Autonomous Lane Change Control Across Solid Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous driving technologies lack flexibility in adapting to various traffic scenarios, particularly in situations requiring lane changes across solid lines, which limits their capability in emergency avoidance and personalized driver intentions.
Innovation Solution
A vehicle control method and apparatus that includes a cross-solid-line lane change permission switch, allowing the vehicle to change lanes when enabled by the driver's operation and adjusted road condition parameters, while providing prompts to ensure safe lane changes and respecting driver intentions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous driving technology strictly follows traffic rules to forbid crossing solid lines, then safety and rule compliance are improved, but flexibility in emergency avoidance and adapting to diverse traffic scenarios deteriorates
Solution Approach 1:
The patent applies the dynamics principle by introducing a cross-solid-line lane change permission switch that dynamically adjusts the vehicle's lane changing behavior. When the switch is enabled, the vehicle can cross solid lines despite traffic rules; when disabled, it strictly follows rules. This dynamic configuration allows the system to adapt between safety compliance and emergency flexibility based on driver intent and situational needs.
Solution Approach 2:
The patent utilizes parameter changes by modifying the lane changing permission parameter through the cross-solid-line lane change permission switch. By changing this parameter from a fixed state to a configurable state, the system can adjust its behavior to either strictly follow traffic rules or allow emergency lane changes across solid lines, thereby resolving the contradiction between rule compliance and emergency adaptability.
2Extent of automation
If autonomous driving technology mechanically follows traffic rules without driver intervention, then automation level is improved, but driver intention recognition and personalized requirements deteriorate
Solution Approach 1:
The patent applies the feedback principle by incorporating driver operations (such as turn signal switch operations) as feedback inputs to the autonomous driving control system. The system monitors driver actions and uses them to trigger lane change operations, creating a feedback loop that allows driver intentions to influence automated decision-making. This resolves the contradiction by maintaining high automation while incorporating driver intent recognition.
Solution Approach 2:
The patent utilizes self-service by enabling the autonomous driving system to automatically execute lane changes based on detected driver operations without requiring explicit continuous commands. Once a driver operation is detected, the system autonomously determines and executes the lane change maneuver, combining automated execution with driver-initiated intent detection.
3Adaptability or versatility
If autonomous driving technology allows cross-solid-line lane changes, then flexibility and emergency avoidance capability are improved, but traffic rule compliance and potential safety risks deteriorate
Solution Approach 1:
The patent applies preliminary action by requiring the driver to explicitly enable the cross-solid-line lane change permission switch before the vehicle can cross solid lines. This preliminary configuration action ensures that the system and driver have pre-agreed on the permission status, maintaining traffic rule compliance by default while allowing flexibility when explicitly authorized. The switch state serves as a preliminary condition that must be satisfied before emergency lane changes can occur.

AI summary
A vehicle control method and apparatus 10, and a vehicle 100 are provided. The vehicle 100 has a cross-solid-line lane change permission switch 16. When the cross-solid-line lane change permission switch 16 is in an on state, and a driver switches a turn signal switch to a state that a left turn signal or a right turn signal is on, the vehicle 100 can cross a solid line to change a lane.
