A driving support system for a vehicle comprising: a recognition unit configured to recognize a solid object existing in a direction of movement of a subject vehicle ; a support control unit configured to perform turning control of the subject vehicle for avoiding a collision between the solid object and the subject vehicle based on a travel state of the subject vehicle , in cases where an existence of the solid object has been recognized by the recognition unit ; and a steering torque generator that serves to apply a steering torque for turning to a steering of the subject vehicle according to a turning command from the support control unit ; characterized by a turning control stop unit configured to stop the turning control by the support control unit , in cases where a correlation between the steering angle of the steering as a vehicle state related to turning of the subject vehicle by the support control unit and the steering torque applied to the steering by the steering torque generator as a value of a predetermined parameter related to the turning control by the support control unit does not belong to a range of normal state set in advance, after the turning control by the support control unit has been started; wherein the normal state with respect to the vehicle state of the subject vehicle is set on the basis of a state where the driver does not have a strange or uncomfortable feeling based on a standard range of variation in the friction of the traveling road surface; wherein the correlation is the correlation between the steering torque generated by the steering torque generator and the steering angle of the steering. a recognition unit configured to recognize a solid object existing in a direction of movement of a subject vehicle ; a support control unit configured to perform turning control of the subject vehicle for avoiding a collision between the solid object and the subject vehicle based on a travel state of the subject vehicle , in cases where an existence of the solid object has been recognized by the recognition unit ; and a steering torque generator that serves to apply a steering torque for turning to a steering of the subject vehicle according to a turning command from the support control unit ; characterized by a turning control stop unit configured to stop the turning control by the support control unit , in cases where a correlation between the steering angle of the steering as a vehicle state related to turning of the subject vehicle by the support control unit and the steering torque applied to the steering by the steering torque generator as a value of a predetermined parameter related to the turning control by the support control unit does not belong to a range of normal state set in advance, after the turning control by the support control unit has been started; wherein the normal state with respect to the vehicle state of the subject vehicle is set on the basis of a state where the driver does not have a strange or uncomfortable feeling based on a standard range of variation in the friction of the traveling road surface; wherein the correlation is the correlation between the steering torque generated by the steering torque generator and the steering angle of the steering. <EOS>
