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.
