[0040] As mentioned above, some rail routes currently have long and steep slopes that fail to meet the 20‰ slope requirement. For example, the Xicheng Railway has a 45-kilometer-long 25‰ slope. Under normal circumstances, the starting traction of rail transit vehicles, such as EMUs, can meet normal operating requirements. However, if a fault causes the EMU to experience power loss, the actual power may not be sufficient to operate on the long and steep slopes, causing the EMU to stop on the long and steep slopes due to insufficient starting traction, which poses a significant risk.

[0041] To address the aforementioned issues, embodiments of the present application provide a vehicle control method. The method may include obtaining the operating status of the vehicle's traction system while the vehicle is stationary and in a power-loss condition, thereby determining, based on the operating status of the traction system, whether the traction system meets the conditions for entering a high acceleration mode. Then, in response to a high acceleration mode entry trigger operation, the traction system may be controlled to operate in the high acceleration mode.

[0042] In this way, when the traction system meets the entry conditions of the high acceleration mode, the high acceleration mode can enable the vehicle to improve its traction capacity in a short period of time, so that it can operate normally on long and steep slopes in the event of power loss, avoiding the situation where the vehicle is stopped on long and steep slopes, thereby reducing operational risks.

[0043] It should be noted that the embodiments of the present application do not limit the execution subject of the vehicle control method. For example, the vehicle control method of the embodiments of the present application can be applied to data processing devices such as terminal devices or servers. The terminal device can be a smartphone, a computer, a personal digital assistant (PDA), an in-vehicle smart terminal, or a tablet computer. The server can be a standalone server, a cluster server, or a cloud server.

[0044] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] Figure 1 A flow chart of a vehicle control method provided in an embodiment of the present application. Figure 1 As shown, the vehicle control method provided by the embodiment of the present application may include:

[0046] S101: When the vehicle is stationary and in a power loss condition, obtain the operating status of the vehicle's traction system.

[0047] In rail transit, during normal operation, a vehicle can start with 100% traction output to meet the operating requirements of various lines. However, in actual use, the vehicle may be in a power loss condition due to various faults. For example, the vehicle is pulling at 50% traction output, resulting in a 50% power loss. In this case, if the vehicle is running on a long slope, due to insufficient power, the vehicle will find it difficult to overcome the resistance, causing the vehicle to stop on the long slope, thus entering a state of stationary vehicle and power loss. Among them, under the power loss condition, the range of starting traction loss can be between 0 and 50%, and this embodiment of the application does not specifically limit this.

[0048] The traction system of the vehicle may specifically include a traction motor and a traction motor fan. Accordingly, the operating state of the traction system may include the operating temperature of the traction motor and the operating speed of the traction motor fan. The operating temperature of the traction motor can be collected by setting one or more temperature sensors at the traction motor. Specifically, when multiple temperature sensors are set, the temperature values ​​collected by the multiple temperature sensors can be averaged, and the average value is used as the operating temperature of the traction motor. The embodiment of the present application may not specifically limit the number of temperature sensors to be set. As for the operating speed of the traction motor fan, a speed sensor can be set at the traction motor fan, and the speed sensor can be used to collect the speed. Specifically, when multiple speed sensors are set, the speed values ​​collected by the multiple speed sensors can be averaged, and the average value is used as the operating speed of the traction motor fan. The embodiment of the present application may not specifically limit the number of speed sensors to be set.

[0049] S102: Determine, based on the operating state of the traction system, whether the traction system meets the conditions for entering the high acceleration mode.

[0050] In the embodiments of this application, high acceleration mode specifically refers to an operating mode that increases traction for a short period of time when a rail transit vehicle is started from a standstill. Specifically, high acceleration mode increases the starting current of the traction motor by adjusting the traction converter, thereby increasing the starting torque of the traction motor and thereby increasing the starting traction force.

[0051] In addition, the embodiment of the present application may not specifically limit the implementation method for determining that the traction system meets the entry conditions of the high acceleration mode, that is, S102. For ease of understanding, it is described below in conjunction with a possible implementation method.

