Abstract

The invention discloses a vehicle electronic whistling horn control circuit having temperature compensation and a compensation method. A common vehicle whistling horn does not adopt the temperature compensation, so when a horn temperature and an environment temperature change, the vehicle horn cannot obtain better environment adaptability. The vehicle electronic whistling horn control circuit having the temperature compensation comprises a controller (1), a driving circuit (2), a horn system (3) and a temperature compensation circuit (4); the controller is connected with the driving circuit; the driving circuit is connected with the horn system; the controller and the temperature compensator are formed into a temperature compensation system; the controller sends corresponding pulses to pass through the driving circuit; and the driving circuit drives the horn system. The vehicle electronic whistling horn control circuit having the temperature compensation and the compensation method disclosed by the invention are applied to the vehicle whistling horn.

Description

[0001] Technical field: [0002] The invention relates to a vehicle electronic whistle horn control circuit with temperature compensation and a compensation method. [0003] Background technique: [0004] Ordinary car horns do not use temperature compensation. When the temperature of the horn and the ambient temperature change, the car horn cannot obtain better environmental adaptability. [0005] Invention content: [0006] The object of the present invention is to provide an electronic whistle horn control circuit with temperature compensation for vehicles, which has simple manufacturing process, low cost, good sound effect and convenient production. [0007] Above-mentioned purpose realizes by following technical scheme: [0008] An electronic whistle horn control circuit with temperature compensation for a vehicle, its composition includes: a controller, a drive circuit, a horn system and a temperature compensation circuit, the controller is connected with the drive circu...
