Patent number: 9079574Abstract: The invention is concerned with control of a motor vehicle powertrain having a transmission of torque-controlled type. The powertrain also has an engine which provides a controllable engine torque. The method involves determining a reaction torque requirement and an engine torque requirement suitable to create a desired wheel torque and also a desired engine acceleration. The engine torque and the reaction torque provided by the transmission are set accordingly. The invention is characterized by the fact that the aforementioned calculation involves estimating and allowing for vehicle acceleration.Type: GrantFiled: August 8, 2005Date of Patent: July 14, 2015Assignee: Torotrak (Development) LimitedInventors: Matthew Piers Burke, Matthew Gibson Field

Patent number: 8892315Abstract: A method for controlling a continuously variable ratio transmission is described. The method may include controlling a continuously variable ratio unit (“variator”) having rotary input and output members through which the variator is coupled between an engine and a driven component, the variator receiving a primary control signal and being constructed and arranged to exert upon its input and output members torques which correspond directly to the control signal. The method may also include determining a target engine acceleration, determining settings of the variator's primary control signal and of an engine torque control for providing the required engine acceleration and adjusting the control signal and/or the engine torque control based on these settings, predicting a consequent engine speed change, allowing for engine and/or transmission characteristics, and correcting the settings of the control signal and engine torque based on a comparison of actual and predicted engine speeds.Type: GrantFiled: January 11, 2012Date of Patent: November 18, 2014Assignee: Torotrak (Development) LimitedInventors: Matthew Gibson Field, Stephen William Murray, Matthew Piers Burke

Patent number: 8292781Abstract: The invention concerns a method of operating a motor vehicle powertrain comprising an infinitely variable transmission and an engine. The transmission comprises a rotary transmission input coupled to the engine, a rotary transmission output coupled to the vehicle wheels, a variator which provides a continuously variable ratio (the “variator ratio”), and gearing for coupling the variator between the engine and the transmission output in such a manner that the ratio of transmission output speed to transmission input speed (the “reciprocal transmission ratio”) is a function of the variator ratio. The available range of variator ratios maps onto both forward and reverse reciprocal transmission ratios, and at a particular variator ratio (the “geared neutral ratio”) the transmission output is stationary despite its being coupled through the transmission to the rotating transmission input.Type: GrantFiled: January 30, 2006Date of Patent: October 23, 2012Assignee: Torotrak (Development) LimitedInventors: Matthew Gibson Field, Matthew Piers Burke
