Abstract

The invention provides a crossroad driving reminding method and device and a vehicle. The crossroad driving reminding method comprises the following steps: obtaining the current speed of the vehicle through a vehicle speed sensor, and obtaining distance between the vehicle and a stop line at the current moment through a front camera; obtaining needed passing time according to the current speed of the vehicle and the distance between the vehicle and the stop line at the current moment; when detecting that the traffic light turns from green to yellow, comparing the needed passing time with yellow light time length; and when the comparison result shows that the needed passing time is equal to or larger than the yellow light time length, carrying out brake-reminding operation, and controlling a fuel spray nozzle to stop spraying oil. According to the scheme, the cases of red light mis-running or sudden brake and the like of a driver can be prevented, safety of vehicle driving and taking is improved, and meanwhile, the purpose of saving oil is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method, a device and a vehicle for reminding traffic at an intersection. Background technique [0002] According to Article 26 of the "Road Traffic Safety Law of the People's Republic of China", traffic lights are composed of red lights, green lights, and yellow lights. A red light means no access, a green light means permission to pass, and a yellow light means a warning.
