Description
Technical Field
[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle control method, device, vehicle and storage medium. Background Art
[0002] A hybrid vehicle is a new energy vehicle that uses an electric motor and an engine as power sources. The energy modes of a hybrid vehicle generally include pure electric mode and hybrid mode. In pure electric mode, the electric motor is used as the power source to drive the vehicle; in hybrid mode, the electric motor and the engine are used as the power sources to drive the vehicle. Since different energy modes have different characteristics, in different application scenarios, the appropriate energy mode should be selected for the vehicle to improve the overall performance of the vehicle.
[0003] In the related art, the energy mode is usually switched manually by the user. However, this switching method is cumbersome to operate and overly dependent on the user's experience. If the user is inexperienced, the energy mode used by the vehicle may not match the application scenario, which may lead to insufficient power or low energy efficiency of the vehicle. For example, on a highway, if the vehicle uses a pure electric mode, it may cause the vehicle to be underpowered, affecting the user's driving experience; on a congested road, if the vehicle uses a hybrid mode, the frequent braking of the vehicle may lead to low energy efficiency, thereby shortening the vehicle's cruising range.
[0004] 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.

[0013] In an embodiment of the present application, when the vehicle faces complex road conditions, the matching logic of the target energy mode is simplified, making it easier and more direct for the vehicle to match the target energy mode on sections with complex road conditions.
[0014] In a possible implementation, if the road condition of any of the road sections is a highway, determining the target energy mode of any of the road sections to be a hybrid power mode includes: If the road condition of any of the road sections is a highway, and the road condition of any of the road sections is a congested road, then the target energy mode of any of the road sections is determined to be a pure electric 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.
[0033] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.
[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] To facilitate understanding, the concepts involved in the embodiments of the present application are first briefly described below.
[0036] Pure electric mode means that the vehicle completely relies on the electric motor as the power source for driving the vehicle, and the electric motor relies on battery power for driving. When the battery power is sufficient, the pure electric mode can significantly reduce fuel consumption, but due to objective factors such as battery aging or motor demagnetization, the vehicle's driving power is insufficient in pure electric mode, and it is difficult to meet the needs of stable high-speed driving. Therefore, it is suitable for use in low-speed or frequent braking scenarios, such as urban roads.
[0037] The hybrid mode combines two power sources, the engine and the electric motor, and is usually used in hybrid vehicles. In the hybrid mode, the vehicle can switch between the engine and the electric motor, or use both to provide power according to driving needs. This mode combines the advantages of the engine and the electric motor, which can reduce fuel consumption to a certain extent and provide sufficient power output. It is suitable for vehicles that need to drive steadily at high speeds, such as on highways.
[0038] Road conditions refer to a series of road condition information on the target driving route of the vehicle, which can be classified from multiple dimensions such as vehicle driving conditions, slope road conditions, and traffic congestion conditions. According to vehicle driving conditions, a series of road condition information is classified into: urban roads and expressways; according to slope road conditions, a series of road condition information is classified into: uphill roads and downhill roads; according to traffic congestion conditions, a series of road condition information is classified into: congested roads and smooth roads.
[0039] The remaining power threshold refers to the reference critical value of the remaining power of the vehicle that is allowed to switch to the pure electric mode. When the remaining power of the vehicle is lower than the remaining power threshold, the vehicle is controlled not to be allowed to switch to the pure electric mode.
[0040] The choice of two energy modes for hybrid vehicles is closely related to road conditions. Matching the appropriate energy mode according to road conditions can meet the driving needs of users in different scenarios. The pure electric mode is more suitable for use on urban roads and congested roads because it does not consume fuel but lacks power. It can greatly reduce fuel consumption and is more economical. In hybrid mode, the vehicle can use the engine to provide stable and powerful power output, which is more suitable for use on highways. On the contrary, if the hybrid mode is selected on urban roads or congested roads, it will cause fuel waste; if the pure electric mode is selected on highways, there will be a lack of power.
[0041] To facilitate understanding, a specific application scenario is first exemplified below.
[0042] See also Figure 1 , which provides a schematic diagram of an application scenario for the embodiment of the present application. Figure 1 As shown, the vehicle 101 includes: a controller 102, an engine 103 and a motor 104. Specifically, the vehicle 101 can control the working states of the engine 103 and the motor 104 through the controller 102.
