- the duration can be expressed in crankshaft degree "° V” according to a selected angular precision (1 ° V, 1/2 ° V, 1/5 ° V or 1/10 ° V) or according to a selected temporal precision expressed in microseconds ( ⁇ s).
- the object of this invention lies in the operating principle of the TIMER PCI card which guarantees continuous engine operability while discharging the real-time activity of the CPU (Central Processor Unit) from the industrial PC-compatible microcomputer.
- Each cylinder has its own reference called "T
- Combustion (Combustion Top Dead Center), knowing that the operating order of the cylinders of a 4-stroke engine is 1/3/4/2.
- the 8 control pulses (per channel or per cylinder) can be programmed in phase and in duration compared to their TDC
- FIG. 2 shows a block diagram of the FPGA component which shows the organization adopted. It is broken down into four completely identical sub-assemblies (from cylinder 1 to cylinder 4). Each of these block diagrams is composed of: -a generation (GEN-PMH) of a TDC specific to the cylinder considered (PMH1, PMH2-, PMH3, PMH4), in which: -
- E4 58X vehicle target signal input (60-tooth wheel, 2 consecutive teeth of which are missing).

- Figure-3 shows an example of generation d ! un-signal-SH ⁇ combination of ⁇ signals Fi l, FI 2, FI 3 and F14 on the reference frame PMH1 corresponding to cylinder 1.

- Example 1 piloting a traditional 4-stroke 4-stroke petrol engine. This engine is controlled by the control of 4 ignition coils and 4 injectors. Each of these 8 actuators requires the provision of a logic output from the TIMER PCI card. Finally, each of these 8 logic outputs must have an elementary control pulse characterized by the configuration of its phasing and its duration.
- the software configuration of the TIMER PCI card from the PC compatible microcomputer will therefore consist of generating two pulses per cylinder and assigning each of these two pulses to a separate logic output. Thus, the control of the considered engine could have been achieved without any hardware modification of the TIMER PCI card.
- Example n ° 2 piloting a 4-cylinder diesel engine, 4-stroke common rail with multiple injections (8 injections per engine cycle). This engine is controlled by the control of 4 injectors.
- each of these four actuators requires the provision of a logic output from the TIMER PCI card.
- each of these 4 logic outputs must have a set of 8 elementary control pulses characterized by the configuration of their phasing and their duration.

- the scalability of the ACEbox TM system obtained thanks to the possibility of replacing the CPU of the industrial microcomputer by another more efficient CPU in order to guarantee a real time evaluation of the engine control calculations more and more relevant and therefore fast, is all the more efficient as this same CPU is relieved of the constraint of having to be responsible for sequencing, or synchronization, in real time of the actuator control pulses.
- the principle of discharging the CPU of the industrial microcomputer from the constraint of guaranteeing the sequencing of the actuator control pulses is described in the block diagram of FIG. 4, in which: A designates the task for interrupting the program "B". It is responsible for taking into account all “G” events. B designates the program for evaluating the configuration parameters (phasing and duration) of the actuator control pulses.
- - G designates the NHDL-program part of the FPGA programmable logic component of the TIMER PCI card which, on the one hand, regenerates the angular frames of reference (TDC) of the 4 cylinders in real time on the other hand, the generation of “G” events by correlation of the “E” and “F” synchronization events.

- F designates the events resulting from the angular coding of the camshaft for a 4-stroke engine (example: AAC sensor).
- G designates the synchronization events of the motor control parameter evaluation program. The frequency of this event is generally equal to the frequency of the "TDC Combustion" of the 4 cylinders of an engine, that is to say every half revolutions of the engine crankshaft. It can reach a frequency equal to the 58X vehicle target, i.e. every 6 ° V.
- H designates the configuration parameters for the control pulses of the actuators controlled by the TIMER PCI card.
- I designates the 4x4 TTL output signals (S 11 to S44 - Figure 2) for controlling the TIMER PCI card.
- the - synoptic - of figure - 4 allows - to highlight - the-simultaneous-operation-of the TIMER PCI card and of the engine control management program of the CPU of the industrial PC.
- the TIMER PCI card, as described, guarantees precise and rapid control of the motor according to the BCL1 loop: precise, because the definition of the parameters of the actuator control pulses can reach a resolution of 0.1 ° V and / or l ⁇ s. fast, because cutting the motor cycle to 0.1 ° V and / or l ⁇ s minimizes the response times of the control signals.
- control parameters for the control pulses of the TIMER PCI card actuators are updated according to the BCL2 loop, the frequency of which can reach a rhythm 1800 times slower than the frequency of the BCLl loop (for example: the BCL2 loop operated every PMH Combustion on a 4-cylinder engine and the loop
- the object of this invention resides in the operational autonomy of the TIMER PCI card which makes it possible to guarantee the continuous piloting of the motor according to the BCLl loop without requiring such intense stress on the BCL2 loop which involves the program which performs the updating. control parameters.
- the control of the actuators of the motor continues to be ensured by the loop BCL1 with constant command and control parameters corresponding to the last update.
