Abstract
Presented are Brake Transmission Shift Interlock (BTSI) systems for vehicle powertrains, methods for making/operating such BTSI systems, and vehicles equipped with a BTSI system. A BTSI system for a motor vehicle includes a shifter solenoid with a solenoid body that mounts to the vehicle body, and a solenoid armature that is movably attached to the solenoid body to transition back-and-forth between locked and unlocked positions. The shifter solenoid is selectively operable via a brake control module to move the solenoid armature between the locked and unlocked positions to thereby block and unblock movement of a gear shifter from the park position, respectively. A position switch mounts to the vehicle body adjacent the shifter solenoid and detects the vehicle transmission being in a park mode. The position switch selectively mechanically engages with the shifter solenoid such that the solenoid armature, upon moving to the locked position, pushes closed the position switch.
