Detailed Description
Embodiments of the present application are described below with reference to the accompanying drawings.
How to make users have a better driving experience has been a major concern for those skilled in the automotive arts. In the related art, the change of the vehicle speed is mainly realized by actively driving the cylinder in the oil cylinder, for example, when the user wants to accelerate the running, the vehicle speed can be increased by reducing the pressure of the actively driving cylinder. However, because the pressure adjustment range of the active driving cylinder is limited, a relatively stable acceleration experience can be provided for the user, and when the user wants to accelerate to a relatively large extent, the driving requirement of the user is difficult to meet only by the active driving cylinder.
In order to solve the technical problem, the application provides a vehicle control method, and a processing device can determine a corresponding speed change intention based on vehicle running information corresponding to a target vehicle, wherein the speed change intention can reflect the vehicle speed adjustment requirement of a user. Based on the speed change intention, the processing equipment can select the driving cylinder or the combination of the driving cylinder and the driven driving cylinder to adjust the speed of the vehicle, so that various speed adjusting modes are provided for the user, different speed adjusting requirements of the user are met, and the driving experience of the user is improved.
It will be appreciated that the method may be applied to a processing device, which is a processing device having a vehicle control function, for example, a terminal device or a server having a vehicle control function. The method can be independently operated by the terminal equipment, can also be applied to a network scene of communication between the terminal equipment and the server, and is operated by the cooperation of the terminal equipment and the server. The terminal device may be a vehicle-mounted computer, a Personal Digital Assistant (PDA) DIGITAL ASSISTANT, a vehicle-mounted tablet computer, or the like. The server can be understood as an application server or a Web server, and in actual deployment, the server can be an independent physical server or a server cluster or a distributed system formed by a plurality of physical servers. The terminal and the server may be directly or indirectly connected through wired or wireless communication, and the present application is not limited herein.
Next, a vehicle control method according to an embodiment of the present application will be described with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a vehicle control method according to an embodiment of the present application, where the method includes:
S101, acquiring vehicle running information corresponding to a target vehicle.
In order to learn the current driving intention of the user during the driving of the vehicle by the user, the processing device first needs to acquire information that can be used to determine the driving intention of the user. It can be appreciated that the control of the vehicle by the user during driving of the vehicle can be represented in vehicle driving information, which refers to various information related to vehicle driving, for example, in one possible implementation manner, the vehicle driving information may include any one or more of vehicle speed information, accelerator pedal force and accelerator pedal amplitude, where the vehicle speed information can represent the vehicle speed of the target vehicle during driving, and the accelerator pedal force and the accelerator pedal amplitude can reflect the control intention of the user on the vehicle speed during driving, and indicate that the greater the accelerator pedal force or the greater the accelerator pedal amplitude, the greater the acceleration force required by the user at the moment, and the smaller the accelerator pedal force or the smaller the accelerator pedal amplitude, the smaller the acceleration force required by the user at the moment. Thus, the driving intention of the user can be reflected to some extent by the vehicle travel information.
S102, determining the corresponding speed change intention of the target vehicle according to the vehicle running information.
After acquiring the vehicle running information corresponding to the target vehicle, the processing device may determine, according to the vehicle running information, a speed change intention corresponding to the target vehicle, the speed change intention being used to reflect a change in the vehicle speed required by the user when driving the target vehicle. For example, when the vehicle traveling information includes an accelerator pedal force, if the accelerator pedal force exceeds a certain preset value, which indicates that the user wants to increase the vehicle speed more severely at this time, the processing device may determine that the speed change corresponding to the target vehicle at this time is intended to be a speed change that is more rapid. By determining the speed change intention, the processing device can accurately acquire the requirement of the user and correspondingly control the vehicle based on the requirement.
S103, determining a target oil cylinder for adjusting the vehicle speed according to the speed change intention.
