车载光学市场跟踪：乘用车销售同比-43.4%，新能源车同比+44.6%，保持增势；丰田子公司开发纯视觉自动驾驶方案；Mobileye和集度汽车先后发布冗余传感方案。

目前电动车电池包下壳体材质基本以铝合金材料为主，工艺上包括冲压铝板焊接、整体铸造等工艺。整体压铸的电池包壳体可以实现一体成型，能灵活的进行结构和壁厚设计，实现集成电池包壳体侧壁吊耳、冷却通道等优势。但纯电动汽车电池包壳体属于大型薄壁铝合金件，对压铸工艺要求较高，需要一次性较大规模的模具和大吨位压铸机投入。

Countries such as Germany, China, and the US are at the forefront of regulating commercial deployment of L4 vehicles by 2022, including both autonomous cars and shuttles for passengers.

在特斯拉示范效应下，“软件定义汽车”已经逐渐成为业界共识，自动驾驶技术的商业化落地逐渐加速。智行者是国内自动驾驶行业领先公司，立足于无人驾驶大脑的研发及场景落地，截至 2021 年，其无人驾驶大脑已成功迭代 3 个版本。公司的无人大脑产品在环卫、物流、Robotaxi、RoboBus 等诸多场景实现落地，为 T3 出行配套的百台 Robotaxi 订单也已完成交付。

5月28日，第26届粤港澳大湾区国际汽车博览会在深圳福田开幕。本届车展以“先行向未来”为主题，展览面积达13万平方米，约100个汽车品牌的千款新车集中亮相，其中包括全球首发、亚洲首发、全国首发和首展车型50余款。从展会规模来看，大湾区车展并不及北上广成车展，而由于其更聚焦新能源及智能汽车，新能源车参展规模相对庞大；从参展人次来看，单日人次也有差距。但由于疫情影响，4月北京车展延期，大湾区车展成为今年国内首场大型车展，车企参与度和公众影响力有望超越往年。

2022 年5 月31 日，工信部出台《关于开展2022 新能源汽车下乡活动的通知》，在部分中西部省份三四线城市以及县区举办巡演的宣传活动，鼓励企业积极参与线上线下促销，鼓励地方政府积极出台刺激补贴政策加大活动优惠力度，通过适当的舆论引导进一步助力新能源汽车在三四线城市的市场接受度。此外，财政部出台《关于减征部分乘用车车辆购置税的公告》，指出对购置日期在2022 年6 月1 日至2022年12 月31 日期间内且单车价格（不含增值税）不超过30 万元的2.0 升及以下排量乘用车，减半征收车辆购置税。

Transmission is a component inside the vehicle, which is installed to transfer mechanical power from the engine for spinning the wheels. Electric vehicles are generally installed with single-speed transmission. However, leading players in the electric vehicle (EV) transmission market are launching new multi speed transmission with added features for high performance and efficient energy conversion. Electric vehicles with multi-speed transmission offer better performance than single-speed transmission systems in terms of faster acceleration, top speed, gradeability with driving range, and others.

Though not officially recognised by SAE under SAE levels of autonomous driving, L2+ is a new level of autonomy, adopted by the automotive industry, which bridges the capability and requirements gap between Level 2 and Level 3 automated driving. Over the next few years, L2+ is expected to enjoy a larger market share than L2 and L3 have. The higher adoption of L2+ will provide a larger number of consumers, with access to and acceptance of automated driving systems.
