when the scooter runs straight at a constant speed, a pressure difference threshold value at two ends of the pedal (1) is set through the processor (4-1), a driver stands upright, the difference value of the acting force of front and rear feet is kept within the pressure difference threshold value range, the front and rear of the pedal (1) are horizontal, the pose of the scooter is collected and measured through the precision gyroscope (4-3), the processor (4-1) controls the motor driver (4-4) to drive the double-shaft motor (12) to be fixed in rotating speed, and the scooter runs straight at a constant speed;
when the scooter turns left or turns right, the driver decelerates ahead of the turning position in advance, the driver pushes the rear foot to the right front or the left front at the turning position to finish turning action, and meanwhile, the gravity center of the body is adjusted, the pedal (1) is balanced, and the scooter is controlled to stably run;
step 202, judging whether the road is flat: manually identifying the road flatness by a driver, and circulating the step 201 when the road is flat; when the road is uneven, step 203 is executed;
step 203, judge the height of the uneven obstacle
Whether the driving state of the driver is established and adjusted: the scooter runs on uneven road, and when the height L of the uneven obstacle meets the following conditions:
when the driver does not walk, the driver can stably buffer up and down through the damping mechanism of the scooter and the step 201 is circulated; when the height L of the uneven and uneven obstacle on the road meets the following conditions:
when the vehicle is in use, the wheels (5) are blocked by an obstacle, a driver stands on the pedal (1) to press the spring (15) in the buffer block (7), the spring (15) gives a counterforce to the driver standing on the pedal (1) in the process of restoring deformation, and the driver and the scooter jump over the obstacle at the same time, and then the step 201 is circulated, wherein R is the radius of the wheels (5); otherwise, executing the third step;
step three, the driver jumps down the scooter to assist the scooter to pass through the obstacle and then circulates the step two;
step four, finishing driving: the driver jumps down the scooter and turns off the power switch (4-5).
2. Use according to claim 1, characterized in that: when the uneven obstacle height L satisfies in step 203:
when drivingA person stands on the pedal (1) to extrude the spring (15) in the buffer block (7), and the closed space enclosed by the pedal (1), the sliding block (13), the sealing telescopic piece (16) and the sealing observation window (9) extrudes air to enable the air in the closed space to flow out from the air holes (8), so that the air resistance is instantly generated to generate downward stable buffer for the driver; the extruded spring (15) gives a counterforce to a driver standing on the pedal (1) in the process of recovering deformation, and the closed space surrounded by the pedal (1), the sliding block (13), the sealing telescopic piece (16) and the sealing observation window (9) sucks air, so that the air in the closed space flows in from the air holes (8), and the air resistance is generated instantly to generate upward stable buffering for the driver.
