Definitions

  • This invention relates to a device intended to facilitate improved road safety by influencing driver behaviour, in particular by encouraging drivers to obey prescribed limitations on vehicle movement, for example speed limits.
  • the invention accordingly provides apparatus for mounting in a motor vehicle comprising: sensor means for monitoring indications, disposed externally of the vehicle, of a prescribed limitation on vehicle movement, and outputing a first signal representative of such an indication; information storage means; and comparison means adapted to be coupled to the sensor means to receive said first signal, to compare the prescribed limitation on vehicle movement with observed movement of the vehicle, and to store in said information storage means a record of a predetermined variation from said prescribed limitation.
  • the sensor means may be adapted to read indications comprising coded data, e.g. barcodes, on the road surface, or to respond to radio transmitters at the roadside which include encoded indications of the prescribed limitation.
  • the prescribed limitation might comprise a speed limit.
  • the externally disposed indications may then be located where there is a change in speed limit, so that a driver may be advised of a change of speed zone and adjust his speed accordingly, or might only be provided at the commencement or conclusion of zones in which the speed limit is other than a prescribed built-up area limit or a prescribed absolute maximum, for example 60kph or lOOkph respectively.
  • the comparison means may be coupled to receive signals representative of the actual speed of the vehicle. Such coupling may be mechanical, driven directly from a transmission or axle line, or might be electronic, being responsive to periodic pulses triggered by rotation of a transmission element such as the gear box, an axle member or a wheel.
  • the invention also embraces the aforesaid apparatus mounted in a motor vehicle.
  • the record of the predetermined variation i.e. the infringement record
  • the record might be provided in some form of sealed non-erasable format, for example in a memory chip. It is envisaged that when the owner of a motor vehicle is due to renew his motor vehicle registration or perhaps his driving licence, the _vehicle would have to be presented for official reading of the record and appropriate fines paid if renewal was to be effected.
  • the apparatus may further include timer means for determining the duration of a current variation from said prescribed limitation, and the predetermined variation may be a variation for at least a prescribed minimum time.
  • time such time, during which e.g. excessive speed would not be recorded, might be in the range 20 sees to 5 minutes, preferably about 30 sees. This would allow the driver freedom to, e.g. pass other vehicles or cope with emergency situations without fear of penalty, and would also prevent undue harshness.
  • the time should not be so great as to readily, and without inconvenience or close concentration, allow a driver to periodically briefly lower his speed to avoid penalty.
  • the invention also embraces the aforesaid apparatus mounted in a motor vehicle and is directed to a road surface having a marking which includes a machine readable encoded indication of a prescribed limitation on vehicle movement at or adjacent the location of the marking.
  • Figure 1 is a schematic diagram of the principal components of speed infringement recordal apparatus for a motor vehicle, being apparatus in accordance with a preferred embodiment of the invention
  • Figure 2 is a vertical sectional view of the shielded sensor means of the apparatus of Figure 1;
  • FIG 3 is a perspective diagrammatic view of a roadway fitted with a barcode speed indicator in ' accordance with another aspect of the invention
  • Figure 4 is a flow diagram of the interrupt program routine of the microprocessor for reading a barcode speed indication
  • Figure 5 is a flow diagram of the main program routine of the microprocessor.
  • the apparatus as schematically shown in Figure 1 includes a controller 10 and a reflex photoelectric sensor 12.
  • Controller 10 is mounted at any suitable location in the vehicle and is coupled both to receive electrical signals fron sensor 12 via a serial port 15 and to monitor the electronic pulse signals generated by a transmission element of the motor car, in this case a rear wheel 14, so as to be directly indicative of the speed of the vehicle.
  • Such pulses are typically delivered by a conductor 16 to the speedometer 18.
  • a branch conductor 20 delivers a proportional such speed indicative signal to controller 10' via an interface circuit 21.
  • Sensor 12 is provided to monitor external indications of a predetermined speed limit for the time being, viz the speed limit currently applicable on the stretch of road along which the vehicle is travelling. To this end, the sensor would typically be mounted towards the front underside of the vehicle, for example under the engine cooling fan and/or adjacent the radiator, but may be mounted at any other convenient location, e.g. adjacent the passenger cabin floor.
  • a suitable sensor arrangemen.t is illustrated in Figure 2.
  • the sensor 12 which is conveniently an infrared device and typically has a light transmission port 12a and an adjacent reflected light receiver port 12b, is supported within a tubular shield 22.
  • Shield 22 is obliquely truncated at its lower end so as to depend further at the front 22a, which respect to the vehicle's direction of travel, and thus to maximize diversion of mud and the like away from the sensor.
