A few days ago, Volvo Trucks introduced the company's latest technological achievements on the official website. The company integrated laser scanning, infrared detection, monitor monitoring, camera detection and radio communication to solve the problem of blind spots during the right turn of the truck. .
Carl Johan Almqvist, Volvo Truck Transportation Product Safety Business Director, said that the application of trucks in urban areas is inevitable, but the status of safety problems still needs to be improved. The right side turns to the focus of safety issues in particular.
Compared with cars, huge trucks have more blind spots. Although many vehicles are equipped with more than 4 rearview mirrors to improve rearward vision, it is still difficult for drivers to ensure timely observation of approaching pedestrians and bicycles. Turning scenes increase the difficulty of obtaining peripheral visual information, which is a high-risk situation of hidden dangers in blind areas. Statistics clearly show that: 20% of accidents involving trucks hitting pedestrians and bicycles occur when the truck turns right at the intersection .
Malte Ahrholdt, Volvo ’s technical project manager, explained: “If you stop at a red light, the surrounding environment is constantly changing when the vehicle is stationary. If the driver is focused on something, such as a traffic light or looking for a gap in the traffic ahead , The situation behind the vehicle is difficult for the driver to grasp. Especially bicycles can easily pass through the gap between motor vehicles. In this critical situation, the warning signal and the sound of the reminder are particularly important. "
Malte Ahrholdt is currently participating in the Intersafe-2 project invested by the European Union. The project is dedicated to improving the safety of road traffic for a total of three years and will end in May 2011. A total of 11 companies and academic institutions from 6 countries participated, including: BMW, Volvo, Volkswagen, TRW TRW, VTT, Sick, Inria, NEC, Cluj-Napoca University of Technology (Cluj -Napoca), IKA and Swarco Traffic Systems. Volvo Trucks is mainly responsible for solving the blind spots of trucks facing pedestrians and bicycles when turning, and collaborating with Volvo Technical Department. Other participating agencies are responsible for other security detection content.
In the truck platform used for testing, Malte Ahrholdt and his colleagues added a laser scanner and ultrasonic sensors to the vehicle to monitor the area on the right side of the vehicle. If the bicycle or pedestrian is too close, the signal lamp will light up and the alarm sound will also It will sound and serve as a reminder to the driver.
