STATIC-STATE CURVATURE ERROR COMPENSATION CONTROL LOGIC FOR AUTONOMOUS DRIVING VEHICLES

In one embodiment, static-state curvature error compensation control logic for autonomous driving vehicles (ADV) receives planning and control data associated with the ADV, including a planned steering angle and a planned speed. A steering command is generated based on a current steering angle and the planned steering angle of the ADV. A throttle command is generated based on the planned speed in view of a current speed of the ADV. A curvature error is calculated based on a difference between the current steering angle and the planned steering angle. The steering command is issued to the ADV while withholding the throttle command, in response to determining that the curvature error is greater than a predetermined curvature threshold, such that the steering angle of the ADV is adjusted in view of the planned steering angle without acceleration.

DRIVING ASSIST SYSTEM

A driving assist system executes driving assist control for avoiding a collision with a target ahead of a vehicle. The driving assist control operates when the target exists within an assist area. A crossing target is the target crossing a roadway area ahead of the vehicle from a first side toward a second side. The assist area for the crossing target is divided into a plurality of divided assist areas including a first assist area located on the first side as viewed from the vehicle and a second assist area located on the second side as viewed from the vehicle. When the crossing target exists in the second assist area, the driving assist system decreases a control strength of the driving assist control as compared with a case where the crossing target exists in the first assist area.
