  • Commercial vehicle manufacturers increased engine
    sizes to enable operators to move heavier loads
  • Problem When vehicle was not fully loaded, high
    speeds could be reached
  • Solution The development of road speed controls,
    in co-operation with vehicle manufacturers
  • Most development happened in Europe, led by the
    UK, from 1979 onwards

4
  • In 1984, the British Standards Institute decided
    to develop a Standard for road speed controls
  • This was completed by 1987, resulting in BSAU217
  • In 1989, the UK implemented legislation requiring
    speed controls to be fitted on buses and coaches
  • Europe developed its standard based on BSAU217

5
  • From 1995-7, EU legislation was passed for road
    speed controls to be fitted to all vehicles over
    12 tonnes throughout Europe
  • Numerous other countries adopted the EU and BS
    standards as they are internationally recognised
    by all vehicle manufacturers
  • Now, in 2006-8, EU legislation requires road
    speed controls to be fitted on vehicles down to
    3.5 tonnes gross design weight

6
In the decade after UK legislation was
introduced, deaths on British roads plummeted by
one-third from almost 5500 in 1989 to under 3750
in 1996

DbW System
System 80
System 90
System 2000
11
DbW System is for all vehicles with an electronic
pedal (accelerator), having neither a rod nor
cable throttle. The Electronic Control Unit (ECU)
operates with the vehicles Engine Management
System to control the set speed.
System 80 is an electronically controlled fuel
flow valve offering speed control in all climatic
conditions for petrol and diesel vehicles.
12
System 80Road Speed Controls
  • The System 80 range of Road Speed Controls are
    controlled by an Electronic Control Unit (ECU),
    which is connected to the Speedometer, or a
    mechanical gearbox sensor, to provide a frequency
    signal (speed related).

13
System 80 and DbWRoad Speed Controls
  • At a pre-set frequency, for example 80km/h
    (50mph), the ECU transmits a signal to the fuel
    flow valve. The valve closes, reducing the fuel
    to the carburettor/injectors, which reduces the
    vehicles speed.

14
System 80 and DbWRoad Speed Controls
  • The Diesel System has an adjustable by-pass built
    into the valve, which at the limited speed
    controls the amount of fuel to the injector pump,
    thus limiting the speed.
  • The Petrol System operates by controlling the
    fuel supply to the carburettor/injectors which
    reduces the power available to the engine, thus
    controlling the speed. This system includes a
    speed indicator unit, incorporating a warning
    lamp and buzzer, to alert the driver that the
    system is about to operate.
  • The DbW ECU is connected to speed signal similar
    to System 80 and, at a pre-set frequency, the ECU
    transmits a signal to the vehicles Engine
    Management System which then holds the vehicle at
    the set speed.

15
System 80 and DbWOptions
  • Top Speed Control with
  • Automatic Dual Speed
  • Self Diagnostic Testing (Digital)
  • The System 80 range of Speed Controls and our DbW
    System are probably the most versatile systems in
    the World, covering a huge range of vehicles with
    the advantage of being
  • Fast fit
  • Economically priced
  • Having internationally recognised approvals

16
System 2000 is an electronically controlled,
pneumatically operated system offering accurate
speed control in all climatic conditions.
System 90 is an electronically controlled,
pneumatic-over-hydraulically operated system
offering accurate speed control in all climatic
conditions.
17
System 2000 and System 90 Operation
  • The System 2000 and System 90 are both controlled
    by an Electronic Control Unit (ECU) mounted in
    the driving compartment of the vehicle.
  • The ECU receives a frequency (speed-related
    signal) from either a Tachograph, speedometer or
    mechanical gearbox sensor.

18
System 2000 and System 90 Operation
  • At a pre-set frequency (speed), for example
    80km/h (50mph), the ECU transmits a signal to
    either the Pressure Proportional Valve (PPV) for
    the System 2000 or the Hydraulic Control Unit for
    the System 90.

