A bumper beam design for crash signal separation. A system for airbag deployment within a vehicle may include an airbag, a bumper beam, at least one sensor, and an electronic control unit (ECU). The bumper beam may include a left crush can and a right crush can. The left crush can and the right crush can may each include a first zone associated with a first stiffness in a vehicle longitudinal direction and a second zone associated with a second stiffness in the vehicle longitudinal direction. The sensor may receive one or more signals associated with an impact on the vehicle. The ECU may deploy the airbag at a timing based on one or more characteristics of one or more of the signals and one or more predetermined characteristics associated with the first stiffness of the first zone and thesecond stiffness of the second zone, thereby providing robust discrimination between a front flat impact mode and an front offset impact mode. 用于碰撞信号分离的保险杠横梁设计。种用于安全气囊在车辆内展开的系统可以包括安全气囊、保险杠横梁、至少个传感器以及电子控制单元(ECU)。保险杠横梁可以包括左挤压罐和
