When the passenger car runs, the passenger car can get off only after the key is pulled out, and a driver of the passenger car running at night can pick up things and close the car door only by means of external residual light or a self-provided lighting tool after the key is pulled out, so that the operation is extremely inconvenient.

Disclosure of Invention

The invention aims to solve the technical problem of providing a time delay control method of a passenger car driver lamp aiming at the prior art, and when a driver pulls out a key to get off the car at night, the time delay light is provided to facilitate the driver to pick up things and close the car door.

The technical scheme adopted by the invention for solving the problems is as follows:

compared with the prior art, the invention has the advantages that:

the invention relates to a time delay control method of a passenger car driver lamp, which is characterized in that before a driver pulls out a key at night, time delay brightness is provided to facilitate the driver to pick up things and close a car door, and the structural design is more humanized.

Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

As shown in fig. 1, the delay control system for the driver lamp of the passenger car in the embodiment comprises a first pentagonal relay 1, the first pentagonal relay 1 comprises a first control end anode 1.1, a first control end cathode 1.2, a first normally open input end 1.3, a first normally closed input end 1.4 and a first power output end 1.5, a first control circuit 2 is connected with the positive electrode 1.1 of the first control end, the other end of the first control circuit 2 is connected with an ACC signal (key control signal) 3, the first control terminal cathode 1.2 is connected to GND (wire ground) via a first ground line 4, the first normally open input end 1.3 is connected with a first input line 5, a rocker switch 6 and a vehicle body control module 7 are sequentially arranged on the first input line 5, the first output end 1.5 is connected with an output line 8, and a driver lamp 9 is arranged on the output line 8;

the control system further comprises a second pentagonal relay 10, an illumination switch 11 and a time delay controller 12, wherein the second pentagonal relay 10 comprises a second control end anode 10.1, a second control end cathode 10.2, a second normally open input end 10.3, a second normally closed input end 10.4 and a second power output end 10.5, the illumination switch 11 comprises a first input end 11.1, a first output end 11.2, a second input end 11.3 and a second output end 11.4, the time delay controller 12 comprises a third power input end 12.1, a third power output end 12.2, a signal input end 12.3 and a ground end 12.4, the first input end 11.1 is connected with a passenger car system power supply through a second input line 13, the first output end 11.2 is connected with a GND (wire ground end) through a second ground line 14, the second input end 11.3 is connected with a second control end cathode 10.2 through a first connection line 15, and the second output end 11.4 is connected with a second control end anode 10.1 connection line through a second connection line 16, the second power output terminal 10.5 is connected to the first normally-closed input terminal 1.4 through a third connection line 17, the second normally-closed input terminal 10.4 is connected to the third power output terminal 12.2 through a fourth connection line 18, the third power input terminal 12.1 is connected to the passenger car system power supply through a third input line 19, the signal input terminal 12.3 is connected to an ACC signal (key control signal) 3 through a second control line 20, and the ground terminal 12.4 is connected to GND (wire ground terminal) through a third ground line 21;
