摘要: A control system for an engine includes an engine torque request module, an engine torque response module, a torque command limit module, and an actuation module. The engine torque request module determines an engine torque request based on (i) an engine power request and (ii) a desired engine speed (DRPM). The engine torque response module determines first and second torque values based on (i) an engine torque response model and (ii) first and second torque boundaries, wherein the first and second torque boundaries are based on the DRPM and a measured engine speed (RPM). The torque command limit module generates a secured engine torque request based on (i) the engine torque request and (ii) the first and second torque values. The actuation module controls at least one actuator of the engine based on the secured engine torque request.

摘要: A system includes a power request module, a first desired engine speed (DRPM) determination module, a driver torque request module, and an actuation module. The power request module generates a power request for an engine of the vehicle based on an accelerator pedal position and a vehicle speed. The first DRPM determination module determines a first target DRPM based on the power request, a turbine speed of a torque converter, and a k-factor of the torque converter. The driver torque request module selectively generates a torque request for the engine based on the power request and the first target DRPM. The actuation module controls at least one engine actuator based on the torque request.
