The present invention relates to a method for an economical cruise control and to an economical cruise control which demands from an engine system a reference speed vref which may differ from a chosen set speed vset.

A user of the economical cruise control is thus provided with an increased feeling of control over the vehicle's speed.

There is therefore a huge gap, in urban areas, between the individual perception of economic speed and the collective measure of socio-economic speed.

6 For a minimum-wage worker, the economic speed is 32km/h and the socio-economic speed is barely more than 1km/h.

The adjustment is based at least partly on input from a user of said economical cruise control.

These results can be integrated into the calculation of economic speed.

Cruising range at economic speed reaches 4850 nautical miles.

The range at a cost effective speed of 12 knots is 5,000 nautical miles.

The range at the speed of 12 knots is 5,000 nautical miles.

When more than a certain amount of mileage data is stored, the economic speed is calculated relative to the stored mileage data, and the calculated speed is displayed on a display unit.

Given the social costs they require, the socio-economic speed of cars in an urban setting, from the community’s point of view, is much lower than the economic speed is for the individual user.

The object of the invention is to provide a cost-effective gearbox with an automatic mode which can transmit high torques and avoid a total load interruption during gear shifts or changes in transmission ratio.

The range data given by our factory is also tested at economic speed.

When the car runs in the economy speed is the most fuel efficient .

As car prices have fallen, the ‘economic speed’ 3 of passenger cars has quadrupled;
