Abstract

The invention discloses an automobile speed limit reminding method. The invention is structurally characterized by comprising a vehicle speed sensor (1), a single chip microprocessor (2), a speech alarm (3), a horn (4), a digital display module (5) and a keyswitch (6); a driver sets an alarm vehicle speed by utilizing the keyswitch (6); the digital display module (5) displays the set alarm vehicle speed; the sensor (1) extracts a vehicle speed signal of an automobile; after the signal is conditioned, operated and compared by the single chip microprocessor (2), the result is transmitted to the speech alarm (3); and the speech alarm (3) gives out a signal through the horn (4). After the automobile is started, the automobile runs on a speed limit road section, the driver sets the speed limit, the vehicle speed sensor transmits the vehicle speed signal to the single chip microprocessor in time, the single chip microprocessor carries out conditioning and operation on the vehicle speed signal and compares the signal with the stored set standard to draw a conclusion, and the speech alarm gives out the signal to remind the driver.
