[0043] The embodiments of the present application are described below in conjunction with the accompanying drawings.

[0044] How to make users have a better driving experience has always been a key issue of concern to relevant personnel in the automotive field. In related technologies, the change of vehicle speed is mainly achieved through the active drive cylinder in the oil cylinder. For example, when the user wants to accelerate, the vehicle speed can be increased by reducing the pressure of the active drive cylinder. However, due to the limited pressure adjustment range of the active drive cylinder, it can only provide users with a relatively smooth acceleration experience. When the user wants to accelerate with a large amplitude, it is difficult to meet the user's driving needs only by the active drive cylinder.

[0045] In order to solve the above technical problems, the present application provides a vehicle control method, in which a processing device can determine a corresponding speed change intention based on vehicle driving information corresponding to a target vehicle, and the speed change intention can reflect the user's vehicle speed adjustment needs. Based on the speed change intention, the processing device can select an active drive cylinder or a combination of an active drive cylinder and a driven drive cylinder to adjust the vehicle speed, thereby providing the user with a variety of vehicle speed adjustment methods, meeting the user's different vehicle speed adjustment needs, and improving the user's driving experience.

[0046] It is understandable that the method can be applied to a processing device, which is a processing device with a vehicle control function, for example, a terminal device or a server with a vehicle control function. The method can be run independently by a terminal device, or it can be applied to a network scenario in which a terminal device and a server communicate, and the terminal device and the server cooperate to run. Among them, the terminal device can be a vehicle-mounted computer, a personal digital assistant (PDA for short), a vehicle-mounted tablet computer and other devices. The server can be understood as an application server or a Web server. In actual deployment, the server can be an independent physical server or a server cluster or distributed system composed of multiple physical servers. The terminal and the server can be directly or indirectly connected via wired or wireless communication, and this application is not limited here.

[0047] Next, a vehicle control method provided in an embodiment of the present application will be introduced in conjunction with the accompanying drawings.

[0048] See also Figure 1 , Figure 1 A flow chart of a vehicle control method provided in an embodiment of the present application, the method comprising:

[0049] S101: Obtain vehicle driving information corresponding to a target vehicle.

[0050] In the process of the user driving the vehicle, in order to know the user's current driving intention, the processing device first needs to obtain information that can be used to determine the user's driving intention. It can be understood that the user's control of the vehicle in the process of driving the vehicle can be reflected in the vehicle driving information, and the vehicle driving information refers to various types of information related to the vehicle driving. For example, in a possible implementation, the vehicle driving information can include any one or more combinations of vehicle speed information, accelerator pedaling force, and accelerator pedaling amplitude. The vehicle speed information can reflect the speed of the target vehicle during driving, and the accelerator pedaling force and accelerator pedaling amplitude can reflect the user's control intention of the vehicle speed during driving. The greater the accelerator pedaling force or the greater the accelerator pedaling amplitude, the greater the acceleration force required by the user at this time; the smaller the accelerator pedaling force or the smaller the accelerator pedaling amplitude, the smaller the acceleration force required by the user at this time. It can be seen that through the vehicle driving information, the user's driving intention can be reflected to a certain extent.

[0051] S102: Determine the speed change intention corresponding to the target vehicle according to the vehicle driving information.

[0052] After obtaining the vehicle driving information corresponding to the target vehicle, the processing device can determine the speed change intention corresponding to the target vehicle based on the vehicle driving information, and the speed change intention is used to reflect the speed change required by the user when driving the target vehicle. For example, when the vehicle driving information includes the accelerator pedal force, if the accelerator pedal force exceeds a preset value, it means that the user wants to increase the speed more drastically at this time, then the processing device can determine that the speed change intention corresponding to the target vehicle at this time is a more rapid speed change. By determining the speed change intention, the processing device can more accurately know the user's needs and control the vehicle accordingly based on the needs.

[0053] S103: Determine a target cylinder for adjusting the vehicle speed according to the speed change intention.

