Detailed Description
In order to make the technical problems, technical solutions and advantageous technical effects to be solved by the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Fig. 1 shows a flowchart of a method for controlling charging of a vehicle according to an exemplary embodiment of the present invention. The following exemplary examples describe the method according to the invention in more detail.
As shown in fig. 1, the method may include steps S1 to S3. In step S1, a quick charge demand of the host vehicle is determined based on the battery characteristic parameter of the host vehicle and the travel information of the occupant of the host vehicle. In the present embodiment of the present invention, the present vehicle is especially a vehicle with an automatic driving function, and the vehicle uses a power battery that needs to be periodically charged as a main power source. Here, the battery characteristic parameter, in particular the state of charge parameter, of the power battery of the host vehicle, which can reflect the remaining charge of the power battery of the host vehicle, may be monitored by the battery management unit 12 of the host vehicle. When the state of charge parameter of the power battery is monitored to be lower than a preset threshold value, the charging requirement of the vehicle can be determined.
Meanwhile, the trip information of the occupant of the own vehicle may be acquired by the vehicle-mounted communication unit 11, for example, from a smart phone or a personal database of the occupant of the own vehicle, wherein the trip information may be acquired by the vehicle end only by the authorization of the occupant, so as to protect the personal privacy of the user. Based on the journey information of the passenger, whether an emergency journey requiring the use of the vehicle exists in a next certain period of time can be evaluated, and if the emergency journey is close to the current moment and the journey length is long, the quick-charging requirement of the vehicle can be determined.
Alternatively, the method for controlling the charging of a vehicle according to another exemplary embodiment of the present invention as shown in fig. 2 may further include step S11. In step S11, the quick charge demand of the host vehicle is determined based on a control instruction input by the occupant of the host vehicle. For example, the occupant of the vehicle may input a control instruction regarding the quick charge demand through the human-computer interaction unit 16 in a voice control or touch screen control manner.
After determining the fast charge demand of the own vehicle, in step S2, the fast charge demand and the current position information of the own vehicle are transmitted to the rear end 2, and the own vehicle is controlled to travel to the charging station based on the received position information of the charging station recommended by the rear end 2. Here, after the backend 2 receives the quick charge demand and the current position information of the own vehicle from the in-vehicle communication unit 11, the backend 2 can determine charging stations to be recommended from among the candidate charging stations based on the following criteria: the charging station is closest to the current position of the vehicle and the charging station has a currently available fast charging post, wherein the currently available fast charging post is in particular that the fast charging post has been fully put into operation and no vehicle is charging on the fast charging post at the current moment, although the fast charging post may already have a reserved charging order.
In step S3, when the host vehicle travels close to the charging station, the type of the charging post used by the host vehicle at the charging station is estimated based on the position information of the charging station received from the rear end 2 and the charging time of each charging post of the host vehicle at the charging station, and the host vehicle is controlled to travel to the charging post of the corresponding type of the charging station to perform charging. Step S3 is elaborated below in connection with a workflow diagram of a method for controlling charging of a vehicle according to another exemplary embodiment of the invention shown in fig. 3. Only the differences from the embodiment shown in fig. 1 are explained here, while the same steps are not repeated for the sake of brevity.
As shown in fig. 3, the step S3 may include steps S31 to S35. In step S31, a statistical list of charging stations is created using the position information of the charging stations received from the backend 2 and the charging times of the own vehicle at each charging post of the charging stations. The charging time here includes, in particular, the charging date and the charging time of the vehicle at the respective charging post. And in the set statistical time period, the number of charging moments of the vehicle on a certain charging pile of the charging station is the number of charging times of the vehicle on the corresponding charging pile, so that the use frequency and the charging habit of each charging pile of the charging station are reflected.
In step S32, when the host vehicle travels close to the charging station, it is determined whether the charging station exists in the statistical list based on the position information of the charging station. If the charging station is present in the statistical list, in step S33 it is evaluated whether the probability of the fast charging post of the own vehicle at the charging station is greater than a preset probability threshold based on the charging time of the own vehicle at each charging post of the charging station. In the current embodiment of the present invention, the charging stations may be classified into a fast charging station having a higher charging power and a standard charging station having a lower charging power based on the type of the charging stake. Based on the charge frequency duty cycle of each charging peg in the statistical list, it may be determined whether the host vehicle is more prone to charging using a fast charging peg or a standard charging peg at the charging station.
If the probability of the vehicle traveling to the fast charge stake of the charging station is greater than the preset probability threshold, the vehicle is controlled to travel to the fast charge stake of the charging station for fast charging in step S34. In this case, the image recognition information of the parking space marking of the quick charging post of the charging station can be acquired by the sensor and fusion unit 15, which comprises, for example, a vehicle-mounted camera and its image processing unit, on the basis of which the vehicle is controlled to travel to the respective charging post and to rest in the parking space associated with the respective charging post for quick charging.
If the probability of the fast charging pile of the vehicle at the charging station is not greater than the preset probability threshold, the vehicle is controlled to travel to the standard charging pile of the charging station in step S35 to perform standard charging. Likewise, the image identification information of the parking space flag of the standard charging post with respect to the charging station may be acquired by the sensing and fusing unit 15, and the host vehicle may be controlled to travel to the corresponding charging post and park in the parking space allocated to the corresponding charging post based on the image identification information to perform standard charging.
According to the invention, the quick charge requirement of the vehicle can be automatically determined based on the battery characteristic parameters of the vehicle and the travel information of the passenger of the vehicle, and the corresponding type of charging piles in the charging station are automatically selected to charge based on the charging habit of the passenger, especially, the quick charging piles are automatically selected to charge under the condition that the battery capacity of the vehicle is insufficient and the travel of the passenger is compact, so that the user experience of the charging process of the automatic driving vehicle is effectively improved, and a great amount of time and energy are saved for the passenger.
Fig. 4 shows a workflow diagram of a method for controlling charging of a vehicle according to another exemplary embodiment of the invention. Only the differences from the embodiment shown in fig. 1 are explained below, and the same steps are not repeated for the sake of brevity.
As shown in fig. 4, the method may further include step S4. In step S4, notification information about the selected charging stake is transmitted to an occupant of the host vehicle. The notification information may be sent to the passenger by an in-vehicle voice device, or may be sent to the passenger by a central control display, a head-up display, a dashboard, or the like, to inform the passenger of the currently selected charging stake. In particular, when the currently selected charging pile type does not match the charging pile type desired by the occupant, the occupant may manually input a corresponding control command to make a change.
In addition, it should be noted that the sequence numbers of the steps described herein do not necessarily represent a sequential order, but are merely a reference number, and the order may be changed according to circumstances as long as the technical object of the present invention can be achieved.
Fig. 5 shows a schematic block diagram of a system 1 for controlling the charging of a vehicle according to an exemplary embodiment of the invention.
As shown in fig. 5, the system 1 may comprise the following components:
an in-vehicle communication unit 11 configured to acquire travel information of an occupant of the own vehicle, transmit a quick charge demand of the own vehicle to the rear end 2, and receive recommended position information of a charging station and charging time of the own vehicle at each charging post of the charging station from the rear end 2;
