  • Electronic controller for an automatic transmission
    Patent number: 4998200
    Abstract: An electronic controller, for use in an automatic transmission control system, for controlling solenoid-actuated valves to control the flow of hydraulic fluid throughout the transmission thereby allowing gears and friction elements to cooperate in response to various input signals, allowing the entire system to be adaptive to changing load demands placed on the vehicle.

  • Utilization of a reset output of a regulator as a system low-voltage inhibit
    Patent number: 4992951
    Abstract: A circuit for the provision of low-voltage inhibit by using a reset output of a regulator with the enablement of a reset signal to the microcomputer unit in response to a "key-on" signal and a reset condition of the switchable output of the regulator thereby providing an additional reset mode from the switchable voltage supply in the regulator that is gated out to reset the microcomputer unit only in response to a "key-on" condition and a reset condition from the switchable voltage output of the regulator.

  • Shutdown relay driver circuit
    Patent number: 4991096
    Abstract: A circuit to provide a shutdown relay driver circuit utilizing a self protecting high side switch configured such that if a short to ground occurs, a default mode is selected to provide a means to pull down the output voltage to ground regardless of the electrical state of the relay.

  • Open loop control of solenoid coil driver
    Patent number: 4980793
    Abstract: An electronic driver circuit for the open loop control of the energization of a solenoid coil, forming part of an electromagnetic solenoid actuator valve, in response to a control pulse produced by a control circuit and where the predetermined schedules are a function of the inductance and resistance of the coil, the desired peak output voltage from the coil and the desired average holding current through the coil.

  • Method of determining the continuity of solenoids in an electronic automatic transmission system
    Patent number: 4939928
    Abstract: A method of determining the continuity of solenoids in an electronic automatic transmission system wherein a controller is programmed to determine solenoid continuity by checking for the presence of an inductive "OFF" spike which results from an open circuit or a direct short to supply voltage from the solenoid of the solenoid-actuated valves.

  • Throttle position sensor data shared between controllers with dissimilar grounds
    Patent number: 4901561
    Abstract: A circuit for throttle position sensor data shared between controller with dissimilar grounds and to provide reading the output of the throttle position sensor with one of the controllers by referencing the output to the ground of that controller to generate an absolute throttle position sensor reading; and reading the output of the throttle position sensor with another controller via a differential amplifier to generate a relative throttle position sensor reading.

  • Programmed spark scatter control method for quick response to changing load conditions
    Patent number: 4719573
    Abstract: In an idle speed control system for an engine equipped with a fuel/air mixture means and an air bypass means or movable throttle stop means, the idle speed can be quickly moved to the desired value by temporarily changing the spark advance and holding the changed spark advance until the air bypass system or movable throttle stop means has had a chance to respond to the various demands of the idle condition.
