In-vehicle haptic output

1. A method, comprising:

detecting, by a computer, at least one of a sound outside of a vehicle and an event indicated by a communications bus in the vehicle;

determining, by the computer, that at least one of the sound and the event is mapped to a haptic output;

instructing, by the computer, a portable computing device to actuate the haptic output; and

preventing, by the computer, the portable computing device from actuating the haptic output based on a speed of the vehicle.

2. The method of claim 1 , further comprising receiving, by the computer, operator input mapping the sound to the haptic output.

3. The method of claim 1 , further comprising actuating, by the computer, a second haptic output based on a second detected sound.

4. The method of claim 1 , further comprising, prior to detecting the sound and prior to actuating the haptic output, determining, by the computer, that a vehicle operator associated with the portable computing device is hearing-impaired.

5. The method of claim 4 , wherein determining that the vehicle operator is hearing impaired is performed by recognizing that an application running on the portable device is provided for a hearing impaired user.

6. The method of claim 1 , wherein the event is one of a speed of the vehicle and an impending collision of the vehicle.

7. The method of claim 1 , wherein the event is a dedicated short range communication from a second vehicle.

8. The method of claim 1 , wherein the haptic output includes a plurality of haptic outputs of a specified duration and at a specified intensity.

9. The method of claim 1 , further comprising detecting, by the computer, the event indicated by the communications bus in the vehicle, and determining, by the computer, that the event is mapped to the haptic output.

10. The method of claim 1 , wherein the event is a notification for an occupant of the vehicle.

11. A system, comprising a computer that includes a processor and a memory, the memory storing instructions executable by the processor such that the computer is programmed to:

detect at least one of a sound outside of a vehicle and an event indicated by a communications bus in the vehicle;

determine that at least one of the sound and the event is mapped to a haptic output;

instruct a portable computing device to actuate the haptic output; and

prevent the portable computing device from actuating the haptic output based on a speed of the vehicle.

12. The system of claim 11 , wherein the computer is further programmed to receive operator input mapping the sound to the haptic output.

13. The system of claim 11 , wherein the computer is further programmed to actuate a second haptic output based on a second detected sound.

14. The system of claim 11 , wherein the computer is further programmed to, prior to detecting the sound and prior to actuating the haptic output, determine that a vehicle operator associated with the portable computing device is hearing-impaired.

15. The system of claim 14 , wherein determining that the vehicle operator is hearing impaired is performed by recognizing that an application running on the portable device is provided for a hearing impaired user.

16. The system of claim 11 , wherein the event is one of a speed of the vehicle and an impending collision of the vehicle.

17. The system of claim 11 , wherein the event is a dedicated short range communication from a second vehicle.

18. The system of claim 11 , wherein the haptic output includes a plurality of haptic outputs of a specified duration and at a specified intensity.

19. The system of claim 11 , wherein the computer is further programmed to detect the event indicated by the communications bus in the vehicle, and determine that the event is mapped to the haptic output.

20. The system of claim 11 , wherein the event is a notification for an occupant of the vehicle.
