In a method for operating a motor vehicle, an actuation speed of a power input element, e.g., an accelerator pedal, is detected and evaluated, and a drag torque is influenced as a function of the detected actuation variable. At least one measure which influences the drag torque is carried out if the following conditions are all satisfied: (i) an actuation speed is less than a limiting value, (ii) a position of the input element is greater than zero, and (iii) the power input element is actuated in the direction of a power reduction.

Method for operating a motor vehicle

To reduce the space of a control device having a power circuit and an electronic component, the power circuit including components to which higher currents are applied, in particular currents in the range of 5 A to 70 A, and the electronic component including a switching logic realized on a circuit board, the electrical connections between the components of the power circuit are realized by a single-layer pressed screen. Receptacles for the contact pins of the components are formed in the pressed screen. The receptacles are arranged and formed in such a way that the components are held in frictional engagement in the receptacles and are electrically contacted via the contact pins.

The electrically conducting cable for making an electrical connection between consumers and a voltage supply device (,) has a single conductor made of electrically conductive material and a common plug (,) at one end of the single conductor for connection to a common voltage supply device (,). The single conductor is subdivided into respective regions (A,B,C) of different cross-sections, which become progressively smaller in a direction along the single conductor from the plug (,) toward the consumers (,). Each region is connected to at least one consumer at a branch point at the end of the region, advantageously via an overload-protected semiconductor switch, so that all the consumers are supplied via the single conductor.

Electronic circuit for supplying a voltage

It is known for a central electronic control unit in a motor vehicle to exchange data through a serial data bus with other control units, e.g. those for fuel injection, ignition timing, and braking. Prior art systems transmitted these data automatically, regardless of whether all these parameters were relevant to the actual operating state of the vehicle, thereby resulting in heavy loading of the serial bus. The present invention determines which parameters are irrelevant to the current operating state and suppresses transmission, or even calculation, of these irrelevant parameters.
