“Tough Gear”and “High Quality” for New X-TRAIL - 4. Application of e-4ORCE to Full-Scale SUVsRyota SuzukiFig. 10 Comparison of mogul road driving performanceTakeji Katakura4. Conclusion ReferencesThe top-row graphs show the accelerator pedal strokes. In the previous X-TRAIL model, the accelerator pedal was turned on/off each time the car ran over uneven road surfaces. The new X-TRAIL model allows running by simply changing the amount of depression of the accelerator pedal. The bottom graphs show the tire-slip and traction control states. In the previous model (ICE + mechanical AWD), TCS (traction control) intervenes every time the tire spins to limit the engine torque; however, in the new model (e-POWER + e-4ORCE), the tire spin is appropriately controlled so that there is no need for traction control intervention. This enables continuous, powerful driving without unintended drive-force limitations.The 100% electrically driven e-POWER system and the front/rear motor AWD control system e-4ORCE installed in the new X-TRAIL achieved a high level of ease of driving operation, comfort, and sense of security in each driving scene, which is expected for SUV applications. The responsive driving, comfortable ride, and sense of security, regardless of the road surface described in this study can be experienced in a wide range of situations, from everyday use to leisure, regardless of weather, climate, and other conditions.We hope that more customers will enjoy the new electric AWD-equipped full-scale SUV provided by Nissan.（1） 平工 良三、ほか：特集２-成長するe-POWER_6. 価値を高める電動AWD技術、日産技報No.87（2021）（2） 富樫 寛之、ほか：特集２-次世代のフラッグシップARIYA_7. 日産が考える電動AWDの進化「e-4ORCE」、日産技報No.88 （2022）（3） 町田 直也、ほか：ドライビングシミュレータとCAEを用いた電動AWD車加減速挙動設計手法の開発、自動車技術会2022春季大会24Authors
