Title:
ELECTRICAL VEHICLE AND METHOD OF PROVIDING MOTIVE TORQUE IN ELECTRIC VEHICLE USING AT LEAST TWO ELECTRICAL MOTORS
Document Type and Number:
WIPO Patent Application WO/2019/053270
Kind Code:
A3
Abstract:
Disclosed is an electrical vehicle and a method of providing motive torque in an electrical vehicle. The electrical vehicle includes a vehicle frame arrangement, at least one front wheel and a pair of rear wheels rotatably coupled onto the vehicle frame arrangement, and an electrical motor arrangement for applying in operation torque to at least the pair of rear wheels to propel the electrical vehicle in a forward or a reverse direction, characterized in that (i) the electrical motor arrangement includes at least two electrical motors for applying in operation torque to the at least the pair of rear wheels; (ii) the at least two electrical motors are mutually independently controllable from a motor control arrangement of the electrical vehicle; and (iii) the at least two electrical motors are implemented as a sprung element of the vehicle frame arrangement and are coupled via a coupling arrangement to their corresponding wheels, or an electrical vehicle and a method of providing motive torque in an electrical vehicle. The electric vehicle including a vehicle frame arrangement, at least three wheels coupled onto the vehicle frame arrangement, and an electrical motor arrangement for applying torque to the at least three wheels to propel the electric vehicle in a forward or a reverse direction, characterized in that: the electrical motor arrangement includes at least three electrical motors for applying torque to the at least three wheels; the at least three electrical motors are mutually independently controllable from a motor control arrangement of the electric vehicle; at least one of the at least three electrical motors is implemented as an in-hub electrical motor; and at least one of the at least three electrical motors is implemented as a sprung element of the vehicle frame arrangement and is coupled via a coupling arrangement to corresponding wheel.
