Definitions

  • This invention relates to a system for monitoring the load on a road vehicle.
  • the invention is concerned with the disposition of a load sensor or sensors so as to supply to a control processor a sensor signal from which the required vehicle load parameters may be accurately determined.
  • a load monitoring system for a road vehicle comprising a strain sensor for mounting on a single-wheeled axle of the vehicle, or on a support member of the vehicle at a position which is at a substantially fixed or determinable distance with respect to the load to produce a sensor output which varies with the magnitude of the load, and a computing apparatus which is operable to process said sensor output and to produce in response thereto at least one computer output representative of a required load parameter of the vehicle and visual display means for producing a visual representation of said computer output.
  • the strain sensor preferably comprises one or more strain gauges mounted on a strain link which is mountable at the specified position on the vehicle.
  • the computing apparatus is preprogrammed in accordance with predetermined functions which establish the relationship between loads on the vehicle and the affect which is detectable as strain at such specified position or positions for the strain sensor.
  • the computing apparatus is also preprogrammed with such parameters as the vehicles' unladen weight, and is adapted to perform the required calculations using these preset parameters and the determined load value to provide the required load parameters.
  • Means may be provided for storing the calculated values for these load parameters for record or vehicle log purposes.
  • the present invention is concerned with the problem of providing an indication of the vehicle load with compensation being made for the amount of fuel carried in the vehicle's fuel tanks.
  • a load monitoring system for a road vehicle including sensor means for mounting on the vehicle for providing a sensor output which varies in accordance with the load carried by the vehicle, and a computing apparatus which is operable to process said sensor output and a signal representative of the amount of fuel in the vehicle's own fuel tank or tanks, to provide a computer output representative of the value which a load parameter of the vehicle would assume if there were a predetermined amount of fuel in said tank or tanks, and a visual display means for producing a visual representation of the computer output.
  • the computer means is adapted to provide axle and gross vehicle weights for full fuel tank conditions.
  • the computer is programmed with data indicative of the maximum fuel tank capacity and can calculate the difference at any time between this maximum and the current amount of fuel being carried. It can then calculate the weight of fuel which could be added to the tank, and adjusts the calculation of the load parameter in accordance with this calculated weight.
  • the reading on the visual display means always gives the driver the value for the load parameter (e.g. gross vehicle weight) as if the vehicle's tank or tanks were full, so avoiding later unintentional overloading through refuelling.
  • the invention is concerned with the problem which arises when, as is very common, a vehicle is loaded on sloping ground. Even if an on-board load monitoring system is provided, if the calculations made automatically for determining axle and gross vehicle weights using strain sensor outputs assume incorrectly that the vehicle is on level ground, a problem arises when the vehicle actually does move onto level ground and the load distribution between the vehicle's axles changes.
  • FIGS. 12a and 12b of the accompanying drawings show a two-axled commercial vehicle V on a horizontal surface and on a slope at an angle 0 to the horizontal, respectively.
  • the centre of gravity of the vehicle is at a point P, and it will be seen that the ratio of the distances, measured horizontally between the centre of gravity and the front and rear axles changes from AT - Br for the horizontal condition to Ai - Bi for the inclined condition. Accordingly, the ratio of the front to rear axle weights will also change.
  • the measurement of axle weight on a slope is not valid for the horizontal vehicle position, which is the position in which the vehicle load parameters would be checked on a weighbridge. Overloading could thus occur if a vehicle is loaded up to a given axle weight measured on a slope, and then driven onto a horizontal surface.
  • a load monitoring system for a road vehicle comprising at least one first sensor for mounting on the vehicle for providing a sensor output which varies in accordance with the load carried by the vehicle, a second sensor for mounting on the vehicle for providing a sensor output indicative of the inclination of the vehicle to a datum, e.g. the horizontal, a computing apparatus which is operable to process the sensor outputs from said first and second sensors to provide at least one computer output indicative of the value which a load parameter of the vehicle would assume when said inclination to said datum is zero, and visual display means for producing a visual representation of the computer output.
