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.

An improved vehicle obstacle detector and alarm system (10) consisting of an obstacle detector assembly (12) and an electronic control unit (40). The assembly (12) includes an impact probe (14) that is attached through a flexible rod (16) to the front end (18A) of a housing (18). The housing includes at its rear end (18B) an acoustic transducer cavity (18D) into which is inserted a piezoelectric acoustic transducer (26) that is attached to the first end (20A) of a coaxial cable (20). The second end of the cable (20) is attached to an female connector (22) that interfaces with a male connector (41) on the electronics control unit (40). When the impact probe (14) encounters an obstacle, a series of mechanical oscillations are produced that are mechanically transmitted through the flexible rod (16), the housing (18) and ultimately to the piezoelectric acoustic transducer (26). The transducer (26) produces a series of electrical pulses, corresponding to the mechanical oscillations, that are then applied through the cable (20) to the electronics control unit (40). The unit (40) processes the electrical pulses and subsequently provides an alarm signal that energizes an audio and visual alarm that alerts the driver of a motor vehicle when the vehicle has encountered an obstacle.
