Technical Field
[0001] The present application belongs to the field of vehicle technology, and in particular, relates to a vehicle control method, device, electronic device and storage medium. Background Art
[0002] The current range anxiety of electric vehicles has greatly restricted the development of electric vehicles, especially on high-speed and long-distance roads. As the vehicle speed increases, the increase in wind resistance and the decrease in motor efficiency will lead to rapid consumption of battery energy, thereby significantly shortening the driving range.
[0003] In related technologies, the improvement of driving range is mainly achieved by reducing the vehicle's wind resistance coefficient, reducing the power of electronic equipment, reducing vehicle weight, energy recovery, etc. However, these measures often reduce comfort while improving driving range. Summary of the invention

The embodiment of the present application obtains the vehicle speed and tire pressure of the vehicle during driving. If the vehicle speed is high, the vehicle speed is obtained again after a period of time, and the tire pressure is actively increased when the vehicle speed is stable above the first preset value to reduce the rolling resistance of the wheel and improve the cruising range of the vehicle. Moreover, since the increase in tire pressure is performed after the vehicle speed is stable, the energy waste and the problem of reduced comfort caused by frequent adjustment of tire pressure when the vehicle speed fluctuates around the first preset value are avoided, thereby improving the cruising range of the vehicle while reducing the reduction in comfort to a certain extent.

This allows the user to directly participate in the vehicle performance optimization process and customize the matching scheme of tire pressure and vehicle speed according to actual driving conditions and expected driving efficiency. This not only improves the vehicle's energy efficiency and extends the endurance, but also meets the user's personalized requirements for vehicle performance.
[0023] According to one embodiment of the present application, the method further includes:

[0026] In this embodiment, the vehicle speed and tire pressure are obtained during driving. If the vehicle speed is low, the vehicle speed is obtained again after a period of time. When the vehicle speed stabilizes below a first preset value, the tire pressure is actively reduced to increase the contact area between the tire and the ground and improve vehicle comfort.

If the vehicle speed is high, the vehicle speed is obtained again after a period of time, and the tire pressure is actively increased when the vehicle speed is stable above the first preset value to reduce the rolling resistance of the wheel and improve the cruising range of the vehicle. Moreover, since the increase in tire pressure is performed after the vehicle speed is stable, the energy waste and the problem of reduced comfort caused by frequent adjustment of tire pressure when the vehicle speed fluctuates around the first preset value are avoided, thereby improving the cruising range of the vehicle while reducing the reduction in comfort to a certain extent.

[0051] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0052] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0053] The range of an electric vehicle is the maximum distance that an electric vehicle can travel after a single full charge, usually measured in kilometers (km). This distance is affected by many factors, including battery capacity, vehicle aerodynamic design, vehicle weight, tire rolling resistance, road conditions, climate conditions, driving habits, and vehicle energy efficiency. The current range anxiety of electric vehicles has largely restricted the development of electric vehicles, especially on high-speed long-distance sections. As the speed increases, wind resistance and motor efficiency will decrease, resulting in a significant reduction in the range of electric vehicles.
[0054] In related technologies, the improvement of driving range is mainly achieved by reducing the vehicle's wind resistance coefficient, reducing the power of electronic equipment, reducing vehicle weight, energy recovery, etc. However, these measures often lead to a reduction in comfort.
[0055] The drag coefficient is an indicator that measures the impact of air resistance on a vehicle during driving. When a vehicle is driving at high speed, air resistance will increase significantly, resulting in increased energy consumption. Reducing the vehicle's drag coefficient can be achieved by optimizing the vehicle's appearance design, such as a more streamlined body, flattening the chassis, and using an aerodynamic kit.
[0056] Electronic devices include the vehicle's entertainment system, air conditioning, lighting, etc. The power consumption of these devices will occupy a part of the electrical energy. Reducing the power of electronic devices can be achieved by using more efficient electronic components, optimizing energy management systems, and reducing unnecessary energy consumption.
[0057] The weight of a vehicle directly affects energy consumption. The lighter the weight, the less energy is required to drive. The weight of a vehicle can be reduced by using lightweight materials (such as aluminum alloy, carbon fiber, etc.), optimizing structural design, and reducing unnecessary accessories.
[0058] Energy recovery systems (such as regenerative braking systems) can recover part of the kinetic energy when the vehicle decelerates or brakes, converting it back into electrical energy and storing it in the battery. By optimizing the energy recovery strategy and improving the recovery efficiency, the energy utilization efficiency of electric vehicles can be improved and the driving range can be increased.
