Abstract:
The present disclosure relates to a method and device for operating a powertrain of a motor vehicle, wherein the powertrain comprises an internal combustion engine, a transmission and a friction clutch arranged there between in order to control a power flow between the internal combustion engine and the transmission. The method comprises the steps of detecting clutch judder, analysing clutch judder, and determining a type of clutch judder. Based on determined type of clutch judder the method further comprises selecting a judder countermeasure from a number of predetermined judder countermeasures and executing selected judder countermeasure. The present disclosure has the effect that detected clutch judder can be taken care of in the currently most efficient way and that future clutch judder may be prevented.

Des Weiteren betrifft die Erfindung ein Fahrzeug.
Abstract:
A method and system for adapting a vehicle control strategy of an on- road vehicle following a reoccurring fixed route to a predetermined destination, which fixed route extends through at least one geographical zone associated with at least one environmental restriction. When it is determined that the vehicle is approaching the geographical zone, historical data collected from previous passages of one or several vehicles through the zone is accessed, and the vehicle control strategy inside the geographical zone is adapted based on the historical data and the environmental restriction. The invention is based on the insight that vehicles travelling along a reoccurring route may have significant use of historical data relating to previous passages along the route when adapting a vehicle control strategy.
Abstract:
The invention relates to a method of controlling inter-vehicle gap(s) (24a-c) in a platoon (10) comprising a lead vehicle (12) and one or more following vehicles (14a-c). The method comprises the steps of: obtaining an indicator (27) of a potential collision threat (26) identified by an autonomous emergency braking system (16) of the lead vehicle, wherein the autonomous emergency braking system of the lead vehicle comprises predefined control phases (28a-c), and wherein the indicator at least partly determines a current control phase of the autonomous emergency braking system; and sending the obtained indicator to the one or more following vehicles.

Abstract:
Energy control system for a hybrid vehicle with at least one electrical machine and a combustion engine and at least one chargeable energy store, which system comprises a control unit and a charge level meter which is adapted to measuring the charge level of the energy store. The control unit comprises a calculation unit adapted to calculating at a time t 0 , inter alia on the basis of the vehicles current speed and weight, a time t 1 which denotes the beginning of a retardation phase during which the vehicle is braked in order to halt at a predetermined location P, and the control unit is adapted to controlling the offtake of energy from the energy store during the period from t 0 to t 1 so that the charge level of the energy store at time t 1 is below a predetermined low level Q L .
Abstract:
The present invention relates to a method of controlling at least a first function of a vehicle, wherein the said vehicle comprises means for determining a parameter value representing the load on at least one axle, wherein the method comprises the steps of determining a parameter value representing a load on the said at least one axle, and if the said parameter value is below a first threshold, operating the said first vehicle function according to a first operating mode, and if said parameter value is above the said first threshold, operating the said first function according to a second operating mode, the said second operating mode being different from the said first operating mode, wherein at least one of the said operating modes is a chassis mode for use at vehicle chassis prior to the chassis being subject to a body build. The invention also relates to a device and a vehicle.
Abstract:
The invention relates to a method (30) for controlling a vehicle (1) having at least one first and second drive axle (2, 3), wherein at least one first drive device (6.1, 6.2) is assigned to the first drive axle (2) and at least one second drive device (7.1, 7.2) is assigned to the second drive axle (3), wherein the method comprises the following steps: detecting (31) a first axle load value (m_1) for the first drive axle and a second axle load value (m_2) for the second drive axle; specifying (32) a total torque (M_Ges) which is to collectively affect the first and second drive axles; and dividing (33) the total torque into a first and second target torque (M_Soll_1, M_Soll_2) depending on the first and second axle load value for the first and second drive axle.
