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.
