In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is to be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with one another without conflict.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.
Before describing the methods provided by the embodiments of the present application, some background techniques related to the present application will be briefly described.
Currently, with the increasing demand for environmental protection, the development of new energy vehicles (pure electric vehicles and hybrid electric vehicles) related technologies is also becoming more and more advanced. The new energy automobile generally comprises an electric driving device and has the characteristic of quick dynamic response, so that the new energy automobile is suitable for intelligent auxiliary driving and unmanned driving applications such as self-adaptive cruising, driving correction, agile navigation and the like, and is popular with wide users.
In the related art, part of new energy automobiles have the function of regenerative charging, which is also called brake energy feedback, namely, the new energy automobiles are braked by utilizing reverse torque generated in the motor braking process, and meanwhile, the vehicle-mounted power battery is charged by reverse electromotive force generated by a motor, and the composite process is the regenerative charging. For example, in some scenes, a user lightly steps on a brake to move down a mountain road with a moderate gradient, and in the process, the new energy automobile can be charged, so that the energy utilization rate is improved. However, in practical application, it is found that, because the user may know less about road conditions and conditions of ascending and descending the route, it is difficult to effectively utilize the regenerative charging function, for example, there may be a road section with a better front part to realize regenerative charging, but the automobile has already been exhausted and cannot travel to the road section, resulting in low utilization rate of the regenerative charging function and poor driving experience of the user.
In view of this, the embodiment of the application provides a control method for a new energy automobile, which can automatically divide a navigation planning route into a driving road section and a regenerative charging road section, calculate target power consumption corresponding to rated power running on each driving road section, and automatically limit output power when finding that the automobile may have insufficient power on a certain driving road section, so as to improve the probability of the automobile driving into the next regenerative charging road section. Therefore, the utilization rate of the regenerative charging function of the new energy automobile can be effectively improved, and the automobile can travel a longer distance under the condition of uninterrupted power as far as possible, so that the driving experience of a user is improved.
Referring to fig. 1, fig. 1 is a flow chart of a control method of a new energy automobile according to an embodiment of the present application, and referring to fig. 1, the control method of the new energy automobile includes, but is not limited to:
in the step, when the new energy automobile is controlled, firstly, the navigation planning route of the new energy automobile can be acquired. Specifically, here, the navigation planning route refers to a vehicle driving route between a new energy vehicle and a place at the beginning of navigation according to a destination set by a user. In the embodiment of the application, the navigation planning route of the new energy automobile is obtained, the purpose is to combine the control and navigation of the new energy automobile, the condition of road conditions and upward and downward slopes of the route is utilized, the operation of the new energy automobile is assisted and optimized, the automobile can effectively utilize the regeneration charging function with higher probability, and the occurrence of the condition that the road section capable of realizing regeneration charging cannot be reached is reduced. It can be appreciated that in the embodiment of the present application, the navigation planning route may provide explicit geographic location information, and based on the navigation planning route, the location of each place on the route may be clearly known, so that more geographic information, such as altitude, distance between different places, etc., may be obtained. Compared with the selection of the distance and the road section which are judged by the automobile driver, the automatic navigation planning can greatly save time, and the method is more friendly for users who are new drivers and are unfamiliar with road conditions.
It should be noted that, in the embodiment of the present application, a specific way for obtaining the navigation planning route may be flexibly selected according to the requirement, which is not limited in the present application. For example, in some embodiments, the process may be implemented based on the following flow:
responding to a navigation request of a user, and acquiring starting point information and end point information input by the user;
the starting point information and the end point information are sent to a navigation server, and candidate planning routes transmitted back by the navigation server are received and displayed;
and responding to the selection operation of the user on the candidate planned route, and obtaining the navigation planned route.
In the embodiment of the application, the navigation planning route can be obtained based on the interaction between the user and the navigation server. For example, when a user (such as a driver) has a navigation request, a navigation request may be initiated on a central control screen of the automobile, and then the current start point information and the destination point information to be reached are input. The car sends the starting point information and the destination point information to the navigation server, the navigation server can automatically generate some recommended routes after receiving the starting point information and the destination point information, the routes can be recorded as candidate planned routes, then the navigation server can send the candidate planned routes back to the car, and the car can display the candidate planned routes on the central control screen after receiving the candidate planned routes. Then, the user can select a route from the candidate planned routes according to the preference and specific requirements of the user, and the selected route is used as the navigation planned route obtained in the navigation.
