Description

TECHNICAL FIELD

In new energy vehicles, an electric drive device is usually included, which has the characteristics of fast dynamic response, and therefore is suitable for intelligent auxiliary driving and unmanned driving applications such as adaptive cruise control, driving correction and agile navigation, and is welcomed by the majority of users.

[0003] In related technologies, some new energy vehicles have a regenerative charging function. Regenerative charging, also known as brake energy feedback, means that the new energy vehicle uses the reverse torque generated during the electric motor braking process to brake, and at the same time, the reverse electromotive force generated by the motor charges the vehicle-mounted power battery. This combined process is regenerative charging. For example, in some scenarios, the user lightly presses the brake and descends along a moderately sloping mountain road. In this process, the new energy vehicle can be charged, improving the utilization rate of energy. However, in actual applications, it is found that because the user may have less knowledge of the uphill and downhill conditions of the road and route, it is difficult to effectively utilize the regenerative charging function. For example, there may be a good road section ahead that can achieve regenerative charging, but the vehicle's power has been depleted and cannot travel to the road section, resulting in a low utilization rate of the regenerative charging function and a poor driving experience for the user.

[0046] The present application will be further described below with reference to the drawings and specific embodiments. The described embodiments should not be regarded as limiting the present application, and all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0047] In the following description, "some embodiments" are referred to, which describe a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0049] Before introducing the method provided by the embodiments of the present application, first, some background technologies involved in the present application are briefly described.

[0050] At present, with the increasing demand for environmental protection, the development of new energy vehicle (pure electric vehicle and hybrid vehicle) related technology is also changing rapidly. In new energy vehicles, electric drive devices are usually included, which have the characteristics of fast dynamic response, and therefore are suitable for intelligent auxiliary driving and unmanned driving applications such as adaptive cruise control, driving correction and agile navigation, and are welcomed by the majority of users.

[0051] In related technologies, some new energy vehicles have the function of regenerative charging, which is also called brake energy feedback. That is, the new energy vehicle brakes using the reverse torque generated during the electric motor braking process, and the reverse electromotive force generated by the motor charges the vehicle-mounted power battery. This composite process is regenerative charging. For example, in some scenarios, the user lightly presses the brake and drives down the winding road with moderate slope. In this process, the new energy vehicle can be charged to improve the utilization rate of energy. However, in actual application, it is found that because the user may have less knowledge about the uphill and downhill conditions of the road and route, it is difficult to effectively utilize the regenerative charging function. For example, there may be a good road section ahead that can realize regenerative charging, but the vehicle power has been depleted and cannot drive to the road section, resulting in low utilization rate of regenerative charging function and poor driving experience of the user.

[0052] Therefore, the embodiment of the present application provides a control method of a new energy vehicle, which can automatically divide a navigation planning route into driving sections and regenerative charging sections, and calculate target consumed electric quantity corresponding to driving at a rated power on each driving section, and automatically limit output power when it is found that the vehicle may have insufficient electric quantity on a driving section, so as to improve the probability of the vehicle entering a regenerative charging section, thereby effectively improving the utilization rate of the regenerative charging function of the new energy vehicle, and making the vehicle travel a longer distance without power failure as much as possible, thereby improving the driving experience of the user.

[0053] Please refer to Figure 1 , Figure 1 is a flowchart of a control method of a new energy vehicle provided by the embodiment of the present application, referring to Figure 1 , the control method of the new energy vehicle includes but is not limited to:

[0054] Step 110, obtaining a navigation planning route of the new energy vehicle;

[0055] In this step, when the new energy vehicle is controlled, first, the navigation planning route thereof can be obtained. Specifically, here, the navigation planning route refers to a vehicle travel route between a starting location at the beginning of navigation and a destination set by a user. In the embodiment of the present application, the navigation planning route of the new energy vehicle is obtained, which aims to combine the control of the new energy vehicle with navigation, and utilize the road conditions and uphill and downhill situations on the route to assist in optimizing the operation of the new energy vehicle, so that the new energy vehicle can effectively utilize the regenerative charging function with a higher probability, and reduce the occurrence of a situation that the regenerative charging function cannot be achieved. It can be understood that in the embodiment of the present application, the navigation planning route can provide explicit geographic location information, based on which the location of each location on the route can be clearly understood, and more geographic information such as altitude and distance between different locations can be obtained. Compared with letting the driver of the vehicle judge the distance and the selection of the route by himself, automatic navigation planning can greatly save time, and is more friendly to novice drivers and users unfamiliar with the road conditions.

[0056] It should be noted that in the embodiment of the present application, the specific way of obtaining the navigation planning route can be flexibly selected according to requirements, and the present application does not limit this. For example, in some embodiments, the process can be implemented based on the following flow:

[0057] In response to a navigation request of the user, obtaining starting point information and terminal point information input by the user;

[0058] Sending the starting point information and the terminal point information to a navigation server, receiving and displaying candidate planning routes returned by the navigation server;

[0059] In response to a selection operation of the user on the candidate planning route, the navigation planning route is obtained.

