VEHICLE DETECTION SYSTEM AND METHOD FOR DETECTING A TARGET VEHICLE IN A DETECTION AREA LOCATED BEHIND A SUBJECT VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18483667 titled 'VEHICLE DETECTION SYSTEM AND METHOD FOR DETECTING A TARGET VEHICLE IN A DETECTION AREA LOCATED BEHIND A SUBJECT VEHICLE

Simplified Explanation

The patent application describes a vehicle detection system that can determine if a target vehicle approaching from behind in the same driving lane as the subject vehicle is an alert object. The system then alerts the driver of the subject vehicle of the presence of the target vehicle based on this determination. Additionally, the system calculates an overlap change rate by analyzing the lateral overlap of the target vehicle in the detection area over a specified time period.

• Vehicle detection system for determining if a target vehicle is an alert object
• Alerts the driver of the subject vehicle of the presence of the target vehicle
• Calculates overlap change rate based on lateral overlap of the target vehicle

Potential Applications

This technology can be applied in advanced driver assistance systems (ADAS) to enhance vehicle safety by providing early warnings to drivers about the presence of vehicles approaching from behind in the same lane.

Problems Solved

1. Improves driver awareness of surrounding vehicles 2. Helps prevent collisions by alerting drivers of potential hazards

Benefits

1. Increased safety on the road 2. Enhanced driver assistance features 3. Potential reduction in rear-end collisions

Potential Commercial Applications

Enhanced safety features for automotive manufacturers Improved driver assistance systems for fleet management companies

Possible Prior Art

One possible prior art could be the use of rearview cameras and sensors in vehicles to detect objects in blind spots and provide warnings to drivers. However, the specific method of calculating the overlap change rate as described in this patent application may be a novel innovation.

Unanswered Questions

How does the system differentiate between different types of alert objects?

The patent application does not provide details on how the system distinguishes between various types of alert objects apart from target vehicles.

What is the accuracy rate of the system in detecting target vehicles?

The application does not mention the accuracy rate of the system in detecting target vehicles approaching from behind.

Original Abstract Submitted

A vehicle detection system configured to judge whether a target vehicle, which has been detected to approach the subject vehicle from behind in a driving lane being used by the subject vehicle and being covered by the detection area is an alert object, to output a result of judgement to a warning which warns a driver of the subject vehicle that a target vehicle () is present in the driving lane behind the subject vehicle based on the judging the target vehicle to be an alert object, and to determine, on the basis of a change of a lateral overlap of the target vehicle in the detection area, an overlap change rate which is defined as a ratio of the change of the overlap to a specified time.
