Abstract
Description
Technical Field
[0001] The present application relates to the field of vehicle technology, and specifically to a vehicle control method, device, vehicle and storage medium. Background Art
[0002] A hybrid vehicle is a new energy vehicle that has both an engine and an electric motor. The working principle of a hybrid vehicle is to control the engine and the electric motor to work together through the vehicle controller. In practical applications, the energy modes of hybrid vehicles usually include hybrid mode (Hybrid Electrical Vehicle, HEV) and pure electric mode (Electrical Vehicle, EV).
[0003] The state of charge (SOC) value is the target for hybrid vehicles to maintain their charge. However, the current SOC value is usually a fixed value, which may cause the engine to be connected too early (i.e., switch to HEV mode too early) in some application scenarios, which may lead to high fuel consumption and high noise in hybrid vehicles. For example, on urban roads, users expect to drive hybrid vehicles in EV mode as much as possible. Since the SOC value is a fixed value, according to the energy mode switching strategy set by the hybrid vehicle, when the remaining charge of the hybrid vehicle is lower than the SOC value, switching to HEV mode may cause the engine to be connected too early, which may lead to high fuel consumption and high noise in hybrid vehicles. In other application scenarios, it may cause the engine to be connected too late (i.e., switch to HEV mode too late), which may lead to insufficient power in hybrid vehicles. For example, on highways, users expect to drive hybrid vehicles in HEV mode as much as possible. Since the SOC value is a fixed value, according to the energy mode switching strategy set by the hybrid vehicle, when the remaining charge of the hybrid vehicle is higher than the SOC value, switching to EV mode may cause the engine to be connected too late, which may lead to insufficient power in hybrid vehicles.
[0004] Therefore, if the hybrid vehicle's engine is connected too early or too late, it may cause the hybrid vehicle to have high fuel consumption, loud noise and insufficient power.
[0005] It should be pointed out that the information disclosed in the background technology section of this application is only intended to deepen the understanding of the general background technology of this application, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to those skilled in the art. Summary of the invention
[0006] In view of this, the present application provides a vehicle control method, device, vehicle and storage medium to help solve the problems of high fuel consumption, high noise and insufficient power of hybrid vehicles due to engine connection too early or too late.
[0007] In a first aspect, an embodiment of the present application provides a vehicle control method, wherein the vehicle is a hybrid vehicle, and the energy mode of the hybrid vehicle includes a hybrid mode and a pure electric mode, and the method includes: Acquiring driving road condition information of the vehicle, wherein the driving road condition information is used to characterize the road condition on which the vehicle is driving; According to the driving road condition information, the state of charge value of the vehicle is set as a target value, the state of charge value being used to represent a power retention target of the vehicle; Determining a target energy mode according to the remaining power of the vehicle and the target value, the target energy mode being a hybrid power mode or a pure electric mode; The vehicle is controlled to travel according to the target energy mode.
[0008] In the present application example, the vehicle can adjust the vehicle's state of charge value according to driving road condition information, which can indirectly control the timing of switching energy modes, thereby avoiding the engine being connected too early or too late, thereby reducing the vehicle's fuel consumption and noise to a certain extent and improving the vehicle's power.
[0009] In a possible implementation, the obtaining of the vehicle's driving road condition information includes: In the navigation map of the vehicle, the driving road condition information of the vehicle is obtained.
[0010] In an embodiment of the present application, the vehicle can collect a wider range of driving road condition information according to the navigation map, and then determine a more accurate state of charge value. In a possible implementation, the state of charge value of the vehicle is set to a target value according to the driving road condition information, including: Determining an expected driving distance of the vehicle according to the driving road condition information; If the expected driving distance is greater than or equal to a preset driving distance threshold, the state of charge value of the vehicle is set to a first target value, and the first target value is greater than a default value of the state of charge value of the vehicle.
[0011] In the embodiment of the present application, the vehicle can increase the state of charge value according to the driving distance, so that the remaining power of the vehicle can be maintained at a higher level. When the vehicle passes through urban roads or congested sections during driving, it can ensure that the vehicle has enough remaining power to switch to pure electric mode, which can avoid excessive reliance on the engine during the entire driving process, and reduce the fuel consumption and noise of the vehicle to a certain extent.
