  • Patent number: 6123357
    Abstract: In an airbag system for a vehicle, a seat sensor unit determines the placement state of a child seat on the basis of the radio communication state made between a transponder equipped in the child seat and antennas in a front passenger seat, and the output state of a passenger detection sensor in the front passenger seat, and transmits the determination result to a control unit. The control unit controls the necessity of inflation of a passenger-side airbag and side airbag on the basis of the obtained communication result.

  • Patent number: 6125326
    Abstract: A combination of a main navigation apparatus 2 which is fixed to the vehicle and a sub-navigation apparatus 3 which is detachable from the vehicle. When the sub-navigation apparatus 3 is attached, map information and current position information is displayed on a main display 25 under control of a sub-control unit 1, and state of the vehicle is displayed on a sub-display 33. When detaching the sub-navigation apparatus 3 from the vehicle, area map information necessary for waking outside of the vehicle is transmitted from an on-vehicle database 22 to a RAM 32. When the sub-navigation apparatus is detached from the vehicle, if the operation switch 36 is turned on, either the sub-display 33 or a speaker 34 is operated by an sub-navigation unit in a saving power control mode in which either the sub-display 33 or the speaker 34 is operated only for a predetermined period of time since the operation switch 36 is turned on.

  • Patent number: 6116638
    Abstract: In an airbag system for a vehicle, when the state of a passenger at a front passenger seat (including the attached state of a child seat) can be detected, airbags are controlled on the basis of the detection state (S19, S21), and that detection state is stored in a RAM (S23). When it is detected that one of "position offset" of the child seat, "input signal abnormality", "hardware error", and passenger detection sensor failure has occurred at the front passenger seat (S12-S15), the contents of the RAM are referred to, and the airbags and the like are controlled on the basis of the sensor state one cycle before that state has been detected (S22).

  • Patent number: 6002345
    Abstract: The communication state is evaluated on the basis of the current positions, velocities, and moving directions included in information obtained from another mobile station by radio communications and information of the own mobile station, and the electric field strength Bi of the radio communications (S31 to S34). When the obtained evaluation value is smaller than the relative distance Li between the mobile stations (S35), processing for generating a message in the own mobile station is done in correspondence with the current position (S36 to S42), or processing for generating a message in the other mobile station is done in correspondence with the direction the other mobile station is traveling (S43 to S48).
