ABSTRACT:
A vehicle obstacle detector (10) that is designed to alert the driver of a motor vehicle that the vehicle has encountered an obstacle. The detector (10) consists of an obstacle detector assembly (12) that includes a front probe (14) having a cavity (14b) that houses a piezoelectric element 14c. The probe (14) is attached to a flexible housing (16) that can be attached by means of a clamp (20) to the curb side of a vehicle or alternatively, the detector can be mounted to a wall (60) of a structure. The probe (14) produces electrical oscillations when the probe touches or scrapes against an obstacle. The oscillations are applied to an electronics control unit (30) that subsequently produces an alarm signal that energizes a visual and/or an audio alarm. The alarm may be located in the cab of a vehicle or on the wall when a wall mounted assembly (12) is employed.
