Abstract

Systems and device configurations are provided for reducing misstep, such as miscommunication between a vehicle and a driver that results in applying the incorrect pedal. Vehicle pedal configurations having a positioning element are described. Embodiments include pedal configurations having a pedal pad and at least one positioning element to adjust the pedal pad in response to pedal misstep. Pedal adjustment can include rotation of a pedal pad, rotation of portions of a pedal pad, and multibody pedal pad configurations. According to embodiment, a pedal pad includes vibrational elements to control vibration of the pedal. Embodiments are also directed to a pedal configuration including a flip plate. Systems are provided including a controller to control a pedal configuration and positioning elements. The controller may control the pedal based on a driving mode, such as an assistive driving state wherein operator is instructed to apply a pedal.

First claim

What is claimed is:

1. A vehicle pedal system including:
a pedal arm;
a pedal pad attached to the pedal arm, the pedal pad having a surface; and
a controller configured to control at least one actuator to rotate the pedal pad along a horizontal axis of the vehicle relative to the pedal arm between a first position and a second tilted position;
wherein in the first position the surface of the pedal pad faces a driver and is configured to be pressed by the driver to operate the pedal pad and pedal arm and in the second tilted position, the surface of the pedal pad faces away from the driver which prevents the driver from contacting the surface of the pedal pad and thus operating the pedal pad and pedal arm.

2. The vehicle pedal system according to claim 1 , wherein the pedal pad has a central axis and the pedal pad is configured to rotate about the central axis.

3. The vehicle pedal system according to claim 2 , wherein the pedal pad has a unibody configuration.

4. The vehicle pedal system according to claim 2 , wherein:
the pedal pad has a multibody configuration including two halves disposed on opposed sides of the central axis;
wherein each of the two halves is configured to rotate downwards about the central axis.

5. The vehicle pedal system according to claim 1 , further comprising:
a second pedal arm and a second pedal pad attached to the second pedal arm;
wherein rotation of the pedal pad from the first position to the second titled position along the horizontal axis is in a direction toward the second pedal arm and second pedal pad.

6. The vehicle pedal system according to claim 1 , wherein the pedal pad has a central axis and the pedal pad is configured to rotate about an axis that is offset from the central axis.

7. The vehicle pedal system according to claim 1 , wherein the pedal pad includes a support and a flip plate, wherein the flip plate includes the surface and is rotatable relative to the support.

8. The vehicle pedal system according to claim 1 , wherein the pedal pad is at least one of a vehicle accelerator pedal pad and a vehicle brake pedal pad.

9. The vehicle pedal system according to claim 1 , wherein the controller is configured to implement assistive driving operations.

10. The vehicle pedal system according to claim 9 , wherein the assistive driving operations include monitoring vehicle conditions and determining based on the monitored vehicle conditions that contact with the surface of the pedal pad is prohibited and in response the controller is configured to control the at least one actuator to rotate the surface of the pedal pad into the second tilted position.

11. The vehicle pedal system according to claim 10 , further comprising: a sensor configured to determine a driver foot position relative to the pedal pad.

12. The vehicle pedal system according to claim 11 , wherein the assistive driving operations includes the controller:
determining, through the sensor, that the driver's foot contacts the surface of the pedal pad,
monitoring vehicle conditions,
determining based on the monitored vehicle conditions that contact with the surface of the pedal pad is prohibited and in response the controller is configured to control the at least one actuator to rotate the surface of the pedal pad into the second tilted position to remove the driver's foot from the surface of the pedal pad.