[0012] In a possible implementation, setting the state of charge value of the vehicle to a target value according to the driving road condition information includes: If it is determined according to the driving road condition information that the driving road of the vehicle is a highway, the state of charge value of the vehicle is set to a second target value, and the second target value is greater than a default value of the state of charge value of the vehicle.
[0013] In an embodiment of the present application, when it is determined based on driving road condition information that the vehicle is traveling on a highway, the second target value can be increased, so that the vehicle can be switched to hybrid mode as soon as possible, thereby avoiding the engine being connected too late, thereby improving the power of the vehicle to a certain extent.
[0014] In a possible implementation, if it is determined according to the driving road condition information that the driving road of the vehicle is a highway, setting the state of charge value of the vehicle to a second target value includes: If it is determined according to the driving road condition information that the driving road of the vehicle is a highway, and the remaining power of the vehicle is greater than or equal to a preset first remaining power threshold, then the state of charge value of the vehicle is set to a second target value; If it is determined according to the driving road condition information that the driving road of the vehicle is a highway, and the remaining power of the vehicle is less than or equal to a preset second remaining power threshold, the state of charge value of the vehicle is set to a third target value, and a forced power conservation mode is enabled so that the remaining power of the vehicle is maintained at the third target value, and the third target value is the current remaining power of the vehicle; The first remaining power threshold is greater than the second remaining power threshold.
[0015] In the implementation of this application, the state of charge value of the vehicle can be adjusted according to the remaining power of the vehicle. When the remaining power of the vehicle is greater than or equal to the remaining power threshold, the state of charge value of the vehicle can be increased so that the vehicle can use the hybrid power mode as much as possible, thereby avoiding the engine from being connected too late, and improving the power of the vehicle to a certain extent.
[0016] When the remaining power of the vehicle is less than the remaining power threshold, the state of charge value of the vehicle can be reduced, and the forced power conservation mode can be enabled, and the engine can be started to charge the battery, so that the remaining power of the vehicle can be kept at the target value. When the remaining power of the vehicle reaches the third target value, the engine can stop charging, which reduces the fuel consumption and noise of the vehicle to a certain extent.
[0017] In a possible implementation, setting the state of charge value of the vehicle to a target value according to the driving road condition information includes: If it is determined according to the driving road condition information that the driving road of the vehicle is an urban road, the state of charge value of the vehicle is set to a fourth target value, and the fourth target value is smaller than a default value of the state of charge value of the vehicle.
[0018] In an embodiment of the present application, when it is determined based on driving road condition information that the vehicle is traveling on an urban road, the state of charge value can be reduced so that the vehicle can adopt pure electric mode as much as possible, thereby avoiding the engine from being connected too early, thereby reducing the vehicle's fuel consumption and noise to a certain extent.
[0019] In a possible implementation, determining the target energy mode according to the remaining power of the vehicle and the target value includes: According to the remaining power of the vehicle and the target value, determining whether the remaining power of the vehicle is greater than or equal to the target value; If the remaining power of the vehicle is greater than or equal to the target value, determining the target energy mode to be a pure electric mode; If the remaining power of the vehicle is less than the target value, the target energy mode is determined to be a hybrid power mode.
[0020] In an embodiment of the present application, the target energy mode can be determined based on the remaining power of the vehicle and the target value, which can indirectly control the timing of switching the energy mode, thereby avoiding the engine being connected too early or too late, thereby reducing the vehicle's fuel consumption and noise to a certain extent and improving the vehicle's power.
[0021] In a second aspect, an embodiment of the present application provides a vehicle control device, wherein the vehicle is a hybrid vehicle, and the energy mode of the hybrid vehicle includes a hybrid mode and a pure electric mode, and the device includes: An information acquisition module, used to acquire the driving road condition information of the vehicle, wherein the driving road condition information is used to characterize the road condition of the vehicle; a state of charge value determination module, used to set the state of charge value of the vehicle as a target value according to the driving road condition information, the state of charge value being used to represent a power retention target of the vehicle; a target energy mode determination module, configured to determine a target energy mode according to the remaining power of the vehicle and the target value, wherein the target energy mode is a hybrid power mode or a pure electric mode; A vehicle control module is used to control the vehicle to travel according to the target energy mode.

