Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus for further correcting output of acceleration sensors for vehicles and capable of accurately correcting the drift errors of the acceleration sensors. SOLUTION: On the basis of output of the acceleration sensors 90 and 92, when a means (166) for determining a linear cruse over a flat road at a constant speed has determined that a vehicle is cruising linearly over a flat road at a constant speed, the output of the acceleration sensors 90 and 92 is corrected at an acceleration correction means 168. Acceleration values from the acceleration sensors are thus advantageously and corrected accurately, in comparison with a conventional correction device which considers that a vehicle is linearly cruising, when the difference between right and left rotation speeds of the vehicle remains within a prescribed value and takes the output values of the acceleration sensors 90 and 92 at the time as drift errors.

PROBLEM TO BE SOLVED: To determine an integer value bias with high precision, in a short time. SOLUTION: This carrier wave phase type GPS positioning apparatus acquires the data of an accumulated value of a carrier wave phase of a satellite signal of a mobile station side at one time. The apparatus associates the data of the accumulated value of the carrier wave phase of the mobile station side at the one time with the data of the accumulated value of the carrier wave phase of a base station side with a plurality of times, before the one time, to estimate the integral value bias contained in the accumulated value of the carrier wave phase of the satellite signal observed by the mobile station.

Abstract:
PROBLEM TO BE SOLVED: To provide an output corrector of acceleration sensor for vehicle in which drift error of acceleration sensor can be corrected more accurately. SOLUTION: When an engine output decision means 166 makes a decision that the output from an engine 10 falls within a specified range, an acceleration correcting means 168 corrects the outputs from acceleration sensors 90, 92 based on the outputs therefrom. Alternatively, outputs from the acceleration sensors 90, 92 are corrected based on the pavement inclination θ in the longitudinal direction estimated by a pavement inclination estimating means 166. Furthermore, outputs from the acceleration sensors 90, 92 are corrected based on the outputs therefrom when flat road constant speed straight traveling is determined by the means 166. Output from the acceleration sensor can be corrected accurately as compared with a conventional corrector where a decision is made that a vehicle is traveling straight if the difference between left and right rotational speeds falls with a specified range and the outputs from the acceleration sensors 90, 92 are employed as a drift error.

Shortage torque Δtref which is a difference between the command value (command torque) tref found from an equation of motion of a driving system rotor in a motive power transmission route of a vehicle and the actual transmission torque tr is a function of input torque tin of the electromagnetic clutch 30 and a rotational speed difference ΔN.
Abstract:
PROBLEM TO BE SOLVED: To provide a position detector which does not need to repeat a confirmation process of integer bias from the beginning even in the case that switching of a datum satellite and the like occurs. SOLUTION: The position detector sets a datum satellite among a plurality of satellites being observable by the moving station, estimates an integer value bias included in the integrated value of a carrier wave phase of satellite signal from each satellite based on the phase difference of integrated value concerning the other satellite on the basis of the integrated value concerning the datum satellite by using observation data which the moving state observes at every specific period and detects the position of the moving state based on the estimated integer value bias. When the datum satellite becomes unavailable of observation, estimation of integer value bias is executed by determining a new datum satellite other than the previous datum satellite among the plurality of satellites being observable using a past observation data.

Abstract:
PROBLEM TO BE SOLVED: To provide a control device for a vehicular torque distribution clutch improving fuel economy of a vehicle and enhancing durability of the vehicular torque distribution clutch. SOLUTION: A torque distribution clutch control means 120 controls transmission torque tr (=t ref ) of an electromagnetic clutch 30 based on a map value M tindf (V) of a traveling resistance relation quantity, and the fuel economy of the vehicle is improved and durability of electromagnetic clutch is enhanced. That is, since the torque distribution clutch control means 120 reduces the transmission torque tr (=t ref ) toward zero as input torque t in of the electromagnetic clutch 30 reduces, while large torque is distributed through the electromagnetic clutch 30 to enhance acceleration performance when the input torque t in is larger than the map value M tindf (V), engagement load in the electromagnetic clutch is suppressed to further improve fuel economy and enhance the durability of the torque distribution clutch when the input torque t in is smaller than the map value M tindf (V).

Abstract:
PROBLEM TO BE SOLVED: To achieve natural dialogues by creating an appropriate response text considering negative intentions. SOLUTION: When a negative expression determination part 22 determines that no negative expression is included, a result using response creating part 26 creates the response text based on the analysis result. When the negative expression determination part determines that negative expression is included and the preceding response type is "response to inquire object words in parallel", a topic change response creating part 30 creates a response text for changing the topic. When the negative expression determination part determines that negative expression is included and the preceding response type is other than "response to inquire object words in parallel", an affirmative response creating part 32 creates a response text for affirmative response.
