New interconnected services make the first line of freight and logistics easier

Cloud service-based interconnected platform: Bosch achieves the interconnection of commercial vehicles throughout the service cycle through a new interconnected platform, providing technical support for cloud services such as predictive diagnostics and wireless software updates. The new platform has two main components: the basic software module and the data management module. Among them, the basic software module is a secure communication interface for vehicles, clouds and services, and the data management module helps commercial vehicle manufacturers or fleet managers to better plan and analyze vehicle data and update vehicle software in time.

Predictive diagnosis: Vehicles are often prone to unexpected failures. And when these failures occur in commercial vehicles, they often cause significant economic losses. Bosch's predictive diagnostics record and evaluate the status of vehicle components and systems, and continuously transmit information to the cloud. Based on these data, failures can often be predicted and resolved in a timely manner, reducing the cost of repair and service for commercial vehicles, and reducing the number of failures increases the utility of the vehicle.

Electronic Horizon: Bosch Electronic Horizon will become smarter and more popular in the future. A high-definition map with terrain data from the front route provides the basis for this service. Vehicle engines and transmissions will select the most efficient driving solution based on these data to further reduce energy consumption. The electronic horizon has been around for many years, and now Bosch has further improved its performance. In the future, this feature will be sufficient to determine whether the built-in information of the map is consistent with the actual road conditions. For example, the on-board camera detected a road speed limit of 30 km/h, but the map shows a speed limit of 50 km/h. The truck-mounted navigation system will remember the new speed limit regulations. In the future, this information will also be shared with other trucks through the cloud. The electronic horizon will be put into production in early 2019.

Freight monitoring: Logistics specialists and customers often worry about the real-time location and shipping status of the goods. Bosch Logistics Transport Data Logger can solve such problems and realize the transparency of the cargo supply chain. The recorder is a small box with a size of about 10 square centimeters. It has built-in integrated sensors that can monitor the transportation of sensitive goods and measure the temperature, humidity, inclination and vibration during transportation. The measurement data can be displayed on the smartphone. Or in the tablet app and documented. If a certain value is exceeded, the application triggers an alert to detect potential cargo damage threats early and find the responsible person.

Central Gateway: The central gateway controls the data exchange between the truck electronic control unit and the external world in all bus systems, and is the central communication node of the connected commercial vehicle. Modern transmission and encryption technologies enhance the security of data exchange, and the intrusion detection system developed by the Bosch subsidiaries ETAS and ESCRYPT can prevent illegal access to the vehicle network.

Digital rearview mirrors and displays improve driving experience for increased safety

Digital rearview mirror: The digital rearview camera system developed by Bosch and Merkel for rearview mirrors will be officially put into production in 2019. The system replaces the large rearview mirrors on both sides of the cab with image sensors to reduce windage and reduce fuel consumption by 2%. The image returned by the camera will be displayed in real time on the high resolution monitor in the cab. The system adjusts the display according to different conditions: when the truck is driving on the highway, the display field of view will be adjusted further; when driving in the city, the angle of view will be enlarged; when driving at night, the image contrast will be enhanced . With the EasyFit camera system from Bosch, the existing truck fleet can also be equipped with digital rearview mirrors. The EasyFit system is based on four super wide-angle cameras that provide 360-degree visibility of the vehicle's surroundings.

Digital Dashboard: Bosch introduces digital dashboards into the cockpit to ensure uninterrupted operation of the ever-expanding truck interconnect, driver assistance and in-vehicle infotainment. In addition to the traditional speedometer view, the dashboard will also display vehicle function information, route planning graphics, and images transmitted by the reversing camera or night vision device, prioritized based on driving conditions. At any given moment, the dashboard provides accurate information that the driver needs, reducing driving complexity and allowing them to focus entirely on the road.

Driver assistance system enhances the driving experience of commercial vehicles

Turn warning: In the city, especially in the central area, truck drivers should not only pay attention to vehicles, lights and road signs, but also pay attention to the safety of pedestrians and cyclists. In the future, Bosch's steering warning system will help the driver to complete operations in complex situations: the radar sensor will allow sufficient time to detect nearby pedestrians and cyclists and issue a collision warning to the driver so that they can quickly brake or take evasive action.

Blind zone identification: It is difficult for commercial vehicle drivers to see the situation around and behind the slope, whether on urban roads or on highways. Blind zone identification can monitor the surrounding area of ​​the vehicle through radar sensors, detect other road users, and warn the driver. This function also alerts the driver to collisions when changing lanes.

Predictive emergency braking: Since the fall of 2015, the European Union has required the installation of a commercial vehicle automatic emergency braking system for trucks with a total weight of more than 8 tons. Bosch assists the driver by installing a multi-function camera and radar sensor at the front of the truck. The radar sensor is capable of detecting objects in front of the vehicle and determining the speed of the object and its relative position to the vehicle. The system warns the driver if there is a risk of collision. If the driver does not respond, the system will automatically trigger an emergency brake.

Lane assist: The lane assist system uses camera data to ensure that the truck does not accidentally deviate from the lane. The lane departure warning alerts the driver of the danger of deviating from the lane by means of, for example, a vibrating steering wheel. The lane keeping assistant ensures that the vehicle is always on the established lane with a slight steering intervention.

Bosch commercial vehicle steering system guides the way forward

Servotwin steering system: Bosch Servotwin electro-hydraulic steering system increases the efficiency and convenience of heavy-duty commercial vehicles. It provides on-speed steering support with less fuel consumption than pure hydraulic steering. Thanks to the electronic interface, the steering system also guarantees driver assistance functions such as lane assist and crosswind compensation. The system has many application areas, including Mercedes-Benz's self-driving truck Actros.

Rear axle steering: With the electric rear axle steering system (eRAS), the commercial and rear axles can be used for three- or more-axle commercial vehicles to reduce the turning radius and reduce tire wear. The steering system is based on the steering angle of the front axle and is transmitted via the CAN bus to determine the optimum steering angle of the rear axle. After the bend, the system also took on the task of straightening the wheel. The rear axle steering system consumes fuel only when the vehicle is actually turning.
