A circuit for power supply of a ventilation fan for cooling the interior of a motor vehicle and/or a motor vehicle battery by means of solar cells, with a manually actuated switch for switching the solar cell power supply to the ventilation fan or battery. An automatic control provides a fully automatic mode for automatic switching of the solar cell power supply depending on the temperature in the motor vehicle interior and/or the battery charging state which can be overridden by activating an actuating element of a manually activated switch in a semiautomatic mode. Furthermore, there is an optical display for indicating which of the automatic and semiautomatic mode is activated.

Circuit for power supply of a ventilation fan and a battery by means of solar cells in a motor vehicle

Solar roof for motor vehicles with a solar generator having solar cells for supplying power to a power consumer and/or a battery and with a D.C. converter for impedance matching between the solar generator and the consumer and/or battery. The D.C. converter is a flat module and is integrated into the solar cell carrying roof panel.

Actuating means for a motor vehicle locking brake

A process for ventilating the interior of a motor vehicle having a closure which can be opened by a drive motor, an interior temperature-setpoint value generator, at least one interior temperature sensor, at least one outside temperature sensor and a logic component with inputs, outputs and a computer portion. Existing components (sensors, logic components) of different units are used and operatively linked so that the driver is largely relieved of the need to manipulate numerous controls.

Process for ventilating the interior of a motor vehicle and ventilation

A process for cooling the interior of a motor vehicle and a roof system for its performance which has a roof part that can be opened by an electric motor. As a function of the interior temperature and an interior setpoint temperature, an automatic moving of the roof part that can be opened into a first open position takes place, in which a large roof opening is created. Time-dependent or as an alternative to this, when the temperature is less than a lower threshold temperature, an automatic moving of the roof part that can be opened into a second open position takes place, in which a smaller roof opening is created. The process and roof system enable quick removal of a build-up of heat when getting in the vehicle and in the beginning phase of a drive.
