Abstract
A Brake Transmission Shift Interlock and Park Lock System having a shift lever, electromagnetic device, and blocking member operating with reverse logic. The system includes disabling means for disabling operation of the electromagnetic device when the shift lever is moved out of the PARK position and overriding means for manually withdrawing the blocking member from a position blocking the movement of the shift lever out of the PARK position. A time delay circuit decreases the speed of blocking member movement from the blocking position to the withdrawn position. A wire harness, including a park detection switch, electrically connects the BTSI to an automotive electrical system.
Claims13
A brake transmission shift interlock comprising:
- a blocking member having a first position and a second position;
- a spring for biasing the blocking member toward the first position;
- actuation means for moving the blocking member against the bias of the spring to the second position in response to an input signal;
- and
- time delay means for controlling a speed of blocking member movement as the blocking member is moved from the first position to the second position.
