Panasonic develops Driverless Automated Valet Parking system and a large screen AR-HUD
Society is increasingly seeking to build a safer, more comfortable automotive society through advancing automated driving and reducing traffic accidents. To achieve this goal, 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.
Driverless automated valet parking system works 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.
Driverless automated valet parking accomplishes parking in a very narrow space up to a minimum of 20cm clearance between cars, because it is unnecessary to open or close the doors after parking. An in-vehicle emergency braking system that detects people by using deep learning helps to prevent accidents. This system was developed with in-vehicle ECU applications in mind. It accurately recognises pedestrians with minimal calculations.
Today, ADAS is more widely used to reduce vehicle accidents caused by drivers' mistakes. The driverless automated valet parking system achieves safe automated driving in a parking lot by combining in-vehicle ADAS sensing technologies (such as cameras, sonars, and radar sensors) with the infrastructure sensing technologies for security (such as surveillance cameras).
A vehicle with the automated valet parking function installed is linked to an infrastructure-sensing-based surveillance function via a local control server that is set up in each parking lot. The driver can give the vehicle remote instructions to enter or exit the parking lot via a controller such as a smartphone or tablet.
Infrastructure surveillance cameras monitor the parking lot for empty spaces and pedestrians. They ensure the safe, smooth guidance of the vehicle to the parking space. Pedestrian detection using deep learning is also used by infrastructure surveillance cameras. Because the positions of surveillance cameras are fixed, background subtraction based on fixed point observation is also utilised to help increase the sensing performance.
The control server link technology allows the vehicle to avoid pedestrians who may enter into the driving path. In addition to the in-vehicle emergency braking system, this technology safely stops a vehicle through the wireless transfer which is designed as an appropriate wireless communication area and prior traffic control, by sending braking instructions from the control server.
Large screen AR-HUD comprises of an image that gives a sense of depth is superimposed on the actual space in front of the driver's seat. 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 by using the company's proprietary optical technologies-refined through the development of audio-visual products-to reduce misalignment between the actual space and the image.
A high-quality, large screen display with minimal distortion is achieved by utilising Panasonic's optical technologies, which have been refined through the development of audio-visual products (including the development, processing, and production of digital cameras, surveillance cameras, projectors, and TV sets). The large screen display is equivalent to 230 inches at the centre of the display distance.
The vibration compensation technology incorporates Panasonic's proprietary image stabilization technology, which is used for products such as digital cameras. It reduces misalignment between the actual space and the displayed image that is caused due to vehicle vibration.
The HUD superimposes information on the actual view seen through the windshield. Information is projected in the driver's field of view ahead. The HUD indicates alerts (such as lanes and signs) and route information in a manner that is easier to see and understand than before.
