DETAILED DESCRIPTION

[0068] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0069] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0070] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0071] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0072] With the rapid development of the automobile industry and the continuous advancement of automatic transmission technology, automatic transmission, as a key component of the vehicle transmission system, has become an indispensable part of modern vehicles.

[0073] The automatic transmission is intelligent and automated, and is responsible for effectively transmitting the engine's power to the wheels. Specifically, the automatic transmission relies on vehicle speed sensors and acceleration sensors to obtain real-time data, and by analyzing the real-time data, it can infer the current slope of the vehicle. If the vehicle is identified as being uphill based on the inferred slope, the automatic transmission will adjust its shifting logic, which means it will select a suitable gear to provide enough power and torque to help the vehicle climb the slope smoothly.

[0074] Although the automatic transmission can identify the current slope through the vehicle speed sensor and acceleration sensor, it cannot predict the road conditions ahead. This means that the automatic transmission can only adjust according to the current road conditions, but cannot prepare for the upcoming slope changes in advance.

[0075] Since the road conditions ahead cannot be predicted, the automatic transmission may not be able to select the most appropriate gear shifting logic, which may result in the vehicle failing to adjust to the most appropriate gear in time when climbing a slope, affecting the vehicle's power output and overall efficiency.

[0076] Once the vehicle's power output and overall efficiency are affected, it may cause the vehicle to consume more energy when climbing a slope. This is because the automatic transmission cannot shift gears at the most appropriate time, causing the engine to require additional power to overcome the slope, thereby increasing fuel or motor consumption.

[0077] In response to the above technical problems, the inventor found that when studying the climbing process of the vehicle, the real-time data collected by the automatic transmission can only infer the current slope, but cannot predict the road conditions ahead. Therefore, the inventor thought of obtaining the relevant parameters of the uphill road and the vehicle in advance when the vehicle reaches the bottom of the slope, and determining the gear that enables the vehicle to complete the climbing based on the obtained parameters. Further analysis of the energy consumption corresponding to each climbing gear allows the vehicle to climb the slope according to the gear corresponding to the lowest energy consumption, thereby saving the energy consumption generated by the vehicle during the climbing process.

[0078] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0079] An embodiment of the present application provides a vehicle shifting method for an uphill road. Figure 1 A schematic diagram of a vehicle shifting method for an uphill road provided in an embodiment of the present application Figure 1 ,like Figure 1 As shown, the vehicle shifting method facing an uphill road includes:

[0080] S101. Obtain road information parameters of a target uphill road and vehicle information parameters of a target vehicle.

[0081] The road information parameters refer to various information related to the target uphill road, including the slope, slope length, and road resistance coefficient of the target uphill road. The road information parameters are very important for analyzing and predicting the performance of the vehicle on the target uphill road.

[0082] The target vehicle represents a vehicle that is about to travel on the target uphill road. The vehicle information parameters of the target vehicle may include the position, speed, load, engine torque, gear position, etc. of the target vehicle.

[0083] Explanatory, since the high-precision three-dimensional map provides detailed road information, including the road's geometry, slope, curvature, width, and other features (such as traffic signs, signal light locations, etc.), the required road information parameters of the target uphill road can be obtained through the high-precision three-dimensional map.

[0084] In addition, the current location of the target vehicle and the target uphill road to be driven on can be identified through the Global Positioning System (GPS). Vehicle information parameters such as vehicle speed, load, engine torque, and gearbox gear usually need to be obtained through the vehicle's own sensors and systems.

[0085] In a specific example, the length, slope, road adhesion coefficient of the target uphill road, and the distance between the target vehicle and the bottom of the target uphill road are first obtained based on GPS and high-precision three-dimensional maps. Secondly, the speed, load, engine torque, and gearbox gear of the vehicle before climbing are obtained through the controller area network (CAN) device. Among them, the CAN device is a network protocol used for internal communication in the vehicle. The CAN bus system can transmit various vehicle parameters and status information.

[0086] S102: Determine a climbing gear of the target vehicle based on a preset gear shifting logic according to the road information parameters and the vehicle information parameters.

[0087] Specifically, the gear position of the target vehicle when it reaches the bottom of the target uphill road is regarded as the target gear position. The target gear position also belongs to the vehicle information parameter of the target vehicle. Next, according to the road information parameter and the vehicle information parameter, it is determined based on a preset algorithm whether the target vehicle can pass the target uphill road with the target gear position. If so, the target gear position is determined as the first gear position.

[0088] It can be understood that the first gear can provide sufficient torque to overcome the gravity effect of the slope, ensuring that the target vehicle maintains a constant gear during the climbing process.

