The present invention relates to a control device, and more specifically, from an instruction for injection control of gasoline fuel, LPG
The present invention relates to a control device such as a gasoline alternative fuel injection control device for carrying out injection control of gasoline alternative fuel such as (liquefied petroleum gas) fuel, and a control device such as a gasoline fuel injection control device for carrying out injection of gasoline fuel. .

Conventionally, a technology related to an engine system using LPG as an alternative fuel for gasoline has been proposed. For example, in Patent Documents 1 to 3 below, a base system including a gasoline engine and a gasoline ECU (gasoline control device) is added to an LPG ECU (LPG control device) and an LPG injection fuel system device (for example, , LPG tank), and the gasoline injection signal output from the gasoline ECU of the base system is
An LPG engine system is disclosed in which a PG injection signal is output after being corrected, and gasoline alternative fuel injection (that is, LPG injection) is performed by a fuel system device for LPG injection.

FIG. 1 is a block diagram schematically showing a main part of a conventional LPG engine system. L
The PG engine system includes a gasoline ECU 11 and an LPG ECU 21. The gasoline ECU 11 and the LPG ECU 21 are respectively CPU, ROM, R
Microcomputers 12 and 22 each including an AM, a backup RAM, an external input / output circuit (not shown), and the like, each ROM stores a predetermined control program related to various controls, and each RAM The calculation results of each CPU are temporarily stored, and data stored in advance is stored in the backup RAM. Further, the LPG ECU 21 includes load driving circuits 23a to 23f that drive loads such as LPG injectors INJ1 to INJ4 and shut-off valves V1 and V2 described later.

The gasoline ECU 11 includes various sensors for detecting the operating state of a gasoline engine (not shown), such as a throttle opening sensor 13, an intake pressure sensor 14, a water temperature sensor 15, an engine rotation sensor 16, an oxygen sensor. 17 is connected.
The LPG ECU 21 includes various sensors necessary for correcting the LPG injection amount in accordance with the LPG temperature state and pressure state, for example, a tank temperature sensor 2 provided in the LPG tank.
4 and a tank pressure sensor 25, and a pipe temperature sensor 26 and a pipe pressure sensor 27 provided in the delivery pipe are connected.

The gasoline engine (here, four cylinders) shifts a series of intake, compression, expansion, and exhaust strokes relative to each other for the first cylinder # 1, the second cylinder # 2, the third cylinder # 3, and the fourth cylinder # 4. While doing so repeatedly. Further, LPG injectors INJ1 to INJ4 for injecting and supplying LPG to each of the cylinders # 1 to # 4 are provided.

The gasoline ECU 11 outputs the gasoline injection signals corresponding to the first cylinder # 1, the second cylinder # 2, the third cylinder # 3, and the fourth cylinder # 4 of the gasoline engine. These output terminals 18a to 18d are connected in parallel to the input terminals 28a to 28d provided in the LPG ECU 21.

The LPG ECU 21 corresponds to each cylinder # 1 to # 4 of the gasoline engine.
The output ports 29a to 29d for outputting the PG injection signal are provided.
a to 29d are LPG injectors INJ1 to INJ provided for the respective cylinders # 1 to # 4.
4 are connected to each other. The LPG ECU 21 has output ports 29e and 29f.
These output ports 29e and 29f are connected to shut-off valves V1 and V2 for forcibly shutting off the LPG flow, respectively.

The microcomputer 12 of the gasoline ECU 11 executes gasoline injection control and ignition timing control based on signals detected by various sensors 13 to 17 and the like, and corresponds to the cylinders # 1 to # 4 with respect to the LPG ECU 21. While outputting a gasoline injection signal, the ignition signal corresponding to each cylinder # 1- # 4 is output to an ignition coil. LPG
The gasoline injection signal output to the ECU 21 is a drive signal that is originally used to drive the gasoline injector.

The microcomputer 22 of the LPG ECU 21 takes in signals output from various sensors 24 to 27 and the like, and based on these input signals, corrects the gasoline injection signal for conformity to the LPG, and sets the gasoline injection timing to LPG. Timing control for replacing the injection timing is executed, and LPG injection signals are sequentially output to the LPG injectors INJ1 to INJ4.

By the way, in such control, there is a possibility of causing various troubles if the abnormality detection of each part is not performed accurately. In some cases, it may be impossible to run, and is there any abnormality in each part? It is very important to do exactly. So, for example, L
The microcomputer 22 of the PG ECU 21 monitors the presence or absence of abnormality in the LPG engine system, and the LPG injectors INJ1 to INJ4 and the shut-off valves V1 and V2 according to instructions from the microcomputer 22
Self-diagnosis (diagnosis) is performed to check whether or not the load is operating correctly.

The reason why these loads (injector INJ1, etc.) are not driven as instructed from the microcomputer 22 is that the load itself, the load drive circuits 23a to 23f, the external load line (the microcomputer 2)
2 and a line connecting the load driving circuits 23a to 23f and a line connecting the load driving circuits 23a to 23f and the injector INJ1).

Through the above self-diagnosis, the LPG ECU 21 can determine whether or not a load such as the LPG injector INJ1 is correctly driven in accordance with an instruction from the microcomputer 22.
However, the gasoline ECU 11 cannot confirm whether the LPG injector INJ1 or the like is correctly driven in accordance with an instruction from the microcomputer 22 of the LPG ECU 21.

Therefore, the gasoline ECU 11 and the LPG ECU 21 are each provided with communication modules 19 and 30 constituted by CAN-IC so that communication between these ECUs 11 and 21 can be performed via the communication modules 19 and 30. The self-diagnosis result of the LPG ECU 21 is transmitted from the ECU 21 for gasoline to the ECU 11 for gasoline.