In order to meet different control demands of users on vehicle speed, after determining the speed change intention, the processing device also needs to be capable of correspondingly adjusting the vehicle speed according to the speed change intention. As described above, since the pressure regulating range of the actively driven cylinder in the vehicle is limited, the regulation can be completed by the actively driven cylinder itself when the speed change intention is a more gentle change intention, however, it may be difficult to satisfy the speed regulating requirement of the user only by the actively driven cylinder when the speed change intention is a more severe change intention. Therefore, in order to provide a better speed adjustment experience for the user, in the embodiment of the application, the processing device can adjust the target vehicle through the combination of the driving cylinder and the driven cylinder in addition to the speed adjustment through the driving cylinder. For example, when the speed change is intended to be a more severe change, in order to provide a user with a sufficient speed change amount, the processing device may reduce the pressure of the driving cylinder and simultaneously increase the pressure of the driven cylinder, so as to further increase the speed ratio of the target vehicle, and finally reduce the time required for increasing the speed of the target vehicle, thereby bringing a better speed change experience to the user. Thus, in embodiments of the present application, the target cylinder may include a master cylinder, or a combination of a master cylinder and a slave cylinder.
And S104, adjusting the speed of the target vehicle based on the target oil cylinder.
After the target oil cylinder is determined, the processing equipment can adjust various vehicle speeds of the target vehicle by adjusting the pressure value of the target oil cylinder.
According to the technical scheme, the vehicle control method provided by the embodiment of the application can be used for firstly acquiring the vehicle running information corresponding to the target vehicle in the process of driving the target vehicle by a user, determining the speed change intention corresponding to the target vehicle according to the vehicle running information, and reflecting the driving requirement of the user on the target vehicle to a certain extent. In order to enable the speed change of the target vehicle to meet the driving requirement of a user, a target oil cylinder for adjusting the vehicle speed can be determined according to the speed change intention, wherein the target oil cylinder comprises a driving cylinder or a combination of the driving cylinder and a driven driving cylinder. After the target oil cylinder is determined, the speed of the target vehicle can be adjusted based on the target oil cylinder, so that when the speed of the vehicle is adjusted, different speed adjusting requirements can be met through the combination of multiple oil cylinders, multiple speed changing modes are provided for a user, and the driving experience of the user is improved.
In order to accurately judge the driving intention of the user, the processing device may set a plurality of speed change intents according to actual demands when determining the speed change intention according to the vehicle running information. For example, in one possible implementation, the speed change intent may include any of a low-level acceleration intent that indicates that the user requires smoother, lower magnitude vehicle acceleration at this time, a medium-level acceleration intent that indicates that the user requires more rapid, higher magnitude vehicle acceleration at this time, and a high-level acceleration intent that indicates that the user requires a more intense vehicle acceleration experience based on the medium-level acceleration intent. For example, when the user steps on the accelerator force is small, the processing device may determine that the speed change intention at this time is a low-level acceleration intention, and when the user steps on the accelerator force is large, the processing device may determine that the speed change intention at this time is a medium-level acceleration intention or a high-level acceleration intention. When the specific judgment is carried out, the processing equipment can set corresponding accelerator values or vehicle speed values for different acceleration intents, and after the corresponding accelerator values or vehicle speed values are reached, the processing equipment can determine the corresponding acceleration intents.
If the speed change intention is determined to be a low-level acceleration intention, the acceleration experience required by the user is mild, and the acceleration effect can be met by driving the cylinder under normal conditions, so that the processing equipment can determine that the target oil cylinder is the driving cylinder, and if the speed change intention is determined to be a medium-level acceleration intention or a high-level acceleration intention, the acceleration experience required by the user is severe, the processing equipment can determine that the target oil cylinder is a combination of driven cylinders of the driving cylinder, so that the acceleration capability with larger amplitude and quicker speed is provided for the target vehicle.
Specifically, in the process of adjusting the vehicle speed of the target vehicle, the adjustment mode of the processing device may be different for different target cylinders. In one possible implementation, if the target cylinder is determined to be a driving cylinder, the processing device may adjust the target vehicle by reducing the pressure of the driving cylinder, and if the target cylinder is determined to be a combination of the driving cylinder and a driven cylinder, the processing device may adjust the vehicle speed of the target vehicle by reducing the pressure of the driving cylinder and further increasing the pressure of the driven cylinder in addition to the driving effect of the driving cylinder. It can be understood that, because the metal belt for connecting transmission is arranged between the driving cylinder and the driven driving cylinder, under the transmission action of the metal belt, when the driving cylinder is depressurized, the driven driving cylinder is driven to be pressurized. Therefore, it is worth noting that in order to further improve the speed increasing amplitude of the target vehicle, the embodiment of the application further increases the pressure of the driven driving cylinder besides the driving effect of the driving cylinder, thereby realizing additional adjustment of the vehicle speed and meeting the more drastic speed increasing requirement of a user.