[0031] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0032] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0034] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0035] Hybrid vehicles are an important application of new energy technologies in the field of transportation. Figure 1 , is a schematic diagram of an application scenario provided by an embodiment of the present application. Figure 1 As shown, the vehicle 100 is a hybrid vehicle, including a processing unit 101 and a vehicle controller 102. The processing unit 101 and the vehicle controller 102 are connected in communication. The processing unit 101 can be used to pre-process the received data; the vehicle controller 102 can be used to switch the energy mode according to the pre-processed data in the processing unit 101.
[0036] In practical applications, the energy modes of hybrid vehicles usually include hybrid mode (HEV) and pure electric mode (EV). In HEV mode, the electric motor and the engine are used as the power source to drive the vehicle; in EV mode, the electric motor is used as the power source to drive the vehicle. Therefore, hybrid vehicles can control the timing of engine connection according to the switching of energy modes, thereby improving fuel efficiency to a certain extent.
[0037] The State Of Charge (SOC) value is the target for the hybrid vehicle to maintain its charge. The vehicle controller of the hybrid vehicle can switch the energy mode according to the SOC value. Specifically, when the remaining charge of the hybrid vehicle is lower than the SOC value, the hybrid vehicle switches to the HEV mode. When the remaining charge of the hybrid vehicle is higher than the SOC value, the hybrid vehicle switches to the EV mode.
[0038] However, the current SOC value is usually a fixed value, which may cause the engine to be connected too early (i.e., switch to HEV mode too early) in some application scenarios, which may lead to high fuel consumption and high noise of hybrid vehicles. For example, on urban roads, users expect to use EV mode to drive hybrid vehicles as much as possible. Since the SOC value is a fixed value, according to the energy mode switching strategy set by the hybrid vehicle, when the remaining power of the hybrid vehicle is lower than the SOC value, switching to HEV mode may cause the engine to be connected too early, which may lead to high fuel consumption and high noise of the hybrid vehicle. In other application scenarios, it may cause the engine to be connected too late (i.e., switch to HEV mode too late), which may lead to insufficient power of the hybrid vehicle. For example, on highways, users expect to use HEV mode to drive hybrid vehicles as much as possible. Since the SOC value is a fixed value, according to the energy mode switching strategy set by the hybrid vehicle, when the remaining power of the hybrid vehicle is higher than the SOC value, switching to EV mode may cause the engine to be connected too late, which may lead to insufficient power of the hybrid vehicle.
[0039] Therefore, if the hybrid vehicle's engine is connected too early or too late, it may cause the hybrid vehicle to have high fuel consumption, loud noise and insufficient power.
[0040] In view of the above problems, in an embodiment of the present application, the vehicle's driving road condition information is first obtained; secondly, the vehicle's state of charge value is set to a target value according to the driving road condition information; then, the target energy mode is determined according to the vehicle's remaining power and the target value; finally, the vehicle is controlled to travel according to the target energy mode. Among them, the driving road condition information is used to characterize the road conditions on which the vehicle is traveling. Since the energy modes that match different road conditions are usually different, and the state of charge value can affect the switching timing of the energy mode, therefore, adjusting the state of charge value according to the road conditions can indirectly control the switching timing of the energy mode, thereby avoiding the engine being connected too early or too late, reducing the vehicle's fuel consumption and noise to a certain extent, and improving the vehicle's power.
[0041] Specifically, a detailed description is given below in conjunction with the accompanying drawings and specific embodiments.
[0042] See also Figure 2 , is a flow chart of a vehicle control method provided in an embodiment of the present application. The method can be applied to Figure 1 In the application scenario shown, Figure 2 As shown, it mainly includes the following steps.
[0043] S201: Acquire the vehicle's driving road condition information.
