Turn Signal Lane Change Control for Single-Action Multi-Lane Shifts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems require occupants to repeatedly operate the turn signal lever for lane change assistance control over multiple lanes, which is inconvenient and inefficient.
Innovation Solution
A vehicle control system that executes first and second lane change assistance controls based on distinct operations of the turn signal lever, allowing a single operation to initiate lane changes to adjacent and distant lanes, respectively, without further occupant input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle executes lane change assistance control over multiple lanes using a single operation member operation, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent segments the lane change assistance control into two distinct control modes: first lane change assistance control for adjacent lanes and second lane change assistance control for distant lanes. The processor identifies the number of lanes to be changed based on the operation member operation state and executes different control algorithms accordingly, allowing single operation to achieve multi-lane changes while maintaining manageable system complexity through modular control logic
Solution Approach 2:
The operation member is designed to serve multiple functions: it can initiate both first lane change assistance control for adjacent lanes and second lane change assistance control for distant lanes based on the same physical operation. The system universally handles different lane change scenarios through a single operation interface, eliminating the need for separate controls for different lane change distances
2Device complexity
If the vehicle requires repeated operation member operations for multi-lane changes, then the device complexity is reduced, but the loss of time increases
Solution Approach 1:
The system performs preliminary identification of the target lane based on the initial operation member operation state before executing the lane change sequence. The processor determines the number of lanes to be changed in advance and pre-plans the lane change path, allowing the vehicle to execute continuous multi-lane changes without requiring intermediate operations, thereby reducing the time loss associated with repeated operations

AI summary
A vehicle control device includes a processor which, when an operation member operable by an occupant of a vehicle has been operated, causes the vehicle to execute lane change assistance control, wherein the processor: executes first lane change assistance control that moves the vehicle from a travel lane, which is a lane in which the vehicle is traveling, to an adjacent lane when a first operation has been executed with respect to the operation member; and executes second lane change assistance control that moves the vehicle from the travel lane to a distant lane, which is a lane on the opposite side of the travel lane across the adjacent lane, when a second operation different from the first operation has been executed with respect to the operation member.