[0059] However, improving the driving range through the above measures often leads to a reduction in comfort. For example, reducing the vehicle's drag coefficient may affect the vehicle's interior space, thereby reducing comfort; excessive restrictions on the use of electronic devices may reduce driving and riding comfort; weight reduction may sacrifice some vehicle stability, safety and comfort, and the energy recovery system will affect driving smoothness, resulting in reduced comfort.
[0060] After research, the present applicant found that tire pressure will have a certain impact on vehicle endurance. If the tire pressure is too low, the contact area between the tire and the ground will increase, thereby increasing friction, causing the car to require more energy to move forward, thereby increasing energy consumption and reducing endurance. If the tire pressure is too high, although it can reduce rolling resistance and increase endurance to a certain extent, it will also increase tire wear, especially when driving at high speeds. Excessive tire pressure will reduce ride comfort and may also cause the tire to burst due to pressure.
[0061] The present application takes into account that if an active tire pressure control strategy can be used, the vehicle resistance can be reduced by increasing the tire pressure when the vehicle is traveling at high speed, thereby reducing energy consumption and improving endurance, and the vehicle speed can be monitored before adjusting the tire pressure, and the tire pressure can be adjusted after the vehicle speed stabilizes. This is expected to solve the problem of reduced ride comfort in order to improve the endurance of electric vehicles in the prior art.
[0062] The vehicle control method, device, electronic device and storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.
[0063] Among them, the vehicle control method can be applied to a terminal, and can be specifically executed by hardware or software in the terminal.
[0064] The terminal includes, but is not limited to, a portable communication device such as a mobile phone or tablet computer with a touch-sensitive surface (e.g., a touch screen display and / or a touch pad). It should also be understood that in some embodiments, the terminal may not be a portable communication device, but a desktop computer with a touch-sensitive surface (e.g., a touch screen display and / or a touch pad).
[0065] In the following various embodiments, a terminal including a display and a touch-sensitive surface is described. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, a mouse and a joystick.
[0066] The vehicle control method provided in the embodiment of the present application may be executed by an electronic device or a functional module or functional entity in the electronic device that can implement the vehicle control method. The electronic devices mentioned in the embodiment of the present application include but are not limited to mobile phones, tablet computers, computers, cameras, wearable devices, electronic control units (Electronic Control Unit, ECU), MCU (Microcontroller Unit) or other controllers, etc. The vehicle control method provided in the embodiment of the present application is described below using an electronic device as an example of the execution subject.
[0067] like Figure 1 As shown, the vehicle control method includes: step 110, step 120 and step 130.
[0068] Step 110: When the endurance assistance function is turned on, obtain the first vehicle speed and tire pressure value of the vehicle during driving.
[0069] In the embodiment of the present application, the range assist function may be a functional module provided by the vehicle that helps improve the range, and when the range assist function is turned on, the range improvement control is performed. The range assist function may be turned on by default, or it may be manually triggered to turn on by the user. Of course, it may also be turned on in any other way, such as automatically turning on when the vehicle speed reaches a certain value, or when the vehicle's energy consumption exceeds a certain value. Technicians in this field may set it according to actual conditions, and the embodiment of the present application is symmetric and not limited.
[0070] The full name of tire pressure is tire pressure, which refers to the pressure of the air inside the tire. It is an indicator to measure the air pressure inside the tire. Tire pressure will affect the performance of the vehicle. When the tire pressure is too low, it will increase the friction between the tire and the ground, causing the vehicle to consume more energy to push the tire to rotate, which will reduce the vehicle's endurance. When the tire pressure is increased, although it can reduce the friction between the tire and the ground and improve the endurance, it may reduce the shock absorption performance of the vehicle, causing a bumpy ride and reducing the ride comfort.
[0071] The vehicle speed can be obtained through the wheel speed sensor on the wheel during driving. The wheel speed sensor is generally installed near the wheel to monitor the rotation speed of each wheel in real time. The vehicle speed can be calculated based on the average rotation speed of the four wheels. For example, the front left wheel speed Vfl, the front right wheel speed Vfr, the rear left wheel speed Vrl, and the rear right wheel speed Vrr are measured by the wheel speed sensor, then the vehicle speed Vm = (Vfl + Vfr + Vrl + Vrr) / 4.
