Hitachi Automotive Systems and Clarion showcase parking technologies at CES
At CES 2018, Hitachi Automotive Systems, Ltd. and Clarion Co., Ltd. announced the development of Park-by-Memory autonomous parking technology that remembers the environment surrounding users’ home parking spaces. Moving forward, the companies will aim for the initial adoption of this system through proposals to automotive manufacturers.
Park-by-Memory can be used to automatically park vehicles in frequently used parking spaces such as at home or at work. This technology was achieved by combining Clarion’s external recognition technology with steering and brake actuators and integrated vehicle control technology provided by Hitachi Automotive Systems.
To memorize parking environments and parking patterns, Park-by-Memory integrates bird’s-eye footage provided by SurroundEye, an original camera system by Clarion that is fitted to the left and right sides of the front and back of the vehicle, with detection data on surrounding structures obtained using sonar signals as well as GPS positional information. This enables vehicles equipped with Park-by-Memory to notify drivers that it is possible to park when the vehicle approaches memorized parking spaces. Drivers can initiate autonomous parking by simply pressing a button in the vehicle, or by using their smartphone app.
Park-by-Memory uses high-precision image recognition data from SurroundEye so that it can autonomously park in parking spaces of various shapes, including parking spaces only designated by white lines. In addition, the use of existing general vehicle navigation GPS information, rather than using a specialized positional information system, has facilitated the technology’s early introduction.
Valet Parking, another autonomous parking technology developed by Hitachi and Clarion, can be controlled via a smartphone app or from a remote management center. With Valet Parking, the vehicle drops off the driver and then parks itself in an empty space via parallel or perpendicular parking. The vehicle can also pick up the driver.
The system combines self-driving technology, automatic parking technology, and over-the-air technology. The remote parking system combines Clarion's SurroundEye camera monitoring system with Hitachi Automotive Systems' vehicle control units and steering and brake actuator control technology to park a vehicle remotely.
On the smartphone screen, the system provides a real-time image display of the vehicle’s surroundings as well as the route the vehicle is traveling, enabling the driver to operate the vehicle safely through automatic parking while always knowing about the surroundings. In addition, the smartphone applications employ an interface that is easy to use, with various choices such as perpendicular and parallel parking styles. The system makes it possible to park and de-park an unmanned vehicle.
A vehicle that is being automatically parked or de-parked can instantly be stopped by a screen operation on the smartphone if the driver detects a possibly dangerous situation. The vehicle itself has an automatic stop function that operates when its sensors detect pedestrians or obstacles in the vicinity.
