On October 26, 2018, the Changsha Municipal Government issued the first batch of intelligent road network open road test number plates in Changsha, and announced the first phase of the open road test section in Changsha. The 12-meter intelligent driving bus of Zhongche Electric successfully obtained the number plate. And became the first self-driving bus in the country to obtain the intelligent network connection vehicle open road test number plate.
'No dead angle'
'South of Xiangjiang New District Intelligent System Test Area, north to the intersection of Yunqi Road and Hanpu Avenue, with a total length of 7.8 kilometers, a total of 11 groups of 22 intermediate stations. ' As the country's first open road automatic driving bus demonstration operation line Changsha Smart Network's open test road has long lines and multiple road conditions, covering many complicated scenes. After the car's electric automatic driving bus successfully obtained the number plate, it will be tested on this line.
In order to fully meet the test requirements, this open test road is also equipped with a customized intelligent driving network system, customized intelligent supervision network system, customized intelligent network data management software platform, road video monitoring system, electronic police and traffic police Video surveillance system, network communication and security system, and 5G-based V2X system and other comprehensive intelligent system design. At that time, CRRC's intelligent driving bus will stage a smart driving with almost no dead angle on this road. Technical training.
'The country's first open road auto-driving bus demonstration operation line + the first self-driving bus that won the intelligent network connection vehicle open road test number plate' will become the biggest point of view in the future test operation.
Smart driving and then upgrading
With the deepening of research on CSR electric in the field of intelligent driving, intelligent driving new energy bus has reached the open road fixed route demonstration operation level.
The 12-meter intelligent driving bus launched by CSR Electric has been upgraded in three aspects compared with the previous one. Wang Wei, deputy general manager of CRRC, said: 'Firstly, the car networking system is added in terms of perception, and the car road coordination can be realized. Communication function, in which the identification of traffic lights and road signs is added to the sensing system for the first time. That is to say, after the red light is encountered during driving, the intelligent driving bus will automatically stop. If the road ahead has a limited speed sign, the vehicle will also be in accordance with the requirements. Reduce the speed of the vehicle. Secondly, optimize the perceptual fusion algorithm. The sensor's focus and recognition ability are different. The domain controller is configured to realize the depth perception fusion, improve the recognition performance of the obstacle, and improve the position of the obstacle. The accuracy of information such as relative speed. Thirdly, the forward design, front loading mode and optimized layout for the intelligent driving device make the overall appearance of the vehicle more fashionable and atmospheric.
From the world's first 12-meter pure electric intelligent driving bus in 2017, to the officially obtained the intelligent road-connected vehicle open road test number plate, CRRC Electric has continuously tested and upgraded, and formed a rich system in the technology development and application of the intelligent driving bus. Integration experience. In the future, CRRC Electric will continue to showcase the advanced intelligent driving technology of China's advanced new energy buses with the most advanced intelligent driving technology, and promote the high-quality development of national intelligent manufacturing.
