Abstract
A vehicle sensing system includes a data bus, a first microprocessor coupled to the bus and a plurality of sensor modules about a vehicle periphery for detecting the presence of objects within a predetermined range of distances of each of such sensor modules. Each sensor module of the vehicle sensing system includes a transducer, a second microprocessor, coupled between the transducer and the bus, for processing information received from the transducer, and a light emitting diode disposed on an outer surface of a housing for the transducer, coupled to the second microprocessor, for indicating when an object is within the predetermined distance of the sensor module or when the sensor module is faulty. Each sensor module further includes a temperature sensing circuit coupled to the second microprocessor and a bus transceiver for receiving information from the bus and for transmitting information to the bus.
