A driving force control system for a vehicle having a mechanism for changing an engine speed continuously. The driving force control system basically controls said mechanism in a manner such that the engine speed is adjusted to optimize fuel economy. The driving force control system is configured to determine an index representing a demand to enhance agility of behavior of the vehicle based on an actual behavior of the vehicle or an amount of operation carried out by a driver to cause said behavior. An upper limit value of the engine speed of the case in which a drive demand is increased is determined on the basis of the index, and the upper limit value is set to the higher value with an increase in the index representing the demand to enhance agility of behavior of the vehicle.

摘要:
A vehicle control system configured to judge a vehicle behavior or a driving preference of a driver based on acceleration of the vehicle including at least longitudinal acceleration. An acceleration value used in the judgment is obtained on the basis of a weighted detection value of the actual longitudinal acceleration of the vehicle, and a weighted parameter which is varied by an operation to increase a driving force of the vehicle executed by the driver. A weight on the parameter is reduced in case a weight on the detection value of the longitudinal acceleration is increased, and the weight on the parameter is increased in case the weight on the detection value of the longitudinal acceleration is reduced.

A vehicle control system includes: a controller that configured to obtain an index on the basis of a running condition of a vehicle and that configured to vary a running characteristic of the vehicle on the basis of the index, wherein the controller is configured to relatively delay a variation in the index in response to a variation in the running condition when the variation in the index decreases quickness of a behavior of the vehicle as compared with when the variation in the index increases the quickness of the behavior of the vehicle, and to correct the running characteristic on the basis of the index so that energy efficiency of a driving force source of the vehicle varies within a predetermined range depending on control over power output from the driving force source.
摘要:
A vehicle control system includes a control portion configured to determine a single parameter based on a running condition of a vehicle, and determine control amounts for a plurality of actuators provided in the vehicle based on the parameter. A relation of the control amount for each of the plurality of actuators to the parameter is predetermined. The control portion is configured to, when the parameter is determined, determine the control amounts for the respective actuators based on the parameter, and control the actuators based on the determined control amounts.
摘要:
A vehicle control system configured to estimate an index representing a driving condition of a vehicle and a driving preference of a driver based on acceleration of the vehicle, and to adjust a driving characteristics of the vehicle based on the index. The vehicle control system is comprised of a straight-line braking determining means configured to determine a fact that a braking operation of the vehicle is carried out under a condition that the vehicle travels in a straight line, and an operational disturbance reducing means that prevents or reduces an effect of a disturbance resulting from the straight-line braking of the vehicle on an adjustment of the driving characteristics of the vehicle.
摘要:
A vehicle control system vehicle control system configured to adjust a control characteristic of a vehicle in accordance with a driving preference of a driver. The vehicle control system detects an intentional operation of the driver based on a pattern of a change in a speed of an operation carried out by the driver to change a driving condition of the vehicle, and judges the driving preference on the basis of: a correlation of operational preference determining a correlation among an operating amount, an operating time and an operating preference; an operating amount of the intentional operation; and an operating time of the intentional operation. Therefore, the driving preference can be judged immediately when the driver carries out an operation to change a driving condition of the vehicle based on the operating time and the operating amount. The judged driving preference is reflected on the control characteristic of the vehicle immediately.
摘要:
A vehicle control system capable of improving drivability by reflecting driving environment and driving preference accurately on driving characteristics. The vehicle control system is configured to change an index for setting driving characteristics of the vehicle. When accelerations Gx and Gy are changed, a sportiness index is changed in a different manner depending on a detail of an operation for changing accelerations Gx and Gy executed by a driver, thereby reflecting the driving preference of the driver appearing on the operation can be reflected on sportiness of the vehicle.
