Definitions

  • the present invention relates to a vehicle load sensing system More particularly, the present invention relates to a vehicle load sensing system capable of measuring and/or monito ⁇ ng the weight of a load being carried in a vehicle
  • the present method of measuring loaded vehicles involves driving the vehicle onto a weighing device such as a permanent or portable scale (e g a weigh b ⁇ dge)
  • a weighing device such as a permanent or portable scale (e g a weigh b ⁇ dge)
  • the scale gives the amount of load on each wheel or on each axle, depending upon how it is constructed
  • a vehicle load sensing system comprising: at least one load sensor located on a vehicle; display means located in the vehicle; wherein the at least one load sensor is capable of measuring and/or monitoring the load being carried in the vehicle and displaying the measured/monitored level on the display means.
  • the present invention therefore uses load sensors mounted on a vehicle which allow a measurement to be made of the weight being carried by the vehicle. This measurement may be done when the vehicle is being loaded so that a maximum safe weight is not exceeded and so that the maximum weight may be carried and transported safely. Continuous measurements may also be made as the vehicle is moving to detect any movement in the load which may lead to a safety hazard.
  • There may be at least one or more load sensors such as two or more or a plurality of load sensors.
  • the load sensors may be as known to the person skilled in the art and may be as defined in US 6,272,936 which is incorporated herein by reference.

On measurement of the weight of the load being carried by the vehicle, the load sensors may then transmit this information to a central processing unit which then processes the received information. The processor unit may then transmit the information to a display means mounted in, for example, the cab or driving area of the vehicle. The display unit may therefore display the weight of the load being carried by a vehicle in, for example, a graphical display using coloured bars or alternatively using a numerical readout.
  • the processor may be connected to the display unit using a hard wired electrical connection means or alternatively may use a wireless connection.
  • a warning signal may be sent to a driver of the vehicle.
  • the warning signal may be either in a visual form and/or an audible warning.
  • the display unit may be a standard mobile phone that has a suitable wireless connection.
  • the information transmitted to the display unit may also then be forwarded to a further information point such as in any other country allowing central control of a number of vehicles.
  • This information may be transmitted using, for example, a Global Positioning System (GPS) connection.
