Vehicle control systems and methods and related vehicles
Systems for controlling the speed and direction of vehicles, including vehicles that have low to zero turning radius capability.
1. A vehicle control system comprising:
a first flexible member coupled to a first steering input member that is coupled to a first steerable wheel and to a steering input device such that an operator's manipulation of the steering input device for an outside turn of the first steerable wheel will cause movement of the first steering input member that will, in turn, cause the first flexible member to be pulled;
a control member operatively engaged with the first flexible member so that the control member will rotate as a result of the first flexible member being pulled; and
a first integration link coupled to the control member and configured to be coupled to a first drive unit, the first integration link including a first slot, the first slot including a first length, a first width, and a first depth, the first length being greater than the first width, and the first width being greater than the first depth.
2. The vehicle control system of claim 1 , further comprising:
a second integration link coupled to the control member and configured to be coupled to a second drive unit.
3. The vehicle control system of claim 1 , wherein the first flexible member comprises a cable.
4. The vehicle control system of claim 1 , further comprising:
a second steering input member;
a second flexible member coupled to the second steering input member that is coupled to a second steerable wheel and to the steering input member such that an operator's manipulation of the steering input device for an outside turn of the second steerable wheel will cause movement of the second steering input member that will, in turn, cause the second flexible member to be pulled, the second flexible member operatively engaged with the control member so that the control member will rotate as a result of the second flexible member being pulled; and
a second integration link coupled to the control member and configured to be coupled to a second drive unit.
5. The vehicle control system of claim 4 , wherein the first integration link is coupled to a first drive unit and the second integration link is coupled to a second drive unit.
6. The vehicle control system of claim 4 , wherein the second integration link includes a second slot, the second slot including a second length, a second width, and a second depth, the second length being greater than the second width, and the second width being greater than the second depth.
7. The vehicle control system of claim 6 , wherein the first slot in the first integration link is straight along the first length and the second slot in the second integration link is straight along the second length.
8. The vehicle control system of claim 7 , further comprising first and second integration members operatively engaged with the control member.
9. The vehicle control system of claim 8 , further comprising:
a first coupling member coupling the first integration member to the first integration link; and
a second coupling member coupling the second integration member to the second integration link;
wherein at least a portion of the first coupling member is positioned in the first slot of the first integration link and at least a portion of the second coupling member is positioned in the second slot of the second integration link.
10. The vehicle control system of claim 4 , wherein the second flexible member comprises a cable.
