Embodiment Construction

[0026] The embodiment of the present invention will be explained in detail below in conjunction with the accompanying drawings. The examples given are only for the purpose of illustration, and cannot be interpreted as limiting the present invention. The accompanying drawings are only for reference and description, and do not constitute the scope of patent protection of the present invention. limitations, since many changes may be made in the invention without departing from the spirit and scope of the invention.

[0027] Such as figure 1 As shown, the existing automatic transmission vehicles are all provided with a gear indicator light controlled by a gear indicator controller, and the gear indicator controller is provided with a corresponding figure 1 The "P R N D S L" shown in the indicator light of these gears, but most of the gear indicator lights can not adjust the intensity of the backlight in real time according to the ambient light intensity signal.

Abstract

The invention relates to the technical field of brightness regulation of gear indicator lights for automatic transmission vehicles, and specifically discloses an automatic brightness control circuit of gear indicator lights interacting with a vehicle controller. The automatic brightness control circuit is provided with a gear indicator controller and an LED driving circuit connected therewith, anLED light emitting circuit connected with the LED driving circuit, a working power supply connected with the gear indicator controller and the LED light emitting circuit, a vehicle controller connected with the gear indicator controller and the working power supply, and a sunlight sensor connected with the vehicle controller and the working power supply. The beneficial effect of the invention is as follows: the external sunlight sensor collects the real-time ambient light intensity signal in a vehicle and outputs a voltage corresponding to the ambient light intensity signal to the vehicle controller, and the vehicle controller sends the voltage to the gear indicator controller and outputs different PWM signals to the gear indicator lights, so as to make the brightness of the gear indicatorlights increase with the increase of ambient light intensity and decrease with the decrease of ambient light intensity in real time.

Description

technical field [0001] The invention relates to the technical field of brightness adjustment of a gear position indicator light of an automatic transmission vehicle, in particular to an automatic control circuit for the brightness of a gear position indicator light interacting with a vehicle-mounted controller. Background technique [0002] At present, more and more cars use automatic transmission cars, and each gear has a corresponding indicator light (such as figure 1 The P R N D S L letters shown have corresponding indicator lights), which makes the car operation more convenient and driving safety, but it brings some problems. At present, most gear indicator lights cannot adjust the intensity of the backlight in real time according to the ambient light intensity signal. Weak, it can only be adjusted according to the light line signal, that is, one brightness during the day and one brightness when driving at night, which often causes the user to see the gear indicator too ...
