- the invention relates to an electronic control device according to the genus of the main claim. Let such electronic control devices use themselves to solve a variety of tasks. An action, especially a tax function, is depending on the meter reading of a meter carried out. This action can then, for example when the counter counts or when it counts has reached a certain counter reading.
- the counter is connected to a clock source that the counter specifies the counting clock.
- the area of application of the known electronic control devices is due limited relatively rigidly specified possibilities.

With the injection control is dependent the crankshaft angle and other parameters the start of injection and the duration of injection to realize.
- the counter first register in which a first, specifiable, in particular changeable register value can be registered by means of a charging device to set as the current counter reading Counter can be fed and the loading device an event device is assigned which is dependent the predeterminable occurrence of an event the setting of the Triggers by starting the charging device
- the functions mentioned can be optimally implemented.
- the injection duration depending on the in the first register of the registered register value the injection duration can be adjusted accordingly.
- the Injection takes place with the start of the counter and ends when it reaches a certain counter reading Has.
- the counter is only started then when the event facility is dependent the predeterminable occurrence of an event Set the counter by starting the charging device triggers.
- the first register value of the first register by means of the Charger supplied to the meter, which then with a counter reading corresponding to the register value starts.
- the time of injection determine. Because an influence insists on the occurrence of the event and also the register value and thus the counting time of the Counter can be varied - can be mentioned in the Automotive injection control example injection timing and injection duration the constantly changing Operating conditions when driving a Be adapted to the vehicle.
- the event facility points at least one comparator, the one second, predeterminable, in particular changeable register value a second register with the value of a Clock facility compares, and that entry of the event due to the identity of the second register value with the value of the clock device he follows.
- the clock device can for example go through periodic clock cycles, so that whenever the second register value is identical to the data of a specific cycle cycle is the comparator determines this equality and thus triggers the event signal. Since the second register value is changeable Take current conditions into account.
