Abstract
A pedestrian impact sensor system includes a first plate and a second plate both connected to an outer surface of a vehicle such that a capacitance between the first plate and the second plate is dependent upon whether a body proximate the vehicle is animate. A crush sensor senses a force exerted by the body on the vehicle. A monitoring circuit monitors the capacitance between the first plate and the second plate and an output signal of the crush sensor. The monitoring circuit issues a safety countermeasure signal dependent upon the capacitance between the first plate and the second plate and the output signal of the crush sensor.
