Abstract

The invention provides an in-vehicle infotainment machine time calibration method, a calibration system, an in-vehicle infotainment machine and a vehicle. The in-vehicle infotainment machine time calibration method is applied to the in-vehicle infotainment machine of the vehicle, and comprises the steps of: acquiring the instrument time of a vehicle instrument within a time period from the start of the in-vehicle infotainment machine to the failure of cold start of a communication module and a positioning module of the vehicle, and updating current time of the in-vehicle infotainment machine according to the instrument time; when acquiring network time which is obtained by means of the communication module or the positioning module, calculating a time difference value between the current time and the network time, and comparing the time difference value with a preset threshold value; and updating the current time of the in-vehicle infotainment machine according to the network time if the time difference value is not less than the preset threshold value. The in-vehicle infotainment machine solves the problem that a local clock is inaccurate in time due to long-term operation or power failure of a vehicle battery, and effectively ensures that the error time of the in-vehicle infotainment machine can be corrected in time.

Description

technical field [0001] The invention relates to the technical field of vehicle-machine software, in particular to a vehicle-machine time calibration method, a calibration system, a vehicle-machine, and a vehicle. Background technique [0002] Car machine is the abbreviation of in-vehicle infotainment products installed in the car. Most of them are installed in the center console and can display the current time through the display. However, the local clock of the car will be inaccurate due to long-term operation or power failure of the vehicle battery. How to correct the clock information of the car has become one of the concerns of the industry. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a vehicle-machine time calibration method, a calibration system, a vehicle-machine, and a vehicle for solving the above problems in the prior art. [0004] In order to achieve the ab...
