Systems and methods are provided for influential control over a driver's operation of a vehicle's steering wheel. Upon issuing an autonomous control signal to control motive operation of the vehicle, an autonomous control system of the vehicle may reinforce or influence the application of the autonomous control signal by inducing or cuing to induce the driver's hand(s) to turn the vehicle's steering wheel in a particular direction or by a particular amount/with a particular level of torque.

No: 17/477158 Application Filed: September 16, 2021 Assignees: Toyota Research Institute, Inc. (Los Altos, CA, US) Claim: 1. A vehicle, comprising: an autonomous control system adapted to provide one or more commands to autonomously control one or more systems of the vehicle; and an influential control component adapted to impart influential control over a driver's operation of a steering wheel of the vehicle, the imparted influential control effectuating cues for the driver to adjust the driver's actuation of the steering wheel by rotating one or more directional cue wheels on a surface of the steering wheel; wherein the directional cue wheels rotate about an axis perpendicular to an axis of rotation of the steering wheel. Claim: 2. The vehicle of claim 1 , wherein the one or more directional cue wheels are positioned on a rim surface of the steering wheel. Claim: 3. The vehicle of claim 1 , wherein a direction of rotation of the one or more directional cue wheels comprises one of a counterclockwise direction and a clockwise direction, the counterclockwise and clockwise directions corresponding to cues to turn the vehicle to the left and right, respectively. Claim: 4. The vehicle of claim 1 , wherein a speed of rotation of the one or more directional cue wheels corresponds to a target amount of steering torque to be applied to the steering wheel. Claim: 5. The vehicle of claim 1 , further comprising an actuator operatively connected to the one or more directional cue wheels via a rotating shaft, the rotating shaft imparting rotational movement to the one or more directional cue wheels. Claim: 6. The vehicle of claim 5 , wherein the influential control component receives instructions from the autonomous control system to impart the influential control. Claim: 7. The vehicle of claim 6 , wherein the influential control component transmits actuation control signals to the actuator instructing the actuator to impart the rotational movement in accordance with a determined speed of rotation. Claim: 8. The vehicle of claim 6 , wherein the influential control component transmits actuation control signals to the actuator instructing the actuator to impart the rotational movement in accordance with a determined direction of rotation. Claim: 9. The vehicle of claim 5 , wherein computer code, when executed, further causes a processor of the autonomous control system to transmit instructions from the autonomous control system of the vehicle to the actuator to impart the rotational movement. Claim: 10. The vehicle of claim 9 , wherein the computer code comprises actuation control signals instructing the actuator to impart the rotational movement in accordance with a determined speed of rotation. Claim: 11. The vehicle of claim 9 , wherein the computer code comprises actuation control signals instructing the actuator to impart the rotational movement in accordance with a determined direction of rotation. Claim: 12. The vehicle of claim 1 , wherein the directional cue wheels are fixed in a position relative to the steering wheels and rotate about the axis at the position. Claim: 13. A vehicle, comprising: a processor; and a memory unit operatively connected to the processor and including computer code that when executed, causes the processor to: determine that the vehicle is approaching an environment requiring a first vehicle action; determine that the driver is applying a second vehicle action; and rotate one or more directional cue wheels on a surface of a steering wheel of the vehicle to indicate stopping the second vehicle action and conform to the first vehicle action; wherein the directional cue wheels rotate about an axis perpendicular to an axis of rotation of the steering wheel. Claim: 14. The vehicle of claim 13 , wherein altering the vehicle's operating characteristics comprises signaling one or more direction-cue wheels (DCWs) to conform to the first vehicle action. Claim: 15. The vehicle of claim 13 , further comprising determining a difference between the first vehicle action and the second vehicle action. Claim: 16. The vehicle of claim 13 , wherein the second vehicle action fails to complete the first vehicle action, and wherein altering the vehicle's operating characteristics comprises applying a correction to complete the first vehicle action.
