A recently granted patent (Publication Number: US11904764B2) discloses a cancellation device for an automotive feature on a vehicle. The device includes a lever that can be manually moved to actuate the automotive feature, a detent pawl coupled to the lever, a detent spring to bias the detent pawl, a centering spring to return the lever to a neutral position, and a magnet to hold the lever in a non-neutral position. The detent pawl is designed with a main body and shaft fixed to the lever, with symmetrical molded body and protruding pawl regions at each end.

Furthermore, the patent describes a module for the cancellation device, including a housing, detent spring, detent pawl, detent cams, and a magnet to hold the detent cams in place. The detent pawl is configured to slide relative to the housing and detent spring, with protruding pawl regions to contact the detent cams. The module also includes a turn signal stalk, an electromagnet, and a nulling coil to generate a force when deactivated. The detent cams have rotating arms and cam surfaces to facilitate detent action with the detent pawl. Overall, the patent details a sophisticated system for canceling automotive features efficiently and reliably.
