Vehicle Safety System Evasive Maneuver Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rear-end collisions can occur when a vehicle is stopped or moving slowly in traffic jams or unfavorable visibility conditions, posing a risk of accidents with fatal consequences, as other vehicles may approach at higher speeds without sufficient time to react.
Innovation Solution
A safety system for vehicles that includes a control system with processors, sensors, and communication devices to detect approaching vehicles and perform evasive maneuvers to reduce collision risk, using data from cameras, LIDAR, and radar sensors to determine the severity of the situation and provide control instructions for steering or acceleration to avoid collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle is stopped or moving slowly in traffic jams or unfavorable visibility conditions, then the vehicle can maintain position or reduce speed to avoid collisions, but this reduces productivity and increases loss of time
Solution Approach 1:
The safety system performs preliminary detection of approaching vehicles and calculates collision risk before a collision actually occurs. The system proactively determines evasive maneuvers in advance, allowing the vehicle to react preemptively to potential hazards rather than waiting for the situation to become critical.
Solution Approach 2:
The system continuously monitors the environment using sensors (cameras, LIDAR, radar) and provides real-time feedback about approaching vehicles and collision risks. This feedback loop enables dynamic adjustment of vehicle behavior based on current conditions, balancing safety requirements with throughput considerations.
2Reliability
If the safety system performs evasive maneuvers to avoid rear-end collisions, then collision risk is reduced, but the device complexity increases due to multiple sensors and control systems
Solution Approach 1:
The patent combines multiple sensing technologies (cameras, LIDAR, radar) and control functions into an integrated safety system. By merging these components and their data processing functions, the system achieves comprehensive collision avoidance capability while managing complexity through unified architecture rather than separate independent systems.
Solution Approach 2:
The safety system is designed to perform multiple functions: detecting approaching vehicles, calculating collision risk, determining evasive maneuvers, and controlling vehicle responses. This multi-functional approach consolidates what could be separate systems into a single universal safety platform, reducing overall system complexity.
3Loss of information
If the vehicle provides detailed collision risk information to approaching vehicles, then communication effectiveness improves, but loss of information increases due to potential communication failures or delays
Solution Approach 1:
The system transmits collision risk information to approaching vehicles in advance of potential collision. By providing this information preliminarily through V2V communication, the system allows other vehicles to prepare appropriate responses before the situation becomes critical, reducing the need for last-minute communications under stress.

AI summary
A safety system for a vehicle may include a processor configured to determine whether a further vehicle is approaching the vehicle from a backside or a lateral side; determine that a collision of the further vehicle with the vehicle is likely; determine an evasive maneuver of the vehicle such that the evasive maneuver reduces the collision likelihood or impact between the vehicle and the further vehicle; and provide control instructions to control the vehicle to perform the evasive maneuver.
