The present disclosure relates to a bonnet deployment arrangement (11, 11', 11 ") adapted to be located at an end portion (17) of a bonnet (5) of a vehicle (3). The bonnet deployment arrangement is transferable from a normal state to a deployed state and comprises a first portion (19, 19', 19") adapted to be attached, directly or indirectly, to the bonnet, a second portion (21, 21', 21 "), comprising one of a striker (15) or a latch for retaining the bonnet in a closed position, a pivot arm (23, 23', 23"), and a locking unit (25, 25', 25") having a locked state and an unlocked state. The pivot arm is rotatably connected to the first portion at a first axis (A1, A1") and rotatably connected to the second portion at a second axis (A2, A2"). The first portion is locked relative to the second portion in the locked state of the locking unit. The first portion is movable in relation to the second portion by means of the pivot arm rotating at the first axis and at the second axis in the unlocked state of the locking unit, the bonnet deployment arrangement thereby being transferable from the normal state to the deployed state. The invention also relates to a bonnet arrangement for a vehicle and to a method of transferring a bonnet deployment arrangement from the normal state to the deployed state.

The invention relates to a method for operating a compression ignition internal combustion engine (10) including at least one combustion chamber (18) with a fuel injector (20) for direct fuel injection into a combustion chamber (18), an electronic control unit (ECU) for controlling the fuel injector, and a glow plug (26) for assisting compression ignition of the fuel and combustion air mixture supplied to the combustion chamber (18) in a start phase (T). The method involves performing a by injecting a start-up pilot fuel quantity, prior to a stratified injection, by means of the fuel injector (20) into the combustion air supplied to the combustion chamber (18) during a cold start of the internal combustion engine (10), said start-up pilot injection (PS) forming a homogeneous, lean air/fuel mixture in substantially the entire combustion chamber (18). The start-up pilot injection is performed during a period between initialization of a cranking phase of the internal combustion engine until at least one predetermined engine operating condition has been fulifilled.

An adjustable child seat (1) comprising a seat support portion (4) adjustable between at least a first height position and a second height position, the seat support portion (4) comprising a first seating surface (4a), wherein the adjustable child seat (1) further comprising at least a first lamella (6) comprising a second seating surface (6a), wherein the first lamella (6) is pivotally connected to the seat support portion (4), wherein the first lamella (6) is adapted to be in a first position whereby the seat support portion (4) is in the first height position, wherein the second seating surface (6a) is essentially non-parallel to the first seating surface (4a), wherein the first lamella (6) is adapted to be pivoted to a second position wherein the seat support portion (4) is in the second height position, wherein the second seating surface (6a) is essentially parallel to the first seating surface (4a).

The present disclosure relates to a bonnet latch bracket arrangement (4, 4') for a vehicle (2, 2'), which arrangement is adaptable to different vehicle models, the arrangement comprising - a bonnet latch (12), - a bracket member (14, 14'), and - a vehicle body member (10), the bonnet latch being attachable to the vehicle body member by means of the bracket member, the bracket member being adapted to take up dimensional differences between the bonnet latch and the vehicle body member in a longitudinal, lateral and/or height direction of the vehicle, and the adaptability to different vehicle models being achieved by varying the geometry of the bracket member according to the dimensions of the vehicle model. The disclosure further relates to a modular system for configuration of a bonnet latch bracket arrangement to different vehicle models and a method for adapting a bonnet latch bracket arrangement to fit in different vehicle models.

The present invention relates to a safety system for avoiding or mitigating a collision with other road users. The safety system comprises a monitoring means (1) for monitoring a road for detecting the relative approach of road users to said vehicle and providing a first signal indicative thereof. The safety system also comprises first and second managing means (2, 6) which are operatively connected to the monitoring means (1) and connected in parallel for activating, in response to the first signal, active and passive safety means (4, 8) respectively. Finally, there is also a detecting means (10) for detecting a collision with another road user and providing a second signal indicative thereof. The detecting means (10) is operatively connected to the passive safety means (8) for controlling, by means of the second signal, the activation of the passive safety means. Thus, the present invention optimizes data input for passive safety functions through use of two different managing means which are optimized for passive safety functions and active safety functions respectively, in combination with a detection means to detect collision events.

Device and method for safety stoppage of an autonomous road vehicle (2) having a localization system (3) and sensors (4) for monitoring the vehicle (2) surroundings and motion, and a signal processing system (5) for processing sensor signals enabling an autonomous drive mode thereof. Processing means (7) continuously: predict where a drivable space (8) exists; calculate and store a safe trajectory (10) to a stop within the drivable space (8); determine a current traffic situation; determine any disturbances in sensor data, vehicle systems or components enabling the autonomous drive mode. If an incapacitating disturbance is determined, a request for a driver to take over control is signaled and determined if a driver has assumed control within a pre-determined time. If not, the vehicle (2) is controlled to follow the most recent safe trajectory (10) to a stop in a safe stoppage maneuver during which, or after stopping, one or more risk mitigation actions adapted to the determined current traffic situation are performed.

There is provided a method for activating warning lights (206) in a vehicle (200), the method comprising: determining (102) a yaw rate (202) of the vehicle; determining (104) a sideslip angle (204) of the vehicle (200); comparing (106) the yaw rate (202) to a predetermined yaw rate threshold value; comparing (108) the sideslip angle (204) to a predetermined sideslip angle threshold value; and if the yaw rate (202) exceeds the predetermined yaw rate value; if the sideslip angle (204) exceeds the predetermined sideslip angle value; and if it is determined that the vehicle (200) reaches a standstill within a predetermined time after the yaw rate and sideslip values have been exceeded, activating (112) warning lights (206) of the vehicle (200). There is also provided a system configured to perform the above described method.
