Toyota: "SDL (Smart Device Link)" service for linking car navigation systems and smart phones

Toyota exhibited the SDL (Smart Device Link), a service that links the smart phone to car navigation systems. At the booth where the Toyota Prius and Daihatsu Move Canvas were on display, as part of the SDL service, a demonstration was conducted showing the exchange of messages by LINE using the voice recognition system of the car navigation system while driving.

In June 2018, LINE announced the “Clova Auto” service that connects the AI assistant “Clova” to car devices. Both companies are planning to launch SDL-based car navigation systems in December 2018 starting with LINE MUSIC and making “Clova Auto” available for use from 2019.

The two vehicles exhibited were both equipped with SDL-based car navigation systems. The car navigation and smart phone is linked by Bluetooth before activating the “Clova Auto” service. The driver can then operate Clova Auto the same as he would the car navigation system, even while driving, using functions such as the display, audio guide, microphone or steering switches, to operate the smart phone application to send and receive LINE messages.

Valeo: "XtraVue" connected computer vision camera

Valeo’s first exhibition at CEATEC showcased the “XtraVue”, a system that eliminates visual obstacles. Two demo vehicles were lined up in the booth where the display inside the rear vehicle projected an image of the front car obstructing the field of vision as a see-through image. The demonstration exhibited in real time how the preceding car does not appear in the driver’s field of view, offering an enhanced view of the road ahead.

XtraVue is an image recognition system comprised of a telematics antenna, laser scanner, and cameras. By making use of the future 5G (5th Generation Mobile Telecommunications System) and V2V (Vehicle-to-Vehicle) networks and by performing image processing by streaming information from multiple cameras such as those installed on road sides or from other vehicles, the system is able to provide comprehensive information on the surrounding environment beyond the driver’s line of sight.

During the Valeo press conference, in addition to the XtraVue system, the company also introduced its SCALA laser scanner. The first generation SCALA started production in 2017 and is used on the Audi A8. The second-generation SCALA 2 is scheduled to start production in 2020 and was also exhibited in the booth. Furthermore, by 2020 Valeo plans to introduce the SCALA Cocoon, a combination of multiple SCALA systems performing 360-degree object detection. During the introduction of its Cruise4U automated driving system, Valeo stated that a vehicle equipped with SCALA laser scanners (6 units), front camera, surround view cameras (4 units), radars (4 units) is currently being tested on a driving tour on Japanese expressways.

In addition, NTT Docomo’s approach towards collaboration in the connected car business arena was also introduced. In April 2018, the two companies announced their approach to mobility services such as offering on-board devices and communications services for connected cars, the development of next generation mobility services providing digital services for cars using smart phones in anticipation of the coming age of 5G and V2X (Vehicle to Everything), and the development and offering of solutions to control on-board devices.
