Claims15
A drive and deceleration unit, comprising:
- a mechanical brake;
- and
- an e-drive, wherein
- the mechanical brake and the e-drive are provided as a unit for acting on a single wheel connection,
- the e-drive in generator mode exclusively brakes when a braking action corresponding to the brake request is achievable thereby, and
- the mechanical brake additionally brakes when the braking action corresponding to the brake request cannot be achieved by the e-drive alone.
3 more elements
