Abstract

A computing device for a vehicle proximity condition detection and haptic notification system is provided. The device includes one or more processors for controlling operation of the computing device, and a memory for storing data and program instructions usable by the one or more processors. The one or more processors are configured to execute instructions stored in the memory to enable a user to specify operation of an active suspension system of an ego-vehicle so as to generate at least one pulse at at least one wheel of the vehicle, responsive to a vehicle proximity condition, and operate the active suspension system in accordance with the user'"'"'s specification.

Claims

1. A computing device for a vehicle, the computing device comprising:

one or more processors for controlling operation of the computing device, and

a memory for storing data and program instructions usable by the one or more processors, wherein the one or more processors are configured to execute instructions stored in the memory to;

enable a user to specify operation of an active suspension system of an ego-vehicle so as to generate at least one pulse in at least one wheel of the ego-vehicle responsive to a vehicle proximity condition comprising multiple occurrences of other vehicles approaching the ego-vehicle from a rear of the ego-vehicle at a higher speed than that at which the ego-vehicle is traveling, and then changing lanes; and

operate the active suspension system in accordance with the user-specified operation.

2. The computing device of claim 1 wherein the one or more processors are configured to execute instructions stored in the memory to enable a user to specify operation of an active suspension system of the ego-vehicle so as to respond to the low speed condition by generating a pulse or series of pulses only in one or more rear wheels of the ego-vehicle.

3. A computing device for a vehicle, the computing device comprising:

one or more processors for controlling operation of the computing device, and

a memory for storing data and program instructions usable by the one or more processors, wherein the one or more processors are configured to execute instructions stored in the memory to;

enable a user to specify operation of an active suspension system of an ego-vehicle so as to generate at least one pulse in at least one wheel of the ego-vehicle and to, simultaneously with generating at least one pulse in at least one wheel of the ego-vehicle, tilt only a seat of the ego-vehicle toward a rear of the ego-vehicle responsive to a vehicle proximity condition and so as to provide a user-selected haptic response directed to informing an ego-vehicle occupant of the vehicle proximity condition; and

operate the active suspension system in accordance with the user-specified operation.

4. The computing device of claim 3 wherein the vehicle proximity condition comprises a low following distance condition in which a following distance of the ego-vehicle behind a preceding vehicle traveling in a lane in which both the ego-vehicle and the preceding vehicle are traveling, is determined to be too small.

5. A computing device for a vehicle, the computing device comprising:

one or more processors for controlling operation of the computing device, and a memory for storing data and program instructions usable by the one or more processors, wherein the one or more processors are configured to execute instructions stored in the memory to;

enable a user to define a virtual space envelope around the ego-vehicle;

enable a user to specify operation of an active suspension system of an ego-vehicle so as to generate at least one pulse in at least one wheel of the ego-vehicle responsive to an incursion of another vehicle into a user-defined virtual space envelope defined around the ego-vehicle; and

operate the active suspension system in accordance with the user-specified operation.

6. The computing device of claim 5 wherein the vehicle proximity condition comprises an incursion of another vehicle into the virtual space envelope proximate a front of the ego-vehicle, and wherein the one or more processors are configured to execute instructions stored in the memory to enable a user to specify operation of the active suspension system so as to generate the at least one pulse at each front wheel of the ego-vehicle, responsive to the vehicle proximity condition.

7. The computing device of claim 5 wherein the vehicle proximity condition comprises an incursion of another vehicle into the virtual space envelope proximate a rear of the ego-vehicle, and wherein the one or more processors are configured to execute instructions stored in the memory to enable a user to specify operation of the active suspension system so as to generate the at least one pulse at each rear wheel of the ego-vehicle, responsive to the vehicle proximity condition.

8. The computing device of claim 5 wherein the vehicle proximity condition comprises an incursion of another vehicle into the virtual space envelope along a side of the ego-vehicle, and wherein the one or more processors are configured to execute instructions stored in the memory to enable a user to specify operation of the active suspension system so as to generate the at least one pulse at each wheel along a side of the ego-vehicle on which the other vehicle resides, responsive to the vehicle proximity condition.

9. The computing device of claim 5 wherein the one or more processors are configured to execute instructions stored in the memory to enable a user to specify operation of an active suspension system of the ego-vehicle so as to respond to an incursion of the virtual space envelope proximate a rear of the ego-vehicle by another vehicle traveling in a lane adjacent a lane in which the ego-vehicle is traveling, by generating the least one pulse at a rear wheel of the ego-vehicle closest to the adjacent lane.

10. The computing device of claim 5 wherein the one or more processors are configured to execute instructions stored in the memory to enable a user to specify operation of an active suspension system of the ego-vehicle so as to respond to an incursion of the virtual space envelope proximate a front of the ego-vehicle by another vehicle traveling in a lane adjacent a lane in which the ego-vehicle is traveling, by generating the least one pulse at a front wheel of the ego-vehicle closest to the adjacent lane.

11. The computing device of claim 5 wherein the one or more processors are configured to execute instructions stored in the memory to enable variation of a magnitude of the at least one pulse responsive to incursion of another vehicle into the virtual space envelope defined around the ego-vehicle, according to a speed of the other vehicle.

12. The computing device of claim 5 wherein the one or more processors are configured to execute instructions stored in the memory to enable variation of a magnitude of the at least one pulse responsive to incursion of another vehicle into the virtual space envelope defined around the ego-vehicle, according to a proximity of the other vehicle to the ego-vehicle.

13. A method, in a computing system, of operating at least a portion of an ego-vehicle responsive to an occurrence of a vehicle proximity condition, comprising steps of:

receiving user input specifying operation of an active suspension system of the ego vehicle so as to generate at least one pulse in at least one wheel of the ego-vehicle responsive to an incursion of another vehicle into a user-defined virtual space envelope around the ego-vehicle, the space envelope having a boundary residing at a distance R from a front of the ego-vehicle and at a distance r from each side of the ego-vehicle, where R>

r and operating the active suspension system in accordance with the user-specified operation.

14. A computing device for a vehicle, the computing device comprising:

one or more processors for controlling operation of the computing device, and a memory for storing data and program instructions usable by the one or more processors, wherein the one or more processors are configured to execute instructions stored in the memory to;

enable a user to define a virtual space envelope around the ego-vehicle;

enable a user to specify an operation of an active suspension system of the ego-vehicle to be implemented responsive to an incursion of another vehicle into a user-defined virtual space envelope so as to provide a user-selected haptic response directed to informing an ego-vehicle occupant of the incursion, and operate the active suspension system in accordance with the user-specified operation.

15. The computing device of claim 14 wherein the space envelope has a boundary residing at a distance R from a front of the ego-vehicle and at a distance r from each side of the ego-vehicle, and wherein R>
