Dynamic Danger Range Calculation for Vehicle Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional advanced driver assistance systems (ADAS) primarily focus on physical collisions, failing to address driver uneasiness about surrounding objects, which hinders stable vehicle driving reliability.
Innovation Solution
A vehicle system equipped with first and second sensor devices to obtain driving and surrounding data, a controller processes this data to calculate danger ranges for both the vehicle and objects, predicting potential collision paths and controlling the vehicle to avoid overlaps, thereby addressing driver uneasiness and enhancing driving stability.

If the danger range is expanded to cover more area, then driver uneasiness is reduced, but the complexity of the system increases
Solution Approach 1:
The danger range is made dynamic rather than static. The system continuously adjusts the danger range based on real-time vehicle state (speed, acceleration, gear) and environmental factors (object type, position, movement). This dynamic adjustment allows the system to expand the danger range when needed to reduce driver uneasiness while contracting it when not necessary, thereby managing system complexity through adaptive behavior rather than fixed over-engineering.

AI summary
A vehicle includes a controller that identifies a target around the vehicle and calculates a danger range of the identified target, based on processing surrounding data obtained by sensor devices; calculates a danger range of the vehicle based on processing driving data obtained by sensor devices; determines a danger of collision based on the danger range of the target and the danger range of the vehicle, and control a driving apparatus based on the determined danger of collision. Such a vehicle and a control method thereof can make it possible to avoid a collision based on a danger range by calculating the danger range between the vehicle and a surrounding object of the vehicle depending on a factor causing uneasiness of a user.
