Vehicle Remote Start Exhaust Control with Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote start systems for vehicles lack the ability to adapt exhaust control based on the vehicle's surroundings, particularly when started remotely, which can lead to unexpected noise or emissions when users are unaware of the immediate situation.
Innovation Solution
A vehicle computing system that utilizes sensors and processors to detect the presence of animals or people within a predefined distance from the exhaust and adapts the remote start process by delaying or modifying the exhaust profile based on predefined predicates, including user-configurable zones and geo-fencing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote start is enabled without environmental sensing, then remote start functionality is achieved, but noise and emissions may affect unaware users or pedestrians
Solution Approach 1:
The system uses the vehicle's existing sensors (ultrasonic, infrared, cameras, microphones) to autonomously detect the presence of users or pedestrians and automatically adjust exhaust control, eliminating the need for separate dedicated sensing systems
Solution Approach 2:
The system makes existing multi-purpose sensors serve an additional function by using them for both their original purposes and for detecting user presence to control exhaust, thereby avoiding added system complexity
2Object-affected harmful factors
If sensors are used to detect user presence, then noise and emissions can be minimized, but system complexity increases
Solution Approach 1:
The vehicle's existing sensor suite performs dual functions by detecting both environmental conditions for their original purposes and for user presence detection to control exhaust, eliminating the need for separate dedicated sensing systems
Solution Approach 2:
The system makes existing multi-purpose sensors serve an additional function by using them for both their original purposes and for detecting user presence to control exhaust, thereby avoiding added system complexity
3Speed
If remote start command is executed immediately, then response time is fast, but safety risks exist when users are unaware of vehicle surroundings
Solution Approach 1:
The system performs preliminary sensing of the environment for user presence before executing the remote start command, using detected information to determine whether to allow immediate startup or delay/modify the command to ensure safety
Solution Approach 2:
The system uses sensor feedback about user presence to dynamically adjust the remote start execution, providing a safety check that modifies or delays startup when users or pedestrians are detected in hazardous positions

AI summary
A vehicle includes receives a remote start request from a user, responsive to the request, engage at least one vehicle sensor to determine whether at least an animal or person are within at least a predefined distance from an exhaust or external sounder of the vehicle. Additionally, the vehicle, responsive to determining that the animal or person are withing the predefined distance, delays execution of a remote start, requested by the request, for at least a predefined period of time.
