  • Vehicle body drifting restraining device
    Patent number: 8170754
    Abstract: A vehicle body drifting restraining device which restrains a drifting of a vehicle body, wherein: when a brake control device operation prohibition switch, which prohibits an operation of a brake control device, is in a state of prohibition, a control for restraining the drifting of the vehicle body is prohibited.
    Type: Grant

  • Vehicle state value detecting device
    Patent number: 7825786
    Abstract: The vehicle state value detecting device includes a first low pass filter (32, 36) and a second low pass filter (33, 37) having a lower cutoff frequency than the first low pass filter. The device processes a detection signal of a sensor (10, 11) for a motion control of a vehicle such as a yaw rate sensor and a lateral G sensor by selectively using one of the two low pass filters. A signal selecting unit (35, 39) selects the output of the first low pass filter when the control process demands prompt detection of an abrupt changes in the behavior of the vehicle and the output of the second low pass filter when it is not the case and an enhanced stability of the control action has a priority.
