Vehicle control system

A vehicle control system, comprising:

• 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;
• a control device (31) configured to control the braking force generated by the braking force generating device;
• and
• a vehicle state information acquisition device (33, 34) configured to acquire vehicle state information including at least a traveling speed of the vehicle and a steering angle of the front wheels, the vehicle state information acquisition device comprising a vehicle speed sensor that detects a traveling speed of the vehicle, and at least one of a steering angle sensor that detects a steering angle of the front wheels and a steering angular velocity sensor that detects the steering angular velocity;
• wherein the control device includes
• an additional deceleration calculation unit (43) that calculates an additional deceleration (Gxadd) to be generated in the vehicle according to the vehicle state information,
• a correction coefficient setting unit (46) that calculates a requested fore and aft acceleration (Gxr) according to a requested fore and aft force (Fxr) for the vehicle, and obtains a correction coefficient (K) for weakening the additional deceleration according to the requested fore and aft acceleration,
• an additional deceleration correction unit (44) that corrects the additional deceleration by the correction coefficient, and
• an additional braking force calculation unit (45) that calculates an additional braking force (Fbadd) to be generated by the braking force generating device according to the additional deceleration corrected by the additional deceleration correction unit,
• wherein the control device causes the braking force generating device to generate the additional braking force calculated by the additional braking force calculation unit, and
• wherein the vehicle state information includes lateral jerk (Jy), and the correction coefficient setting unit (46) sets a lateral jerk correction coefficient (Kj) as a value that gets smaller as the lateral jerk increases, and corrects the correction coefficient (K) by the lateral jerk correction coefficient.
