  • Patent number: 11958465
    Abstract: The vehicle control system includes a braking force generating device (6, 22) configured to generate a braking force to shift a load of a vehicle to a side of front wheels thereof at an initial stage of a cornering, and a control device (31) configured to control the braking force generated by the braking force generating device. The control device calculates an additional deceleration (Gxadd) according to vehicle state information, calculates a lateral jerk equivalent value (Jy) according to the vehicle state information, and sets a lateral jerk correction coefficient (Kj) for weakening the additional deceleration. The control device corrects the additional deceleration by the lateral jerk correction coefficient (K), and calculates an additional braking force (Fbadd) to be generated by the braking force generating device according to the corrected additional deceleration.