[0054] In order to meet the different control requirements of the user for the vehicle speed, after determining the speed change intention, the processing device also needs to be able to adjust the vehicle speed accordingly according to the speed change intention. As mentioned above, due to the limited pressure adjustment range of the active drive cylinder in the vehicle, when the speed change intention is a relatively gentle change intention, the adjustment can be completed by the active drive cylinder itself; however, when the speed change intention is a more drastic change intention, it may be difficult to meet the user's speed adjustment needs only by the active drive cylinder. Therefore, in order to provide users with a better speed adjustment experience, in the embodiment of the present application, in addition to being able to adjust the vehicle speed through the active drive cylinder, the processing device can also adjust the target vehicle through a combination of the active drive cylinder and the driven drive cylinder. For example, when the speed change intention is a more drastic change, in order to provide the user with sufficient speed change, the processing device can reduce the pressure of the active drive cylinder while actively increasing the pressure of the driven drive cylinder, thereby further improving the speed ratio of the target vehicle, and ultimately reducing the time required to increase the speed of the target vehicle, bringing users a better speed change experience. Therefore, in the embodiment of the present application, the target oil cylinder can include an active drive cylinder, or a combination of an active drive cylinder and a driven drive cylinder.

[0055] S104: Based on the target cylinder, the speed of the target vehicle is adjusted.

[0056] After determining the target cylinder, the processing device can adjust the pressure value of the target cylinder to achieve various speed adjustments for the target vehicle.

[0057] It can be seen from the above technical scheme that the embodiment of the present application provides a vehicle control method. When the user drives the target vehicle, the vehicle driving information corresponding to the target vehicle can be obtained first. According to the vehicle driving information, the speed change intention corresponding to the target vehicle can be determined. The speed change intention can reflect the user's driving needs for the target vehicle to a certain extent. In order to make the speed change of the target vehicle fit the user's driving needs, the target cylinder for speed adjustment can be determined according to the speed change intention. The target cylinder includes an active drive cylinder or a combination of the active drive cylinder and a driven drive cylinder. After the target cylinder is determined, the speed of the target vehicle can be adjusted based on the target cylinder, so that when adjusting the speed, different speed adjustment needs can be met through a variety of cylinder combinations, providing users with a variety of speed change modes and improving the user's driving experience.

[0058] In order to accurately judge the user's driving intention, when determining the speed change intention according to the vehicle driving information, the processing device can set multiple speed change intentions according to actual needs. For example, in a possible implementation, the speed change intention can include any one of a low-level acceleration intention, a medium-level acceleration intention, and a high-level acceleration intention. The low-level acceleration intention indicates that the user needs a relatively stable and low-amplitude vehicle acceleration at this time, the medium-level acceleration intention indicates that the user needs a relatively rapid and high-amplitude vehicle acceleration at this time, and the high-level acceleration intention indicates that the user needs a more intense vehicle acceleration experience on the basis of the medium-level acceleration intention. For example, when the user steps on the accelerator with less force, the processing device can determine that the speed change intention at this time is a low-level acceleration intention; when the user steps on the accelerator with greater force, the processing device can determine that the speed change intention at this time is a medium-level acceleration intention or a high-level acceleration intention. In specific judgment, the processing device can set corresponding throttle values ​​or vehicle speed values ​​for different acceleration intentions, and after reaching the value, the processing device can determine the corresponding acceleration intention.

[0059] If it is determined that the speed change intention is a low-level acceleration intention, the acceleration experience required by the user is relatively gentle, which can usually be satisfied by the active driving cylinder. Therefore, the processing device can determine that the target cylinder is an active driving cylinder; if it is determined that the speed change intention is an intermediate acceleration intention or a high-level acceleration intention, the acceleration experience required by the user is relatively drastic. The processing device can determine that the target cylinder is a combination of an active driving cylinder and a slave driving cylinder, thereby providing the target vehicle with a larger and faster acceleration capability.

[0060] Specifically, in the process of adjusting the speed of the target vehicle, the adjustment method of the processing device may be different for different target cylinders. In a possible implementation, if the target cylinder is determined to be an active drive cylinder, the processing device can adjust the target vehicle by reducing the pressure of the active drive cylinder; if the target cylinder is determined to be a combination of an active drive cylinder and a driven drive cylinder, the processing device can adjust the speed of the target vehicle by reducing the pressure of the active drive cylinder and further increasing the pressure of the driven drive cylinder in addition to the driving effect of the active drive cylinder. It can be understood that since there is a metal belt for connecting the transmission between the active drive cylinder and the driven drive cylinder, under the transmission effect of the metal belt, when the active drive cylinder is depressurized, the driven drive cylinder will be driven to increase the pressure. Therefore, it is worth noting that in order to further increase the speed increase amplitude of the target vehicle, the embodiment of the present application further increases the pressure of the driven drive cylinder in addition to the driving effect of the active drive cylinder, thereby realizing additional adjustment of the vehicle speed and meeting the user's more intense speed increase needs.

