To provide a driving support device capable of turning a vehicle to avoid an obstacle even on a road surface with a small frictional coefficient.SOLUTION: At a time point t1, when a driver of a vehicle VC (1) foresees a collision with a vehicle VC (2) in front and quickly steps on a brake, hydraulic fluid pressure Pwc of a brake actuator rises sharply. Upon determination that there is a possibility of the collision with the vehicle VC (2), the CPU sets a steering angle command value θs* for causing the vehicle VC (1) to travel into an area Aa where the collision is avoidable, and controls a steering angle θs to become the steering angle command value θs*. Then, if slip is occurring, the CPU reduces the pressure Pwc of the brake actuator at a time point t3 when the steering angle θs becomes the steering angle command value θs*. This operation secures lateral force of tires to turn the vehicle VC (1).SELECTED DRAWING: Figure 5

    【課題】摩擦係数が小さい路面であっても障害物回避のために車両を旋回させることができるようにした運転支援装置を提供する。【解決手段】時刻t1において、車両VC(1)の運転者が前方の車両VC(2)との衝突を予見して急ブレーキを踏むとブレーキアクチュエータの作動油の圧力Pwcが急上昇する。CPUは、車両VC(2)に衝突する可能性があると判定すると、衝突を回避可能な領域Aaへと車両VC(1)を走行させるための転舵角指令値θs*を設定し、転舵角θsを転舵角指令値θs*に制御する。そして、CPUは、すべりが生じている場合、転舵角θsが転舵角指令値θs*となる時刻t3において、ブレーキアクチュエータの圧力Pwcを低下させる。これにより、タイヤの横力を確保し、車両VC(1)を旋回させる。【選択図】図5