[0060] In the embodiments of the present application, the navigation planning route can be obtained based on the interaction between the user and the navigation server. For example, when the user (such as a driver) has a navigation demand, a navigation request can be initiated on the center screen of the car, and then the starting point information and the end point information that the user wants to reach are input. The car sends the starting point information and the end point information to the navigation server. After receiving the starting point information and the end point information, the navigation server can automatically generate some recommended routes, which can be recorded as candidate planning routes. Then, the navigation server can send the candidate planning routes back to the car, and the car can display the candidate planning routes on the center screen. Then, the user can select a route from the candidate planning routes according to his own preferences and specific needs, and the selected route is used as the navigation planning route obtained in this navigation.

[0061] It should be noted that in the embodiments of the present application, the interaction mode between the car and the user is not limited. For example, in some embodiments, the center screen of the car can be set as a touch screen, and at this time, the user's clicking, touching, sliding, etc. can be regarded as initiating a request or performing some operations. In other embodiments, the car can also be built-in with a voice recognition interaction function, and at this time, the user can directly realize the initiation of a request or the selection of a candidate planning route through voice, and the embodiments of the present application do not repeat them here.

[0062] In step 120, according to the altitude information of each location on the navigation planning route, driving sections and regenerative charging sections on the navigation planning route are determined, and target consumption electric quantities corresponding to the new energy vehicle running at a rated power on each driving section are calculated.

[0063] In this step, after obtaining the navigation planning route, the altitude information of each location on the navigation planning route can be further obtained. Furthermore, according to the altitude information of each location, the driving sections and the regenerative charging sections on the navigation planning route can be determined. Here, the driving section refers to a section on which the new energy vehicle needs to rely on energy output to travel, generally including flat ground and uphill sections; the regenerative charging section refers to a section on which the new energy vehicle can obtain energy supplement through reverse charging by braking, generally being a downhill section. Specifically, the two kinds of sections can be accurately divided based on the ups and downs of different locations on the route.

[0064] In this step, after the driving section is determined, the target consumption power of the new energy vehicle running at the rated power on each driving section is also calculated. Here, the target consumption power corresponding to the driving section is the power consumed by the new energy vehicle running at the rated power from the starting position to the end position of the driving section. When calculating the target consumption power, first, the length information and the altitude change information of the driving section can be obtained based on the geographic position information, and then the target consumption power can be determined based on the rated power according to the length information and the altitude change information. Specifically, for example, the power consumed by the car running at the rated power under different slopes can be simulated through multiple tests, and then for a certain driving section, the slope thereof can be determined according to the length information and the altitude change information, and the target consumption power can be determined based on the length ratio relationship between the driving section and the test simulation. Of course, it should be noted that for a driving section with a large change in slope, it can be further subdivided into multiple sections, and the power consumption of each part is calculated to obtain the target consumption power.

[0065] Step 130, when the new energy vehicle enters the driving section, the current remaining power of the new energy vehicle is obtained.

[0066] In this step, when the new energy vehicle enters the driving section during the driving process of the new energy vehicle, the current remaining power of the new energy vehicle is obtained. It can be understood that for the new energy vehicle, in the driving section, it needs to output power to supply the car to run, and the total amount of power is in a state of consumption and reduction; while in the regenerative charging section, the car charges the battery pack in reverse, and the total amount of power is in a state of increase. Therefore, if the new energy vehicle runs out of power and cannot continue to run, it is generally in the driving section. Therefore, in the embodiments of the present application, the current remaining power can be detected and obtained each time the new energy vehicle enters the driving section, and based on the remaining power, it can be intuitively understood whether the current new energy vehicle may have a power shortage.

[0067] Step 140, if the target consumption power corresponding to the driving section is greater than the remaining power, the output power of the new energy vehicle is limited to below the rated power.

[0068] In this step, after obtaining the current residual power of the new energy vehicle, the target consumption power corresponding to the driving section and the residual power can be compared. It can be understood that if the target consumption power corresponding to the driving section is greater than the residual power, it means that the new energy vehicle needs to travel the current driving section, and the target consumption power consumed by running at the rated power is relatively large, and the current residual power is insufficient to maintain the new energy vehicle to travel to the next regenerative charging section. Conversely, if the target consumption power corresponding to the driving section is less than the residual power, it means that the new energy vehicle needs to travel the current driving section, and the target consumption power consumed by running at the rated power is relatively small, and the current residual power can maintain the new energy vehicle to travel to the next regenerative charging section.

[0069] Correspondingly, if the target consumption power is greater than the residual power, the current residual power is insufficient to maintain the new energy vehicle to travel to the next regenerative charging section, and in the embodiment of the application, the output power of the new energy vehicle can be limited to below the rated power, such as limiting the use of some video and audio playing functions of the central control screen, or limiting the temperature of the air conditioner, the brightness of the atmosphere lamp, etc., that is, reducing the consumption of electric energy in the new energy vehicle, so as to as far as possible apply electric energy to driving, support the vehicle to travel a longer distance, thereby improving the probability of the new energy vehicle traveling to the next regenerative charging section. It can be understood that since the new energy vehicle can supplement electric energy again on the regenerative charging section, and the electric energy consumed on this section itself can also be obtained based on regeneration, therefore, the scheme provided in the embodiment of the application can make the vehicle travel a longer distance without power failure as far as possible, improve the utilization rate of the regenerative charging function of the new energy vehicle and the cruising distance, thereby facilitating to improve the driving experience of the user.

