Drive-by-wire system for vehicle, zero-turn-radius lawnmower including same, and drive-by-wire system for lawnmower

A drive-by-wire system for a lawnmower including a first motor and a second motor, the drive-by-wire system comprising:

• a first operator input configured to transmit a first signal;
• a second operator input configured to transmit a second signal;
• and
• a mode selector configured to output a mode signal, and
• a controller in electrical communication with the mode selector, the first operator input, and the second operator input, and configured to,
• determine one of a plurality of first conditions based on the first signal, the plurality of first conditions includes a first neutral condition and a plurality of first drive conditions,
• determine one of a plurality of second conditions based on the second signal, the plurality of second conditions includes a second neutral condition and a plurality of second drive conditions,
• determine whether the mode signal is indicative of a first mode request or a second mode request,
• operate in a first mode when the controller determines that the mode signal corresponds to the first mode request, and
• operate in a second mode when the controller determines that the mode signal corresponds to the second mode request,
• in the first mode,
• drive the first motor at a first speed and in a first direction that correspond directly to the first signal when the controller determines one of the first drive conditions,
• drive the second motor at a second speed and in a second direction that correspond directly to the second signal when the controller determines one of the second drive conditions,
• cause the first motor to be idle when the controller determines the first neutral condition, and
• cause the second motor to be idle when the controller determines the second neutral condition;
• and
• in the second mode,
• drive the first motor and the second motor in a same direction and at a same speed when the controller determines the second neutral condition and one of the first drive conditions,
• drive the first motor at a first turning speed and in the same direction and the second motor at a second turning speed and in one of the same direction and an opposite direction when the controller determines one of the first drive conditions and one of the second drive conditions, and
• cause the first motor and the second motor to be idle when the controller determines the first neutral condition.

A drive-by-wire system for a lawnmower including a first motor selectively and a second motor, the drive-by-wire system comprising:

• a first handle and a second handle, each of the first and second handles is movable into a first range, a second range, and a neutral position that is separate from the first range and the second range;
• and
• a controller in electrical communication with the first handle and the second handle, the controller is configured to,
• in a first operation mode,
• drive the first motor when the first handle is in the first range or the second range,
• drive the second motor when the second handle is in the first range or the second range,
• cause the first motor to be idle when the first handle is in the neutral position, and
• cause the second motor to be idle when the second handle is in the neutral position
• in a second operation mode,
• drive the first motor and the second motor when the second handle is the neutral position and the first handle is in the first range or the second range.
