The disclosed 2H-pyrimido[4,5-d][1,3]oxazine-2,4(1H)-dione derivatives are intermediates useful in the production of 7,8-dihydro-2,5,8-trisubstituted-7-oxo-pyrido[2,3-d]pyrimidine-6-carboxylic acid derivatives which are gastric anti-secretory agents and anti-allergic agents.
摘要:
A powertrain system including a multi-mode transmission is configured to transfer torque among an input member, torque machines and an output member. A method for controlling the multi-mode transmission includes employing a closed-loop speed control system to determine torque commands for physical torque actuators including the torque machines. The closed-loop speed control system includes employing a virtual torque actuator control scheme to generate torque commands for the physical torque actuators responsive to output commands for a plurality of virtual torque actuators.
