dual mode sensor whereby, in a first, clear visibility, mode,
the system emits a warning signal only when either an object
is standing in the vehicle’s driving path or the object is
moving in the same direction as the vehicle but at a slower
speed and, in a second, poor visibility, mode, a warning
signal is emitted not only in the same situations described
with regard to the clear visibility mode, but also when an
object is determined to be coming toward the vehicle. The
dual mode is said to allow a driver more flexibility in
determining when it is actually necessary for a warning signal
to be emitted depending on the visibility mode selected.
Representative independent claim 5 is reproduced as
follows:
5. An object sensing device for a motor vehicle,
comprising at least one transmitter/receiver pair operatively
located in the motor vehicle to obtain a reflex signal from an
object situated in a driving direction of the motor vehicle
and having a first operating mode for clear visibility and a
second operating mode for poor visibility, wherein the at
least one transmitter/receiver pair is operatively configured
such that a signal emission occurs for the first operating
mode when an object is standing or is driving more slowly in
the driver's direction of the motor vehicle, but not when an
object comes toward the motor vehicle and, for the second
operating mode, when an object is standing or is driving more
slowly in the driver's direction of the motor vehicle and when
an object comes toward the motor vehicle.
