Abstract
An apparatus and method is provided for an improved brake shift interlock system which reduces solenoid noise created by vehicle vibrations and solenoid activation. The brake shift interlock system includes a park position switch, a brake sensor, and a control circuit. The method includes the sensing of the park position switch and the brake sensor and generating a pulse width modulated control signal having a varying duty cycle for driving the solenoid when predetermined conditions of the park position switch and brake sensor are sensed.
