本文以日本汽车软件公司(ASW)为例，试图对嵌入式软件产品创新的动态化和异构性研究有所贡献。嵌入式软件的功能是通过嵌入硬件来实现的，所以如果我们知道一个嵌入式系统的功能，就知道它的嵌入式软件的功能。因此，基于利用第三国专利作为国家创新活动的良好替代指标的优势，我们使用USPTO专利数据库中与ASW相关的专利作为ASW产品创新的指标。结果表明，从1981年到2010年，不同的行为者在ASW功能的几个领域有不同的作用和创新倾向，即动力总成控制、电池和电力控制、安全控制、车身控制和信息和通信技术系统。这种转变始于20世纪90年代初，当时供应商在ASW的产品创新中变得越来越重要。越来越多的合作主要发生在汽车制造商和供应商之间，特别是大供应商之间。综上所述，嵌入式软件产品创新异构性的主要原因是对实时操作的异构性需求和对特定知识的积累，这些要求具有技术难度和复杂性。
This paper tries to contribute to the research on dynamics and heterogeneity of product innovation in embedded software in the case of Japanese automotive software (ASW). Functions of embedded software are realized by being embedded into hardware, so if we know the functions of an embedded system, we know the functions of its embedded software. Therefore, based on the advantage of using patenting in large third countries as a good proxy measure for national innovation activities, we use ASW related patents in the USPTO patent database as an indicator of ASW product innovation. The results show that heterogeneous actors have had different roles and propensities to innovate in several fields of ASW functions, namely power train control, battery and electric power control, safety control, body control and ICT system over the period 1981 to 2010. There was a shift beginning in the early 1990s when suppliers were becoming more and more important in product innovation of ASW. Increasing cooperation happened mainly between the automotive makers and suppliers, especially big suppliers. To conclude, the heterogeneous requirements for real-time operation and accumulation of specific knowledge that are technologically difficult and complex are the main reasons of heterogeneity of product innovation in embedded software.
