  • Coefficient-of-friction estimator
    Patent number: 11027712
    Abstract: A method for determining a coefficient-of-friction, the method including braking a first wheel of a vehicle such that a slip between the first wheel and a roadway is less than a slip between a second wheel of the vehicle and the roadway, and determining a coefficient-of-friction between the first wheel and the roadway based on the behavior of the first wheel during the braking. The method optionally including hazard braking the vehicle.
    Type: Grant
    Filed: May 16, 2017
    Date of Patent: June 8, 2021

  • Drive train of a motor vehicle having an internal combustion engine and a starter generator
    Patent number: 9074656
    Abstract: A drive train (1) of a motor vehicle has an internal combustion engine (2) with a crankshaft (6). A transmission (3) is connected downstream of the internal combustion engine (2) to drive at least one axle (5) of the motor vehicle. A starter generator (23) is assigned to the internal combustion engine (2). The starter generator (23) is attached to the crankshaft (6) by two separate drive trains (13, 22; 24, 25). One (24, 25) of the drive trains (13, 22; 24; 25) has a shiftable clutch (29) and the other (13, 22) of the drive trains (13, 22; 24, 25) has a shiftable clutch (32) or a freewheel (11) that is active during a starter mode of the starter generator (23). The drive train ensures an optimum start capability of the cold internal combustion engine and additionally permits electric boosting of the internal combustion engine.