When the vehicle speed is adjusted by the combination of the driving cylinder and the driven driving cylinder, the range of pressurizing the driven driving cylinder may be different according to different actual requirements. For example, in one possible implementation, if it is determined that the speed change is intended to be a medium-level acceleration intention, the processing apparatus further increases the pressure of the driven driving cylinder in addition to the driving action of the driving cylinder while reducing the pressure of the driving cylinder, where the allowable supercharging value corresponding to the driven driving cylinder is smaller than the maximum value of the pressure corresponding to the driven driving cylinder. Wherein the pressure boost allowable value refers to a pressure value which is allowed to be increased by the processing equipment in the process of boosting the driven driving cylinder, the maximum pressure value refers to the maximum pressure value that the slave cylinder itself can grow.
If the speed change intention is determined to be an advanced acceleration intention, the processing equipment can further increase the pressure of the driven driving cylinder besides the driving effect of the driving cylinder while reducing the pressure of the driving cylinder, and the pressure allowable value corresponding to the driven driving cylinder does not exceed the pressure maximum value corresponding to the driven driving cylinder. By this setting, when the speed change intention is a high-level acceleration intention, the pressure of the slave cylinder can be further increased, and the speed change rate of the target vehicle can be further increased.
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 described below with reference to an actual application scenario. In the actual application scenario, the processing device may be a vehicle-mounted terminal, and the vehicle-mounted terminal may acquire running data of the target vehicle in real time and regulate and control the target vehicle.
In the process of driving the target vehicle by the user, the vehicle-mounted terminal can monitor and collect the current running speed of the vehicle and the amplitude of stepping on the accelerator by the user in real time. The vehicle-mounted terminal can set a preset threshold value for the vehicle speed and the accelerator pedal amplitude, and determine the corresponding speed change intention of the target vehicle based on the preset threshold value,
When the speed change intention is a primary acceleration intention, the vehicle-mounted terminal can only adjust the vehicle speed by driving the cylinder, as shown in fig. 2, fig. 2 is a schematic diagram of a vehicle control method provided in the embodiment of the present application, and it can be seen from the figure that, when the primary acceleration intention is performed, the input shaft rotation speed and the speed ratio of the target vehicle are raised more slowly, the vehicle speed is raised at a more gentle speed, the pressure of the driving cylinder (i.e. the driving cylinder) is reduced, and the pressure of the driven cylinder (i.e. the driven cylinder) is increased.
When the speed change intention is a medium-grade acceleration intention, the vehicle-mounted terminal can perform vehicle speed adjustment through a combination of the driving cylinder and the driven cylinder, and the pressure of the driven cylinder is actively increased while the pressure of the driving cylinder is reduced, so that more speed adjustment power is provided for the vehicle. As shown in fig. 3, fig. 2 is a schematic diagram of a vehicle control method according to an embodiment of the present application, and it can be seen from the diagram that, when the intermediate-stage acceleration is intended, the input shaft speed and the speed ratio of the target vehicle are faster to increase, the pressure of the driving cylinder is reduced, and the pressure of the driven cylinder can be further increased under the driving action of the driving cylinder. Under the intention of medium-level acceleration, the vehicle-mounted terminal can limit the pressure boost allowable value of the pressure of the slave cylinder to be smaller than the corresponding pressure maximum value, so that fuel consumption is saved to a certain extent under the condition of improving the vehicle speed adjusting efficiency.
When the speed change intention is a high-grade acceleration intention, the vehicle-mounted terminal can further improve the pressure of the slave cylinder on the basis of the medium-grade acceleration intention, as shown in fig. 4, the pressure of the slave cylinder can be improved to the maximum value of the pressure corresponding to the slave cylinder, so that the speed ratio and the rotating speed of the input shaft can be improved to target values required by a user in the shortest time, and the strongest acceleration experience is brought to the user.
