Vehicle corner modules (VCMs) connectable to a VCM-connection interface of a reference-frame of a vehicle platform, for regulating motion of a vehicle. When a wheel is mounted on a wheel-hub assembly of the VCM, a vehicle-connection interface of the VCM is disposed within a cylindrical footprint of the wheel. At least one of the at least one subsystem of the VCM is accommodated between the wheel-hub assembly and the vehicle-connection interface. Vehicle platforms are connectable to the VCMs. The connection of the vehicle platform to the VCM may include connection of subsystems of the VCM to electronic or flow subsystems mounted on the vehicle platform by connection of two portions of a multi-interface connection-element.

Vehicle corner modules and systems and methods for installation thereof

Generally, a suspension system for a wheel of a vehicle is disclosed. The system may include at least one pair of arms each including a first arm and a second arm. Each of the first arm and the second arm of the at least one pair of arms may have a first end adapted to be rotatably connected to a wheel interface and a second end adapted to be rotatably connected to a reference frame of the vehicle, while the first arm and the second arm may be set across each other and define a mobile steering axis at a virtual intersection therebetween such that the mobile steering axis moves with respect to the reference frame when the wheel interface changes its steering angle relative to the reference frame.
