Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the description of the present invention, it should be noted that, unless otherwise explicitly stated or limited, the terms "mounted" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; either directly or indirectly through intervening media, either internally or in any combination thereof. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1, the present invention provides a steering water lamp fault handling system, including:

the control unit 1 is electrically connected with the steering flowing water lamp 3, and is used for reading the fault sign state of the steering flowing water lamp 3 and marking a fault signal;

and the alarm unit 2 is electrically connected to the control unit 1, and prompts a fault signal according to the control of the control unit 1.

In a specific embodiment of the present invention, as shown in fig. 2, the control unit 1 is configured to read the state of the fault flag as follows: if the fault flag is 1, the steering water-flowing lamp 3 is turned on in the previous turn-on cycle of the steering water-flowing lamp 3, the steering water-flowing lamp 3 is turned on in the current turn-on cycle, and whether the current turn-on cycle of the steering water-flowing lamp 3 has a fault is detected; if the fault flag is not 1, the steering water lamp 3 normally executes the water running mode, and detects whether a fault occurs in the lighting cycle of the steering water lamp 3 this time.

Further, the control unit 1 is configured to, if it is detected that the steering water lamp 3 in the current lighting cycle has a fault, set a fault flag to 1, and control all the steering water lamp 3 to be turned off, and the control unit 1 controls the alarm unit 2 to prompt a fault signal; if it is detected that the turn water lamp 3 in the current lighting cycle has no fault, the fault flag is 0, and the control unit 1 controls all the turn water lamps 3 to keep operating.

The following describes a fault processing procedure in one lighting cycle of a steering flow lamp fault processing system according to the present invention with reference to a flowchart shown in fig. 2:

in the current lighting cycle, the control unit 1 first reads the state of the fault flag in the previous lighting cycle:

firstly, if the fault flag in the last lighting cycle read by the control unit 1 is 1, the control unit considers that a fault occurs in the last lighting cycle, and then turns on all the steering flowing water lamps 3 in the current lighting cycle;

next, the turn-to-flow lamp 3 in the current lighting cycle is detected again to determine whether there is still a failure: if the control unit 1 detects no fault, the mark fault mark is 0, and the steering running water lamp 3 can normally execute a normally-on mode; if the control unit 1 detects a fault, the fault flag is marked as 1, the alarm unit 2 gives an alarm, and simultaneously all the steering water lamp lamps 3 are turned off.

As can be seen from this, if the fault flag read by the control unit 1 in the last lighting cycle is 1, in order to avoid the situation that the turn-around water-flowing lamp 3 is partially or completely turned off, the turn-around water-flowing lamp 3 may be fully turned on first, and whether the turn-around water-flowing lamp 3 still has a fault is continuously detected while being turned on. By the aid of the processing mode, the steering water-flowing lamp 3 can be prevented from being partially or completely turned off when the steering water-flowing lamp 3 is detected to be out of order, the attractiveness of the vehicle lamp can be guaranteed, and the situation that when the steering water-flowing lamp 3 is detected to be out of order, the failed part is not turned on, and the failed part is turned on can be avoided, so that the attractiveness of the vehicle lamp is affected.

Secondly, if the fault flag in the last lighting cycle read by the control unit 1 is 0, which indicates that no fault exists in the last lighting cycle, the steering flowing water lamp 3 normally executes the flowing water mode, and then, the current lighting cycle is continuously detected once, and for the detection result, if a fault is detected, the fault flag is marked to be 1, and meanwhile, the alarm unit 2 gives an alarm and extinguishes all the steering flowing water lamps 3; if no fault exists, the mark fault mark is 0, and the steering flow lamp 3 continues to execute the flow mode.

From the above description, it can be seen that the steering water-flow lamp fault handling system of the present invention has the following advantages: firstly, the control unit 1 in the steering flowing water lamp fault processing system of the present invention will read the fault flag in the last lighting cycle, if the fault flag read by the control unit 1 for the first time is 1, which represents that there is a fault in the last lighting cycle, the control unit 1 will control the steering flowing water lamp 3 to be fully lighted in the current lighting cycle, so that the situation that part of the steering flowing water lamp 3 is not lighted due to the fault detection will not occur, and then the second detection will be performed, if the fault is detected for the second time, the fault flag will be marked as 1, the alarm unit 2 will send out an alarm, and at the same time, the steering flowing water lamp 3 will be fully extinguished; if no fault is detected as a result of the second detection, the previous fault flag is cleared, the fault flag is marked to be 0 again, and the steering flowing water lamp 3 executes a normally-on action mode. Secondly, if the fault flag read by the control unit 1 for the first time is 0, it indicates that there is no fault in the previous lighting cycle, the steering running water lamp 3 in the current lighting cycle normally executes the running water mode, meanwhile, the steering running water lamp 3 is detected for the second time, if the fault is detected for the second time, the fault flag is marked to be 1, the alarm unit 2 gives an alarm, and meanwhile, the steering running water lamp 3 is completely turned off; if no fault is detected as a result of the second detection, the fault flag is continuously marked as 0, and the steering water lamp 3 executes the water flowing mode.

It can be understood that, during the detection process, the control unit 1 may have an inaccurate detection condition due to various reasons, and the steering flowing water lamp fault handling system of the present invention, taking this into account, may default to a condition that the fault flag detected last time is cleared to be 1 under the condition that the second detection is error-free, and ensure the normal operation of the steering flowing water lamp 3. The steering water-flowing lamp fault system can detect the condition that the last fault mark is 1 again, if the fault mark is 1, the control unit 1 can control the alarm unit 2 to give an alarm to a driver to prompt the steering water-flowing lamp 3 to have a fault. If no fault exists in the steering flowing water lamp 3 after the secondary detection, the previous fault mark 1 is cleared, and the fault mark is recorded as 0, so that the follow-up steering flowing water lamp 3 can normally execute normally-on action.

The MCU can accurately, quickly and efficiently preset tasks to achieve an intelligent control function so as to meet the control requirements of the steering flowing water lamp fault processing system, and the control unit can be realized by various mature logic predictions, such as a P L C control language, a C language and the like.

As another preferred embodiment of the present invention, the alarm unit 2 may be a warning lamp capable of giving an alarm indication to the driver when the control unit 1 detects a failure.

In another preferred embodiment of the present invention, the turning water lamp 3 is a front turning water lamp or a rear turning water lamp.

More preferably, the turn water lamp 3 is L ED turn water lamp.

In addition, the invention also provides a vehicle lamp system which comprises the steering flowing water lamp fault processing system according to any one of the technical schemes.

Further, the invention also provides a vehicle, which is provided with the lamp system according to the technical scheme.

As can be seen from the above description, the steering water lamp fault handling system of the present invention includes a control unit 1 and an alarm unit 2, where the control unit 1 is electrically connected to the steering water lamp 3 for reading the fault flag state of the steering water lamp 3 and marking a fault signal; the alarm unit 2 is electrically connected to the control unit 1 and prompts a fault signal according to the control of the control unit 1. According to the steering water-flowing lamp fault processing system, the control unit 1 reads the fault mark, marks the fault mark, and analyzes the fault mark to realize the fault safety processing of the steering water-flowing lamp 3, so that the user experience is better met, the alarm unit 2 can be timely alarmed, and the safety of the steering water-flowing lamp is greatly improved.
