An automotive vehicle may include an electric machine and a controller. The electric machine may be configured to provide and receive mechanical torque. The controller may be configured to determine forward or backward movement of the vehicle based on the provided or received mechanical torque and a mechanical power of the electric machine.

摘要:
A system for validating velocities of components in a vehicle uses sensor measurements and mathematical relationships between the vehicle components to validate the velocities. A controller or controllers receive speed or velocity inputs and mathematically combine the velocities of more than one of the vehicle components. The velocities of at least one of the vehicle components is validated when the mathematical combination meets at least one predetermined criterion. The validated velocity or velocities are then communicated to at least one of the vehicle components.

摘要:
A method for validating engine and motor velocities in a vehicle having an engine and two motors is provided. The method validates the velocities without using two speed sensors for each device. The velocities of the engine and the two motors are first determined, and then mathematically combined using known velocity relationships based on the vehicle architecture. The mathematical combination of the velocities is then compared to a first pre-determined speed range, and if the mathematical combination is within the predetermined range, the velocities of the engine and the two motors are validated. If the validation of the engine and the two motors fails, additional equations can be used utilizing additional inputs, including the vehicle speed as measured at the vehicle wheels. In this way, the velocities of one or more of the torque generating devices in the vehicle may be validated.
