Abstract: A method for controlling a hybrid vehicle having at least two propulsion engines. According to the specification of an operating controller, propulsion is provided via the first propulsion engine, in particular an internal combustion engine, and/or the second propulsion engine, in particular an electric motor. The percentage contribution of the propulsion of the second propulsion engine is controlled as a function of the data pertaining to the travel route communicated to the operating controller, taking into account a charge state of an energy accumulator. An optimized operating strategy is determined by specifying a geographic destination and/or a destination parameter of the operating strategy, the travel route being selected by taking into account the optimized operating strategy when alternate travel routes are available.

Abstract: A method for improving the performance of a traction battery during a driving start phase of an electric vehicle. A driving start point in time at which the driving start phase begins is provided. A temperature of the traction battery is detected. This temperature is compared with a minimum operating temperature, and the traction battery is heated if the comparison reveals that the temperature of the traction battery is below the minimum operating temperature. The heating takes place with a temperature increase which provides a temperature of the traction battery at the driving start point in time, which is no lower than the minimum operating temperature.

Abstract: Provided is a method for charging a battery that dynamizes the charging phase of the battery, thereby enabling optimum charging. The dynamization of the charging phase is intended to achieve effective mixing of the battery acid and/or depolarization of the electrodes and ultimately result in improved receiving of the charging current. In this context, the charging method can be carried out according to at least two different methods. In a first method, targeted discharges result in depolarization of the electrodes due to locally decreasing acid density, and in a second method the battery acid is reliably mixed as a result of temporary increasing of the charging voltage via the so-called gassing voltage of the battery. Both methods result in improved battery charging. In an embodiment of the method, the two methods are combined.

Abstract: A battery state detection arrangement is provided for use in conjunction with a series connection of multiple battery cells, e.g., a series connection of at least two lead batteries in a vehicle electric system having a voltage which is higher than conventional system voltages. The battery state detection arrangement detects both a defect in a battery and a defect in the overall system and transmits signals to a higher-level energy management system as well as, if necessary, a display. Additional components provide a charge equalization in the batteries by selectively recharging or selectively discharging unevenly charged batteries.

Abstract: The method for displaying speed variables in a motor vehicle includes automatically selecting and displaying one of a number of different possible speed scales on a speedometer according to the physical units for speed values employed at the current location of the vehicle. An acoustic and/or optical alarm signal is produced when the vehicle passes from one governmental region in which one set of physical units is used to another in which a different set is used. In addition, speed limits at the current location may be displayed on the speed scale itself by highlighting an appropriate scale mark or producing a scale mark of a different length or color. The current location may be obtained from an on-board GPS. The speed limits and physical units for speed values at the current location are retrieved from a data storage media according to that location. The speed limits may be updated by radio connection. Digital display devices for speed values with similar features are disclosed.

Abstract: A telematic device in which a car radio with an RDS module, a wireless telephone, and a positioning and navigation system are provided in one housing. The housing is designed so that it can be installed in a standard bay in the instrument panel of a motor vehicle. The telematic device can be used to receive general information via the car radio as well as specific information via the GSM module. In addition, data relating to, for example, the vehicle position, a desired destination, or an emergency call can be sent to the central station. The central station calculates one or more routes and transmits them back to the telematic device. In the event of an accident or a vehicle breakdown, an emergency call is transmitted and assistance obtained. Additional telematic services provided include an expanded anti-theft system for the motor vehicle, hotel reservations, etc.
