Keep ahead and do it in practice —— Decoding the ＂Jiangsu Model＂ of the three-year reform of state-owned enterprises

　　Recently, the Haval brand brought all its new energy vehicles such as Haval Xiaolong MAX, Haval Xiaolong and Haval second-generation big dog PHEV to the Shanghai Auto Show. As a brand-new product sequence of Haval brand, Haval Xiaolong MAX is called "epoch-making" by Great Wall Motor.

　　The confidence of Great Wall Motor comes from one of its core technologies-the new intelligent four-wheel drive electric hybrid technology Hi4. It is understood that H(Hybrid) in Hi4 stands for hybrid, i(intelligent) stands for intelligence, and 4(4WD) stands for four-wheel drive system. Haval said that Hi4 will break the traditional perception that new energy vehicles have no control and provide high-class driving pleasure for new energy users.

　　According to Great Wall Motor, Hi4 adopts a hybrid "new configuration" with three power sources and two shafts, and realizes the electric hybrid architecture of series-parallel four-wheel drive through the distributed arrangement of front and rear axles and two motors. At the same time, relying on the high-precision perception of motor rotation on vehicle speed, i4′ s iTVC intelligent torque vector control system can quickly distribute and dynamically adjust the torque of front and rear axles through millisecond frequency, effectively restrain the skid of low-attached roads and the tendency of understeer or oversteer when cornering, and improve the handling stability and driving safety. In addition, Hi4′ s electromechanical coupling transmission system innovatively designed a two-gear electromechanical coupling unit, which realized the working condition coverage of engine direct drive near full speed range and met the driving needs of users in the whole scene.

　　What is more attractive is that Hi4 can reduce the cost, replace two-wheel drive products, and realize "four-wheel drive experience, two-wheel drive price, four-wheel drive performance and two-wheel drive energy consumption".

　　In addition, Haval Xiaolong MAX adopts a 1.5L hybrid engine, with a comprehensive power of 205kW, a comprehensive torque of 585N·m, a comprehensive fuel consumption of WLTC of 1.78L/100km, and a zero acceleration of only 6.8s s..

　　In the era of new energy vehicles, intelligence is naturally standard. According to reports, Haval Xiaolong MAX is equipped with a new generation of Coffee OS intelligent cockpit system, covering 12 fields such as vehicle control, system setting, navigation, multimedia and air conditioning, with a wake-up speed of 300 milliseconds, a response speed of 400 milliseconds and a vehicle control skill response of 900 milliseconds. Moreover, the coffee intelligent driving system assembled in the new model can realize L2+ level intelligent driving assistance in all road conditions, all time and all weather with one ADAS intelligent forward-looking camera, five millimeter-wave radars, four panoramic cameras and 12 ultrasonic radars, including the functions of changing lanes, intelligent cornering and intelligent dodge in HWA non-single high-speed scenes.

　　In Haval’s view, the new intelligent four-wheel drive electric hybrid technology Hi4 is very competitive, which will help Haval return to the global automobile mainstream market and win the breakthrough battle of new energy in the second half. At the same time, Hi4 will make users "affordable, drive well, save money and run far" by replacing two-wheel drive products with equivalent value, with "four-wheel drive experience, two-wheel drive price, four-wheel drive performance and two-wheel drive energy consumption".
