  • Publication number: 20250209866
    Abstract: A vehicle control system includes a vehicle state estimator, a delay simulator and an error compensation optimizer. The vehicle state estimator is configured to generate an estimated future vehicle state at a future time point. The delay simulator is configured to determine a delay time based on the estimated future vehicle state and a current vehicle state, and obtain a delayed future vehicle state based on the delay time. The error compensation optimizer is configured to generate a driving parameter estimation compensation to the vehicle state estimator based on a difference between the delayed future vehicle state and a target vehicle state being outside the error range.

  • Patent number: 10718620
    Abstract: A navigation and positioning device including a storage, a mark feature analyzer, a first coordinate fusion component and a second coordinate fusion component is provided. The storage stores map information including a traffic mark feature and its mark coordinate. The mark feature analyzer is used for analyzing whether a captured image has the traffic mark feature. When the captured image has the traffic mark feature, the mark feature analyzer analyzes the traffic mark feature in the captured image and calculates a device coordinate according to the mark coordinate. The first coordinate fusion component fuses the device coordinate and a first fusion coordinate and uses fused coordinate as a second fusion coordinate. The second coordinate fusion component fuses the second fusion coordinate, traffic carrier inertial information and a global positioning coordinate and uses fused coordinate as an updated first fusion coordinate.