[0089] In a possible implementation, judging whether the target vehicle can pass the target uphill road at the target gear position based on the preset algorithm specifically includes: obtaining historical vehicle information parameters of historical vehicles traveling on the target uphill road within the target historical time period, and training the preset algorithm based on the road information parameters and the historical vehicle information parameters to obtain a trained preset algorithm. Further, the road information parameters and the vehicle information parameters are input into the trained preset algorithm to judge whether the target vehicle can pass the target uphill road at the target gear position.

[0090] It should be noted that the preset algorithm may adopt a backpropagation (BP) neural network algorithm. The BP neural network algorithm is a commonly used artificial neural network training algorithm, which adjusts the weight of the network by backpropagating errors, so that the network can learn the complex relationship between input and output. In addition, the preset algorithm may also adopt other algorithms that can achieve the above-mentioned prediction function, which are not specifically limited here.

[0091] In a specific example, the BP neural network algorithm is trained based on the collected road information parameters related to the target uphill road (such as slope, slope length, and road resistance coefficient, etc.), and the historical vehicle information parameters (such as vehicle speed, load, engine torque, gearbox gear, etc.) that passed the target uphill road in the historical time period. It should be understood that the goal of the training is to let the BP neural network algorithm learn the relationship between the input parameters (road information parameters and historical vehicle information parameters) and the output results (whether the target uphill road can be passed).

[0092] During the training process, the back propagation algorithm can also be used to adjust the weights and biases of the neural network to minimize the prediction error. After the training is completed, the road information parameters and the vehicle information parameters of the target vehicle that is about to climb the slope are input into the trained BP neural network algorithm, and the prediction result is output, that is, whether the target vehicle can pass the target uphill road in the target gear.

[0093] It is worth explaining that after determining that the target vehicle can pass the target uphill road with the target gear, downshift processing can be further considered to optimize the fuel efficiency of the target vehicle and find the most energy-efficient climbing gear.

[0094] Specifically, a first downshift operation is performed on the target vehicle based on a first preset downshift logic, wherein the first preset downshift logic includes downshifting before a slope or downshifting during a slope. If the first preset downshift logic is downshifting before a slope, the second gear position of the target vehicle after downshifting before a slope is determined. If the first preset downshift logic is downshifting during a slope, the third gear position of the target vehicle after downshifting during a slope is determined.

[0095] It should be understood that the target vehicle can pass the target uphill road in the second gear or the third gear. In other words, the first gear, the second gear, and the third gear are all climbing gears of the target vehicle.

[0096] It should be noted that the first preset downshift logic relies on the management of engine torque. When the target vehicle can complete the climb in the target gear, the engine torque required in the target gear can be determined by dynamic calculation. When further considering downshifting to optimize performance or efficiency, it is necessary to ensure that the engine torque after downshifting can meet or exceed the engine torque required in the target gear.

[0097] In a possible implementation, the engine torque required for the target vehicle to pass the target uphill roadblock in the target gear is determined. If the first preset downshift logic is downshift before the slope, the target vehicle is downshifted before the slope based on the first preset downshift logic according to the engine torque, and the second gear of the target vehicle after the downshift before the slope is determined.

[0098] If the first preset downshift logic is downshift on the slope, the gear shift position of the target vehicle on the target uphill road is determined based on the preset rule. Further, according to the gear shift position and the engine torque, the target vehicle is downshifted on the slope based on the first preset downshift logic, and the corresponding downshift gear is determined. The first gear and the downshift gear are determined as the third gear of the target vehicle for downshifting on the slope.

[0099] It should be explained that the third gear is just a general term for the gear corresponding to the target vehicle passing the target uphill road when downshifting in the slope. In the actual climbing process, the third gear is not a constant value, but changes from the first gear to the downshift gear.

[0100] In addition, it should be noted that, when downshifting the target vehicle on a slope, a suitable shift position needs to be selected. When the target vehicle travels to the shift position at the target vehicle speed, the gear is switched to the downshift position.

[0101] Specifically, some logic or conditions are pre-set in the vehicle control system to determine when and where to perform the gear shift operation. The vehicle control system will calculate the most appropriate position for the gear shift on the target uphill road based on these logic or conditions, which may be based on factors such as the change in slope, the speed of the target vehicle, and the engine load.

[0102] For example, the most suitable shift position can be found by an optimization method. When finding the shift position by an optimization method, it is necessary to clearly define the optimization goal, for example, the goal may be to minimize fuel consumption, maximize the acceleration of the target vehicle, or keep the engine running in an efficient range, etc. Furthermore, the objective function needs to be able to quantify these goals so that optimization can be performed through calculation to find the most suitable shift position.

