To reinforce a front sub-frame in such a manner that the front sub-frame having a trapezoidal shape formed by a cross member and left and right side members extending to one side is not deformed to a rhombus shape at the one side, a front sub-frame structure includes: a rear cross member (74) coupling arm supporting parts (71, 71) supported on left and right side members (6, 6); tilt members (75) coupling left and right intermediate portions of the rear cross member (74) to rear vehicle attachment parts (M3) of the side members (6); a brace (80) coupling the left and right arm supporting parts (71, 71) to the rear vehicle attachment parts (M3); and intermediate coupling parts (91) coupling the brace (80) to intermediate portions of the tilt members (75).

A first structure extends to a forward side of a cross-member of a vehicle frame with a first gap being defined between the first structure and the cross-member. A second structure extends rearward from the cross-member with a second gap defined between the second structure and the cross-member. An attachment bracket fixed to the cross-member retains one of the first and second structures. The attachment bracket is configured to maintain one of the first gap and the second gap in a non-impacted state. In response to an impact event where a stationary barrier impacts forward of the first structure, impacting forces cause movement of the one of the first structure and the second structure relative to the attachment bracket thereby bringing at least the one of the first structure and the second structure into contact with the cross-member closing the corresponding one of the first gap and the second gap.

A push arm is coupled to a vehicle frame proximate an intersection of a first side member and a first cross-member. A rear surface of the push arm is located adjacent to a front suspension structure with a gap defined therebetween. The push arm extends forward and laterally outward such that a front surface of the push arm is located outboard of and spaced apart from a front end of the first side member. An energy absorbing structure is positioned within the gap and is attached to the rear surface of the push arm. The energy absorbing structure is spaced apart from the front suspension structure in a non-impacted state. The energy absorbing structure is configured such that in response to an off-center impact event, impact force to the energy absorbing structure pushes the energy absorbing structure into contact with the front suspension structure, such that the energy absorbing structure deforms and absorbs impact energy.

An off-center impact reinforcement structure includes a push arm proximate rearward of a front portion of the vehicle frame. The push arm extends in a forward and laterally outboard direction from a front side member. A rear surface of the push arm is located below the first side member. During an initial stage of an off-center impact event in which a stationary barrier directly impacts a front surface of the push arm, impacting forces from the off-center impact event move the rear surface of the push arm into contact with brackets that extend downward from the front side member and transfer through the push arm to brackets and to the vehicle frame. In a second stage, a rear surface of the push arm contacts the vehicle frame as the push arm pivots with the front surface of the push arm moving in a laterally outboard direction.

A vehicle structure includes a vehicle frame, a beam, an attachment bracket. The vehicle frame has a first side member, a second side member and a cross-member rigidly fixed to each of the first and second side members and extending between the first and second side members. The beam extends rearward from a mid-portion of the cross-member with a gap being defined between the beam and the cross-member. The attachment bracket is rigidly fixed to the mid-portion of the cross-member and retaining the beam. The attachment bracket is configured to maintain the gap with the vehicle frame in a non-impacted state. The attachment bracket is further configured such that in response an impact event impacting a forward area of the vehicle frame, with impacting forces causing relative movement between the cross-member and the attachment bracket, the gap is diminished or closed.

Occupants of an autonomous vehicle may not always have a view of the outside environment (e.g., they may be occupied consuming digital content, or their vehicle may not have windows). However, such occupants may benefit from gaining a view to the outside environment when an unexpected driving event is about to occur. Such a view can increase their awareness to the event, making them less likely to be surprised, disturbed, or distressed by the event. In one embodiment, an occupant of an autonomous vehicle receives a video see-through (VST) of the environment outside the vehicle when such an unexpected driving event is imminent.

A Shock-Absorbing Energy Dissipation Padding (SAEDP) is coupled to the compartment of an autonomous on-road vehicle, and is located, during normal driving, at eye level in front of an occupant who sits in a front seat of the vehicle. The vehicle further includes a stiff element that supports the SAEDP and resists deformation during collision in order to reduce compartment intrusion. The stiff element is located, during normal driving, at eye level between the SAEDP and the outside environment. Optionally, a camera takes video of the outside environment in front of the occupant, and a computer generates for the occupant a representation of the outside environment.
