A microprocessor controlled system for ensuring the safe operation of an auxiliary device, such as a wheelchair lift used in conjunction with a vehicle. The microprocessor preferably allows operation of the lift device when one or more parameters are met. These parameters include the following: the vehicle is in 'park', the parking brake is engaged, the vehicle ignition is 'on', the lift power switch is &#x201c;on&#x201d;, and the lift door is open. The present invention does not allow the vehicle to be shifted out of park if the lift door is open and/or when the parking brake is &#x201c;on&#x201d;.

A microprocessor controlled system for ensuring the safe operation of an auxiliary device, such as a wheelchair lift used in conjunction with a vehicle. The microprocessor preferably allows operation of the lift device when one or more parameters are met. These parameters include the following: the vehicle is in park, the parking brake is engaged, the vehicle ignition is on, the lift power switch is on, and the lift door is open. The present invention further does not allow the vehicle to be shifted out of park if the lift door is open and/or when the parking brake is on.

For motor vehicles equipped with overdrive-equipped transmissions normally biased in one of the overdrive or non-overdrive modes of operation, a method for automatically biasing the transmission to the alternate mode of operation, and apparatus to practice the method. Normally used to bias transmissions from the overdrive to the non-overdrive mode of operation, the apparatus and method taught herein are particularly well-suited for operation in conjunction with automatic transmissions, and are actuated uniquely with each ignition run cycle. Alternatively, the method and apparatus may, with equal facility, incorporate other vehicle operations and conditions to actuate its overdrive biasing function.
