Toyota concept car LQ to get Panasonic ADAS level 4 system

by Autocar Pro News Desk , 14 Oct 2019

Panasonic has developed a driverless automated valet parking system and an AR-HUD (Augmented Reality Head-Up Display). The driverless automated valet parking system achieves fully automated driving (SAE Level 4) in limited areas, while the AR-HUD offers safe, comfortable navigation so that the user can concentrate on driving. These technologies will be installed in Toyota Motor Corporation's concept car, LQ.

Panasonic claims that this system is achieving driverless automated valet parking without dedicated expensive sensors. It accurately identifies the position of own vehicle by using multiple conventional in-vehicle cameras, sonars, and radar sensors as well as a 2-D road map. The system enables safe parking by finding an empty space and detecting pedestrians who enter the roadway by linking to surveillance cameras in a parking lot and a control server. The system also comes with the ability to maintain a minimum of 20cm clearance between cars and in-vehicle emergency braking system that uses deep learning to prevent accidents.

The major benefit of this system is that it reduces the traffic, mishaps and stress related to parking. This also helps in the efficient use of the parking lots in the vicinity.

Based on the information from the vehicle, the AR-HUD indicates route information and obstacle alerts just like physical markings on the road. It presents a high-quality image on a large screen with minimal distortion in the space on the windscreen right in front of the driver, by using Panasonic's proprietary optical technologies--refined through the development of audio-visual products--to reduce misalignment between the actual space and the image.

Panasonic claims that the new AR-HUD will assist in safe driving by reducing the movements and focus readjustments of the driver's eyes by presenting information intuitively.  It also reduces the misalignment caused by vibration between the actual space and the displayed image by using proprietary vibration compensation technology, achieving navigation that is easier to see and understand. With Panasonic's optical technologies, the large screen display is equivalent to 230 inches at the centre of the display distance.
