Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first", "second", and the like, referred to in this application, are only used for distinguishing different devices, modules or units, and are not used for limiting the order or interdependence of functions performed by these devices, modules or units, but the terms "include", or any other variation thereof are intended to cover a non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements that are not explicitly listed, or includes elements inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The embodiment of the application provides a starting method of an engine, and as shown in fig. 1, the method comprises the following steps:
and S101, acquiring a crankshaft signal.
Wherein, the crankshaft signal is continuously collected in the starting process of the engine; a crankshaft sensor is usually mounted directly on the crankshaft for acquiring crankshaft signals at intervals. It should be noted that the interval time for acquiring the crank signal may be set according to actual conditions, and the smaller the interval time, the higher the accuracy.
Contain the tooth signal in the bent axle signal, and when appearing disturbing the tooth on the bent axle gear, the tooth signal in the bent axle signal can change, can regard this kind of tooth signal as disturbing signal, and when disturbing signal has appeared in the bent axle signal, can cause the engine to start the problem of difficulty, even unable start, serious influence user's driving experience.
As shown in fig. 2, 1# indicates a tooth signal generated by the crankshaft during the first engagement, 2# indicates a tooth signal generated by the crankshaft during the second engagement, 3# indicates a tooth signal generated by the crankshaft during the third engagement, 4# indicates a tooth signal generated by the crankshaft during the fourth engagement, and 5# and 6# have the same function and are not repeated herein. It can be seen that the waveform of the tooth signal between 5# and 6# is obviously different from the waveform of other normal tooth signals (such as 1#), and it can be understood that interference teeth appear at the position, so that the waveform of the tooth signal between 5# and 6# is changed, namely, interference signals appear; it should be noted that, the interference signal may also be caused by other situations, but the interference signal generated by any reason should be filtered out so as to avoid the engine start failure in the engine start process, and therefore, the present invention is not limited herein.
Optionally, in another embodiment of the present application, before step S101, as shown in fig. 3, the method may further include the following steps:
s301, after the power-on instruction is obtained, the control system is initialized.
The Control system is specifically an Electronic Control Unit (ECU) of the engine.
It should be noted that the power-on instruction may be a power-on instruction sent by the entire vehicle control system, or a power-on instruction sent by a user directly through a key; for example, if a user wants to get on a vehicle after getting on the vehicle, the user does not need to start the engine at this time, but may need to use other devices on the vehicle, such as an air conditioner, a sound, and the like, so that only the entire vehicle control system needs to be powered on at this time, and the electronic control unit of the engine does not need to be powered on. Under the condition, when a user wants to start the engine, the power-on instruction can be sent to the electronic control unit through the whole vehicle control system; for example, if a user wants to drive away the vehicle directly after getting on the vehicle, the entire vehicle control system and the electronic control unit of the engine can be powered on at the same time, and the user can send power-on commands to the entire vehicle control system and the electronic control unit of the engine at the same time through the keys.
Therefore, in the specific implementation process of the implementation, the electronic control unit of the engine can be initialized after the power-on instruction sent by the whole vehicle control system is obtained; or after directly acquiring a power-on instruction sent by a user through a key, initializing an electronic control unit of the engine.
S302, whether the control system is initialized successfully is judged.
Under normal conditions, the judgment can be carried out through a fault lamp, and the fault lamp of an electronic control unit of the engine is turned on and then turned off in the power-on process under normal conditions; it should be noted that, the method for judging whether the control system is successfully initialized by different vehicles may be different, and the judgment needs to be performed according to the actual situation, which is not limited herein.
It should be noted that, in the actual application process, step S302 may be executed or not according to actual situations.
Specifically, if it is determined that the control system is not successfully initialized, the step S302 is returned to be executed again; if the control system is successfully initialized, step S303 is executed.
And S303, sending a starting signal to the engine.
Specifically, after the control system, i.e., the electronic control unit of the engine, is successfully initialized, a start signal is sent to the engine, and after the engine receives the start signal, the engine starts to start.
It should be noted that a preset number of times of determination may also be set, such as 3 times, 5 times, and 10 times, which is not limited herein. When the control system, namely the electronic control unit of the engine, is not normally powered up after exceeding the preset judgment times, an alarm signal needs to be sent to the whole vehicle control system to prompt that the current control system possibly breaks down and needs to be overhauled, for example, a fault indicator lamp of the control system is on, and simultaneously, an alarm sound can be accompanied to prompt a user. The judgment interval of each time can also be set according to actual conditions, such as 5S, 7S, 30S, and the like, which is not limited herein.
S102, judging whether the duration time of the crankshaft signal is larger than the preset duration time.
In step S101, when the crank signal is acquired, the start time of acquiring the crank signal is recorded, and the duration of the crank signal is calculated while the crank signal is continuously acquired.
Since the crank signal is initially unstable and the presence of interfering teeth is more frequent, a predetermined duration is set to preferentially exclude the initially crank signal. In the duration setting process, it is necessary to set the duration to be shorter than the engine start time.
