Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a flowchart of a thermal management method of an electric vehicle of a vehicle according to an embodiment of the present invention.
As shown in fig. 1, the method for thermal management of an electric vehicle according to an embodiment of the present invention includes the following steps:
in step S101, the current destination of the user is acquired.
As a possible implementation manner, the vehicle may recognize the current destination of the user through a manual input or a voice input of the user, or may recognize the current destination through a target location sent by the mobile terminal of the passenger, that is, the embodiment of the present invention may determine the current destination through various manners, which is not particularly limited.
In step S102, the corresponding thermal management energy consumption in each operation mode is predicted according to at least one recommended navigation route between the current location and the current destination of the user and the current traffic information.
The embodiment of the invention can predict the corresponding thermal management energy consumption of each operation mode under each recommended navigation route by combining the current road condition information.
For example, as shown in fig. 2, when a user inputs that a current destination is beijing city in a navigation system, the navigation system automatically generates a plurality of navigation routes according to the current location and the destination, and sends the navigation routes to the thermal management controller, and the thermal management controller calculates thermal management energy consumptions corresponding to three operation modes in the navigation route according to current road condition information, air conditioner setting temperature, external environment temperature, and the like, for example, energy consumption corresponding to operation mode 1 is about 10kw, energy consumption corresponding to operation mode 2 is about 15kw, and energy consumption corresponding to operation mode 3 is about 20 kw. The operation mode 1 may be a loop shown in fig. 3, the operation mode 2 may be a loop shown in fig. 3, and the operation mode 3 may be a loop shown in fig. 3.
In addition, the embodiment of the invention can generate the suggestions for reducing energy consumption while generating the thermal management energy consumption corresponding to each operation mode. For example, as shown in FIG. 2, the passenger compartment temperature is adjusted up/down, the energy consumption is expected to decrease by 1kW, the vehicle speed is maintained at A km/h, and the energy consumption is expected to decrease by B kW.
In step S103, the corresponding thermal management energy consumption in each operation mode of each recommended route is sent, and when navigation is performed according to the target recommended navigation route selected by the user, the execution component for controlling thermal management based on the target operation mode selected by the user executes a corresponding thermal management action, and the target operation mode is displayed at the vehicle-mounted terminal of the electric vehicle.
It can be understood that, according to the embodiment of the present invention, a user can actively select a thermal management operation mode by referring to the thermal management energy consumption of each operation mode to actively control the thermal management energy consumption, thereby greatly improving the controllability of thermal management and effectively improving the thermal management experience of the user. In addition, the embodiment of the invention can also actively adjust the heat management according to the proposal of reducing the energy consumption so as to further improve the controllability of the heat management and reduce the energy consumption of the heat management.

It should be noted that, the thermal management operation mode control principle of the embodiment of the present invention may be as shown in fig. 4, where each controller sends a respective thermal management demand signal according to a vehicle demand, and the HUT displays a corresponding thermal management operation mode according to the received signal. For example, a VCU (Vehicle control unit) sends a driving system cooling demand signal, and the HUT displays various driving system cooling operation modes according to the received driving system cooling demand signal; for another example, the BMS (Battery Management System) transmits a Battery cooling or heating demand signal, and the HUT displays a plurality of Battery cooling or heating operation modes according to the received Battery cooling or heating demand signal; for another example, an AC (Air Conditioning) transmits an in-vehicle cooling or heating demand signal, and the HUT displays a plurality of in-vehicle cooling or heating operation modes according to the received in-vehicle cooling or heating demand signal.
In some embodiments, displaying the target operation mode at the in-vehicle terminal includes: receiving a thermal management display instruction of a user; and lightening the display mark obtained by the thermal management framework according to the thermal management display instruction, determining the mark mode of the display mark according to the target operation mode of the electric automobile, and displaying the display mark in the mark mode on the vehicle-mounted terminal.
The thermal management structure may be as shown in fig. 5, a display screen interface of the HUT may be designed according to the thermal management structure in the embodiment of the present invention, and taking the thermal management structure shown in fig. 5 as an example, the designed display interface is as shown in fig. 6, it should be noted that the design of the display interface may be set according to specific situations, and is not particularly limited. The embodiment of the invention can also add a Thermal module in the main directory of the HUT, the Thermal module can be displayed as a Thermal button on the display interface, a user can independently select whether to enter the Thermal module, for example, if the user generates a Thermal management display instruction when clicking the Thermal button, a Thermal management architecture picture correspondingly appears, and the Thermal management operation mode is displayed according to the received signals sent by each controller and according to the mark mode.
In this embodiment, the indication mode includes one or more of a color display mode of an operating circuit and a non-operating circuit, a medium flow display mode in the pipeline, a duty ratio of the water pump, and a signal display mode of an actual rotation speed of the compressor.
Taking the operation loop shown in fig. 3 as an example, the marking manner may include: the circuit is not operated, and the internal medium is made to flow in the direction shown in the figure (indicated by the broken line part in the figure), and the duty ratio of the water pump and the rotation speed of the compressor are displayed in real time according to the received signals. And fourthly, setting the refrigerating circuit of the passenger compartment as a circuit corresponding to the operation mode 4.
The method for thermal management of an electric vehicle will be further described with reference to fig. 7, and as shown in fig. 7, includes the following steps:
step S1, inputting the destination in the navigation system by the user;
step S2, the navigation system recommends a navigation route according to the current position and destination of the user;
step S3, the navigation system sends the road condition information to the thermal management controller;
step S4, the thermal management controller calculates thermal management energy consumption, and calculates an operation scheme and an energy consumption reduction suggestion, wherein the operation scheme comprises the thermal management energy consumption of each operation mode under each navigation route;
step S5, sending the operation scheme and the energy consumption reduction suggestion to the navigation system, where an example of the operation scheme and the energy consumption reduction suggestion received by the navigation system may be as shown in fig. 3;
step S6, selecting the operation scheme by the user;
step S7, the navigation system sends the user' S selection intention to the HUT;
in step S8, while the HUT executes the thermal management action according to the operation mode selected by the user, the user may also actively adjust according to the energy consumption reduction advice to reduce the thermal management energy consumption.
In some embodiments, the method of embodiments of the present invention further comprises: obtaining a target comfort intention of a user; and when the target comfort intention is detected to conflict with the current operation working condition of the electric automobile, sending recommendation schemes generated respectively based on the target comfort intention and the current operation working condition, and responding to the target comfort intention or continuing to operate the current operation working condition according to the target recommendation scheme selected by the user.
The target comfort intention may be a comfort intention that the user wants the entire vehicle to achieve. When the target comfort intention current operation working condition conflicts, the embodiment of the invention generates the recommendation scheme, and the user can select the recommendation scheme or continue to operate the current operation working condition, so that the vehicle operation mode actively determined by the user can be ensured, and the user satisfaction is improved while the conflict is eliminated.
