Recently, the "three highs" test team of Zhongtong Bus rushed to the Heihe Automobile Alpine Test Base in China to conduct the test of the H12 extreme cold area of the super bus. Heihe River, extremely cold land, snow cellar ice weather, unique climate and geographical conditions, for the vehicle extreme cold resistance test test provides a rare test environment.
The alpine test is an important part of the reliability evaluation of the car, which will put forward strict requirements for the environmental adaptability, handling and performance reliability of the whole vehicle.
In January 2022, a "confrontation" between buses and extremely cold environments began. In nearly half a month of testing, the test team of Zhongtong Bus conducted a comprehensive test on the reliability, stability and durability of the H12 operating system of the super bus, thermal management system to electronic appliances, and handed over a satisfactory answer.
Ice and snow ring test is a kind of verification of vehicle operation stability, the vehicle in the adhesion coefficient of only 0.1 ice surface road condition test, the body electronic stability control function in time to intervene in the vehicle skidding and turning to help trim the driving trajectory, incarnated as an ice dancer, Ling Frost proud snow.
The serpentine test is to let the vehicle continuously pass through the pre-set 10 * 30 meters obstacle pile, through the measurement and monitoring of the vehicle's swing, the stability of the body posture and other data to investigate the vehicle performance, the super bus H12 is elegant and flexible, and the 10-50km speed band shows extremely high handling stability, which in addition to requiring superb driving skills, it is inseparable from the good performance of the vehicle.
The drive anti-slip function plays an important role in improving vehicle safety, handling stability and drive acceleration on low-adhesion roads. The H12 super bus starts on the ice and accelerates well, maintaining the car's directional stability and steering control.
In the course of the stable road experiment, the super bus H12 can efficiently resist external interference and maintain a stable driving ability when encountering emergency steering, rapid acceleration, etc., the body can always ensure a stable posture, and the measuring cup full of water in the car does not leak, bringing an excellent riding experience to passengers.
In extremely cold temperatures, vehicles face another problem, that is, whether the performance of the vehicle cold start, vehicle energy consumption and component durability can withstand the test. Throughout the test process, the H12 vehicle of the super bus can successfully achieve a one-time cold start after sitting in the extremely cold environment of -30 ° C for more than 12 hours, the various electronic components carried on it are operating normally, and the heating can maintain the temperature of the cabin at 15-16 °C, meeting the needs of passengers for ride comfort in harsh environments.
The whole test process, this is not only a test of the quality and reliability of the vehicle, but also a review of the test team - in order to make the product high-quality delivery to customers, the test team overcame the challenge of harsh conditions, stuck to the post every day to carry out vehicle preparation and track the test process, and finally completed the entire alpine test on the eve of the Lunar New Year, collected rich test data, enriched the alpine test database of the Zhongtong brigade, and laid a solid foundation for the stable performance of the tour bus of Zhongtong Bus in the harsh environment.
Super bus H12, stable performance in harsh environments, is self-confidence, but also strength! After the excellent performance under the extremely cold conditions, it is believed that in the future, the super bus H12 will be more recognized, rush to more markets, and provide more comfortable, convenient, safe and reliable high-end travel services.
