Abstract
Abstract A device for monitoring the systems of a truck has sensors for detecting the gas tank level, temperature of the driver's compartment, outside temperature, operating conditions of the engine and electrical system, and various parameters of the fluids and exhaust gas. Electrical conductors connect these sensors to a control unit which receives signals from the sensors. The device includes at least one additional sensor which is located in a wheel of the truck. This additional sensor comprises a hollow spherical jacket, and the outer surface of the jacket is provided with a foil designed to measure tire temperature and pressure. The inner surface of the jacket is coated with an electrically conductive layer and magnetic strips are embedded in the jacket near the inner surface of the same. An inner sphere of synthetic resin having a plurality of coils embedded therein rides on the inner surface of the jacket via ball bearings. The inner sphere includes a signal receiver, electronic processing unit and radio transmitter. The radio transmitter sends the control unit data on tire temperature and pressure as well as data on movement of the inner sphere. The tire temperature is used to monitor brake function while the tire pressure is used to monitor the weight of the cargo. Movement of the inner sphere is used to detect attampted theft of the truck. Depending upon the signals recieved by the control unit, the control unit can inhibit starting of the truck, shut off the engine, generate an alarm and generate indications of malfunctions.
