Abstract:
1. An engine control system comprising: a driver axle torque request module (DATRM) that determines a pedal torque request based on minimum and maximum scaling torques and a torque scalar, that determines a raw driver torque request, that selectively shapes raw driver torque request into a final driver torque request, and that converts said final driver torque request into a first axle torque request; and a driver axle torque security module (DATSM) that selectively diagnoses a fault in said first axle torque request based on a minimum engine torque, said minimum scaling torque, a first comparison of said final driver torque request and a redundant final driver torque request, and a second comparison of said first axle torque request and a redundant axle torque request.
