Vehicle Control With Driver-Authorized Solid-Line Lane Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous driving technologies lack flexibility in adapting to complex real-world traffic scenarios and do not allow vehicles to cross solid lines for lane changes, which can lead to accidents or inconvenience.
Innovation Solution
A vehicle control method and apparatus that enables lane changes by detecting a driver's operation and a cross-solid-line lane change permission switch, allowing the vehicle to cross solid lines when the switch is on, while providing prompts and adjusting road condition parameters to meet the driver's intentions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous driving technology strictly follows traffic rules and forbids crossing solid lines, then safety and rule compliance are improved, but flexibility in handling emergency situations deteriorates
Solution Approach 1:
The patent introduces a dynamic permission mechanism where the cross-solid-line lane change permission switch can be toggled between on and off states. When turned on, the vehicle is permitted to cross solid lines for lane changes; when off, the vehicle strictly follows traffic rules. This dynamic switching capability allows the autonomous driving system to adapt between strict rule compliance and emergency situation handling, resolving the contradiction between safety and flexibility.
2Extent of automation
If autonomous driving technology mechanically follows traffic rules without human intervention, then automation level is improved, but ability to handle complex real-world scenarios deteriorates
Solution Approach 1:
The patent introduces a cross-solid-line lane change permission switch as an intermediary mechanism between the autonomous driving system and traffic rules. This switch acts as a mediator that can be activated under specific conditions (such as emergency situations detected by the system or manual activation), allowing the autonomous vehicle to temporarily override the no-crossing-solid-line rule. This intermediary mechanism enables the system to maintain high automation while gaining the flexibility to handle complex real-world scenarios that require rule exceptions.
3Speed
If the vehicle allows cross-solid-line lane changes without driver permission, then responsiveness to emergency situations is improved, but driver control and safety deteriorates
Solution Approach 1:
The patent implements a preliminary permission mechanism where the driver or system must activate the cross-solid-line lane change permission switch before the vehicle can cross solid lines. This preliminary action ensures that driver control is maintained while still allowing responsive emergency handling. The switch activation serves as a pre-authorization that enables subsequent cross-solid-line lane changes without requiring real-time driver intervention, thus maintaining both responsiveness and driver control.

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.
