    摘要: A control arm includes a wheel side end, a body side end, a first connecting member extending between the wheel side end and the body side end, a second connecting member extending between the wheel side end and the body side end, and having a reduced section portion, and a fracture zone extending through the first and second connecting members in a substantially fore-aft direction of the vehicle, the reduced section portion being within the fracture zone. A thickness of the reduced section portion is tunable to establish a controlled fracturing during a small overlap rigid barrier impact event where: (i) an initial fracture of the first connecting member occurs within the fracture zone, and (ii) a secondary fracture of the second connecting member occurs within the fracture zone at the reduced section portion, to thereby provide a desired rearward trajectory of the wheel assembly during the impact event.
