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

This abstract first appeared for US patent application 18625832 titled 'RUNNING CONTROL DEVICE AND METHOD FOR A VEHICLE

The patent application describes a running control device for a vehicle that calculates a target steering angle to bring the vehicle's lateral position in a lane to a target position and controls the automatic steering device accordingly.

• Lane information acquisition device and electronic control unit work together for running control.
• Calculates lane curvature and estimated lateral acceleration based on lane information.
• Obtains information about lane cant in front of the vehicle.
• Calculates estimated cant lateral acceleration based on lane cant.
• No running control if corrected estimated lateral acceleration exceeds a reference value.

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.
