Description

ANCILLARY CONTROLLER FOR A VEHICLE TRAILER
This invention relates to an ancillary controller for a vehicle trailer, and in particular to a controller adapted to control certain components and systems on a vehicle trailer when the trailer is not hitched up to a road-going tractor unit.
Many vehicle trailers are known to have on-board systems and components which require power and control. The systems and components are normally powered and controlled by supply lines from the tractor unit, i.e. when the trailer is in normal use behind a road-going tractor unit, the tractor unit supplies power and control to the trailer systems and components by way of umbilical links.
The systems and components concerned can include anti-lock braking systems, proximity sensors, visible and audible reversing indicators, GPS tracking systems, trailer telemetry systems, and trailer height control systems,
for example.
The trailer is not always connected to a road-going tractor unit having the required umbilical lines, for example the trailer may be temporarily stored in a trailer or shunting yard. It may be that the trailer needs to be moved within the yard, and a tug or "dock spotter" can be provided for that purpose.
However, whilst the tug will have the required facilities to couple to the trailer so as to move the trailer, it will typically not have connections for umbilical lines to provide power and control to the trailer systems, so that the trailer is moved within the yard without those systems.
It is clearly desirable that at least some of the trailer systems are operable even if the trailer is not connected to a tractor unit having the required pneumatic and electrical umbilical lines. For example, it is desirable that the reversing indicators (and other reversing systems) operate when the trailer is moving backwards, even in a trailer yard. Also, the weather and ground conditions may make it desirable that the anti-lock braking system is operable. The present invention is directed towards a system controller allowing the use of some or all of the trailer systems when the usual source of power or control is not available from the towing vehicle.
According to the invention therefore, there is provided an independent ancillary controller for a vehicle trailer, comprising sensing means for detennining whether the trailer is umbilically connected to a tractor unit, control means connected to the sensing means for issuing control signals to a trailer system or component, and power supply means to provide power to the control means and to the trailer system or component.
Preferably, the sensing means is connected to both the air supply and electrical supply lines of the trailer, so that the ancillary controller can determine whether or not pressurised air and electrical control is being provided by a tractor unit. Desirably, the ancillary controller is inactive if pressurised air and electrical control is being provided by the tractor unit, and is active if pressurised air is being provided but electrical control is not.
Desirably also, the ancillary controller has a stand-by inactive mode if neither pressurised air nor electrical control is being provided, it being understood that the trailer cannot be moved, even in a trailer yard, without the connection to a supply of pressurised air to release the trailer brakes.
Preferably, the ancillary controller also has movement detection means to determine whether or not the trailer is moving, the movement detection means being connected to the control means. In this way, the ancillary controller can be made active only when the trailer is being moved. This will avoid the trailer systems and components being operated when, for example, the trailer is undergoing maintenance, for example maintenance of the braking system.
Desirably, the movement detection means can determine the direction and/or speed of travel of the trailer. Thus, certain of the trailer systems and components will only be required to operate when the trailer is travelling backwards, and perhaps above a threshold speed.
Preferably, the movement detection means comprises one or more of: a wheel sensor adapted to detect the rate of rotation of a road wheel; an accelerometer able to provide signals indicative of the direction and speed of movement; a tracking device, suitably a GPS tracking device. If the movement detection means includes or comprises an accelerometer, the control means can include a sub-routine to reset the system each time the pressurised air supply is disconnected, since the trailer may be parked on a hill and the accelerometer will not be able to differentiate between the trailer being parked on a hill and accelerating steadily on a flat surface. Alternatively, the movement detection means can comprise a set of orthogonally-arranged accelerometers able to detect and eliminate the effect of gravity.
Preferably, the power supply means comprises at least one battery.
Preferably also the power supply means can receive electrical power from the trailer electrical supply line when this is connected to the electrical supply of a tractor unit, so as to recharge the power supply means. In this way, the power supply means can be recharged each time the trailer is in use behind a road-going tractor unit. Alternatively or additionally, the power supply means can include a separate connector to allow its recharging.
Preferred embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings, in which: Fig. 1 is a representation of a vehicle trailer fitted with an ancillary control system according to the present invention; and Fig.2 is a block diagram of the ancillary control system.
The trailer 10 shown in Fig. I is of typical construction, having a set of road wheels 12 and a hitch point 14 by which it may be hitched to a tractor unit or tug (not shown). The trailer includes a number of comiectors 16 by which it may be connected to the tractor unit, a number of conventional flexible umbilical lines (not shown) being provided for this purpose.
In known fashion, the umbilical lines are colour coded and comprise: 1. The pneumatic supply line, often called the emergency line.
