  • Publication number: 20230169436
    Abstract: Evaluators evaluates an evaluation target via a network, and the obtained evaluation data is stored in a server using identifiers. Judgement by judges regarding a magnitude of a persuasive power of each evaluator is performed via the network in a manner in which the evaluator cannot be identified, and the obtained judgement data is stored in the server using identifiers. The magnitude of the persuasive power of the evaluators is ranked based on the judgement data, and stored in the server using identifiers. A weighted evaluation distribution for the evaluation target is calculated and stored in the server based on the evaluation by each evaluator stored in the server and the rating regarding the magnitude of the persuasive power of each evaluator, provided that as the rating regarding the magnitude of the persuasive power of the evaluator is higher, a greater weighting is given to the evaluation by the evaluator.

  • Patent number: 5291802
    Abstract: A control system for the engine and the automatic transmission of the automotive vehicle is arranged such that the torque of the engine is reduced by delaying the timing of ignition at the time of a shift of the automatic transmission with a multi-stage shift mechanism. The amount of the absorbed inertia at the time of the shift is computed as an amount corresponding to changes of the numbers of revolutions on the input side of the multi-stage shift mechanism prior to and subsequent to the shift thereof. The timing of ignition is so adapted as to be delayed in accordance with the amount of the resulting amount of the absorbed inertia.
