Abstract: A connecting unit including an outer frame member having a pair of hole sections, a pair of first connecting sections and long holes for inserting a controller. The connecting unit further includes a holding frame body which includes through-holes at positions corresponding to the long holes, slide members which include a second connecting section which protrudes and retracts from the pair of hole sections and slide in the extending direction of the long holes by slide operation of the controller, elastic members which bias the slide members to an opposite direction of an insertion direction of the controller and a locking member which locks the slide member at a position where connection between the second connecting section and the first connecting section of the adjacent segment members is released.

Abstract: An apparatus and method for controlling charging and discharging of an energy storage device. If the charging voltage that is applied exceeds a restriction determining voltage, the power value at that time is held as the charging power upper limit value. In addition, by multiplying a restriction coefficient by the charging power upper limit value while gradually reducing the restriction coefficient until the voltage drops below a restriction removal determining voltage. By setting its result as a control target value of the charging power, the charging power is gradually restricted. In contrast, if the applied charging voltage drops below the restriction removal determining voltage, the charging power is conversely gradually restored to its original state using a control target value obtained by multiplying the restriction coefficient by the charging power upper limit value while gradually increasing the restriction coefficient until the voltage equals or goes above the restriction determining voltage.

Abstract: A control system for a hybrid vehicle, which enables the hybrid vehicle to optimally selectively use driven modes to attain excellent fuel economy and thereby make it possible to improve fuel economy. The hybrid vehicle is operated in an engine-driven mode or a motor-driven mode, and recovers electric energy for driving an electric motor, using the output from the engine. The control system calculates a driving fuel consumption amount of the engine required for driving the hybrid vehicle in the engine-driven mode and a recovering fuel consumption amount of the engine required for recovering electric energy to be consumed when the hybrid vehicle is driven in the motor-driven mode, and sets the driven mode to the motor-driven mode when the recovering fuel consumption amount is smaller than the driving fuel consumption amount, and to the engine-driven mode when the former is larger than the latter.

Abstract: A valve control system for an internal combustion engine, which enables the operating mode of a valve system to be switched in optimal timing while preventing the driver from feeling the switching operation so busy and at the same time securing feeling of acceleration, thereby improving drivability. A variable valve-actuating mechanism is capable of selectively switching the operating mode of a valve system including intake valves and an exhaust valve between a plurality of operating modes different in output characteristics. Whether or not the operating mode of the valve system should be switched is determined. The execution of the switching of the operating mode of the valve system based on the determination is suppressed according to a degree of suppression set depending on detected load on the engine.

Abstract: A control apparatus including a requestedtorque calculating device which calculates a torque requested for driving the hybrid vehicle; and a torque control device which controls a torque generated by an engine and a torque generated by an electric motor of the hybrid vehicle based on the requested torque calculated by the requested torque calculating device. The torque control device controls the electric motor so as to generate a torque obtained by subtracting a torque to be generated by the engine from the requested torque. Acoording to this control apparatus, if the responsiveness in changing the transmission ratio of the transmission is poor and the torque generated by the engine becomes lower than therequested torque, the electric motor is controlled to generate the deficient (supplementary) torque, and smooth acceleration of the vehicle can be performed.
