Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a control method and device for vehicle gears, a vehicle and a medium. BACKGROUND

[0002] The gear shift control mechanism assembly is a key component of an automobile, mainly including four gears such as P / R / N / D. With the continuous development of the automobile towards intelligence and convenience, the gear shift system of the automobile has developed from the original mechanical gear shift to the current electronic gear shift. The target demand gear is sent to the VCU (Vehicle control unit, vehicle control unit) through the CAN (Controller Area Network, controller area network) network, and the VCU judges and executes the specific gear switching operation. During operation, various gear request signals may be sent simultaneously. Without a priority control strategy, the gear shift controller may send chaotic and incorrect gear demand signals unexpectedly, leading to gear confusion and jump or gear shift failure, thereby causing vehicle accidents and seriously endangering the safety of the driver and other vehicles.

[0003] In the related art, according to the gear state of the ignition key, the gear shift controller receives the specified time for locking the P gear, and the P gear controller is controlled to realize P gear locking. Another solution is to first determine whether to prioritize after receiving the P gear in / out instruction, and then determine whether it is within the threshold. If the preset condition is met, the P gear protection instruction is executed.

[0004] However, the related art only implements the P gear protection control method, and does not mention the processing method when multiple gear request signals are sent simultaneously, which needs to be solved urgently. SUMMARY

[0005] One of the purposes of the present application is to provide a control method for vehicle gears to solve the problem of vehicle failure or accident due to unknown gear shift strategy when the driver simultaneously operates the R / N / D gear and the P gear in the prior art. The second purpose is to provide a control device for vehicle gears. The third purpose is to provide a vehicle, and the fourth purpose is to provide a storage medium.

[0006] In order to achieve the above purposes, the technical solutions adopted by the present application are as follows:

[0007] The application discloses a control method of a gear position of a vehicle, the vehicle comprising a gear shifting control mechanism and a P-gear button switch connected with the gear shifting control mechanism, wherein the method comprises the following steps: judging whether a state signal of the gear shifting control mechanism is acquired; if the state signal of the gear shifting control mechanism is acquired, determining a current gear position demand according to the state signal, and after the gear shifting control mechanism sends a gear position demand signal corresponding to the current gear position demand to a vehicle controller, judging whether a P-gear request signal of the P-gear button switch is acquired; and if the P-gear request signal is received, the gear shifting control mechanism sends the P-gear request signal to the vehicle controller; otherwise, the gear shifting control mechanism keeps sending the gear position demand signal corresponding to the current gear position demand to the vehicle controller.

[0008] According to the technical means, the P-gear button switch is separated from the gear shifting control mechanism, when the P-gear button switch and the gear shifting control mechanism are operated at the same time, the P-gear demand signal is preferentially sent, that is, the parking gear demand is higher than all gear demands, thereby avoiding disorderly sending of the gear signals, and avoiding the driver's fear caused by disorderly jumping of the gear position or the unexpected serious consequences caused by improper processing of the vehicle controller.

[0009] Further, in some embodiments, after judging whether the state signal of the gear shifting control mechanism is acquired, the method further comprises: if the state signal of the gear shifting control mechanism is not received, judging whether the P-gear request signal of the P-gear button switch is acquired; and if the P-gear request signal is acquired, the gear shifting control mechanism sends the P-gear request signal to the vehicle controller.

[0010] According to the technical means, when the driver only operates the P-gear button switch and does not operate the gear shifting control mechanism, the gear shifting control mechanism sends the P-gear demand signal to the vehicle controller.

[0011] Further, in some embodiments, after the gear shifting control mechanism sends the P-gear request signal to the vehicle controller, the method further comprises: detecting whether the P-gear request signal exists; and if the P-gear request signal does not exist, the gear shifting control mechanism sends a no-gear demand signal to the vehicle controller.

[0012] According to the technical means, after the gear shifting control mechanism sends the P-gear request signal to the vehicle controller, if the gear shifting control mechanism cannot detect the P-gear demand signal, the no-gear demand signal is sent, and the technical means solves the problem that the gear shifting mechanism cannot be operated properly due to simultaneous operation of the gear shifting control mechanism and the P-gear button switch or unexpected situations during pressing of the P-gear button.

[0013] Further, in some embodiments, after sending the gear demand signal corresponding to the current gear demand to the vehicle controller through the gear shift operating mechanism, the method further comprises: determining whether the state signal of the gear shift operating mechanism is lost; and if the state signal of the gear shift operating mechanism is lost, sending a no-gear demand signal to the vehicle controller.

