Enligt uppfinningen uppnas syftena med ett forfarande f6r bedonnning av forarbeteende vid framforande av fordon innefattande en drivlina med en vaxellada vilken erbjuder mojlighet till manuell vaxling inbegripande synkronisering, innefattande steget att: vid en vaxling faststalla upptradande varvtalssynkronisering fOr genomforande av den valda vaxlingen for bedonnning av med namnda vaxling forknippade belastning pa forefintliga synkroniseringsorgan som underlag fOr bedOmning av namnda f6rarbeteende.Harigenommojliggors6kadlivslangdhos synkroniseringsorgan hos vaxelladan hos fordonets drivlina i det att vaxlingar som bedoms medfora for stora belastningar pa synkroniseringsorgan harvid kan faststallas och utgora underlag for bedonnning, dar -Waren kan informeras om vaxlingar som medfor onodig belastning pa synkroniseringsorgan for att uppmuntra ett for synkroniseringsorganen mer skonsamt vaxlande och enligt en variant betygsattas darefter for att ge ytterligare incitament till foraren att vaxla pa ett korrekt satt. For vaxellador med vaxlingsservo, dar f6raren far filtrerad aterkoppling i form av kansla och varierat motstand beroende pa hur kraftig rorelsen av vaxelspaken är vid vaxlingen, nnojliggors harigenonn att ge aterkoppling till f6raren dar vaxlingen medfort for stor belastning pa synkroniseringsorgan vid synkroniseringen. Vidare kan fordonsagare och/eller akeri till vilket fordonet är knutet harvid informeras om vaxlingsbeteendet hos foraren. 3 Enligt en utfOringsform av fOrfarande inbegriper steget att faststalla upptradande varvtaissynkronisering stegen att: faststalla den forandring av motorvarvtal namnda \taxiing ger upphov till; och faststalla varvtal hos utgaende axel hos vaxelladan. Harigenom mojliggors ett enkeit och kostnadseffektivt satt att faststalla upptradande varvtaissynkronisering och salunda belastning pa synkroniseringsorgan, dar medel i form av sensororgan for att faststalla motorvarvtal och varvtal hos utgaande axel utgor redan befintliga organ hos fordonet och darvid inte erfordrar nagon ytterligare komponent eller installation. According to the invention, the objects are achieved with a method for assessing forerunner behavior when driving vehicles comprising a driveline with a gearbox which offers the possibility of manual shifting including synchronization, comprising the step of: determining at a shifting occurring speed synchronization for carrying out the selected shifting. said switching associated load on existing synchronizing means as a basis for assessing said driving behavior. This makes it possible to damage the lifespan of the synchronizing means of the gearbox of the vehicle's driveline in that switching which is judged to cause excessive loads on synchronizing means can be fixed. which imposes an unnecessary burden on synchronizing means to encourage a more gentle shifting for synchronizing means and, according to a variant, is subsequently graded to provide additional incentives for the driver to: switch in a correct way. For gearboxes with gearshift servo, where the driver receives filtered feedback in the form of chancellery and varied resistance depending on how strong the motion of the gear lever is at the gearshift, it is sufficient to provide feedback to the driver where the gearshift puts too much load on the synchronizing means during synchronization. Furthermore, vehicle sawmills and / or hauliers to which the vehicle is attached can be informed about the shifting behavior of the driver. According to an embodiment of the method, the step of determining the occurring speed synchronization includes the steps of: determining the change of engine speed the said taxiing gives rise to; and determining the speed of the output shaft of the gearbox. This enables a simple and cost-effective way to determine occurring rotational synchronization and the load on synchronizing means, where means in the form of sensor means for determining engine speed and output shaft speed constitute already existing means of the vehicle and do not require any additional component or installation.

