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. The load sensors may weigh from anything over 1 kilogram up to several tones of weight.
The load sensors may be located at any position in the vehicle such as on the chassis, the floor plan and/or on the axles of the vehicle, Alternatively, a mat may be used to be placed over the chassis or floor plan of the vehicle with load sensors then being mounted on the mat. 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. In the event that the load sensors indicate that excessive weight or above a pre-set value is being carried by the vehicle, then 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.
In alternative embodiments, 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.
The load sensors may aiso be used to monitor changes (e.g. position) of the load in the vehicle during transit. The variation in the measurement from the load sensor may therefore indicate that the load has become unstable during transit In the event that instability is detected, then a warning signal may be sent to the driver of the vehicle using the display unit using, for example, an audible and/or visual warning.
