摘要： A shift control apparatus for a motor vehicle including an internal combustion engine and a continuously variable transmission (CVT) is provided for controlling the speed ratio of the CVT depending upon operating conditions of the vehicle. The control apparatus determines whether an electronic throttle valve of the engine is at fault or not, and restricts the speed ratio of the CVT when the throttle valve is at fault such that the input-side rotation speed of the transmission is variable within a range that is narrower than a range in which the rotation speed is variable during normal running of the vehicle. The range of the input-side rotation speed may be defined by the upper limit, or the lower limit, or both the upper limit and the lower limit.

摘要： A control apparatus is provided in a vehicle equipped with a power source and a continuously variable transmission. The continuously variable transmission is connected to the power source. The control apparatus includes a target power determinator, a target revolutions determinator, a determining device, a setting device and a target torque determinator. The target power determinator determines a target power of the power source. The target revolutions determinator determines target revolutions on the basis of the target power. The determining device determines whether the vehicle is a transient driving condition or not. The setting device sets the target revolutions as setting revolutions when the determining device determines that the vehicle is not in the transient driving condition. The setting device sets revolutions different from the target revolutions as the setting revolutions when the determining device determines that the vehicle is in a transient driving condition. The target torque determinator determines a target output torque of the power source on the basis of the target power and the setting revolutions. Since the vehicle is controlled in accordance with the driving condition of the vehicle, a jerky feeling can be avoided and ride quality or drivability of the vehicle is prevented from being deteriorated, even when the vehicle is in a transient driving condition.
摘要翻译：在配备有电源和无级变速器的车辆中设置有控制装置。无级变速器连接到电源。控制装置包括目标功率确定器，目标转速确定器，确定装置，设定装置和目标转矩确定器。目标功率确定器确定电源的目标功率。目标革命决定者根据目标力确定目标转速。确定装置确定车辆是否是暂时驾驶状况。当确定装置确定车辆不处于暂时驾驶状态时，设定装置将目标转数设定为设定转速。当确定装置确定车辆处于暂时驾驶状态时，设定装置将与目标转数不同的转数设定为设定转速。目标转矩确定器基于目标功率和设定转数来确定电源的目标输出转矩。由于根据车辆的驾驶状况来控制车辆，所以即使在车辆处于暂时驾驶状态的情况下，也可以避免抖动的感觉，并且防止车辆的乘坐质量或驾驶性能劣化。

摘要： A hydraulic control apparatus for controlling a vehicle power transmitting system including a belt-and-pulley type continuously variable transmission and a torque converter provided with a lock-up clutch. The transmission includes a pair of hydraulic actuators one of which receives a belt tensioning pressure for controlling a tension of a transmission belt. The hydraulic control apparatus includes a lock-up clutch control valve which is selectively placed in an engaging and a releasing position for engaging and releasing the lock-up clutch, respectively, a slip control valve for controlling an amount of slipping of the lock-up clutch until the clutch is fully engaged, a pressure control device for raising the belt tensioning pressure so as to increase the tension of the transmission belt; and a pilot-pressure generating device for applying a pilot pressure simultaneously to the slip control valve and the pressure control means, so that the belt tensioning pressure is raised while the slip control valve controls the amount of slipping of the lock-up clutch.

摘要： A hydraulic control apparatus for a power transmitting system for an automotive vehicle having a continuously variable transmission which has a first and a second shaft, a pair of variable-diameter pulleys provided on the first and second shafts, a belt connecting the pulleys, and a pair of hydraulic actuators for changing diameters of the pulleys, wherein a tension of the belt is controlled by regulating an actuating pressure in a driven side actuator of the hydraulic actuators which is provided on a driven one of the two shafts. The apparatus includes a pressure regulating valve which has a valve spool for regulating the actuating pressure in the driven side actuator, and a pressure-reducing chamber for receiving a pressure-reducing pilot pressure for biasing the spool for reducing the actuating pressure. The apparatus further includes a pilot pressure generator for generating the pressure-reducing pilot pressure to be applied to the pressure-reducing chamber, when the detected vehicle running speed exceeds a predetermined value.

摘要： A printer has a printing mechanism for printing on printing paper in accordance with data stored in a buffer memory which is divided into a non-overwrite memory region and an overwrite memory region. The data entered from an external device is first stored in the non-overwrite memory region of the buffer memory. If the data in the non-overwrite memory region exceeds the storage capacity during printing, the excess data is stored in the overwrite memory region. When the data stored in the overwrite memory region exceeds the storage capacity, the printer overwrites subsequent data entered from the external device onto the previous data stored therein. Moreover, during reprinting, the data in the non-overwrite memory region of the buffer memory is read to activate the printing mechanism.
