Abstract
A torque based monitor method, apparatus, and system, for a torque splitting hybrid electric vehicle (HEV) powertrain and regenerative brake 54 system. The preferred powertrain configuration includes an internal combustion engine 20, generator 32, and electric traction motor 36 combined to produce the vehicle's output shaft torque. The invention has a set of vehicle state sensors and communication interfaces connected independently to a main controller 200 and an independent plausibility check (IPC) 202. The IPC monitors and mitigates the powertrain output shaft torque (OST) by reducing powertrain torque when the detected OST is greater than the desired OST. The IPC has a second mode of operation to shut down the powertrain OST of the HEV powertrain when a fault or failure is detected. Additional features include a quizzer 204 function to continuously verify the functionality of the IPC.