  • the second sensor is preferably an inclinometer which can be mounted on the vehicle chassis, the inclinometer having a casing, a pendulum member suspended within said casing, and means which provides a signal which varies in accordance with the angular relationship between the casing and the pendulum.
  • inclinometers are commercially available.
  • Figure 1 is a partly schematic diagram illustrating the basic components of a load monitoring system for a road vehicle according to the present invention
  • FIG. 2 is a block schematic diagram of the CPU of the system shown in Figure 1 ;
  • Figure 3 illustrates a strain link and the preferred process of attachment of the strain link to a load bearing member of a vehicle

  • a commercial road vehicle 1 to which a system 2 according to the present invention is applicable comprises an articulated lorry having a tractor unit.3 and a trailer 4 attached to the tractor unit 3 by means of the "fifth wheel" 5.
  • the tractor unit 3 has a chassis 6 supported by a front pair of single wheels 7 on a front axle 8 and a rear pair of double wheels 9 on a rear axle.
  • Mounted on the chassis 6 is a driver's cab 11 and a fuel tank 12.
  • a strain sensor 13 is mounted on the front axle 8 for detecting the strain in the front axle, a fuel sensor 14 is mounted on or in the fuel tank 12 for detecting the amount of fuel in the tank, and an inclinometer 15 is mounted on the chassis for detecting the inclination of the vehicle to the horizontal.
  • the strain sensor 13 comprises a pair of conventional strain gauges 28 fixed to upper and lower surfaces of a strain link 29 which is secured to the vehicle's front axle 8.
  • a strain link 29 which is secured to the vehicle's front axle 8.
  • opposite ends of the strain link are securely bolted to respective ones of a pair of support feet 30, and these feet are welded to the axle 8.
  • the fuel sensor 14 and the inclinometor 15 can each be of a conventional type.
  • the signals from the three sensors are routed via the junction box to the control unit 16 which has a plurality of input lines 33 for receiving these sensor signals.
  • a cable 34 between the control unit and the consol 21 comprises a number of lines which carry control signals generated in response to the operation of the buttons 24 to 27, to the microprocessor, and a plurality of output lines from the microprocessor for controlling the display panel 22 and mode indicator 23.
  • the mode indicator 23 is controlled to display a character indicating the present display mode.
  • the system automatically runs through a cycle of load parameter displays.
  • the sequence of display may be: front axle weight; rear (or drive) axle weight; total tractor weight; fifth-wheel load, each parameter being identified by a given digit display by the mode indicator.
  • the microprocessor 20 is preprogrammed with the legal requirements applicable to the particular vehicle concerned, and responds to any particular load parameter exceeding the relevant threshold by interrupting the sequence and providing a visual warning of the overload condition.
  • the warning comprises the repeated flashing of the mode display digit for the offending load parameter. When this occurs, the sequence may be resumed by a further operation of the weight button 25.
  • the "reset" button 24 allows for the resetting of the unladen weight of the vehicle.
  • the microprocessor is programmed with a value for the unladen weight which includes a statistical average weight of a commercial vehicle driver, greater precision for this factor for the particular driver concerned can be provided by this "reset" facility. * When the driver operates the reset button when seated in the cab, the system is reset so as to identify the current calculated vehicle weight as the new unladen weight.
  • the system provides two calibration functions which can be selected by operation of the calibration button 26, followed by another one of the function buttons. T&e first of these functions is an initialization Operation which is carried out when the system is first installed in the vehicle for the purposes of calibration of the various different sensors.
  • the program in the microprocessor assumes that the outputs of the sensors will have certain predetermined values under given load and vehicle conditions, and this initialization procedure is necessary to establish this calibration of the sensors.
  • the "weight" button 25 is operated to select the different sensors in a predetermined sequence, the selected sensor being identified by the display of the mode indicator 23. For each selected sensor, a zero condition corresponding to a predetermined load or vehicle condition is established.
  • Adjustments are made to set both the sensor output, and the amplified sensor output to zero in this predetermined condition.
