A computer system comprising processing circuitry configured to: determine, for a vehicle comprising a driver's cabin, that an engine or a motor of the vehicle has been turned off; receive, from a gradient determining device provided on the vehicle, information indicative of the gradient of the ground on which the vehicle stands; receive, from a sensor device of the vehicle, information indicative of the vehicle being in motion; determine, based on information or based on lack of information from an in-cabin sensor of the vehicle, that the driver is outside of the cabin; and control a gear arrangement of the vehicle to engage a forward gear or a reverse gear based on the information from the gradient determining device, in order to counteract movement of the vehicle due to the gradient of the ground.

A battery module (100) for a battery pack (200) of a heavy electric vehicle is provided. The module includes a plurality of battery cells (110), wherein each battery cell includes a degassing valve (112) for releasing gas and/or particles from within the battery cell, and a plurality of venting tubes (120) including at least one venting tube for each battery cell, wherein the at least one venting tube for each battery cell is configured to provide an individual conduit for routing of gas and/or particles (114) from the degassing valve of the battery cell to outside of a boundary of the battery module, and e.g. outside (240) of the battery pack. The individual routing prevents gasses and/or particles from different battery cells to interact, thereby reducing the risk of thermal runaway spread. A corresponding battery pack, battery cell, heavy electric vehicle and energy storage system are also provided.

The present disclosure generally relates to a computer implemented method that has been implemented with the intention to performing sensor analysis in an exhaust gas aftertreatment system (EATS) (204) coupled downstream of an internal combustion engine (ICE) (202). The disclosed methodology is specifically adapted for determining a scale factor for a NOx sensor (214) that is arranged downstream of a position (207) where an amount of a reductant is injected into exhaust gases from the ICE. The present disclosure also relates to a corresponding engine system (200) and a computer program product.

The vehicle (1) comprises a driving cab (2), which is arranged in front of the vehicle and which comprises a chassis (10), a windshield (20), and a shading device (30) arranged inside the driving cab. The shading device (30) comprises a main curtain (31) and a first side curtain (32; 33), which are separate from each other but carried by a common shaft (34), rotatable relative to the chassis, and which are each kinematically linked to the shaft so as to be jointly moved along the windshield selectively downwardly by unwinding from the shaft and upwardly by winding about the shaft. The vehicle further comprises a camera monitoring system (3) that includes at least one camera (40) capturing images of outside the driving cab, and a first display screen (41; 42) arranged inside the driving cab, positioned on a first one of the two lateral sides, respectively left and right, of the windshield, and vertically aligned with the first side curtain but offset from the main curtain. The shading device (30) is configured to change between a first configuration, in which the main curtain and the first side curtain are entirely disposed higher than a top of the first display screen, and a second configuration, in which a portion of the main curtain is disposed lower than the top of the first display screen without the first side curtain covering the first display screen.

Automatic driver seat adjustment in a vehicle based on seat position imaging is disclosed. A computer system in the vehicle receives target seat position data indicating a target seat position of a set in a vehicle. To adjust the seat to the target seat position, imaging media of the seat is captured with the camera. The imaging media includes images of the seat that are indicative of the current seat position of the seat. The media is processed to determine the current seat position relative to the target seat position. The seat position is then controlled with a seat actuator to move the seat to a new seat position that is toward the target seat position. By utilizing a camera, multiple sensors are not required to keep track of seat position and a camera already used for other purposes in the vehicle can be further utilized for automatic seat positioning.

The invention relates to a suspension system (10) for a heavy vehicle (1), the system comprising: a wheel axle (2); wheels (3, 4); a pair of left and right leaf springs (5, 6); wherein each leaf spring (5, 6) is adapted to be connected also to a chassis (7) of the vehicle (1) so as to, while deflecting, allow relative vertical movement between the chassis (7) and the wheel axle (2); an inertial measurement unit (8) arranged at the wheel axle (2) and adapted to provide a signal indicative of a current angular velocity of the wheel axle (2) about a longitudinal roll axis (9) of the vehicle (1); left and right level sensors (11, 12) arranged to provide a signal indicative of a current vertical position of a corresponding leaf spring (5, 6) in relation to the chassis (7); and a control circuitry (13) configured to: compare the signals on current vertical position obtained from the left and right level sensors (11, 12) and determine whether a current difference in vertical position between the left and right leaf springs (5, 6) is greater than a first threshold value; if the determined difference is greater than the first threshold value: determine, based on timing information related to the signals provided by the inertial measurement unit (8) and the left and right level sensors (11, 12), whether the determined difference in vertical position between the left and right leaf springs (5, 6) is related in time with a signal from the inertial measurement unit (8) indicating that the angular velocity of the wheel axle (2) is greater than a second threshold; and, if the determined difference in vertical position is not related in time with the signal indicating that the angular velocity of the wheel axle (2) is greater than the second threshold, generate an alarm signal indicative of a detected or possibly detected leaf spring failure.

A battery housing (100) for holding a plurality of battery cells (102) for a vehicle, the battery housing comprising: a cell compartment (104) comprising an opening (106); a vent channel (108) fluidly connected to the cell compartment via the opening, the vent channel comprising a first outlet (110) and a second outlet (112), each of the first and second outlet being fluidly connected to an outside of the battery housing; and a thermal expansion material (114) arranged in a flow path between the opening and the first outlet, the thermal expansion material being configured to expand to prevent a flow through the first outlet at a predetermined threshold temperature.
