Abstract

Embodiments of an apparatus and methods of use thereof are provided. An apparatus for work zone intrusion detection related to a stationary vehicle, whereby the apparatus includes a processor configured to receive radar detection data about an oncoming vehicle and determine when to trigger an alarm sound in accordance with the radar detection data upon determining that the oncoming vehicle is moving in a direction and at an orientation to collide with the stationary vehicle. A method of using an apparatus for detecting and warning against intrusion in a work zone around a stationary vehicle is provided that includes obtaining, from a radar unit, detection data for a moving vehicle or object approaching the stationary vehicle, and determining, using a processor, when to trigger an alarm sound to allow a response time according to the detection data and a warning mode.

Claims

1. An apparatus for a vehicle, the apparatus comprising:

a housing of the apparatus, wherein the apparatus is configured to detect an oncoming vehicle with respect to a stationary vehicle, the housing further comprising;

a processor configured to receive radar detection data about an oncoming vehicle or object and determine when to trigger an alarm sound in accordance with the radar detection data and in accordance with a determination that the oncoming vehicle or object is moving in a direction to collide with the stationary vehicle,

wherein the radar detection data indicates at least one of speed and distance of the oncoming vehicle or object with respect to the stationary vehicle,

and further wherein the radar detection data indicates a position and orientation of the oncoming vehicle or object with respect to the stationary vehicle;

one or more switches, wherein the one or more switches are adapted for selecting one or more warning modes comprising a highway mode and a city mode, wherein the highway mode provides a greater response time than a response time provided for the city mode, wherein the alarm sound is triggered earlier for the highway mode than for the city mode, and further comprising a warning mode to provide a greater response time depending on a road condition or a weather condition; and

a transceiver coupled to the processor and configured to receive the radar detection data from a radar unit.

2. The apparatus of claim 1, wherein the apparatus further comprises or is coupled to an alarm sound device comprising a speaker for sounding the alarm sound.

3. The apparatus of claim 1, wherein the apparatus further comprises or is coupled to the radar unit, wherein the radar unit is configured to send the radar detection data to the transceiver.

4. The apparatus of claim 3, wherein the processor is located in a separate control unit and not located in a same device as the radar unit.

5. The apparatus of claim 3, wherein the radar unit is mountable on a surface of the stationary vehicle.

6. The apparatus of claim 3, wherein the radar unit and the processor are collocated in a single device box.

7. The apparatus of claim 1, wherein the apparatus further comprises or is coupled to a user interface for selecting or adjusting one or more warning modes, and wherein the processor is further configured to determine when to trigger the alarm sound in accordance with a selected warning mode.

8. The apparatus of claim 1, wherein the apparatus further comprises or is coupled to a global positioning system (GPS) configured to detect a location of the stationary vehicle for selecting one or more warning modes, and wherein the processor is further configured to determine when to trigger the alarm sound in accordance with a selected warning mode.

9. A method of warning an operator of a stationary vehicle, comprising:

obtaining, from a radar unit, radar detection data for a moving vehicle or object approaching the stationary vehicle; and

determining, using a processor and a transceiver coupled to the processor and configured to receive the detection data from the radar unit, when to trigger an alarm sound to allow a response time according to the detection data and a selected one or more warning modes;

determining a position and orientation of the moving vehicle or object with respect to the stationary vehicle; and

upon determining that the moving vehicle or object is moving in a direction to collide with the stationary vehicle based on the position and orientation of the moving vehicle or object, triggering the alarm sound to alert the operator of the stationary vehicle of an oncoming moving vehicle or object further comprising;

triggering a timing of the alarm sound based on the one or more selected warning modes, which are selected using one or more mode switches, wherein the one or more selected warning modes comprises a highway mode and a city mode, wherein the alarm sound is triggered earlier for the highway mode than the city mode, and further comprising triggering the timing of the alarm sound based on a warning mode to provide a greater response time depending on a road condition or a weather condition.

10. The method of claim 9, wherein the one or more warning modes are selected according to user input or global positioning system (GPS) data.

11. The method of claim 9, wherein the detection data includes at least one of speed and distance of the moving vehicle or object, and wherein triggering the alarm sound is determined according to at least one of the speed and the distance of the oncoming moving vehicle or object.

12. The method of claim 9, wherein the alarm sound is triggered when the moving vehicle reaches a threshold distance from the stationary vehicle, and wherein the threshold distance is selected in accordance with the warning mode.

13. The method of claim 9, wherein the one or more warning modes are selected in accordance with traffic limit speed or average speed on a highway or roadway.

14. The method of claim 9, further comprising setting a detection range for the radar unit according to the one or more warning modes.

15. An apparatus for warning an operator of a stationary vehicle, the apparatus comprising:

a controller unit configured for work zone intrusion detection related to the stationary vehicle, wherein the controller unit is connectable to a radar unit mountable on the stationary vehicle, wherein the controller unit is configured to receive detection data from the radar unit indicating an oncoming vehicle or object, including detection data related to a position and orientation of the oncoming vehicle or object with respect to the oncoming vehicle or object, and to trigger an alarm sound in accordance with the detection data to allow a response time according to one or more warning modes and according to a determination that the oncoming vehicle or object is moving in a direction to collide with the stationary vehicle;

one or more mode switches adapted for selecting the one or more warning modes, the one or more warning modes comprising a highway mode and a city mode, wherein the highway mode provides a greater response time than a response time provided for the city mode, wherein the alarm sound is triggered earlier for the highway mode than if the city mode is selected, and further comprising a warning mode to provide a greater response time depending on a road condition or a weather condition; and

a transceiver coupled to the processor and configured to receive the radar detection data from a radar unit.

16. The apparatus of claim 15, wherein the apparatus further comprises or is coupled to a sound device comprising a speaker for sounding the alarm sound.

17. The apparatus of claim 15, wherein the radar unit and the controller unit are collocated in a single device.

18. The apparatus of claim 15, wherein the controller unit and the radar unit are mountable on a surface on or in the stationary vehicle.