[0014] According to the above technical means, if the state signal of the gear shift operating mechanism is lost after sending the current gear demand to the vehicle controller through the gear shift operating mechanism, a no-gear signal is sent, which realizes that when the R / N / D gear and the P gear are operated at the same time, the P gear button switch is released, and the gear shift operating mechanism is at the front end or the rear end, the gear shift operating mechanism assembly sends a no-gear demand signal.

[0015] Further, in some embodiments, before sending the gear demand signal corresponding to the current gear demand to the vehicle controller through the gear shift operating mechanism, the method further comprises: determining whether a gear demand signal satisfying a plurality of first preset periods is obtained; if the gear demand signal satisfying the plurality of first preset periods is received, determining whether a current gear demand satisfying a plurality of second preset periods is received, wherein the second preset period is greater than the first preset period; and if the current gear demand satisfying the plurality of second preset periods is received, sending the gear demand signal corresponding to the current gear demand to the vehicle controller through the gear shift operating mechanism.

[0016] According to the above technical means, by defining the first preset period and the second preset period, it is determined whether the current gear demand satisfies the preset period, which can realize detection of whether the gear demand signal corresponding to the gear demand is lost, and provide feedback to the driver in the case of vehicle power failure or other special situations.

[0036] The advantages and effects of the present application can be easily understood by those skilled in the art from the description of the preferred embodiments and the drawings. The present application can also be implemented or applied in different specific embodiments, and the details in the description can be modified or changed based on different views and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustration of the present application, and are not intended to limit the protection scope of the present application.

[0037] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concepts of the present application, and only the components related to the present application are shown in the diagrams, rather than being drawn according to the number, shape and size of the components in actual implementation. The shapes, number and proportions of the components in actual implementation can be arbitrarily changed, and the layout pattern of the components can be more complex.

[0038] In this embodiment, the vehicle includes a gear shift operating mechanism and a P button switch connected to the gear shift operating mechanism assembly, as shown in Figure 1 The gear shift operating mechanism includes R / N / D three gears. In order to improve the safety of the vehicle, the P button switch is physically separated from the GSM (gear shift operating mechanism assembly). The P button switch is connected to the GSM through a hard line. The GSM reads the hard line signal of the P button switch and converts the hard line signal of the P button switch into a CAN signal and sends it to the CAN network. The VCU reads the corresponding CAN signal and performs the corresponding action.

[0039] The embodiment provides a control method of a vehicle gear position, which includes the following steps: judging whether a state signal of a gear shift operating mechanism is acquired; if the state signal of the gear shift operating mechanism is acquired, determining a current gear position demand according to the state signal, and sending a gear position demand signal corresponding to the current gear position demand to a vehicle controller through the gear shift operating mechanism, then judging whether a P button request signal of a P button switch is acquired; and if the P button request signal is received, sending the P button request signal to the vehicle controller through the gear shift operating mechanism; otherwise, maintaining the sending of the gear position demand signal corresponding to the current gear position demand to the vehicle controller through the gear shift operating mechanism.

[0040] Specifically, Figure 2 A flowchart of a control method of a vehicle gear position provided by the embodiment of the present application is shown in

[0041] As shown in Figure 2 The control method of the vehicle gear position includes the following steps:

[0042] In step S201, it is judged whether a state signal of a gear shift operating mechanism is acquired.

[0043] It should be noted that, as shown in Figure 1 The state signal of the operating mechanism can be any one of the R / N / D gear positions. In addition, the embodiment of the present application sets a NO_NEED signal, indicating no gear position demand signal.

[0044] The target state signal is sent to the VCU through the CAN network. The VCU judges whether the state signal of the gear shift operating mechanism is received.

[0045] Specifically, Figure 3A physical structure diagram for sending gearshift mechanism gear position demand provided by the embodiment of the present application is shown in Figure 3 The gearshift mechanism gear position request has three states, which are 0-zero state corresponding to the vehicle being in N gear, 1-No-zero state corresponding to the vehicle being in R gear, and 2-No-zero state corresponding to the vehicle being in D gear. Only when the gearshift mechanism is moved from 0-zero state to 1-No-zero state or 2-No-zero state on the physical structure, i.e., from neutral gear to reverse gear or forward gear, the gearshift mechanism state changes on the physical structure, and the corresponding gear position demand is sent.

[0046] Optionally, in some embodiments, after determining whether the gearshift operating mechanism state signal is acquired, the method further includes: if the gearshift operating mechanism state signal is not received, determining whether a P-gear request signal of a P-gear button switch is acquired; and if the P-gear request signal is acquired, sending the P-gear request signal to the vehicle controller through the gearshift operating mechanism.