[0044] In the embodiment of the present application, the driving road condition information is used to characterize the road condition of the vehicle. The driving road condition information may include the population density, road congestion, housing density, etc. in the vehicle's driving route. Of course, the driving road condition information may also include other aspects, which are not specifically limited in the present application.
[0045] In actual applications, the driving road condition information can be collected by the camera in the vehicle. However, since the camera is easily blocked by obstructions (pedestrians, vehicles) or affected by light when collecting driving road condition information, the driving road condition information obtained may be inaccurate, which may lead to deviations in the adjustment of the state of charge value. In addition, the driving road condition information collected by the camera usually covers a small range and may not be able to collect driving road condition information in a wider range, which may lead to large errors in determining the state of charge value based on the driving road condition information.
[0046] In a possible implementation, the vehicle's driving road condition information may be obtained from a navigation map of the vehicle.
[0047] Specifically, the navigation map of the vehicle can be set in the above processing unit, see Figure 3 , is a schematic diagram of the structure of a processing unit provided in an embodiment of the present application. Figure 3 As shown, the processing unit 101 includes: a map navigation module 1011 and a SOC value and energy mode setting module 1012. The map navigation module 1011 and the SOC value and energy mode setting module 1012 are connected in communication. The map navigation module 1011 can be configured with a navigation map for obtaining the driving road condition information of the vehicle; the SOC value and energy mode setting module 1012 is used to set the SOC value and the target energy mode according to the received driving road condition information.
[0048] In the embodiment of the present application, since the sensor of the navigation map can receive signals at different distances, the vehicle can collect a wider range of driving road condition information based on the navigation map, and thus can determine more accurate road conditions and thus determine a more accurate state of charge value.
[0049] S202: Setting the state of charge of the vehicle to a target value according to the driving road condition information.
[0050] In practical applications, since the energy modes that match different driving road condition information are usually different and the state of charge value can affect the switching timing of the energy mode, the state of charge value can be adjusted according to the road conditions.
[0051] In one possible implementation, the expected driving distance of the vehicle can be determined based on driving road condition information; if the expected driving distance is greater than or equal to a preset driving distance threshold, the vehicle's state of charge value is set to a first target value, and the first target value is greater than a default value of the vehicle's state of charge value.
[0052] The expected driving distance can be considered as the distance from the departure point to the destination in the current driving route of the vehicle. For example, if the distance from the departure point to the destination is 100 kilometers, the expected driving distance is 100 kilometers; similarly, if the distance from the departure point to the destination is 60 kilometers, the expected driving distance is 60 kilometers; and so on, which will not be described in detail in the embodiments of the present application.
[0053] The default value of the state of charge value of the vehicle can be considered as the initial value of the state of charge, which can be 40%, 50%, 60%, 70%, etc. This application does not set a specific limit for this.
[0054] The first target value is greater than a default value of the state of charge of the vehicle. For example, the default value of the state of charge of the vehicle is 30%, and the first target value may be 40%, 45%, 50%, 55%, 60%, etc.
[0055] In the embodiment of the present application, the SCO value and energy setting module described above can receive the driving road condition information of the vehicle's current driving route. After receiving the driving road condition information, the SCO value and energy setting module can obtain the expected driving distance of the vehicle by analyzing the driving road condition information.
[0056] As described above, after determining the expected driving distance of the vehicle, it is also necessary to determine whether to set the state of charge value of the vehicle to the first target value according to the expected driving distance of the vehicle. Specifically, a driving distance threshold value can be preset, and then the first target threshold value is determined according to the expected driving distance of the vehicle and the preset driving distance threshold value.
[0057] It should be noted that the preset driving distance threshold is a value pre-set by those skilled in the art, which may be 50 kilometers, 60 kilometers, 70 kilometers, 80 kilometers, etc. Of course, the user may also adjust the preset driving distance threshold according to actual needs, and this application does not set a specific limit for this.
[0058] In the embodiment of the present application, when the expected driving distance is greater than or equal to the preset driving distance threshold, the first target value can be increased, so that the remaining power of the vehicle can be maintained at a higher level. When the vehicle passes through urban roads or congested sections during driving, it can be ensured that the vehicle has enough power to switch to pure electric mode, which can avoid excessive reliance on the engine during the entire driving process, and reduce the fuel consumption and noise of the vehicle to a certain extent.
