Vehicle control apparatus

A vehicle control apparatus comprising:

• road wheel speed sensors which detect road wheel speeds of respective road wheels of a vehicle;
• a vehicle body speed calculating section configured to calculate a vehicle body speed on the basis of the detected road wheel speeds;
• a slip ratio calculating section configured to calculate slip ratios which are ratios of the respective road wheel speeds with respect to the vehicle body speed;
• an anti-skid brake control section configured to control wheel cylinder fluid pressures for respective wheel cylinders such that the slip ratios fall within a predetermined range;
• a wheel cylinder fluid pressure acquiring section configured to acquire the wheel cylinder fluid pressures;
• a wheel cylinder fluid pressure correction value calculating section configured to correct the acquired wheel cylinder fluid pressures in accordance with an operating state of the anti-skid brake control section;
• damping force variable shock absorbers disposed between the respective road wheels and the vehicle body, the damping force variable shock absorbers being constructed to variably adjust respective damping force characteristics thereof;
• and
• a damping force variable shock absorber control section configured to set the damping force characteristics in accordance with wheel cylinder fluid pressure correction values obtained as the corrected wheel cylinder fluid pressures.
