ABSTRACT:
A control system and method for controlling a vehicular automated transmission system having an internal combustion engine and a multiple speed transmission, is provided. The control system includes an ignition having an output that issues an ignition signal and a first control unit that operates the engine in response to receipt of the ignition signal. A second control unit receives input signals from various system sensors and process the signals according to logic rules to issue a command output signal. A relay interrupts transmission of the ignition signal to the first control unit in response to either the absence or receipt of the command output signal. The method includes the steps of determining if the automated transmission system is operating abnormally and interrupting transmission of the ignition signal to the first control unit when it is determined the automated transmission system is operating abnormally.
