DRIVING SUPPORT SYSTEM

The invention relates to a driving support system that supports driving of a vehicle executes steering support control that steers the vehicle in a first direction away from a risk factor in front of the vehicle. A target steering amount in the steering support control is represented by a function of a relative relationship parameter including a lateral distance between the vehicle and the risk factor. A straight road is a road having a curvature less than a first curvature. A curved road is a road having a curvature equal to or greater than the first curvature. When a road ahead from the vehicle to the risk factor includes the curved road, the driving support system reduces the target steering amount for the same relative relationship parameter or advances a start timing of the steering support control as compared to when the road ahead is the straight road. 本发明涉及辅助进行车辆驾驶的驾驶辅助系统，驾驶辅助系统执行使车辆向从车辆前方的风险因素离开的第1方向转向的转向辅助控制。转向辅助控制中的目标转向量由包括车辆与风险因素之间的横向距离的相对关系参数的函数表示。直路是曲率小于第1曲率的道路。弯道是曲率大于等于第1曲率的道路。在从车辆到风险因素的前方道路包括弯