  • a venturi device, a convection fan or like means 24 is provided at the top of the shield for directing a flow of air 25 downwardly past and about sensor 12: mud or grime which is thrown up into the shield 22 is forced away by this air flow.
  • tubular shield 22 is in two axial parts threadingly coupled at 26 just below the sensor to facilitate regular cleaning of the sensor's light ports 12a, 12b.
  • the light ports might be cleaned by a physical element such as a mylar belt moved regularly or continuously across their external surfaces.
  • sensor 12 is responsive to
  • ⁇ barcodes on the road surface which include encoded indications of the local speed limits and of the location.
  • the envisaged barcode arrangement 40 is depicted in Figure 3.
  • a sequence of sharply contrasting lines or spaces 42 is applied to the road surface, the lines are straight and extend across the full width of the bitumen.
  • a barcode would typically include four encoded sequences. In the order in which they are encountered by the travelling vehicle these would include a characteristic opening sequence, a second sequence characteristic of the location of the speed zone, a third sequence indicative of the speed limit in the zone, and a fourth characteristic closing sequence.
  • respective suitable barriers such as so-called armco rails 46 are typically installed to either side of the barcode marking 40.
  • Controller 10 is of standard physical construction, comprising a microprocessor CPU 10', suitable information storage means in the form of memory modules 11, 13 in RAM and ROM, the former including a clock and calendar, a backup battery 50 for the data memory 11, serial port 15 to receive the signals from sensor 12, input interface 21 to speedometer line 16, and an output interface 17 with protection circuits 17a and external connector 19 by which the contents of specific memory addresses may be automatically read by a regulatory authority. Controller 10 also has outputs to an audible and visual warning display 28 and to a LED display 30. These elements would typically be sited for driver observation on or adjacent the vehicle's dash board. Power for the CPU and sensor 12 would be derived from the vehicle battery and be enabled by the ignition system. Backup battery 50 is provided to maintain the infringement record when other power fails.
  • controller 10 and its sequence of functions is determined by a program routine in a segment of ROM memory module 13. .
  • the principal functions are as follows:
  • warning device 28 when the speed is in excess of the speed limit, perhaps absolutely or more probably when in excess by a small margin, e.g. 2 or 3kph.
  • the prescribed limitation comprising the currently recorded speed limit.
  • the record of infringement typically include an encoded recordal of the speed limit, the location of the speed zone (as determined by sensor 12 from barcode 40) , the speed of the vehicle at the conclusion of the delay time, and the date and time of the infringement.
  • Controller 10 may include a facility to make a special memory record in EPROM if it or any part of it is disconnected or if the sensor 12 is obscured and unable to make a reading. Obscuring or ineffectiveness of the sensor might be notified to the driver at the
  • the apparatus further may include a vibration switch 52 adapted to output a signal, stored as a
  • This facility is intended to detect vehicle movement when, e.g., input interface 21 has been disabled or the apparatus has been otherwise rendered inoperative.
  • controller 10 is arranged to record particulars of any erasure or attempted erasure of the infringement record in memory module 11. When the owner of the motor vehicle comes to renew his motor vehicle registration, the vehicle would have
  • FIG. 30 is a flow diagram of the interrupt program routine by which a barcode indication of speed limit is read and entered, once detected by a signal from sensor 12. This routine is entered by interrupt vector when sensor receiver port 12b is enabled and the first bit is received by serial port 15. The routine thus includes the first two of the principal functions listed above.
  • Figure 5 is a flow diagram of the ' main program routine, embodying the other principal functions.
  • the "FLASH ON" instruction refers to flashing the visual component of display 28.
  • Speed limit ' s could be raised where appropriate without the fear that drivers will simply-take advantage and still travel at similar margins above the new limits.
  • the invention does not constitute any kind of speed governor and therefore in no way impedes the performance of the motor vehicle.
  • the driver can still exceed the speed limit briefly, for example when passing or to avoid a dangerous situation, and this provision of both a grace period and a warning to the driver renders the device "user friendly".
  • the driver is still able to travel very fast when required in an emergency. Proof of such an emergency would allow avoidance of a fine when the infringment record is read.
  • the invention is not limited in application to speed limits but may be applied to any prescribed limitations on vehicle movement, e.g. a red traffic light, a requirement to fully halt at a stop sign, specific movements set by arrows on the road surface, double lines, one way streets, and various no turn rules.
  • the program may also provide for special, e.g. lower, limits applicable to a vehicle of the particular type in which it is installed.
  • the inboard equipment may include additional facilities. For example, it may be programmed to record toll, parking or other charges of subsequent processing and payment: these may be indicated in external indications, such as barcodes in the road surface, and recorded via the sensor.
