On January 13th, sponsored by the National Electric Bus Electronic Control and Safety Engineering Technology Research Center and undertaken by Yutong Bus, the "Ice and Snow Challenge Who Competes with the New Energy Bus Ice and Snow Challenge" was launched at the Yakeshi Bingfeng Automobile Camp!
Ling Frost proud of the snow, not afraid of extreme cold - this is China's pure electric bus ice and snow challenge, in the extremely cold environment of -40 ° C, Yutong bus is not afraid of ice and snow, no fear of extreme cold, a pure electric bus "ice and snow trial" opened the curtain.
10*40 meters snow around the pile for 35 seconds zero errors
Yutong pure electric bus performance is higher than the national standard 20%!
Yakeshi City has a low temperature and ice sealing period of up to 6 months in winter, and the average temperature in January is below minus 30 °C, making it the best place for new energy vehicles to test.
Rough roads, one-sided bridges, limited width doors, extreme winding piles... As a "ice and snow challenge", many difficult projects in the conventional environment appeared in the ice and snow arena, and the difficulty was upgraded and exciting. One after another pure electric bus "big", have transformed into ice dancers, frost proud of snow, elegant showmanship, maneuverability.
The car used in this event is a pure electric bus actually operated by Yutong, which is operated in Mohe, Harbin and other places, and has been tested by the market in cold areas.
In the extreme pile winding link, the total length of the track is 400 meters, requiring the runners to drive around 10 piles in one go, and the final first place takes only 35 seconds. 10 * 40 meters snow around the pile, 35 seconds zero mistakes, in accordance with the national standard requirements "50 meters pile distance tarmac" test vehicle stability, Yutong this challenge score is higher than the national standard 20%! The reason for such achievements is that in addition to the driver's superb operation skills, it is inseparable from the superior performance of the vehicle. Yutong pure electric bus turning diameter can reach 17.4 meters, more conducive to control. At the same time, the vehicle adopts a small hand steering device, which is lighter and can alleviate driving fatigue.
In the fun part, the eye-catching curling competition was "rehearsed" here.
Only to see that within a distance of ten meters, the player controls the vehicle, aims at the bullseye, pushes the curling forward with a speed limit of 30km/h, brakes near the red line, pushes the curling to the bullseye, and the best result is that the curling is 0.1 meters from the bullseye, and the accuracy is almost perfect. To achieve such a braking effect, it relies on the standard AEBS brake assist system of Yutong buses, which achieves a minimum braking distance of 8.6 meters on the ice surface of 30km/h.
In the stability competition, the vehicle carries a measuring cup filled with water, reverses the circle on the curve, and the person who spills the least water in the cup and takes the shortest time wins. The first place took only 1 minute and 33 seconds. Yutong's self-developed 360 panoramic surround view system provides escort throughout the process, predicts the driving trajectory of the vehicle in advance, and assists the driver to drive. The C-type boom suspension design ensures smooth operation of the vehicle.
If the skill race is a comprehensive competition of vehicle performance, then the fun race is a "cross-dimensional assessment" of the racer's level and vehicle handling performance. With the holding of the competition, Yutong New Energy Bus has performed well in terms of vehicle vision, stability, steering control and passability, and its reliability and safety have been fully verified, demonstrating the cutting-edge level and leading quality of China's new energy bus manufacturing.
Measured power consumption per kilometer 0.78 degrees!
Yutong pure electric bus electricity fee can be as low as 0.23 yuan / km
The adhesion of the ice and snow road is extremely low, which has a huge impact on the safety and stable driving of the vehicle, but Yutong New Energy Bus has delivered a satisfactory answer in cooperation with the players. However, under the extremely cold temperature, the new energy bus also faces another problem, that is, whether the performance of vehicle start, battery life, charging efficiency, vehicle energy consumption and component durability can withstand the test.
The answer is still yes.
In the endurance test race held on the same day, Yutong's 10.5-meter pure electric bus drove 25 kilometers continuously in the real comprehensive road conditions, consuming 19.5 degrees of electricity, and calculating the power consumption per kilometer was 0.78 degrees, such as the night electricity price of 0.3 yuan / kWh, the minimum electricity cost per kilometer could reach 0.23 yuan, far lower than the fuel car, which not only effectively eliminated the problem of winter endurance, created economic benefits, but also reflected the hard power of national brands and Chinese manufacturing.
For the performance of Yutong pure electric bus, the racers are also unfinished and impressed, one racer said: "During the race, the outside of the car is extremely cold - 40 ° C, the inside of the car is warm as spring, Yutong provides drivers and vehicles with 'comfortable operation' double guarantee, and the scientific and technological strength is impressive!" ”
Ice and snow challenges, who fight with the front. At present, in the northern regions such as Mohe and Harbin in China and cold areas such as Kazakhstan and Northern Europe, Yutong pure electric buses have achieved mass sales and extensive operation, becoming a beautiful scenery in the extremely cold land.
In the future, Yutong Bus will continue to keep pace with the times, carry forward the spirit of "challenging the limit, overcoming difficulties", deeply cultivate the core technology, challenge the quality limit, create a high standard, all-weather, all-regional operation of zero-emission bus products, with hard-core quality, to help the industry enter a new era of development!
