BACKGROUND Economic grinding through efficient utilization of the vehicle's kinetic energy in vehicles such as trucks for fuel-saving purposes is becoming increasingly common. One way to do this is to minimize the use of brakes on downhill slopes. This is done in particular by the driver relaxing the gas well before the downhill slope and clamed throttling the fuel supply with a speed reduction as follows. This lost speed is then repeated "for free" on the downhill slope.
It is' Edge to use the cruise control of the vehicle to drive the vehicle economically, where the cruise control with the help of the vehicle's position and map data along the vehicle's lane affects the vehicle's speed based on what the topology in front of the vehicle looks like.
However, it is not always convenient to use the cruise control, for example on curvy and hilly roads. On such roads, however, the need to utilize the vehicle's kinetic energy for fuel-saving purposes may be greater and the requirements 2 on the driver correspondingly higher. Some drivers also choose not to use the cruise control. Consequently, industry economic advancement is defended in situations where cruise control is based on map data along the route into use.

This facilitates reduced fuel consumption when the vehicle is cranked. By presenting proposals to the driver as well as reducing throttle traction, ie. relax the throttle, alternatively deactivate the vehicle's normal cruise control function which keeps the vehicle's speed at a set speed, ie. deactivate the vehicle's cruise control, in good time before a downhill slope is given to unfamiliar drivers good help on the road to adopt an economic spinal cord behavior in their cranking. It can also help experienced drivers such as Mr on a road where the terrain is difficult to answer, such as curvy roads or roads where the speed on an upcoming downhill slope is the answer to danger.

The electronic control unit 100 is arranged to determine whether additional side conditions are met in the inferior passage. According to one embodiment, said ancillary conditions include one or more of the ancillary conditions that the throttle must be present, that the vehicle's cruise control function must not be activated, that the vehicle must not be in a performance layer where industry economy is subordinate, and that the vehicle's speed must not be less than a predetermined speed. 13 Due to the additional condition that gas path traction must be present, it is avoided to present proposals for gas path traction reduction as such gas path traction reduction is not possible and consequently unnecessary disruption of the driver. The electronic control unit 100 is consequently arranged to process said gas path traction data in order to determine the degree of gas path traction, i.e. determine whether the driver has depressed the accelerator pedal.
Due to the additional condition that the vehicle must not be in a performance layer where the fuel economy is subordinate, it is avoided to present proposals for throttle reduction as such throttle reduction is not justified as the driver has chosen to prioritize other than fuel economy such as passability.
The electronic control unit 100 is consequently arranged to process said data for which mode the vehicle bites into, i.e. if the vehicle is in performance law or economy law.
Due to the additional condition that the vehicle's speed must not be less than a predetermined speed, it is avoided to present proposals for throttle reduction as the vehicle's speed is such that the dot is not justified and does not entail any industry economic advantage. Accordingly, the electronic control unit 100 is arranged to process said speed data and compare said speed data with said predetermined speed in order to determine whether the speed of the vehicle is less than the predetermined speed.
If the said conditions are met, the electronic control unit 100 is arranged to send a signal to said action proposal presentation means 160 via the link representing action proposal data to present proposals to the driver to reduce throttle traits for undesired reduced fuel consumption in the coming crown.
The electronic control unit 100 is arranged to determine whether the velocity profile as a result of acceleration with increased motor torque during the crowning course satisfies certain side conditions. According to an embodiment of the method, said side conditions comprise that the speed of the vehicle relative to a reference speed of the vehicle when accelerating with increased engine torque must drive at a predetermined speed and in a subsequent uphill slope decrease at a predetermined speed. According to a variant, the conditions for these speeds depend on the said reference speed. According to a variant, the conditions for these speeds depend on the mass of the vehicle.
This improves the possibility of avoiding a downshift, which thus facilitates reduced fuel consumption. Furthermore, this enables time savings to, for example, make up for time lost during speed reductions. According to an example, the said condition could be that given substantially full throttle, ie. acceleration with INCREASED torque, then the vehicle speed must increase by, for example, 2 km / h, which must then decrease by, for example, at least 4 km / h in the uphill slope despite maximum torque.
Fig. 3 schematically illustrates a velocity profile as a result of a certain atgard info! ' a crown passage according to an embodiment of the present invention.
