Electronic shifter limp-home techniques
First Claim
1. A vehicle, comprising:
- an electronic shifter configured to electronically control shifting of a transmission in response to a gear control input provided by operation of the electronic shifter;
a steering wheel (i) configured to control steering of the vehicle and (ii) having one or more actuators associated with one or more vehicle systems other than the transmission in a non-malfunction state of the electronic shifter;
a display configured to display information; and
a controller configured to;
detect a malfunction of the electronic shifter,in response to detecting the malfunction of the electronic shifter;
(i) control the display to output driver assist information that is adapted to instruct a driver of the vehicle in providing the gear control input via the one or more actuators of the steering wheel, the driver assist information including (a) a current gear of the transmission and (b) how the one or more actuators of the steering wheel are configured to control various gears of the transmission; and
(ii) after the display outputs the driver assist information, receive the gear control input from the one or more actuators of the steering wheel, andcontrol shifting of the transmission in response to the gear control input received from the one or more actuators of the steering wheel.

Abstract
Limp-home techniques for situations when an electronic shifter of a vehicle malfunctions include detecting, at a controller of the vehicle, a malfunction of the electronic shifter of the vehicle, the electronic shifter being configured to control shifting of a transmission of the vehicle in response to a gear control input provided by operation of the electronic shifter. The techniques include, in response to detecting the malfunction of the electronic shifter, receiving, at the controller, the gear control input from actuation of the one or more actuators of a steering wheel of the vehicle. The techniques also include controlling, by the controller, shifting of the transmission in response to the gear control input received from the one or more actuators of the steering wheel.

7. A method, comprising:
-
detecting, at a controller of a vehicle, a malfunction of an electronic shifter of the vehicle, the electronic shifter being configured to control shifting of a transmission of the vehicle in response to a gear control input provided by operation of the electronic shifter; in response to detecting the malfunction of the electronic shifter; (i) controlling, by the controller, an interior display of the vehicle to output driver assist information that is adapted to instruct a driver of the vehicle in providing the gear control input via one or more actuators of a steering wheel of the vehicle, the driver assist information including (a) a current gear of the transmission and (b) how the one or more actuators of the steering wheel are configured to control various gears of the transmission, and the one or more actuators being associated with one or more vehicle systems other than the transmission in a non-malfunction state of the electronic shifter; and (ii) after the interior display outputs the driver assist information, receiving, at the controller, the gear control input from the one or more actuators of the steering wheel; and controlling, by the controller, shifting of the transmission in response to the gear control input received from the one or more actuators of the steering wheel. - View Dependent Claims (8, 9, 10, 11, 12)
