Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In recent years, with the development of social economy and the improvement of the living standard of people, people are pursuing more free and more individual life styles. In the field of transportation, motorcycles are favored by a large number of professional players due to unique factors such as diversified appearance and individual driving. On the other hand, under the dual driving of carbon neutralization pressure and traffic jam, some office workers gradually begin to select motorcycles which occupy a small road area and consume far less energy than automobiles as commuting tools.
The motorcycle is different from an automobile, on one hand, a user actively needs to stop working conditions of sliding in a flameout mode more, and on the other hand, the possibility that the motorcycle is dangerous is also redundant. In order to ensure the safety of motorcycle drivers, flameout of the motorcycle needs to be realized in time, so that flameout control of the motorcycle is particularly important.
Based on the requirement of active flameout of the motorcycle, two active flameout modes, namely switch flameout and knob flameout, are added on the aspect of user operation of the motorcycle; in the safety aspect of the motorcycle, two passive flameout modes of side support activation flameout and dumping flameout are added.
At present, for a multi-cylinder motorcycle, for example, an eight-cylinder motorcycle, a plurality of engine control units can be used for flameout control, but different engine control units may have different control algorithms and different control objects, so that when flameout results calculated by the plurality of engine control units are inconsistent, different engine systems on different sides respectively controlled by different engine control units are caused to operate differently, so that the engine systems are asynchronous, flameout requirements cannot be accurately met, and potential safety hazards exist. Based on the above, the application provides a control method of a motorcycle, which is used for flameout control of the motorcycle so as to ensure that an engine system of the motorcycle can keep consistent when flameout control is carried out.
The technical solution of the present application will be described below by way of specific examples.
Referring to fig. 1, which shows a schematic diagram of a Control System of a motorcycle according to an embodiment of the present disclosure, as shown in fig. 1, the Control System of the motorcycle may include a first engine Control Unit, a second engine Control Unit, a first Controller Area Network, a second Controller Area Network, a Transmission Control Unit (TCU), an Antilock Brake System (ABS), and a Body Control Module (BCM), where the Controller Area Network (CAN) may be used for information Transmission, and the first Controller Area Network may be a public Controller Area Network, that is, each Module or Unit in the System may perform information Transmission through the first Controller Area Network; the second controller area network may be a private controller area network, i.e., only the first engine control unit and the second engine control unit may exchange information over the second controller area network. Wherein:
the vehicle speed control module is used for detecting the switch state information, the knob state information and the side support state information and sending the switch state information, the knob state information and the side support state information to the first controller local area network;
the anti-lock braking system is used for detecting the angle information of the vehicle body and sending the angle information of the vehicle body to the first controller local area network;
the first engine control unit is used for acquiring the vehicle state information of the motorcycle through the first controller area network, acquiring a second flameout judgment result of the second engine control unit through the second controller area network, and determining a first flameout judgment result according to the vehicle state information;
the second engine control unit is used for acquiring the vehicle state information of the motorcycle through the first controller local area network and determining a second flameout judgment result according to the vehicle state information;
the transmission control unit is used for disconnecting the transmission chain to control the flameout of the motorcycle if a flameout command from the first engine control unit is acquired from the first controller area network. In addition, the transmission control unit can also detect the gear of the motorcycle, the speed control module can also detect the speed of the motorcycle, and the speed and the gear can also be used for assisting flameout judgment. For example, when determining whether to stall based on the side brace state, it may be determined that the assist determination is made based on the vehicle speed and the gear. When the speed of the motorcycle is greater than the preset speed and the motorcycle is not in a neutral gear, the motorcycle is indicated to be possibly in a running state at the moment, and when the opening angle of the side support is greater than the preset angle, the motorcycle can be judged to be required to be flamed out, so that potential safety hazards of the motorcycle caused by the opening of the side support are avoided; when the speed of the motorcycle is lower than the preset speed or is in a neutral gear, it can be shown that the motorcycle is not in driving, at this time, a user may push the motorcycle or the motorcycle does not start driving, at this time, the opening of the side support does not affect the safety of the motorcycle, and it can be judged that the motorcycle does not need to be flameout.
