METHOD AND SYSTEM FOR CONTROLLING ACTUATABLE PROTECTION DEVICE WITH ENHANCED ROLLOVER DISCRIMINATION

A method for controlling the actuation of an actuatable restraint to help protect a vehicle occupant in response to a rollover event is implemented in a controller of a vehicle safety system that includes the actuatable restraint. To implement the method, the controller is configured to execute a roll discrimination metric that discriminates the occurrence of a ramp rollover event or an embankment rollover event in response to a vehicle roll rate (R_RATE) having a magnitude that exceeds a predetermined threshold roll rate (R_RATE). The controller is also configured to execute a switching metric that is operative to reduce the predetermined threshold roll rate (R_RATE) in response to a vehicle pitch rate (P_RATE) having a magnitude that exceeds a predetermined threshold pitch rate (P_RATE). The invention also relates to a vehicle safety system. 本发明涉及一种用于响应于侧翻事件而控制可致动约束装置的致动以帮助保护车辆乘员的方法，该方法在包括该可致动约束装置的车辆安全系统的控制器中实施。为了实施该方法，该控制器被配置成执行侧倾判别度量，该侧倾判别度量响应于车辆侧倾速率(R_RATE)的大小超过预定阈值侧倾速率(R_RATE)而判别发生坡道侧翻事件还是路堤侧翻事件。该控制器还被配
