Example Embodiment

[0045] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment of various embodiments of the present invention.

[0046] The present invention drives and controls the daytime running lights through the body controller BCM (Body Control Module) without adding new control modules and driving modules; at the same time, to meet the requirements of EU regulations and take into account the customer’s usage habits, In view of the distinction between automatic gear and manual gear on vehicles currently on the market, the daytime running light control logic is also divided into two solutions: automatic gear control logic and manual gear control logic:

[0047] 1. Daytime running lights control logic of vehicles with automatic transmission

[0048] 1. The engine has been started;

[0049] 2. The headlights are not lit (the headlights include high beam and low beam);

[0050] 3. The gearbox is not in P or N gear;

[0051] 4. T...

Abstract

The invention relates to a daytime driving light control system and a control method thereof. An engine work signal, an electronic parking signal, and an automatic gear box gear signal are received bya high-speed CAN network; and then according to the signals and the work state of a headlight, as well as the control logic of the daytime driving light, a vehicle body controller decides whether todrive the daytime driving light to work normally and simultaneously sends out corresponding working instruction signals of the daytime driving light to a combination meter by a low-speed CAN network.

Description

technical field [0001] The present invention relates to the control strategy of the lighting system when the car is running in the daytime, and in particular to a daytime running light control system and its control method. It is safe and more energy-efficient than the currently commonly used vehicle lighting systems. Background technique [0002] In order to improve the safety of traffic roads, the European Commission (EC) decided to introduce dedicated daytime running lights for various motor vehicles from 2011: new models of cars and vans launched after February 7, 2011 must be equipped with daytime running lights. The start date for running lights, trucks and buses is August 2012. The new standard stipulates that the daytime running lights should be turned on automatically after the vehicle engine is started. After dark, when the driver manually turns on the conventional lighting headlights, the headlights will automatically go out accordingly. [0003] According to r...
