Abstract

A vehicle mounted height measurement system derives the height of a vehicle and cargo from a measurement of the combined distance from the highest point 24 of the vehicle 12 and cargo 40 to the road surface 26. The system comprises a vehicle-mounted unit comprising an extending mast 28; a sensor 30 measuring a vertical distance; a sensor 32 detecting cargo in a horizontal plane; a system control unit 34. The system control unit 34 may communicate with a smartphone app or software built into a vehicle’s 10 management system, which may direct to measure the vehicle height before every journey and instruct a measurement procedure. Software may determine that measurement is above the maximum allowable operating height. Through the smartphone app or the vehicle 10 management system software the system control unit 34 may communicate via the internet or cellular network with a cargo management or fleet management operation, insurance company or government enforcement agency. Sensors 30, 32 may be acoustic, optical or electromagnetic sensors / transducers.

Description

Vehicle Height Monitor This invention relates to the height measurement of vehicles that carry a cargo at variable heights-for example, car transporters, cranes, and skip carriers.
Background
The problem exists whereby vehicles that carry variable height cargo are colliding with bridges that traverse the highway. As well as damage to the vehicle and its cargo the act of striking a bridge can cause it to suffer structural instability and may render it unsafe. In many cases, these bridges are for the conveyance of other transport. As a result, bridge strike can cause significant disruption, costly repairs and the potential for loss of life and cargo.
Highway bridges have generally been constructed to provide a minimum standard clearance (or greater) from the road surface. Older structures may not provide that minimum clearance and in such cases are typically marked with the clearance height, to enable a driver of a vehicle to know in advance whether his vehicle can pass safely under the bridge, or that he must find an alternative route. To this end, drivers need to know the height of the highest point of the vehicle from the road.
There are many vehicles whose overall height varies quite significantly due to differing loads, hydraulic platforms (in the case of car transporters), and adjustment of an air suspension system. For such vehicles, the driver obtains the overall height of the vehicle on commencement of duty. The height is recorded on an in-cab display as appropriate.
Vehicle height sticks are readily available. They comprise a folding stick with a sliding projection at ninety-degrees at the top. The projection is set using a scale at the desired operating height. It is then held up against the side of the vehicle and cargo by the user. Such a gauge is best used when a vehicle is operating with air suspension operating and on level ground. Loads can often be uneven, and it is difficult for the user to see any interference between the height stick and cargo from ground level. Most often only a small part of the cargo can be seen from the ground.
There is no available provision; however, whereby combined vehicle and cargo height measurement can be carried out easily and objectively, that would be available to vehicle owners for immediate, accurate measurement and to law enforcement agencies for road safety purposes. There is, moreover, no system available for automatic vehicle and cargo height monitoring as an 'on-vehicle' System.
Summary
The present invention provides such a vehicle and cargo height measuring system.
The invention comprises a vehicle and cargo height measurement system in which the combined height of the vehicle and cargo is derived from a time-of-flight calculation of an electrically triggered signal sent from the highest point of the vehicle and cargo to the road.
The invention may comprise a mechanically elevated platform; vertical sensor; horizontal sensor; system control unit. The benefit being that the elevating platform, while attached to the vehicle, is able to extend to the sensors in line with highest point of the cargo.
The mechanically elevated platform may comprise a motor that extends a telescoping mast beyond the highest level of the vehicle and cargo. The benefit being that the platform can be elevated automatically by the control system.
The vertical sensor may comprise a transducer to determine the distance between the transducer and the road surface.
The horizontal sensor may comprise transducer to determine the distance to any obstructions (i.e. cargo) on the horizontal plane.
The horizontal and vertical sensors may be located at the top of the mechanically elevating platform.
As the telescoping mast extends the horizontal sensor may receive no reflections from the vehicle and cargo at the point at which there is no interference from the vehicle and cargo on the horizontal plane.
The vertical sensor may receive reflections from the ground when the horizontal sensor receives no reflections from the vehicle and cargo.
The system control unit may be contained in a vehicle-mounted enclosure and may communicate with a smartphone app, or software built into a vehicle's management system, which may give directions for vehicle and cargo height measurement and step a user through a measurement procedure.
