PROBLEM TO BE SOLVED: To improve steering feeling when operation of a braking force control device is prohibited in a vehicle equipped with an electric power steering device for assisting steering operation for avoiding collision. SOLUTION: The obstacle avoidance assistance device includes the braking force control device 1 and the electric power steering device 2. The braking force control device 1 controls vehicle motion by controlling the braking force of wheels. The braking force control device 1 has a braking force control cutoff switch 15 for prohibiting braking force control. The electric power steering device 2 has an EPS basic control part 41 for determining steering assist amount during normal steering, an avoidance operation assistance control part 42 for correcting the steering assist amount in a direction to avoid collision to the obstacle when an obstacle is detected in front of the vehicle, and an avoidance operation assistance stop/operation processing part 43. When the braking force control cutoff switch 15 is switched on, assistance of steering operation for avoiding collision by the electric power steering device 2 is prohibited.
