Embodiment 1

[0053] figure 1 , figure 2 , Figure 4 , Figure 5 In the illustrated embodiment, a method for controlling a smooth turning of a slow-speed vehicle includes the following steps of turning and decelerating control (each step corresponds to a number shown in the figure)

[0054] A1. After the vehicle 70 is powered on, first initialize the entire turning deceleration module;

[0055] A2. Perform flying car detection and judgment on the vehicle;

[0056] A3. If the car is flying, then directly turn off the power of the vehicle and issue an alarm for the speed of the car;

[0057] A4. If there is no flying car, the side execution judges the effective state of the accelerator;

[0058] A5. If the accelerator is valid, execute the driving vehicle operation, and start the vehicle to enter the driving state;

[0059] A6. If the accelerator is invalid, then execute the return and enter the above step A4;

[0060] A7. Determine whether the vehicle speed is greater than the set sp...

Embodiment 2

[0082] image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 In the illustrated embodiment, a turning deceleration module for a slow-speed vehicle smooth turning control method includes a brushless motor 40 and a motor drive circuit 30, and also includes a gyroscope for collecting the signals of the gyroscope 61 described in Embodiment 1. A sensor chip sensor and a Hall element 50 for performing Hall feedback speed on the brushless motor speed signal, a gyroscope 61 chip sensor, a Hall element 50 and a motor drive circuit 30 are respectively electrically connected to the MCU processor 20 chip, and the slow speed The speed of the vehicle is given 70 through the accelerator, and the speed signal transmission is connected to the MCU processor chip; when the gyroscope chip sensor is turning the vehicle, the signal mutation data collected is transmitted and fed back to the MCU processor chip, and the MCU processor chip is based on The magnitude of th...

Abstract

The invention discloses a smooth turning control method of a slow vehicle and a turning deceleration module used in the method. After the vehicle is powered on, the module is initialized first. After the initialization, whether the vehicle is flying or not is detected, and the flying car directly shuts down the vehicle. If there is no flying car, check whether the accelerator signal is valid, if it is valid, drive the vehicle to run, determine whether the vehicle speed exceeds 2km / h, if it exceeds the set value, start the turning detection function, if the speed is less than 2km / h, then do not start the function Function. When the driving speed of the vehicle exceeds 2km / h, the turning judgment minimum turning threshold is performed. If the turning intensity exceeds the minimum turning threshold, the turning deceleration control will enter the target speed after turning. When the turning intensity is stronger, the target speed is smaller, which can be effective Avoid rollovers. Increase the safety of slow vehicles when turning, improve the safety and reliability of the elderly, prevent accidents, and ensure the safety of the elderly.

Description

technical field [0001] The invention relates to an old-age scooter, in particular to a slow-speed vehicle smooth turning control method used in the old-age scooter to implement a balance control scheme for vehicle turning. Background technique [0002] As the population ages, the proportion of the elderly population continues to increase. The "2018 China Elderly Care Industry Market Research Report" pointed out that China has entered the early stage of an aging society, and China's aging population is growing rapidly and in large scale. 15.5%, with a net increase of 110 million elderly population. It is estimated that by 2025, my country's elderly population over the age of 60 will reach 487 million. The satisfaction rate of China's elderly service demand is only 16%, and nearly 84% of the elderly's needs have not been met. At present, the development scale of elderly rehabilitation and home health care equipment in China is one tenth of that in Europe and the United State...
