  • Patent number: 8977461
    Abstract: When the operating speed of an accelerator pedal is higher than a given operating speed, a target acceleration as a target output value is multiplied by a gain so that an absolute value of the target acceleration is increased; therefore, a large acceleration requested by the driver can be achieved. The gain by which the target acceleration is multiplied is set to 1 when the target acceleration is about zero, so as to resume a condition where the absolute value of the target acceleration is not increased. Thus, when the control of increasing the absolute value of the target acceleration with the gain is stopped, an elevation change is less likely or unlikely to occur in the actual acceleration. Consequently, a desired acceleration is generated without causing the driver to feel uncomfortable during driving of the vehicle.

  • 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: 8566008
    Abstract: A control device for an internal-combustion engine designed to ensure that required responsiveness is obtained as actual torque responsiveness with respect to a torque demand even when the torque responsiveness with respect to the actuation of a particular actuator is affected by the operating conditions. A response compensating filter is provided at a preceding stage to an air inverse model, and the target torque which has been corrected by the response compensating filter is converted by the air inverse model to obtain a target opening degree of a throttle. A time constant of the response compensating filter is set on the basis of the operating conditions of the internal-combustion engine so that the responsiveness of actual torque with respect to the torque demand reaches a preset standard responsiveness.
