Hitachi Group to develop basic technology for preventing collisions by predicting changes in pedestrian movement, aiming to commercialize autonomous driving on local roads
Hitachi, Ltd., Hitachi Automotive Systems, Ltd., and Clarion Co., Ltd. today announced that they have developed the basic technology for preventing collisions while maintaining safe and practical speeds by predicting changes in pedestrian movements and rapidly calculating optimum speed patterns in real time.
Tests using experimental vehicles were conducted to verify the validity of the new technology. Results showed that it was possible to achieve practical speeds for passing through pedestrians and driving within the standard comfortable speeds for acceleration (2.2 m/s2 or less) and for change of acceleration (2.0 m/s3 or less).
Going forward, the Hitachi Group will conduct further tests using experimental vehicles in different driving environments, including Mcity opened at the University of Michigan in July 2015 as a controlled environment for conducing tests on autonomous vehicles and connected cars.
