20120143398 | VEHICLE CONTROL SYSTEM - 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. | 06-07-2012 |
20120143399 | VEHICLE CONTROL SYSTEM - A vehicle control system obtains an index indicating a running condition of a vehicle on the basis of a vehicle parameter indicating a motion of the vehicle and then sets a running characteristic of the vehicle in accordance with the index. The vehicle control system includes a noise reduction unit that is configured to obtain the index on the basis of the vehicle parameter of which a fluctuating component that fluctuates because of a driver's driving operation or the influence of a running road surface. | 06-07-2012 |
20120179342 | CONTROL DEVICE FOR VEHICLE - In a control device for a vehicle that controls a revolution speed of a drive power source or a gear ratio of a transmission coupled to an output side of the drive power source in the vehicle equipped with the drive power source and the transmission, the control device is configured to determine an index that is based on a running state of the vehicle, and to control a required revolution speed of the drive power source or a required gear ratio for the transmission on the basis of the index. | 07-12-2012 |
20120221228 | VEHICLE CONTROL SYSTEM - In a vehicle control system that obtains an index based on a running condition of a vehicle and changes a running characteristic of the vehicle according to the index, includes index setting means for making a change in the index in response to a change in the running condition in a direction toward crisp running of the vehicle, faster than a change in the index in response to a change in the running condition in such a direction as to reduce crispness with which the vehicle is running. | 08-30-2012 |
20120296541 | VEHICLE CONTROL SYSTEM - 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. | 11-22-2012 |
20120303231 | VEHICLE CONTROL SYSTEM AND VEHICLE CONTROL METHOD - A vehicle control system includes an acceleration generating device (engine, T/M) that generates an acceleration applied to a vehicle, and a vehicle control device that controls the acceleration generating device, based on an accelerator pedal stroke Pa representing an operation of an accelerator pedal by a driver, and a vehicle speed v of the vehicle. In the vehicle control system or method, the vehicle control device controls the acceleration generating device, based on a required acceleration Gx that is determined based on a relationship between the accelerator pedal stroke Pa and the required acceleration, including, as a condition, an acceleration corresponding to a given accelerator pedal stroke, which is specified by a relationship between the vehicle speed and the acceleration when the accelerator pedal stroke is held at the given value. | 11-29-2012 |
