Vehicle Avoidance Control Using Heading and Lateral Position

The system changes the parameters used for collision assessment from only physical distance and relative speed to include multiple additional parameters: heading angle, lateral position, amount of turning, and change amount of heading angle. This multi-parameter approach allows the system to distinguish between actual collision risks and normal driving scenarios, reducing false positives while maintaining reliable collision detection

The controller acts as an intermediary that processes multiple sensor inputs (object data and motion data) and evaluates them against predetermined threshold values before triggering avoidance control. This intermediary evaluation layer prevents direct overreaction to single parameters and enables more nuanced decision-making about when intervention is actually necessary

The system segments the collision assessment process into distinct evaluation stages: first determining heading angle from object data and motion data, then calculating lateral position,接着 determining amount of turning, and finally evaluating change amount of heading angle. Each parameter is independently calculated and compared against its own threshold, making the complex multi-parameter system manageable and systematic

The controller is designed to handle multiple functions: it processes object data from the sensing device, processes motion data from the sensor, calculates multiple geometric parameters, compares each against thresholds, and makes the final control decision. This multi-functional controller consolidates the complexity into a single processing unit rather than requiring separate systems for each function
