ABSTRACT:
An inertia brake is coupled to a rotating shaft of a vehicle transmission where a ball ramp actuator energized by an electrical coil is used to load a clutch pack which frictionally creates a braking torque on the rotating shaft to facilitate synchronous gear engagement. A control system includes an electronic control unit and an inertia brake controller where a variety of sensors provide signals to the electronic control unit uses the sensor signals to generate a deceleration signal to the inertia brake controller which in turn generates and supplies the appropriate level of electrical current to the electrical coil which is used to energize the ball ramp actuator thereby accurately controlling the rate of shaft rotational deceleration.
