Embodiment 1

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

[0056] Step 101: The controller acquires 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 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 respectively 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;

Abstract

The invention discloses a method and a system for controlling a heater of an electric vehicle, belonging to the technical field of communication networks. The method includes: the controller obtains the vehicle data of the electric vehicle; the controller determines whether the heater of the electric vehicle needs to be turned on according to the vehicle data; 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 , and obtain 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 local area interconnection network LIN message respectively; The first position, the second position and the third position generate a first LIN message; the controller sends the first LIN message to the heater; the heater performs heating according to the first LIN message. The invention realizes the automatic heating function of the heater through the local interconnection network LIN, and improves the safety of automobile driving.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a method and system for controlling a heater of an electric vehicle. Background technique [0002] Electric vehicles are popular due to their advantages of low fuel consumption and less pollution. With the popularity of electric vehicles, the safety and comfort of electric vehicles have become two hot topics for discussion. Safety 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 attention of technicians in the field of communication network technology. [0003] At present, if the driver of the electric vehicle wants to turn on the heater while driving the electric vehicle, he can only turn on the switch of the heater manually, and t...
