Vehicle control system

A vehicle control system, which is configured to calculate an acceleration value used to judge a vehicle behavior and to judge a driving preference of a driver based on the calculated acceleration value, comprising:

• a calculator that is configured to calculate the acceleration value on the basis of:
• a parameter including at least any one of:
• (i) a ratio of the actual longitudinal acceleration of the vehicle to a maximum longitudinal acceleration possible to be established at a moment when the longitudinal acceleration is calculated,
• (ii) a ratio of a depression amount of the accelerator pedal to establish the actual acceleration to a maximum depression amount of the accelerator pedal, and
• (iii) a ratio of a target longitudinal acceleration calculated based on the depression amount of the accelerator pedal to the maximum longitudinal acceleration possible to be established at a moment when the target longitudinal acceleration is calculated, and
• an actual longitudinal acceleration;
• and
• a corrector that is configured to:
• carry out a first correction when the longitudinal acceleration of the vehicle is easy to be established, wherein the first correction comprises:
• correcting the parameter by reducing the acceleration value to be smaller than the acceleration value when the longitudinal acceleration of the vehicle is difficult to be established, and
• correcting the actual longitudinal acceleration by increasing the acceleration value to be larger than the acceleration value when the longitudinal acceleration of the vehicle is difficult to be established;
• and
• carry out a second correction when the longitudinal acceleration of the vehicle is difficult to be established, wherein the second correction comprises:
• correcting the parameter by increasing the acceleration value to be larger than the acceleration value when the longitudinal acceleration of the vehicle is easy to be established, and
• correcting the actual longitudinal acceleration by reducing the acceleration value to be smaller than the acceleration value when the longitudinal acceleration of the vehicle is easy to be established.