In the application, the motorcycle comprises two engine control units, one of which can be used as the main engine control unit to send a shut-down command to the transmission control unit in order to make the shut-down command received by the transmission control unit unique. The first engine control unit in fig. 1 is the main engine control unit. The second engine control unit in fig. 1 is the sub-engine control unit. The main engine control unit and the auxiliary engine control unit can adopt the same algorithm to perform flameout judgment, and whether the motorcycle needs to be flameout or not can be determined based on a flameout judgment result of the other engine control unit in the process of flameout judgment, so that the motorcycle can be flameout in time based on a judgment result of the other engine control unit when information of one engine control unit is obtained wrongly or a flameout signal cannot be identified due to judgment mistake, and the safety of motorcycle drivers is guaranteed.
Referring to fig. 2, a schematic flow chart illustrating steps of a control method of a motorcycle according to an embodiment of the present disclosure is shown, where the control method in this embodiment may be applied to the control system of the motorcycle shown in fig. 1, the motorcycle may include two engine control units, an execution subject in this embodiment may be one of the engine control units, and the following description is made by using a first engine control unit, and the control method of the motorcycle may specifically include the following steps:
s201, monitoring various vehicle state information of the motorcycle.
The vehicle state information is information for performing flameout judgment, and the plurality of types of vehicle state information at least may include switch state information, knob state information, side support state information, and vehicle body angle information. The flameout of the motorcycle may include an active flameout and a passive flameout. For example, the user may actively turn off when the user arrives at a destination or wants to stop a car. The motorcycle can comprise a knob for flameout control, and when a user rotates the knob to a specified state, a knob flameout request can be triggered, so that the motorcycle is flameout; the motorcycle may further include a switch for key-off control, and when a user activates the switch, a switch key-off request for the motorcycle may be activated, thereby turning off the motorcycle. In addition, when the self state of the motorcycle can not meet the requirement of safe driving, the motorcycle can be flamed out passively. For example, when the inclination angle of the motorcycle body is too large, the motorcycle can run continuously with great safety risk, and the motorcycle can be shut down passively; if the side support of the motorcycle is opened to a preset angle in the driving process of the motorcycle, a traffic accident may be caused, and the motorcycle can be passively flamed out at the moment. Based on the above flameout manner, in this embodiment, the flameout determination of the motorcycle can be performed based on the vehicle state information, such as the switch state information, the knob state information, the side brace state information, and the body angle information, so that the first engine control unit needs to monitor the vehicle state information, such as the switch state information, the knob state information, the side brace state information, and the body angle information, when performing the flameout control of the motorcycle.
The switch state information, the knob state information and the side support state information of the motorcycle can be detected by the vehicle speed control module. For example, the switch state information may include a switch key-off request or a no-switch key-off request, the knob state information may include a knob key-off request or a no-knob key-off request, and the side brace state information may include whether the side brace is turned on and an opening angle of the side brace. When the vehicle speed control module detects a switch flameout request, the switch state information can be determined to be the switch flameout request; when the vehicle speed control module does not detect the switch flameout request, the switch state information can be determined to be the switch-free flameout request; when the vehicle speed control module detects a knob flameout request, the switch state information can be determined to be the knob flameout request; when the vehicle speed control module does not detect the switch turn-off request, the switch state information may be determined to be a no-turn-off request. The body angle information may be detected by a brake anti-lock system. For example, the motorcycle may include an acceleration sensor, an acceleration of the motorcycle may be obtained based on the acceleration sensor, body angle information of the motorcycle may be calculated based on the acceleration, and the body angle information calculated based on the acceleration may be transmitted to a brake anti-lock system.
The anti-lock braking system, the vehicle speed control module, the first engine control unit and the second engine control unit can exchange data based on the first controller area network, so that the anti-lock braking system can send the vehicle body angle information to the first controller area network; the vehicle speed control module may send the switch state information, the knob state information, and the side brace state information to the first controller area network. The first engine control unit may obtain a plurality of types of the vehicle state information from the first controller area network.
The anti-lock braking system and the vehicle speed control module can monitor vehicle state information in real time and send the vehicle state information to the first controller local area network, and the first engine control unit can monitor various vehicle state information in real time through the first controller local area network, so that real-time flameout judgment can be carried out on various vehicle state information obtained through real-time monitoring.