[0043] The vehicle 101 is a hybrid vehicle having two power sources, an electric motor and an engine, and can be controlled by a controller to select one of them as a power source, or both as power sources at the same time, and can switch to use different energy modes. The vehicle 101 can be a light hybrid vehicle, a medium hybrid vehicle, a high-performance hybrid vehicle, a plug-in hybrid vehicle, etc.
[0044] The controller 102 can control the on or off, torque, speed and other working states of the engine 103 and the motor 104. The control method can be parallel mode, series mode, driving only by low-speed motor, etc.
[0045] The engine 104 can receive a control signal from the controller 102 to start or stop, and output corresponding torque, speed, etc. The engine 104 can be a diesel engine, a gasoline engine, a hybrid engine, etc.
[0046] The motor 104 can receive the control signal of the controller 102 to turn on or off, and output corresponding torque, speed, etc. The motor 104 can be a permanent magnet synchronous motor, an AC asynchronous motor, a DC motor, a switched reluctance motor, etc.
[0047] in addition, Figure 1 The vehicle structure shown in the figure is merely an exemplary description and should not be regarded as limiting the scope of protection of the present application.
[0048] In the related art, hybrid vehicles usually switch energy modes manually by users. However, this switching method is cumbersome to operate and overly dependent on the user's experience. If the user is inexperienced and the manually switched energy mode does not match the road conditions, it may cause the vehicle to be underpowered or have low energy efficiency. For example, on a highway, if the vehicle uses pure electric mode, it may cause the vehicle to be underpowered, affecting the user's driving experience; on a congested road, if the vehicle uses hybrid mode, due to frequent braking of the vehicle, it may lead to low energy efficiency, thereby shortening the vehicle's cruising range.
[0049] In view of the above problems, in the embodiment of the present application, firstly, the target driving route is divided into multiple sections according to the road conditions of the target driving route, and the road conditions of any two adjacent sections in the multiple sections are different; secondly, the target energy mode of each section is determined according to the road conditions of each section; and then, according to the target energy mode of each section, the vehicle is controlled to travel on each section. Since a preset value, i.e., the target energy mode, is set for the energy mode to be switched of the vehicle in each section of the target driving route, the vehicle can be controlled to automatically switch the energy mode between each section according to the target energy mode, thus avoiding manual switching by the user, thereby avoiding the problem of mismatch between the energy mode of the vehicle and the road conditions, and further avoiding the problem of insufficient power or low energy efficiency of the vehicle to a certain extent.
[0050] Specifically, a detailed description is given below in conjunction with the accompanying drawings and specific embodiments.
[0051] 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.
[0052] Step S201: Divide the target driving route into multiple sections according to the road conditions of the target driving route.
[0053] In practical applications, the target driving route is first obtained through the navigation system according to the coordinates of the departure place and the destination, and then the road conditions on the target driving route are obtained. Then, according to the road conditions on the target driving route, the target driving route is divided into multiple sections, and the road conditions of any two adjacent sections in the multiple sections are different.
[0054] As mentioned above, road conditions can be classified by multiple dimensions. Similarly, the target driving route can be divided into sections according to the road conditions of different dimensions. Then, the sections divided by different dimensions may contain each other. For example, there may be uphill roads and congested roads in urban roads.
[0055] Specifically, a detailed description is given below in conjunction with the accompanying drawings and specific embodiments.
[0056] For example, Figure 3 is a schematic diagram of the target driving route segment division. Figure 3 On the target driving route shown, the route is divided into four sections according to the driving conditions of the vehicle, namely, Section 1, Section 2, Section 3, and Section 4. Among them, the driving condition of the vehicle corresponding to Section 1 is the urban road, the driving condition of the vehicle corresponding to Section 2 is the expressway, the driving condition of the vehicle corresponding to Section 3 is the urban road, and the driving condition of the vehicle corresponding to Section 4 is the expressway. Slope road conditions and traffic congestion conditions may exist in Sections 1 to 4. For example, Section 5 may exist in Section 1, and the slope road condition of Section 5 is a downhill road. Section 6 may exist in Section 2, and the slope road condition of Section 6 is an uphill road. Similarly, there may be a smooth section in Section 3, and there may be a congested section in Section 4.
[0057] It should be pointed out that Figure 3 The target driving route segmentation schematic diagram shown is only an exemplary description of the target driving route segmentation according to road conditions. In actual applications, those skilled in the art can divide the target driving route into segments according to the actual road conditions of specific roads.
