Embodiment 1

[0055] The embodiment of the present invention provides a method for controlling a heater of an electric vehicle, and the execution body of the method is a controller and a heater, see figure 1 , The method includes:

[0056] Step 101: The controller obtains vehicle data of the electric vehicle, and the vehicle data includes one or more of external environment data, vehicle driving data, and vehicle state data;

[0057] Step 102: The controller determines whether it is necessary to turn on the heater of the electric vehicle according to the acquired vehicle data;

[0058] Step 103: If the heater needs to be turned on, the controller obtains the maximum power of the heater, the target water temperature and the heating enable signal;

[0059] Step 104: The controller obtains the first position, the second position, and the third position of the maximum power, the target water temperature, and the heating enable signal in the LIN message of the local area interconnection network respectiv...

Embodiment 2

[0065] The embodiment of the present invention provides a method for controlling a heater of an electric vehicle, and the execution body of the method is a controller and a heater, see figure 2 , The method includes:

[0066] Step 201: The controller obtains vehicle data of the electric vehicle, and the vehicle data includes one or more of external environment data, vehicle driving data, and vehicle state data;

[0067] The controller mainly adjusts the heater according to vehicle data such as external environment data, car driving data, and car status data. Therefore, in this step, the controller obtains the vehicle data of the electric car. The vehicle data includes external environment data, car driving data, and car data. One or more of the status data.

[0068] The external environment data includes the indoor temperature and outdoor temperature of the electric vehicle; the controller collects the external environment data through the temperature collection device installed on ...

Abstract

The invention discloses a method and system for controlling a heater of an electric automobile, and belongs to the technical field of communication networks. The method comprises the following steps that a controller acquires automobile data of the electric automobile; according to the automobile data, the controller determines whether the heater of the electric automobile needs to be started or not; if the heater needs to be started, the controller acquires maximum power, target water temperature and a heating enable signal of the heater, and separately acquires a first position of the maximum power capacity in a local interconnect network (LIN) message, a second position of the target water temperature in the local interconnect network (LIN) message and a third position of the heating enable signal in the local interconnect network (LIN) message; according to the maximum power capacity, the target water temperature, the heating enable signal, the first position, the second position and the third position, the controller generates a first LIN message; the controller transmits the first LIN message to the heater; and the heater performs heating according to the first LIN message. According to the method and the system disclosed by the invention, the function of automatically heating of the heater is realized by a local interconnect network (LIN), and the driving safety of the automobile is improved.

Description

Technical field [0001] The present invention relates to the technical field of communication networks, in particular to a method and system for controlling heaters of electric vehicles. Background technique [0002] Electric vehicles are popular due to their low fuel consumption and low pollution. With the popularization of electric vehicles, the safety and comfort of electric vehicles have become two hot topics of discussion. Under the condition of meeting certain safety, the comfort of electric vehicles Sex has become a major demand of customers, especially the requirements for heating are getting higher and higher. Therefore, in the cold winter, how to control the heating of the electric vehicle heater and rapidly increase the temperature in the electric vehicle has become the focus of the technical personnel in the field of communication network technology. [0003] At present, when the driver of an electric vehicle is driving the electric vehicle, if he wants to turn on the h...