[0059] In some application scenarios, users expect to use hybrid mode as much as possible. Since the vehicle's state of charge is a fixed value, according to the energy mode switching strategy set for the vehicle, when the remaining power of the hybrid vehicle is higher than the vehicle's state of charge, switching to pure electric mode may cause the engine to be connected too late, which may cause the hybrid vehicle to be underpowered.
[0060] Therefore, in one possible implementation, if it is determined based on the driving road condition information that the vehicle is driving on a highway, the vehicle's state of charge value is set to a second target value, and the second target value is greater than the default value of the vehicle's state of charge value.
[0061] The second target value is greater than a default value of the state of charge of the vehicle. For example, if the default value of the state of charge of the vehicle is 40%, the second target value may be 45%, 50%, 55%, 60%, etc.
[0062] In practical applications, as described above, the SCO value and energy setting module can receive the driving road condition information of the vehicle's current driving route. After receiving the driving road condition information, the SCO value and energy setting module can determine whether the vehicle's driving road is a highway by analyzing the driving road condition information. When it is determined that the vehicle's driving road is a highway, the vehicle's state of charge value is set to the second target value.
[0063] In the embodiment of the present application, it can be determined whether the current road the vehicle is traveling on is a highway based on the driving road condition information. If the current road the vehicle is traveling on is a highway, the second target value can be increased. When the remaining power is lower than the second target value, the vehicle can be switched to a hybrid power mode, which can connect the engine as soon as possible, thereby improving the power of the vehicle to a certain extent.
[0064] In one possible implementation, if it is determined based on the driving road condition information that the vehicle is traveling on a highway and the remaining power of the vehicle is greater than or equal to a preset first remaining power threshold, the vehicle's state of charge value is set to a second target value.
[0065] If it is determined according to the driving road condition information that the vehicle is traveling on a highway and the remaining power of the vehicle is less than or equal to a preset second remaining power threshold, the state of charge value of the vehicle is set to a third target value, and the forced power conservation mode is enabled so that the remaining power of the vehicle is maintained at the third target value, and the third target value is the current remaining power of the vehicle; The first remaining power threshold is greater than the second remaining power threshold.
[0066] Among them, the forced power conservation mode can control the engine to charge the vehicle's battery so that the remaining power of the vehicle is maintained at a third target value.
[0067] The third target value is the current remaining power of the vehicle. For example, if the current remaining power of the vehicle is 30%, the third target value is 30%; similarly, if the current remaining power of the vehicle is 35%, the third target value is 35%; and so on, which will not be described in detail in the present embodiment of the application.
[0068] It should be noted that the first remaining power threshold and the second remaining power threshold are values pre-set by those skilled in the art. The first remaining power threshold may be 60%, 70%, 80%, etc.; the second remaining power threshold may be 30%, 40%, 50%, etc.
[0069] Of course, according to actual needs, the user can also adjust the first remaining power threshold and the second remaining power threshold, and this application does not set specific limits for this.
[0070] In practical applications, as described above, after determining that the vehicle is traveling on a highway, the state of charge value of the vehicle can also be adjusted according to the remaining power of the vehicle. Specifically, a remaining power threshold (a first remaining power threshold or a second remaining power threshold) can be preset, and then the state of charge value of the vehicle can be adjusted to the second target value or the third target value according to the remaining power of the vehicle and the preset remaining power threshold.
[0071] In the embodiment of the present application, when the vehicle is traveling on a highway, if the remaining power of the vehicle is less than or equal to the preset second remaining power threshold, the third target value can be adjusted to the current remaining power of the vehicle, and the forced power conservation mode is enabled, so that the engine can charge the battery of the vehicle to keep the remaining power of the vehicle at the third target value. When the remaining power of the vehicle reaches the third target value, the engine can stop charging, which reduces the fuel consumption and noise of the vehicle to a certain extent.
