摘要： Engine (1) output speed is controlled for optimum efficiency by adjustment of input speed of a continuously variable transmission (CVT) (3). Where power in excess of that provided by the engine (1) is required, additional power is input to the drive train from a fluidic motor (7) driven by fluid pressure stored in an accumulator (6). In driving conditions where the engine (1), operating at optimum efficiency, produces power in excess of that demanded by the vehicle, the fluidic motor (7) is reversed for operation as a pump and excess engine power is utilized to drive the pump (7) and store energy in the accumulator (6) in the form of fluid pressure. A CPU (18) determines power output required of the engine (1) as a sum of that indicated by a sensor (14) which senses power demanded of the vehicle by a driver and an increment of power required to maintain the pressure of the accumulator (6) above a threshold amount.
