Abstract

Techniques are provided for deactivating or disabling one or more actuators of a steering wheel of a vehicle to prevent unintended actuation. In one example, the techniques include detecting, at a controller of the vehicle, a deactivation condition, which includes an operating condition of the vehicle indicative of a lack of interaction by a driver with the one or more actuators of the steering wheel. The one or more actuators are configured to receive an input from the driver to control or actuate one or more associated vehicle systems. In response to detecting the deactivation condition, the techniques include deactivating or disabling, by the controller, the one or more actuators of the steering wheel until the deactivation condition is no longer present.

Claims

1. A vehicle, comprising:

a steering wheel having one or more actuators configured to receive an input from a driver to control or actuate one or more associated vehicle systems; and

a controller configured to;

detect a deactivation condition including;

(i) a speed of the vehicle being less than a predetermined vehicle speed for a predetermined period of time indicative of the vehicle being in the process of parking, and

(ii) a transmission of the vehicle being in a reverse gear;

in response to detecting the deactivation condition, deactivating or disabling the one or more actuators of the steering wheel until the deactivation condition is no longer present, wherein the controller is configured to ignore the input received from the one or more actuators while they are deactivated or disabled.

2. The vehicle of claim 1, wherein in response to detecting the deactivation condition is no longer present, the controller is further configured to reactivate the one or more actuators of the steering wheel.

5. The vehicle of claim 1, wherein the deactivation condition further includes at least one of a yaw angle of a set of wheels of the vehicle and a rate of change of the yaw angle being greater than a respective yaw threshold.

7. The vehicle of claim 1, wherein the deactivation condition further includes a parallel parking mode of the vehicle being enabled.

3. A method, comprising:

detecting, at a controller of a vehicle, a deactivation condition including;

(i) a speed of the vehicle being less than a predetermined vehicle speed for a predetermined period of time indicative of the vehicle being in the process of parking, and

(ii) a transmission of the vehicle being in a reverse gear; and

in response to detecting the deactivation condition, deactivating or disabling, by the controller, one or more actuators of a steering wheel of the vehicle until the deactivation condition is no longer present, wherein the one or more actuators are configured to (i) receive an input from a driver of the vehicle to control or actuate one or more associated vehicle systems, and wherein the controller is configured to ignore the input received from the one or more actuators while they are deactivated or disabled.

4. The method of claim 3, further comprising reactivating, by the controller, the one or more actuators of the steering wheel in response to detecting, at the controller, that the deactivation condition is no longer present.

6. The method of claim 3, wherein the deactivation condition further includes at least one of a yaw angle of a set of wheels of the vehicle and a rate of change of the yaw angle being greater than a respective yaw threshold.

8. The method of claim 3, wherein the deactivation condition further includes information from an image sensor or a camera of the vehicle that is indicative of the vehicle being in the process of parking.
