20110144854 | SELF TESTING SYSTEMS AND METHODS - A diagnostic system for a vehicle comprises a diagnostic module, a control module, and a hardware interface module. The diagnostic module selectively diagnoses a fault in one or more of components that are integrated within a housing. The control module receives a request for testing of the diagnostic module and retrieves predetermined fault data corresponding to the fault. The hardware interface module receives component data for the diagnosis and the predetermined fault data, disables provision of the component data to the diagnostic module, and provides the predetermined fault data to the diagnostic module for the diagnosis. | 06-16-2011 |
20120245811 | TRANSMISSION SYSTEMS AND METHODS - A method includes: receiving M solenoids, each marked with a unique one of M identifiers, where M is an integer greater than one; receiving M lookup tables associated with respective ones of the M identifiers, wherein each of the M lookup tables establishes a relationship between input current and output pressure for only one of the M solenoids; assembling a transmission with a selected one of the M solenoids; selecting one of the M lookup tables based on one of the M identifiers marked on the selected one of the M solenoids; storing the selected one of the M lookup tables in memory of a transmission control module of a vehicle that is assembled with the transmission; and controlling output pressure of the selected one of the M solenoids based on the selected one of the M lookup tables and the input current using the transmission control module. | 09-27-2012 |
20130162183 | ELECTROLYTIC CAPACITOR REFORMATION SYSTEMS AND METHODS - An electrolytic capacitor reformation system for a vehicle includes an electrolytic capacitor, a motor driver module, a switching device, a resistor, and a switching control module. The electrolytic capacitor receives power from a battery of the vehicle. The motor driver module receives power from the electrolytic capacitor and drives an electric motor of the vehicle. The switching device and the resistor are connected in series in a current path between the battery and the electrolytic capacitor. The resistor limits current flow through the current path. The switching control module selectively transitions the switching device to a closed state to reform the electrolytic capacitor. | 06-27-2013 |
20130234568 | STEPPER MOTOR WITH COMMON SOLENOID CURRENT DRIVER - A stepper motor assembly includes a unipolar winding stepper motor, four drivers, and a transmission control module. The stepper motor has four coil parts. Each driver has a transistor connected to one of the coil parts. Each driver is operable to drive a phase of the stepper motor, where first and second phases are opposites of each other and third and fourth phases are opposites of each other. The transmission control module houses the four transistors. A transmission is also disclosed that includes the disclosed stepper motor assembly. | 09-12-2013 |
20150022215 | SYSTEM AND METHOD OF USING FLEXIBLE ECU INPUTS TO SPECIFICALLY DETERMINE THE TYPE OF ELECTRICAL FAULT ON AN INPUT - A control module includes an input module configured to operate in a normal operating state and a fault diagnosis state. The input module receives an input signal from a circuit module and generates a voltage based on the input signal. In the normal operating state, a fault diagnostic module determines whether the voltage is in a first range or a second range. The first range and the second range indicate that a fault is detected in the circuit module. The fault diagnostic module determines that the detected fault is a first fault type if the voltage is in the first range, transitions the input module from the normal operating state to the fault diagnosis state if the voltage is in the second range, and determines whether the detected fault is a second fault type or a third fault type based on the voltage in the fault diagnosis state. | 01-22-2015 |
20150211467 | DRIVER OUTPUT ENCODING SYSTEMS AND METHODS - A starter relay connects a battery with a starter motor of an engine when in a closed state and disconnects the starter motor from the battery when in an open state. A switching device provides current to the starter relay when in a closed state and disables current flow to the starter relay when in an open state. For an engine startup event, a switch control module: transitions the switching device to the closed state for a first predetermined period; transitions the switching device to the open state for a second predetermined period after the first predetermined period; and transitions the switching device to the closed state for a third period after the second predetermined period. The starter relay remains in the open state during the first predetermined period and transitions to the closed state when the switching device is in the closed state for the third period. | 07-30-2015 |