[0072] In other application scenarios, users expect to use pure electric mode as much as possible. Since the state of charge of the vehicle is a fixed value, according to the energy mode switching strategy set by the vehicle, when the remaining power of the hybrid vehicle is lower than the state of charge of the vehicle, switching to hybrid mode may cause the engine to be connected too early, which may lead to high fuel consumption and high noise.
[0073] Therefore, in one possible implementation, if it is determined based on the driving road condition information that the vehicle is driving on an urban road, the vehicle's state of charge value is set to a fourth target value, and the fourth target value is less than the default value of the vehicle's state of charge value.
[0074] The fourth target value is less than a default value of the state of charge of the vehicle. For example, if the default value of the state of charge of the vehicle is 60%, the fourth target value may be 55%, 50%, 45%, 40%, etc.
[0075] In practical applications, as described above, the SCO value and energy setting module can receive the driving road condition information of the vehicle's current driving route. After receiving the driving road condition information, the SCO value and energy setting module can determine whether the vehicle's driving road is an urban road by analyzing the driving road condition information. When it is determined that the vehicle's driving road is an urban road, the vehicle's state of charge value is set to the fourth target value.
[0076] In the embodiment of the present application, it can be determined whether the current driving road of the vehicle is an urban road according to the driving road condition information. If the current driving road of the vehicle is an urban road, the fourth target value can be reduced. When the remaining power is higher than the fourth target value, the vehicle can be switched to the pure electric mode, which reduces the fuel consumption and noise of the vehicle to a certain extent.
[0077] S203: Determine a target energy mode according to the remaining power of the vehicle and the target value.
[0078] Specifically, in a possible implementation, according to the remaining power of the vehicle and the target value, it is determined whether the remaining power of the vehicle is greater than or equal to the target value; If the remaining power of the vehicle is greater than or equal to the target value, the target energy mode is determined to be the pure electric mode; If the remaining power of the vehicle is less than the target value, the target energy mode is determined to be the hybrid power mode.
[0079] In actual applications, after the SCO value and energy setting module first sets the vehicle's state of charge value to the target value based on the received driving road condition information, it is also necessary to detect the vehicle's remaining power; then, based on the vehicle's remaining power and the target value, determine the target energy mode that matches the driving road condition information. At this time, the target energy mode is output to the vehicle controller to control the vehicle's driving.
[0080] In an embodiment of the present application, the target energy mode can be determined based on the remaining power of the vehicle and the target value, which can indirectly control the timing of switching the energy mode, thereby avoiding the engine being connected too early or too late, thereby reducing the vehicle's fuel consumption and noise to a certain extent and improving the vehicle's power.
[0081] S204: Controlling vehicle driving according to the target energy mode.
[0082] In practical applications, the vehicle controller mentioned above can receive the target energy mode output by the processor through the local area network interface, and can control the vehicle to travel according to the target energy mode through relevant instructions.
[0083] In the embodiment of the present application, the vehicle's driving road condition information is first obtained; secondly, the vehicle's state of charge value is set to a target value according to the driving road condition information; then, the target energy mode is determined according to the vehicle's remaining power and the target value; and finally, the vehicle is controlled to travel according to the target energy mode. It can be understood that by adjusting the state of charge according to the driving road condition information, the target energy mode corresponding to the driving road condition information can be determined, and the switching timing of the energy mode can be indirectly controlled, thereby avoiding the engine from being connected too early or too late, reducing the vehicle's fuel consumption and noise to a certain extent, and improving the vehicle's power.
[0084] See also Figure 4 , is a flow chart of another vehicle control method provided in an embodiment of the present application. The method can be applied to Figure 1 In the application scenario shown, Figure 4 It mainly includes the following steps.
[0085] Step S401: Start.
[0086] Step S402: Acquire the vehicle's driving road condition information.
[0087] Step S403: Determine the expected driving distance of the vehicle according to the driving road condition information.
[0088] Step S404: Determine whether the expected driving distance is greater than or equal to a preset driving distance threshold; if the expected driving distance is greater than or equal to the preset driving distance threshold, execute step S405; otherwise, execute step S406.
