초록 ▼

An obstacle proximity warning device for vehicles having an ultrasonic transceiver, for sending an ultrasonic signal and receiving the ultrasound reflected by an obstacle, a receiver signal process means connected to the ultrasonic transceiver, to generate trigger signals upon a threshold level signal being received from the ultrasonic transceiver, an alarm means responsive to the trigger signals, a housing in which the ultrasonic transceiver is mounted and a mounting bracket for fixedly mounting the housing to the vehicle. The mounting bracket has a resilient coating adapted to substantially absorb ultrasonic vibrations generated by the ultrasonic transceiver, to prevent the radiation of ultrasonic vibrations from other elements of the vehicle or the mounting bracket.

[ What is claimed is:] [1.] An obstacle proximity warning device for vehicles, comprising:an ultrasonic transceiver to send an ultrasonic signal and to receive the ultrasound reflected by an obstacle;a receiver signal process means pre-amplifier connected to said ultrasonic transceiver;an amplifier connected to said pre-amplifier;a threshold detector connected to said amplifier, said threshold detector being arranged to generate trigger signals upon a threshold level signal echo being received from said ultrasonic transceiver;an alarm means responsive to said trigger signals;a housing in which said ultrasonic transceiver is mounted;a mounting bracket for fixedly mounting said housing to the vehicle; where said mounting bracket has a resilient coating adapted to substantially absorb ultrasonic vibrations generated by said ultrasonic transceiver, and where said alarm means comprises a control means for processing said trigger signal from said threshold detector, to permit different types of alarm indications for different trigger signals, said control means comprising a microprocessor with associated circuits, said microprocessor running a predictive window filtering scheme program using two previous said echoes detected with said transceiver to verify that a latest received echo falls in a window of time that corresponds to a rate of change in said previous two echoes, and if said latest echo is valid, then said predictive window is shifted to reflect a new object position.