It should be noted that, in the embodiments of the present application, the interaction manner between the automobile and the user is not limited, for example, in some embodiments, the central control screen of the automobile may be set as a touch screen, and at this time, clicking, touching, sliding, etc. of the user may be regarded as initiating a request or performing some operations. In other embodiments, the vehicle may also have a voice recognition interaction function, where the user may directly initiate a request or select a candidate planned route through voice, which is not described herein in detail.
in this step, after the navigation planning route is obtained, altitude information of each location on the navigation planning route can be further obtained. And the driving road section and the regeneration charging road section on the navigation planning route can be determined according to the altitude information of each place. Here, the driving road section refers to a road section where a new energy automobile needs to be supplied for driving by means of energy output when driving, and generally includes a flat ground and an uphill road section; the regenerative charging road section refers to a road section which can be used for obtaining energy supplement through braking reverse charging when a new energy automobile runs, and is generally a downhill road section. Specifically, the two road sections can be accurately divided based on the ascending and descending conditions of different places on the route.
In the step, after the driving road sections are determined, the target power consumption corresponding to the operation of the new energy vehicle on each driving road section with rated power is also calculated. When the target power consumption is calculated, firstly, the length information and the altitude change information of the driving road section can be obtained based on the geographic position information, and then the target power consumption can be determined based on the rated power according to the length information and the altitude change information. Specifically, for example, the electric quantity consumed by the automobile running at rated power under different gradients can be simulated through multiple tests, then for a certain driving road section, the gradient of the automobile can be determined according to the length information and the altitude change information, and the target electric quantity consumed is determined based on the length proportion relation between the driving road section and the test simulation. Of course, it should be noted that, for a driving road section with a large change in gradient, it may be further subdivided into a plurality of road sections, and the power consumption of each portion is calculated and summed to obtain the target power consumption.
130, when the new energy automobile enters the driving road section, acquiring the current residual electric quantity of the new energy automobile;
in the step, when the new energy automobile is determined to drive into the driving road section in the running process of the new energy automobile, the current residual electric quantity of the new energy automobile is obtained. It can be understood that, for a new energy automobile, in a driving section, the new energy automobile needs to output electric energy to supply the automobile for running, and the total amount of the electric energy is in a state of consumption and reduction; and in the regenerative charging section, the vehicle reversely charges the battery pack, and the total amount of electric energy is in an increased state. Therefore, if the new energy automobile runs out of the electric quantity and cannot continue running, the new energy automobile is generally located in the driving road section. Therefore, in the embodiment of the application, the current residual electric quantity can be detected and obtained when the new energy automobile enters the driving road section every time, and whether the current new energy automobile possibly has the condition of insufficient electric quantity can be intuitively known based on the residual electric quantity.
And 140, limiting the output power of the new energy automobile to be below the rated power if the target consumed electric quantity corresponding to the driving road section is larger than the residual electric quantity.
In this step, after the current remaining power of the new energy automobile is obtained, the target power consumption corresponding to the driving road section and the remaining power can be compared. It can be understood that if the target power consumption corresponding to the driving road section is greater than the remaining power, it indicates that the new energy automobile is about to run on the current driving road section, and the target power consumption required to be consumed for running at the rated power is greater, and the current remaining power is insufficient to maintain the new energy automobile running on the next regenerative charging road section. Otherwise, if the target power consumption corresponding to the driving road section is smaller than the residual power, the new energy automobile is required to run on the current driving road section, the target power consumption required to be consumed for rated power running is smaller, and the current residual power can maintain the new energy automobile to run on the next regenerative charging road section.
Correspondingly, if the target power consumption is greater than the residual power, the current residual power is insufficient to maintain the new energy automobile to travel to the next regeneration charging road section, in the embodiment of the present application, the output power of the new energy automobile can be limited below the rated power, for example, the use of some video playing functions of the central control screen is limited, or the temperature of the air conditioner is limited, the brightness of the atmosphere lamp is reduced, that is, the consumption of electric energy in the new energy automobile is reduced, so that the electric energy is applied to the traveling drive as much as possible, the distance that the automobile travels is supported, and the probability that the new energy automobile travels to the next regeneration charging road section is improved. It can be appreciated that, because the new energy automobile can supplement electric energy again on the regeneration charging road section, and the electric energy consumed by the road section itself can also be obtained based on regeneration, the scheme provided in the embodiment of the application can make the automobile travel farther under the condition of no power failure as far as possible, and improve the utilization rate and the cruising distance of the regeneration charging function of the new energy automobile, thereby being beneficial to improving the driving experience of users.
