March 28, 2021
ShinMaywa Industries, Ltd. (Head Office: Takarazuka City, Hyogo Prefecture, President and CEO: Isogawa Tatsuyuki, hereinafter referred to as ShinMaywa Industries) and National University Corporation Gunma University (President: Hiroshi Hiratsuka, hereinafter referred to as Gunma University) have been in partnership since December 2017. We have started "joint research to realize the use of mechanical car parking systems for self-driving cars *1 (hereinafter referred to as self-driving cars)," and in July 2019, we will automatically advance to a verification device that assumes elevator type car parking system We have advanced our research to date, including being the first in the industry to succeed in parking. Recently, on the premises of ShinMaywa Industries Head Office head office, self-driving cars will be able to automatically enter and exit the elevator-type and two- and multi-level mechanical car parking systems, as well as a combination of multiple communication and guidance methods. We conducted a demonstration experiment of a road control system that realizes automatic driving between facilities, and succeeded in the following three items.
- Establishment of backward parking technology for the industry's first two- and multi-level parking facility
- Construction of a unique "vehicle guidance system" (including roadway control function) assuming spaces where GPS cannot be used, such as underground.
- Automatic valet parking, including opening and closing of entrance doors for elevator systems and two- and multi-level parking facilities *2
By realizing item 3 above, and in anticipation of the future spread of self-driving cars and accompanying social changes, we will be able to prepare communication environments and guidance methods for mechanical car parking systems and its surrounding infrastructure, and coordinate with self-driving cars. , we have established a technology that guides self-driving cars to mechanical car parking systems and parks them with high precision while paying attention to safety.
By applying this technology, automatic valet parking becomes possible even in underground spaces where GPS is difficult to reach, private land where there is no map information, etc., and as a result, there is no need for people to enter parking areas including mechanical car parking systems and road leads. Since this eliminates the risk of causing personal injury, we are getting closer to realizing a safe and convenient mechanical car parking systems eliminates the risk factors that can cause personal accidents.
- *1 Self-driving car: Here refers to an experimental vehicle owned by Gunma University.
- *2 Valet parking: A service provided at hotels etc. that handles the entry and exit of cars, etc.
1. Recent research results
- In areas that are assumed to be private land (including areas where GPS radio waves cannot be received), everything from self-driving using GPS to guided driving using a proprietary roadway control system, to parking in and out of elevator-type and two- and multi-level parking facilities. Successful in a series of operational tests
- The Head Office 's first successful demonstration experiment of "reverse parking" by an autonomous vehicle at a two- and multi-level parking facility (testing machine) with a narrow front road on the grounds of ShinMaywa Industrie's head office.
- Through the development of a "vehicle guidance system" with road control and blockage control functions, it uses landmarks (QR codes), line traces, and sensors to accurately guide self-driving cars to mechanical car parking systems, and to control automatic door openings. Automate a series of parking operations including opening and closing
- Blockage control using APPS (Advanced Pilot Parking System) prevents collisions with vehicles in front and behind or with people during automatic parking.
- With the recent establishment of a series of technologies, automatic valet parking in mechanical car parking systems is possible without human intervention, reducing the risk of parking-related troubles and personal accidents.
- At Gunma University, we will accelerate research toward the realization of a further autonomous driving society, including the results obtained from the recent demonstration experiment.
- ShinMaywa Industries will move to a research and development phase that envisions a society in which manually driven cars and self-driving cars coexist, including the utilization of the technology established this time, as well as the construction of systems including road control around parking lots. , is exploring the development of new businesses related to parking, such as parking solutions business.
2. Results of this research (details)
(1) Realization of the industry's first automatic reverse parking system - Cooperation between self-driving cars and mechanical car parking systems-
Through the operation of the jointly developed APPS (Advanced Pilot Parking System) and "V2P" (a system that connects autonomous vehicles (V) and mechanical car parking systems (P) through communication), autonomous vehicles and mechanical car parking systems cooperate (send and receive necessary data and signals) to safely and accurately guide self-driving cars to parking spaces. Specifically, in a narrow area with a front roadway width of 5.5 meters, the self-driving car performs a reverse maneuver that requires more advanced driving skills than automatic forward parking, which was successful in 2019. (Back) We have realized automatic parking when parking.
As a result, we have established technology that can accommodate a wider range of parking lots, and opened up the possibilities for mechanical car parking systems in future society.
"Communication/guidance method" and its features
Automatic reversing (reversing) parking to a two- and multi-level parking facility with a front driveway of 5.5 meters
(2) Building an automatic valet parking systems for mechanical car parking systems- Automating a series of operations from around the equipment to entering and exiting the garage -
Features of ShinMaywa-style automatic valet parking
- 1 To guide self-driving cars from the roadway to mechanical car parking systems, the infrastructure side uses landmarks (QR codes), line tracing, etc., and combines communication methods suitable for the situation, such as Wi-Fi and 4G. Build a self-driving vehicle control system (“vehicle guidance system”).
- 2 Safety is also ensured by establishing occlusion control using LiDAR.
- 3In the parking situation, communication between the self-driving car and mechanical car parking systems automates a series of operations such as summoning a pallet and automatically opening and closing entrance/exit doors.
The main routes through which we conducted demonstration experiments are as follows.
