Abstract
A level indicator device is disclosed for use in conjunction with a road vehicle such as a caravan, trailer, motor home or mobile crane and which comprises an electrically energized level sensor that is arranged to provide an output signal that is representative of a prevailing level of the sensor, a signal generator associated with the sensor and arranged in use to generate a signal that is representative of a substantially horizontal level when that level is sensed to prevail by the sensor. A radiofrequency signal transmitter is located in circuit with the signal generator and is arranged to transmit a radiofrequency signal that is modulated by the signal generated by the signal generator, and a remote receiver is provide and is arranged to receive and demodulate the radiofrequency signal. In one embodiment of the level indicator device the level sensor comprises a MEMS accelerometer that measures G-force in plural axes. Also disclosed is a vehicle level adjusting system for a road vehicle and which comprises a level indicator device as defined and a plurality of level adjusting devices, in the form of ramps or jacking actuators, that are arranged to effect levelling of the vehicle.

- G05D 3/00 - Control of position or direction
- G01C 9/00 - Measuring inclination, e.g. by clinometers, by levels
- B62D 33/063 - Drivers' cabs movable from one position into at least one other position, e.g. tiltable, pivotable about a vertical axis, displaceable from one side of the vehicle to the other
- G08B 1/00 - Systems for signalling characterised solely by the form of transmission of the signal
