The invention discloses an automobile speed limiting system based on a single chip computer. The automobile speed limiting system comprises a speedometer, a Hall sensor, a key operation part, an indicator light, the single chip computer, a display, a relay, an alertor, a throttle valve motor, a throttle valve opening part, a fuel injection quantity part and an automobile speed part. The speedometer is connected with the Hall sensor. The single chip computer is connected with the Hall sensor, the key operation part, the indicator light, the display, the relay and the alertor. The relay is connected with the throttle valve motor. The throttle valve motor is connected with the throttle valve opening part. The throttle valve opening part is connected with the fuel injection quantity part, and the fuel injection quantity part is connected with the automobile speed part. According to the automobile speed limiting system based on the single chip computer, by adopting the single chip computer technology, the precision of the system and the stability of working are effectively improved; the current speed information of the automobile can be displayed timely and accurately; meanwhile, unnecessary manual operation is reduced as far as possible; alarming can be carried out anytime and anywhere; and meanwhile, the automatic speed reduction of the automobile after overspeed can be achieved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile speed-limiting system based on a single-chip microcomputer. Background technique [0002] With the rapid development of my country's automobile industry, more and more Chinese ordinary people have the financial strength to buy cars. However, things always have its two sides. There are more cars, and the resulting road traffic safety problems have become increasingly prominent. According to statistics, speeding is the most prominent among national traffic accidents, and 35.3% of traffic accidents are caused by speeding. Therefore it is necessary to take measures to enforce the speed limit to maintain the safety of individuals and pedestrians. [0003] The present invention, to a large extent, effectively solves the difficult problem of overspeed driving, effectively prevents drivers from overspeeding intentionally or unintentionally, and at the same time reduce...