It should be noted that the preset duration is a time obtained through a plurality of tests and researches performed by a technician, and different preset durations exist for different engines, different crankshafts, and combinations of different engines and different crankshafts, and may be selected according to actual situations, which is not limited herein.
Similarly, the preset duration time can be changed according to the actual application scene, and the interference signal can be better filtered by selecting the optimal preset duration time.
Specifically, if the duration of the crank signal is greater than the preset duration, step S103 is executed.
Optionally, in another embodiment of the present application, after step S102, the following step may be further included:
and if the duration time of the crankshaft signal is judged to be less than or equal to the preset duration time, continuously acquiring the crankshaft signal.
Specifically, when the duration of the crankshaft signal is determined to be less than or equal to the preset duration, the crankshaft signal within the preset duration needs to be preferentially excluded because the crankshaft signal is very unstable at the beginning, and when the duration of the crankshaft signal is less than the preset duration, the duration of the crankshaft signal is continuously acquired until the duration of the crankshaft signal exceeds the preset duration.
S103, acquiring the number of the gear signals of the crankshaft gear.
The initial acquisition time of the number of the gear signals of the crankshaft gear is the time reaching the preset duration.
It should be noted that, the process of acquiring the number of the tooth signals of the crankshaft gear may be +1 in the count value every time one tooth signal is acquired; wherein the initial count value is generally 0; other calculation procedures are also possible. The process of acquiring the number of the gear signals of the crankshaft gear is diversified, and is not limited herein.
Specifically, at the time when the preset duration is reached, the number of crank gear tooth signals starts to be acquired.
And S104, judging whether the number of the gear signals of the crankshaft gear is larger than the preset number of the gear signals of the crankshaft gear.
Since the crank signal is unstable at the beginning and the number of the interference teeth is large, a preset duration is set, and after the crank signal at the beginning is preferentially eliminated, a preset number of the crank gear teeth is set, which can be understood as a more safety measure, so that the interference signal can be filtered to the maximum extent.
It should be noted that the preset number of the gear signals of the crankshaft gear is one number of the gear signals obtained through multiple tests and researches performed by a technician, and different preset numbers of the gear signals of the crankshaft gear may be provided for different engines, different crankshafts, and combinations of different engines and different crankshafts, and may be selected according to actual situations, which is not limited herein.
Similarly, the number of preset crankshaft gear teeth signals can be changed according to the actual application scene, and the optimal number of the preset crankshaft gear teeth signals can be selected to better filter interference signals.
Specifically, if it is determined that the number of the tooth signals of the crank gear is greater than the preset number of the tooth signals of the crank gear, step S105 is performed.
Optionally, in another embodiment of the present application, after step S104, the following step may be further included:
and if the number of the gear signals of the crankshaft gear is judged to be less than or equal to the preset number of the gear signals of the crankshaft gear, continuously acquiring the gear signals of the crankshaft gear.
Specifically, if the number of the tooth signals of the crankshaft gear is determined to be less than or equal to the number of the preset tooth signals of the crankshaft gear, it is indicated that if the engine is started at present, a starting failure condition exists, and it is necessary to continue to acquire the tooth signals of the crankshaft gear until the number of the preset tooth signals of the crankshaft gear is reached.
And S105, controlling the engine to start.
By way of example, assume that the starting time of the engine is 20S, the preset duration time of step S102 is 8S, and the number of the preset crank gear tooth signals of step S104 is 10; after the 8S crankshaft signal is acquired, the 8S crankshaft signal is filtered out, and the discarding or deleting operation can be understood as that interference teeth are easy to appear because the part of the crankshaft signal is unstable; after the 8S crankshaft signal is filtered, the number of the tooth signals is counted, when the tooth signals reach the preset number of the tooth signals of the crankshaft gear, namely 10, the tooth signals of the 10 crankshaft gears are filtered, the engine is started, and the operation of filtering the tooth signals of the 10 crankshaft gears can be understood as discarding or deleting operation, so that the interference teeth can be filtered to the maximum extent. It should be noted that the above is only an example of the present application, and in practical applications, the starting time of the engine, the number of preset crank gear tooth signals and the preset duration time are determined according to practical applications, and may be changed, so that the present application is not limited thereto.
According to the scheme, in the starting method of the engine, the crankshaft signal is acquired; wherein, the crankshaft signal is continuously collected in the starting process of the engine; then, judging whether the duration time of the crankshaft signal is greater than the preset duration time or not; if the duration time of the crankshaft signal is judged to be longer than the preset duration time, acquiring the number of the gear signals of the crankshaft gear; the starting acquisition time of the number of the gear signals of the crankshaft gear is the time reaching the preset duration; then judging whether the number of the tooth signals of the crankshaft gear is larger than the preset number of the tooth signals of the crankshaft gear; and finally, if the number of the gear signals of the crankshaft gear is judged to be larger than the preset number of the gear signals of the crankshaft gear, controlling the engine to start. So as to effectively filter the interference signal generated by the occlusion of the crankshaft gear and ensure that the engine can be normally started.
