Title:
SYSTEM AND METHOD FOR EMERGENCY BRAKE CONTROL
Document Type and Number:
WIPO Patent Application WO/2020/163418
Kind Code:
A3
Abstract:
Disclosed are systems and methods for regulating application of an emergency brake configured to minimize jerk for riders' comfort while assuring safe application of the emergency brake. An emergency brake optimization module may be provided and positioned in fluid communication with a standard hydraulic brake system to regulate the application of the emergency brake through (i) providing an initial inflow of hydraulic fluid through a dead time caliper fill circuit to the brake supply line during a dead time period of fluid supply through the emergency brake valve to reduce dead time in emergency brake application, (ii) providing an oversized choke, or optionally no choke, in the emergency brake circuit with jerk being controlled through consumption of excess hydraulic fluid by a secondary volume consumption circuit, and (iii) providing both a dead time caliper fill circuit and a secondary volume consumption circuit to more precisely control reduction in dead time and minimization of jerk during application of the emergency brake.
