Abstract
A sensor assembly for a vehicle electronic braking system including a housing, at least one linear sensor, the at least one sensor contained within the housing, the linear sensor adapted to measure the linear distance traveled of a brake pedal. The assembly further includes a rotary sensor, the rotary sensor also contained within the same housing, the rotary sensor adapted to measure rotary motion of a DC motor in an the electronic braking system. The rotary sensor and the at least one linear sensor each in communication with a brake control unit. The at least one linear sensor and the at least one rotary sensor is encapsulated, either together or separately. The at least one linear sensor is a Hall-effect sensor. A wake up switch circuit is integrated with at least one of the linear sensors to wake up the system when the driver depresses the brake pedal in the electronic braking system. The rotary sensor is an inductive sensor.
