A self-inspection vehicle lamp control method based on can bus

Abstract

The invention discloses a CAN bus-based self-inspection type vehicle lamp control method, which belongs to the technical field of external vehicle lamps. A CAN bus-based self-inspection type vehicle lamp control method includes the following process: a pressure sensor detects the lamp in real time The pressure signal of the shell, when the shell of the lamp is covered with snow, the pressure sensor detects the abnormal pressure signal, and transmits the abnormal pressure signal to the car body control system through the CAN bus, when the car body control system detects that the pressure signal is abnormal , the car body control system outputs a control signal and transmits it to the driving motor through the CAN bus, and the driving motor works for automatic snow removal. It can realize the automatic snow removal and deicing operation of the external vehicle lamps in snowy weather by using the CAN bus and the vehicle body control system, avoiding snow or ice from affecting the normal use of the vehicle lamps, and effectively prolonging the service life of the external vehicle lamps.

Description

technical field [0001] The invention relates to the technical field of external vehicle lamps, and more specifically relates to a CAN bus-based self-inspection type vehicle lamp control method. Background technique [0002] Cars are driven by power and have 4 or more wheels, non-track-bearing vehicles, mainly used to carry people and (or) goods; tow vehicles that carry people and (or) goods. Lamps are a very important part of a car. Different types of lamps have different functions and effects. At present, many cars need to use external car lamps placed on the roof. [0003] When the external vehicle lighting is used in low temperature areas, it is easy to be covered by ice and snow, fallen leaves or the mixture of the two. After covering, it not only affects the normal use of the external vehicle lighting, but also tends to freeze on the surface of the external vehicle lighting. For a car with a taller body, the ice on the surface of the lamp housing is more difficult to r...

[0003] When the external vehicle lighting is used in low temperature areas, it is easy to be covered by ice and snow, fallen leaves or the mixture of the two. After covering, it not only affects the normal use of the external vehicle lighting, but also tends to freeze on the surface of the external vehicle lighting. For a car with a taller body, the ice on the surface of the lamp housing is more difficult to remove and will damage the lamp housing. For lamps with a higher installation position, it is also difficult to remove snow and ice
