  • Patent number: 8909386
    Abstract: In a vehicle control system, an index used to set a running characteristic of a vehicle is obtained based on a running condition of the vehicle. A change of the index that makes behavior of the vehicle crisper is more likely to occur than a change of the index that makes the behavior of the vehicle milder. When it is determined that the vehicle is in a turning condition, the change of the index or a change of the miming characteristic based on the index is less likely to occur than when it is determined that the vehicle is not in the turning condition.

  • Patent number: 8831819
    Abstract: The running control device and method according to the present invention are those for determining abnormality of a longitudinal acceleration sensor which detects vehicular longitudinal acceleration that is used in a vehicle running control. An integrated value of a vehicular longitudinal acceleration that is detected by the longitudinal acceleration sensor is calculated, and determination whether or not the longitudinal acceleration sensor is abnormal is conducted on the basis of the integrated value and a vehicle speed based on vehicle wheel speeds. The calculation of the integrated value is initiated when a situation where the vehicle speed based on vehicle wheel speeds is zero and the increasing rate of the detected vehicular longitudinal acceleration is equal to or larger than a reference value for the increasing rate continues for a period which is equal to or larger than a reference value for the initiation of calculation.
