A pre-crash assessment system 1 includes a host vehicle 3 in motion. A
remote sensor 4, status monitoring sensors 5, and safety device actuators
are coupled to the host object. The remote sensor 4 detects target object
dynamics. The status monitoring sensors 5 detect host object dynamics. The
safety device actuators activate safety devices. A threshold for each
safety device actuator is defined by a safety device activation
specification. A safety device controller 10, also coupled to the host
object, generates tracking signals based on host object and target object
dynamics. The safety device controller 10 also estimates future positions
of the host and target objects, and estimates whether the potential for
crash between the host and target objects is within the threshold criteria
for specific safety device actuation. The controller 10 then controls the
safety device actuators when the potential for crash is within the
pre-determined threshold criteria.
