Vehicle Driving Support Control with Unified Switch Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving support systems for vehicles are complex and require multiple switches for different control functions, making it difficult for drivers to navigate and leading to inefficiencies in functional unification.
Innovation Solution
A driving support device with multiple first control units and second control units, where the first control units perform high-level driving support (e.g., follow-up travel and lane keeping) and the second control units perform lower-level support (e.g., deceleration and steering) with separate switches for each level, allowing for efficient functional unification by reducing the number of switches needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated switches are provided for each driving support control function, then each control can be independently activated, but the number of switches increases making operations difficult for drivers
Solution Approach 1:
The patent merges multiple driving support control functions (follow-up travel control, lane keeping control, deceleration control, steering control) into a unified control system that can be activated by a single switch operation. The control execution unit integrates these functions and activates them collectively based on one switch input, reducing the number of switches while maintaining independent controllability of each function through the unified system.
Solution Approach 2:
The control execution unit is designed with multi-functionality to handle various driving support controls through a single switch. This universal control mechanism can activate multiple control functions (longitudinal and lateral controls) simultaneously or selectively, making one switch perform the work of multiple dedicated switches while preserving functional independence.
2Ease of operation
If the number of switches is reduced through functional unification, then driver operations are simplified, but control precision and reliability may be compromised
Solution Approach 1:
The patent segments the control system into distinct control units (follow-up travel control unit, lane keeping control unit, deceleration control unit, steering control unit) that maintain their functional independence. Each unit processes specific control functions separately, ensuring reliable and precise control execution even though they are activated through a unified switch mechanism. This segmentation preserves control precision while enabling operational simplification.
Solution Approach 2:
The control execution unit acts as an intermediary between the single switch and multiple control functions. It receives the switch input and reliably distributes activation signals to the appropriate control units, ensuring that control precision and reliability are maintained through proper signal management and coordination among the segmented control functions.

AI summary
A driving support device mounted on a vehicle includes a plurality of first control units, and a plurality of second control units of which a support level is lower than that of the plurality of first control units, and the plurality of the first control units start when a first switch is operated, and the plurality of second control units start when a second switch different from the first switch is operated.
