What Changxing does

Changxing (上海畅星软件有限公司) is a privately held Chinese automotive technology company founded in 1996 and headquartered in Shanghai's Pudong New Area, with wholly-owned subsidiaries SIS JAPAN (Japan, established 1992) and Taiwan Changxing Technology (established 2013). The company designs and supplies connected-vehicle technology to international automotive OEMs, operating as a Tier 1 supplier with a 'cloud-pipe-device' (云·管·端) integrated architecture spanning T-BOX telematics hardware, embedded software, intelligent cockpit systems, ADAS, navigation/V2X, and the RoadPal and TSP cloud platforms.

Its core product portfolio includes the T-BOX family of telematics control units (generations 1.0 through 5G+V2X), a Smart Cockpit System integrating DMS/OMS cabin monitoring, face recognition, HUD and multi-modal interaction, ADAS platforms covering L1-L4 autonomy, high-precision lane-level navigation powered through an authorized Amap SDK partnership, and the TSP cloud platform supporting new energy vehicle monitoring, after-sales service management, and value-added services such as scan-to-charge and in-vehicle payment. Notable technical differentiators include first-mover Android 4.0 in-vehicle intelligent terminal development (2013) and bundled multi-year free cellular communication services tied to T-BOX sales.

Changxing generates revenue through a mix of B2B hardware sales (T-BOX units and cockpit electronics to OEM production lines), custom software development and system integration services (intelligent cockpit, ADAS, connected vehicle applications), and recurring TSP platform operations, OTA upgrade services, and bundled communication traffic management for deployed fleets. Go-to-market is exclusively direct enterprise/Tier 1 OEM supply via embedded design wins with manufacturers including Honda (Tier 1 status since 2019, exclusive T-BOX supplier from 2020), Dongfeng Nissan, Renault, Infiniti, Buick, and a legacy relationship with Toyota/Lexus, supplemented by a fleet-management deployment with Japan's Yamato Transport covering 32,000 trucks. Pricing is quote-based and project-specific, not publicly disclosed.

Core offering

Changxing designs, manufactures, and integrates connected vehicle hardware and software for automotive OEMs, anchored by its T-BOX telematics control unit, intelligent cockpit system, ADAS platform, V2X/navigation technology, and TSP cloud service platform. Its products are embedded directly into OEM vehicle platforms (Honda, Nissan, Renault, Infiniti, Toyota, Lexus) and operated via recurring TSP and communication services.

Product overview

Changxing offers a cloud-pipe-end (云·管·端) integrated connected-vehicle product portfolio. The hardware layer is anchored by T-BOX (Telematics-BOX), a vehicle-mounted 4G/5G and C-V2X unit that serves as the connected-vehicle gateway. The in-vehicle experience layer is delivered through the Smart Cockpit System, integrating DMS/OMS monitoring, face recognition, HUD, and multi-modal (touch, voice, gesture) interaction. ADAS (L1–L4) provides active safety and driving assistance across front, side, and rear vehicle zones. Navigation & V2X provides high-precision lane-level navigation and vehicle-to-everything connectivity. The TSP (Telematics Service Platform) cloud layer unifies these components, offering new energy vehicle monitoring, after-sales service management, and multimedia value-added services. Changxing develops and delivers all five product lines to OEMs including Honda, Nissan, Renault, Infiniti, and SAIC-GM, spanning the full connected-vehicle value chain from hardware and embedded software to cloud platforms and mobile apps.