According to one embodiment, said side conditions comprise that the speed of the vehicle relative to a reference speed of the vehicle at reduced throttle travel must decrease to a predetermined maximum extent before said crown passage. Said reference speed vref is constituted according to an embodiment of the vehicle's speed before crane passage before throttle reduction. According to an alternative variant, said reference speed vref can be load-dependent.
Accordingly, the electronic control unit 100 is arranged to determine whether the speed of the vehicle relative to the reference speed of the vehicle at reduced throttle travel will decrease to a predetermined maximum extent before said crown passage.
Said predetermined extent is determined according to a variant by vref * Ci where Ci may be a constant or a variable which is between 0 and 1, for example constitutes a percentage of the reference speed vref. According to a variant, Ci is a function of the reference speed vref. Ci is according to a variant dependent on vehicle mode where C1 according to a variant is about 12% below during the economy and during normal operation maybe 6-8% below the reference speed Vref • Said reference speed vref can according to a variant be speed in front of a steep slope of a downhill slope, the vehicle being heavily loaded.
The vehicle will then lose speed. If, for example, the vehicle wishes to keep 80 km / h and accelerate 80 km / h into the uphill slope, the speed is reduced to, for example, 50 km / h in the uphill slope. Then it is undesirable that 80 km / h is the desired speed and thus the reference speed is twisted, whereby one wants to avoid the vehicle losing additional speed, for example from km / h to 45 km / h, whereby reports to passengers about throttle reduction are not given.
Due to the additional condition that the vehicle speed v relative to a reference speed of the vehicle at reduced throttle travel must decrease to a predetermined maximum extent before said crane passage avoids that the crane crest is perceived as unnatural for the driver, where a wrong 'large speed reduction before a crane passage could be experienced unnatural. The risk that the driver ignores the presented proposal for a reduction in throttle traction is thereby reduced, whereby the probability that the violation entails a reduction in fuel consumption increases.
According to one embodiment, said side conditions comprise that the speed of the vehicle relative to a reference speed of the vehicle at reduced throttle travel must decrease to a predetermined minimum extent before said crown passage.
Due to the additional condition that the vehicle's speed v relative to a reference speed of the vehicle at reduced throttle travel must decrease to a predetermined minimum extent before said crane passage is avoided, presenting proposals for throttle reduction if the throttle reduction into entails any significant difference, ie. does not entail any real reduction in fuel consumption in connection with the crown grain.
The electronic control unit 100 is consequently arranged to determine whether the speed of the vehicle v relative to the reference speed of the vehicle 16 at reduced throttle travel will decrease to a predetermined minimum extent before said crown passage.
Said ferrite-determined extent is determined according to a variant by vref - C2 dar 02 can be a constant or a variable. 02 is according to a variant a function of the reference speed Vro. 02 ar according to a variant in the order of 0-5 km / h, according to a variant 1-3 km / h, for example about 1.5 km / h.
According to one embodiment, said additional conditions include that the vehicle speed v relative to a reference speed vref has the vehicle at reduced throttle travel must reach or exceed said reference speed vref after said crown passage. As a result, no proposal is presented for a reduction in the throttle path for the driver as the risk that the crown grain will be perceived as unnatural and the reduction will not lead to any significant reduction in fuel consumption.
Due to the additional condition that the speed of the vehicle v relative to a reference speed vref has the vehicle at reduced throttle travel must reach. or Exceeding said reference speed after said crown passage is avoided to present proposals for throttle reduction if the throttle reduction does not mean that the vehicle at least reaches and heist exceeds the reference speed vref which according to a variant is the vehicle's speed before throttle reduction.
This avoids that the cornering is perceived as unnatural for the driver, where the driver could experience it as unnatural that the vehicle after the cornering does not roll up or exceed the speed the vehicle had before the throttle reduction. The risk that the driver ignores the presented proposal for a reduction in throttle stroke is thereby reduced, whereby the probability that the driver will lead to a reduction in fuel consumption increases.
Accordingly, the electronic control unit 100 is arranged to determine whether the speed of the vehicle relative to the reference speed of the vehicle at reduced throttle travel will reach. or Exceed said reference speed after said crown passage. The said predetermined extent is determined according to a variant by vref - C3 where C3 can be a constant or a variable. According to a variant, C3 is a function of the reference speed vrei. 03 is according to a variant in the order of 0-5 km / h, according to a variant 1-3 km / h, for example about 2 km / h.
