  • Patent number: 9090245
    Abstract: A system according to the principles of the present disclosure includes an axle torque determination module, an engine torque determination module, a torque security module, and an engine torque control module. The axle torque determination module determines an axle torque request based on a driver input and a vehicle speed. The engine torque determination module determines an engine torque request based on the axle torque request and at least one of a first turbine speed and whether a clutch of a torque converter is applied. The torque security module determines a secured torque request based on at least one of the driver input, the vehicle speed, and an engine speed. The engine torque control module controls an amount of torque produced by an engine based on one of the engine torque request and the secured torque request.

  • Patent number: 8594904
    Abstract: 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.

  • Patent number: 8566002
    Abstract: 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.
