both road conditions and weather conditions.

7. The system of claim 5 , wherein said calculating the braking distance 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 one or more conditions.

8. The system of claim 5 , 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 vehicles.

9. A computer program product, comprising a computer readable storage device having computer readable program code stored therein, said program code containing instructions executable by a hardware processor to implement a method for managing braking of a moving vehicle to avoid a collision by the moving vehicle, said method comprising:
monitoring, by a sensor, a speed and deceleration of the moving vehicle, wherein the moving vehicle comprises a system that includes the hardware processor, the sensor, a detector, and an output device;
detecting, by the detector, one or more conditions relating to the moving vehicle, a driver of the moving vehicle, or both the moving vehicle and the driver of the moving vehicle, wherein each condition of the one or more conditions is independently an external condition or an internal condition;
calculating, by the processor, a braking distance for the moving vehicle for the detected one or more 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;
after said adding, determining, by the processor, that the calculated braking distance is greater than the determined spacing distance; and
in response to the determination that the calculated braking distance is greater than the obtained spacing distance, said output device providing to the driver one or more warning signals to avoid a collision between the moving vehicle and the second vehicle, wherein the one or more warning signals comprise a visual warning signal, an audio warning signal, or both the visual warning signal and the audio warning signal.

10. The computer program product of claim 9 , wherein said detecting one or more conditions comprises detecting current road conditions, weather conditions, or both road conditions and weather conditions.

11. The computer program product of claim 9 , wherein said calculating the braking distance comprises determining a minimal response distance for a specific monitored speed and deceleration of the moving vehicle and adding an additional response distan
