Abstract

See full text

In general, a shift-by-wire transmission range selector system consistent with the present disclosure may include an actuator one or more electric motors to allow the actuator to operate for shifting the gear position of a transmission. In the event of a power or system failure, a fail safe release motor may be actuated by energy stored in a capacitor. The fail safe release motor drives a slide cam to release a trigger arm. Upon release of the trigger arm, a spring-driven mechanism safely returns the transmission to the PARK position by rotating an output shaft. A redundant control link may be provided, configured to actuate the fail safe release motor in the event of a power or system failure.
