An adaptive control method for intermediate shaft brake
By using an adaptive control method, abnormal resistance in the transmission chain of the intermediate shaft brake is identified and overcome. The inflation time is extended and a cycle verification mechanism is set up, which solves the problem of shifting failure in the intermediate shaft brake control under abnormal working conditions, and achieves the effects of smooth shifting and reduced maintenance costs.

AI Technical Summary
Existing intermediate shaft braking control cannot quickly reduce speed when faced with abnormal mechanical resistance in the transmission chain, resulting in gear shift failure. Furthermore, it relies on manual adjustment of braking parameters, leading to high maintenance costs, and conventional control strategies are prone to falling into ineffective control loops.
By using an adaptive control method, the duration of the opening request and the threshold for secondary air replenishment are obtained, the deceleration obstruction state is identified, the inflation time is extended and the brake air pressure is increased, and a brake opening count verification mechanism is set to prevent repeated inching and ensure synchronous engagement of the transmission.
It enables automatic adjustment of inflation parameters under abnormal operating conditions, avoids ineffective control cycles, reduces maintenance costs, and ensures smooth execution of the shifting process.
