Bosch provides all major components of the system and has started a strategic cooperation with the Chinese Contemporary Amperex Technology Co. Limited (CATL) on battery cells for its 48-volt battery.
Electric Vehicle and high-voltage Hybrid Electrification System (400V)
Bosch offers solutions for all types of powertrains including high voltage hybrid systems combined with a combustion engine system, in addition to electric drive system. The core of this system is the new powertrain "eAxle" for EVs (Electric Vehicles) and PHVs (Plug-in Hybrid Vehicles) that integrates a motor, inverter, and transmission. The module, though compact, greatly optimizes efficiency and achieves the industry's highest efficiency at 93%. Mass production of "eAxle" is to begin in 2019 and is expected to appear in the Chinese market in 2020.
First time in Japan: Web-based validation brings about efficient development
Bosch conducts validation of its connected solutions with the cooperation of automobile manufacturers. In the past, staff from Bosch and automobile manufacturers gathered at the same place to verify systems and test vehicles, but now, Bosch is pushing forward the development of web-based validation, which performs web-based operations from data sharing to software updates and vehicle applications. By sharing data acquired from test rides and verification experiments around the world, and updating the systems and software of connected cars through the cloud, the web-based validation allows a more convenient and efficient development to be carried out and realizes a shorter development time. At the Tokyo Motor Show, the web-based validation will be introduced through a video presentation.
Thermal management – setting the right temperature in electric cars and hybrids
Bosch uses intelligent thermal management to increase the range of electric and hybrid vehicles. Precise distribution of heat and cold improves the efficiency of the battery and ensures that all components are working within their optimum temperature range. Also cabin climate control is integrated in the thermal-management system which delivers a pleasant temperature inside the vehicle
[Automation solutions for a safer mobility]
First time in Japan: Concept model with advanced rider assistance system (Ducati)
Bosch's advanced rider assistance systems support motorcyclists by improving the safety of two-wheeled vehicles and rider comfort. It comprises "ACC" (Adaptive Cruise Control), which maintains a safe distance from the vehicle ahead, "Collision warning system", which warns the rider under conditions where there is a risk of collision with the vehicle ahead, and "Blind-spot detection", which supports the safe changing of lanes. Bosch started public road trial testing of an advanced rider assistance system in Japan in March 2019. This is the first police-notified public road testing of an advanced rider assistance system in Japan. Bosch plans to start series production from 2020. It has already been decided that the system will be mounted on Ducati and KTM models, and with the cooperation of Ducati, a concept model equipped with the advanced rider assistance system will appear at the Tokyo Motor Show, the first time such a system has been displayed in Japan.
Radar sensors – surround sensors for complex driving situations
The latest generation of Bosch radar sensors are even better at capturing the vehicle's surroundings. Their greater detection range, wide aperture, and high angular resolution mean that automatic emergency braking systems can react more reliably.
Front camera – image processing with algorithms and AI
Bosch's front camera detects objects by combining image-processing algorithms with AI methods. The new camera's great strength lies in its robust object recognition, enabled by Bosch's multi-path approach. In congested urban traffic, it can for example recognize and classify partially obscured or crossing vehicles, pedestrians, and cyclists quickly and reliably.
At the Tokyo Motor Show, Bosch will display its interactive station, which allows visitors to access the features and view of the cameras and radars, which are indispensable for detecting objects around the car. In addition to object detection technology, Bosch will introduce key technologies for automated driving, such as vehicle localization estimation technology, on-board computer for automated driving, redundant brake system and cybersecurity.
Electric power steering – Servolectric®
Bosch is one of the few suppliers in the world who can handle the steering system control unit. The steering system control unit is the hardware integrating ECU and the assist control software, which becomes the key to the steering system. Bosch's fail-operational electric power steering system, Servolectric®, has a redundant design so that even in the unlikely event of a failure of the electrical system, the electrical assist can continue to operate without stopping suddenly, and supports SAE levels 2 through 4/5 (fully automated driving) for automated driving. In addition, Bosch has been developing the steering system, taking account of a steer-by-wire system that will use electric signals to control the steering actuator. Servoelectric® was developed using modular design principles, to ensure wide compatibility regardless of automation level, and to reduce the burdens involved in developing steering systems. A common controller is used so that various outputs can be supported by employing a motor according to the assist capability of the steering.

First time in Japan: Interior monitoring system
Monitoring the driver inside the vehicle to identify situations where the driver micro-naps, take their eyes off the road, is distracted, and so on, will become increasingly important in the future. Bosch's in-vehicle monitoring system accurately detects the state of the driver and warns the driver when necessary. This system not only contributes to improved safety, but also plays an important role in improving comfort.
Next-generation integrated cockpit
One trend is the integration of a computer workstation that controls multiple devices and operating systems inside the cockpit. Through integrated and centralized management of the infotainment feature, instrument cluster, and so on, cooperative control of content is realized, expanding the possibilities for new expressions. Bosch has experience and know-how in relation to products and technology expertise that comprise the integrated cockpit, and can safely and comfortably provide a next-generation cockpit.
Connected parking and interactive station
Bosch is developing connected parking technology that significantly reduces the effort needed and time spent for parking, while also reducing dents and scratches while parking. In 2019, the automated valet parking system developed by Bosch and Daimler was the world's first driverless SAE Level 4 parking function to be officially approved, and even in Japan, Bosch is the first globally to work on initiatives such as proof-of-concept for applying the automated valet parking technology to low-speed, unmanned vehicles at logistics-related facilities. At the Tokyo Motor Show, three use cases of connected parking solutions will be introduced at an interactive station: "Community-based parking", which provides the driver with real time information on parking spaces, "Automated valet parking", which enables automatic parking by simply operating a smartphone, without requiring a driver, and "infrastructure-coordinated new vehicle transport applying valet parking", which realizes unmanned automation of vehicle transport.
Prevent digital theft of vehicles with Perfectly Keyless
Bosch's Perfectly Keyless system communicates via Bluetooth between the driver's smartphone and their vehicle, and it enables drivers to lock and unlock their vehicle and start the engine without needing an actual key. And thanks to its decades of experience in semiconductors, Bosch is in a position to make this connection as secure as a fingerprint. Every smartphone contains tiny microchips to manage communication via Bluetooth, and these play a key role in the Bosch solution. Together with sensors installed in the vehicle and a special control unit, they form a system that opens the door only for the smartphone containing the virtual key that fits in the Perfectly Keyless system's digital lock. In addition, because the digital key can be managed via the cloud, the key can not only be delivered with ease, but it can also be managed securely, and it prevents unauthorized access. Bosch will demonstrate how Perfectly Keyless works at the Tokyo Motor Show.