[0072] The tire pressure of the vehicle can be obtained by a tire pressure sensor installed on the tire during driving. In the embodiment of the present application, the vehicle speed and tire pressure are obtained in real time by the wheel speed sensor and the tire pressure sensor, and recorded and determined as the first vehicle speed and tire pressure value.
[0073] Step 120: When the first vehicle speed is greater than or equal to the first preset value, if the tire pressure value is less than the first preset range or is within the first preset range, obtain the second vehicle speed of the vehicle after the first preset time.
[0074] The tire pressure values recommended by most vehicle manufacturers are usually between 220kpa and 320kpa, depending on the load and tire specifications of the vehicle. In the embodiment of the present application, different vehicle speeds can be matched with different tire pressure values, such as low vehicle speeds corresponding to lower tire pressures, such as a tire pressure of 250kpa corresponding to a vehicle speed below 90km / h, to improve the ride comfort of the vehicle, and high vehicle speeds can correspond to high tire pressures, such as a tire pressure of 290kpa corresponding to a vehicle speed of 90km / h and above, thereby improving the vehicle's endurance. Of course, the correspondence between vehicle speed and tire pressure can also include other situations, such as a first lower vehicle speed range corresponding to a lower tire pressure range, such as a vehicle speed of 60-90km / h corresponding to a tire pressure of 240-260kpa, and a vehicle speed of 90-120km / h corresponding to a tire pressure of 280-300kpa. This application does not limit the specific correspondence between vehicle speed and tire pressure.
[0075] In this embodiment, the first preset value may be a critical value for dividing the vehicle speed into high speed or low speed, for example, the first preset value may be 85km / h, 90km / h, 95km / h, etc., or other values. The first preset range may be a basis for dividing the tire pressure value, and the first preset range may be 235kpa-240kpa, 240kpa-255kpa, etc., or other ranges. Those skilled in the art may set the first preset value and the first preset range according to actual conditions, and the embodiment of the present application does not limit this.
[0076] When the first vehicle speed is greater than or equal to the first preset value, it means that the vehicle is currently driving at a high speed. In this case, the tire pressure value needs to be increased to a certain range to improve the vehicle's endurance. When the tire pressure value is less than the first preset range or is within the first preset range, it means that the tire pressure value is too small and needs to be increased.
[0077] However, due to factors such as the road environment on which the vehicle is traveling, the vehicle speed may change continuously. When the vehicle speed is greater than or equal to the first preset value, if the tire pressure is less than the first preset range or is within the first preset range, if the tire pressure is adjusted immediately, the vehicle speed may be less than the first preset value again within a very short period of time, and the tire pressure must be lowered again, resulting in too frequent adjustments of the tire pressure, which wastes energy and reduces ride comfort.
[0078] In an embodiment of the present application, in order to reduce the situation where the tire pressure keeps changing when the vehicle speed fluctuates around a preset value, a first preset time can be set. When the first vehicle speed is greater than or equal to the first preset value, if the tire pressure is less than the first preset range or is within the first preset range, the second vehicle speed is obtained after the first preset time, and whether the vehicle speed is stable is determined based on whether the second vehicle speed is still greater than or equal to the first preset value, and the tire pressure is adjusted when the vehicle speed is stable.
[0079] Step 130: When the second vehicle speed is greater than or equal to the first preset value, the tire pressure value is increased to a second preset range so that the tire pressure value of the vehicle matches the vehicle speed.
[0080] In the embodiment of the present application, if the second vehicle speed after the first preset time is still greater than or equal to the first preset value, it means that the vehicle speed has stabilized above the first preset value. In this case, the wheel inflation can be controlled to increase the tire pressure value to the second preset range. Among them, the first preset time can be 2s, 3s, 5s, etc., and those skilled in the art can set different values according to actual conditions, and the embodiment of the present application does not limit this. The minimum value of the second preset range is greater than the maximum value of the first preset range. The second preset range can be 285kpa-290kpa, 290kpa-300kpa, etc., and those skilled in the art can set the second preset range according to actual conditions, and the embodiment of the present application does not limit this.