It should be noted that the various monitored vehicle state information may vary according to the specific design of the motorcycle, for example, if there is no certain vehicle state information on the motorcycle, the vehicle state information may not be monitored during actual application; if other vehicle state information used for flameout judgment exists on the motorcycle, the plurality of vehicle state information can also comprise other vehicle state information used for flameout judgment.
And S202, obtaining a first flameout judgment result according to the various vehicle state information.
The first flameout judgment result can comprise flameout or non-flameout, and flameout indicates that the motorcycle needs to be controlled to flameout and fuel cut off so as to stop the motorcycle from going forward; the non-flameout means that the motorcycle can continue to run without flameout and fuel cut.
In order to guarantee safety, when any flameout signal occurs to the motorcycle, the motorcycle can be determined to be flameout. That is, if the misfire determination result determined by any one of the pieces of vehicle state information is misfire, the first engine control unit obtains a first misfire determination result based on the plurality of pieces of vehicle state information as misfire. Therefore, flameout states corresponding to the switch state information, the knob state information, the side support state information and the vehicle body angle information can be respectively determined; and if the flameout state corresponding to any one of the switch state information, the knob state information, the side support state information or the vehicle body angle information is flameout, determining that the first flameout judgment result is flameout.
Exemplarily, when the switch state information indicates that a switch flameout request exists, determining that the first flameout judgment result is flameout; when the knob state information is a knob flameout request, determining that a first flameout judgment result is flameout; when the vehicle body angle is larger than a preset angle threshold, determining that a first flameout judgment result is flameout; and when the opening angle of the side support is larger than the preset angle and the motorcycle is in a preset gear, determining that the first flameout judgment result is flameout. When the switch state information is a switch-free flameout request, the knob state information is a knob-free flameout request, the vehicle body angle is smaller than or equal to a preset angle threshold, and the angle of the side support opening is smaller than a preset angle, it can be determined that the flameout is not flameout as the first flameout judgment result.
S203, a second misfire determination result of the second engine control unit is acquired.
The second engine control unit, like the first engine control unit, can also monitor vehicle status information and implement flameout control of the motorcycle based on the same method as the first engine control unit. The second engine control unit can acquire switch state information, knob state information, side supporting state information and vehicle body angle information from the first controller local area network, and then determines flameout states corresponding to the switch state information, the knob state information, the side supporting state information and the vehicle body angle information respectively; and if the flameout state corresponding to any one of the switch state information, the knob state information, the side support state information or the vehicle body angle information is flameout, determining that the second flameout judgment result is flameout.
The first engine control unit and the second engine control unit can exchange information through the second controller area network, so that the first engine control unit can send the first flameout judgment result to the second controller area network after obtaining the first flameout judgment result, and the second engine control unit can obtain the first flameout judgment result from the second controller area network; after the second engine control unit obtains the second flameout determination result, the second flameout determination result may be sent to the second controller area network, and the first engine control unit may obtain the second flameout determination result from the second controller area network.
The first engine control unit and the second engine control unit may each collectively determine whether to stall based on the other engine control unit monitored from the second controller area network. After the second engine control unit obtains the first misfire determination result of the first engine control unit, a final misfire determination result may be obtained based on the first misfire determination result and the second misfire determination result.
And S204, controlling the motorcycle based on the first flameout judgment result and the second flameout judgment result.
In order to guarantee the safety of the driver, the motorcycle can be controlled to shut down when any flameout judgment result is flameout, so that the safety of the driver is guaranteed. Specifically, if the first flameout determination result is flameout and the second flameout determination result is flameout, a flameout command may be sent to the transmission control unit to control the transmission control unit to stop the engine according to the flameout command; if the first flameout judgment result is that the engine is not flameout, and the second flameout judgment result is that the engine is flameout, a flameout command can be sent to the transmission control unit to control the transmission control unit to stop the engine according to the flameout command; if the first flameout judgment result and the second flameout judgment result are flameout, a flameout command can be sent to the transmission control unit to control the transmission control unit to stop the engine according to the flameout command; if the first flameout judgment result and the second flameout judgment result are both not flameout, flameout is not needed, the first engine control unit may not send a flameout command to the transmission control unit, and the first engine control unit may also send a non-flameout command to the transmission control unit.