[0047] It can be understood that the gearshift operating mechanism and the P-gear button switch of the embodiment of the present application are separated on the physical structure. After the vehicle controller determines that the gearshift operating mechanism state signal is not received, it is determined that the driver does not operate the gearshift operating mechanism. Therefore, the vehicle controller needs to determine whether the P-gear request signal of the P-gear button switch is acquired. If it is detected that the driver only operates the P-gear button switch, the gearshift operating mechanism sends the P-gear request signal to the vehicle controller through the CAN network.

[0048] In step S202, if the gearshift operating mechanism state signal is acquired, the current gear position demand is determined according to the state signal, and the gearshift operating mechanism sends the gear position demand signal corresponding to the current gear position demand to the vehicle controller, and then it is determined whether the P-gear request signal of the P-gear button switch is acquired.

[0049] It should be noted that if the vehicle controller receives any state signal of the gearshift operating mechanism, it is determined that the driver operates the gearshift operating mechanism. At this time, the vehicle controller processes the corresponding gear position demand signal. Since the gearshift system of the vehicle must accurately and correctly issue a unique expected gear position demand, the P-gear priority design logic is performed in the embodiment of the present application, and thus the controller needs to determine whether the P-gear request signal of the P-gear button switch is acquired, and detect whether the gearshift operating mechanism and the P-gear button switch are operated at the same time.

[0050] Specifically, as shown in Figure 3As shown, when the vehicle driver operates the shift control mechanism, the shift mechanism is physically moved to the 1-No-zero state or the 2-No-zero state, the shift control mechanism sends a corresponding gear demand signal to the vehicle control system, and the vehicle control system judges whether the P-gear request signal of the P-gear button switch is received simultaneously after receiving the gear demand signal.

[0051] In step S203, if the P-gear request signal is received, the P-gear request signal is sent to the vehicle controller through the shift control mechanism; otherwise, the gear demand signal corresponding to the current gear demand is kept sent to the vehicle controller through the shift control mechanism.

[0052] Specifically, as shown in the schematic diagram of the P-gear demand priority logic of the embodiment of the application, when the vehicle driver operates the shift control mechanism, the control mechanism sends a corresponding gear demand signal, and if the P-gear button switch is pressed at this time, according to the P-gear priority strategy of the embodiment of the application, the P-gear demand is higher than all driving gear demands, and the shift control mechanism sends the P-gear request signal to the vehicle controller at this time. If the P-gear request signal is not received, the gear demand signal corresponding to the current gear demand is kept sent to the vehicle controller through the shift control mechanism. Figure 4 Figure 4 As shown in the schematic diagram of the P-gear demand priority logic of the embodiment of the application, when the vehicle driver operates the shift control mechanism, the control mechanism sends a corresponding gear demand signal, and if the P-gear button switch is pressed at this time, according to the P-gear priority strategy of the embodiment of the application, the P-gear demand is higher than all driving gear demands, and the shift control mechanism sends the P-gear request signal to the vehicle controller at this time. If the P-gear request signal is not received, the gear demand signal corresponding to the current gear demand is kept sent to the vehicle controller through the shift control mechanism.

[0053] Optionally, in some embodiments, after the P-gear request signal is sent to the vehicle controller through the shift control mechanism, it further includes: detecting whether the P-gear request signal exists; if the P-gear request signal does not exist, sending a no-gear demand signal to the vehicle controller through the shift control mechanism.

[0054] In this embodiment, when the P-gear button switch is pressed and remains in the pressed state, if the shift mechanism is operated during this period, since the priority of the P-gear request signal is higher than that of other gear request signals, the P-gear request signal is still sent during this period; if the P-gear button switch is released during this period, and the shift control mechanism is at the front end or the rear end, at this time the P-gear button is released, the shift action of the shift mechanism is not perfect, and therefore the gear request is switched from the P-gear to the NO_NEED signal.

[0055] Optionally, in some embodiments, after the gear demand signal corresponding to the current gear demand is sent to the vehicle controller through the shift control mechanism, it further includes: judging whether the state signal of the shift control mechanism is lost; if the state signal of the shift control mechanism is lost, a no-gear demand signal is sent to the vehicle controller.

[0056] ​In the embodiment, if the current gear shift control mechanism is kept at the front end or the last end, and the P button switch is pressed, the gear shift control mechanism sends the P request signal because the priority of the P request signal is higher than that of other gear request signals. If the P button switch is released during the process, and the gear shift mechanism is still at the front end or the last end, the gear shift mechanism does not complete the gear shift action because the P button switch is released, and the gear request signal is switched from the P request to the NO NEED signal.

