Patent number: 8751079Abstract: A method and a device are provided for controlling a battery pulse heating mode of a traction battery of a hybrid vehicle. The method includes detecting a traction battery temperature (T) upon start-up of the hybrid vehicle. The method then includes determining a dependency of fuel consumption (V) during a battery pulse heating mode on the distance (W) travelled for at least one predefined road type at the detected traction battery temperature (T). The method continues by displaying the determined dependency on a display device (50), using an input device (60) to select whether a battery pulse heating mode should be carried out; and controlling the battery pulse heating mode as a function of the selection.Type: GrantFiled: April 21, 2011Date of Patent: June 10, 2014Assignee: Dr. Ing. h.c.

Patent number: 8554399Abstract: A method is provided for operating a motor vehicle drive train having an internal combustion engine, an electric motor and an electrical energy storage. An actual charge state of the electrical energy storage is detected and compared with an established setpoint charge state to determine one of several operating modes for the drive train. The setpoint charge state is determined as a function of an instantaneous driving state of the motor vehicle so that conclusions can be drawn about imminent deceleration, imminent acceleration or imminent cruise control, instantaneous transmission data and/or instantaneous hybrid drive data. Range boundaries and/or range extents of operating modes are shifted as a function of the setpoint charge state.Type: GrantFiled: August 6, 2009Date of Patent: October 8, 2013Assignee: Dr. Ing. H.C.

Patent number: 8347840Abstract: A process for starting a direct-injecting internal-combustion engine is disclosed. The process includes triggering a separate drive for adjusting the camshaft for causing an angular position change between the crankshaft and the camshaft until the separate drive rotates the crankshaft such that a working medium is compressed by a piston in a cylinder of the internal-combustion engine. The position of the pistons of the internal-combustion engine is determined by using position determining devices to identify the cylinder of the internal-combustion engine in which the working medium is compressed. Fuel is injected into the cylinder in which the working medium is compressed when the cylinder is in a proximity of an upper dead center to start the internal-combustion engine.Type: GrantFiled: September 26, 2008Date of Patent: January 8, 2013Assignee: Dr. Ing. h.c.F.

Patent number: 8047959Abstract: A method is provided for starting a piston engine of a hybrid drive in an electric travel state. The hybrid drive includes at least the piston engine, an electric motor, a transmission, and a clutch situated between the piston engine and the electric motor. A converter lockup clutch, which is switchable into a slip state, is also provided. A slip is set at the converter lockup clutch, and a speed of the electric motor is then increased.

Patent number: 7654932Abstract: A method operates a drive train the is formed of an internal combustion engine, an electric motor, a transmission and a first clutch that connects the internal combustion engine to the electric motor. During an operating state for applying a current requested torque to a transmission input with the electric motor switched on and the internal combustion engine switched off, the internal combustion engine is connected into the circuit by increasing the torque applied to the drive train by the electric motor before the internal combustion engine starts, in such a way that only the current requested torque is applied to the transmission input. Excess torque is extracted from the drive train by actuating the first clutch and applying the excess torque to the internal combustion engine in order to accelerate it. The internal combustion engine is started when its starting state is reached.Type: GrantFiled: July 30, 2007Date of Patent: February 2, 2010Assignee: Dr. Ing. h.c. F.
