Abstract: In an embodiment of the continuously variable transmission control apparatus of the present invention, even if an actual gear change ratio RATIO overshoots a target gear change ratio RATIO T and an upshift gear change instruction (DS1 gear change duty output) is switched to a downshift gear change instruction (DS2 gear change duty output) during gear change due to the upshift gear change instruction, in the case where the upshift gear change speed is fast, specifically, in the case where a maximum actual sheave position change ratio DWDRmax is not less than a determination threshold g, it is determined that the transmission is capable of performing an upshift gear change, and the upshift gear change state is determined to be normal. In this manner, a normalcy determination is performed more frequently.

Abstract: A powertrain control apparatus that controls a powertrain including a lock-up clutch, which connects an engine, in which fuel supply may be cut off, directly to an automatic transmission. The control apparatus includes an output unit, a control unit, and a setting unit. The output unit outputs an instruction to lower engagement pressure for the lock-up clutch from a value at which the lock-up clutch is engaged to a value at which the lock-up clutch is disengaged. The control unit resumes the fuel supply to the engine when a predetermined lag time has elapsed since the instruction is output. The setting unit sets the lag time so that the lag time is shorter when a temperature of a combustion chamber of the engine is a first temperature than when the temperature of the combustion chamber of the engine is a second temperature which is higher than the first temperature.

Abstract: In a controller for a belt-type continuously variable transmission including a hydraulic actuator that changes a groove width of a primary pulley, a hydraulic actuator that changes a groove width of a secondary pulley, and a belt clamping pressure control solenoid that controls the hydraulic pressure supplied to the hydraulic actuator of the secondary pulley, a mechanism calculates a transmission ratio between the primary pulley and the secondary pulley and determines whether or not there is belt slippage based on that calculated transmission ratio, and a mechanism determines normalcy of the belt clamping pressure control solenoid. The input torque when belt slippage has actually occurred, i.e., when a failure has been determined, is used as a condition when performing the normalcy determination.

Abstract: A maximum flow calculating unit calculates a maximum amount of hydraulic fluid that can flow into or out of an input-side hydraulic cylinder when a shift control command signal is set to a reference DUTY value, based on an estimated valve pressure difference calculated by an estimated pressure difference calculating unit, and a post-guard target sheave position setting unit performs a guard process for restricting the amount of change of the sheave position, using a guard value calculated by a guard value calculating unit based on the maximum flow amount, so as to set a post-guard target sheave position. Since the thus set target sheave position does not undergo excessive large changes nor excessively small changes during shifting, a target value for shifting is set so that a feedforward controlled variable determined based on the amount of change of the target sheave position becomes an appropriate value.

Abstract: A diagnostic apparatus and a diagnostic method are provided for a belt squeezing force adjusting mechanism of a continuously variable transmission in which a belt is wound around a primary sheave that receives driving force and a secondary sheave that outputs force to a drive line, and which continuously changes the output rotation speed by adjusting the width of the groove the primary sheave and the secondary sheave by shift control. This diagnostic determines, as a precondition, whether a target control value calculated in shift control is in a low region, and performs a diagnostic on the belt squeezing force adjusting mechanism based on the relationship between an actual control value and the target control value during control to reduce a control value when it is determined that the precondition is satisfied. According to this diagnostic apparatus and diagnostic method, an erroneous diagnosis can be prevented so the diagnostic can be performed accurately.

Abstract: When a mobile telephone requests a web server for HTML page data containing a link, the server generates an identifier and appends the identifier to the link. An HTML page containing the link with the appended identifier is generated by the web server and is transmitted from the web server to the mobile telephone. If content at the link destination of the link is requested by the mobile telephone, then the content is transmitted to the mobile telephone and an access log entry is recorded at the web server. The access log entry includes the identifier and the content request. In a case where identifiers are found to be in common, the number of times this content was accessed (requested) is construed to be a single time. Even if a single item of content is divided into multiple portions and requested multiple times, the number of times this content was accessed is treated as being a single time. The number of times access was performed can be calculated comparatively accurately.

Abstract: A controlling system for a vehicle with a continuously variable transmission, which can render a sufficient accelerating feeling in responsive to a driver's requirement. A controller, upon judgment of an acceleration requirement, sets a target drive force higher than the target drive force upon normal calculation upon normal operation of an accelerator pedal, and sets a target rotation speed for acceleration higher than the target rotation speed upon the normal operation and increasing with an increase of the vehicle speed by a predetermined gradient. The speed change ratio of the continuously variable transmission and the output torque of the engine are controlled such that the set target drive force is achieved, and an input shaft rotation speed of the continuously variable transmission coincides with the target rotation speed for the set acceleration.

Abstract: Preventing malicious code from reading an authenticator and being falsely authenticated using the read authenticator. Authenticator accepting period detection means detects an authenticator accepting period during which inoperativeness of all unauthenticated programs is guaranteed. Program executing means transmits its authenticator only during the authenticator accepting period. After authentication means is authenticated as genuine, the authentication means computes a one-way function value of the authenticator received from the program executing means and compares the one-way function value X with a stored value Y for the program executing means. If X=Y, then the authentication means authenticates the program executing means.

The lock-up clutch is then operated by hydraulic pressure corresponding to the hydraulic-pressure instruction value.

Abstract: A continuously variable transmission 18 changes a speed-change ratio ? so that an actual rotation speed NIN of an input shaft 36 coincides with a target rotation speed NIN* set based on a target output P*. A target output calculating portion 156 calculates a first target drive force related value P1* based on both an acceleration required amount Acc and a load of an auxiliary machine AUX, calculates a second target drive force related value P2* based on the acceleration required amount without considering the auxiliary machine load, and sets the second drive force related value as the drive force related value P* upon a vehicle regular running. Even when the auxiliary machine load fluctuates in the vehicle regular running the target output does not fluctuate, and prevention of fluctuation of the target output rotation speed increases the drivability in the vehicle regular running.
