Solution Overview
Problem
Existing vehicle control systems face challenges in accurately setting risk potential and controlling vehicles based on the movement of surrounding objects, particularly when objects are rotating at high speeds, leading to potential interference with the host vehicle.
Innovation Solution
A vehicle control device and method that includes a recognizer to identify surrounding objects and a controller to manage speed and steering, setting risk areas based on object rotation speed and direction, restricting access to prevent interference by adjusting risk areas and controlling vehicle trajectory accordingly.

Engineering Contradiction Analysis
1Measurement precision
If the vehicle control system sets risk potential based on basic movement detection, then the control system is simple to implement, but it cannot accurately assess risk when moving objects rotate at high speeds
Solution Approach 1:
The system performs preliminary detection of rotation speed before final risk assessment. The rotation speed detection unit预先 detects whether the moving object is rotating at high speed, and this information is used to adjust the risk potential calculation in advance, ensuring accurate risk assessment before control decisions are made
Solution Approach 2:
The control system is divided into separate functional units: a rotation speed detection unit that specifically detects high-speed rotation, and a risk potential setting unit that uses this detection results to adjust risk assessment. This segmentation allows the system to handle complex rotation scenarios without requiring complete system redesign
2Reliability
If the vehicle maintains a standard safety distance from all moving objects, then collision risk is reduced, but the vehicle's productivity and efficiency decrease due to excessive caution
Solution Approach 1:
The risk potential setting unit applies different safety margins to different moving objects based on their local characteristics. Objects rotating at high speed with front surfaces facing the vehicle's path are assigned higher risk potentials and larger safety distances, while other objects use standard or reduced safety margins, optimizing both safety and efficiency
Solution Approach 2:
The system applies excessive caution (larger safety distance) only partially to specific high-risk scenarios where objects rotate at high speeds and face the vehicle's traveling direction. For all other scenarios, the system uses standard or minimal safety distances, maintaining productivity while ensuring safety where needed
3Reliability
If the vehicle control system monitors all moving objects continuously, then safety is maximized, but the information processing load and energy consumption increase
Solution Approach 1:
The rotation speed detection unit performs continuous monitoring only for objects that exhibit rotation characteristics, rather than continuously analyzing all detected objects. This partial monitoring approach reduces processing load and energy consumption while maintaining reliability for high-risk rotating objects
Solution Approach 2:
The system changes the monitoring parameter dynamically: for objects rotating at high speed, the system continuously tracks rotation speed and front surface orientation; for other objects, monitoring is performed at lower intensity or only when conditions change. This parameter adaptation optimizes energy usage while maintaining safety

AI summary
A vehicle control device includes a recognizer configured to recognize a surrounding environment of a vehicle including a moving object present around the vehicle and a controller configured to control at least one of a speed and steering of the vehicle. The controller restricts access to the moving object when the moving object is rotating around a vertical axis at a speed greater than or equal to a threshold value so that a front surface of the moving object recognized by the recognizer faces a position interfering with a position in a traveling direction of the vehicle as compared with when the moving object is not rotating.
