Definitions

  • the present invention relates generally to the field of levelling systems for mobile objects, such as leisure vehicles, staging and portable toilets. More particularly, but not exclusively, the present invention concerns a levelling system for leisure vehicles, including caravans, trailers and motorhomes.
  • One solution is to have a fully-automated levelling system installed in the leisure vehicle, using either hydraulic or electrically-controlled jacks.
  • the jacks that are positioned either at four corners of a motorhome, and/or spaced over the wheel axle of a caravan or trailer, are automatically lowered by differing amounts until the floor platform is level.
  • the systems are complex and therefore, expensive and also contribute significant additional weight to the leisure vehicle.
  • Another solution is to use a ramp and a crude level detector, e.g. a spirit level, which is simple, but more difficult to use in practice.
  • This system entails the positioning of one or more ramps just in front of a wheel or wheels at the side of the leisure vehicle that is lowest. The leisure vehicle is then either manually driven (by its own engine or by a caravan mover), or towed up the ramp(s) until the level detector shows that the floor platform is level. This process can be laborious and challenging since it is necessary to be accurate with the driving and the level detector needs to be regularly checked.
  • Caravan movers are a drive system that make positioning of a caravan or trailer (without its own drive system or engine) on a campsite pitch more straightforward. They comprise two or four electric motors that drive rollers adapted to engage with the wheels of the leisure vehicle.
  • a control system of the caravan mover is generally attached to the chassis of the leisure vehicle and powered through a connection to the leisure battery. Remote control with the control system allows a user to drive the leisure vehicle onto a designated pitch whilst either on or off the leisure vehicle.
  • a drive system for a mobile object comprising a platform and one or more wheel(s), the drive system comprising at least one drive motor adapted to drive the one or more wheels, characterised in that the drive system comprises a levelling system comprising a level detector, the level detector comprising at least one sensor adapted to detect a level condition of the platform and a drive controller adapted to communicate with the sensor in order to receive condition information regarding the condition of the platform, the drive controller further being adapted to control the drive motor(s) in response to said condition information.
  • the levelling system can be used to control a drive system (a towing vehicle or other mover) to drive the mobile object up one or more ramps in response to the condition of the platform.
  • the system is not expensive or heavy and is simple and easy to use, without the laborious checking and driving routine.
  • the drive system and levelling system are fully integrated and can be used on a caravan or trailer without requiring a secondary towing vehicle or communication with an on-board vehicle engine.
  • 'mobile object' what is meant is any wheeled or rolling platform, which includes leisure vehicles such as motorhomes, caravans, trailers or entertainment modules such as staging, portable toilets, etc.
  • 'drive system' what is meant is any means by which the mobile object can be driven in at least forward and backward directions up and down said ramp, including an on-board motor or engine, the engine of a towing vehicle, or a caravan mover, or similar.
  • the drive system comprises one or more rollers driven by said drive motor(s) and adapted to engage with one or more of the wheels of the mobile object.
  • the drive system comprises a casing adapted to sit on or parallel with the platform.
  • the casing comprises a mounting component adapted to attach the level detector to said platform.
  • the mounting component is fixed to the casing.

  • the level detector is adapted to be mounted by said mounting component parallel with a wheel axle of the mobile object.
  • the drive system comprises a connection to a power source.
  • the drive system comprises a remote controller communicable with the control system to allow a user to drive the mobile object.
  • the remote controller may be a purpose-built remote unit, employing infrared or other communication technology with said drive system.
  • the remote controller may comprise a smart phone software application, employing wireless or Bluetooth® technology to communicate with the drive system.
  • the drive system comprises a first normal mode and a second levelling mode.

  • the level detector 20 is a retro-fit component that is firmly fixed to the platform 54 that is the chassis of the vehicle 50.
  • the level detector 20 comprises a mounting component (not shown) adapted to attach a casing 21 of the level detector 20 to said platform 54. It is, however, to be appreciated, that the level detector 20 should ideally, in a single axle mobile object like a caravan, be positioned parallel with a wheel axle of the mobile object.
  • the level detector 20 comprises a connection 58a to a leisure battery 58 in order to power the level detector 20. Since the leisure battery 58 is typically installed outside of an engine compartment of the motorhome 50, but close to a main battery 59 in order that a further connection 58b can be formed therewith, the level detector 20 is generally positioned as close to the front of a leisure 52 compartment as possible, or within the cabin 51 .

  • the set-up option further provides the selection of a ramp arrangement or plan, depending upon the position of each ramp 30 in use. This is achieved through a pictoral display of a variety of ramp arrangements on the display 29 at the outset. Accordingly, the drive controller 26 is adapted to be configured according to the geometry of the, or each ramp in use 30.
  • the drive controller 26 is adapted to calculate a drive range for each ramp 30 and select the shortest drive range as the maximum drive range.

  • the level detector 20 is 'set-up' by prompting user-selection of a ramp arrangement and ramp profiles on the display screen 29.
  • the drive controller 26 calculates the maximum drive range allowed during the levelling operation.
  • the information exchange connection 23a is formed between the level detector 20 and the engine management system 57 using standard Bluetooth® protocol.
  • the drive controller 26 sends a forward-drive command to the engine management system 57, which in turn drives the engine 56 to drive the wheels 55 up the ramps 30.
  • the drive controller 26 receives condition information from the sensor 24 at no less than one second intervals. Once a level condition has been received by the drive controller 26, the drive controller 26 immediately sends a brake instruction to the engine management system 57, thereby applying brakes to the wheels 55.
  • the drive controller 26 waits for another two condition information receipts to check the level condition of the platform 54. If the level condition is maintained, the drive controller 26 immediately sends a handbrake-on instruction to the engine management system 57 before the user can switch off the engine 56.

  • the levelling system 10 and drive system 1 1 0 respectively can be used to control an independent drive system 56 (an on-board engine, a towing vehicle), or integrated drive motors 156, respectively, to drive the mobile object 50, 150 up one or more ramps 30, 130 in response to the condition of the platform54, 154.
  • the system 10, 1 1 0 in either guise is not expensive or heavy (unlike the existing jack systems), and is simple and easy to use without the laborious checking and driving routine afforded by existing ramp kits.