[0052] In one possible embodiment, S102 may specifically include: determining that the operating state meets the entry condition when the operating temperature is less than or equal to a preset temperature and the operating speed is within a preset speed range; and adjusting the operating temperature and operating speed so that the operating state meets the entry condition when the operating temperature is greater than the preset temperature. In actual applications, when the traction system enters high acceleration mode, the temperature rise of the traction motor increases rapidly. Therefore, to prevent damage to the traction motor due to excessive temperature, the preset temperature may be the difference between the critical failure temperature of the traction motor and the temperature rise value of the traction motor. Furthermore, the preset speed range may be the speed range of the traction motor fan when operating at high speed. In this way, the high-speed operation of the traction motor fan can cool the traction motor, thereby ensuring that the traction motor maintains a safe temperature after entering high acceleration mode, thereby ensuring its performance.

[0053] Furthermore, when the operating temperature is greater than a preset temperature, the operating temperature and operating speed adjustment process may specifically include: adjusting the operating speed to a preset speed range to utilize the wind generated by the traction motor fan to cool the traction motor; determining that the operating state meets the entry condition when the operating temperature is less than or equal to the ambient temperature of the vehicle's environment; and the ambient temperature is less than or equal to the preset temperature. In this manner, logically controlling the operating temperature of the traction motor based on the preset temperature and the ambient temperature of the vehicle's environment, and determining the entry condition for high acceleration mode in conjunction with the operating speed of the traction motor fan, can help maintain a safe temperature for the traction motor after entering high acceleration mode, thereby ensuring its performance.

[0054] S103 : In response to the high acceleration mode entry triggering operation, controlling the traction system to operate in the high acceleration mode.

[0055] In an embodiment of the present application, the high acceleration mode entry triggering operation may specifically include: a control corresponding to a high acceleration mode entry command on the vehicle's human-machine interface being triggered and outputting a high acceleration mode entry command; and / or a traction handle of the traction system being switched to a switch position corresponding to a high acceleration mode gear under the action of an external force and outputting a high acceleration mode gear position signal. If high acceleration mode is entered when either of these two entry triggering operations is satisfied, operation of the traction system in high acceleration mode can be simplified and quickly achieved. If high acceleration mode is entered when both of these entry triggering operations are satisfied, false triggering of high acceleration mode can be prevented, thereby preventing damage to the traction system caused by false entry into high acceleration mode. Furthermore, in an embodiment of the present application, if the high acceleration mode entry triggering operation is executed when the traction system does not always meet the high acceleration mode entry conditions, the entry triggering operation is invalid, meaning that the traction system cannot be controlled to operate in high acceleration mode, thereby further preventing traction system failures caused by false triggering of high acceleration mode.

[0056] Furthermore, the implementation process of controlling the traction system to operate in the high acceleration mode, namely S103, may specifically include controlling the starting current of the traction motor to increase to increase the starting traction force of the traction system. To facilitate understanding of the process of increasing the starting traction force of the traction system, a detailed description may be provided with reference to the accompanying figures. Figure 2 A schematic diagram of a traction characteristic curve of a traction system provided in an embodiment of the present application. Figure 2 As shown, the power loss condition is based on the example of a vehicle outputting 50% traction. When the vehicle normally outputs 50% traction, its starting traction can be 120 kN; and when the vehicle outputs 50% traction in high acceleration mode, its starting traction can be 142 kN. It can be seen that when the traction system is controlled to operate in high acceleration mode, the traction system will only be overloaded by about 18% (calculated as 142 / 120-100%) for a short period of time. In this way, the starting traction of the vehicle can be increased in a short period of time without causing damage to the traction system, so that the vehicle can start and operate normally on a long slope in the event of power loss, avoiding the situation where the vehicle is stopped on a long slope, thereby reducing operational risks.

[0057] In addition, in an embodiment of the present application, an exit condition for high acceleration mode can also be set to prevent the traction system from continuing to operate in high acceleration mode, which may cause the traction motor to overheat and affect performance, or even cause a malfunction. Specifically, the vehicle control method may further include: controlling the traction system to exit high acceleration mode when the vehicle stops again and / or the vehicle's running distance in high acceleration mode is greater than or equal to a preset distance. In actual applications, the preset distance is, for example, 5 kilometers to 10 kilometers. In this way, when the vehicle's running distance in high acceleration mode reaches the preset distance, the vehicle can obtain sufficient starting traction to overcome resistance, so that it can start and operate normally on a long slope in the event of power loss. At this time, the high acceleration mode can be exited to avoid unnecessary losses in the traction system.