  • a predetermined non-zero condition is then applied, and the relevant amplification factor is adjusted to provide the required predetermined output. This procedure is repeated for each sensor in turn.
  • the system can be made to perform a self-checking routine.
  • the vehicle is placed under standard conditions, e.g. on level ground with no load, and the calibration button 26 is operated, followed by a predetermined sequence of the other buttons.
  • the system reads the sensor outputs in a predetermined sequence and compares them with predetermined reference values stored in the microprocessor memory. If any of the measured values is beyond a predetermined tolerance with respect to the respective reference value, the sensor reading is repeatedly flashed on the numerical display 22 to give a visual warning.
  • the mode indicator 23 identifies the particular sensor concerned. The relevant sensor and/or amplifier adjustment can then be made to bring the system back into calibration.
  • the microprocessor may also be arranged to provide a burglar alarm function.
  • the system can be put into the alarm mode by a predetermined sequence of operation of the function buttons.
  • the system is thereafter inactive for a short period which is sufficient to enable the driver to leave the cab.
  • the system is responsive to any sudden change in the output of the load sensor by an amount exceeding a predetermined limit to operate an audible and/or visual alarm.
  • the vehicle's horn may be operated and headlights may be flashed.
  • a predetermined delay between detection of the load increase and operation of alarm is provided in order to enable the driver reentering the cab to deactivate the alarm system by inputting a predetermined code comprising the original, or a different, sequence of operation of the function buttons.
  • the system may also respond to sudden changes in the supply voltage from the battery, as would be caused by the automatic switching on of an internal light in the trailer upon unauthorised opening of the trailers rear door.
  • the microprocessor may also be arranged to operate in conjunction with the distance measuring element of a Tachograph 45 which is a time distance measurement and recording device.
  • the system can be operated to provide the driver with information as to his compliance with the legal requirements of maximum driving hours in a predetermined period, and this information can be retrieved in combination with the weight variables to provide a record for management purposes of time, distance, fuel, weight and unauthorised activity.
  • the microprocessor is adapted to compensate for the current fuel level in the vehicle tank or tanks and to drive the numerical display 22 to provide a visual output corresponding to the full-tank condition. It will be appreciated that commercial vehicles have large-capacity fuel tanks and that accordingly if the vehicle is loaded up to the legal limit with the fuel tank significantly less than full, subsequent refuelling will put the vehicle into an illegal load condition. Accordingly, by compensating for the fuel level, the present system avoids this problem. To provide this function, the microprocessor 20 is programmed in accordance with theknown relationship between amount of fuel in the vehicle tank 12 and the affect which the load corresponding to that amount of fuel has upon the load sensor 13. The microprocessor can calculate the difference between the maximum capacity of the fuel tank and the current fuel level, the corresponding weight of the fuel which could be added to the fuel tank, and an appropriate compensation factor to be applied to the sensor output.
  • the load parameters displayed on the numerical displayer 22 always correspond to the full-tank condition of the vehicle.
  • the output of the load sensor or sensors for a given vehicle loading is affected significantly by the inclination of the vehicle to the horizontal, as previously described with reference to figures 12a and 12b.
  • the legal limits for the load parameters are set for a horizontal disposition of the vehicle, but it frequently happens that loading-up of the vehicle takes place in an ,inclined position of the vehicle.
  • the microprocessor in the embodiment of the present invention is programmed to compensate for any inclination of the vehicle to the horizontal so that the readings provided on the numerical display correspond to the values which the load parameters would assume in the horizontal position of the vehicle.
  • the microprocessor is programmed in accordance with the known geometrical configuration of the vehicle and the predeterminable functions relating the vehicle inclination to the change in the affect of the vehicle weight and the load on the load sensor or sensors.
  • a main fuel tank and an auxiliary fuel tank On some commercial vehicles there is both a main fuel tank and an auxiliary fuel tank. In a parallel fuel delivery system, these two tanks are connected in parallel so that their respective fuel levels are always the same. In this case, a fuel sensor output from one of the tanks provides the microprocessor with sufficient information for it to establish the current total fuel level and the compensation to be applied.