[0081] In the embodiment of the present application, the tire pressure can be adjusted by driving an air pump driven by a motor to inflate and deflate the tire. Figure 2As shown, the ECU can receive the wheel speed sent by the wheel speed sensor, and the tire pressure value sent by the tire pressure sensor, and calculate whether the first vehicle speed matches the tire pressure value based on the data sent by the wheel speed sensor and the tire pressure sensor. If they do not match, the tire pressure of the vehicle is adjusted. When the tire pressure needs to be increased, the ECU will send a command to the control box. After receiving the command from the ECU, the control box opens the corresponding valve, and the air pump starts working to compress the air and transport it to the tire through a pipe to inflate the tire. During this process, the ECU continuously monitors the tire pressure. After the tire pressure reaches the required value, the air pump is controlled to stop working through the command. When the tire pressure needs to be lowered, the ECU will send a command to the control box. After receiving the command from the ECU, the control box opens the corresponding valve to allow the gas in the tire to be discharged. The ECU continuously monitors the tire pressure until the required low tire pressure level is reached. Among them, the inflation structure of the wheel is as shown in the figure. Figure 3 shown.
[0082] According to the vehicle control method of the present application, when the cruising range assist function is turned on, the first vehicle speed and tire pressure value of the vehicle during driving are obtained; when the first vehicle speed is greater than or equal to the first preset value, if the tire pressure value is less than the first preset range or is within the first preset range, the second vehicle speed of the vehicle is obtained after the first preset time; when the second vehicle speed is greater than or equal to the first preset value, the tire pressure value is increased to the second preset range so that the tire pressure value of the vehicle matches the vehicle speed. The embodiment of the present application obtains the vehicle speed and tire pressure of the vehicle during driving. If the vehicle speed is high, the vehicle speed is obtained again after a period of time, and the tire pressure is actively increased when the vehicle speed is stable above the first preset value to reduce the rolling resistance of the wheel and improve the cruising range of the vehicle. In addition, since the increase in tire pressure is performed after the vehicle speed is stable, the energy waste and reduced comfort caused by frequent adjustment of tire pressure when the vehicle speed fluctuates around the first preset value are avoided, thereby improving the cruising range of the vehicle while reducing the reduction in comfort to a certain extent.
[0083] In some embodiments, the vehicle includes a tire pressure control start-stop button, and when the tire pressure control start-stop button is triggered, the endurance assist function is turned on.
[0084] In this embodiment, the tire pressure control start-stop button can be a physical button installed in the cockpit of the vehicle, such as near the steering wheel or on the center console, so that the user can quickly access and operate it. The tire pressure control start-stop button can also be a virtual button, for example, the button can be presented on the touch screen of the vehicle and interact with the user through a graphical user interface.
[0085] Whether it is a physical button or a virtual button, the action to trigger the tire pressure control start-stop button can be pressing the button. For a physical button, the user only needs to press the button, and the mechanical or electronic switch inside the button will be activated, sending a signal to the vehicle's control system to turn on the range assistance function. For a virtual button, the user can touch or long press the corresponding icon on the touch screen, and the system will recognize this operation and turn on the range assistance function.
[0086] In this embodiment, the start and stop of the range assist function is controlled by the tire pressure control start / stop button, so that the user can decide whether to turn on the range assist function according to needs, thereby achieving a balance between range and comfort by selecting appropriate tire pressure according to personal driving habits without affecting comfort.
[0087] In some embodiments, the method further comprises:
[0088] Obtain the user's driving style;
[0089] The first preset value is adjusted according to the driving style.
[0090] In this embodiment, driving style refers to a series of behavioral characteristics exhibited by the driver during driving, including but not limited to the use of acceleration, frequency and strength of braking, frequency and amplitude of steering, control of vehicle speed, and compliance with traffic regulations, etc. Different driving styles will affect the vehicle's fuel efficiency, tire wear, vehicle maintenance costs, and passenger comfort.
[0091] In this embodiment, the vehicle may be equipped with sensors that can monitor and record driving behavior. These sensors may include accelerometers, gyroscopes, GPS, wheel speed sensors, etc., which can capture the vehicle's motion data and driving behavior. The driving behavior pattern is then analyzed based on the received data. For example, based on machine learning, smooth driving, aggressive driving, or other driving styles can be identified. Based on the analysis results, the driving style can be classified into several preset types, such as "economical", "comfortable", "sporty", etc., each type corresponding to different driving habits and vehicle performance requirements.
[0092] Based on the classification of driving styles, the first preset value, i.e. the speed threshold for triggering tire pressure adjustment, can be automatically adjusted. For example, for users with an "economical" driving style, a lower first preset value can be set so that tire pressure can be optimized at a lower speed to improve fuel efficiency; while for users with a "sporty" driving style, the first preset value can be increased to adapt to more aggressive driving behavior and ensure vehicle controllability and stability.
