Abstract: A vehicle door positioning holder includes a hydraulic cylinder connected to the door and a vehicle chassis, and a brake hydraulically connected in a loop. The cylinder pushes hydraulic fluid in the loop when the door is moved. The brake includes first and second chambers hydraulically connected to the loop and a third chamber connected in the loop at respective ends to the first and second chambers. The brake has a ball element in the third chamber when the hydraulic fluid is still, moved towards the first chamber as the hydraulic fluid flows in a first direction, and moved towards the second chamber as the hydraulic fluid flows in a second direction. A flow resistance of the hydraulic fluid is larger when the ball is positioned in the third chamber than when the ball is moved towards the first or the second chambers.

Abstract: A cable includes a first conductor and a first conductor isolation, wherein the first conductor includes at least a first break point between the first and second end of the cable and the first conductor isolation includes at least a second break point between the first and second end of the cable, the cable is configured so that the first conductor breaks at the at least first break point if the cable is exposed to a force that is above a first predetermined limit and first conductor isolation breaks at the at least second break point if the cable is exposed to a force that is above a second predetermined limit for avoiding hazardous electric shock after a crash of the vehicle.

Abstract: A wheel suspension arrangement including a suspension spring, at least one control member arranged to control a stiffness of said suspension spring. The control member is displaceable relative to said suspension spring between a retracted position, in which the control member does not interfere with an operation of the suspension spring, and an advanced position, in which it interferes with the operation of the suspension spring in a way that the stiffness of said suspension spring is increased. The wheel suspension arrangement further includes a biasing means configured to bias said control member towards said retracted position.

Abstract: A power supply system for an electric vehicle drivetrain includes series connected first and second high-voltage battery units, a circuit arrangement having high-power switching semiconductor devices connected to the battery units, and an electronic control system. During a charging mode, the control system controls the semiconductor devices to route high-voltage DC from a vehicle external charging source alternatingly to the battery units. During a power supply mode, the control system controls the operation of the semiconductor devices to supply high-voltage DC from both the battery units for driving a vehicle electrical traction machine of the electric vehicle drivetrain, wherein the supplied high-voltage DC has a voltage level corresponding to an accumulated voltage level of the series connected battery units.

Abstract: A vehicle power supply system provides redundant high-voltage and low-voltage power supply for an electric vehicle or a hybrid-electric vehicle. The power supply system includes first and second high-voltage battery units. A positive terminal of the first unit is connected to a positive power distribution arrangement and a positive terminal of the second unit is connected to a negative terminal of the first high-voltage battery unit via an intermediate power distribution arrangement, and a negative terminal of the second unit is connected to a negative power distribution arrangement. The system has a first bypass line connecting the positive power distribution arrangement with the intermediate power distribution arrangement, and a second bypass line connecting the negative power distribution arrangement with the intermediate power distribution arrangement.
