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 card-feeding mechanism has two rollers positioned before a limiting device, and a roller and a sensor positioned after the limiting device. When a motor rotates clockwise, a transmission device drives the three rollers simultaneously to deliver a card from a front end toward a rear end. When the sensor detects an edge of the card, the motor rotates counterclockwise, and only drives the roller after the limiting device. Then, the card is only driven by the roller after the limiting device, and the rollers before the limiting device are driven by the card.
