Example Embodiment

[0010] As shown in the figure, the present invention includes a controller, a motor, a comparator, a fan, a steering gear, an airflow sensor, a speed sensor, a voltage stabilizing circuit, an LED, a memory, and a power supply. The input port of the controller is connected; the output port of the controller is connected with the steering gear, the motor, and the LED; the controller is also connected with the power supply and the fan.
[0011] The controller of the present invention is an XS128 chip.
[0012] The intelligent vehicle positioning system of the present invention uses a laser tube and a receiving chip to detect the track in front of the vehicle, and obtains track data by sampling the analog signal of the phototransistor through MC9S12XS128, and combines certain algorithms to extract the black and white lines of the track to drive the steering gear and the motor Chip with proper control.
[0013] The steering of the steering gear is a link with greater delay in the entire control system. Under the same steering gear conditions, the farther the connection point of the steering link at one end of the steering gear is from the axis of the steering gear, the faster the steering wheel steering changes. The advantages of this installation are: the moment arm of the steering gear is changed to make the steering more sensitive; the steering gear is installed in the center to make the left and right steering basically the same; the center of gravity is relatively rearward, reducing the load of the steering gear.
[0014] Adjustment of the rear wheelbase: When the car is running at high speed, it is easy to overturn when turning suddenly. In order to increase the balance ability of the whole car, the original rear wheel adjustment part of the car model can be changed to a large wheelbase adjustment part, so that the rear wheelbase is in the original Based on the increase of 4mm, the sideslip is further reduced.
[0015] The adjustment of front wheel parameters includes front wheel kingpin caster angle, kingpin inclination angle, front wheel camber angle, and front wheel toe. These parameters have a very important influence on the stability of the car body in a straight line and the flexibility of turning.
[0016] Fix the laser tube in the lower row of holes and the upper row of six fixed receiving tubes and lenses, and adjust the laser irradiation distance to 50CM, and the forward-looking effect is the best.
[0017] The lower the center of gravity, the better. When choosing a camera, choose a lighter one, the material and specifications of the camera bracket should also be considered, and the placement of the circuit board should be as low as possible.
[0018] It is understandable that the above specific description of the present invention is only used to illustrate the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those of ordinary skill in the art should understand that the present invention can still be modified or modified. Equivalent replacement to achieve the same technical effect; as long as the use needs are met, it is within the protection scope of the present invention.
