+车辆设计方案 v2.0
+
+一、车身结构设计
+
+车身采用高强度钢铝混合结构，A柱和B柱使用热成型钢板，厚度2.5mm。车顶结构设计满足GB 26112-2010抗压强度要求，正面碰撞能量吸收区域采用渐进式变形设计，确保碰撞时能量有效分散。
+
+车身侧面采用铝合金板材，减轻整车重量约15%。底盘结构采用模块化设计，便于后续维修和零部件更换。车门内部设置防撞梁，提升侧面碰撞安全性。
+
+二、动力系统配置
+
+搭载永磁同步电机，最大功率150kW，峰值扭矩310Nm。电池组采用三元锂离子电池，容量75kWh，能量密度180Wh/kg。充电接口支持快充（30分钟充至80%）和慢充（8小时充满），符合GB/T 18487.1-2015标准。
+
+电机控制器采用水冷散热系统，工作温度范围-30℃至60℃。电池包内置BMS管理系统，实时监控电池状态，具备过充、过放、过温等多重保护功能。
+
+三、安全配置设计
+
+配备6个安全气囊（前排双气囊、侧气囊、侧气帘），采用预紧式安全带。ABS系统采用博世第9代ESP，具备碰撞预警功能（FCW）和自动紧急制动（AEB）。方向盘集成驾驶员疲劳监测摄像头。
+
+安全带预紧器在碰撞发生前0.1秒自动收紧，配合气囊提供最佳保护效果。AEB系统在城市工况下可有效避免85%以上的碰撞事故。疲劳监测系统通过面部特征识别，实时提醒驾驶员注意休息。
+
+四、车身外观设计
+
+车身尺寸：长4650mm，宽1850mm，高1450mm，轴距2800mm。前大灯采用LED矩阵式设计，具备自适应远近光切换功能。尾灯采用贯穿式设计，提升视觉辨识度。
+
+五、内饰设计方案
+
+驾驶舱采用环抱式设计，中控台配备12.3英寸触摸屏。仪表盘采用全液晶显示，支持多种主题切换。座椅采用真皮包裹，具备8向电动调节和加热通风功能。
+
+方向盘采用三辐式设计，集成多功能控制按键。车内氛围灯采用可调色设计，支持256色自定义。音响系统配备12扬声器，支持环绕声效果。
