A recently granted patent (Publication Number: US11964591B2) discloses a braking method for vehicles that involves obtaining various state information of the vehicle, such as mass and deceleration required for braking. The method includes calculating the braking torque needed and controlling the output of an electric braking torque accordingly. Additionally, the method involves determining the maximum electric braking exit speed based on factors like allowable gradient, vehicle mass, and deceleration required for braking. The vehicle is then controlled to unload the electric braking torque when the current speed is below the maximum exit speed.

Furthermore, the patent details a braking device for vehicles that includes modules for obtaining state information, calculating braking torque, and controlling electric braking torque output. The device also considers factors like current vehicle speed and maximum electric braking exit speed to efficiently manage the braking process. The patent also covers the integration of this braking device into vehicles, ensuring optimal braking performance based on the calculated parameters. Overall, the patented braking method and device aim to enhance vehicle safety and efficiency by precisely controlling braking operations based on real-time data and predetermined thresholds.
