Abstract:
A method for operating a transmission system comprising:operating a gearshift; rotating a transmission manual shaft in response to operating said gearshift; generating a pulse-width modulated signal from a non-contacting transmission range sensor, said pulse-width modulated percent duty cycle signal varying in a proportional relationship to an angular position of said manual shaft gearshift relative to gearshift detent valleys and detent peaks; and receiving said pulse-width modulated percent duty cycle signal in a powertrain control module; determining, in said powertrain control module, said angular position of said gearshift by comparing said pulse-width modulated percent duty cycle signal to discrete duty cycle values preset in said powertrain control module; and operating vehicle functions in response to signals from said powertrain control module; operating a powertrain control module in response to said pulse-width modulated signal.
