Solution Overview
Problem
Existing vehicle remote start systems require manual configuration and identification of ignition switch wires, which is prone to human error and increases installation time due to the complexity of accessing and correctly matching the wires.
Innovation Solution
A remote start system with a controller that learns the mapping of remote start wires to ignition switch wires by sensing voltage sequences during a learning mode, allowing for arbitrary connection and reducing installation time and errors by simulating the ignition switch sequence for remote starting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration and identification of ignition switch wires is used, then the remote start system can be installed, but installation time increases and human error occurs
Solution Approach 1:
The remote start control module automatically identifies and maps ignition switch wires by sensing voltage sequences during ignition switch operation, eliminating the need for manual wire identification and configuration by the installer
Solution Approach 2:
The system performs automatic wire mapping and configuration during a preliminary learning mode operation, storing the identified wire sequences for future remote start operations, so that installation is completed before normal use begins
2Ease of operation
If manual identification of ignition switch wires is required, then the remote start system can function, but the installation complexity increases
Solution Approach 1:
The system replaces manual mechanical wire identification and matching with an automated electronic sensing and mapping process that detects voltage sequences on ignition switch wires and automatically configures the remote start control module
Solution Approach 2:
The controller acts as an intermediary that senses voltage on ignition switch wires and automatically maps them to remote start wires, eliminating the need for the installer to directly identify and match individual wires

AI summary
A remote start system is for a vehicle including an ignition switch sequentially movable to a plurality of switch positions, and a plurality of ignition switch wires coupled to the ignition switch. The remote start system may include a wiring harness having a plurality of remote start wires to be arbitrarily coupled to the plurality of ignition wires, a wireless receiver responsive to a wireless remote start signal, and a controller coupled to the wiring harness and the wireless receiver. The controller may, in a learning mode, perform a mapping of the remote start wires to the ignition wires based upon sequential movement of the ignition switch to the plurality of switch positions. The controller may, in an operating mode, selectively activate the remote start wires based upon the mapping to remote start an engine of the vehicle responsive to the wireless receiver.
