Vehicle Control Mismatch Detection for Automated Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic driving control systems face reliability issues due to mismatches between map information and detection information from on-board sensors, leading to potential collisions and reduced driver confidence, as existing systems do not account for discrepancies between the two sources of data.
Innovation Solution
A vehicle control apparatus equipped with a mismatch determiner and a control aspect changer that adjusts the automatic driving control in response to mismatches between map information and detection information, allowing for smoother transition to manual driving and improved collision avoidance.

Engineering Contradiction Analysis
1Extent of automation
If automatic driving control is performed using map information and detection information from sensors, then the vehicle can autonomously navigate along a travel path, but mismatches between map information and detection information reduce the reliability of the control system
Solution Approach 1:
The system continuously compares detection information from sensors with map information to identify mismatches, and uses this feedback to switch between automatic and manual driving modes. The mismatch determiner constantly monitors the consistency between map-based expected positions and sensor-based actual positions, providing feedback that triggers appropriate control mode changes.
Solution Approach 2:
The control system dynamically switches between automatic driving control and manual driving control based on the presence or absence of mismatches between map information and detection information. This dynamic adaptation allows the system to maintain high automation when conditions are reliable, while switching to manual control when reliability is compromised by mismatches.
2Reliability
If the system switches to manual driving upon detecting a mismatch, then driver control is restored, but the automation level and convenience of automatic driving is reduced
Solution Approach 1:
The system takes preliminary action by switching to manual driving control before a potential collision or hazardous situation can occur. By detecting mismatches between map information and sensor data in advance, the system proactively transitions to manual control mode, preventing situations where unreliable automatic control could lead to accidents.
Solution Approach 2:
The mismatch determiner acts as an intermediary that monitors the consistency between map information and detection information, and mediates the transition between automatic and manual driving modes. This intermediary component enables smooth switching between control modes based on the reliability of available information.
3Device complexity
If no measures are taken for mismatches between map information and detection information, then the system structure remains simple, but the vehicle cannot properly handle road condition changes or sensor failures
Solution Approach 1:
The system performs preliminary comparison and validation of map information against detection information before relying on automatic driving control. By预先 identifying mismatches between expected map-based positions and actual sensor-detected positions, the system can take preventive measures rather than reacting to failures after they occur.

AI summary
A vehicle control apparatus for performing automatic driving control of a vehicle carrying the apparatus based on a travel path to a destination, which path is set using map information, and detection information about surroundings of the vehicle detected by sensors mounted in the vehicle. In the vehicle control apparatus, a mismatch determiner is configured to, during automatic driving control, determine whether or not there is a match between the map information and the detection information acquired from the sensors. A control aspect changer is configured to, if it is determined by the mismatch determiner that there is a mismatch between the map information and the detection information, change a control aspect of automatic driving control in response to a situation of mismatch.
