(1) TOKYO, May 25, 2021 - (JCN Newswire) - Hitachi Astemo, Ltd. has developed "Dynamics Planning", a highly precise vehicle trajectory planning technology for AD ECU(1). The technology uses an algorithm to control unpleasant sway and acceleration in Level 3 vehicles and promotes a comfortable driving experience. The development of automated vehicle technology is not only about getting the vehicle to its intended destination without driver control, but getting there safely, comfortably, and quickly. Comfort in the vehicle becomes particularly important as the level of automation increases, freeing the driver from the controls. Currently, a skilled driver is required to make effective use of lane width and speed to create a gentle trajectory and smooth changes in acceleration when driving around bends. This helps to keep the cabin comfortable and reduces unpleasantness from irregular acceleration and sway. However, today's conventional advanced driver assistance technologies do not replicate a skilled driver. The vehicle instead attempts to travel at a constant speed along a path close to the center of the lane, causing an unpleasant sway.
