VEHICLE DRIVING SUPPORT CONTROL DEVICE

There is provided a structure in a driving support system of a vehicle equipped with a steering assist mechanism and a torque vectoring mechanism of right and left wheels, the system capable of reducing an occurrence of a driver's sense of incongruity as much as possible also during the operation of a control based on a machine input and reflecting a driver's steering in the control. The inventive device comprises a steering assist torque controller which controls a steering assist torque given by the steering assist mechanism, a right and left braking-driving force difference controller which controls the braking-driving force difference between the right and left wheels given by the torque vectoring mechanism and a control target value determiner which determines the target values of the steering assist torque and braking-driving force difference for driving support control, based on the steering torque by the driver.
