COLLISION AVOIDANCE SUPPORT DEVICE AND METHOD

Smart overview of the Invention

A collision avoidance support device is designed to assess the necessity of automatic braking for a vehicle when a potential collision is detected with another vehicle on an intersecting road. The device automatically decelerates the vehicle if it determines that braking is required. A key feature is its ability to adjust the conditions under which braking is triggered, especially when the vehicle is on a non-priority road, enhancing safety without causing unnecessary stops.

Technical Background

Collision avoidance systems have been developed to prevent accidents at intersections by automatically stopping vehicles when a collision risk is identified. Traditional systems often delay braking until it is too late, particularly when the vehicle is on a priority road, leading to ineffective collision prevention. This device addresses these shortcomings by allowing for more proactive braking actions in critical situations.

Functionality of the Device

• The device includes a surrounding information acquisition unit that gathers data about nearby vehicles.
• An electronic control unit processes this data to determine the likelihood of a collision.
• If a risk is identified, the system assesses whether automatic braking should be initiated based on specific criteria.

Adjustments Based on Road Priority

The innovation lies in its ability to relax predetermined conditions for triggering automatic braking when the vehicle is on a non-priority road. This means that in such scenarios, the system can act more swiftly to prevent collisions, thereby reducing the risk of accidents. Conversely, if the vehicle is on a priority road, the system maintains stricter criteria to avoid unnecessary stops.

Additional Features and Benefits

The device also includes mechanisms for adjusting collision mode ranges and permission determinations for braking. By expanding these parameters when on non-priority roads, the system can more readily identify collision risks and initiate braking sooner. This dual approach ensures timely responses in high-risk situations while minimizing unnecessary interruptions in traffic flow.
