AUTOMATIC REGULATION OF SPEED WINS A PRIZE

AUTOMATISK HASTIGHETSBEGRAENSNING GAV STIPENDIUM

A new invention by a haulier automatically regulates the speed of a lorry-trailer combination. The electronic instrument is connected to the red light on the tachograph and actuates the engine brake when this light comes on. The speed is kept at 70 km/h with some margin. If greater acceleration is needed on a steep hill or for overtaking, a push button disengages the regulator for 90 seconds. There is a delay unit to prevent shunting. There is also a safety device to prevent sudden engagement of the engine brake which could cause jack-knifing on a slippery road. The gains are considerable. On a Scania combination which does 150000 km per year, petrol consumption has been reduced by about 6000 litres. This alone repays the cost of the regulator - skr. 1000 - in less than a month. Other advantages are lower lubricant consumption, less tyre wear, less brake wear, and a better working environment for the driver who need no longer watch the speedometer. (TRRL)
