Methods and systems are provided for preventing vehicle roll. In one embodiment, a method includes: determining a first switch state; determining a second switch state; evaluating the first switch state and the second switch state to determine whether a condition of a mechanical linkage between a range selection device and a transmission has occurred; and selectively generating at least one of a control signal to control an electronic park brake and a notification message based on the determination.

Methods and systems for preventing vehicle roll

A default-to-park mechanism for a transmission includes an output member, a rotatable plate, a latching mechanism, and a biasing member. The output member is rotatable to park, reverse, neutral, and drive positions. The rotatable plate is coaxial with the output member. The plate and the output member interfere with one another such that the plate is moved in a first direction of rotation by the output member and the output member is moved in a second direction of rotation by the plate. The plate is releasably held by the latching mechanism to prevent rotation in the second direction of rotation when the output member is in the reverse, neutral, and drive positions. The biasing member biases the plate to rotate in the second direction of rotation to return the output member to the park position when the plate is released by the latching mechanism.

Mechanism for vehicle transmission default to park

A hinge pillar assembly includes a hinge pillar including a panel. The panel including a body side outer door shut face and a defining an inner cavity and an access opening in communication with the inner cavity. The access opening is positioned in the body side outer door shut face and provides access to the manual park release actuator at least partially disposed in the inner cavity. The hinge pillar assembly further includes a cover removably coupled to the hinge pillar. The cover closes the access opening when coupled to the hinge pillar. The hinge pillar assembly further includes a manual park release actuator at least partially disposed in the inner cavity. The manual park release actuator is operatively coupled to a transmission and is configured to move relative to the hinge pillar to shift the transmission from a Park mode to an Out-of-Park mode.