2. The pneumatic control line, often called the service line.
3. The 24N (normal) electrical supply line supplying power and control to basic lighting on the trailer.
4. The 24S (supplemental) electrical supply line which supplies power and control to certain trailer systems including for example reversing systems, fog lamps and ABS systems.
5. In addition, there may be a line providing dedicated power and warning lights for the ABS/EBS systems.
All of the umbilical lines must be connected if the trailer is to be used on the road and have all of its on-board systems operated. Only the pneumatic supply (emergency) line is needed to be connected to release the trailer brakes and allow the trailer to be moved.
The trailer 10 in this embodiment has air suspension and air brakes, and incorporates the following systems and components: (1) audible reversing warning 20, (2) ultrasonic proximity detectors 22 (3) height-adjustable suspension, (4) anti-lock brakes.
In relation to the audible reversing warning, it will be understood that the trailer has standard reversing lights 24 along with tail lights and brake lights, and the audible reversing warning comprises a loudspeaker 20 which is activated when the trailer is reversing to warn persons in the vicinity of the rear of the trailer 10.
In relation to the ultrasonic proximity detectors 22, these detectors are activated when the trailer is reversing and can detect the presence of an object close to the rear of the trailer. The detectors can trigger an audible and/or visible alarm, and can send a signal to apply the trailer brakes.
In relation to the height-adjustable suspension, the height of the trailer platform 26 can be adjusted, typically to match the height of a loading platform when the trailer is being loaded or unloaded, or to allow the height of the trailer to be adjusted (usually lowered) to avoid an obstruction such as a low gantry or the like.
All of these systems and components (and others) are already in use on vehicle trailers, and all are powered and controlled by the road-going tractor unit (not shown), and specifically by way of the umbilical lines from the tractor unit. Accordingly, when the tractor unit is not hitched to the trailer 10, or the umbilical lines are not connected, there is no power or control available for these systems and components.
When the trailer 10 is located in a trailer or shunting yard, therefore, the on- board trailer systems and components are not operable. However, it is often necessary to move a trailer around a trailer yard, and a tug or "dock spotter" is used for this purpose. The tug has a hitch point which can cooperate with the trailer's hitch point 14, and has means to connect a pneumatic umbilical line which is necessary to provide the pressurised air required to release the trailer brakes. (It will be understood that a tug may also have means to connect the pneumatic control line and the 24N (normal) electrical supply line, but these connections are typically not used in shunting operations).
In order for the on-board trailer systems and components to be operable when the trailer 10 is connected to a tug, according to the present invention the trailer 10 includes an ancillary controller 30. In the embodiment shown, for the purposes of clarity the controller 30 is located in a housing which is visible, but in most applications the controller 30 would not normally be visible.
The main components of a preferred embodiment of ancillary controller 30 are shown in Fig.2. The ancillary controller 30 has a control means 32 and sensing means 34a, 34b and 34c connected to the control means and respectively also connected to the trailer electrical supply line 36 and the trailer pneumatic supply lines 38 (one of the pneumatic supply lines providing emergency air pressure, the other providing service air pressure).
The pneumatic supply lines 38 are both connected to a relay emergency valve or EBS module 40, and subsequently supply pressurised air to lines (not shown) connected to the trailer's braldng system.
It will be understood that when the trailer 10 is hitched to a road-going tractor unit and the umbilical lines are connected so that the power and control for the trailer systems are provided by the tractor unit, the control means 32 is not required since the power and control for the trailer systems and components are provided by the tractor unit. In such circumstances the sensor 34a will detect the electrical supply through the trailer electrical supply line 36 and the sensors 34b and 34c will detect the air supply through the pneumatic supply lines 38. Since the trailer systems and components will receive power and control from the tractor unit the ancillary controller 30 is not required and the control means 32 is inactive.
Also, when the trailer is not connected to a tractor unit or to a tug, the electrical supply line 36 and the pneumatic supply lines 38 are disconnected from their respective umbilical lines. Since the trailer brakes will be applied and the trailer cannot be moved without the supply of pressurised air, the ancillary controller is not required in these circumstances and it can be inactive or in a stand-by mode.
Accordingly, the sensing means 34a, 34b and 34c communicate the status of the respective supply lines to the control means 32 which can determine whether the controller 30 should be active or inactive, i.e. whether or not it should provide power and control to the trailer on-board systems and components.
Thus, when the sensing means 34b detects that the emergency air supply has been connected to the trailer unit, and the sensing means 34a and 34c detect that the electrical supply line 36 of the trailer 10, and the service air supply, are not connected, that will indicate that the trailer may be moved, perhaps by a tug, and the control means 32 becomes active.
Wheel sensors 42 are also connected to the control means 32, the wheel sensors in this embodiment comprising sensors attached to a wheel at each side of the trailer 10. Accordingly, the sensors 42 can communicate movement of a wheel at each side of the trailer 10 to the control means 32.
