Preferably, the sensor means is provided for mounting at a predetermined position or positions on the load support means and the computing apparatus is programmed with predetermined vehicle parameters to produce one or more of a plurality of computer outputs representing the load or loads applied to the load support means at one or more of a plurality of positions thereon remote from the predetermined position of the sensor means.
In a preferred embodiment of the invention, the sensor means comprises a first sensor for mounting on the load support means at a first position thereof and responsive to a variable of the load support means which varies with the load applied thereto at the first position to produce a first sensor output signal and a second sensor for mounting on the load support means at a second position thereof spaced from the first position and responsive to a variable of the load support means which varies with the load applied thereto at the second position to produce a second sensor output signal and the computing apparatus is programmed to produce the computer output or outputs from the first and second sensor signals and predetermined vehicle parameters.
According to a second aspect of the present invention, there is provided a vehicle including a load monitoring system according to the first aspect of the invention, the load support means comprising a chassis, front and rear wheeled supports supporting the chassis which extends therebetween and a load supporting body mounted on the chassis. The load supporting body may in a load measuring disposition thereof be supported totally by front body support means at the front of the body and by rear body support means at the rear of the body. With this arrangement, the vehicle parameters are then preferably obtained from measurements with the load supporting body in the load measuring disposition and the computing apparatus arranged to generate computer output when the load supporting body is in the load measuring disposition.
The rear body support means may be such as to allow for the raising of the front of the body and the front body support means may comprise hydraulic ram means for raising the front end of the body, whereby the body can be raised to the load measuring disposition in which it is totally supported by the rear support means and the hydraulic ram means.

The computing apparatus is then programmed to produce in response to the four sensor output signals a computer output representing the sum of the loads applied to the two sides of the chassis.The computing apparatus may, if desired, also be programmed to produce a computer output representing a difference in the loads applied to the two sides of the chassis to provide an indication of a lateral imbalance of the loads.
The front and rear wheeled supports of the vehicle may comprise front and rear wheel axle arrangements supporting front and rear road wheels, the vehicle parameters may include unladen vehicle front axle and rear axle loads, predetermined maximum laden vehicle front axle and rear axle loads and constants associated with vehicle geometry and the computing apparatus may be programmed to produce from the sensor output signals computer outputs representing the front and rear axle loads.
The computing apparatus may furthermore be programmed to produce a computer output representing the payload carried by the load carrying body from the front and rear axle loads and the unladen vehicle axle loads. In addition, the computing apparatus may be programmed to produce from the front and rear axle loads a computer output representing the gross vehicle weight.
The computing apparatus may comprise a control console mounted in the cab of the vehicle and including instruction keying devices for instructing the computing apparatus to produce any selected one or ones of a plurality of computer outputs and the display means may provide a digital display of the selected computer output or outputs. In addition, the display means may include front axle and rear axle display units each composed of light emitting diode bars arranged in a stack and the computer outputs representing the front axle and rear axle loads may produce a cumulative illumination of successive bars with increasing axle load up to illumination of all the bars, which indicates a maximum permitted axle load.
Two embodiments of the invention will now be described by way of example with reference to the accompanying drawings in which: Fig. 1 is a schematic side elevation of a motor vehicle embodying a load monitoring system according to the invention,
Fig. 2 is a scrap elevational view of part of the chassis of the vehicle shown in Fig. 1, fitted with a sensor of the monitoring system,
Fig. 3 is a cross-section of the part of the chassis shown in Fig. 2, taken on the line Ill-Ill in Fig.
2,
Fig. 4 is a block schematic diagram of the load monitoring system provided on the vehicle shown in Fig. 1, and Fig. 5 is a schematic front elevation of a control console and display unit of the monitoring system shown in Fig. 4 and mounted in the cab of the vehicle shown in Fig. 1.
Referring first to Fig. 1, a motor vehicle 11 comprises a chassis 12 supported by a pair of front wheels 13 and two pairs of rear wheels 14 and 15, a driver's cab 1 6 and a load carrying body 17 which is mounted on the chassis 12 by a transverse hinge 18 at the rear end of the chassis and a hydraulic ram 19 at the front end of the body, which can be raised by the actuation of the ram 19 to turn the body 1 7 about the transverse hinge 1 8 into a sharply inclined position for disposing of a load 20 contained in the body 1 7. In the position shown in Fig. 1, the load carrying body 1 7 is supported by the ram 19 in a slightly raised position in which it is totally supported by the ram 1 9 and the hinge 18. In a fully lowered position of the ram 1 9, the base of the body 1 7 rests on the chassis between the ram 1 9 and the hinge 1 8, thereby relieving the ram 1 9 from supporting the front of the body 1 7 during transportation of the load 20.
A pair of transducers 21 and 22 are mounted on the nearside of the chassis 12 in positions longitudinally spaced from each other and a further pair of transducers 23 and 24 are mounted on the offside of the chassis 12 in the same positions as those of the transducers 21 and 22. The transducers 21 to 24 are coupled to a microprocessor 25 housed in the cab 16 and including an operators control console and display unit 26 located in a position in the cab for easy operation and viewing by the driver of the vehicle.
