Embodiment Construction

[0068] see figure 1 , The present invention provides an electric scooter control system, including a control part, a sensor part, a power supply part, a main circuit part, and a host computer part.

[0069] Control part: ST's STM32F103ZET6 is used as the main control chip. This chip has two advanced timers and a storage capacity of 512K. There are 5 kinds of IO ports and multiple serial communication interfaces, which meet the design requirements very well.

[0070] Sensor part: it is a gyroscope, which is used to collect the angle of body deviation.

[0071] Power supply part: charging module and battery; mainly used for battery charging and power supply of various parts of the system.

[0072] Main circuit part: power driver and two Hall brushless motors.

[0073] Host computer part: mobile phone and PC terminal.

[0074] The mobile phone mainly transmits information and transmits instructions through wireless Bluetooth; the PC terminal communicates through the serial por...

Abstract

The invention discloses a double-motor electric scooter control method and system. An operation state of an electric scooter is measured by using a gyroscope; and for different situations, moment reasonable distribution is realized, and accurate control is realized. During steering, a motor is allowed to realize electric scooter self-adaptive differential turning performance in the case of different loads so that the energy loss is reduced and the endurance of the system is improved; by using a measured value, in the corresponding direction, in gyroscope measured angles as Thetai1 and compensating a generated speed to a torque adjusting distributor, a compensated value of an angle value with greatest effect on the system is directly given to the torque adjusting distributor so that the adjusting effect of the system is accelerated. Compensated values of two angle values with smallest effects on the system are given to a PI adjuster with a given speed to slowly adjust the system. Afterreasonable distribution of the torque adjusting distributor, self-adaptive adjusting can be performed according to various road conditions.

Description

technical field [0001] The invention belongs to the technical field of electric scooter control, and in particular relates to a control method and system for a dual-motor electric scooter. Background technique [0002] Due to the rapid development of the country's economy, the number of private cars is increasing, which can easily lead to traffic paralysis; in addition, some relatively narrow places are not suitable for car traffic, and cars emit a lot of exhaust gas, polluting the air. So it is necessary to design a power control system device with small size, adjustable speed and environmental protection. The device can be fixed on any device with a relatively small volume (such as a traditional skateboard, bicycle, etc.), and the traditional means of transportation can be easily changed. Compared with traditional ones, the walking-replacing tool added with the control device is more labor-saving, faster and more convenient to carry. The introduction of this control syst...
