Abstract: An improved system and method of integrating GPS and wireless communication systems with the systems of a user's vehicle make the GPS and wireless communication systems more readily and safely accessible to the vehicle operator during travel. GPS and data from other navigational equipment is transmitted over a digital data network, preferably a fiber optic network, that is provided in a vehicle for distributing data among the various electronic devices on-board. Voice and data streams sent to, and received from, wireless networks operating in the area, e.g., a WWAN, WPAN or WLAN, are also distributed over the fiber optic network for use by various on-board devices. An antenna farm, for a GPS receiver and wireless transceivers, can be connected to the on-board data network.

Abstract: A method and apparatus for controlling the various functions of an internal combustion engine using a program controlled microprocessor having a memory preprogrammed with various control laws and associated control schedules, such as a fuel cut-off and reset system which responds to one of the selected fail signals receives information concerning one or more engine operating parameters such as manifold pressure, throttle position, engine coolant temperature, air temperature, and engine speed or period and the like. These parameters are sensed and then supplied to input circuits for signal conditioning and conversion to digital words usable by the microprocessor.

Abstract: A method and apparatus for controlling the various functions of an internal combustion engine using a program-controlled microprocessor having a memory preprogrammed with various control laws and associated control schedules receives information concerning one or more engine operating parameters such as manifold absolute pressure, throttle position, engine coolant temperature, air temperature, and engine speed or period and the like. These parameters are measured and then supplied to input circuits for signal conditioning and conversion to digital words usable by the microprocessor. The microprocessor system computes a command word indicative of a computer-commanded engine control operation and output circuitry responds to predetermined computer-generated commands and to the computed digital command words for converting them to corresponding pulse-width control signals for controlling such engine operations as fuel-injection, ignition timing, proportional and/or on-off EGR control, and the like.
