摘要:
A software-defined powertrain transmits commands to at least 4 distributed polyphase motor controllers. A single vehicle control unit transforms operator control indicia into a plurality of individual commands, and securely transmits said commands to each one of a plurality of independent motor controllers mechanically coupled to a single wheel by a polyphase electric motor. The motor controllers are DC to variable AC electrical converters which each receives phase and magnitude requirements. A mixed criticality operating system provides an encrypted application-programming interface to operate functions such as torque vectoring, cooling, braking, and battery management. The OS provides an isolated trust zone to each of a plurality of cores for authentication and validation.

摘要:
A vehicle has independent electric traction system (ETS) and internal combustion engine (ICE). A system controller, a data acquisition system, and a GPS system are added to the vehicle. A remote system has a data base of locations identifying emission non-attainment areas. The data acquisition system obtains the vehicle location along with parametric data related to operation of the vehicle. The remote system notifies the vehicle operator and the auxiliary control system of opportunities to obtain emission reduction credits in response to the vehicle location data and its operating status. The system controller or the operator switch between ICE operation and ETS operation in response to the vehicle location, emission reduction credit process, and parametric measurements of the vehicle operation to achieve an emissions credit result while optimizing fuel for the ICE and stored electrical potential energy for the ETS.

A hybrid vehicle comprises an internal combustion engine, a traction motor, a starter motor, and a battery bank, all controlled by a microprocessor in accordance with the vehicle's instantaneous torque demands so that the engine is run only under conditions of high efficiency, typically only when the load is at least equal to 30% of the engine's maximum torque output. In some embodiments, a turbocharger may be provided, activated only when the load exceeds the engine's maximum torque output for an extended period; a two-speed transmission may further be provided, to further broaden the vehicle's load range. A hybrid brake system provides regenerative braking, with mechanical braking available in the event the battery bank is fully charged, in emergencies, or at rest; a control mechanism is provided to control the brake system to provide linear brake feel under varying circumstances.
