Problems solved by technology

[0004] It can be seen that when the speed V reaches a certain value and r is less than a certain value, the F value will reach or even exceed the critical value that causes the car body to overturn, resulting in the car body toppling or even a rollover accident
Therefore, the differential speed control method described in the invention patent No. CN 105490594 A and the patent name "double brushless low-voltage DC motor drive control system and method" is a major safety hazard.

Abstract

The invention relates to the field of intelligent speed control, in particular to a vehicle body overturning prevention control system and method by electronic differential of dual direct current motor driver. The problem of steering safety of a vehicle body under the driving of a two-motor direct current mode is solved. According to the steering process of the vehicle body, the load characteristics of a two-way motor are controlled in real time to be quantified, the collected data is used for analyzing whether the vehicle body has the danger of overturning or not according to the quantized data by a formula; when the vehicle body is about to overturn, the speeds of Speed<1> and Speed<2> of the vehicle body are reduced by f([delta]X), the parameters calculated by [delta]X are added; and inthe differential process, the vehicle body stabilization of the vehicle body can be optimized according to the changes of data parameters. The stability of the vehicle body operation in a two-motor direct current driver using the algorithm can be improved, and the risk of overturning of the vehicle body can be reduced. The vehicle body overturning prevention control system and method ensure the maximum advance speed while ensuring anti-overturning during cornering, so that the vehicle body is safer, more flexible and more efficient. The vehicle body overturning prevention control system and method are mainly applied to the intelligent control over the vehicle body speed.

Description

technical field [0001] The invention relates to the field of speed intelligent control, and more specifically, relates to a control system and method for electronic differential speed prevention of dual DC motor drivers to prevent vehicle body from overturning. Background technique [0002] During the operation of the car body, how to ensure that the car body does not overturn when turning has become an important safety indicator for dual-machine DC drive; especially when the center of the car body changes, it is very important to use a fixed parameter setting method. It is difficult to strike a balance between forward speed and fast turning; especially after some wheeled vehicles and tracked vehicle platforms are installed with tops, the running road conditions are complex, and it is more likely to cause overturning accidents; especially in explosion-proof, fire-fighting, and hazard detection In other applications, human remote control is used to control the car body, which...
