The present disclosure provides systems for microprocessors to control a transmission power relay output with a latchdown mechanism in the event that either microprocessor decides it is appropriate to de-energize the relay. Advantageously, the present disclosure allows, for example, the transmission control to be performed by an existing dual microprocessor configuration instead of a custom-designed application specific integrated circuit (ASIC). The microprocessor-based software is more easily updated or changed to add functionality. Further, the present disclosure minimizes unique development with respect to electronic transmission control with a less complex design.

Systems for providing an automobile electronic transmission control monitoring unit with a latchdown mechanism

A computer-implemented software development system is provided for constructing applications that are embedded in a microcontroller of a motor vehicle. The development system includes a data dictionary which stores data type information for a plurality of vehicle parameters and is able to generate a parameter definition file having data type information for each vehicle parameter associated with a first application. A calibration repository is used to generate a calibratable file for the first application, where the calibratable file includes calibratable vehicle information and controller executable instructions for the first application. The parameter definition file and the calibratable file are then used by a calibration tool to calibrate the first application in relation to a particular motor vehicle.
