1. Autonomous Driving Unit and High-definition Map Position Unit
Since releasing an advanced driver assistance system (ADAS) unit in 2000, the Hitachi Group has released a number of information-based safety products such as stereo cameras and gateway units. In 2019, it started mass-producing an autonomous driving unit and high-definition map position unit using technologies acquired from developing autonomous driving systems.
The autonomous driving unit is configured with two central processing units (CPUs) for vehicle control and recognition, enabling a high level of safety and high-speed computing performance. The high-definition map position unit stores high-definition map data covering features such as Japan’s nationwide highway network. It sends look-ahead information not visible to sensing technology to the autonomous driving unit. A satellite positioning system has been combined with a gyro sensor to develop a function that computes the vehicle position with high accuracy even in tunnels or other areas of weak satellite signal. Using another developed function, the route to the destination set in the car navigation system is converted from a route showing each road to a route showing each vehicle lane. The high-definition map position unit outputs information along with high-definition map data of the area around the vehicle to the autonomous driving unit.
Hitachi will continue to draw on its identity as a supplier of autonomous driving systems to help create safe and comfortable driving experiences driven by advances such as original Hitachi over-the-air (OTA) software updates and security technologies.
