Vehicle component operation

1. A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the computer to:

operate a component in a vehicle in an autonomous mode;

detect an impact to the vehicle;

suppress actuation of the component in the autonomous mode; and

then actuate any of a propulsion, a brake, and a steering only according to user input.

2. The system of claim 1 , wherein the instructions further include instructions to receive authentication data and to activate autonomous operation of the propulsion, the brake, and the steering upon receipt of the authentication data.

3. The system of claim 1 , wherein the instructions further include instructions to, upon detecting the impact, actuate a parking brake and then actuate any of the propulsion, the brake, and the steering only according to user input.

4. The system of claim 1 , wherein the instructions further include instructions to receive manual user input and actuate at least one of the propulsion, the brake, and the steering based on the manual user input.

5. The system of claim 1 , wherein the instructions further include instructions to deactivate power to the component upon detecting the impact.

6. The system of claim 1 , wherein the instructions further include instructions to suppress electrical signals from a virtual operator to the component.

7. The system of claim 1 , wherein the instructions further include instructions to actuate the brake upon receiving input from a mechanical actuator.

8. A system, comprising:

a component in a vehicle;

an interface connected to the component including means for manually actuating the component;

means for autonomously operating the component;

means for detecting an impact to the vehicle;

means for suppressing autonomous operation of the component upon detecting the impact; and

upon detecting the impact, means for actuating any of a propulsion, a brake, and a steering only according to user input to the means for manually actuating the component.

9. The system of claim 8 , further comprising means for receiving authentication data and means for activating autonomous operation of the component upon receipt of the authentication data.

10. The system of claim 8 , further comprising means for actuating a parking brake upon detecting the impact.

11. The system of claim 8 , further comprising means for suppressing electrical signals from a virtual operator to the component.

12. The system of claim 8 , further comprising means for preventing autonomous actuation of a brake and means for manually actuating the brake.

13. A method, comprising:

operating a component in a vehicle in an autonomous mode;

detecting an impact to the vehicle;

suppressing actuation of the component in the autonomous mode; and

then actuating any of a propulsion, a brake, and a steering only according to user input.

14. The method of claim 13 , further comprising receiving authentication data and activating autonomous operation of the component upon receipt of the authentication data.

15. The method of claim 13 , further comprising detecting the impact, actuating a parking brake and then actuating any of a propulsion, a brake, and a steering only according to user input.

16. The method of claim 13 , further comprising suppressing electrical signals from a virtual operator to the component.

17. The method of claim 13 , further comprising actuating the brake upon receiving input from a mechanical actuator.
