A park-brake monitoring-system monitors the selected and actual operational states of a park-brake system of a vehicle. The park-brake monitoring-system includes one or more selected-state sensor(s) that produce signals implicative of the selected operational state of the park-brake system and one or more actual state sensor(s) that produce signal(s) implicative of the actual-operational state of the park-brake system. Logic device(s) of the park-brake monitoring-system operate dependent upon input from both the selected state sensor(s) and the actual state sensor(s).

Park-brake monitoring-system for a vehicle

A park-brake monitoring-system monitors the operating state of a park-brake system of a vehicle. The park-brake monitoring-system comprises operating-state sensors that produce and communicate sensed operating-state signals in manners dependent upon the operating state of the park-brake system to other components of the vehicle. The configuration and interaction with the park-brake system and the park-brake monitoring system of the operating-state sensors is refined such that the sensed operating-state signals produced thereby include signal types that are implicative of the park-brake system having a fully-set operating state, signal types that are implicative of the park-brake system having a fully-released operating state, signal types implicative of the park-brake system having a not-fully-released operating state, and signal types implicative of the park-brake system having a not-fully-set operating state.

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

Park position locking system for automatic transmission shifter

A driver control module for a vehicle and a method of assembling and installing the driver control module in the vehicle. The driver control module includes the operator control pedals, the steering column and a large portion of the brake actuation system of the vehicle. The driver control module is designed to be assembled as a unit and then mounted to the dash of the vehicle.
