Vehicle Hazard Warning System for Delivery Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delivery vehicle operators face hazards such as passing traffic, slippery surfaces, and potholes during the last 100 meters of delivery, which are often unnoticed due to poor lighting, leading to potential safety risks and increased workload.
Innovation Solution
A system integrated into delivery vehicles uses sensors and lighting to detect hazards and provide warnings to operators, utilizing existing control modules and minimal hardware modifications, including radar, ultrasonic sensors, cameras, and LED lighting to alert operators of imminent dangers and guide them safely around the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If delivery operators manually monitor their surroundings during the last 100 meters, then they can detect hazards, but their workload increases and safety is compromised due to human limitations in poor lighting conditions
Solution Approach 1:
The system enables the vehicle to autonomously monitor its surroundings for hazards without requiring the operator to manually scan the environment. Sensors mounted on the vehicle independently detect obstacles, pedestrians, and environmental conditions, then provide warnings to the operator, allowing the vehicle to serve its own safety monitoring function.
Solution Approach 2:
The patent replaces the mechanical human visual inspection system with electronic sensor-based detection. Instead of relying on the operator's eyes and brain to process visual information in poor lighting, the system uses cameras, LIDAR, and other sensors that can detect hazards in conditions invisible to the human eye, then presents this information to the operator.
2Productivity
If driver assistance technology is used during driving, then efficiency is improved, but safety during the last 100 meters when the vehicle is stopped remains limited
Solution Approach 1:
The system dynamically adjusts its monitoring and warning behavior based on the vehicle's operational state. When the vehicle is moving, it provides standard driver assistance. When the vehicle stops for delivery and the operator exits, the system transitions to monitoring the operator's safety in the perimeter zone, continuously adjusting warnings based on the operator's position and detected hazards.
Solution Approach 2:
The system serves multiple functions: it acts as a driver assistance system during transit, transitions to an operator safety monitoring system during delivery operations, and provides environmental awareness in both states. The same sensor suite and processing architecture support both driving safety and delivery operation safety, eliminating the need for separate specialized systems.
3Reliability
If comprehensive hazard monitoring is implemented, then operator safety is improved, but system complexity and cost increase
Solution Approach 1:
The patent combines multiple sensor types (cameras, LIDAR, ultrasonic sensors) and integrates them with the vehicle's existing control modules and communication systems. By merging these functions into a unified hazard monitoring and warning system, the architecture avoids duplication and leverages shared processing and powertrain control infrastructure.
Solution Approach 2:
The system introduces a hazard monitoring controller as an intermediary between the sensors and the operator. This controller processes data from multiple sensor sources, determines hazard levels, and generates appropriate warnings, simplifying the overall system architecture by centralizing the decision-making logic rather than requiring direct complex interactions between all components.

Data Source
AI summary
Systems and methods for administering a hazard condition warning during a package delivery operation are provided. The system includes one or more sensors, e.g., radar sensors or cameras, configured to detect a hazard condition in a vicinity of a delivery vehicle and to generate data indicative of the hazard condition. The system further includes an operator sensor configured to detect a location of an operator relative to the delivery vehicle and one or more indicators, e.g., lights, a mobile application installed on a mobile phone, or an HMI of the vehicle, configured to generate an alert corresponding to the hazard condition. A processor of the system may determine whether the hazard condition is present based on the data indicative of the hazard condition, and cause, based on a presence of the hazard condition and the detected location of the operator, the one or more indicators to generate the alert.
