Abstract: A drive system for a vehicle having a maximum speed, the drive system comprising: a first electric drive motor configured to drive both a first wheel and a second wheel of the vehicle; a differential coupled to the first electric drive motor, the differential being configured to split drive provided by the first electric drive motor so as to form a first drive path from the differential to the first wheel and a second drive path from the differential to the second wheel; a second electric drive motor positioned along the first drive path and configured to drive the first wheel; and a third electric drive motor positioned along the second drive path and configured to drive the second wheel; wherein each of the first, second and third electric drive motors are configured to provide drive up to the maximum speed of the vehicle.

Abstract: A vehicle comprising: first and second front electric motors, each front electric motor being coupled to a respective front wheel to drive that front wheel; a rear electric motor; an internal combustion engine, the internal combustion engine and rear electric motor being coupled to a rear axle to drive rear wheels; and three motor control units each comprising drive components, each motor control unit being coupled to a respective electric motor to drive that electric motor using the drive components, and the front and rear electric motors having a common set of physical characteristics so that each of the motor control units has identical drive components.

Abstract: Abstract of the Disclosure A computer system, computer-readable medium and a method for performing activity based cost modeling. A cost object array has dimensions defined by weight arrays each corresponding to facets of the business by which one would assess profitability and efficiency, such as by products and customers. Each element of the weight arrays represents a user-definable classification, such as particular product families or geographic regions, and is assigned an allocation weight. A cost driver array has the same dimensions as the cost object array comprising metrics, such as the quantity sold or dollars of revenue. A weighted allocation factor for each cost object is a normalized function based on the allocation weights for the corresponding elements of each weight array and the cost driver array with in the cost object array.  Activity costs are allocated to a particular cost object in proportion to the weighted allocation factor associated with that cost object.
