A distributed torque monitoring and control system for a hybrid vehicle.
The hybrid vehicle has a power transfer unit adapted to drive a vehicle
wheel and a power source adapted to drive the power transfer unit. The
system includes a local torque monitor and a vehicle level torque
monitor. The local torque monitor is associated with the power source and
is adapted to implement a local mitigation strategy to inhibit undesired
torque. The vehicle level torque monitor is adapted to implement a
vehicle level mitigation strategy to inhibit acceleration of the hybrid
vehicle if the local mitigation strategy is unsuccessful.
