Description

一种汽车转向灯的判断控制系统 Determining a vehicle turn signal control system

技术领域 FIELD

[0001] 本发明涉及汽车照明控制技术,具体涉及一种汽车转向灯的判断控制系统,特别适合于在前后转向灯功率相差很大的情况下使用。 [0001] The present invention relates to automotive lighting control technology, particularly to a vehicle steering control system determines the lamp, particularly suitable for the front and rear turn signals the case of large power difference used.

背景技术 Background technique

[0002] 现有轿车使用的转向灯一般是前、后转向灯各21W,侧转向灯5W,三个转向并联, 在前、后转向灯出现故障的时候需要进行快闪报警。 [0002] Existing steering lamp is generally used in the car before, each of the turn signal 21W, side lights 5W, three parallel steering, front and rear turn lamp failure when the flash is required alarm. 转向灯是否出现故障是由给转向灯供电的控制器根据电流的变化进行判断的。 Whether the turn signal is judged by the failure to turn the lamp power supply controller according to a change in current. 但新的车型越来越多使用LED作为后转向灯光源,LED光源的电流远小于普通光源,一般在5W以内,并且发生故障时不会完全失效,如果部分LED失效,变化的功率可能在1W以内,而此功率已经小于普通转向灯正常使用中的功率误差值,因此,将转向灯按照左、右两边并联在一起时无法正常判断LED光源的故障。 However, the new models more light source LED is used as the steering, the current is much smaller than ordinary LED light source, generally within 5W, and does not fail completely when a fault occurs, if some LED failure, the power may change 1W or less, and this is already less than the ordinary power steering lamp power error value in normal use, therefore, the turn signal lamp according to the left and right sides parallel with the fault can not be determined when the LED light source normally.

发明内容 SUMMARY

[0003] 本发明的目的是提供一种汽车转向灯的判断控制系统,它能对普通转向灯和LED 光源或其它小电流光源混用的车辆的照明进行判断控制,确保汽车转向安全。 [0003] The object of the present invention is to provide a steering control system determines the lamp, which can turn lights LED light source and a current source or other small vehicle mix for ordinary judgment control, steering ensure safety.

[0004] 本发明所述的一种汽车转向灯的判断控制系统,包括控制器,分别与控制器连接的转向灯电源、组合开关和紧急报警开关,其特征是:转向灯电源分为普通灯输出和LED输出; [0004] A steering lamp according to the present invention determines the control system includes a controller, the controller respectively connected to turn the power lamp, the combination switch and emergency alarm switch, wherein: the power is divided into ordinary light flasher LED output and the output;

左普通转向灯通过一个继电器与控制器的普通灯输出连接,左转向LED灯通过一个继电器与控制器的LED输出连接,左普通转向灯与左转向LED灯并联与控制器的左转向选择连接; Normal left turn signal to the controller via a relay output connected to ordinary light, the LED lamp through a left turn relay LED output connected to the controller, the left turn and the left turn signal common LED lamps in parallel and connected to the controller turning to the left;

右普通转向灯通过一个继电器与控制器的普通灯输出连接,右LED转向灯通过一个继电器与控制器的LED输出连接,右普通转向灯与右转向LED灯并联与控制器的右转向选择连接。 Common turn signal lamp output through the right common controller connected to a relay, a right turn signal LED through the LED output controller connected to a relay, a right turn signal and the normal right turn in parallel with the LED lamp controller connected to the right steering choice.

[0005] 所述的一种汽车转向灯的判断控制系统,其特征是:所述的与控制器连接的组合开关分为左转向开关和右转向开关。 Of [0005] determining a vehicle steering control system of the lamp, characterized in that: said switch controller is connected to the combination of steering switch into left and right steering switch.

[0006] 在控制器内制作两个不同判断参数,分别用于判断左、右普通转向灯和左、右LED 转向灯。 [0006] In the production of two different controller parameters is determined, respectively, for determining the left and right turn lamps and general left and right turn signal LED. 开关打到一侧转向时,控制器的两路转向灯电源同时输出,并且这一侧的继电器控制电路有效,选择这一侧的转向灯亮,同时控制器内的判断程序开始分别对普通灯和LED 灯进行判断检测,在发现有失效的时候这一侧转向灯就实施快闪报警。 When the switch to the side of the steering, the turn signal control two power output simultaneously, and the relay control circuit of this active side, this side of the steering selected lights, while the program is determined in the controller for ordinary lamps are started and LED light detection judgment, when the failure found in this embodiment the side turn signal lamp to flash an alarm.

[0007] 本发明和现有技术相比具有以下优点:由于将左普通转向灯与左转向LED灯并联、右普通转向灯与右转向LED灯并联,所以,能对普通转向灯和LED光源或其它小电流光源混用的车辆的照明进行判断控制;由于普通转向灯和LED灯分别由不同的线路输出,所以。 [0007] The prior art and the present invention has the following advantages: Because the left turn and the left turn signal common LED lamps in parallel, a right turn and the right turn signal common LED lamps in parallel, so that the LED light sources can turn signals and ordinary or other illumination sources mix small current vehicle determination control is performed; since normal turn signal lamp and the LED output by different lines, so. 如果发现普通灯或者LED发生故障,控制器的两路驱动电源马上实施快闪报警,从而确保了汽车转向安全。 If found to ordinary light or an LED fails, the controller drives two power supply embodiments flash alarm immediately, thus ensuring the safety steering. 附图说明 BRIEF DESCRIPTION
