Abstract: A method and an apparatus for forming a fuel-air mixture for an internal combustion engine during a cold-starting and warmup phase. During the normal operation of the engine, fuel is evaporated by means of an evaporation and condensation system in order to recover low-boiling fuel components from the fuel delivered to first fuel delivery means during normal operation. The low-boiling fuel components condense and are collected as cold-starting fuel in a supply container. The engine, during the cold-starting and warmup phase, is supplied with cold-starting fuel from the supply container by means of second fuel delivery means, in order to reduce the concentration of hydrocarbons in the exhaust gas during the cold-starting and warmup phase.

Abstract: A method for terminating a braking intervention of an adaptive cruise control system of a motor vehicle. The braking intervention is terminated in accordance with a predefined algorithm in response to the driver overriding of the adaptive cruise control system. In this context, the algorithm is formed in such a manner that a jerk-free transition from braking to acceleration of the motor vehicle is ensured, thus increasing the ride comfort. The transition from braking to acceleration preferably takes place in accordance with a linear function. Provision can also be made for stepwise functions. To prevent the braking operation from being terminated prematurely by an inadvertent actuation of the accelerator, provision is made for a threshold value to be adjusted for the accelerator for a desire of the driver to accelerate. This threshold value is dependent on the deceleration during braking.

Abstract: The invention is directed to a method and an arrangement for synchronizing at least two power-adjusting elements of an internal combustion engine which are electrically driven independently of each other. For carrying out the synchronization, the intervals between the respective combustions or the corresponding segment times of at least two cylinders are detected to which individual power-adjusting elements are allocated and their deviation is determined. At least one power-adjusting element is adjusted in order to maintain this deviation within a pregiven tolerance band. A correction of the control of the power-adjusting elements is derived in dependence upon the adjustment. The power-adjusting elements are adjusted in mutually opposite directions.