[0061] Among them, when it is necessary to adjust the vehicle speed through the combination of the active drive cylinder and the driven drive cylinder, the amplitude of the boost to the driven drive cylinder may also be different according to different actual needs. For example, in one possible implementation, if it is determined that the speed change intention is a mid-level acceleration intention, the processing device reduces the pressure of the active drive cylinder while further increasing the pressure of the driven drive cylinder in addition to the driving effect of the active drive cylinder, and the boost allowable value corresponding to the driven drive cylinder is less than the maximum pressure corresponding to the driven drive cylinder. Among them, the boost allowable value refers to the pressure value allowed to increase by the processing device in the process of boosting the driven drive cylinder, and the maximum pressure refers to the maximum pressure value that the driven drive cylinder itself can increase.

[0062] If the speed change intention is determined to be a high-level acceleration intention, while reducing the pressure of the active driving cylinder, the processing device can further increase the pressure of the slave driving cylinder in addition to the driving effect of the active driving cylinder, and the corresponding pressure increase allowable value of the slave driving cylinder does not exceed the corresponding maximum pressure of the slave driving cylinder. Through this setting, when the speed change intention is a high-level acceleration intention, the pressure of the slave driving cylinder can be further increased, thereby further improving the speed change rate of the target vehicle.

[0063] In order to facilitate understanding of the technical solution of the embodiment of the present application, a vehicle control method provided by the embodiment of the present application will be introduced below in combination with an actual application scenario. In the actual application scenario, the processing device may be a vehicle-mounted terminal, which can obtain the driving data of the target vehicle in real time and regulate the target vehicle.

[0064] When the user is driving the target vehicle, the vehicle terminal can monitor and collect the current speed of the vehicle and the amplitude of the user's accelerator pedal in real time. The vehicle terminal can set preset thresholds for the vehicle speed and the amplitude of the accelerator pedal pedal, and determine the speed change intention of the target vehicle based on the preset thresholds.

[0065] When the speed change intention is a primary acceleration intention, the vehicle terminal can adjust the vehicle speed only by actively driving the cylinder, such as Figure 2 As shown, Figure 2 A schematic diagram of a vehicle control method provided in an embodiment of the present application. As can be seen from the figure, when the primary acceleration intention is present, the input shaft speed and speed ratio of the target vehicle increase relatively slowly, the vehicle speed increases at a relatively gentle rate, the pressure of the active cylinder (i.e., the active driving cylinder) decreases, and the pressure of the driven cylinder (i.e., the driven driving cylinder) increases.

[0066] When the speed change intention is a medium acceleration intention, the vehicle terminal can adjust the vehicle speed through the combination of the active cylinder and the slave cylinder, actively increasing the slave cylinder pressure while reducing the active cylinder pressure, thereby providing more speed adjustment power for the vehicle. Figure 3As shown, Figure 2 This is a schematic diagram of a vehicle control method provided by an embodiment of the present application. As can be seen from the figure, when the intermediate acceleration intention is present, the input shaft speed and speed ratio of the target vehicle are increased relatively quickly, and while the pressure of the active cylinder is reduced, the slave cylinder can further increase the pressure in addition to the driving effect of the active cylinder. Under the intermediate acceleration intention, the vehicle-mounted terminal can limit the boost allowable value of the pressure of the slave cylinder to be less than the corresponding maximum pressure, thereby saving fuel consumption to a certain extent while improving the vehicle speed regulation efficiency.

[0067] When the speed change intention is a high-level acceleration intention, the vehicle terminal can further increase the pressure of the slave cylinder based on the intermediate acceleration intention, such as Figure 4 As shown, at this time, the pressure of the slave cylinder can be increased to the maximum pressure corresponding to the slave cylinder, so that the speed ratio and the input shaft speed can be increased to the target values ​​required by the user in the shortest time, giving the user the most intense speed-up experience.
