Vehicle Control for Safe Driving Assistance Invalidation Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in preventing the immediate invalidation of driving assistance functions during vehicle travel when update information is received from the server, which can be undesirable, especially in sustainable transportation systems.
Innovation Solution
A vehicle control device equipped with a communication unit, a controller, and sensors that detect the traveling state of the vehicle, which prohibits the invalidation of validated vehicle functions when update information is received from the server while the vehicle is in transit, ensuring the function remains active until the vehicle has stopped.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If update information is received from the server to invalidate the vehicle function, then the function management is updated according to the trial period, but the vehicle function is immediately invalidated during traveling which is not preferable
Solution Approach 1:
The controller applies preliminary anti-action by detecting the traveling state before invalidating the vehicle function. When the sensor detects that the vehicle is traveling, the controller prohibits invalidation of the validated vehicle function even if update information is received. This preventive measure ensures that the driving assistance function remains active during traveling, preventing safety issues before they can occur.
2Device complexity
If the vehicle function is invalidated immediately upon receiving update information, then the server management is simplified, but the driving assistance function may be disabled during travel causing safety issues
Solution Approach 1:
The controller performs preliminary action by checking the traveling state before executing the invalidation process. The sensor continuously monitors whether the vehicle is traveling, and this information is used by the controller to determine whether to prohibit invalidation. This preliminary check ensures that the function remains active during travel while still allowing invalidation when appropriate (when the vehicle is not traveling), thus maintaining safety without excessive complexity.

AI summary
A vehicle control device having a driving assistance function, includes: a communication unit configured to communicate with a server; a controller configured to control the vehicle based on a validated vehicle function; and a sensor configured to detect a traveling state of the vehicle. When the communication unit receives update information for invalidating the vehicle function from the server while the vehicle is traveling, the controller prohibits invalidation of the validated vehicle function.