19
System 2000 and System 90 Operation
  • This allows the air for the System 2000 or
    hydraulic oil for the System 90 to flow to the
    cylinder mounted in the throttle linkage, causing
    the linkage to be either lengthened or shortened
    and thus controlling the speed of the vehicle
    whilst the pedal is fully depressed.

20
System 2000 and System 90 Options
  • System 2000
  • Top Speed Control with
  • Dual Speed Facility
  • PTO (power take off) Control
  • Lower speed hold Facility
  • System 90
  • Top Speed Control with
  • Automatic Dual Speed Control
  • Both offer accurate speed control in all climatic
    conditions and have numerous approvals

21
  • Autokontrol developed its range of Romatic Road
    Speed Controls to
  • Reduce accidents
  • Reduce maintenance costs
  • Reduce fuel costs by lowering fuel consumption
  • Reduce driver fatigue
  • Increasing road safety for all users and
    improving the environment for everyone

22
  • You could maximise your return on your investment
    with
  • fewer high speed accidents
  • lower insurance premiums
  • fewer staff lost through speeding bans
  • up to 20 reduction in fuel costs
  • reductions in CO2 emissions
  • reduction in vehicle downtime
  • lower maintenance costs
  • longer service life for vehicles major
    mechanical components

23
  • Fuel savings of up to 20 are achieved by
    reducing the top speed and keeping the
    intermediate speeds constant
  • Increasing speed from 40-60mph results in a 34
    increase in fuel consumption
  • Proven test figures as achieved by an articulated
    vehicle (32 ton) on motorway operation

24
Automatic Lubrication Systems
25
Lubrication From the beginning
26
  • Over 30 years ago, the first Oil Lubrication
    Systems were fitted to buses at the request of
    manufacturers
  • The reasons for this were the difficulties
    encountered when trying to lubricate the various
    steering / suspension points due to the bus /
    coach bodywork
  • Most engineers accept that it is easier and more
    efficient to pump lubricant into a bearing in
    motion than to force it into a bearing when static

27
  • Lubrication systems were developed to deliver the
    following benefits to fleet operators
  • Increased productivity, through reduced vehicle
    down time
  • Longer component life
  • Less bearing wear
  • Automatic on-the-move systems have advantages
    over delivering lubricants to static vehicles
  • More efficient application less lubricant lost
  • Natural motion of parts facilitates complete
    coating

28
  • Automatic Oil Lubrication System
  • Electronically timed, pneumatically (air)
    operated
  • Automatic Grease Lubrication System
  • Electronically timed, pneumatically (air)
    operated
  • Automatic Trailer Lubrication System
  • Pneumatically controlled and operated

29
Automatic Grease System
  • Electronically timed, pneumatically (air)
    operated system.
  • The electronic timer, located in the driving
    compartment, sends a signal at regularly timed
    intervals to the solenoid.

30
Vehicle Layout - Grease
The solenoid opens, allowing air to flow to the
grease pump. The pump delivers grease to the
primary system.
31
Distributors
The grease enters the distributors which have
individual metering units which accurately supply
grease to the bearing to be lubricated. When the
timer stops sending the signal, the solenoid
closes and the pump piston under spring pressure
returns to its rest position.
32
Distributors
The pump recharges with grease from the reservoir
and the metering units in the distributors also
reset for the next timed operation of the system.
33
Vehicle Layout Trailer Unit
  • Pneumatically (air) controlled and operated
  • An electronic impulse counter mounted in the
    lubrication control unit receives an impulse at
    each brake
  • Air operates the grease pump once the pre-set
    impulse number is reached

34
  • Simple operation
  • Timer has full test facility with built-in
    monitor plus an anti-overlubrication circuit
  • No maintenance
  • The distributor blocks are made from high quality
    injection-moulded material

  • Quick and simple

35
  • The combined knowledge of road speed controls of
    the Autokontrol team is more than 150 man years
    over the last quarter-century and of automatic
    lubrication systems since 1973
  • Romatic speed controls and lubrication systems
    have been shown to have reliability that only
    comes with this amount of experience and
    attention to detail
  • Autokontrol has extended its range of Romatic
    products through experience of tough climatic
    conditions and attention to customers needs
    around the world