Referring now to Figs. 2 and 3, each of the transducers 21 to 24 comprises a strain gauge 27 mounted on a strain link 28 secured to a web 29 of a longitudinal channel member 30 of the chassis 12 by bolts 31 and 32. The strain gauge 27 is connected in to one arm of a conventional temperature compensating bridge network and a compensating element, mounted in the same location as the gauge 27, is connected in an adjacent arm of the bridge network. A voltage is applied to the appropriate diagonal of the bridge and an output obtained from the other diagonal to produce a signal representative of the bending of the chassis member at the location of the strain gauge 27.
Referring now to Fig. 4, the output signals from the transducers 21 to 24 are amplified in amplifiers 33 to 36 and applied to separate input terminals of a multiplexer 37. The signals are in analogue form and the multiplexer provides for the serial transmission of them in separate time division channels through an analogue-to-digital converter 38. The analogue signals applied to the converter 38 are converted thereby to digital signals in an eight-bit code in parallel bit form suitable for feeding to the microprocessor 25. The digital signals are fed via a conventional peripheral interface adaptor unit 40 to the central processing unit 41 of the microprocessor, the interface adaptor unit 40 providing for modification of the digital signals into a form acceptable for use in the central processing unit 41. A further interface adaptor 42 under the control of the central processing unit 41 provides for switching of the converter 38. The microprocessor 25 includes a decoder 43, timer 44 and the control console and display unit 26. The decoder 43 preprocesses commands from the control console and display unit 26 and the timer 44 provides the necessary timing signals for multiplexer channel selection controlled by the central processing unit 41. The microprocessor 25 is arranged to be supplied with power from a vehicle battery 45 via a voltage converter 47 to provide 24 volt and 5 volt supplies.
Referring now to Fig. 5, the control console and display unit 26 is provided with a plurality of control push buttons for use by the driver of the vehicle in transmitting instructions to the microprocessor, a digital display 57, two further display devices 58 and 59 and a warning lamp 60, the functions of which will hereinafter be described.
The microprocessor 25 is programmed to produce computer outputs representing in digital form on the digital display 57 the front axle and rear axle loads upon depression of the push button 50 or 51, the gross vehicle weight upon depression of the push button 48, the payload carried by the vehicle body 1 7 upon depression of the push button 4S, the total of the payloads during the life of the vehicle upon depression of the button 53, the trip total of payloads carried throughout a period commenced by depression of the reset trip total push button 52, the load displayed on the digital display 57 being in
British or metric tons by appropriate depression of the push button 55.In addition, the computer outputs representing the front axle and rear axle loads are also displayed on display devices 58 and 59, each of which comprises a plurality of light emitting diode bars arranged in a stack and illuminated successively and cumulatively in response to increasing axle load and so calibrated as to show complete illumination of the stack when the computer output represents the maximum permitted axle load. The warning lamp 60 is arranged to be energised when the load displayed on the digital display 57 exceeds the maximum permitted or safe load.
To produce the above-mentioned computer outputs, the microprocessor needs to be programmed for calculating from the outputs of the four transducers 21 to 24 the front axle and rear axle loads. From the values of the front axle and rear axle loads the other computer outputs can readily be obtained by the microprocessor. In particular, the unladen weight of the vehicle is entered in to the microprocessor and the two axle loads added together and subtracted from the unladen weight to produce the payload carried by the vehicle. The front and rear axle loads may also be added together to produce the gross vehicle weight. The total of the payloads throughout the life of the vehicle may be obtained by a simple arithmetic operation and a read-out in British or metric tons can be obtained by applying a simple multiplication factor.
It is proposed in the present embodiment of the invention to programme the computing apparatus for calculation of the front axle and rear axle loads from transducer output signals obtained when the load carrying body 1 7 is in the slightly raised position as shown in Fig. 1 so that the body 1 7 and the payload are totally supported by the ram 19 and the hinge 18 and can be represented by point loads Ra and Rb. If the front axle reaction is taken to be Rf and the total rear axle reaction to be Rr then it can be shown that following calibration for the particular vehicle the front and rear axle loads can be calculated knowing only the values of the transducer output signals.
For calibration of the transducers 21 to 24 the vehicle is taken to a weighbridge. At the weighbridge, the vehicle 11 with the body 17 empty and in the slightly raised position is moved to a position in which the front wheels 1 3 rest on the weighbridge. The output signals from the transducers 21 to 24 are recorded as well as the unladen front axle load. The vehicle 11 is then moved to a position in which the rear wheels only are on the weighbridge and the unladen rear axle load measured and recorded. The vehicle with the body 1 7 still in the slightly raised position is then loaded with a payload providing maximum permitted front and rear axle loads, which are measured and recorded, together with the measurement and recording of the transducer output signals under this maximum loading.
The data obtained at the weighbridge is then used to calculate the constants in the equations for evaluating the front and rear axle loads from the transducer output signals and the constants programmed into the computing apparatus.
