摘要： PROBLEM TO BE SOLVED: To provide a system and a method of controlling a forecasted load. SOLUTION: A forecasted load control system is provided. This forecasted load control system comprises a power source to be operated to generate an output of power and having a desirable operation range. A transmission provided with a driving member is engaged with the power source freely to be operated. A control system is communicated with the power source and the transmission. The control system receives at least one input showing a load to be applied to the transmission, and operates to discriminate a change of the load to be applied to the transmission on the basis of the input load. The control system, furthermore, decides a desirable output of power of the power source, which can change a load to be applied to the transmission, and in the case wherein the power source is operated outside the desirable operation range due to a change of the load to be applied to the transmission, the control system can correct performance characteristic of the power source to generate the desirable output of power.

摘要： PROBLEM TO BE SOLVED: To provide a retard control method for electric drive machinery, in the retard control for propulsive machinery which has an electric drive section. SOLUTION: The method for making the power in the propulsive machinery which has the electric drive section dissipate, includes a step which changes into electric power the power which is not desired by the electric drive section; and a step which drives an internal combustion engine with at least one part of electric power, before making the power dissipate substantially with other arbitrary power dissipation devices. Thus, more excellent fuel efficiency is attained by reducing the need for the fuel for an internal combustion engine 14, when the internal combustion engine 14 is driven with a dynamo 16. In such a way that the power dissipation is diffused for among two or more components of a propulsive machinery 10, each life of the power dissipation device containing a brake 34 is prolonged.

摘要： PROBLEM TO BE SOLVED: To provide a hunting preventing system and method for a parallel passage variable transmission.
SOLUTION: The system and method for virtually controlling vibration at a transmission gear ratio is disclosed. When shift is performed at a synchronizing point of substantially making antihunting hysteretic schemes impractical use, disclosed technology is selectively combined to actualize vibration control with a lock-out timer which can cancel it. During gradient navigation and other similar loading scenarios when any operation standards are satisfied, the vibration control can selectively lock the transmission.

摘要： PROBLEM TO BE SOLVED: To solve undesirable and strong jerk caused by sudden change of velocity outputted in a machine for transferring sediment using a hydraulic transmission. SOLUTION: This control device has a transmission velocity sensor 80 for generating an actual velocity signal according to measured velocity of an output shaft of a continuously variable transmission 16. The control device has a first input device, that is, a velocity pedal capable of being at any position within a continuous position range and generating a target velocity signal corresponding to the pedal position. The control device also has a microprocessor controller 18 working so as to receive the target velocity signal and then the actual velocity signal (from the velocity pedal) followed by calculating a command acceleration ac to generate a command velocity Vc based on the target velocity signal, a jerk value j, and the command acceleration ac.
