A method for operating a mobile radio module of a telephony controller for a means of transport includes receiving a predefined deactivation command using the telephony controller via a wireless interface. In response thereto, the method also includes deactivating the mobile radio module.

Telephony control device, means of locomotion and method for operating a mobile radio module for a means of locomotion

A method for resource management in a vehicle-based mobile communications unit. In the method, during a mobile communication transaction conducted via two simultaneously established mobile communication channels, the user-nonspecific data components of the currently active identity profile are compared with one another to determine the mobile communication services provider currently being used. In case of a mobile communication services provider identity determined within the context of the comparison, one of the mobile communication channels is switched off and the mobile communications are conducted via the other mobile communication channel.

Method for resource management in a vehicle-based mobile communications unit

A method for providing aid after a vehicle accident involving a vehicle includes establishing a wireless connection between the vehicle and a rescue center. First sensor data, which is ascertained via a first sensor in the vehicle, is transmitted to the rescue center, while second sensor data, detected by the first sensor and/or by a second sensor of the vehicle, is transmitted to and stored at a data storage unit independent of the rescue center. Contact information assigned to the data storage unit is transmitted from the vehicle to the rescue center via the wireless connection. The second sensor data and/or data derived therefrom stored in the data storage unit is retrieved by the rescue center using the contact information, where the retrieved data is usable to select aid appropriate to a type of the vehicle accident.

Providing an aid means after a vehicle accident

A communication system is provided for a vehicle having multiple antennas and multiple transmitting and/or receiving interfaces. At least one first antenna is arranged in the interior of the vehicle, and at least one second antenna is arranged on the outside of the vehicle. The first antenna is designed to wirelessly establish at least one part of a data connection between a first communication unit which is located in the interior of the vehicle and at least one first network base unit which is located outside of the vehicle via a first transmitting and/or receiving interface. The second antenna is designed to wirelessly establish at least one part of a data connection between a second communication unit which is located in the interior of the vehicle and the first and/or a second network base unit which is located outside of the vehicle via a second transmitting and/or receiving interface. The communication system is designed such that a data connection can be established within the vehicle between the second communication unit and the first antenna via the second transmitting and/or receiving interface.

Vehicle communication system and method for operating such a system

An energy storage device is provided including multiple back-to-back-disposed storage cells, from the first end of which the plus pole is made to emerge and from the other end of which the minus pole is made to emerge, thereby creating a series circuit of the storage cells. In order to reduce fabrication costs, it is proposed that each of the storage cells have a continuous opening between the plus pole and the minus pole, through which opening a guide rod extends that secures the back-to-back-disposed storage cells in this position.

Energy store with guide rod

A motor vehicle (KFZ) including an electric power source (EQ) for providing DC current, a converter (U) for converting the DC current into three-phase AC current of identical phase angle or polyphase current as a function of the vehicle operating state, and an electric machine (EM), to which the current provided by the converter is fed, is provided.

Motor Vehicle

A drive system for a motor vehicle comprising an internal-combustion engine, an electric machine coupled to the internal-combustion engine, and a transmission device through which a ratio change can be implemented without a tractive power interruption is described. Also described is a control device for controlling the electric machine and for controlling the transmission device. The control device is constructed such that, in the event of a braking demand, the demanded total braking torque is at least proportionally provided by the electric machine, and, in the case of an existing braking demand with a constant total braking torque and a change of the transmission ratio implemented in the presence of this braking demand, the electric machine is controlled such that the total braking torque changing because of the ratio change is at least partially compensated, so that a constant total braking torque according to the braking demand is maintained.

Drive system for a motor vehicle

Hybrid drive for a motor vehicle with a drive train, comprising a combustion engine and a vehicle transmission with variable gear ratio and a first and second electrical machine which can be operated both as a motor and a generator, each of which comprises a stator and a rotor with the second electrical machine being in a permanent nonpositive connection with an input of the vehicle transmission, with a shiftable clutch each being arranged between the electrical machines and the drive shaft of the combustion engine, and with the electrical machines to be connected with each other and/or an electrical energy source via an electronic control circuit. The two electrical machines are to be arranged in a common housing, and one of the stators of the electrical machines together with the electronic control circuit and/or the other stator is accommodated on a common carrier.

Hybrid driving system for a motor vehicle

A method for controlling and regulating the input power distribution of prime movers in a power train () of a motor vehicle which has one internal combustion engine (), at least one electric machine (), at least one clutch (), the same as one transmission (), and in which there is at least one control and regulation unit which, on the basis of predetermined, measuring and calculated values, controls and regulates the input power distribution between the internal combustion engine () and at least one electric machine () with regard to power dynamics of the vehicle, the same as its energy consumption, its emission and its driving comfort. In addition, departing from a signalized input power wish, it is provided that existing nominal operating values for the operation of at least one electric machine () is changed to new nominal operating values adapted to the actual input power wish and to changed operating situations of the vehicle and, that to determine the new nominal operating values for at least one electric machine (), the future maximum and minimum torques and outputs are precalculated, the same as the efficiency degree or losses thereof.

Method for control of input power distribution in a motor vehicle with hybrid engine drive

A hybrid drive for a motor vehicle which possesses, in a gear train ( ), a first electrical machine ( ) located between an internal combustion motor ( ) and a multi-gear vehicle transmission ( ). The hybrid drive further possesses a second electrical machine ( ) permanently connected with an input shaft ( ) of the transmission. First and second clutches ( ), respectively, are placed between the first and second electrical machines ( ) and the internal combustion motor ( ) and the first and second electrical machines ( ) can be respectively driven as either a motor or a generator.