Alternatively, one or more accelerometers can be connected to the control means 32, to allow the control means 32 to determine the acceleration /deceleration of the trailer, and therefore also the speed and direction of travel of the trailer 10. Accordingly, the control means can determine if the vehicle is travelling forwards or backwards, and at what speed, andlor is turning.
It will be understood that a trailer 10 fitted with anti-lock brakes will have wheel sensors for use in the anti-lock braking system, and the control means 32 can receive a signal from those sensors rather than requiring separate components. Alternatively or additionally, the trailer 10 may be fitted with a tracking unit, perhaps a GPS tracking unit, the tracking unit being fitted as part of the present ancillary controller or as part of an on-board system, the tracking system providing a signal to the control means to determine the direction and speed of travel.
It will be understood that to operate systems such as the reversing indicators or reversing proximity detectors, it is only necessary to know that the trailer is moving backwards. In the simplest embodiments of the invention therefore, the control means receives signals indicating only the direction of travel.
However, in preferred embodiments of the invention it is desired to know the speed and direction of travel, the speed being used to apply threshold values for the control unit. Thus, it is necessary from a health and safety aspect that certain on-board systems, for example automatic braking systems, are not activated unless certain conditions are met. For example, when the trailer is undergoing maintenance on its brakes, the emergency air supply line may be connected to allow the brakes to be released and it is essential that an automatic braking system not operate inadvertently if, for example, a person walks behind the stationary trailer.
If the trailer was fitted with a GPS or other tracking system then the ancillary controller could remain inactive until the trailer is moved. If, however, the ancillary controller responds to rotation of a trailer wheel then it is possible that the controller could be inadvertently activated during maintenance by a person spinning the wheel.
The control means 32 therefore preferably incorporates a lower threshold speed, for example 5 kmph, below which the control means will remain inactive. Preferably, however, once this threshold speed has been exceeded the system will remain active, even if the speed subsequently drops below 5 kmph, until some other control signal is received, for example the disconnection of the emergency air supply line.
Also, it is desirable that the control means becomes inactive if the vehicle travels above a certain speed, for example around 25 kmph, the upper threshold speed being chosen to be uattainable behind a tug or dock spotter, but attainable behind a road-going tractor unit, for example. Thus, it is desirable that the control means 32 be inactive if the trailer is connected to a road-going tractor unit and driven onto a public road with only the emergency air supply line connected.
The trailer 10 carries a battery or set of batteries 44 comprising the power supply means for the ancillary controller (in this embodiment the battery is shown separate from the control means 32 but in other embodiments could be incorporated therein). Usefully, the battery or batteries provide 1 2V or 24V, which are the voltages typically provided by tractor units. The control means 32 receives an input from the electrical supply line 36 which, when the sensing means 34a determines that the electrical supply line 36 is connected, can be communicated to the batteries 44 so as to recharge the batteries. In this way, the batteries 44 can be recharged from a road- going tractor unit when the ancillary controller is inactive.
When the ancillary controller 30 is active, the signals from the wheel sensors 42 (and/or the accelerometers or tracking unit in other embodiments) are used to determine the speed and direction of travel of the trailer 10. If it is determined that the trailer 10 is reversing (and a set threshold speed has been exceeded) then the control means 32 can activate the ultrasonic proximity detector(s) 22, the audible reversing warning loudspeaker 20 and the reversing lamp(s) 24. In systems having ultrasonic proximity detectors 22 such as the trailer 10 shown, the control means 32 can also be used to activate an alarm signal and/or the brakes in the event that an object is detected in the path of the reversing trailer, before the trailer strikes that object.
The trailer 10 in this embodiment is fitted with air suspension, and has facility for adjusting the height of the trailer platform 26. If it is desired to adjust the height of the trailer during movement around the trailer yard, for example when passing a low gantry, the control system 32 can issue the necessary control signal along control lines 50. Since height adjustment is not an automatic control, the control means 32 is connected to an input means 52 by which an operator may issue the necessary control instructions to the control means 32. It will be understood that the power to raise (or lower) the trailer height will be provided by the emergency air supply line 38, i.e. the ancillary controller 30 is required only to provide the control signals, and not to provide the (considerable) mechanical power required.
Certain trailer systems and components may only be required in certain conditions and can be selectively enabled or disabled by the control means when those conditions exist or do not exist respectively. For example, the system for raising and lowering the trailer height may be desired to operate only if the trailer is moving below a certain speed.
Also, the trailer 10 may be fitted with a speed limiting device designed to limit the speed of movement of the trailer (in both the forwards and backwards directions) to a predetermined low speed during shunting, so that the control means 32 can control the braking system and apply the brakes if that is necessary to maintain the trailer below the desired speed.