Enligt en utf6ringsform av f6rfarande inbegriper steget att faststalla upptradande varvtaissynkronisering faststallande av det antal vaxlingssteg hos vaxelladan namnda \taxiing motsvarar. Harigenom erhalles underiag f6r bedomning av huruvida foraren vid en \taxiing utfort vaxiingen med ett ur belastning av synkroniseringsorgan vid synkronisering lampligt antal vaxiingssteg, vilket beror pa situation inbegripande kornnotstand sasom vagiutning. Exempeivis är en \taxiing i form av en uppvaxiing med fiera vaxiingssteg vid ett kraftigt motiut en olamplig \taxiing vad avser belastning pa synkroniseringsorgan. According to one embodiment of the method, the step of determining occurring rotational synchronization involves determining the number of shifting steps of the gearbox called taxiing. This provides a basis for assessing whether the driver, during a taxi, performed the waxing with a number of waxing steps suitable from the load of the synchronizing means during synchronization, which depends on the situation, including grain resistance such as voyage. For example, a taxiing in the form of a waxing with several waxing steps at a strong motion is an unsuitable taxiing in terms of load on synchronizing means.

Enligt en utforingsform innefattar forfarande steget att faststalla den effekt som motsvarar namnda upptraciande varvtaissynkronisering vid namnda belastning pa forefintliga synkroniseringsorgan som underiag for bedomning av narnnda forarbeteende. Harigenom erhalles en noggrannare faststalining av konsekvensen av den aktuella vaxlingen och den dar upptradande varvtaissynkroniseringen vilket ger ett battre underiag for bedomning av forarbeteendet avseende vaxling. According to one embodiment, the method comprises the step of determining the effect corresponding to said occurring rotational synchronization at said load on existing synchronizing means as a basis for judging said preparatory behavior. This results in a more accurate determination of the consequence of the current switching and the subsequent rotating synchronization, which provides a better basis for assessing the preparatory behavior regarding switching.

Enligt en utforingsform av forfarande inbegriper steget att faststalla narnnda effekt faststallande av den tid som namnda varvtaissynkronisering tar i ansprak. Genom att salunda beakta synkroniseringstiden mojliggors ett enkeit satt att faststalla medeleffekten under synkroniseringen. 4 Enligt en ufforingsform av forfarande sker faststallandet av den tid som namnda varvtalssynkronisering tar i ansprak baserat pa position och fOrandring av position hos vaxelspaken och/eller motsvarande organ i vaxelladan. Genom att salunda beakta och harvid faststalla forandringar i vaxelspakslage och/eller motsvarande organ sasom skiftgafflar mOjliggOrs ett effektivt satt att faststalla synkroniseringstiden och harvid medeleffekten. Synkroniseringstiden bestams enligt en variant genom att mata tiden som vaxelspakslage och/eller motsvarande organ sasom vaxlingsgafflar befinner sig i ett fordefinierat synkroniseringslage. For att uppna storre sakerhet kan aven derivatan pa dessa positioner utvarderas, dar derivatan är noll eller lag i synkroniseringslaget. According to one embodiment of the method, the step of determining said power comprises determining the time taken by said rotary synchronization. By thus taking into account the synchronization time, it is possible to easily determine the average power during the synchronization. According to an embodiment of the method, the time taken by said speed synchronization is determined based on the position and change of position of the gear lever and / or corresponding means in the gearbox. By thus taking into account and thereby determining changes in gear lever stroke and / or corresponding means such as shift forks, an effective way of determining the synchronization time and thereby the average effect is possible. The synchronization time is determined according to a variant by feeding the time as a gear lever stroke and / or corresponding means as if the shift forks are in a predefined synchronization stroke. In order to achieve greater certainty, the derivative at these positions can also be evaluated, where the derivative is zero or law in the synchronization law.

Enligt en ufforingsform av f6rfarande sker faststallandet av den tid som namnda varvtalssynkronisering tar i ansprak baserat pa forandring hos varvtal hos vaxelladans sidoaxel. Genom att salunda beakta och harvid faststalla forandringar hos varvtal hos vaxelladans sidoaxel nnojliggors ett effektivt satt att faststalla synkroniseringstiden och harvid effekten. Da varvtalsskillnadenochvarvtalsskillnadensderivata,alltsa vinkelaccelerationen, kan bestannnnas i varje diskret tidssteg i vaxelladsstyrenheten sa kan aven en momentan, tidsberoende, effekt beraknas. Detta ger battre bedomning av det resulterande slitaget an medeleffekt ger. Hansyn kan aven tas till temperaturberoende slapforluster, t.ex. genom att mata eller uppskatta oljetemperaturen och berakna de resulterande slapforlusterna. According to one embodiment of the method, the time taken by said speed synchronization is determined based on a change in speed of the side shaft of the gearbox. By thus taking into account and at the same time determining changes in speed of the side shaft of the gearbox, an efficient way of determining the synchronization time and of the effect is made possible. Since the speed difference and the speed difference derivative, i.e. the angular acceleration, can be determined in each discrete time step in the gearbox control unit, a momentary, time-dependent, effect can also be calculated. This gives a better assessment of the resulting wear than the average power gives. Hansyn can also be taken for temperature-dependent slack losses, e.g. by feeding or estimating the oil temperature and calculating the resulting slap losses.

