Vehicle gear selection control
A motor vehicle for operation by a driver has a frame with wheels and a motor connected to the frame. A steering control is connected to the wheels to establish a steering angle. A controller is operably connected to the steering control, to the motor, and to the wheels, and is operable to selectably drive the wheels in a forward direction in a drive mode and in a rearward direction in a reverse mode. The controller is operable to select a direction for driving the wheels in response to a pattern of steering angle movements, without operator indication of a direction.
1. A motor vehicle comprising:
a frame having wheels;
a motor connected to the frame;
a steering control connected to the wheels to establish a steering angle;
a drive system operably connected to the steering control, to the motor, and to the wheels;
the drive system operable to selectably drive the wheels in a forward direction in a drive mode and in a rearward direction in a reverse mode; and
the drive system operable to select a direction for driving the wheels in response to steering angle movements, without operator indication of a direction.
2. The motor vehicle of claim 1 including a brake control operable by a driver to generate a brake input, and wherein the drive system is operably connected to the brake control to receive the brake input, and wherein an approval indication includes actuation of the brake control.
3. The motor vehicle of claim 2 wherein the drive system includes an accelerator pedal operable to slow the vehicle in response to release of the accelerator pedal, and wherein operation of the brake control for the approval indication includes the driver's foot shifting from the accelerator pedal to tap the brake control.
4. The motor vehicle of claim 1 wherein the drive system is operable to offer a driver a change in the drive direction only in response to detecting a steering input greater than a selected steering angle threshold.
5. The motor vehicle of claim 1 wherein the drive system is operable to offer a driver a change in the drive direction only if a vehicle velocity is below a selected velocity threshold.
6. The motor vehicle of claim 1 wherein the drive system is operable to change the drive direction only in response to a steering input indicating steering in a first direction, then indicating steering in the opposite direction.
7. The motor vehicle of claim 1 wherein the drive system is operable to offer a driver a change in the drive direction based at least in part on distance traveled.
8. The motor vehicle of claim 1 wherein the drive system is operable in response to an approval indication from a driver to change the drive direction without driver indication of a direction other than approval of an offered change in direction.
9. The motor vehicle of claim 1 wherein the drive system is operable in response to an approval indication from a driver to change the drive direction without operation of a selector by the driver.
10. The motor vehicle of claim 1 including a brake control operable by a driver to generate a brake input, and wherein the drive system is operably connected to the brake control to receive the brake input, and wherein the drive system is operable in response to driving a first direction with steering angle in a first steering direction, then changing steering to an opposite second steering direction, to change drive direction in response to operation of the brake control by the driver.
11. A motor vehicle comprising:
a frame having wheels;
a motor connected to the frame;
a steering control connected to the wheels to establish a steering angle;
a controller operably connected to the steering control, to the motor, and to the wheels;
the controller operable to selectably drive the wheels in a forward direction in a drive mode and in a rearward direction in a reverse mode; and
the controller operable to select a direction for driving the wheels in response to steering angle movements, without operator indication of a direction.
12. The motor vehicle of claim 11 including a brake control operable by driver to generate a brake input, and wherein the controller is operably connected to the brake control to receive the brake input, and wherein an approval indication includes actuation of the brake control.
13. The motor vehicle of claim 12 wherein the controller includes an accelerator pedal operable to slow the vehicle in response to release of the accelerator pedal, and wherein operation of the brake control for the approval indication includes the driver's foot shifting from the accelerator pedal to tap the brake control.
14. The motor vehicle of claim 11 wherein the controller is operable to offer a driver a change in the drive direction only in response to detecting a steering input greater than a selected steering angle threshold.
15. The motor vehicle of claim 11 wherein the controller is operable to offer a driver a change in the drive direction only if a vehicle velocity is below a selected velocity threshold.
16. The motor vehicle of claim 11 wherein the controller is operable to change the drive direction only in response to a steering input indicating steering in a first direction, then indicating steering in the opposite direction.
17. The motor vehicle of claim 11 wherein the controller is operable to offer a driver a change in the drive direction based at least in part on distance traveled.
18. The motor vehicle of claim 11 wherein the controller is operable in response to an approval indication from a driver to change the drive direction without driver indication of a direction other than approval of an offered change in direction.
19. The motor vehicle of claim 11 wherein the controller is operable in response to an approval indication from a driver to change the drive direction without operation of a selector by the driver.
20. The motor vehicle of claim 11 including a brake control operable by a driver to generate a brake input, and wherein the controller is operably connected to the brake control to receive the brake input, and wherein the controller is operable in response to driving a first direction with the steering angle in a first steering direction, then changing steering to an opposite second steering direction, to change drive direction in response to operation of the brake control by the driver.
