Abstract: A method and a system for detection of torque deviations of an engine (101) in a vehicle (100). A measurement (201) is made of actual measured values Dact related to a behavior of at least one parameter which is related to an actual torque Meng_act delivered by the engine (101). This actual torque Meng_act is delivered here by the engine (101) in consequence of a torque Meng_req demanded from the engine (101). A comparison (202) is then made of the actual measured values Dact which are related to the behavior of the at least one parameter with previously determined measured values Dref of correspondingly at least one respective parameter related to the actual torque Meng_act. The previously determined measured values Dref will here have been determined during normal operation of the vehicle (100). Detection is then made of whether the actual measured actual torque Meng_act deviates from the demanded torque Mengj-eq. The detection is based here on the comparison of the actual measured values Dact with the previously determined measured values Dref.

Abstract: A communication bus (B1, B2, Bp) in a motor vehicle (110) transfers electrical signals between the nodes (N1, N2, N3, Nn, N21, N2m, Np1, Npr) included in the motor vehicle. The communication bus comprises two unshielded signal lines (S1, S2) and a decoupling line (D), which are configured so as to divert undesired electromagnetic radiation deriving both from external systems that are not connected to the communication bus (B1, B2, Bp) and the electrical signals transferred via the unshielded signal lines (S1, S2). The decoupling line (D) is connected for alternating current to a ground potential in one and only one (N3) of the nodes (N1, N2, N3, Nn, N21, N2m, Np1, Npr) included in the communication system.

Abstract: A drive system for a vehicle comprises two electrical machines arranged between a combustion engine and an input shaft to a gearbox. The first machine rotor is connected with a planetary gear component, and the input shaft of the gearbox with another planetary gear component. The second machine rotor is connected with the output shaft of the combustion engine, which is also connected with another planetary gear component. A first locking means movable between a locked position, wherein the planetary gear's three components rotate at the same rotational speed, and a release position, wherein the components rotate at different rotational speeds. A second locking means movable between a locked position, and a release position wherein the combustion engine's output shaft is locked to a stationary element in the locked position and disconnected in the release position to rotate with the second machine rotor and a planetary gear component.

Abstract: Disclosed is a system for regulation of torque demanded from a prime mover of a vehicle, which prime mover responds to the torque demanded by delivering a dynamic torque. This dynamic torque is related by a gear ratio to a dynamic wheel torque which a power train comprising the prime mover imparts to at least one tractive wheel of the vehicle. The system regulates the torque demanded in such a way that a difference between the torque demanded and the dynamic torque is actively limited by employing feedback of the dynamic torque at an earlier time. The torque demanded at a time (t) for the regulation is limited to a maximum value which exceeds the dynamic torque at an earlier time by an offset value. The torque demanded is continuously varied according to the dynamic torque, so that power train oscillations in the vehicle are reduced in number and/or magnitude.