[0070] Of course, it needs to be explained that in the embodiment of the application, if the target consumption power is less than or equal to the residual power, the current residual power can maintain the new energy vehicle to travel to the next regenerative charging section, then the working power of the vehicle does not need to be limited, and it can run at the rated power. Similarly, if the vehicle is currently in the regenerative charging section, the output power of the new energy vehicle can also be adjusted to the rated power, and in the case of sufficient electric energy, the interference to the user using the related functions of the vehicle is reduced.

[0071] It can be understood that the control method of the new energy vehicle provided in the embodiments of the present application can automatically divide the navigation planning route into driving road segments and regenerative charging road segments, and calculate the target power consumption corresponding to the rated power operation on each driving road segment. When it is found that there is a possibility of insufficient power on a certain driving road segment, the output power is automatically limited to improve the probability of the vehicle entering the next regenerative charging road segment. In this way, the utilization rate of the regenerative charging function of the new energy vehicle can be effectively improved, and the vehicle can travel a longer distance without power failure as much as possible, thereby facilitating improvement of the driving experience of the user.

[0072] In some embodiments, the driving road segments and the regenerative charging road segments on the navigation planning route are determined according to the altitude information of each location on the navigation planning route, and the method comprises:

[0073] A plurality of target locations are sequentially selected from the navigation planning route, and the distance between two adjacent target locations is less than or equal to a first threshold value;

[0074] If the altitudes of the target locations sequentially increase, the road segment between each target location is determined as a driving road segment, or if the altitudes of the target locations sequentially decrease, the road segment between each target location is determined as a regenerative charging road segment.

[0075] In the embodiments of the present application, when determining the driving road segments and the regenerative charging road segments on the navigation planning route, a location can be selected from the navigation planning route every first threshold value distance, and the location is recorded as a target location. Here, the length of the first threshold value can be flexibly set as needed, for example, it can be set to 5m or 10m, and the present application does not limit this. The distance between two target locations can be the first threshold value, or it can be less than the first threshold value. In this way, a plurality of target locations can be selected, which are sequentially arranged from the starting position to the end position of the navigation planning route. Among them, if the altitudes of the target locations contained in a road segment sequentially increase, it indicates that the road segment is an uphill road segment and belongs to a driving road segment; on the contrary, if the altitudes of the target locations contained in a road segment sequentially decrease, it indicates that the road segment is a downhill road segment and belongs to a regenerative charging road segment. Of course, there is also a road segment in which the altitudes of the target locations contained therein are basically unchanged, and this road segment also belongs to a driving road segment, which will not be described herein.

[0076] In some embodiments, the method further comprises:

[0077] detect a highest elevation section in the navigation planning route, wherein an elevation difference between each location in the highest elevation section is less than a second threshold, and an elevation of each location in the highest elevation section is greater than an elevation of each location in other sections of the navigation planning route;

[0078] limit an output power of the new energy vehicle to below the rated power when the new energy vehicle enters the highest elevation section.

[0079] In some cases, such as a mountain climbing section, there can be a flat road after the vehicle reaches the highest peak, and then the road is mainly downhill. In this case, it is relatively more wasteful if the user consumes all the power before going downhill. Therefore, in the embodiments of the present application, the highest elevation section in the navigation planning route can be detected. Here, the highest elevation section refers to the relatively highest part of the entire navigation planning route, the elevation difference between each location in this part is less than a second threshold, that is, the overall is at a higher level, and the change range is small, and the elevation of each location in the highest elevation section is greater than the elevation of each location in other sections of the navigation planning route.

[0080] In the embodiments of the present application, when it is determined that the new energy vehicle enters the highest elevation section, the output power of the new energy vehicle is limited to below the rated power, so as to make the user drive out of the highest elevation section as much as possible, convert the gravitational potential energy of the vehicle into electrical energy, and improve the utilization rate of energy.

[0081] The embodiments of the present application also provide a control system of a new energy vehicle, the system comprising:

[0082] a first acquisition unit configured to acquire a navigation planning route of the new energy vehicle;

[0083] a processing unit configured to determine driving sections and regenerative charging sections on the navigation planning route according to elevation information of each location on the navigation planning route, and calculate target consumed power of the new energy vehicle running at a rated power on each driving section;

[0084] a second acquisition unit configured to acquire a current remaining power of the new energy vehicle when the new energy vehicle enters the driving section;

[0085] a limiting unit configured to limit an output power of the new energy vehicle to below the rated power if the target consumed power of the driving section is greater than the remaining power.

[0086] Further, the processing unit is specifically configured to:

[0087] Multiple target locations are selected sequentially from the navigation planning route; the distance between two adjacent target locations is less than or equal to a first threshold.

[0088] If the altitude of each of the target locations increases sequentially, the road segment between each of the target locations is determined as a driving road segment; or, if the altitude of each of the target locations decreases sequentially, the road segment between each of the target locations is determined as a regenerative charging road segment.
