摘要:
An air-per-cylinder (APC) security system for a vehicle comprises an APC determination module, an APC threshold determination module, and an APC diagnostic module. The APC determination module determines first and second APC values for first and second cylinders of an engine, respectively, based on mass airflow (MAF) into the engine. The APC threshold determination module determines an APC threshold based on the first APC value and a spark timing for the first cylinder. The APC diagnostic module selectively diagnoses a fault in the APC determination module when the second APC value is greater than a sum of the first APC value and the APC threshold.

An engine system includes a throttle actuator module and a torque control module. The throttle actuator module controls a throttle actuator based on a desired throttle area. The torque control module determines an actuator torque. The torque control module determines a rate limited torque, a maximum torque, and a minimum torque based on the actuator torque and a predetermined rate of change. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is greater than the maximum torque. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is less than the minimum torque.

A vehicle speed module includes a speed arbitration module that receives at least two of a wheel speed, a transmission output speed (TOS), and an electric motor speed (EMS), and that determines a vehicle speed based on a comparison of the at least two of the wheel speed, the TOS, and the EMS. A speed diagnostic module selectively diagnoses a fault in one of a wheel speed sensor, a TOS sensor, and an EMS sensor based on the comparison.
摘要:
A control module includes a predicted torque control module that determines a desired throttle area based on a transmission torque request and a desired predicted torque. A throttle security module determines a throttle limit based on the desired throttle area and the desired predicted torque and determines an adjusted desired throttle area based on the throttle limit. A throttle actuator module adjusts a throttle based on the adjusted desired throttle area.
摘要:
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.