[0058] Based on the above-described S101-S103, it can be seen that in this embodiment of the present application, while the vehicle is stationary and experiencing a power loss condition, the operating status of the vehicle's traction system can be obtained, so that, based on the operating status of the traction system, it can be determined whether the traction system meets the conditions for entering high acceleration mode. Then, in response to a triggering operation to enter high acceleration mode, the traction system can be controlled to operate in high acceleration mode. In this way, when the traction system meets the conditions for entering high acceleration mode, high acceleration mode can be used to briefly increase the vehicle's traction capacity, allowing it to operate normally on long and steep slopes even in the event of a power loss, preventing the vehicle from being parked on long and steep slopes and thus reducing operational risks.

[0059] Furthermore, to optimize the vehicle's control logic and enhance its intelligence, embodiments of the present application may also incorporate a false trigger mechanism, allowing the high acceleration mode entry trigger to execute only when the traction system meets the high acceleration mode entry conditions. Accordingly, embodiments of the present application may provide another vehicle control method, which specifically includes steps S301-S304. Steps S301-S304 are described below in conjunction with the embodiments and accompanying figures.

[0060] Figure 3 This is a flow chart of another vehicle control method provided in an embodiment of the present application. Figure 3 As shown, the vehicle control method provided by the embodiment of the present application may include:

[0061] S301: When the vehicle is stationary and in a power loss condition, obtain the operating status of the vehicle's traction system.

[0062] In the embodiment of the present application, the specific implementation of S301 can refer to the relevant content of S101 in the above embodiment, which will not be repeated here.

[0063] S302: Determine, based on the operating state of the traction system, whether the traction system meets the conditions for entering the high acceleration mode.

[0064] In the embodiment of the present application, the specific implementation of S302 can refer to the relevant content of S102 in the above embodiment, and will not be repeated here.

[0065] S303: The human-machine interaction interface for controlling the vehicle provides a control corresponding to the high acceleration mode entry instruction.

[0066] In this way, after determining that the traction system meets the entry conditions of the high acceleration mode, the human-computer interaction interface provides controls corresponding to the high acceleration mode entry instructions, allowing the user to operate and trigger the entry trigger operation of the high acceleration mode, thereby realizing the false trigger mechanism of the high acceleration mode.

[0067] S304: In response to the control being triggered, outputting a high acceleration mode entry instruction to control the traction system to operate in the high acceleration mode.

[0068] Furthermore, to optimize the vehicle's control logic and enhance its intelligence, embodiments of the present application may also incorporate a false trigger mechanism, allowing the high acceleration mode entry trigger to execute only when the traction system meets the high acceleration mode entry conditions. Accordingly, embodiments of the present application may provide another vehicle control method, which specifically includes steps S401-S404. Steps S401-S404 are described below in conjunction with the embodiments and accompanying figures.

[0069] Figure 4This is a flow chart of another vehicle control method provided in an embodiment of the present application. Figure 4 As shown, the vehicle control method provided by the embodiment of the present application may include:

[0070] S401: When the vehicle is stationary and in a power loss condition, obtain the operating status of the vehicle's traction system.

[0072] S402: Determine, based on the operating state of the traction system, whether the traction system meets the conditions for entering the high acceleration mode.

[0073] In the embodiment of the present application, the specific implementation of S402 can refer to the relevant content of S102 in the above embodiment, and will not be repeated here.

[0074] S403: Control the limiting component of the traction handle to open the switching position corresponding to the high acceleration mode gear.

[0075] In this way, after determining that the traction system meets the entry conditions of the high acceleration mode, the limiting component of the traction handle opens the switching position corresponding to the high acceleration mode gear, so that the traction handle can enter the switching position under the action of external force and switch to the high acceleration mode gear, thereby realizing the false triggering mechanism of the high acceleration mode.

[0076] In addition, in the embodiment of the present application, the limiting component can also resist the switching position of the high acceleration mode gear to limit the traction handle from entering the switching position, thereby limiting its switching to the high acceleration mode gear.

[0077] S404: In response to the traction handle of the traction system being switched to the switching position under the action of an external force, a high acceleration mode gear signal is output to control the traction system to operate in the high acceleration mode.
