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 and 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.

A structural member extends in a vehicle longitudinal direction. An off-center impact structure has a first member and a second member. The first member has a linear portion and an offset portion both having a hollow interior. The first linear portion extends through a first opening in the structural member in a direction perpendicular to the structural member and further extends in an outboard direction from the structural member. The offset portion is angularly offset from the first linear portion and extends laterally outboard and forward relative to the structural member. The second member has a first section and a second section. The first section is disposed within the hollow interior of the linear portion of the first member and the second section extends through of an opening in the first member outboard from the opening of the first member away from the hollow interior.

An automatic traveling vehicle includes a vehicle structure including a first top plate, and an electronic control unit. The electronic control unit is configured to execute a storage mode when a storage execution condition is satisfied. The storage mode includes a storage posture formation process of causing the vehicle to automatically travel so as to take a predetermined storage posture together with a counterpart automatic traveling vehicle. In the storage posture, the vehicle is in a superposition state in which the vehicle overlaps with the counterpart vehicle in a plan view, or a parallel state in which the vehicle is lined up with the counterpart vehicle while the first top plate and a second top plate of the counterpart vehicle are standing and facing each other so as to be parallel to or substantially parallel to a vertical direction.

A vehicle lower portion structure includes: a suspension member including a pair of left and right under from side members that extend in a vehicle front-rear direction, a cross member that extends in a vehicle transverse direction and connects the under front side members, and a steering gear box that extends in the vehicle transverse direction and is formed integrally with the cross member; and an under front bumper reinforcement that extends in the vehicle transverse direction and is installed between front end portions of the pair left and right under front side members.

A body on frame vehicle includes left and right front tubes and a lower support. The left front tube extends above a left front wheel well of the body on frame vehicle and terminates in a forward direction at a left forward end. The right front tube extends above a right front wheel well of the body on frame vehicle and terminates in the forward direction at a right forward end. The lower support includes a lateral portion, left riser portion, and right riser portion. A left end of the lower support extends upward from the lateral portion to form the left riser portion and a right end of the lower support extends upward from the lateral portion to form the right riser portion. The left and right riser portions are affixed to the left and right front tube proximate the left forward end and the right forward end, respectively.

The first member has a linear portion and an offset portion both having a hollow interior. The first linear portion extends through a first opening in the structural member in a direction perpendicular to the structural member and further extends in an outboard direction from the structural member. The offset portion is angularly offset from the first linear portion and extends laterally outboard and forward relative to the structural member. The second member has a first section and a second section. The first section is disposed within the hollow interior of the linear portion of the first member and the second section extends through of an opening in the first member outboard from the opening of the first member away from the hollow interior.

A chassis cab vehicle includes a lower frame, which constitutes a lower structure of the vehicle and is equipped with a pair of side members extending in a lengthwise direction of the vehicle. A battery is coupled between the side members. An upper body is coupled to a front portion of the lower frame and forms a cabin interior. A side sill is formed at a lower end at each side of the upper body and extends to a rear side of the cabin interior. The side sills overlap the respective side members in a lateral direction of the vehicle when coupled to the lower frame.