After receiving the flameout command, the transmission control unit can disconnect the transmission chain, so that the rotating speed of the engine is reduced until the engine is stopped, and the motorcycle stops moving forwards. When the transmission control unit receives no flameout command or no flameout command, the current engine running state can be continuously kept, and the motorcycle can continuously move forward.
Of course, the control logic for performing the stall control based on the first stall determination result and the second stall determination result may also be set by the user, for example, during racing of the motorcycle, the driver may want the vehicle not to stall, and therefore, the motorcycle may be stalled only when both the first stall determination result and the second stall determination result are stalled.
Fig. 3 is a schematic diagram of a misfire determination process of an engine control unit according to an embodiment of the present application, where both the first engine control unit and the second engine control unit can perform the misfire determination in the manner shown in fig. 3. As shown in fig. 3, the first engine control unit and the second engine control unit respectively have the same determination algorithm, and respectively determine whether to shut down the motorcycle according to the switch state information, the knob state information, the side stay state information, the vehicle body angle information, and the shut down determination result of the other engine control unit, and if any one of the shut down states is determined to shut down the motorcycle, the final shut down determination result is to shut down the motorcycle, and shut down and fuel off are performed. Otherwise, the flameout judgment result is that the flameout is not carried out, and the fuel cut-off is not carried out. After the flameout determination result is obtained, the flameout determination result may be sent to the second controller area network, so that another engine control unit may obtain the flameout determination result from the second controller area network and then perform flameout determination.
After the first engine control unit sends the flameout command to the transmission control unit, flameout judgment results of the first engine control unit and the second engine control unit are flameout, and if the flameout judgment results of the first engine control unit and the second engine control unit are kept flameout all the time, the motorcycle can not be restarted. Therefore, after the flameout judgment results of the first engine control unit and the second engine control unit are flameout and the flameout command is sent to the transmission control unit, the first flameout judgment result and the second flameout judgment result can be reset to be not flameout, so that the engine can be started again after being stopped. Specifically, the first engine control unit may reset the first misfire determination result to not misfire; and sending a reset instruction to the second engine control unit to control the second engine control unit to reset the second flameout judgment result to be not flameout.
Fig. 4 is a schematic diagram of a flameout reset process of an engine control unit according to an embodiment of the present application. As shown in fig. 4, in order to allow the engine to be restarted after the engine is stopped, it may be determined whether an engine stop (Crank → Stall) event is triggered, and if the engine stop event is triggered, the misfire determination results of both engine control units are reset to not misfire.
In addition, the method in this embodiment is to perform the stall control of the motorcycle, that is, to stop the operation of the engine, and the method in this embodiment is not required to be performed when the engine is in the operating state. Therefore, the engine state of the motorcycle may be detected before the step S201; if the engine of the motorcycle is in an operating state, S201 and the following steps are executed. Fig. 5 is a schematic flow chart of another control method for a motorcycle according to an embodiment of the present disclosure, and as shown in fig. 5, whether an engine is in an operating state may be detected, and if the engine is in the operating state, a method for determining flameout and fuel cut by coordination of two engine control units may be executed. The dual engine control unit coordinately determines a flameout and fuel cut method, which is a control method of a motorcycle in the present application. In the embodiment, the two engine control units can monitor various state information of the motorcycle in real time, so that flameout judgment is timely performed, flameout control is timely, and traffic accidents caused by untimely flameout control are avoided. The embodiment provides the coordinated flameout and fuel cut-off strategies of the two engine control units, and flameout judgment results of the two engine control units can be coordinated, so that the coordinated flameout consistency of the two engine control units is furthest improved under the condition that basic functions of active flameout and safe passive flameout of users are met, and the running safety of a motorcycle is improved.
It should be noted that, the sequence numbers of the steps in the foregoing embodiments do not mean the execution sequence, and the execution sequence of each process should be determined by the function and the inherent logic of the process, and should not constitute any limitation on the implementation process of the embodiments of the present application.