Of course, it should be noted that, in the embodiment of the present application, if the target power consumption is less than or equal to the remaining power, when the current remaining power can maintain the new energy automobile to travel to the next regenerative charging section, the working power of the automobile is not limited, and the automobile is operated according to the rated power. Similarly, if the automobile is currently in the regenerative charging road section, the output power of the new energy automobile can be adjusted to the rated power, and the interference on the use of the related functions of the automobile by a user is reduced under the condition of more abundant electric energy.
It can be understood that, according to the control method for the new energy automobile provided by the embodiment of the application, the navigation planning route can be automatically divided into the driving road section and the regeneration charging road section, the target power consumption corresponding to rated power operation on each driving road section is calculated, and when the condition that the automobile possibly has insufficient power on a certain driving road section is found, the output power is automatically limited, so that the probability of the automobile driving into the next regeneration charging road section is improved. Therefore, the utilization rate of the regenerative charging function of the new energy automobile can be effectively improved, and the automobile can travel a longer distance under the condition of uninterrupted power as far as possible, so that the driving experience of a user is improved.
In some embodiments, the determining the driving road segment and the regenerative charging road segment according to the altitude information of each location on the navigation planning route includes:
sequentially selecting a plurality of target sites from the navigation planning route; the distance between two adjacent target sites is smaller than or equal to a first threshold value;
and if the altitude of each target place is increased in sequence, determining the road sections among the target places as driving road sections, or if the altitude of each target place is reduced in sequence, determining the road sections among the target places as regeneration charging road sections.
In this embodiment of the present application, when determining the driving road segment and the regenerative charging road segment on the navigation planning route, specifically, a location may be selected from the navigation planning route at intervals of a first threshold value, and recorded as the target location. Here, the length of the first threshold may be flexibly set as required, for example, may be set to 5m or 10m, etc., which is not limited in this application. The distance between the two target points may be the first threshold or less than the first threshold. In this way, a plurality of target sites can be selected and obtained, and the target sites are sequentially arranged from the starting position to the end position of the navigation planning route. Wherein if the altitude of the target site included in which section of road is sequentially increased, it is indicated that the section is an ascending road section, belonging to the driving section; on the contrary, if the altitude of the target place included in which road section is descending in turn, the road section is in the downhill road section, and belongs to the regenerative charging road section. Naturally, there is also a substantially constant altitude of the destination point comprised in the road section, which also belongs to the driving road section, which is not described in detail here.
In some embodiments, the method further comprises:
detecting the highest elevation road section in the navigation planning route; the altitude difference of each place in the highest elevation road section is smaller than a second threshold value, and the altitude of each place in the highest elevation road section is larger than the altitude of each place in other road sections of the navigation planning route;
and limiting the output power of the new energy automobile to be below the rated power when the new energy automobile enters the highest-altitude road section.
In some cases, for example, a mountain climbing road section may have a flat road after the automobile reaches the peak, and the following road section is mainly a downhill road. In this case, if the user consumes power before going down the hill, it is relatively more pleasant. Therefore, in the embodiment of the present application, the highest elevation road segment in the navigation planning route may be detected, where the highest elevation road segment refers to a portion of the route that is relatively highest in the entire navigation planning route, the altitude difference of each location in the portion of the route is smaller than the second threshold, that is, the whole is at a higher level, the variation range is smaller, and the altitude of each location in the highest elevation road segment is greater than the altitude of each location in other road segments of the navigation planning route.
In the embodiment of the application, when the fact that the new energy automobile enters the highest elevation road section is determined, the output power of the new energy automobile is limited below rated power, so that a user enters the highest elevation road section as much as possible, gravitational potential energy of the automobile is converted into electric energy for use, and the utilization rate of energy is improved.
The embodiment of the application also provides a control system of the new energy automobile, which comprises:
the first acquisition unit is used for acquiring a navigation planning route of the new energy automobile;
the processing unit is used for determining a driving road section and a regenerated charging road section on the navigation planning route according to the altitude information of each place on the navigation planning route, and calculating target consumed electric quantity corresponding to the operation of the new energy automobile at rated power on each driving road section;
the second acquisition unit is used for acquiring the current residual electric quantity of the new energy automobile when the new energy automobile enters the driving road section;
and the limiting unit is used for limiting the output power of the new energy automobile to be lower than the rated power if the target power consumption corresponding to the driving road section is larger than the residual power.
