Bumper bean design for crash signal separation

A system for airbag deployment within a vehicle, comprising:

• an airbag;
• a bumper beam including a left crush can and a right crush can which 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,
• wherein the first zone and the second zone are arranged laterally in a vehicle widthwise direction;
• at least one sensor receiving one or more signals associated with an impact on the vehicle;
• and
• an electronic control unit (ECU) deploying the airbag based on an amplitude or a wavelength of one or more of the signals compared to an amplitude threshold or a wavelength threshold associated with the first stiffness of the first zone and the second stiffness of the second zone.

• a bumper beam including a left crush can and a right crush can which 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 and arranged inboard of the first zone,
• wherein the first zone and the second zone are arranged laterally in a vehicle widthwise direction,
• wherein the second stiffness of the second zone is greater than the first stiffness of the first zone;
• an accelerometer receiving one or more signals associated with an impact on the vehicle;
• and
• an electronic control unit (ECU) deploying the airbag based on an amplitude or a wavelength of one or more of the signals compared to an amplitude threshold or a wavelength threshold associated with the first stiffness of the first zone and the second stiffness of the second zone.
