The invention relates to a method for transmitting vehicle data in the form of kilometer readings of a motor vehicle (1) to a memory element (7) having a counter, which memory element is removable from the motor vehicle. At time intervals, the kilometer reading of the motor vehicle is transmitted to the memory element (7), and after each kilometer reading transmission, the difference between the last transmitted and the newly transmitted kilometer reading is added up in the counter.

The switched state of a pressure switch in a tank ventilation system of a motor vehicle is used for testing the function of the tank ventilation system, the pressure switch being in a low-pressure position if the pressure in the tank ventilation system is lower than a predefined pressure limit while being in a high-pressure position if that is not the case. A defective pressure switch can result in wrong assessments. Disclosed is a method for testing the function of the pressure switch, the method encompassing the following steps: a switched state of the pressure switch is detected; a measure is carried out that increases the pressure in the tank ventilation system above the pressure limit if the pressure switch is in the low-pressure position; a defect of the pressure switch is identified if the pressure switch remains in the low-pressure position after carrying out the measure.
摘要:
A device for the detection of the characteristics of an impact into a motor vehicle includes at least one signal generating unit for generating a defined acoustic impulse sequence depending on the speed of the impact, particularly a structure-borne acoustic impulse sequence due to a deformation of a chassis component of the motor vehicle. The acoustic impulse sequence is generated by way of a mechanical activation of the signal generating device caused by the deformation. A sensor system is disposed to detect the defined acoustic impulse sequence. An analysis unit analyses the signals supplied by the sensor system such that information can be supplied on the characteristics of the impact.
摘要:
The hub and spoked of a steering wheel consist of a synthetic thermoplastic resin and just as the rim are covered with a layer of a deformable plastic. To provide a steering wheel which is light in weight and has a high temperature stability, the hub and spokes consist of a polyamide which has been modified with elastomers and fibers.

The invention relates to a rechargeable battery (1) comprising at least one storage module for electrical energy and at least one cooling device (2) for cooling or controlling the temperature of the at least one storage module, wherein the cooling device (2) has a single-layer or multilayer film (4, 9) and is lying with this film (4, 9) against the at least one storage module. The cooling device is provided with at least one stiffening element (19).
摘要:
An exhaust-gas cleaning system includes a nitrogen oxide reduction catalytic converter for reducing nitrogen oxides which are contained in the exhaust gas. A reducing agent is introduced into the exhaust-gas flow and is in the form of a vapor. A reducing-agent metering device for the metered addition of the reducing agent or a reducing-agent precursor to the exhaust-gas flow includes a vaporizer, which is arranged in the exhaust system upstream of the nitrogen oxide reduction catalytic converter. As a heat source, the vaporizer has (1) a heatable deflector surface, onto which the reducing agent, which is supplied by a feed unit, is directed under pressure; or (2) a microwave generator.
摘要:
A rotor for an electric machine including a rotor shaft and a core stack fastened thereto, at least one coolant outlet being provided at the axial end-face side of the core stack. For centrifugal cooling of the winding heads of the stator of the electric machine, a coolant conducting structure is provided at the axial core stack end-face side, via which the coolant exiting from the coolant outlet is spun off radially outwardly in the direction of the winding heads as the result of centrifugal force. The coolant conducting structure is designed as a single-material and/or one-piece integral part of the rotor, in particular the rotor core stack.
摘要:
A drive device for a vehicle, including an electric machine having a stator housing, on whose outer circumference a pulse width modulated inverter housing is formed, in which a pulse width modulated inverter having at least one pulse width modulated inverter contact is arranged, which is connected to a stator contact via a contact bridge, an AC filter being assigned to the contact bridge to reduce common mode flows and/or for the purpose of EMC shielding. According to the invention, the AC filter is a component separate from the pulse width modulated inverter and may be mounted in the pulse width modulated inverter housing independently of the pulse width modulated inverter.
