Abstract: Aspects assure the performance of a hoist system. Some aspects model different shape segments to different portions of braking pressure levels acquired over time during an emergency braking event. A linear shape is modeled to braking pressure values decreasing over a first time interval from initiation of the emergency braking event. A constant shape is modeled to generally constant acquired braking pressure values of a next, second time interval, another linear shape modeled to braking pressure values decreasing over a next, third time interval, and another constant shape is modeled to the braking pressure values acquired over a fourth interval from a time at which the speed value drops to zero, until an exponential shape is modeled to braking pressure values of a subsequent fifth interval. A pressure value defined by the constant shape modeled over the fourth interval determines a permissible braking pressure value for the emergency braking event.