Enligt en ufforingsform av forfarande inbegriper bedomning av med namnda vaxling forknippade belastning pa forefintliga synkroniseringsorgan som underlag for bedomning av namnda forarbeteende steget att taga hansyn till aktuellt kormotstand vid namnda vaxling. Genom att salunda taga hansyn och harvid faststalla aktuellt kormotstand vid vaxlingen erhalles ett battre underlag f6r bedomning av huruvida vaxlingen utf6rts pa ett f6r synkroniseringsorganen skonsamt satt under radande forhallande beaktande mojligheten till framforande av fordonet. According to one embodiment of the procedure, the assessment of the load associated with said waxing on existing synchronizing means as a basis for judging said preparatory behavior includes the step of taking into account the current choir resistance at said waxing. By taking this into account and thereby determining the current choke resistance at the changeover, a better basis is obtained for assessing whether the changeover was carried out in a way that the synchronizing means were gently placed under radiating conditions, considering the possibility of driving the vehicle.

Enligt en utforingsform av f6rfarande sker bed6mning av med namnda vaxling forknippade belastning pa forefintliga synkroniseringsorgan som underlag for bedomning av namnda fOrarbeteende mot bakgrund av referensdata avseende gransvarden speglande nojaktig belastning vid sadan vaxling. Harigenom mOjliggOrs ett enkelt och effektivt satt att bedOma forarbeteendet avseende vaxling. Vidare underlattas betygsattning for fOrarbeteendet avseende \taxiing. According to an embodiment of the method, the load associated with said wobbling is assessed on existing synchronizing means as a basis for judging said driving behavior in the light of reference data concerning the spruce guard reflecting an accurate load at such wobbling. This makes it possible for a simple and efficient way to assess the preparatory behavior regarding waxing. Furthermore, grading for driver behavior regarding taxiing is omitted.

Enligt en ufforingsform innefattar forfarande steget att f6r fordonets forare presentera bedOmning av fOrarbeteende avseende utfOrda vaxlingar. Harigenom nnojliggors forbattrat fOrarbeteende i det att -Waren uppmarksammas pa vaxlingar som medfOr onOdig belastning pa fOrefintliga synkroniseringsorgan. Foraren kan harvid vid presentationen fa betyg baserat pa forarbeteendet avseende vaxlingar. Harvid mojliggors ytterligare forbattrad livslangd hos synkroniseringsorganen. F6rfarandet innefattar enligt en variant aven att for fordonsagaren och/eller akeriet till vilket fordonet är knutet presentera bedomning av forarbeteende avseende utforda vaxlingar. Fordonsagaren och/eller akeriet till vilket fordonet är knutet kan harvid vid presentationen fà forarens betyg baserat pa forarbeteendet avseende vaxlingar. According to one embodiment, the method comprises the step of presenting to the driver of the vehicle an assessment of driver behavior regarding performed shifts. This facilitates improved behavior in that the -Ware is noticed on shifts that cause unnecessary strain on existing synchronizing means. At the presentation, the driver can receive grades based on the preparatory behavior regarding shifts. This makes it possible to further improve the service life of the synchronizing means. According to a variant, the method also comprises presenting to the vehicle sawmill and / or the haulier to which the vehicle is attached an assessment of forerunner behavior with regard to challenging shifts. The vehicle owner and / or the haulier to which the vehicle is attached may at the presentation receive the driver's rating based on the preparation behavior regarding shifts.
