Speed adjusting method for racing car model

Abstract

Provided is a racing car model control system and a control method. The control system comprises a motor, a steering engine, a power supply, laser transmitting tubes, laser receiving tubes and a micro-controller. A racing car module is located on a white racing rack with two black edges, and in the running process, the micro-controller controls the laser transmitting tubes at different positions to emit laser signals and controls deflection of the steering engine and output of the motor according to the situation whether the laser receiving tubes corresponding to the laser emitting tubes for emitting laser receive laser diffuse reflecting signals. The racing car model control system judges the condition of the racing track in the front through the fed back diffuse reflecting signals to carry out speed adjustment and steering adjustment, detecting distance is prolonged, time preserved for adjustment of the micro-controller is correspondingly prolonged, load of the steering engine during steering is greatly reduced, running safety of the racing car model is improved, the racing car model is effectively prevented from rushing out of the track, meanwhile control flexibility and promptness are also improved, and running speed and safety stability of the racing car model are ensured.

Description

Technical field [0001] The invention relates to the field of racing or toy racing models, in particular to a method for adjusting the speed of a racing model. Background technique [0002] Smart racing models generally use smart tracking, which specifically refers to the car walking on a black line on a white floor, or if the frame is a black line, that is, walking on a white floor framed by a black line. Since the black line and white floor have different reflection coefficients to light, the "road" can be judged according to the intensity of the received reflected light. The usual method is infrared detection method. Infrared detection method, which uses infrared light to have different reflection properties on the surface of different color objects, and continuously emit infrared light to the ground during the driving process of the car. When the infrared light meets the white paper floor, it will be diffusely reflected, and the reflected light will be installed. The receive...
