Abstract

A method for apprising a driver to a change in automation level of an automated self-drive system for a vehicle includes identifying an expected automation level change and communicating a required engagement level. The driver is thereby apprised of an appropriate level of engagement with each of a multiple of manual vehicle controls.

First claim

What is claimed:

1. A computer storage medium having embodied thereon non-transitory computer-readable instructions that, when executed, perform a method for apprising a driver to an expected automation level change in an automated self-drive system for a vehicle, the method comprising:
identifying, in a vehicle having a multiple of manual vehicle controls, but subject to control under an automated self-drive system according to a plurality of automation levels with mutually distinct sets of driver's responsibilities for operating the multiple of manual vehicle controls, an expected automation level change from a current automation level to an upcoming automation level; and
communicating, with a driver vehicle interface in the vehicle, a required engagement level for the expected automation level change to a driver, the communication including a specific instruction as to all of the driver's new responsibilities for operating the multiple of manual vehicle controls from the set of driver's responsibilities for operating the multiple of manual vehicle controls for the current automation level to that for the upcoming automation level upon the expected automation level change.

2. The method as recited in claim 1 , further comprising confirming whether the driver has complied with the required engagement level.

3. The method as recited in claim 2 , further comprising communicating the required engagement level to the driver at a heightened alert status in response to non-compliance with the required engagement level.

4. The method as recited in claim 3 , wherein the heightened alert status includes a haptic alert.

5. The method as recited in claim 4 , further comprising continuing the haptic alert until the driver has complied with the required engagement level.

6. The method as recited in claim 2 , further comprising communicating the required engagement level to the driver at a heightened alert status in response to non-compliance with the required engagement level until the driver complies.

7. The method as recited in claim 1 , wherein the multiple of manual vehicle controls includes a braking system, a steering system, and a throttle system.

8. The method as recited in claim 1 , wherein communicating the required engagement level to the driver includes audio communication.

9. The method as recited in claim 1 , wherein communicating the required engagement level to the driver includes visual communication.

10. The method as recited in claim 1 , wherein the multiple of manual vehicle controls includes a braking system, and a steering system.

11. A vehicle, comprising:
a multiple of manual vehicle controls;
an automated self-drive system under which the vehicle is controlled according to a plurality of automation levels with mutually distinct sets of driver's responsibilities for operating the multiple of manual vehicle controls;
a control system for identifying an expected automation level change from a current automation level to an upcoming automation level; and
a driver vehicle interface in communication with the control system for communicating a required engagement level for the expected automation level change to a driver, the communication including a specific instruction as to all of the driver's new responsibilities for operating the multiple of manual vehicle controls from the set of driver's responsibilities for operating the multiple of manual vehicle controls for the current automation level to that for the upcoming automation level upon the expected automation level change.

12. The vehicle as recited in claim 11 , further comprising a driver sensor that confirms if the required engagement level has been complied with.

13. The vehicle as recited in claim 12 , wherein the required engagement level is communicated to the driver at a heightened alert status in response to non-compliance with the required engagement level.

14. The vehicle as recited in claim 13 , wherein the heightened alert status includes a haptic alert.

15. The vehicle as recited in claim 14 , wherein the haptic alert is continued until the driver has complied with the required engagement level.

16. The vehicle as recited in claim 11 , wherein the driver vehicle interface visually communicates the required engagement level to the driver.

17. The vehicle as recited in claim 11 , wherein the multiple of manual vehicle controls includes a braking system, a steering system, and a throttle system.

18. The vehicle as recited in claim 11 , wherein the driver vehicle interface audibly communicates the required engagement level to the driver.

19. The vehicle as recited in claim 11 , wherein the required engagement level is communicated to the driver at a heightened alert status in response to non-compliance with the required engagement level until the driver complies.
