Camera Mirror Wiring Harness CAN Bus Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for accessing and connecting to vehicle CAN bus data in vehicles are often expensive, inconvenient, and risk damage to the vehicle's harness or connectors, particularly in aftermarket installations where additional connections are not readily available.
Innovation Solution
A simplified wiring harness system with a pigtail of two wires, connected between a CAN bus and a driver information system, using an adapter with a printed circuit board for pin-to-pin connection, allowing easy and reliable access to vehicle parameter data without active components or additional power, thus avoiding complexity and risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods are used to access and connect to vehicle CAN bus data, then data transmission can be achieved, but the installation becomes complex and risks damage to vehicle harness or connectors
Solution Approach 1:
The patent introduces a wiring harness with a pigtail as an intermediary component that connects the camera mirror system to the CAN bus and driver information system. This pigtail with pre-attached connectors serves as a mediator that simplifies the installation process by eliminating the need for complex custom wiring while maintaining reliable electrical connections for data transmission
Solution Approach 2:
The wiring harness is pre-assembled with connectors attached to the pigtail wires before installation in the vehicle. This preliminary preparation of connections allows for quick and easy installation without requiring on-site wiring work, reducing the risk of damage to vehicle harnesses and connectors while ensuring proper connection reliability
2Adaptability or versatility
If additional connections are made to access CAN bus data, then data access is achieved, but the risk of damage to vehicle harness or connectors increases
Solution Approach 1:
The wiring harness acts as an intermediary that provides a safe and standardized interface between the camera mirror system and the vehicle's CAN bus. By using pre-fabricated connectors and a dedicated pigtail, the system accesses CAN bus data without requiring modifications or additional connections to the vehicle's existing harness, thereby eliminating the risk of damage
Solution Approach 2:
The wiring harness with pigtail is designed as a standalone, replaceable component that can be easily installed and removed without affecting the vehicle's permanent wiring. This disposable-like approach allows for easy installation and replacement if needed, protecting the vehicle's original harness from damage while providing the necessary data access capability
Data Source
AI summary
A vehicle camera mirror system includes a CAN bus that carries vehicle parameter data having vehicle speed, steering angle, braking and/or engine RPM. A driver information system (DIS) graphically displays the vehicle parameter data to a driver, and a camera mirror system includes a camera which has a field of view at least one of Class II and Class IV views. A display is in communication with the camera and is configured to display the field of view, and a controller is in communication with the camera and the display. A wiring harness has first and second connectors that are respectively connected to the CAN bus and the DIS. The wiring harness includes a pigtail that has first and second wires that are electrically connected between the first and second connectors. The first and second wires are connected to the controller to provide the vehicle parameter data.
