|
||||
* @section sec_main Brief overview
|
||||
*
|
||||
* rusEfi runs on crankshaft or camshaft ('trigger') position sensor events.
|
||||
* Once per crankshaft revolution we evaluate the amount of needed fuel and
|
||||
* the spark timing. Once we have decided on the parameters for this revolution
|
||||
* we schedule all the actions to be triggered by the closest trigger event.
|
||||
*
|
||||
* We also have some utility threads like idle control thread and communication threads.
|
||||
*
|
||||
*
|
||||
*
|
||||
* @section sec_trigger Trigger Decoding
|
||||
*
|
||||
* Our primary trigger decoder is based on the idea of synchronizing the primary shaft signal and simply counting events on
|
||||
* the secondary signal. A typical scenario would be when camshaft positions sensor is the primary signal and crankshaft is secondary,
|
||||
* but sometimes there would be two signals generated by two camshaft sensors.
|
||||
* Another scenario is when we only have crankshaft position sensor, this would make it the primary signal and there would be no secondary signal.
|
||||
*
|
||||
* There is no software filtering so the signals are expected to be valid. TODO: in reality we are still catching engine stop noise as unrealisticly high RPM.
|
||||
*
|
||||
* The decoder is configured to act either on the primary signal rise or on the primary signal fall. It then compares the duration
|
||||
* of time from the previous signal to the duration of time from the signal before previous, and if the ratio falls into the configurable
|
||||
* range between 'syncRatioFrom' and 'syncRatioTo' this is assumed to be the synchronizing event.
|
||||
*
|
||||
* For instance, for a 36/1 skipped tooth wheel the ratio range for synchronization is from 1.5 to 3
|
||||
*
|
||||
* Some triggers do not require synchronization, this case we just count signals.
|
||||
* A single tooth primary signal would be a typical example when synchronization is not needed.
|
||||
*
|
||||
*
|
||||
*
|
||||
*
|
||||
*
|
||||
* @section sec_scheduler Event Scheduler
|
||||
*
|
||||
* It is a general agreement to measure all angles in crankshaft angles. In a four stroke
|
||||
* engine, a full cycle consists of two revolutions of the crankshaft, so all the angles are
|
||||
* running between 0 and 720 degrees.
|
||||
*
|
||||
* Ignition timing is a great example of a process which highlights the need of a hybrid
|
||||
* approach to event scheduling.
|
||||
* The most important part of controlling ignition
|
||||
* is firing up the spark at the right moment - so, for this job we need 'angle-based' timing,
|
||||
* for example we would need to fire up the spark at 700 degrees. Before we can fire up the spark
|
||||
* at 700 degrees, we need to charge the ignition coil, for example this dwell time is 4ms - that
|
||||
* means we need to turn on the coil at '4 ms before 700 degrees'. Let's assume that the engine is
|
||||
* current at 600 RPM - that means 360 degrees would take 100ms so 4ms is 14.4 degrees at current RPM which
|
||||
* means we need to start charting the coil at 685.6 degrees.
|
||||
*
|
||||
* The position sensors at our disposal are not providing us the current position at any moment of time -
|
||||
* all we've got is a set of events which are happening at the knows positions. For instance, let's assume that
|
||||
* our sensor sends as an event at 0 degrees, at 90 degrees, at 600 degrees and and 690 degrees.
|
||||
*
|
||||
* So, for this particular sensor the most precise scheduling would be possible if we schedule coil charting
|
||||
* as '85.6 degrees after the 600 degrees position sensor event', and spark firing as
|
||||
* '10 degrees after the 690 position sensor event'. Considering current RPM, we calculate that '10 degress after' is
|
||||
* 2.777ms, so we schedule spark firing at '2.777ms after the 690 position sensor event', thus combining trigger events
|
||||
* with time-based offset.
