Vehicle corner module and methods for installation thereof
Some embodiments relate to a vehicle corner module (VCM) connectable to a VCM-connection interface of a reference-frame of a vehicle platform (e.g. for regulating motion of a vehicle). Some embodiments relate to a multi-interface connection-element for connection of multiple electronic or flow vehicle subsystems of a vehicle to a Vehicle Corner Module (VCM). Related methods are disclosed herein.

a vehicle-connection interface for reversible mechanical connection of the VCM to the VCM-connection interface of the reference frame;
a wheel-hub assembly comprising a wheel-hub adapted for mounting of a wheel thereon; and
at least one subsystem of the vehicle, comprising a subsystem unit mounted onto the base of the sub-frame, the at least one subsystem being selected from the group of subsystems consisting of a drive subsystem, a steering subsystem, and a braking subsystem,
