Abstract

A driver control input device includes first and second base members with first and second control members each configured to support an arm of a driver and each pivotally movable with respect to the base members in a generally horizontal plane. The control members are operatively engaged with a steer-by-wire system such that pivotal movement of the first and second control members causes steering control signals to be sent to the steer-by-wire system. The control members may also be longitudinally slidably supported with respect to the base members to generate acceleration and braking signals.

Claims

1. A driver control input device comprising:

at least one base member; and

at least one control member configured to support an arm of a driver and pivotally movable with respect to said at least one base member in a generally horizontal plane and operatively engaged with a steer-by-wire system such that pivotal movement of said at least one control member causes steering control signals to be sent to the steer-by-wire system.

2. The driver control input device of claim 1, wherein said at least on base member comprises first and second base members, and said at least one control member comprises first and second control members.

3. The driver control input device of claim 2, wherein said first and second control members are also slidably supported with respect to the first and second base members and operatively engaged with an energy conversion system, such that longitudinal sliding movement of the first and second control members causes acceleration signals to be sent to the energy conversion system.

4. The driver control input device of claim 2, wherein said first and second control members are also slidably supported with respect to the first and second base members and operatively engaged with a brake-by-wire system such that longitudinal sliding movement of the first and second control members causes braking signals to be sent to the brake-by-wire system.

5. The driver control input device of claim 2, wherein said first and second control members are also slidably supported with respect to the first and second base members and operatively engaged with an energy conversion system and a brake-by-wire system such that longitudinal sliding movement of the first and second control members in a first direction causes acceleration signals to be sent to the energy conversion system and longitudinal sliding movement of the first and second control members in an opposite direction causes braking signals to be sent to the brake-by-wire system.

6. The driver control input device of claim 5, further comprising a steering transducer operatively connected with said first and second control members to convert pivotal movement of the first and second control members into steering control signals, and an acceleration/braking transducer operatively connected with said first and second control members to convert longitudinal sliding movement of the first and second control members into acceleration and braking signals.

7. The driver control input device of claim 2, further comprising a steering transducer operatively connected with said first and second control members to convert pivotal movement of the first and second control members into steering control signals.

8. The driver control input device of claim 2, further comprising first and second hand grips on said first and second control members, respectively, and an acceleration demand input mechanism and a braking demand input mechanism positioned on at least one of said hand grips to facilitate sending acceleration and braking signals to an energy conversion system and a brake-by-wire system.

9. The driver control input device of claim 2, further comprising:

first and second hand grips on said first and second control members, respectively, and an acceleration demand input mechanism and a braking demand input mechanism positioned on at least one of said hand grips to facilitate sending acceleration and braking signals to an energy conversion system and a brake-by-wire system; and

wherein said first and second control members are also slidably supported with respect to the first and second base members and operatively engaged with the energy conversion system and the brake-by-wire system such that longitudinal sliding movement of the first and second control members in a first direction causes acceleration signals to be sent to the energy conversion system and longitudinal sliding movement of the first and second control members in an opposite direction causes braking signals to be sent to the brake-by-wire system, thereby providing redundant control of acceleration and braking.

10. The driver control input device of claim 2, wherein said first and second control members are sufficiently linked or synchronized such that if either control member is pivoted the other control member will rotate the same distance in the same rotational direction.

11. A driver control input device comprising:

first and second base members;

first and second control members each configured to support an arm of a driver and each pivotally movable with respect to the base members in a generally horizontal plane and operatively engaged with a steer-by-wire system such that pivotal movement of the first and second control members causes steering control signals to be sent to the steer-by-wire system;

said first and second control members also being longitudinally slidably supported with respect to the first and second base members and operatively engaged with an energy conversion system and a brake-by-wire system such that longitudinal sliding movement of the first and second control members in a first direction causes acceleration signals to be sent to the energy conversion system and longitudinal sliding movement of the first and second control members in an opposite direction causes braking signals to be sent to the brake-by-wire system.

12. The driver control input device of claim 11, further comprising a steering transducer operatively connected with said first and second control members to convert pivotal movement of the first and second control members into steering control signals, and an acceleration/braking transducer operatively connected with said first and second control members to convert longitudinal sliding movement of the first and second control members into acceleration and braking signals.

13. The driver control input device of claim 11, further comprising first and second hand grips on said first and second control members, respectively, and an acceleration demand input mechanism and a braking demand input mechanism positioned on at least one of said hand grips to facilitate sending acceleration and braking signals to said energy conversion system and brake-by-wire system.

14. The driver control input device of claim 11, wherein said first and second control members are sufficiently linked or synchronized such that if either control member is pivoted the other control member will rotate the same distance in the same rotational direction.

15. A vehicle comprising:

a chassis;

at least three wheels operatively connected with respect to the chassis;

a steering system mounted with respect to the chassis and responsive to non-mechanical control signals;

a braking system mounted with respect to the chassis and responsive to non-mechanical control signals;

an energy conversion system mounted with respect to the chassis and responsive to non-mechanical control signals;

first and second base members mounted with respect to the chassis;

first and second control members each configured to support an arm of a driver and each pivotally movable with respect to the base members in a generally horizontal plane and operatively engaged with a steer-by-wire system such that pivotal movement of the first and second control members causes steering control signals to be sent to the steering system; and

said first and second control members being also slidably supported with respect to the first and second base members and operatively engaged with said energy conversion system and braking system such that longitudinal sliding movement of the first and second control members in a first direction causes acceleration signals to be sent to the energy conversion system and longitudinal sliding movement of the first and second control members in an opposite direction causes braking signals to be sent to the braking system.

16. The vehicle of claim 15, further comprising a steering transducer operatively connected with said first and second control members to convert pivotal movement of the first and second control members into steering control signals, and an acceleration braking transducer operatively connected with said first and second control members to convert longitudinal sliding movement of the first and second control members into acceleration and braking signals.
