Emergency control apparatus of motor-vehicle light circuit

Abstract

The invention relates to a lamplight circuit emergency control device for a motor vehicle, which belongs to the technical field of mechanism and electron and is particularly used for monitoring and controlling the lamplight circuit of the motor vehicle. The device consists of an alarm emergency circuit, a monitoring and control circuit and a connecting terminal, wherein the connecting terminal is used for electrically connecting both ends of a fuse of the lamplight circuit to be monitored, both ends of a vehicle lamp (or a relay coil of the vehicle lamp), and both ends of a switch of another vehicle lamp used as an emergency lamp respectively; the alarm emergency circuit is used for displaying alarm and controlling the emergency lamp; the monitoring and control circuit is used for controlling the alarm emergency circuit; when a switch of the lamplight circuit to be monitored is switched on, the alarm emergency circuit alarms to indicate that the lamplight circuit to be monitored has a fault, and a circuit of the emergency lamp is switched on and the emergency lamp has an emergency function; and when the switch of the lamplight circuit to be monitored is switched off, the device does not work. The device is connected with the lamplight circuit conveniently and can be used in lamplight circuits of various motor vehicles. When a position lamp is selected as the emergency lamp, a meter lamp and a switch lighting lamp have an obvious alarm function.

Description

technical field [0001] The invention relates to a control device for a light circuit of a motor vehicle, which belongs to the technical field of machinery and electronics, and is especially used for the monitoring and control of the light circuit of a motor vehicle. Background technique [0002] In order to improve driving and work safety, automobiles, tractors, motorcycles and other motor vehicles are equipped with lighting systems to realize lighting and signal functions. In order to make the driver find faults such as light circuit disconnection in time, at present, people have invented some car light circuit detection devices, but there are corresponding deficiencies, which have affected popularization and application. [0003] Chinese patent CN 2167378Y with an application date of May 31, 1993 discloses an "automatic monitoring and display device for automotive lighting circuits", which consists of a housing, a panel and a monitoring and displaying circuit. The monitori...

Problems solved by technology

This control method cannot distinguish whether it is an open circuit fault caused by the insurance or the lamp; once the electronic control module has a fault such as an open circuit, the lamp will not work normally; , are all connected to the parking light circuit, so that the parking light is always on, which cannot simulate the brake signal function of "the brake switch is turned on and the brake light is on".
