Vehicle Driving Assistance Using Free-Space Collision Avoidance
Solution Overview
Problem
Existing vehicle assistance systems fail to effectively avoid collisions when driving too fast, as emergency braking may not be sufficient to prevent accidents.
Innovation Solution
A vehicle assistance system that includes sensors and cameras to detect objects and free spaces, an electronic control unit to select a free space, and light-emitting devices to illuminate the selected space, providing a new path for the vehicle to follow.

Engineering Contradiction Analysis
1Reliability
If emergency braking system is activated to avoid collision, then collision avoidance capability is improved, but at high speeds the braking distance becomes too long and collision cannot be avoided
Solution Approach 1:
Instead of only braking to avoid collision, the system inverts the approach by steering the vehicle into a free space adjacent to the detected object, effectively changing from a stopping-based avoidance strategy to a path-deviation-based strategy. This allows avoidance even when braking distance is insufficient at high speeds.
Solution Approach 2:
The system performs preliminary detection of free spaces adjacent to detected objects before collision occurs. By identifying available maneuvering space in advance and preparing the steering intervention, the system can execute avoidance maneuvers more quickly and effectively when collision risk arises.
2Device complexity
If the system only uses warning and emergency braking, then the system complexity is kept simple, but the effectiveness of collision avoidance is insufficient at high speeds
Solution Approach 1:
The system merges sensor detection capabilities with autonomous steering control to create a integrated avoidance system. By combining the existing sensor-camera-object detection infrastructure with steering intervention and free space detection, the system achieves enhanced collision avoidance without requiring completely new subsystems.
Solution Approach 2:
The sensor system serves multiple functions: detecting objects on the collision path, identifying free spaces adjacent to objects, and providing data for both warning/breaking and steering avoidance modes. This multi-functionality allows the system to handle various scenarios with a unified detection platform.

AI summary
The invention relates to a system for assisting with driving a vehicle, including at least one sensor configured to detect the presence of an object in an environment outside the vehicle, at least one camera configured to acquire images of the environment outside the vehicle and to detect the presence of the object in the environment outside the vehicle. The at least one sensor detects at least one free space in the environment outside the vehicle, the at least one camera, on the basis of the acquired images, detects at least one free space. An electronic control unit configured to select a free space found by the at least one sensor and/or the at least one camera, the electronic control unit activates the display of images in the selected free space so as to indicate a new path to be followed by the vehicle.