The system control unit may be powered by a feed from the vehicle's electrical system or by its own on-board battery. The system control unit provides power to the mechanically elevated platform, and vertical and horizontal sensors.
Decoding means associated with the system control unit for converting a received horizontal or vertical sensor measurement into signals which will cause a distance corresponding to the height of the highest point of the vehicle from the ground to be calculated numerically in standard units of length such as metres and centimetres, or feet and inches.
The vertical or horizontal sensor transducers may perform a dual function, firstly as a distance signal transmitter transmitting pulses of energy towards the ground or cargo and secondly as a receiver which receives reflected energy from the ground, the phase or time difference between transmission and receipt of the reflected energy being decodable in known manner into distance between the transducer and the ground or cargo, for determining the signal to be transmitted to the system control unit.
The transducer may be one which operates at ultrasonic frequencies, or infra-red or visible light wavelengths, or in the microwave part of the radio frequency spectrum typically used by radar.
Through the smartphone app, or the management system software and on-board communication system, the signal may communicate via the internet or a cellular network with a cargo management or fleet management operation, an insurance company or a cargo monitoring operation e.g. of a government agency.
Brief Description of Drawings
Vehicle and cargo height measurement systems according to the invention are described below with reference to the accompanying drawings, in which: Figure 1 is a side-on view of a vehicle and cargo with a vehicle height monitor; Figure 2 is an enlarged view of part of Figure 1 with the mechanically elevated platform extended; and Figure 3 is an enlarged view of part of Figure 1 with the mechanically elevated platform un-extended.
Detailed Description
The drawings illustrate an example of the vehicle height monitor in which combined vehicle and cargo height h is derived from a time-of-flight measurement of an ultrasonic signal sent 20 from the vertical sensor 30 to the road surface 26 and reflected back to the vertical sensor 30.
The time difference between transmission 20 and reception 22 of ultrasonic signals is calculated. Using the speed of sound and 'Speed = Distance/Time' equation, the distance (in this case h) between the source 30 and target 26 can be easily calculated. Time taken by the pulse is for the complete trip from the sensor 30 to the road surface 26 and back to the sensor 20. Only half this time is required to measure h from the sensor 30 to the road surface 26. Therefore, time is taken as time/2.
Distance = Speed *Time/2 Speed of sound at sea level = 343 m/s Thus, Distance = 1715 * Time (unit m) The system is suitable for all road surfaces. The road surface should be level, however, should it be soft e.g. loose dirt, or snow and extend above the point at which the vehicle 10 meets the road 26 the measurement will be shorter therefore still meeting the requirement of keeping the total height below the desired measurement.
The vehicle height monitor comprises a vehicle-mounted unit 34 comprising a mechanically elevated platform 28; distance sensor 30 that measures a vertical plane; sensor 32 that detects objects on a 360-degree horizontal plane 24; system control unit 34.
The vertical sensor is mounted on the underside of the mechanically elevated platform at the furthest point away from the vehicle so that it has an unobstructed line-of-sight to the road surface.
The vertical 30 and horizontal 32 sensors are mounted on a mechanically elevated platform 28. The platform extends while the horizontal sensor detects objects 360 degrees on the horizontal plane 24. When the horizontal sensor detects no objects 36 from the vehicle 10 & 12 and cargo 40 the vertical sensor 30 measures the distance to the ground 26.
The system control unit 34 comprises a vehicle-mounted enclosure and communicates with a smartphone app or software built into a vehicle's management system, which may give directions for vehicle and cargo height measurement and step a user through a measurement procedure. This procedure generates a measurement h from the highest point of the combined vehicle 10 & 12 and cargo 40 to the road surface 26. Software will either determine that the measurement h is above or below the maximum desired distance h from the road 26 to the highest point of the vehicle 10 and cargo 40. The desired height may be different for each application but will correspond to the lowest height of any perceived obstacles e.g. motorway over-bridges, railway bridges, known low trees etc. The comparison of the h value and the maximum desired height may produce a go-no-go test. Go if the h value is less than the desired height and no-go if the h value is greater than the desired height. Distance h may also be used for analysis, for example, by a cargo monitor function that facilitates cargo management or predicts fuel consumption.
Through the smartphone app, or the management system software and on-board communication system, the measurement h may be communicated via the internet or a cellular network with a cargo management or fleet management operation, an insurance company or a height monitoring operation e.g. of a government enforcement agency.