As a result, the gasoline ECU 11 can also check whether the injector INJ1 and the like are correctly driven in accordance with an instruction from the microcomputer 22 of the LPG ECU 21.
However, it cannot be confirmed whether the instruction from the gasoline ECU 11 is correctly reflected in the driving of the injector INJ1 or the like.

This is because, for example, an abnormality occurs in the supply lines La to Ld for supplying a gasoline injection signal from the gasoline ECU 11 to the LPG ECU 21, and the microcomputer 22 of the LPG ECU 21 misidentifies the instruction from the gasoline ECU 11. In this case, even if the injector INJ1 is correctly driven according to the instruction from the microcomputer 22, the instruction from the gasoline ECU 11 is not correctly reflected in the driving of the injector INJ1.

Even if the driving state of the load such as the injector INJ1 is transmitted from the LPG ECU 21 to the gasoline ECU 11, the gasoline ECU 11 correctly reflects the instruction from the gasoline ECU 11 on the driving of the load such as the injector INJ1. Cannot be confirmed. This is because the LPG ECU 21 performs control of LPG injection, that is, gasoline alternative fuel injection, instead of control of gasoline fuel injection originally instructed by the gasoline ECU 11.

Means for solving the problems and their effects

The present invention has been made in view of the above problems, and provides a control device that can correctly confirm the execution of alternative control that correctly reflects an instruction from another control device such as a gasoline fuel injection control device. It is an object.

In order to achieve the above object, the control device (1) according to the present invention obtains a drive signal used for driving a gasoline fuel load, which is output from the gasoline fuel injection control device, and obtains with the obtaining device. Control means for correcting and outputting the drive signal used for driving the gasoline alternative fuel load, and output means for outputting the drive signal obtained by the obtaining means to the gasoline fuel injection control device; It is characterized by having.

According to the control device (1), the drive signal used for the gasoline fuel load output from the gasoline fuel injection control device is corrected to the drive signal used for driving the gasoline alternative fuel load and output. Thereby, for example, a gasoline injection signal used for driving a gasoline injector, which is output from a gasoline fuel injection control device, can be corrected and output as a gasoline alternative fuel injection signal used for driving a gasoline alternative fuel injector. An alternative fuel engine system can be realized.

Furthermore, according to the control device (1), the acquired drive signal (that is, the drive signal output from the gasoline fuel injection control device) is output to the gasoline fuel injection control device. Therefore, the gasoline fuel injection control device can confirm whether or not the output drive signal is erroneously recognized by the control device (1). For example, it can be confirmed whether or not the output ON signal is correctly acquired as an ON signal by the control device (1) (whether it is not erroneously acquired as an OFF signal). Thereby, it is possible to confirm whether or not the alternative control that correctly reflects the instruction from the gasoline fuel injection control device is being performed.

Further, the control device (2) according to the present invention obtains a drive signal used for driving a gasoline fuel load output from the gasoline fuel injection control device, and a drive signal obtained by the obtaining device. A control means for correcting and outputting a drive signal used for driving a gasoline alternative fuel load; and an output means for outputting a drive signal used for correction by the control means to the gasoline fuel injection control device. It is characterized by having.

According to the control device (2), the drive signal used for the gasoline fuel load output from the gasoline fuel injection control device is corrected and output as the drive signal used for driving the gasoline alternative fuel load. Thereby, for example, a gasoline injection signal used for driving a gasoline injector, which is output from a gasoline fuel injection control device, can be corrected and output as a gasoline alternative fuel injection signal used for driving a gasoline alternative fuel injector. An alternative fuel engine system can be realized.

Furthermore, according to the control device (2), a drive signal used for correction by the control means (that is, a drive signal output from the gasoline fuel injection control device) is output to the gasoline fuel injection control device. The Therefore, the gasoline fuel injection control device can confirm whether or not the output drive signal is erroneously recognized by the control device (2). For example, it can be confirmed whether or not the output ON signal is correctly acquired as an ON signal by the control device (2) (whether it is not erroneously acquired as an OFF signal). Thereby, it is possible to confirm whether or not the alternative control that correctly reflects the instruction from the gasoline fuel injection control device is being performed.

By the way, when performing alternative control based on the drive signal output from the gasoline fuel injection control device, for example, the drive signal output from the gasoline fuel injection control device is input at the input terminal, and the input signal Is converted into a digital signal that can be used by the CPU, and the signal is recognized by the CPU, corrected and output.

Therefore, even if there is no misidentification at the time when the drive signal outputted from the gasoline fuel injection control device is inputted at the input terminal, it may be misidentified in the subsequent A / D conversion processing. Further, even if there is no misidentification at the time of A / D conversion processing, there is a possibility that it will be misidentified when recognized by the CPU. Therefore, it is desirable that the output to the gasoline fuel injection control device is not at the time of input at the input terminal, but closer to the end.
According to the control device (2), a drive signal used for correction by the control means is output to the main control device. That is, since the one closer to the end is output to the gasoline fuel injection control device, the accuracy can be further improved.

The control device (3) according to the present invention outputs an output means for outputting a drive signal used for driving a gasoline fuel load, acquires the drive signal output by the output means, and outputs the acquired drive signal. An acquisition means for acquiring a drive signal output from the gasoline alternative fuel injection control device, and a comparison means for comparing the drive signal output by the output means with the drive signal acquired by the acquisition means It is characterized by.

According to the control device (3), the output drive signal is compared with the drive signal acquired by the gasoline alternative fuel injection control device. It can be confirmed whether or not the output drive signal is misidentified by the gasoline alternative fuel injection control device. For example, it can be confirmed whether or not the output ON signal is correctly acquired as an ON signal by the gasoline alternative fuel injection control device (whether or not it is erroneously acquired as an OFF signal).
