Embodiment 1

[0049] This embodiment provides a grid control method, such as figure 1 As shown, steps S101, S102, S103, and S104 are included, and each step will be described in detail below.

[0050] In step S101, the collected current grille opening gear is received.

[0051]In step S102, a current grille control strategy corresponding to the current grille opening gear is determined according to the current grille opening gear, wherein the input parameters of each grille control strategy include water temperature, air-conditioning pressure and vehicle speed.

[0052] In step S103, the collected current water temperature, current air-conditioning pressure and current vehicle speed are received.

[0053] In step S104, the current water temperature, the current air-conditioning pressure, and the current vehicle speed are used as values ​​of input parameters of the current grille control strategy to control the grille opening gear.

[0054] In this embodiment, before receiving the collecte...

Embodiment 2

[0067] This embodiment provides a grid control method, such as figure 2 As shown, steps S201, S202, S203, S204, and S205 are included, and each step will be described in detail below.

[0068] In step S201, the corresponding relationship between the grille opening gear and the grille control strategy is stored in advance.

[0069] The corresponding relationship between the grille opening gear and the grille control strategy can be preset by the vehicle manufacturer according to the actual situation of the vehicle and stored in the on-board computer.

[0070] The corresponding relationship between the grille opening gear and the grille control strategy can also be fine-tuned by the user on the central control display screen, for example, according to the user's own driving habits and the climate of the city where the user is located, the grille control strategy Water temperature (the first temperature, the second temperature, the third temperature, the fourth temperature, the...

Embodiment 3

[0097] This embodiment provides a grid control device, such as image 3 As shown, the device includes a relationship storage module 301, a first receiving module 302, a policy determination module 303, a second receiving module 304 and a control module 305, and each module will be specifically introduced below:

[0098] The relationship storage module 301 is configured to pre-store the corresponding relationship between the grille opening gear and the grille control strategy before receiving the collected current grille opening gear.

[0099] The corresponding relationship between the grille opening gear and the grille control strategy can be preset by the vehicle manufacturer according to the actual situation of the vehicle and stored in the on-board computer.

[0100] The corresponding relationship between the grille opening gear and the grille control strategy can also be fine-tuned by the user on the central control display screen, for example, according to the user's own ...

Abstract

The invention provides a grille control method and a device, belonging to the automobile automatic control field, comprising: according to the current grille opening gear, determining the current grille control strategy corresponding to the current grille opening gear, wherein the input parameters of each grille control strategy include water temperature, air conditioning pressure and vehicle speed; receiving the collected current water temperature, current air conditioning pressure and current vehicle speed; taking the current water temperature, the current air conditioning pressure, and thecurrent vehicle speed as the values of input parameters of the current grille control strategy to control the grille opening gear. As the current water temperature and the vehicle speed of the vehicleare not only taken into account when the grille opening gear is controlled and the current air-conditioning pressure of the vehicle is considered, the grille opening is adjusted in real time on the basis of guaranteeing the safe operation of the air-conditioning, so as to ensure the safety of the vehicle and reduce the fuel consumption of the vehicle, so as to avoid damage to the air-conditioningcaused by the high air-conditioning pressure.

Description

technical field [0001] The invention relates to the field of automatic control of automobiles, in particular to a grid control method and device. Background technique [0002] The grille on the car is used to allow outside air to enter the engine compartment. The air that enters is not only used to supply the engine intake, but also to cool the oil. However, if the grille opening is too large, it will increase the warm-up time when the cold car is started in winter. It will also increase the air resistance when the vehicle is running at high speed, which in turn will lead to an increase in the fuel consumption of the vehicle. [0003] Under the current technology, the variable grille can adjust the opening size of the grille in real time according to the current water temperature and speed of the vehicle, so as to adapt to the current working conditions of the vehicle and reduce fuel consumption. [0004] During the process of realizing the present disclosure, the inventors...
