Description
Technical Field
The invention belongs to the technical field of automobile control, and particularly relates to a control method of an automobile combined lamp control system.
Background
The automatic headlight is also called automatic induction type automatic headlight, a photosensitive control system is installed on a front combined lamp of an automobile, and a Body Control Module (BCM) judges the change of light brightness according to a light sensor so as to control the function of automatically turning on or off the headlight. The headlight switch has the advantages that the process of finding the switch is omitted when a driver needs the headlight, the situation that the driver forgets to turn on the headlight at night or when the light is not good can be avoided, and driving safety is improved.
The traditional automobile headlamp function consists of the following components: position light and high and low beam light switches (generally on a combination switch), headlights, and a Body Control Module (BCM). After the function of the automatic headlamp is added, the following changes are brought: the control module of the automatic head lamp is newly added with an automatic head lamp switch (generally on a combined switch), a light sensor and a Body Control Module (BCM). Aiming at a certain type of automobile, the automatic headlamp function is used as a high-matching optional function, and firstly, the principle of a Body Control Module (BCM) needs to be developed again, so that the automatic headlamp function can be matched or not matched at the same time, and the purposes of generalization and cost reduction are achieved. And aiming at the functions of the automatic headlamps or not, two types of combination switches are designed to cover low-distribution and high-distribution vehicle types, the smaller the internal hardware change of the combination switch is, the better the internal hardware change is, and the cost is reduced as much as possible.
In a traditional combination switch, a far light signal and a passing signal are the same signal, the signal meets the requirement without the function of an automatic headlamp, and the BCM is only used as a signal collector to control the output of a corresponding light function. If the automatic headlight configuration is added, the expected output of turning on the high beam and turning on the overtaking under the automatic headlight gear are completely different, so that the BCM must correctly distinguish whether the actual operation of the user is the high beam or the overtaking command. However, in the current signal matching mode, one signal only represents one function, and in order to solve the problem, only the far-beam signal and the overtaking signal can be separated, and a signal is added to the combination switch, so that the combination switch needs to be re-developed, and extra development cost can be generated.