Equations for calculating the front and rear axle loads from the transducer output signals may be obtained as follows:- Let Ra=Ram cradle bracket point load Rb=Hinge bracket point load Rf=Front axle reaction
Rr=Total rear axle reaction
e,=Output signal of one of the front transducers 21 and 23
e2=Output signal of one of the rear transducers 22 and 24
k, k1, ..... . k32=Constants.
Taking moments about Rb Rak=R1k1+Rfk2 Ra=Rrk3+Rfk4 (1) taking bending moments:- e,=Rfk5Rak6 Substituting equation (1) for Ra in above equation: e1 =Rfk5k6(R,k3+Rfk4)
=Rfk5R rk7-Rfks (2)
.'. el=RfkS-Rrk7 Taking bending moments:- #2=Rfkt10Rak11 Substituting equation (1) in above equation
e2=Rfk,10k11FRrk3+Rfk4
=Rfk10-RrR12R-fk13 e2=Rk1 4-R,'r12 (3) Add equations (2) and (3) e1 +e2=Rfk15-Rrk16 (4)
Now, from equation. (2)
e, e1+Rrk7
Rf = k9 .-.Rf=e1k17+Rrk18
Substituting above equation for Rf in equation (4)
(e1+e2)=k15(e1k17+Rrk18-Rrk18
(e1+e2=k19e,+k20Rr-Rrk16
(e,+e2=e1k19+Rrk21 (e1 +e2)=e1k19=R,'r21 (5) k22e1 +k22e2-k23e1=R
Expanding equation (5) we have: k22e1 +k22e2-k23e1=rr e1k24+e2k22=Rr (5A)
The constants k24 and k22 can be found using simultaneous equations from data obtained at the calibration stage.Also from equation (2)
R1k,-e1
Rr=
k7
Rr=Rfk25-e1k26
Substituting above equation for Rr in equation (4) fe, + e2)=Rfk15-k18(Rfk25-k26e1)
=R*15-Rf27+e1k28 (6)
(e1+e2)-e1k28=R*29
k30(e1 +e2)e1k31=Rf Expanding equation (6) we have: k30e' +k30e2-k31e1=R k32e1 +k3Oe2=Rf (6A)
The constants k32 and k30 can be found using simultaneous equations from data obtained at the calibration stage.
The transducers 21 to 24 may if desired be located at positions on the chassis 12 different from those provided in the embodiment of the invention hereinbefore described and the choice of position will be limited to some extent by the configuration of the vehicle to which the monitoring system is applied. Furthermore, for some vehicle configurations it may be necessary or desirable to employ three transducer pairs arranged in longitudinally spaced relation on the chassis. Where three such pairs of transducers are employed the constants which appear in the equations relating transducer outputs e,, e2 and e3 to front and rear axle reactions Rf and Rr and which are dependent upon vehicle geometry may be calculated from calibration measurements of the transducer output signals for three different front axle and rear axle loads.
In an alternative embodiment of the invention now to be described, the front transducers 21 and 23 are replaced by a transducer pair mounted on the cradle bracket of the ram 19 for producing a transducer output signal e, representative of the ram load Ra The rear transducers 22 and 24 are likewise replaced by a transducer pair mounted on the brackets of the hinge 1 8 for producing a transducer output signal e2 representative of the load Rb acting on the hinge. Equations may readily be derived for the front and rear axle reactions Rf and Rr as functions of e, and e The
rear he equations are linear and of the form: Rf=e1k1-e2k2
Rr=e1k3-#2k4 where k1 to k4 are constants dependent on vehicle geometry.
The constants for the above equations can be found from two sets of values for Rf, Rr e1, and e2 obtained at the calibration stage. The constants thus obtained are then programmed into the computer for the calculation of computer outputs representing the front axle and rear axle loads.
During calibration and for the purpose of obtaining computer outputs the load carrying body 17 is moved to the slightly raised position as shown in Fig. 1 so that the load of the body 1 7 including the payload is applied at the ram 19 and the hinge 18 as point loads.
The microprocessor 25 is furthermore programmed with maximum permissible axle loads and gross vehicle weight to produce illumination of the warning lamp 60 when the vaiue of the digital display 57 exceeds the permitted value.
Other computer outputs may, if desired, be provided. For example, a charge per unit payload may be entered into the microprocessor 25 and a monetary charged related to the payload displayed at the control console and display unit 26. A display of the total number of tipping operations may also, if desired, be provided. A display may also be produced showing any imbalance of the load across the width of the chassis 12, making the driver aware of dangerously out-of-balance loads.
While the embodiments of the invention hereinbefore described have included a vehicle with a tipping body, the load monitoring system may if desired be used with a non-tipping vehicle. In this case, different equations would need to be solved by the microprocessor 25 and additional transducers may be needed to enable the constants of the equations to be determined.
The monitoring system may also be used on articulated vehicles with, for example, one of the transducers mounted in a king pin support for the vehicle. While the vehicle described with reference to
Fig. 1 includes a single front axle and a rear axle arrangement employing two rear axles the invention is equally applicable to vehicles with other axle configurations.