[0093] In this embodiment, the first preset value is adjusted by analyzing the user's driving style, so as to achieve personalized settings based on the actual driving needs and preferences of different users. This not only improves the vehicle's endurance, but also provides a more intelligent and personalized driving experience without sacrificing comfort.
[0094] In some embodiments, when the second vehicle speed is greater than or equal to the first preset value, the tire pressure value is increased to a second preset range so that the tire pressure value of the vehicle matches the vehicle speed, including:
[0095] Determining a target vehicle speed gear position for the second vehicle speed; wherein different vehicle speed gear positions correspond to different vehicle speed ranges;
[0096] Based on the preset correlation between the vehicle speed gear and the tire pressure gear, the tire pressure value is increased to a target tire pressure gear corresponding to the target vehicle speed gear; wherein different tire pressure gears correspond to different tire pressure value ranges.
[0097] In this embodiment, the gears can be divided according to the size of the vehicle speed, and the gears can be divided according to the size of the tire pressure, wherein the gear corresponding to the lower vehicle speed matches the gear corresponding to the lower tire pressure, and the gear corresponding to the higher vehicle speed matches the gear corresponding to the higher tire pressure. For example, the vehicle speed can be divided into high-speed gears and medium-low-speed gears, and the tire pressure can be divided into economic tire pressure and standard tire pressure, wherein the high-speed gear matches the economic tire pressure, the medium-low-speed gear matches the standard tire pressure, and the value of the economic tire pressure is greater than the value of the standard tire pressure. More gears can also be divided according to the corresponding relationship between the vehicle speed and the tire pressure, for example, the vehicle speed can be divided into low-speed gears, medium-speed gears, and high-speed gears, and the tire pressure can be divided into low tire pressure, standard tire pressure, and high tire pressure, wherein the low-speed gear matches the low tire pressure, the medium-speed gear matches the standard tire pressure, and the high-speed gear matches the high tire pressure, and this application does not limit this.
[0098] In this embodiment, the target vehicle speed gear of the second vehicle speed can be determined, and then the target tire pressure gear corresponding to the target vehicle speed gear is found according to the correlation between the vehicle speed gear and the tire pressure gear, and the tire is inflated to increase the tire pressure value to the target tire pressure gear. It should be noted that the tire pressure value corresponding to the target tire pressure gear is within the second preset range.
[0099] In this embodiment, by setting the correlation between the vehicle speed gear and the tire pressure gear, the tire pressure can be intelligently adjusted according to the change of vehicle speed, thereby achieving fine control of vehicle performance, thereby further reducing energy loss, optimizing overall energy consumption performance, and extending the vehicle's driving distance.
[0100] In some embodiments, the vehicle includes a display screen, the display screen provides a custom interface for the range assistance function, and the method further includes:
[0101] Receive the association relationship between the vehicle speed gear and the tire pressure gear, and / or the first preset value, input by the user in the custom interface of the endurance assistance function.
[0102] In this embodiment, the display screen of the vehicle can be located on the dashboard or center console of the vehicle, or at other locations of the vehicle. The display screen can serve as an interface for user interaction, providing various settings and control options, allowing the user to operate by touch or physical buttons.
[0103] On the display screen of the vehicle, the cruise control assist function customization interface can be a dedicated menu or application through which the user can access and adjust the settings related to the cruise control. The cruise control assist function customization interface can include various options, such as the first preset value setting, the corresponding relationship between the tire pressure value and the vehicle speed, etc.
[0104] In the custom interface of the endurance assistance function, users can set the relationship between the speed gear and the tire pressure gear. Users can select or enter different speed intervals and specify an ideal tire pressure range for each interval. For example, users can browse different setting options, select the "Speed and Tire Pressure Association" setting, and enter or adjust the desired speed gear and the corresponding tire pressure gear. In some embodiments, users can set a higher tire pressure to reduce rolling resistance when driving at low speeds.
[0105] The user can also enter or adjust the first preset value in the custom interface, which is the speed threshold that triggers tire pressure adjustment. The first preset value can be set according to the user's own driving habits and vehicle usage to ensure that when a certain speed is reached, the system automatically adjusts the tire pressure to optimize the range.
[0106] In this embodiment, a display screen is integrated into the vehicle and a custom interface for the endurance assistance function is provided to allow the user to input the correlation between the vehicle speed gear and the tire pressure gear or a preset value according to personal preferences and driving needs. This allows the user to directly participate in the vehicle performance optimization process and customize the matching scheme of tire pressure and vehicle speed according to actual driving conditions and expected driving efficiency. This not only improves the vehicle's energy efficiency and extends the endurance, but also meets the user's personalized requirements for vehicle performance.
