RUNNING CONTROL DEVICE AND METHOD FOR A VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240336260 titled 'RUNNING CONTROL DEVICE AND METHOD FOR A VEHICLE

The patent application describes a running control device for a vehicle that utilizes lane information to calculate a target steering angle and control the automatic steering device accordingly.

  • Lane information acquisition device and electronic control unit are key components.
  • Running control involves calculating target steering angle to adjust lateral position in the lane.
  • Lane curvature is calculated to estimate lateral acceleration of the vehicle.
  • Information about lane cant is obtained to calculate estimated cant lateral acceleration.
  • No running control is performed if the corrected estimated lateral acceleration exceeds a reference value.
    • Potential Applications:**

- Autonomous driving systems - Advanced driver assistance systems - Vehicle safety technologies

    • Problems Solved:**

- Enhancing vehicle stability and control - Improving lane-keeping capabilities - Mitigating risks of lane departure accidents

    • Benefits:**

- Increased safety on the roads - Enhanced driving experience - Reduced likelihood of accidents

    • Commercial Applications:**

"Advanced Lane-Keeping System for Autonomous Vehicles: Enhancing Safety and Control"

    • Questions about the Technology:**

1. How does the running control device improve vehicle stability? 2. What are the potential implications of this technology on the automotive industry?


Original Abstract Submitted

a running control device for a vehicle comprising a lane information acquisition device and an electronic control unit that performs a running control in which a target steering angle for bringing a lateral position of the vehicle with respect to a lane to a target position is calculated and an automatic steering device is controlled so that a steering angle becomes the target steering angle, and is configured to calculate a lane curvature based on lane information, calculate an estimated lateral acceleration of the vehicle based on the lane curvature, obtain information about a lane cant in front of the vehicle, and calculate an estimated cant lateral acceleration based on the lane cant, and perform no running control when a magnitude of the estimated lateral acceleration of the vehicle which is corrected by subtracting the estimated cant lateral acceleration exceeds a determination reference value.
