Vehicle and steering lamp control device thereof

Abstract

The invention provides a vehicle and a steering lamp control device thereof, and the device comprises a power supply circuit which comprises a positive electrode power supply line and a negative electrode power supply line; the input end of the time-delay circuit is connected with the power supply circuit, and the time-delay circuit is used for outputting an enable signal from the output end after being electrified and delaying preset time; the software module is used for outputting an enable signal and a dynamic lightening signal from an output end after being electrified; and the driving circuit is used for driving the steering lamp to be lightened dynamically in a flowing manner when receiving the enable signal and the dynamic lightening signal output by the software module, and driving the steering lamp to be lightened in a flickering manner when only receiving the enable signal output by the time delay circuit. On the premise of meeting functional safety, the dynamic running water effect of the lamp can be achieved through the positive power supply line and the negative power supply line, the requirement of consumers for the dazzling effect can be met, the functional safety of the lamp can be improved, illumination laws and regulations can be met under various working conditions, and industrial development is promoted.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a turn signal control device of a vehicle and a vehicle. Background technique [0002] With the wide application of LEDs in automotive lamps, automotive lamps and lanterns pay more and more attention to visual effects. In addition to the splendid shape and the increase in the number of LED particles, the lighting mode has also changed from a single function independent overall lighting to each function lighting graphics combination or a dynamic change of lighting mode, and the requirements for the functional safety of lamps and lanterns are also increasing. high. [0003] The dynamic turn signals on the market often use three input wiring harnesses, one positive and one negative two power supply lines and a dynamic steering effect enable signal line. This kind of solution needs to increase the output port of the on-board computer and the whole system at the same time when the v...

Problems solved by technology

[0003] The dynamic turn signals on the market often use three input wiring harnesses, one positive and one negative two power supply lines and one enabling signal line for dynamic steering effects. This solution needs to increase the output port of the trip computer and the whole system when the vehicle is updated. Car wiring harness, a large amount of modification involves a wide range of areas and increases costs
