[0030] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0032] In conjunction with the accompanying drawings, the vehicle transmission system jam identification method, system, device, medium and vehicle provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0033] Figure 1 FIG. 1 is a flow chart of a vehicle transmission system jam identification method provided in an embodiment of the present application. Figure 1 As shown, the vehicle transmission system jam identification method may include:

[0034] Step 101: When the vehicle is in a driving state and not in a parking state, obtain the speed and torque of the vehicle power device;

[0035] The embodiment of the present application does not limit the method used to obtain the speed and torque of the vehicle power device, and any available method can be applied to the embodiment of the present application. For example, the speed of the vehicle power device is measured by a speed sensor, and the torque of the vehicle power device is measured by a torque sensor.

[0036] The vehicles in the embodiments of the present application include but are not limited to: fuel vehicles, electric vehicles, etc. When the vehicle is an electric vehicle, the power device may be an electric motor; when the vehicle is a fuel vehicle, the power device may be a fuel engine.

[0037] For example, Figure 2 and Figure 3 As shown, Figure 2 is a schematic diagram of the vehicle speed provided in an embodiment of the present application, Figure 3 It is a schematic diagram of vehicle torque provided in an embodiment of the present application.

[0038] In some possible implementations of the embodiments of the present application, before step 101, the vehicle transmission system jam identification method provided by the embodiments of the present application may also include: obtaining the gear information and braking information of the vehicle, determining whether the vehicle is in a driving state based on the gear information, and determining whether the vehicle is in a parking state based on the braking information.

[0039] For example, when the gear information of the vehicle is neutral, it is determined that the vehicle is in a non-driving state, and when the gear information of the vehicle is non-neutral (for example, forward gear, reverse gear), it is determined that the vehicle is in a driving state. When the braking information of the vehicle is detected as braking, it is determined that the vehicle is in a parking state, and when the braking information of the vehicle is detected as not braking, it is determined that the vehicle is in a non-parking state, that is, not in a parking state.

[0040] The embodiments of the present application do not limit the method used to obtain the gear information and brake information of the vehicle, and any available method can be applied to the embodiments of the present application. When obtaining the gear information and brake information of the vehicle, the embodiments of the present application can use the gear information acquisition method in the related art to obtain the gear information of the vehicle, and the brake information acquisition method to obtain the brake information of the vehicle.

[0041] Step 102: determining a stall state of the power device based on a first comparison result between the acquired rotation speed and the rotation speed threshold;

[0042] In some possible implementations of the embodiments of the present application, the stalled state in the embodiments of the present application includes stalled and non-stalled.

[0043] In some possible implementations of the embodiments of the present application, when determining the stalled state of the power device based on the first comparison result between the acquired rotational speed and the rotational speed threshold, the stalled state of the power device can be determined by judging whether the duration for which the rotational speed is continuously less than or equal to the rotational speed threshold reaches the duration threshold. Based on this, in some possible implementations of the embodiments of the present application, step 102 may include: judging whether all the rotational speeds acquired within the first preset duration are less than or equal to the rotational speed threshold; if all the rotational speeds acquired within the first preset duration are less than or equal to the rotational speed threshold, determining that the stalled state of the power device is stalled; if part of the rotational speeds acquired within the first preset duration are less than or equal to the rotational speed threshold, determining that the stalled state of the power device is not stalled.

[0044] When there is a speed greater than the speed threshold among the acquired speeds, it means that part of the acquired speeds is less than or equal to the speed threshold, but not all of the acquired speeds are less than or equal to the speed threshold.

[0045] For example, Figure 4 shown. Figure 4 It is a schematic diagram for comparing the vehicle speed and the speed threshold provided in an embodiment of the present application.

[0046] exist Figure 3 When the speed is detected to be less than or equal to the speed threshold, the timing can be started from this time point, and the time point is counted as T1. The speed is continuously monitored. If the speed is not detected to be greater than the speed threshold at time point T2 (T2 = T1 + the first preset time length), the stalled state of the power device is determined to be stalled; if the speed is detected to be greater than the speed threshold at a certain time point between time point T1 and time point T2, the stalled state of the power device is determined to be non-stalled, and the timing is restarted from this time point, that is, the time point is counted as T1, and the stalled state of the power device is re-determined.

[0047] In some possible implementations of the embodiments of the present application, when it is monitored that the rotational speed is less than or equal to the rotational speed threshold, the time point is counted as T1. The rotational speed is continuously monitored, and when it is monitored that the rotational speed is greater than the rotational speed threshold, the time point when the rotational speed is greater than the rotational speed threshold is recorded as T2. When T2-T1 is greater than or equal to the first preset time length, the stall state of the power device is determined to be stalled; when T2-T1 is less than the first preset time length, the stall state of the power device is determined to be non-stalled.

[0048] Step 103: determining a driving state of the power device based on a second comparison result between the acquired torque and the torque threshold;

[0049] In some possible implementations of the embodiments of the present application, the driving state of the power device in the embodiments of the present application includes being in a target driving state and being in a non-target driving state.

[0050] In some possible implementations of the embodiments of the present application, when determining the driving state of the power device based on the second comparison result between the acquired torque and the torque threshold, the driving state of the power device can be determined by judging whether the duration of time when the torque is greater than the torque threshold reaches the duration threshold within a specific duration. Based on this, in some possible implementations of the embodiments of the present application, step 103 may include: judging whether the first duration is greater than or equal to the duration threshold, wherein the first duration is the duration corresponding to the torque acquired within the second preset duration being greater than the torque threshold; when the first duration is greater than or equal to the duration threshold, determining that the driving state of the power device is in the target driving state; when the first duration is less than the duration threshold, determining that the driving state of the power device is in the non-target driving state.

