Definitions

  • the present invention relates to improvements in or relating to lighting boards for trailers, towed automobiles or load carriers, such as bicycle carriers, mounted to the rear of a vehicle, in which the signals between the vehicle and the lighting board are transmitted by radio waves.
  • Prior art lighting boards include multi- functional light units on either side of the board, typically with an additional number plate in between.
  • the lighting board is mounted visible to the driver of a following car and a wiring connection or a wireless connection is provided between the lighting board and the vehicle so that operation of the light units of the lighting board is syn chronised with operation of the rear lights of the vehicle in order to indicate a warning of any intended turn or of braking to the driver of a following car.
  • Wireless lighting board systems are operated by a radio transmission from a transceiv- er that is electrically connected to the electrical trailer plug system at the rear of the vehicle. Examples are disclosed in GB2375901 and US6100801 for trailers and in US5666103 for towed automobiles.
  • the wireless communication between the vehicle transmitter and the receiver in the lighting board is a practical and useful approach avoiding cabling between the vehicle and the trailer, it implies a risk that the radio frequency is disturbed and the properly functioning of the lighting board is not any longer guaranteed.
  • it is an objective to provide a more reliability functioning of a wireless rear light system especially for a trailer, a towed automobile or a load carrier on the back of the vehicle.
  • This objective is achieved with a wireless rear light system, for exam ple a lighting board, and its method of operation by radio communication, where commend signals are sent at two different radio frequencies in order to provide addi- tional safety through redundancy.
  • the system is explained in more detail in the fol- lowing.
  • the wireless rear light system comprises
  • radio transmitter unit configured for electrical connection to the electrical system of a vehicle; the radio transmitter unit being configured for receiving wired electrical power signals from the vehicle through the electrical connection, each of the power signals relating to either rear light, stop light or turning indicator light; wherein the radio transmitter unit is configured for providing and transmitting different specific wireless command signals relating to either rear light, stop light or turning indicator light in dependence on the wired electrical power signals received from the electrical system of the vehicle;
  • a light indicator system separate from the radio transmitter and comprising lamps for rear light, stop-light and turning light and configured for removable mounting on a trailer or towed automobile, for example a lighting board with a set of such lamps at either end of the lighting board; typically, this lighting system is mounted on a trailer, a towed automobile or a load carrying structure on the back of a vehicle;
  • a radio receiver unit comprising a radio receiver configured for receiving the com mand signals and a controller electronically connected to the radio receiver and con figured for connecting electrical power selectively to the lamps of the light indicator system in dependence of the received command signals;
  • the radio transmitter unit is configured for sending and the radio receiver for receiving the specific wireless command signals at two different radio frequencies for each wired electrical power signal received from the vehicle through the multi-pin plug.
  • frequency of the command signal refers to the carrier frequency of the com mand signals.
  • the specific signal itself would result as a modulation of the carrier frequency.
  • the dual frequency system is made with a transceiver and antenna for each frequency.
  • the dual signals for the activation of the lamps are sent by the transmitter at a first frequency, for example in the range of 800-900 MHz, optionally at 869.70 MHz, and also at a second frequency, for example in the range of 400-500 MHz, optionally at 434.05 MHz.
  • a first frequency for example in the range of 800-900 MHz, optionally at 869.70 MHz

  • the lower of the two fre quencies is far from the higher frequency, for example more than 10% different than the higher frequency, such as at least 20, 30, 40 or 50 % different than the higher fre quency, the risk for disturbance of both radio signals at the same time is reduced as compared to a signal at a single frequency. Accordingly, the system provides redun dancy with increased safety in a simple way and ensures reliable communication.
  • the dual command signals with different radio frequencies are sent sim ultaneously or approximately at the same time, for example with less than 0.1 seconds between the two signals.
  • the two signals have to be sent before the next wired power signal is received by the transmitter unit from the vehicle through the multi-pin plug.
  • the signals are digital.
  • An optional data rate for the radio signals is in the range of 10-100 kb/s, for example 40 kb/sec.
  • each electrical signal causes two radio signals being transmitted, where the dual signals have different frequencies.
  • the radio signals have a digital sequence of a destination address and a source address as well as a command sequence.
  • the desti- nation address and the source address in the radio signals prevents reading of the radio signals by a receiver that is not addressed and prevents the receiver from reading sig- nals from a transmitter of a neighbouring vehicle.
  • Received data packages in the radio signals with addresses that are not matching are disregarded and no commands exe- cuted by the controller. Only the specifically addressed receiver would evaluate the signal and cause the lighting in accordance with the intention of the user in the vehicle and synchronous with the vehicle’s rear lighting system.
