PURPOSE:To correct a driving characteristic change which is felt unfavorable by a driver and adaptively change the driving characteristic of a vehicle by providing such a constitution as analyzing the accelerator operation of the driver after the driving characteristic change of the vehicle and judging the suitability of the change. CONSTITUTION:When the driving characteristic of a vehicle is actively changed, the accelerator operation quantity of a driver is sampled by an accelerator operation quantity sampling means (a), frequency analysis of the accelerator quantity is conducted every sampling of a determined number, the resulting spectrum pattern is detected by a spectrum pattern detecting means (b), and its evaluation value is calculated by an evaluation value calculating means (c). The time change quantity of the evaluation value of the spectrum pattern is calculated by a change quantity calculating means (d), and when the change quantity is larger than a determined value, the change of the driving characteristic of the vehicle is judged unsuitable to the driver, and correction is carried out by a correcting means (e) to return the driving characteristic of the vehicle to the original form. |
