Vehicle Accessory Control System Using Mode Switching Actuator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and cost of vehicle accessory controls increase with the addition of multiple accessories, making them less convenient to access and operate, particularly in vehicles designed for off-road or utility purposes.
Innovation Solution
A control system with a paddle shifter and selector that allows operators to switch between powertrain and accessory modes using actuators, enabling convenient operation of vehicle features like winches, headlights, and audio devices without additional parts, reducing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple accessories are added to enhance vehicle functionality, then vehicle versatility is improved, but device complexity and cost increase
Solution Approach 1:
The actuator is designed to perform multiple functions by switching between powertrain mode and accessory mode. A single actuator controls both powertrain components (transmission, differential lock) and accessories (winch, headlights, audio system), eliminating the need for separate controls for each accessory and reducing overall system complexity.
2Adaptability or versatility
If multiple accessory controls are added to operate additional accessories, then vehicle versatility is improved, but ease of operation deteriorates
Solution Approach 1:
The control for accessories is merged with the existing paddle shifter controls adjacent to the steering wheel. The same actuators used for powertrain control are also used for accessory control, consolidating multiple control functions into a single accessible location that the operator can reach while steering.
3Adaptability or versatility
If separate control systems are provided for each accessory, then accessory functionality is improved, but device complexity and cost increase
Solution Approach 1:
The actuator serves as a universal control device that can operate different accessories based on the selected mode. The system uses one actuator with mode switching capability rather than multiple dedicated actuators, reducing the number of parts while maintaining full accessory functionality.

AI summary
A control system for a vehicle, such as an off-road recreational vehicle, that includes a powertrain and an accessory. The control system includes an actuator, such as a paddle shifter, configured to operate in a powertrain mode to control an aspect of the powertrain, and to operate in an accessory mode to control an aspect of the accessory. The control system also includes a selector configured to switch the actuator between the powertrain mode and the accessory mode.
