摘要:
A hydraulic motor/pump regenerator system for recovering energy from the moving vehicle having high efficiency and precise control, thereby allowing the maximum amount of energy to be recovered and reused, is described. Three, fixed-displacement pump/motors are used to enable the system to recover and reapply energy at efficiencies expected to be above 70% in most circumstances. The invention is not limited to the use of three fixed displacement hydraulic units since using more units may in some drive cycles further improve efficiency. By selecting an appropriate combination of pump/motor units for providing the driveshaft (4d) torque required by the driver, embodiments of the present invention generate high recovery efficiency at any speed.
摘要:
A control system/method controls a vehicular automated transmission system so as to overcome a tooth butt condition. The automated transmission system including an internal combustion engine having an engine output member, a multiple speed change gear transmission having an input shaft, a centrifugal friction clutch for drivingly connecting said engine output member to said input shaft, a throttle responsive to manually requesting of a degree of engine fueling, and a system controller. The system controller varies the engine speed to encourage gear engagement upon sensing the tooth butt condition.
