The specific embodiment is as follows:
the invention will be further described with reference to the drawings and examples.
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.
Noun interpretation:
ECU (Electronic Control Unit): an electronic control unit, which is also called a driving computer, a vehicle-mounted computer and the like. The microcomputer controller is specially used for automobiles. It is composed of microprocessor (CPU), memory (ROM, RAM), input/output interface (I/O), A/D converter (A/D), shaping and driving large-scale integrated circuits. The term "ECU" is simply the brain of the vehicle ".
Example 1:
the engine is used as a power source of the whole vehicle, and the load output device runs along with the engine when the engine runs, so that the working mode has the following defects: (1) the starting resistance is large: the existing load output device synchronously rotates along with the engine, and in the starting process of the engine, partial power of the engine is used for running the load output device, so that the starting resistance of the engine is increased, and the starting success rate in a low-temperature environment is particularly reduced; (2) flameout problem: in a cold state, particularly in a plateau low-temperature environment, the engine needs to be idle for a period of time to realize full power output; if the load output device is operated all the time in a cold state, the output power requirement of the engine is increased, the load rate is overlarge, the problem of flameout of the engine is easily caused, and even the reliability of the engine is reduced.
In view of the above problems, the present embodiment provides an engine start control method considering load output, including:
acquiring a closing signal of an engine starting switch;
the obtained closing signal of the engine starting switch is taken as a judgment basis, the load output device is controlled to enter a non-working mode, and the starter is controlled to work, so that the engine is started;
when the engine speed exceeds the exiting speed of the starter, judging whether the engine has full power output capability, if so, controlling the load output device to enter a working mode, and if not, continuously controlling the load output device to be in a non-working mode until the engine has full power output capability.
According to the method provided by the embodiment, the closing signal of the engine starting switch is used as the judging signal for controlling the load output device to be in the non-working mode, so that the control delay problem is solved, and the problems that the load output device is frequently started and stopped and the service life of the load output device is influenced when the engine is started are avoided; meanwhile, the collection and processing of excessive signals increase the control calculation difficulty, and when the engine is started and does not have full power output, the load device is prohibited from running, so that the load rate and the starting resistance of the engine are reduced, the problem of flameout of the starter is avoided, and the starting success rate and the reliability of the engine are improved.
The specific control logic of this embodiment is shown in fig. 1, and two control strategies are added in the running process of the engine, specifically:
in the embodiment, when the ECU receives the ignition switch T50 closing signal during the engine starting process control, the ECU synchronously transmits the signal to the load output device and the starter control device, firstly, a 'disconnection' instruction is always transmitted to the load output device during the starting process, so that the load output device is controlled in a non-working mode, the load output device is forbidden to run, the engine load rate and the starting resistance are reduced, and the engine starting success rate and the reliability are improved; and then transmitting an instruction for closing an electromagnetic switch of the starter to the starter, controlling the starter to start to enter a working mode, and performing an engine starting process.
The method comprises the steps that an ignition switch T50 closing signal is used as a judging condition of whether a load output device operates or not, an ECU receives the ignition switch T50 closing signal as an opening end for transmitting an 'disconnection' instruction to the load output device by the ECU, when an engine is ready to start, the load output device is forbidden to operate, the engine load rate and the starting resistance are reduced from the opening end, the engine starting success rate is greatly improved, and the control delay phenomenon is avoided; and when the ECU judges that the engine speed exceeds the exiting speed of the starter, the starting is judged to be successful, and the ECU judges whether the engine has a full-power output capacity judging mode.
In this embodiment, after the engine is successfully started, the ECU automatically checks whether the full power output condition is satisfied, if the full power output condition is not satisfied yet, the ECU continues to transmit the "disconnection" instruction to the load output device, and prohibits the load output device from running, so as to avoid the forced running mode, and cause the occurrence of the engine stall problem and the reduction of reliability due to the excessive load rate of the engine. If the engine state has satisfied the full power output condition, the ECU ceases to transmit a "disconnect" command to the load output device, allowing the load output device to enter an operational mode.
In the present embodiment, the engine load output capability determination condition is increased; after the engine is successfully started, the ECU performs engine load capacity condition check, and from the aspects of engine reliability and environmental conditions, whether the engine has a full-power output condition is set to be whether a judgment value T0 is larger than a preset value T1 or not; the judging value T0 is a measured value, and specifically is a minimum value of the water temperature and the engine oil temperature in the current state of the engine; the preset value T1 is the minimum value of the required water temperature and engine oil temperature when the engine has full power output capability under different atmospheric pressures; if the T0 is more than or equal to the T1 value, the ECU stops transmitting a disconnection instruction to the load output device and allows the load output device to enter a working mode; if T0 < T1, the ECU continues to transmit a disconnection instruction to the load output device, and the load output device is prohibited from entering an operating mode.
According to the actual running condition of the engine, starting from the angle of preventing risks in advance, firstly, the load output device is forbidden to enter the working mode from the start of starting, the load rate and the starting resistance of the engine are reduced, and the starting success rate and the reliability of the engine are greatly improved; and secondly, judging whether the engine has full power output capability or not is increased, the reliability of the engine is ensured to the greatest extent, and the occurrence probability of the engine flameout problem is reduced.

The working method of the system is the same as the engine start control method of embodiment 1 considering the load output, and will not be described here again.
