    摘要： A condition of impaired speed and torque control of a parallel electrically variable transmission due to factors beyond nominal modeling and estimation errors is diagnosed under low speed operation. The transmission includes at least one electric machine and a motor torque controller for regulating the transmission input speed and output torque. The motor torque controller includes an open-loop control path based on predetermined torques and accelerations and a closed loop control path based on input speed error. The presence of a larger than expected closed-loop correction magnitude, combined with low output speed and one or more other conditions is used to diagnose a condition of potential torque error, in which case the transmission control is altered to prevent unwanted operation.

    摘要： A method for providing traction control in vehicle powertrain systems is particularly adapted for traction control in a powertrain system of a hybrid electric vehicle comprising an internal combustion engine, an electric machine and a transmission that is operatively coupled to the electric machine and the engine and adapted to provide a transmission torque output in response to a transmission torque input received as a torque output from either or both of the engine and the electric machine. The method is adapted to utilize conventional traction control and engine control hardware, software and communication standards to implement traction control. In one embodiment of the invention, a conventional traction controller is used to detect a wheel spin condition and provide a plurality of first output torque command messages in response thereto. The plurality of first output torque command messages are used to obtain a torque reduction which is applied to a reference output torque to obtain a corresponding plurality of traction control output torque commands for the powertrain system during the wheel spin condition. A rate limit may also be applied to control the rate of change between successive ones of the traction control output torque commands in order to reduce the possibility of extension of the wheel spin condition, or recurrence of another wheel spin condition. Each traction control output torque command may be used to determine an associated traction control engine torque output command and traction control electric machine torque output command.

    摘要： A vehicular powertrain includes operatively coupled engine, electrically variable transmission and driveline. During normal operation when all motors are operating as expected, the engine is operated in a torque control mode in accordance with a torque command provided by a system controller to an engine controller and engine speed is controlled by the motors. During operation when all motors are not operating as expected, the engine is operated in a speed control mode in accordance with a speed command provided by the system controller to the engine controller and engine load torque is controlled by the operative motors.

    摘要： A method of operating a vehicle powertrain system comprising an electric motor and transmission where the electric motor is operably and selectively coupled to the transmission and adapted to provide an output torque contribution thereto, and the electric motor has a predetermined maximum motor output torque and a predetermined minimum motor output torque which are used to determine a range of permissible control points for at least one transmission control parameter. The method includes establishing a motor torque reserve by performing at least one of decreasing the predetermined maximum motor output torque to a maximum reserved motor output torque and increasing the minimum motor output torque to a minimum reserved motor output torque, wherein the maximum reserved motor output torque and the minimum reserved motor output torque are used in place of the predetermined maximum motor output torque and the predetermined minimum motor output torque, respectively, to determine the range of permissible control points for the at least one transmission control parameter. The motor torque reserve may include a static motor torque reserve, a dynamic motor torque reserve, or a combination of both static and dynamic torque reserves. The dynamic torque reserve may include a predictive dynamic reserve, a reactive dynamic reserve, or a combination of a predictive reserve and a reactive reserve or reserves.
