An electrical drive unit for a vehicle includes a number of structurally independently designed electrical machines. In each of the electrical machines there is a machine output shaft configured to provide a machine torque, and in each of the electrical machines there is inserted in a receiving region assigned to it and is connected to the receiving unit. The number of the inserted electrical machines is predetermined as a function of a specified value, which is prespecified in advance for an output-side characteristic quantity of the drive unit to be constructed. The number of the inserted electrical machines is between 1 and a maximum number. The electrical drive unit also includes a common main shaft, via which the drive unit is configured to provide a drive unit torque on the output side, and a coupling element, via which the machine output shafts are operationally connected on the driving side to the main shaft to input the machine torques.

Electrical drive unit for a vehicle

A system and method for active noise compensation in a vehicle is provided. The system has at least one apparatus for detecting a noise, a computer unit for calculating a compensation sound, at least one apparatus for generating a compensation sound which interferes with the noise, and a device for detecting at least one driver-specific parameter. The compensation sound is calculated depending on the at least one driver-specific parameter. Also provided is a motorcycle having a system for active noise compensation.
