摘要： The invention relates to a method for switching an engine of a vehicle on and off, which comprises a braking device having one or more braking circuits. The engine is switched off (S4) as a function of a first signal that is independent of a preliminary pressure (p
pre ) in the braking circuit(s), when the vehicle is at standstill, or the vehicle speed (v) is less than a predetermined speed threshold value (v
threshold ), and the engine is switched on (S6) as a function of the first signal or of a second signal that is independent of the preliminary pressure (p
pre ).

摘要： The invention relates to a method which enables a control unit to have time-flexible access to measurement data of individual sensors. The control unit (SG) sends a request telegram to the sensors (S1, ..., S5) and, upon comparing the request telegram with its own address, each sensor (S1,..., S5) determines whether and at what time interval (ZS0,..., ZS4) it should transmit the measurement data thereof to the control unit (SG).

摘要： The invention relates to a method for stopping an internal combustion engine, wherein the amount of air which is supplied via an air metering device of the internal combustion engine, in particular a throttle flap, is reduced once an engine stop request has been registered. The amount of air which is supplied via the air metering device of the internal combustion engine is again increased when the detected speed of the internal combustion engine falls below a predefinable speed threshold value, wherein the predefinable speed threshold value is increased when, after an increase of the measured amount of air, an intake cylinder does no longer pass through a lower dead centre until the standstill of the internal combustion engine.

摘要： In a method and an apparatus for detecting a continuous ingress of fuel into the lubricating oil of an internal combustion engine, that is to say oil dilution, in particular of a motor vehicle during cold starting, there is provision, in particular, for the continuous ingress of fuel to be detected (205) by means of a lambda control. The continuous ingress of fuel is preferably determined using the outgassing of fuel from a crankcase of the internal combustion engine, wherein the depletion is based on adaptation values of the lambda control (210).

摘要： The invention relates to a method for starting an internal combustion engine, in which at least one function (T, T1, T2) is started by a control unit at a certain crankshaft angle, wherein the function is displaced by a relative angle (ΔKW) to a later crankshaft angle from the start of the internal combustion engine until an end condition is reached.

摘要： An internal combustion engine (10) is operated with direct fuel injection into the combustion chambers (12). Furthermore, the internal combustion engine is operated with sub-optimum ignition angle efficiency and an apportionment of a fuel quantity, which is to be injected before the start of a combustion, into at least two partial injections (ti_1, ti_2). A torque loss which results from the sub-optimum ignition angle efficiency and/or from the apportionment of the fuel to be injected is compensated by means of an increased charge of the combustion chambers (12). The fuel quantity and the charge are coordinated with one another in such a way that the air ratio lambda (L) of the combustion chamber charges is greater than 1. The method is characterized in that a measure for a temperature (T) of the catalytic converter (28, 30), in particular a measure for the temperature (T) at the inlet of the catalytic converter (28, 30), is determined and in that a quantity of reducing exhaust-gas constituents is increased by means of at least one intervention into the control of the internal combustion engine (10) if the measure for the temperature (T) exceeds a predetermined temperature threshold value (T_S). The approach according to the invention permits rapid heating of the catalytic converter (28, 30), wherein the hydrocarbon emissions when the catalytic converter (28, 30) is cold are at the same time as low as possible.

摘要： The invention concerns a method and a device for operating an internal combustion engine injection device (5), said injection device (5) comprising injection valves (40) via which the fuel is injected directly into the combustion chamber (100) of the internal combustion engine, and members for detecting irregularities (310), as well as members for determining a fuel pressure (320). A mechanical breakdown of an injection valve (40) is detected, when the irregularity is located on one cylinder and causes a drop of fuel pressure within a threshold value (SW). An electrical breakdown of the injection device (5) is identified, when the irregularities of the cylinders (110), which are associated with the final stage of the injection device (5), are observed and the pressure has dropped below a threshold value (SW) based on the identified breakdowns, different responses to breakdowns are introduced.
