Abstract: A linear position sensor that includes a plurality of Hall effect transducers enables reliable positioning of a parking brake cable. Coarse positioning sensing is provided by longitudinally spacing the Hall effect transducers such that not more than one transducer has a positively sloped output signal for a given position of a magnet connected to a parking brake cable actuator. Fine position sensing is provided by linear approximation of the output signal with an offset appropriate for the specific transducer having the sensed positively sloped output signal.

Abstract: An intelligent input push rod assembly for applying an input force from a brake pedal to a power booster of a brake system. The input push rod assembly includes a sensor that is capable of generating an electrical output having a magnitude that varies with the amount of force applied to the input push rod by the brake pedal. Preferably, the sensor generates an output voltage signal that is generally proportional to the input force applied to the input push rod. A shunt is provided so that springs associated with the sensor operate in a generally linear force-deflection operating range of the springs. The output signal generated by the sensor is applied to a brake light control system that is supported by the input push rod assembly. The brake light control system uses the signal generated by the sensor to determine whether the vehicle brake lights should be illuminated and also to cause direct illumination of the brake lights during a braking operation.

Abstract: A brake caliper comprises a motor having a shaft, at least one first planetary gear, and at least one second planetary gear. The at least one first planetary gear is rotatably engaged with the shaft and with a piston, and is operatively engaged with a first carrier. The at least one second planetary gear is operatively engaged with the first stage carrier and with a second carrier. A ball screw is engaged with the second stage carrier for rotation therewith, and a ball screw nut is operatively engaged with the ball screw. A parking brake for the caliper is also provided.

Abstract: A method is directed to controlling an electric caliper brake system. The method provides for receiving an ignition voltage signal, receiving a caliper position signal, sending a motor shut down signal, sending a back drive control signal based on the received ignition voltage signal and the caliper position signal, and releasing stored energy from a non-linear device to a caliper brake system motor responsive to the back drive control signal. The non-linear device may be implemented as a capacitor. The step of sending a back drive control signal based on the received ignition voltage and the capacitor position signal includes analyzing the ignition voltage signal for an ignition voltage failure, analyzing the caliper position signal for caliper engagement, and transmitting the back drive control signal responsive to the ignition voltage failure and caliper engagement. Ignition voltage failure occurs when the ignition voltage signal is a low value.
