Abstract

A portable control device interface for controlling or monitoring functions on a vehicle, comprises a graphical user interface with icons 101-106 which are displayed in first and second states dependant on a state of a function on the vehicle. In the first state, the icon has a first shadow in a first colour and when the icon is in the second state, the icon has a second shadow in a second colour. When the icon enters the second state a control signal is sent to a further device, in particular a trailer electronic braking system, adapted to present and receive control and/or monitoring information relating to functions on the vehicle. Icons 101-106 may be associated with traction assistance, lift axle lowering and maneuvering assistance for example. The invention allows a driver to see at a glance that a function is active.

Description

Display for a vehicle The invention relates to a display for a vehicle, in particular but not exclusively a display used in connection with a tractor trailer combination.
Electronic braking systems for commercial vehicle trailers and other related applications are becoming increasingly complex as additional fimctionality is introduced. It is also a highly competitive, cost conscious market. Trailers do not generally possess any autonomous power supply and rely for power on a tractor vehicle. The trailer is provided with an autonomous brake system having an independently operable trailer brake control unit. The trailer electronic brake control unit enables the trailer to be equipped with stability control and greatly enhances the safety Of the trailer.
There are many hundreds of small trailer builders in Europe and in other markets, due to customer demand for a high degree of customization on trailers. Different trailer operators will also want to have different auxiliary functions. In the context of a trailer, auxiliary functions is a term of art covering a variety of features relevant to the operation of the trailer such as Lift Axle Control, Reset to Ride and Integrated Speed Switch. The control algorithms for these functions can be held on a dedicated area of the brake control unit as is disclosed in GB2395241 or on a separate integrated circuit.
As many trailers are in effect bespoke, it is necessary to keep detailed and accurate configuration information for the trailer on the trailer as the trailer will be used with different tractors. Bar code solutions have been proposed but the barcodes are usually only be applied by means of an adhesive label, which may break or be covered with dirt during its use. To ease the maintenance and servicing of the brake systems, trailer brake manufacturers offer electronic data storage modules such as a trailer information module (TIM) or Info-Centre which is adapted to read and store operating and/or configuration data for the trailer on which it is installed and then to display the information on a screen for an operator. As such systems need to work when the trailer is without power and also need to operate in a wide range of conditions such as from -20 °C to +50 °C, as well as in exposed and dirty conditions, the systems have tended to be expensive in the context of a highly competitive trailer market and have not been widely, adopted in many markets.
The known systems suffer from an additional problem in that the onboard data generated by the sensors and brake control system can only be extracted using proprietary software and diagnostic hardware systems. The diagnostic equipment represents an additional overhead for the trailer builder and the software suffers from the problem that it is specific to a particular operating system. As operating systems are updated every two to three years and are often not fully back compatible, the software needs to be regularly updated. As the lifespan of a trailer has proven to be longer than the lifespan of major operating systems, this represents a significant commercial and technical problem to the widespread adoption of electronic data storage systems.
The applicant has proposed in the non prior published GB 1216544.5 to provide the braking electronic control unit of the trailer with the means to interface to the trailer electronics and a communications interface, so that inputs from sensors on the trailer and/or inputs from sensors received by the braking ECU can be rendered in standards compliant software and transmitted to a further device remote or distinct from the trailer, which further device is adapted to display information so received using a standards compliant client.
If such a device is to be used as a control or monitoring interface during vehicle use, it will need to be able to show to the driver that a function is active in all ambient conditions. The driver also needs to be able to see that the function is active with a single glance time of less than two seconds for safety reasons. It is not possible to use LEDs for this interface as the LED would need to be so large that any information underneath would be obliterated by the brightness of the LED or alternatively the interface would need to so large as to be impracticable.
The present invention therefore seeks to provide a control interface and device which meets these requirements.
According to the invention there is provided an interface for a device for controlling or monitoring functions on a vehicle, which interface comprises a graphical user interface having at least one icon, which icon has first and second states in dependence on a state of a function on the vehicle, wherein when the icon is in the first state, the icon has a first shadow in a first colour and when the icon is in the second state, the icon has a second shadow in a second colour, wherein when the icon enters the second state a control signal is sent to a further device adapted to present and receive control and/or monitoring information relating to functions on the vehicle.
Preferably, the second shadow is smaller than the first to thereby create an effect that the icon is depressed. Preferably, the icon is provided with a spot located within the boundary of the icon. Preferably, the colour of the spot is changed to show when a function is active.
An exemplary embodiment will now be described in greater detail with reference to the drawings in which: Fig. 1 shows schematically a trailer electronic braking system Fig. 2 shows a control interface Fig. 3 shows a control interface for a selected function.
Figure 1 shows schematically the arrangement of a trailer access microcontroller with a trailer electronic braking system. The trailer electronic braking system is only partially illustrated for reasons of clarity but includes a pressure control module 13 which is shown receiving wheel speed signals from wheel speed sensors 5,6. The pressure control module 13 also receives inputs from the lift axles showing the position of the lift axles and also the steering lock. The pressure control module 13 also receives power and data via an electrical connection from the tractor and is also attached to an ISO 11992 CAN databus.
A trailer access point (TAP) comprising microcontroller 60 with a CAN interface is also provided, which is powered from the electrical connection. The microcontroller itself comprises an interface to the on-board electronic systems and the trailer electronic braking system and an interface for sending and receiving data in a wireless format 61. The communications interface 61 can comprise one or more of a Wi-Fi router or Bluetooth card or radio transceiver. The trailer access point is connected to the CAN bus on the trailer and so is able to receive data from other devices on the CAN bus. The trailer access point can further be provided with USB ports, which enables the addition of peripheral devices on the trailer. An exemplary device on the CAN bus is the rear obstacle detector 62 and an exemplary device attached to the USB port is a reversing camera. USB is preferable in this case as the camera would generate large amounts of data compared to the remaining data on the CAN bus.
The trailer access point can be mounted in a housing similar to that used for a trailer information module but without a display being necessary. If a display is needed, it would be possible to use a bistable cholestatic display or zero power LCD display.
In use, when the trailer access point is powered, the provision of the webserver enables the data from the devices to be read by another device with a client browser.
Such devices could include a tractor navigation system or a smartphone.
Figure 2 shows an exemplary control interface for a control device with a touchscreen. The screen is provided with six icons showing various trailer functions that can be controlled from the device such as lift axle control, tyre pressure, auxiliary functions, a web cam, bogie load and tilt angle, respectively. The list of functions is not exhaustive but will depend on the trailer. The driver is able to use the control interface on the touchscreen to send commands to the Trailer Access Point, which can then send on control commands to the brake and chassis control of the trailer via the CAN bus.
Figure 3 shows a control interface for a selected function. The interface has a title bar showing the function being controlled, in this case Lift Axle Control. The interface is provided with six icons 101-106, one of which (106) is blank. The remaining five icons show exemplary functions for use in Lift Axle Control, namely: traction assistance (101), Lift Axle lowering (102,103,104) and manoeuvring assistance (105).
In a first state, when the function is not activated, the icon is provided with a first shadow, which is shown on the right and lower side of the icon in a dark grey colour creating a visual impression that the icon is a raised or floating button illuminated from above and to the left of the icon.
In a second state, when the function is activated, the shadow is changed to have a reduced size around the icon and a different colour, green, is used. Green is preferable as it is readily understood by a driver to mean that the function is in order and active. By reducing the size of the shadow around the icon, the impression is created that the button of the first state has been depressed. The icon itself remains the same size and in the same position.
The icon is also optionally provided with a small circle illuminated in the same colour of the second shadow. This provides an additional visual indication that the function is active.
