Abstract
An object sensing device and method for a motor vehicle utilizes one or more transmitter/receiver pairs to obtain a reflex signal from an object from an object situated in front of the motor vehicle in terms of the driving directions. In a first operating mode for clear visibility, a reflex signal is emitted for the object when it is standing still or driving more slowly relative to the motor vehicle containing the device. In a second operating mode for poor visibility the reflex signal is additionally emitted when the object is sensed as coming toward the motor vehicle.
