Patent number: 9748795Abstract: An electric vehicle includes an electric machine, a generator generating a first AC output current, an internal combustion engine driving the generator, and a first electric plug-in charging device. When the engine is started, the generator supplies the battery with charging power. The first plug-in charging device is geometrically configured to be connectable with single phase AC power mains to supply the battery with charging power in a vehicle deactivated state. The first plug-in charging device is configured for a maximum electric power voltage load of 240 volts and a maximum current strength of 32 amperes. A second electric plug-in charging device is integrated into the vehicle. A DC charging station is connectable to the second charging device in the deactivated state so the DC charging station is usable either exclusively or simultaneously with the single phase AC power mains for charging the battery.Type: GrantFiled: March 1, 2013Date of Patent: August 29, 2017Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Merten Jung, Patrick Mueller, Robert Griessbach, Thomas Schimanek, Christian Hieber

Patent number: 6806590Abstract: A data bus arrangement for a plurality of nodes connected to each other including a logical decision gate having a plurality of inputs corresponding to the number of nodes. A converter module is connected between each node and the logical decision gate. Each convertor module converts an optical output from one of the nodes to an electrical signal which is fed to one of the inputs of the logical decision gate. A separate switch is connected between an output of the logical decision gate and an input of each one of said convertor modules for controlling the convertor module independent of an output signal on the output of the decision gate.Type: GrantFiled: November 21, 2000Date of Patent: October 19, 2004Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Karel Smuk, Robert Griessbach, Martin Peller, Josef Berwanger

Patent number: 6744985Abstract: A data bus structure for cooperating with a plurality of nodes which are connected to each other. The data bus structure includes optical transmission modules associated with each node and a logical decision gate having inputs associated with each node. The logical decision output signal is provided in parallel to each node through the optical transmission modules. These modules serve to convert optical signals from the nodes to electrical signals and output to the logical decision gate and to convert electrical signals output from the logical decision gate to optical signals and output to the nodes. In order to separate a single node from the data bus, the transmission mode is monitored and an independently controlled switch is positioned between the logical decision gate and the optical transmission module. This arrangement functions to exclude a node from bus communication while leaving the remaining nodes uninterrupted.Type: GrantFiled: November 16, 2000Date of Patent: June 1, 2004Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Karel Smuk, Robert Griessbach, Martin Peller, Josef Berwanger

Patent number: 6691549Abstract: A rollover sensor for a vehicle continuously determines the inclination of a vehicle in at least one axis. In order to cancel drift deviations in the sensor, the inclination is average in the at least one axis, continuously along a defined route. The formed average value is assumed as the zero position. Inclination of the vehicle due to inclination of the road surface is compensated based on variations in ambient air pressure indicative of changes in altitude.Type: GrantFiled: January 8, 2001Date of Patent: February 17, 2004Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Joachim Froeschl, Robert Griessbach
