摘要： Various embodiments of the teachings herein include a method for controlling a cam using an ECU (electronic control unit) comprising: learning a holding region in which linearity is not ensured by increasing or decreasing a PWM signal while the cam maintains a holding state; based on the results of the learning, generating a final PWM signal; and transmitting the final PWM signal to an oil control valve. The final PWM signal comprises a sum of a minimum PWM signal for the cam to leave the holding region and a control PWM signal for the cam to reach a desired position.

摘要： Various embodiments include methods for identifying a malfunction of a DC voltage charging connection in an electric vehicle. An example includes: driving two contactors into an open or closed state without applying a charging voltage; applying an internal reference DC voltage of the electric vehicle between both contactors, including applying a positive pole of the reference DC voltage at the first contactor and a negative pole at the second; measuring a first voltage potential between the contactors on a respective output side; measuring a second voltage potential between the contactors on a respective input side of the contactors; and identifying a malfunction of the two contactors based at least in part on the first voltage potential and the second voltage potential.

摘要： A seal for use in a fluid valve, or multi-path fluid valve, has a cylindrical, resilient base member, a plurality of first sealing portions arranged at an outer side of the base member for sealing abutment against a valve housing of the fluid valve, and a plurality of second sealing portions, arranged at an inner side of the base member, for sealing abutment against an adjustable valve body of the fluid valve. A respective first sealing portion and respective second sealing portion are arranged circumferentially around a respective sealing opening of the base member. There is arranged at the inner side of the base member a first layer having a sliding friction coefficient which is less with respect to the valve body and/or static friction coefficient which is less than the base member, and which is at least partially in contact with the valve body during use of the seal.

摘要： The disclosure relates to a method and a device for checking the functionality of a crankcase ventilation system of an internal combustion engine. The crankcase ventilation system includes two crankcase ventilation lines arranged between a crankcase outlet of a crankcase and an associated introduction point into an air path of the internal combustion engine, via which crankcase ventilation lines gas can be introduced from the crankcase into the air path. The method includes measuring a pressure in the crankcase, supplying the measured pressure values to a control unit, and calculating the gradient of the measured pressure. The method also includes performing a gradient check, checking whether the gradient satisfies a specified criterion, and returning to the measurement of the pressure if the gradient satisfies the specified criterion. The method also includes recording an entry in a fault memory if the gradient does not satisfy the specified criterion.

摘要： Disclosed is an inductive position sensor including, on the one hand, a primary winding and, on the other hand, at least two secondary windings each having a plurality of turns formed of a succession of sides and produced on two opposite faces of a printed circuit board. Two pairs of two adjacent sides of each turn of at least one secondary winding form a first point directed toward a first longitudinal end and a second point directed toward a second longitudinal end of the printed circuit board, a projection on a plane of the printed circuit board of the two adjacent sides of each pair defining between them an acute projected angle.

摘要： A first and second substrate, and electrically conductive first and second connection parts are provided in a method for establishing an electrically conductive connection between two substrates. The first connection part is mounted on the first substrate by a first releasable connection and the second connection part is respectively mounted on the second substrate by a releasable connection. An electrically conductive connection assembly containing the first connection part and the second connection part is established by either a cohesive connection between a connection portion of the first connection part and a connection portion of the second connection part or an electrically conductive crossmember provided and a cohesive connection of a first length portion of the crossmember to the connection portion of the first connection part and a second cohesive connection of a second length portion of the crossmember to the connection portion of the second connection part being established.