[0057] Further, in some embodiments, before the gear shift control mechanism sends the gear request signal corresponding to the current gear demand to the vehicle controller, it further includes: determining whether the gear demand signal meeting the first preset period is obtained; if the gear demand signal meeting the first preset period is received, determining whether the current gear demand meeting the second preset period is received, wherein the second preset period is greater than the first preset period; if the current gear demand meeting the second preset period is received, the gear shift control mechanism sends the gear request signal corresponding to the current gear demand to the vehicle controller.

[0058] It can be understood that after the gear shift control mechanism is operated and the corresponding gear demand is sent, the situation of being interrupted by unknown reasons may occur, for example, vehicle power failure or other reasons. When the connection is successful again, the gear demand is not sent because the complete gear shift operation process is not available, the NO NEED signal is sent, and the feedback that the gear demand signal is not sent successfully is provided to the driver.

[0059] In the embodiment, the first preset period and the second preset period are set to determine whether the gear demand signal is received within the preset time, otherwise it is determined that the gear demand signal is lost, and the second preset period is greater than the first preset period. Specifically, as shown in Figure 3 The short period (t1) is the first preset period, the long period (t2) is the second preset period, and t1+t2 is a complete gear demand sending period. When the gear shift control mechanism is operated, the gear shift control mechanism sends the N frame demand signal (short period t1) in the short period first, and then continuously sends the demand signal (long period t2) in the long period after the N frame is sent. If there is no other gear demand input, the current gear long period sending is kept after the continuous N frame short period sending.

[0060] According to the vehicle gear control method provided in the embodiment of the present application, the current gear demand is determined according to the acquired state signal of the gear shift control mechanism, after the gear demand signal corresponding to the current gear demand is sent to the vehicle controller, it is judged whether the P-gear request signal of the P-gear button switch is acquired, if the signal is received, the P-gear request signal is sent to the vehicle controller through the gear shift control mechanism, otherwise, the gear demand signal corresponding to the current gear demand is kept to be sent to the vehicle controller through the gear shift control mechanism. Thus, the problem that the real vehicle malfunctions or accidents occur due to unknown gear shift strategy when the driver simultaneously operates the R / N / D gear and the P-gear is solved, a P-gear priority control strategy is provided, the vehicle accidents caused by the disorderly sending of gear signals are effectively avoided, and the safety of vehicle driving is greatly improved.

[0061] The embodiment further provides a vehicle gear control device.

[0064] The first judging module 100 is used for judging whether the state signal of the gear shift control mechanism is acquired, the second judging module 200 is used for, if the state signal of the gear shift control mechanism is acquired, determining the current gear demand according to the state signal, and after the gear demand signal corresponding to the current gear demand is sent to the vehicle controller through the gear shift control mechanism, judging whether the P-gear request signal of the P-gear button switch is acquired, and the control module 300 is used for, if the P-gear request signal is received, sending the P-gear request signal to the vehicle controller through the gear shift control mechanism, otherwise, keeping the gear demand signal corresponding to the current gear demand to be sent to the vehicle controller through the gear shift control mechanism.

[0066] Further, in some embodiments, after the P-gear request signal is sent to the vehicle controller through the gear shift control mechanism, the control module 300 is further used for detecting whether the P-gear request signal exists, and if the P-gear request signal does not exist, sending the no-gear demand signal to the vehicle controller through the gear shift control mechanism.

[0067] Further, in some embodiments, after sending the gear demand signal corresponding to the current gear demand to the vehicle controller through the gear shift control mechanism, the control module 300 is further configured to: determine whether the state signal of the gear shift control mechanism is lost; and if the state signal of the gear shift control mechanism is lost, send a no-gear demand signal to the vehicle controller.

[0068] Further, in some embodiments, before sending the gear demand signal corresponding to the current gear demand to the vehicle controller through the gear shift control mechanism, the control module 300 is further configured to: determine whether the gear shift demand signal meeting the plurality of first preset periods is obtained; if the gear shift demand signal meeting the plurality of first preset periods is received, determine whether the current gear demand meeting the plurality of second preset periods is received, wherein the second preset period is greater than the first preset period; and if the current gear demand meeting the plurality of second preset periods is received, send the gear demand signal corresponding to the current gear demand to the vehicle controller through the gear shift control mechanism.

Thus, the problem that the real vehicle fails or has an accident due to unknown gear shift strategy when the driver simultaneously operates the R / N / D gear and the P-gear is solved, a P-gear priority control strategy is provided, vehicle accidents caused by incorrect gear signal sending are effectively avoided, and the safety of vehicle driving is greatly improved.
