Abstract: The present invention relates to a method for automatically establishing an updating a table of distances by means of a vehicle which is equipped with a computer unit and a trip meter, which vehicle is driven along a route extending past a group of predetermined stops which are represented in a list stored in a computer unit. Each time the vehicle stops at a stop, the computer unit receives from the trip meter data which represents a distance that has been covered since the preceding stop. If the list lacks information about said distance, the data is stored in the list associated with the current location, whereas if the list already contains information about said distance, the data is allowed to affect the information by suitable statistical processing. By means of this method, a table of distances is automatically established, and is also updated each time the vehicle stops at a location along the route.

Abstract: The invention relates to a method of storing information in the form of signals from a control system in a vehicle, said method comprising the step of reading a signal on recurrent sampling occasions and increasing the value of a counter which represents a signal value interval. The method further comprises the steps of measuring on each sampling occasion a change of the signal in relation to a previous signal value, comparing change with the threshold value, and, if the change is greater than the threshold value, increasing the value of a counter associated with this threshold value.

Abstract: The invention relates to a method and a device for assisting a driver of a vehicle, said vehicle having an engine and a braking system, an accelerator that conveys the driver's wishes concerning acceleration to the engine, and a brake pedal that conveys the driver's wishes concerneing retardation to the braking system. In accordance with the method a speed profile is determined for the driving distance, which speed profile comprises a relation between a speed set point and position. Furthermore, the engine and the braking system are controlled on the basis of the speed profile and at least one actuator influences the accelerator or braking pedal of the vehicle in accordance with said control. The driver is permitted to override the influence of the actuator only if a force that is greater than a predetermined threshold value is applied on one of the pedals.
