Driving support system for a vehicle

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;
• a turning control stop unit configured to stop the turning control by the support control unit, in cases where a correlation between a vehicle state related to turning of the subject vehicle by the support control unit and 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;
• 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;
• wherein the turning control stop unit stops the turning control by the support control unit, in cases where a correlation between at least any among a steering angle of the steering, a yaw rate of the subject vehicle, and a transverse acceleration acting on the subject vehicle, as a parameter indicating the vehicle state, and the steering torque applied to the steering by means of the steering torque generator does not belong to the range of normal state;
• and
• the range of normal state is set to correspond to the steering torque, based on an operating state of the steering which the driver of the subject vehicle can permit, at the time when the turning control is carried out by the support control unit.