[0107] In some embodiments, when the first vehicle speed is less than the first preset value, if the tire pressure value is greater than the first preset range, a third vehicle speed of the vehicle is obtained after a second preset time;
[0108] When the third vehicle speed is less than the first preset value, the tire pressure value is reduced to the first preset range so that the tire pressure value of the vehicle matches the vehicle speed.
[0109] When the first vehicle speed is less than the first preset value, it means that the vehicle is currently driving at a low speed. In this case, the tire pressure needs to be reduced to a certain range to improve comfort. When the tire pressure is greater than the first preset range, it means that the tire pressure is too high and needs to be reduced.
[0110] However, due to factors such as the road environment on which the vehicle is traveling, the vehicle speed may change continuously. When the first vehicle speed is less than the first preset value, if the tire pressure is greater than the first preset range, if the tire pressure is adjusted immediately, the vehicle speed may be greater than or equal to the first preset value within a very short period of time, and the tire pressure must be increased again, resulting in too frequent adjustment of the tire pressure, wasting energy and reducing ride comfort.
[0111] In this embodiment, in order to reduce the situation where the tire pressure keeps changing when the vehicle speed fluctuates around the preset value, a second preset time can be set. When the first vehicle speed is less than the first preset value, if the tire pressure value is greater than the first preset range, the third vehicle speed is obtained after the second preset time, and whether the vehicle speed is stable is determined based on whether the third vehicle speed is still less than the first preset value, and the tire pressure value is adjusted when the vehicle speed is stable.
[0112] If the third vehicle speed after the second preset time is still less than the first preset value, it means that the vehicle speed has stabilized below the first preset value. In this case, the wheels can be deflated to reduce the tire pressure to the first preset range. The second preset time can be 2s, 3s, 5s, etc. Those skilled in the art can set different values according to actual conditions, and the embodiments of the present application do not limit this.
[0113] In this embodiment, the vehicle speed and tire pressure are obtained during driving. If the vehicle speed is low, the vehicle speed is obtained again after a period of time. When the vehicle speed stabilizes below a first preset value, the tire pressure is actively reduced to increase the contact area between the tire and the ground and improve vehicle comfort.
[0114] The vehicle control method provided in the embodiment of the present application can be executed by a vehicle control device. In the embodiment of the present application, the vehicle control device provided in the embodiment of the present application is described by taking the vehicle control method executed by the vehicle control device as an example.
[0115] An embodiment of the present application also provides a vehicle control device.
[0116] like Figure 4 As shown, the vehicle control device includes:
[0117] The first acquisition module 410 is used to acquire a first vehicle speed and tire pressure value of the vehicle during driving when the endurance assistance function is turned on;
[0118] The second acquisition module 420 is used to acquire a second vehicle speed of the vehicle after a first preset time if the tire pressure value is less than the first preset range or is within the first preset range when the first vehicle speed is greater than or equal to the first preset value;
[0119] The increasing module 430 is used to increase the tire pressure value to a second preset range when the second vehicle speed is greater than or equal to the first preset value, so that the tire pressure value of the vehicle matches the vehicle speed.
[0120] According to the vehicle control device of the present application, when the cruising range assist function is turned on, the first vehicle speed and tire pressure value of the vehicle during driving are obtained; when the first vehicle speed is greater than or equal to the first preset value, if the tire pressure value is less than the first preset range or is within the first preset range, the second vehicle speed of the vehicle is obtained after the first preset time; when the second vehicle speed is greater than or equal to the first preset value, the tire pressure value is increased to the second preset range so that the tire pressure value of the vehicle matches the vehicle speed. The embodiment of the present application obtains the vehicle speed and tire pressure of the vehicle during driving. If the vehicle speed is high, the vehicle speed is obtained again after a period of time, and the tire pressure is actively increased when the vehicle speed is stable above the first preset value to reduce the rolling resistance of the wheel and improve the cruising range of the vehicle. Moreover, since the increase in tire pressure is performed after the vehicle speed is stable, the energy waste and the problem of reduced comfort caused by frequent adjustment of tire pressure when the vehicle speed fluctuates around the first preset value are avoided, thereby improving the cruising range of the vehicle while reducing the reduction in comfort to a certain extent.
