Abstract
This invention is an improved park position locking system for controlling the conditions for removing an automatic transmission gearshift from a PARK position. An electronic system controller and the transmission controller are engaged to a common data bus . Vehicle control system comprises the electronic system controller (ESC) , which is the primary component of a vehicle electronic control system. ESC manages and communicates with a number of vocational controllers disposed on a vehicle and executes a load management program which oversees the total load imposed on the vehicle electrical system and power train by various accessories installed on the vehicle . Such communication is by a standard communication protocol that may be the SAE J1939 protocol over the common data bus . The ESC is programmed to ensure that an operator of the vehicle may not move the gearshift out of a PARK position without first depressing a service brake pedal. The ESC prevents or allows movement of the gearshift through a solenoid operated locking mechanism engaged to the gearshift