[0058] Step 202: Determine a target energy mode for each road section according to the road conditions of each road section.
[0059] In an embodiment of the present application, after the target driving route is segmented, an energy mode suitable for the current road conditions, namely, the target energy mode, is matched for each section according to the road conditions of each section.
[0060] Exemplarily, the corresponding relationship between the target energy mode and the vehicle driving condition is shown in Table 1: Table 1: It should be pointed out that Table 1 is only an exemplary description of the correspondence between road conditions and target energy modes. In actual applications, technicians in this field can set other correspondences between vehicle driving conditions and target energy modes according to specific target driving routes, such as the correspondence between suburban roads and target energy modes.
[0061] As can be understood from Table 1, after the target driving route is divided into sections according to the vehicle driving conditions, the method for determining the target energy mode of each section is as follows: if the vehicle driving condition of any section is an urban road, the target energy mode of the section is determined to be a pure electric mode; if the vehicle driving condition of any section is a highway, the target energy mode of the section is determined to be a hybrid power mode. Among them, the vehicle driving condition of the target driving route can generally be inferred from the information obtained by the navigation system.
[0062] For example, Figure 4 This is a schematic diagram of the corresponding relationship between the vehicle driving conditions and the road sections of the target energy mode. Figure 4 On the target driving route shown, the vehicle driving condition corresponding to section 1 is an urban road, so the target energy mode corresponding to section 1 is a pure electric mode, and the vehicle driving condition corresponding to section 2 is a highway, so the target energy mode corresponding to section 2 is a hybrid mode. Similarly, the method for determining the target energy mode of sections 3 and 4 is the same as that of sections 1 and 2, and will not be repeated here.
[0063] It should be pointed out that Figure 4 The schematic diagram of the correspondence between the vehicle driving condition and the target energy mode is only an exemplary illustration of the correspondence between the vehicle driving condition and the target energy mode. In actual applications, technicians in this field can determine the target energy mode for each road section based on the actual road conditions of the specific road.
[0064] Exemplarily, the corresponding relationship between the target energy mode and the slope road condition is shown in Table 2: Table 2: It can be understood from Table 2 that after the target driving route is divided into sections according to the slope road condition, the method of determining the target energy mode of each section is: if the slope road condition of any section is an uphill road, then the target energy mode of the section is determined to be the pure electric mode.
[0065] It should be pointed out that if the road condition of any section is a downhill road, the excess energy released by the vehicle during inertial gliding will be recovered, and the vehicle will be controlled to store the recovered energy in the vehicle's battery, thereby improving the energy utilization rate of the entire vehicle to a certain extent.
[0066] In practical applications, uphill roads and downhill roads can generally be determined by the altitude difference information obtained by the navigation system and a preset altitude difference threshold.
[0067] For example, the corresponding relationship between the target energy mode and the traffic congestion condition is shown in Table 3: Table 3: It can be understood from Table 3 that according to the traffic congestion condition, after the target driving route is divided into sections, the method of determining the target energy mode of each section is: if the traffic congestion condition of any section is a congested road, then the target energy mode of the section is determined to be the pure electric mode. Among them, the judgment standard of traffic congestion is that the traffic congestion index is greater than or equal to the preset traffic congestion index threshold, and the traffic congestion index can generally be obtained through the navigation system.
[0068] In actual application, if a congested road is encountered, the timing starts from the time the vehicle enters the congested road. If the timing duration exceeds the preset congestion duration value, the output is "Please re-plan the route".
[0069] It should be pointed out that if the traffic congestion condition of any road section changes to a smooth road, it is also necessary to determine the target energy mode of the road section based on the road condition information in other dimensions.
[0070] For example, Figure 5 This is a schematic diagram of the target energy mode for clear road confirmation. Figure 5 On the target driving route shown, the traffic congestion condition corresponding to section 1 is a smooth road. According to the road condition information of other dimensions, section 1 needs to be further divided into section 2, section 3 and section 4. Among them, section 2 is an urban road, so the target energy mode corresponding to section 2 is the pure electric mode; section 3 is a highway, so the target energy mode corresponding to section 3 is the hybrid power mode; section 4 is an uphill road, so the target energy mode corresponding to section 4 is the pure electric mode.
