Abstract

An adjustable pedal system for a motor vehicle is presented. The system includes an adjustable pedal assembly being movable to at least two pedal positions and an adjustable pedal module, responsive to a pedal command, to control the movement of the adjustable pedal assembly. The pedal module includes a lockout module to disable the movement of the adjustable pedal assembly when a predetermined lockout condition is detected. The pedal module is interconnected through a data bus to at least one of vehicle electronic modules. The predetermined lockout condition is communicated to the adjustable pedal module over the data bus.

Claims

1. An adjustable pedal system for a motor vehicle, comprising:

an adjustable pedal assembly being movable to at least two pedal positions;

an adjustable pedal module, responsive to a pedal command, to control the movement of the adjustable pedal assembly, the pedal module including a lockout module to disable the movement of the adjustable pedal assembly when a predetermined lockout condition is detected; and

a data bus interconnecting at least one vehicle ECU and the adjustable pedal module, said adjustable pedal module verifying the integrity of said data bus, movement of the adjustable pedal assembly being allowed only after the data bus is verified;

wherein the predetermined lockout condition is communicated to the adjustable pedal module over the data bus.

2. The adjustable pedal system of claim 1 wherein the data bus is a J1850 data bus.

3. The adjustable pedal system of claim 1 wherein the pedal command is a stored input.

4. The adjustable pedal system of claim 3 wherein the pedal module is interconnected through a data bus to at least one vehicle electronics module;

and

wherein the pedal command is a pedal movement message communicated from a vehicle ECU.

5. The adjustable pedal system of claim 4 wherein the predetermined lockout condition is selected from the group comprising:

the vehicle is in reverse gear, the vehicle cruise control is engaged, the vehicle is in neutral gear, the vehicle is in drive, and the vehicle is in low gear.

6. The adjustable pedal system of claim 5 wherein the data bus is a J1850 data bus.

7. The adjustable pedal system of claim 5 wherein a vehicle operating condition is monitored to detect the predetermined lockout condition.

8. An adjustable pedal system for a motor vehicle, comprising:

an adjustable pedal assembly being movable to a desired position;

an adjustable pedal module, responsive to a pedal command from a manual input, to control the movement of the adjustable pedal assembly, the pedal module including a lockout module to disable the movement of the adjustable pedal assembly when a predetermined lockout condition is detected, the adjustable pedal module being interconnected through a data bus to at least one vehicle ECU, the adjustable pedal module verifying the integrity of the data bus and preventing movement of the adjustable pedal assembly when the integrity of the data bus is unverified; and

wherein the predetermined lockout condition is communicated to the adjustable pedal module over the data bus.

9. The adjustable pedal system of claim 8, wherein the data bus is a J1850 data bus.

10. The adjustable pedal system of claim 8, wherein the predetermined lockout condition is selected from the group comprising:

the vehicle is in reverse gear, and the vehicle cruise control is engaged.

11. The adjustable pedal system of claim 8, wherein a vehicle operating condition is monitored to detect the predetermined lockout condition.

12. An adjustable pedal system for a motor vehicle, comprising:

an adjustable pedal assembly being movable to at least two pedal positions;

an adjustable pedal module, responsive to a pedal command from a stored input, to control the movement of the adjustable pedal assembly, the pedal module including a lockout module to disable the movement of the adjustable pedal assembly when an unverified data bus is detected; and

the data bus interconnecting the adjustable pedal module to at least one vehicle electronics module, the adjustable pedal module verifying the integrity of the data bus;

wherein the pedal command is a pedal movement message communicated from the at least one vehicle electronic module over the data bus.

13. The adjustable pedal system of claim 12, wherein the lockout module further disables movement of the adjustable pedal assembly based on a predetermined lockout condition selected from the group consisting of:

the vehicle is in reverse gear, the vehicle cruise control is engaged, the vehicle is in neutral gear, the vehicle is in drive, and the vehicle is in low gear.

14. The adjustable pedal system of claim 13, wherein a vehicle operating condition is monitored to detect the predetermined lockout condition.

15. The adjustable pedal system of claim 12, wherein the data bus is a J1850 data bus.
