Embodiment 1

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

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

[0055] A2. Carry out speed detection and judgment on vehicles;

[0056] A3. If the car is flying, the power supply of the vehicle will be turned off directly, and a speeding fault alarm will be issued;

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

[0058] A5. If the throttle is valid, the vehicle will be driven to run, and the vehicle will be started to enter the driving state;

[0059] A6. If the throttle is invalid, then return to step A4 above;

[0060] A7. Judging whether the driving speed of the vehicle is greater than the set speed, and performing t...

Embodiment 2

[0081] image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 In the shown embodiment, a turning deceleration module for a slow vehicle smooth turning control method includes a brushless motor 40 and a motor drive circuit 30, and also includes a gyroscope for collecting signals from the gyroscope 61 described in Embodiment 1 The instrument chip sensor and the Hall element 50 used for Hall feedback speed to the brushless motor speed signal, the gyroscope 61 chip sensor, the Hall element 50 and the motor drive circuit 30 are electrically connected to the MCU processor 20 chip respectively, and the slow speed The speed of the vehicle is set to 70 through the accelerator, and the speed signal is transmitted and connected to the MCU processor chip; when the vehicle is turning, the signal mutation data collected by the gyroscope chip sensor 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 slow vehicle stable turning control method and a turning deceleration module used for the method; after a vehicle is powered on, initialization operation is carried out on the modules, after initialization, whether galloping occurs or not is detected, and if galloping occurs, the vehicle is directly shut down. And if no galloping exists, whether an accelerator signal is valid or not is detected, if so, the vehicle is driven to run, whether the vehicle speed exceeds 2 km / h or not is judged, if so, the turning detection function is started, and if not, the function is not started. When the running speed of the vehicle exceeds 2 km / h, the minimum turning threshold value is judged through turning, if the turning strength exceeds the minimum turning threshold value, turning deceleration control is started to control the target speed after turning is completed, the higher the turning strength is, the lower the target speed is, and the phenomenon of turnover can be effectively avoided. The turning safety of the low-speed vehicle is improved, the driving safety and reliability of the elderly are improved, accidents are prevented, and the travel safety of the elderly is guaranteed.

Description

technical field [0001] The present invention relates to an old generation scooter, in particular to a slow vehicle smooth turning control method used in the old generation scooter to implement a balance control scheme for vehicle turning. Background technique [0002] With the intensification of population aging, the proportion of the elderly population continues to increase. The "2018 China Senior Care Industry Market Research Report" pointed out that China has entered the early stage of an aging society, and the aging population in China is growing rapidly and on a large scale. 15.5%, a net increase of 110 million elderly population. It is estimated that by 2025, the elderly population over 60 years old in my country will reach 487 million people. The satisfaction rate of China's elderly care 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 Ch...
