ABSTRACT:
A drive mechanism under the floor of a minivan is coupled to the folding ramp by a rotating arm linkage, also located beneath the floor. The extension of the folding ramp is partially controlled by dynamic braking, i.e. using the electric motor as a generator and coupling the motor to an electrical load.
