Abstract
An automotive opto-electric starter interlock for use in a motor vehicle for the purpose of preventing the engine from being remotely started unless the transmission is in neutral. The starter interlock includes an optical sensors array mounted to the transmission shift linkage. The output of the sensors is dependent upon the position of the shift linkage, hence allowing to determine if the transmission is in neutral. A microprocessor stimulates the sensors and observes their response to determine the position of the shift linkage. The information supplied by the sensors is also used to detect system malfunctions.