[0071] It should be pointed out that Figure 5 The schematic diagram of confirming the target energy mode for a clear road shown is only an exemplary illustration of confirming the target energy mode for a clear road. In actual applications, those skilled in the art can determine the target energy mode for each road section based on the actual road conditions of the specific road.
[0072] As mentioned above, road conditions have multiple division dimensions. Therefore, multiple road sections divided by different dimensions may contain each other, such as Figure 3 The schematic diagram of the target driving route segment division is shown.
[0073] Then, if the vehicle driving condition on any road section is a highway and there is an uphill road on the road section, the target energy mode of the vehicle on the uphill road section is determined to be the pure electric mode. If the vehicle driving condition on any road section is a highway and there is a congested road on the road section, the target energy mode of the vehicle on the congested road section is determined to be the pure electric mode.
[0074] For example, Figure 6 This is a schematic diagram of the target energy model for highway confirmation. Figure 6 In the example, section 1 is a highway, but it cannot be directly determined that the target energy mode of section 1 is the hybrid mode. Section 1 needs to be further divided according to the road conditions. Figure 6 As shown, there are also sections 2 and 3 in section 1, where section 2 is an uphill road and section 3 is a congested road. Therefore, the target energy mode of section 2 is confirmed to be pure electric mode, and the target energy mode of section 3 is confirmed to be pure electric mode. After removing sections 2 and 3 from section 1, the target energy mode of the remaining section 4 can be confirmed to be hybrid power mode.
[0075] It should be pointed out that Figure 6 The schematic diagram of determining the target energy mode on a highway is only an exemplary description for illustrating the method of determining the target energy mode on a highway section. In actual application, those skilled in the art can determine the target energy mode for each specific section according to the actual road conditions of the target driving route.
[0076] The remaining power of the vehicle is also an important factor in controlling the vehicle's energy mode switching. When the remaining power of the vehicle is less than the preset remaining power threshold, the vehicle cannot be switched to the pure electric mode. Therefore, the remaining power threshold of the vehicle can be adjusted to control whether the vehicle can use the pure electric mode.
[0077] In the embodiment of the present application, along the driving direction of the vehicle, the remaining power threshold of the vehicle is controlled to be lower in the latter section than in the former section. On the entire target driving route, the remaining power threshold of the vehicle is dynamically reduced in sections, and the number of sections in the second half of the target driving route where switching to pure electric mode is allowed will increase, which, to a certain extent, alleviates the problem of fuel waste.
[0078] For example, Figure 7 This is a schematic diagram of the remaining power threshold change. Figure 7In the , the target driving route is divided into four sections according to the road conditions, and the remaining power threshold of each section is controlled to gradually decrease along the vehicle's driving direction. Figure 7 As shown, along the driving direction of the vehicle, sections 1 to 4 are arranged in sequence, and the vehicle's remaining power threshold is set to 25 in section 1, 20 in section 2, 15 in section 3, and 10 in section 4. The remaining power threshold decreases successively, that is, the threshold for the vehicle to switch to and use the pure electric mode is lowered, thereby increasing the number of sections that can switch to and use the pure electric mode in the second half of the journey.
[0079] In actual applications, if the remaining power of the vehicle is lower than the default remaining power threshold, the output is "The current vehicle remaining power is insufficient, please charge in time". If there is a charging station near the vehicle, the output is "XX charging station is XXkm away from the current location, it is recommended to go to XX charging station to recharge". Among them, "nearby" means that there is a location coordinate, and the distance between the location coordinate and the vehicle location coordinate is less than the preset distance threshold.
[0080] Step S203: Controlling the vehicle to travel on each road section according to the target energy mode of each road section.
[0081] Through the method described in step S201 and step S202, a target driving route can be obtained, and the target driving route has been divided into multiple sections according to the road conditions, and the target energy mode of each section has been determined. Then, on each section, the vehicle can be controlled to automatically switch the energy mode and drive according to the determined target energy mode.
[0082] It should be pointed out that some factors that affect the switching of energy modes are constantly changing, and the information corresponding to these factors needs to be continuously obtained at preset time intervals in order to adjust the target energy mode in a timely manner so that the target energy mode can match the changed influencing factors. For example, the remaining power of the vehicle and the traffic congestion conditions are both dynamically changing. It is necessary to continuously obtain the remaining power of the vehicle and the traffic congestion conditions at preset time intervals during the dynamic driving of the vehicle, and adjust the target energy mode in a timely manner to match the changed remaining power and road conditions.
