School Bus Cruise Control System for Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Despite regulations, accidents involving vehicles colliding with children and preschoolers getting on or off school buses often occur due to drivers failing to stop or slow down appropriately, as they are unaware of or neglect the school bus cruise regulations.
Innovation Solution
A method and apparatus for cruise control that utilizes an advanced driver assistance system (ADAS) or autonomous system to monitor the school bus and road environment, determining whether a vehicle should stop based on predefined regulations, and either guiding the driver or automatically controlling the vehicle to stop when a school bus is ahead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drivers continue to cruise by passing the school bus while maintaining driving past even though the school bus is stopped, then the driving efficiency is improved, but the safety deteriorates as drivers do not see children who suddenly run out from ahead of the school bus
Solution Approach 1:
The system performs preliminary detection of the school bus stopped state and road environment conditions before the vehicle reaches the bus. It proactively determines whether stopping is required based on predefined regulations, and prepares the braking system in advance, allowing the vehicle to stop safely without sudden emergency braking while maintaining driving efficiency.
Solution Approach 2:
The system continuously monitors the school bus position, road environment, and vehicle state, and provides real-time feedback to the driver through display devices or automatic control. This feedback loop ensures the driver is aware of the stopping requirement and the vehicle automatically adjusts its behavior to comply with safety regulations.
2Object-affected harmful factors
If the advanced driver assistance system or autonomous system is introduced to detect and respond to school bus stop conditions, then the safety is improved, but the device complexity increases
Solution Approach 1:
The system utilizes existing multi-functional sensors and processors in modern vehicles for school bus detection, road environment monitoring, and collision avoidance. By making these existing components serve multiple purposes including school bus regulation compliance, the system improves safety without significantly increasing device complexity.
Solution Approach 2:
The system automatically detects school bus stop conditions, determines stopping requirements based on predefined regulations, and executes braking control without requiring additional dedicated hardware. The vehicle's existing autonomous driving infrastructure serves the school bus safety function, minimizing complexity increase.
3Reliability
If the vehicle automatically stops when a school bus is stopped ahead, then the compliance with traffic regulations is improved, but the loss of time increases due to waiting
Solution Approach 1:
The system dynamically adjusts the stopping behavior based on real-time road environment conditions. When the road is clear of obstacles and safe to pass, the system allows the vehicle to maintain cruise or pass the school bus. When obstacles are detected or conditions require stopping, the system enforces stopping. This dynamic adaptation ensures regulation compliance while minimizing unnecessary waiting time.
Data Source
AI summary
Method and apparatus for a vehicle cruise control, particularly concerning a school bus, which includes collecting information on the school bus and a road environment positioned around nearby vehicle, monitoring position, velocity and moving direction of the school bus, and state of surrounding road. If the school bus is stopped relatively near the front of the nearby vehicle, the method continues by determining whether or not the vehicle is stopped by comparing the collected school bus information and the road environment information with a predefined cruise regulation based on the school bus, and guiding the driver to stop as well as controlling the vehicle to stop depending on the determination result.
