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