Auxiliary Vehicle Control from Start Actuation and Driver State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transportation vehicle systems require manual activation and control of auxiliary systems after the propulsion motor is started, which can distract the operator and hinder efficient preparation for the vehicle's mission.
Innovation Solution
A computer-implemented method using processing circuitry to determine manual actuation of the start actuator, driver seat occupancy, and driver side door state to control auxiliary systems based on predetermined rules, allowing for automated activation of temperature control, lighting, and other systems without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control of auxiliary systems is implemented, then the operator can control each system individually, but the operator's attention is distracted and preparation time increases
Solution Approach 1:
The system performs preliminary actions by automatically activating auxiliary systems (lighting, climate control, windows) based on detected door opening events and environmental conditions, eliminating the need for manual operation and reducing preparation time before vehicle departure
Solution Approach 2:
The auxiliary systems serve themselves through automated control logic that monitors sensor inputs (door state, ambient temperature, light levels) and autonomously activates or deactivates systems without requiring operator intervention
2Productivity
If automated auxiliary system control is implemented, then preparation time is reduced and operator support is improved, but system complexity increases
Solution Approach 1:
The control system achieves multi-functionality by using a single automated control unit that manages multiple auxiliary systems (lighting, climate control, window operation) through unified logic, reducing the need for separate control mechanisms for each system
Solution Approach 2:
The control system acts as an intermediary between sensor inputs (door state, temperature sensors, light sensors) and auxiliary system actuators, coordinating their interactions through centralized logic that simplifies the overall system architecture
3Ease of operation
If auxiliary systems are activated based on environmental conditions, then operator comfort is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts auxiliary system operation based on real-time environmental conditions and vehicle state, activating systems only when necessary (e.g., climate control when door is opened and temperature threshold is exceeded, lighting only in dark conditions) and deactivating them when conditions change, thereby optimizing energy consumption while maintaining comfort