[0051] For example, Figure 5 shown. Figure 5 It is a schematic diagram comparing vehicle torque and torque threshold provided in an embodiment of the present application.

[0052] exist Figure 5 In the example, within 2000 milliseconds (ms), the duration that the vehicle torque is greater than the torque threshold is 200+400+400=1000 ms.

[0053] Assuming that the duration threshold is 900 ms, within 2000 ms, the duration of 1000 ms during which the vehicle torque is greater than the torque threshold is greater than the duration threshold 900 ms, and it is determined that the driving state of the power device is in the target driving state.

[0054] Assuming that the duration threshold is 1200ms, within 2000ms, if the duration of 1000ms during which the vehicle torque is greater than the torque threshold is less than the duration threshold 1200ms, it is determined that the driving state of the power device is in a non-target driving state.

[0055] It can be understood that, in this embodiment, the second preset time length is 2000 ms.

[0056] Step 104: Based on the stall state and the driving state of the power unit, identify the stuck state of the vehicle transmission system.

[0057] In some possible implementations of the embodiments of the present application, step 104 may include: when the power unit is in a stalled state and the power unit is in a target driving state, determining that the vehicle transmission system is in a stuck state; when the power unit is in a non-stalled state and / or the power unit is in a non-target driving state, determining that the vehicle transmission system is in a non-stuck state.

[0058] When the power unit is in a stalled state but the power unit is in a non-target driving state, or the power unit is in a non-stalled state but the power unit is in a target driving state, or the power unit is in a non-stalled state but the power unit is in a non-target driving state, it is determined that the vehicle transmission system is not stuck; when the power unit is in a stalled state and the power unit is in a target driving state, it is determined that the vehicle transmission system is stuck.

[0059] In the embodiment of the present application, when the vehicle is in a driving state and not in a parking state, the rotation speed and torque of the vehicle power device are obtained; based on the first comparison result of the obtained rotation speed and the rotation speed threshold, the stall state of the power device is determined; based on the second comparison result of the obtained torque and the torque threshold, the driving state of the power device is determined; based on the stall state and driving state of the power device, the stuck state of the vehicle transmission system is identified. In this way, the stuck state of the vehicle transmission system can be identified, and then, in the case that the vehicle cannot drive after the gear is engaged, it can be determined whether the inability of the vehicle to drive after the gear is engaged is caused by the stuck state of the vehicle transmission system.

[0060] In some possible implementations of the embodiments of the present application, the vehicle transmission system jam identification method provided in the embodiments of the present application may also include: when it is determined that the vehicle transmission system is in a jam state, pushing an alarm message to the user, wherein the alarm message is used to prompt the user that the vehicle transmission system is jammed.

[0061] In some possible implementations of the embodiments of the present application, an alarm message for reminding the user that the vehicle transmission system is stuck can be pushed to the user by voice or display. When the user learns that the vehicle transmission system is stuck through the alarm message, the vehicle can be repaired. After the vehicle is repaired, when the vehicle transmission system is identified to be stuck again, the vehicle transmission system is not stuck.

[0062] In the embodiment of the present application, by pushing an alarm message to the user to remind the user that the vehicle transmission system is stuck, the user can be informed that the vehicle transmission system is stuck, and then repair the vehicle in time to solve the problem of the vehicle transmission system being stuck.

[0063] In some possible implementations of the embodiments of the present application, after pushing the alarm information to the user, the vehicle transmission system jam identification method provided by the embodiments of the present application may also include: when it is determined that the vehicle transmission system has switched to an unstuck state, stopping pushing the alarm information used to prompt the user that the vehicle transmission system is stuck.

[0064] In some possible implementations of the embodiments of the present application, after pushing an alarm message to the user to prompt the user that the vehicle's transmission system is stuck, the speed and torque of the vehicle's power unit can continue to be obtained, and the stalled state of the power unit is determined based on a first comparison result between the acquired speed and the speed threshold; the driving state of the power unit is determined based on a second comparison result between the acquired torque and the torque threshold; the stuck state of the vehicle's transmission system is identified based on the stalled state and the driving state of the power unit; when it is determined that the vehicle's transmission system is not stuck based on the stalled state and the driving state of the power unit, the stuck fault of the vehicle's transmission system is cleared, and at this time there is no need to push an alarm message to the user to prompt the user that the vehicle's transmission system is stuck, and therefore, the alarm message to the user to prompt the user that the vehicle's transmission system is stuck can be stopped from being pushed to the user.

[0065] Figure 6 It is a logical schematic diagram for identifying the stuck state of a vehicle transmission system provided in an embodiment of the present application.

[0066] exist Figure 6 In the method, the gear information and brake information of the vehicle are first obtained, the driving state of the vehicle is determined based on the gear information of the vehicle, and the parking state of the vehicle is determined based on the brake information of the vehicle. When it is determined that the vehicle is in a driving state and in a non-parking state, the speed and torque of the vehicle power device are obtained. Based on the first comparison result of the obtained speed and the speed threshold, the stalled state of the power device is determined; based on the second comparison result of the obtained torque and the torque threshold, the driving state of the power device is determined; based on the stalled state and the driving state of the power device, the stuck state of the vehicle transmission system is identified. When the power device is in a stalled state and the power device is in a target driving state, it is determined that the vehicle transmission system is in a stuck state. When the power device is in a stalled state but the power device is in a non-target driving state, or the power device is not in a stalled state but the power device is in a target driving state, or the power device is not in a stalled state but the power device is in a non-target driving state, it is determined that the vehicle transmission system is in a non-stuck state.
