Definitions

  • the present invention relates to vehicles, and particularly but not exclusively to airside support vehicles.
  • the invention also relates to a retro-fit apparatus for converting a vehicle, method of charging a vehicle, airside support systems, and computer- implemented methods of reducing maintenance required on battery powered airside support function equipment that is used intermittently.
  • the invention is also especially applicable to warehousing vehicles or dockside vehicles for logistical supply of items in warehouses.
  • the present invention also relates to methods of providing electrical power to a battery powered self-propelled vehicle in an operating environment, reducing inefficiencies in a logistical system comprising a plurality of vehicles, and increasing the useful operational time of electrical airside support vehicles on an airfield.
  • the invention also relates to energy storage vehicles and logistic systems, and particularly, but not exclusively, vehicles and logistic systems for use in airside environments.
  • the present invention also relates to methods of controlling or monitoring remote controlled vehicles, particularly but not exclusively to computer-implemented methods of controlling or monitoring remote controlled vehicles, and particularly but not exclusively to computer-implemented methods of controlling airside support vehicles.
  • the invention also relates to control vehicles for controlling remote controlled vehicles, retro-fit apparatuses for converting a vehicle into a remote controlled vehicle, remote controlled vehicles, and transportation and/or logistics systems, particularly but not exclusively airside transportation and/or logistics systems.
  • Airside operations and other logistical environments such as warehouse or docksides, often utilise many vehicles for transporting cargo, baggage and sometimes people.
  • the vehicles will often be operational for long shifts and will be in constant use or intermittent use.
  • the vehicles are therefore usually internal combustion engine driven, as refuelling take seconds or at most minutes compared to the hours that are usually required for battery powered vehicles to recharge.
  • battery vehicles are used they are normally only operational over shorter shifts, or are required to be substituted by further vehicles whilst charging.
  • underground inductive charging may be used. This requires a considerable investment and the installation of new infrastructure. Such an upheaval would mean significant loss of time and money for somewhere like an airport, with runways and parts of the airport apron, and airside environments unable to be used for weeks and perhaps months.
  • Airside environments such as in airports, and other logistically intensive environments require a lot of personnel to be run effectively. Whilst human control is good for some tasks there is an inherent risk of human error in any human controlled system. It is therefore desirable to increase efficiency of operations. Efficiency can be measured in terms of minimising downtime such as wait-times, maximising speed of delivery and embarkation and disembarkation of passengers, maximising utilisation of available space and vehicles, and minimising energy usage. Another aspect of efficiency can be reducing accidents. Airside vehicles under human control do sometimes strike aircraft, causing costly delays to flights, and costly repairs being needed for aircraft. It is common for aircraft operators to have a spare aircraft or two at an airport in case a scheduled aircraft is damaged and cannot fly. This is expensive.
  • known airside logistics systems include a number of drawbacks, many of which impact upon efficiency. Similar drawbacks are also applicable to other logistics systems, of which airside logistics systems may be considered a subset. For example, storing and retrieving goods in warehouses or at a shipyard or railway or road freight distribution centre are other areas where the present invention also can be used.
  • a vehicle is self- propelled and configured to be operable without a driver present in the vehicle.
  • the vehicle comprises a charging apparatus and a traction motor.
  • the charging apparatus is configured to receive a charge from an external point.
  • the vehicle is configured to receive the charge whilst the vehicle is in motion, and/or or whilst it is carrying out its airside support function.
  • a vehicle configured to be self-propelled and configured to be operable without a driver present in the vehicle.
  • the vehicle comprises a charge receiving apparatus configured to receive a charge from an external point, a charge delivering apparatus configured to deliver a charge from an external point and a traction motor.
  • the vehicle is configured to receive or deliver the charge whilst the vehicle is in motion, and/or or whilst it is carrying out its airside support function.
  • the vehicle may be an airside support vehicle.
  • the vehicle may be operable in an autonomous mode or be fully autonomous.
  • the vehicle may be remotely controllable.
  • the remote control of the vehicle may be undertaken by a human or an on board or off board computer.
  • the traction motor may be a bodily translation electric motor adapted to move the vehicle between different places airside.
  • the vehicle may further comprise an effector motor.
  • the effector motor may be adapted to move a component on the vehicle to perform a non- vehicle moving action, such as moving a component of the vehicle not associated with translocating the vehicle.
  • the vehicle may be adapted to receive a charge whilst either or both of the effector motor and bodily translation motor are operating.
  • the charging apparatus may be an inductive charging apparatus.
  • the charging apparatus may be positioned at a fore and/or an aft position on the vehicle.
  • the charging apparatus may be arranged to have an induction coupling plate extending generally vertically. Vertically orientated plates are less likely to catch water when it rains on them, and are less susceptible to people stepping on them and damaging them or putting things on them as if they were a shelf, and are less likely to collect debris that will interfere with energy transfer.
  • the charging apparatus may instead (or additionally) be arranged to have an induction coupling plate extending generally longitudinally.
  • the generally vertically extending coupling plate may be configured to pass charge in a generally longitudinal direction with another vertically extending coupling plate on another vehicle.
  • the generally horizontally extending coupling plate may be configured to pass charge in a generally vertical direction with another horizontally extending coupling plate on another vehicle.
  • the generally longitudinally extending coupling plate may be configured to pass charge in a generally latitudinal direction with another longitudinal extending coupling plate on another vehicle.
  • the charging apparatus may comprise a plurality of charging regions on the vehicle.
  • the plurality of charging regions may comprise a first charging region positioned on a front of the vehicle and a second charging region positioned on a back of the vehicle.

  • the vehicle may be configured to be arranged into a platoon of vehicles and an electrical connection made between vehicles in the platoon such that the vehicles can share charge between them.
  • the plurality of charging regions may comprise charging regions positioned on a side of the vehicle. Positioning a charging region on sides of the vehicle can allow vehicle to share power whilst operating or moving side by side rather than following one another.

  • the vehicle may further comprise an energy storage means.

  • the vehicle may not comprise an energy storage means. Whilst the vehicle may have smaller energy storage means or otherwise less ‘heavy duty’ energy storage means, it may not have an energy storage means for storing energy for tractive purposes.

Not having energy storage means, or a smaller, lighter, energy storage means can enable the vehicle to be made more simply and much more cheaply, with fewer maintenance requirements. The vehicle may only be required to move at limited times.

Plotting the path comprises using the information provided by the sensing system 120 of each of the dollies to determine relevant distances in the operating environment. The plotted path can then be converted into commands which are sent from one or both of the dollies 100 to the RC vehicle 200, to be executed by its controller. The RC vehicle 200 can therefore be autonomously manoeuvred into position at the aircraft doors.

  • the RC vehicle 200 can be piloted between the dollies 100 as the sensor coverage afforded by the dolly positions allows a path to be planned and vehicle motion to be controlled within that.
  • the field of view offered by using multiple dollies 100 is much greater than a human operator can conventionally access. This allows for the elimination of blind spots and providing viewing angles not afforded to a human operator. Even where spotters may be used, the communication and control between the dollies 100 and the remote control vehicle 200 is much faster than human communication, as are responses to commands. The increase in operator safety over known systems and methods is therefore increased, as there is a reduced chance of collisions or other accidents.
