Vehicle Lane-Change Steering Control Without High-Accuracy Positioning

The patent replaces expensive high-accuracy locating systems with cheaper, more common sensors (accelerometers, gyroscopes, odometers) that are already present in most vehicles. These standard sensors are used in combination with a specifically designed controller to achieve lane-changing control without requiring costly specialized locating equipment.

The patent creates a virtual model of the vehicle's motion state by processing data from standard sensors through the controller. Instead of directly using high-accuracy locating data, the system copies the necessary position and orientation information by calculating it from accelerometer, gyroscope, and odometer data, achieving similar control functionality with cheaper components.

The patent pre-calculates and stores motion parameter relationships in the controller during system setup or calibration phases. By preparing lookup tables or pre-computed parameters beforehand, the system reduces the need for complex real-time calculations during actual lane-changing operations, thereby lowering continuous resource consumption while maintaining control precision.

The patent implements adaptive calculation frequency based on vehicle state. The controller adjusts the frequency of position calculations dynamically - performing more frequent calculations when the vehicle is in critical lane-changing phases and reducing frequency during stable states. This dynamic approach maintains necessary control precision while optimizing resource usage by avoiding unnecessary frequent calculations during steady conditions.
