Claim 25:
26. A method for preventing jack-knifing of a tractor-trailer vehicle configuration using a converter dolly towing a second trailer behind a first trailer, the first trailer being towed by a towing vehicle, the converter dolly comprising at least one axle having at least a first wheel on a left side of the converter dolly and a second wheel on the right side of the converter dolly, the first wheel being operably coupled to a first motor, the second wheel being operably coupled to a second motor, such that the first motor and second motor are each operable in a drive mode for applying a motive rotational force to the first or second wheel respectively,
and a controller operably coupled to the first motor and the second motor for selectively activating and deactivating the drive mode,
the method comprising:
while the drive mode of the first motor and the drive mode of the second motor are activated:
detecting a jack-knifing risk condition of the tractor-trailer vehicle configuration by a forward jack-knifing detection system; and
deactivating the drive mode of the first motor and second motor based at least in part on the detection of the jack-knifing risk condition.