[0103] S103, calculating the energy consumption of the target vehicle when passing through the target uphill road according to each climbing gear.

[0104] Specifically, the energy consumption of the target vehicle when passing through the target uphill road in the first gear, the second gear, and the third gear is calculated respectively.

[0105] S104. Determine a target climbing gear based on the climbing gear according to the energy consumption corresponding to each climbing gear, so that the target vehicle climbs based on the target climbing gear.

[0106] In a possible implementation, the energy consumptions corresponding to the climbing gears are sorted in ascending order, and the climbing gear that ranks first is determined as the target climbing gear.

[0107] Explanatoryally, the energy consumption generated by the target vehicle passing the target uphill road in the first gear can be determined as the first energy consumption, the energy consumption generated by the target vehicle passing the target uphill road in the second gear can be determined as the second energy consumption, and the energy consumption generated by the target vehicle passing the target uphill road in the third gear can be determined as the third energy consumption.

[0108] Furthermore, the first energy consumption, the second energy consumption, and the third energy consumption are sorted in ascending order, and the gear corresponding to the lowest energy consumption, that is, the energy consumption ranked first, is determined as the target climbing gear.

[0109] It should be noted that the above process is implemented when the target vehicle can pass the target uphill road. However, if the target vehicle cannot pass the target uphill road with the target gear, it is also necessary to downshift the target vehicle to ensure that the target vehicle can eventually pass the target uphill road.

[0110] Specifically, if the target vehicle cannot pass the target uphill road at the target gear position, a second downshift operation is performed on the target vehicle based on the second preset downshift logic, and the climbing gear position after the downshift is determined. If the target vehicle cannot pass the target uphill road at the climbing gear position after the downshift, the second downshift operation is continued to be performed on the target vehicle based on the second preset downshift logic until the target vehicle passes the target uphill road at the climbing gear position after the downshift.

[0111] The vehicle shifting method for uphill roads provided by the present application obtains the road information parameters of the target uphill road and the vehicle information parameters of the target vehicle in advance before the target vehicle starts to climb. Among them, the target vehicle represents the vehicle that is about to travel on the target uphill road, and the road information parameters and vehicle information parameters obtained in advance provide a basis for optimizing the climbing gear of the target vehicle. Further, the target gear included in the vehicle information parameters is determined, and according to the road information parameters and the vehicle information parameters, it is judged based on a preset algorithm whether the target vehicle can pass the target uphill road with the target gear. If the target vehicle can pass the target uphill road with the target gear, the target gear is determined as the first gear. Afterwards, the target vehicle is downshifted to obtain the second gear after downshifting before the slope, and the third gear after downshifting in the slope. At this point, the climbing gears that the target vehicle can pass through the target uphill road, namely the first gear, the second gear and the third gear, have been obtained. Next, the energy consumption generated by the target vehicle passing through the target uphill road according to each climbing gear is calculated, and the energy consumption is sorted in ascending order by comparing the energy consumption corresponding to different climbing gears. The first climbing gear is determined as the target climbing gear, and the target vehicle will climb the slope in the target climbing gear. This process is intended to minimize the energy consumption of the target vehicle during the climbing process while ensuring that the target vehicle can climb the slope smoothly.

[0112] Next, a specific embodiment is used to Figure 1 The specific process of the vehicle shifting method for an uphill road shown is summarized. Figure 2 The process diagram of the vehicle shifting method for an uphill road provided in this application is as follows Figure 2 ,like Figure 2 As shown, the vehicle shifting method facing an uphill road specifically includes the following steps:

[0113] S201, obtaining road information parameters of a target uphill road;

[0114] S202, obtaining vehicle information parameters of a target vehicle that is about to travel on a target uphill road;

[0115] S203, determining a target gear position included in the vehicle information parameters; wherein the target gear position represents the gear position when the target vehicle travels to the bottom of the target uphill road;

[0121] S208, performing a downshift operation before a slope or during a slope on the target vehicle based on the engine torque;

[0122] Explanatory, the above engine torque can be obtained by analyzing the throttle opening when the target vehicle reaches the bottom of the target uphill road. It should be noted that downshifting the target vehicle based on the engine torque is only one possible implementation method. In addition, the target vehicle can also be downshifted based on the speed of the target vehicle when it reaches the bottom of the target uphill road. The speed of the target vehicle when it reaches the bottom of the slope can also be obtained by analyzing the throttle opening. How to downshift the target vehicle can be determined according to actual needs and is not specifically limited here.