  • the auxiliary fuel tank is carried on top of the main fuel tank, its contents being emptied into the main fuel tank when the fuel level in the latter drops to a predetermined level. In this case, the low fuel condition of the main tank is signalled to j the driver, who then operates a switch to open a valve which dumps the fuel from the auxiliary tank into the main tank. To provide sufficient information to the microprocessor 20 in such an arrangement, the fuel sensor
  • the microprocessor 14 senses the fuel level in the main tank, and a simple electronic detector detects whether the auxiliary tank is full or empty.
  • the microprocessor is programmed with the fuel capacity of the auxiliary tank and can respond to the output of the electronic sensor to determine whether or not this amount of fuel is present in addition to the amount of fuel indicated by the fuel sensor output.
  • FIG. 5 illustrates another situation producing inaccurate sensing of twin-wheeled axle weight.
  • the vehicle has been parked with the left outer wheel resting on a kerb 48, and it can readily be seen that the leverage applied at the sensor 13 would be greater than in the case when the vehicle is supported on a flat surface because all of the weight applied by the left pair of wheels is imposed through the outermost wheel.
  • the ideal position for the sensor is centrally on a single-wheeled axle, such an arrangement being free from the inaccuracies described above, and that there should be no sensors on any twin- wheeled axle.
  • Figures 6 and 7 illustrate the use of the described monitoring system on an articulated lorry. Certain particular factors should be mentioned about this type of vehicle.
  • the front end of the trailer 4 is attached to the rear of the tractor unit 3 through a device which is known as the "fifth wheel" 5 which, as can be seen from figure 7, is located close to but forwardly of the rear drive wheels 9 of the tractor unit 3.
  • the trailer 4 normally has two or three pairs of rear twin-wheeled axles 49.
  • the sensors may be mounted elsewhere than on the front, single-wheeled axle, and in particular upon chassis components 50 directly over the rear drive wheels, as illustrated in Figure 7. If this alternative load sensing position is employed, it should be noted that two sensors will be required, one on each side in order to allow for lateral imbalance, for example where the lorry is laterally tilted.
  • the microprocessor can by subtraction calculate the axle weight of the rear drive axle.
  • a further inclinometer 57 mounted on the ram 56, and the output of this further inclinometer 57 is coupled to the microprocessor 20 of the monitoring system.
  • the microprocessor will be programmed on the assumption that the centre of gravity P of the load in the container 59 will be at a position which is substantially central longitudinally of the load container.
  • the load sensor is mounted on the front axle, and the microprocessor is operable, in the weighing mode of the system, to calculate the magnitude of the load acting at the assumed centre of gravity position which creates the measured effect at the front axle.
  • This load is added to the known unladen weight of the vehicle to produce the gross vehicle weight, and the front axle weight, known from the output of the sensor, is subtracted from the gross vehicle weight to produce the rear axle weight.

Abstract

Système de contrôle de la charge d'un véhicule routier, possédant une liaison de contrainte montée à un emplacement sur le véhicule choisi soigneusement pour donner une représentation précise et fiable de la charge appliquée. Cet emplacement se trouve également au centre et au-dessus d'un essieu à roues simples du véhicule. Un dispositif de calcul à microprocesseur traite le signal de sortie du capteur pour produire des signaux de sortie représentant des paramètres de la charge tels que les poids sur l'essieu, le poids brut du véhicule et la charge utile, et un affichage combiné avec une console de commande manuelle présente un affichage numérique pouvant afficher tous les paramètres de la charge selon une séquence prédéterminée. Le système possède un inclinomètre permettant la mesure de l'inclinaison du véhicule et compense cette inclinaison lors du mesurage. Le système peut également compenser les variations de niveau de carburant de manière à donner toujours des valeurs de lecture des paramètres de la charge correspondant à un mesurage effectué avec le réservoir plein. Ces caractéristiques sont combinées dans le mode de réalisation ci-décrit pour obtenir la précision nécessaire pour assurer le respect de prescriptions légales strictes sans sous-charger sensiblement le véhicule.
