  • Method of braking force distribution and braking force control system for vehicle
    Patent number: 7661773
    Abstract: A method of braking force distribution and a braking force control system for a vehicle provide a proper control on distribution between braking force between front wheels and rear wheels by controlling braking force on a rear right wheel and a rear left wheel such that an actual wheel speed of each rear wheel follows a target wheel speed thereof. The method includes the steps of calculating a current target wheel speed of each rear wheel to be used based on an actual deceleration speed of at least one of the front wheels and a previous target wheel speed of each rear wheel; and controlling braking force on each of the rear wheels based on the thus calculated current target wheel speed.

    Patent number: 7603569
    Abstract: A system and method are provided which are necessary for exchanging information among a sales agent a1, user a2 and manufacturer A, for preparing a parts check list on an on-line basis, and for storing information to be provided. If, for example, the sales agent a1 or user a2 wants to acquire information from the manufacturer A, manufacturer A will directly confer a password to sales agent a1 with whom manufacturer A directly deals with, while sales agent a1 will directly confer a password to user a2 with whom sales agent a1 directly deals with, on behalf of manufacturer A. This arrangement makes it possible to easily and securely provide, to a specified information seeker, information required by that information seeker.
