A method for controlling at least one first drive unit of a vehicle as a function of operating states of a second drive unit of the vehicle during a switchover operation. The first drive unit is associated with a first control unit and the second drive unit s associated with a second control unit. At least one message is transmitted to the first control unit by the second control unit. The message includes: a first desired value TQ1 of a controlled variable prior to the switchover operation; a second desired value TQ2 of the controlled variable after the switchover operation; and information on the angular position of a shaft of the second drive unit at the projected point of time of the switchover operation.

A method for controlling a hybrid drive of a vehicle includes detecting a traffic and/or street situation ahead of the vehicle, and based on the detected situation, determining an upcoming increase of a performance requirement to be expected from the hybrid drive and increasing a withdrawal rate of an electrical energy source of the hybrid drive. This increase occurs before the performance requirement is realized. The performance requirement may be realized according to the increase of the withdrawal rate, e.g., in conformity with a performance requirement which may be entered via an interface, for example an accelerator pedal.

A method for operating an internal combustion engine is disclosed, in which method test injections are carried out in order to adapt, during the operation of the internal combustion engine, the injection parameters used for the control of the injection processes. For this purpose, during the test injections, an electric machine which is coupled to the internal combustion engine generates negative torque impulses in a manner synchronized with the positive torque impulses generated by the test injections, which negative torque impulses counteract the torque impulses generated by the test injections. In this way, rotational speed oscillations generated by the test injections are eliminated. Also described is an internal combustion engine of said type.

A method for operating a hybrid vehicle and a hybrid vehicle are disclosed. The hybrid vehicle includes a supercharged internal combustion engine having an overboost function and at least one electric drive. An overboost phase of the supercharger of the internal combustion engine is followed by a regeneration phase of the supercharger and a corresponding drop in torque, wherein the at least one electric drive is used to at least partially compensate for the drop in torque of the internal combustion engine during the overboost regeneration phase of the supercharger. Thus, an improved driving behavior with an extended overboost phase can be achieved.

An engine-controlling unit/method for an internal-combustion engine with first and second combustion-chamber groups having a first and second catalytic exhaust-gas converter, respectively, having (a) a master control device that controls a combustion-air ratio for the first combustion-chamber group by forcibly exciting the first combustion-chamber group, further having (b) a slave control device that controls a combustion-air ratio for the second combustion-chamber group by forcibly exciting the second combustion-chamber group, and further having (c) a data link between the master and slave for control through the master. It is proposed (d) for the master to transmit a synchronizing signal to the slave over the data link during changeover between the rich and lean combustion-air ratio within the scope of forced excitation, and (e) on receipt of the synchronizing signal from the master for the slave to change over within the scope of forced excitation between the rich and lean combustion-air ratio.

Engine-controlling unit and engine-controlling method for an internal-combustion engine

An internal combustion engine has a plurality of cylinders having combustion chambers and each being associated with a spark plug designed for igniting a mixture of air and fuel in the combustion chamber, and at least two adjusting devices for adjusting the air supply to the combustion chambers of the different cylinders. To control the internal combustion engine, an individual ignition angle is detected for each group of cylinders to which the same air mass per working cycle is respectively supplied and during the respective working cycles of which the same loss torque is decisive. The decisive loss torque is the one associated with the cylinder that is in its intake cycle during the respective working cycle of the respective cylinder of the respective group. The individual ignition angle for each group is detected as a function of the decisive loss torque for the respective group.

An engine control system comprises a first control device which is associated with a first section of the cylinders, and a second control device which is associated with a second section of the cylinders. The first control device is designed in order to determine an intermediate required value (TQI_INT_SP_FAST) for a torque to be set quickly which is set by way of one or more final control elements for setting a quantity of fuel that is to be metered or an ignition angle. The intermediate required value (TQI_INT_SP_FAST) is determined depending on at least one operating variable of the internal combustion engine. The first control device is also designed in order to determine at least one correction value for the torque to be set quickly [lacuna] at least one operating variable.

In a method for implementation of a fault diagnostic system having a number of diagnostic modules and in an in-vehicle fault diagnostic system, a second diagnostic module whose diagnostic result depends on the result of the fault diagnosis of at least one first diagnostic module begins its diagnostic cycle without waiting for the diagnostic result of the first diagnostic module. The second diagnostic module writes its diagnostic result into a secondary fault memory. When the first diagnostic module has ended its diagnostic cycle without finding a fault, the diagnostic result of the second diagnostic module is transferred from the secondary fault memory into a primary fault memory.
