Patent number: 8651998Abstract: A method is for controlling a hybrid drive of a vehicle, which includes at least one internal combustion engine and at least one electric machine, having a first clutch situated between the electric machine and the drive train of the vehicle and a second clutch situated between the electric machine and the internal combustion engine. In the method, a predefinable clutch torque is applied to the second clutch for a start of the internal combustion engine by the operating electric machine, the rotational speed of the internal combustion engine is monitored, and the clutch torque is incremented to a higher value if the rotational speed of the internal combustion engine is less than a predefinable threshold value within a predefinable time interval.Type: GrantFiled: August 14, 2007Date of Patent: February 18, 2014Assignee: Robert Bosch GmbHInventors: Rene Schenk, Oliver Kaefer, Thorsten Juenemann

Patent number: 8612080Abstract: A hybrid drive (52) of a motor vehicle (50). In the motor vehicle (50), an electric motor (58) acts as the driving force on a first axle (54) and an internal combustion engine (60) as a driving force on a second axle (56). In an operation, in which only the electric motor (58) acts on the first axle (54), a check is made to determine whether the internal combustion engine (60) is to be started to drive the second axle (56), wherein a first set of conditions for a road start, taking into account first criteria, and a second set of conditions for a starter motor start, taking into account second criteria, are defined and checks are made independently of one another to determine whether the first set of conditions for a road start or the second set of conditions for a starter motor start has been met.Type: GrantFiled: December 19, 2011Date of Patent: December 17, 2013Assignee: Robert Bosch GmbHInventors: Frank Steuernagel, Peter Deuble, Sascha Dreschmann, Manfred Hellmann, Thorsten Juenemann

Patent number: 8169173Abstract: A method for controlling a vehicle drive unit, the vehicle drive unit having at least two individual motors. A total actual torque is continuously compared with an allowable total torque, the total actual torque being calculated from individual actual torque values of the at least two individual motors, and the allowable total torque being calculated from the allowable individual torque values of the at least two individual motors, and an error response being initiated if the comparison establishes that the total actual torque is greater than the allowable total torque.Type: GrantFiled: August 4, 2006Date of Patent: May 1, 2012Assignee: Robert Bosch GmbHInventors: Bernd Doerr, Holger Niemann, Thorsten Juenemann, Per Hagman

Patent number: 8074527Abstract: The invention relates to a method for the continuous torque monitoring of a hybrid drive composed of an internal combustion engine with an engine control unit and an inherently safe electric drive with a control unit, wherein a permissible total torque is compared with the sum of an actual torque of the electric drive and an actual torque of the internal combustion engine. If the permissible total torque is reduced by the actual torque of the electric motor and is formed by a permissible torque of the internal combustion engine, it is largely possible by means of this method for existing software to be utilized further, and said software need not be amended. In the engine controller, it is largely possible for calculations to be carried out with torques which are normalized to the maximum torque of the internal combustion engine.Type: GrantFiled: January 30, 2007Date of Patent: December 13, 2011Assignee: Robert Bosch GmbHInventors: Holger Niemann, Thorsten Juenemann
