The present disclosure relates to estimated road geometries used in vehicles, and in particular to a method and a control unit in a vehicle for determining a confidence level of an estimated road geometry. A method for determining a confidence level of an estimated road geometry is disclosed. The road geometry being estimated at least partly based on a position of a road object. The method comprises obtaining (S1) a reference position of the road object relative to the vehicle, updating (S3) a reach of a confidence zone of the vehicle, wherein a part of the estimated road geometry comprised within the confidence zone is associated with one or more reference confidence levels, and determining (S5) the confidence level of the estimated road geometry based on whether the reference position is comprised in the confidence zone.

The present invention relates to a system for controlling driving modes of a vehicle having a driver, wherein each of said driving modes is adapted to control a behaviour of said vehicle during operation of the vehicle in said driving mode, each of said driving modes being associated with a set of driving sub-modes, wherein each driving sub-mode is adapted to be activated by the vehicle in response to ambient circumstances. One of said driving modes is associated with a first and a second driving sub-mode, said first and second driving sub-modes being accompanied with a first and a second driver controlled setting respectively. The system further comprises input means for selection between said driving modes and for controlling said driver controlled settings when applicable, wherein said first and second driver controlled settings are adapted to be manually set by the driver through said input means only upon activation of the accompanying driving sub-mode by the vehicle. <img class="EMIRef" id="147521874-iaf01" />

The invention relates to a transmission for a motor vehicle, wherein the transmission (10) comprises an input shaft (20) and at least a first and second countershaft (30; 40), and an output shaft (50), wherein the input shaft (20) is provided with a first driving gearwheel (21), which interacts with a first gearwheel (31) arranged upon the first countershaft (30), and a second gearwheel (41) arranged upon the second countershaft (40) wherein the first and second countershaft (30, 40) further is provided with a first and second output gearwheel (32; 42) respectively, which interacts with a common final drive gearwheel (51) arranged upon the output shaft (50). A number of gear teeth (n31) of the first gearwheel (31) is selected such in relation to the number of gear teeth (n21) of the first driving gearwheel (21), that the number of gear teeth (n31) of the first gearwheel (31) can be either reduced or increased with at least one gear tooth, without affecting the number of gears teeth (n21) upon the first driving gearwheel (21), vvhereby the reduction or increase the number of gear teeth (n31) of the first gearwheel (31) is compensated with a profile shift of the gear teeth of the first gearwheel (31).

Embodiments herein relate to a method for calibrating a sensor cluster (1) which is located at an inside of a windshield (2) of a motor vehicle (3) and arranged such that the pitch thereof is adjustable. The sensor cluster (1) at least comprises a narrow beam sensor (4) and an imaging sensor (5) both of which are directed forward of the motor vehicle (3). An angle gamma (y) between the center directions (6, 7) of the narrow beam sensor (4) and the imaging sensor (5) of the sensor cluster (1) has been pre-calibrated and stored in at least one memory unit (8, 9). The method comprises the steps of: calibrating at least one of the narrow beam sensor (4) and the imaging sensor (5) of the sensor cluster (1) with respect to a geometrical travel axis (10) of the motor vehicle (3); recording a measure epsilon (µ) corresponding to an angle between a center direction (7) of the imaging sensor (5) and a reference provided by a fixed vehicle (3) structural part (11); and storing the recorded measure epsilon (µ) in the at least one memory unit (8, 9).

The present disclosure relates to an arrangement (27, 56, 68, 74) comprising a pyrotechnical device (26, 60, 86), and a first mechanical structure (12, 58, 78). The pyrotechnical device is adapted to, directly, or indirectly, influence the first mechanical structure at a first location, such that the first mechanical structure is exposed to a deformation and/or a displacement. The deformation and/or displacement of the first mechanical structure at the first location is adapted to at a second location, being different from the first location, change a functional mode of the first mechanical structure and/or of a second mechanical structure (16, 70) connected to the first mechanical structure by means of direct mechanical influence. The disclosure further relates to a vehicle (10) comprising such an arrangement. (27, 56, 68, 74).
