摘要:
In a vehicle equipped with a continuously variable transmission, sensors detect a vehicle speed, an accelerator depression degree and an output rotation speed of the transmission. The minimum required drive shaft drive torque is calculated from the vehicle speed and the accelerator depression degree. A target input rotation speed of the transmission for achieving the minimum required drive shaft drive torque with the least engine fuel consumption is calculated according to the vehicle speed. The input rotation speed is controlled to this target input rotation speed. The target engine output torque to generate the minimum required drive shaft drive torque is calculated, and an engine throttle opening is controlled to obtain this torque. As a result, the required vehicle drive force is obtained with the minimum engine fuel consumption.

An integrated control system for both an electronically-controlled engine and a steplessly variable automatic transmission, comprises a speed-change ratio arithmetic processing section for calculating the speed-change ratio as a ratio of the transmission input speed to the transmission output speed, a target driving torque arithmetic processing section for retrieving a target driving torque, based on both the accelerator operating amount and the vehicle speed, from a first predetermined characteristic map, and a target speed-change ratio arithmetic processing section for retrieving a target speed-change ratio, based on both the accelerator operating amount and the vehicle speed, from a second predetermined characteristic map. Also provided is a target engine output torque arithmetic processing section for calculating a target engine output torque, based on all of the target driving torque, the speed-change ratio, and a speed ratio of the transmission input speed to the engine speed. Depending on the engine speed and the target engine output torque, the throttle opening and the transmission input speed are both feedback-controlled.

摘要:
A person authentication system capable of performing personal authentication by comparing templates that is personal identification data with sampling information input by a user is disclosed. For example, a service provider (SP) or a user device (UD) acquires the templates from a person identification certificate (IDC) generated by a personal identification certificate authority that is a third party to thereby perform personal authentication. The IDC stores data, such as a certificate identifier and a user identifier, in accordance with a format, and also stores encrypted templates in a manner that the data can be decrypted by an entity that performs authentication. This arrangement achieves efficient template retrieval and a personal authentication process, as well as effective prevention of the templates from being leaking out.
摘要:
Disclosed are a person authentication system, a person authentication method, and an information processing apparatus which allow person authentication to be performed in an easy fashion in various devices by comparing a template serving as person identification data with sampling information input by a user. A service provider (SP) or user device (UD) executes person authentication by acquiring a template from a person identification certificate (IDC) generated by a third-party agency serving as a person identification certificate authority (IDA). The IDA acquires a template serving as identification data after verifying a person requesting an IDC to be issued, and generates the IDC storing template information. The IDA distributes the IDC having a digital signature of the IDA added thereto to the SP and the UD.

摘要:
The present invention provides a novel configuration which allows devices capable of processing different signature algorithms to mutually verify public key certificates. In this configuration, public key certificates storing plural signatures based on different signature algorithms such as RSA and ECC are issued and each device selects a signature which can be processed (namely, verified) by itself and verifies the selected signature. Consequently, the novel configuration allows the devices each being capable of verifying only a different signature algorithm to verify the public key certificates of the other devices, so that each device can perform public key certificate verification in the cross-certification and encrypted data communication not only with the other devices having public key certificates attached with signatures based on the same signature algorithm as that of each device, but also with the other devices or providers having public key certificates attached with signatures based on different signature algorithms from that of each device, thereby significantly enhancing the reliability in communication.
