Shanghai June 3, 2021 / US News Society / – Software can bring the consumer’s new car experience through continuous iterative upgrade, and also require automobile companies to control the software quality throughout the consumer. This is a problem that every automotive company needs to respond to the full life cycle of the car. In this regard, JD Power has released a view of “Intelligent Net Software Quality Management System Based on Scene”.
Software Defining Car User Experience
With the evolution of automobile intelligence, the definition of the car is changed, the future car is no longer just a means of transport, but will Like computers, mobile phones, becoming one of the most close intelligent terminals with consumers, with mass storage and high-speed computing capabilities to meet human digital individual needs.
An important factor in supporting this transformation is software capabilities. The essence of software defined cars is to achieve the flexibility of vehicle functions and user experience through software, through software update, bringing new human-computer interaction and functional experience through software updates, and extending to different digital scenes, creating new consumption patterns . From this perspective, the software redefines the intelligent user experience of the car.
How to deal with the software quality of more than 100 million lines of code?
Data show that a typical new listing is about 100 million software code, and the formation of stark contrast is that Microsoft’s Windows operating system has only 50 million lines of code, and there are more auto industry. The software code of a fully automatic driving vehicle will rise to 500 million lines. [1] This gives today’s automotive industry a unprecedented problem – how to deal with the software quality of more than 100 million lines of code? Automotive industry with a hundred years of manufacturing history has already have a very well-established and high-standard hardware component quality management system and processes, but in the face of new features of the suncell, how to manage these “soft parts” is a company. The new topic must be facing, the current software user experience index system and software quality management have just started.

According to ISO / IEC 25010 system and software quality standard definition, software quality is divided into product quality and quality of use. In the quality of use, not only contain basic functions and non-functional features, such as functional (effective, useful), efficiency (performance), security, etc., but also allow users to get pleasure in the process of using software products; Products should not bring users with economic, health and environments; and deal with the contextual relationship of the business, cover the full business area.
Because software use quality is closely related to the use scenarios of users’ daily manifest, software quality process and systemization should be designed based on user experience journey and experience scenarios, and automotive software is no exception. Compared to the evaluation of the components of the vehicle, establish a software quality management system for the user, which can better find the key factors that drive their joy and unsatisfactory evaluation from the user’s perspective, thereby reducing the complaints of users.

In addition, the software system of the smart network car starts iteration from the product design phase, and needs to be upgraded and improved with the entire life cycle of the car, based on the actual journey experience of consumers to establish a complete set of integrity The user experience quality assurance system is critical. 
Based on the user’s journey and the use scenario,
establishes a software user experience index system and quality check
In the future, the quality of automobile software will become one of the core competitiveness of the vehicle enterprise. . To this end, car companies need to establish a set of scientific, perfect software user experience indicators and quality management systems and processes.
Building this core competitive first needs to design software experience indicators, including the evaluation dimension of the user experience, the experience indicator framework of the software system and the layers of the experience indicator. When the product meets the needs of users and is easy to use, it has gradually generated a sense of trust, which is often used, and the user can sense value.
Intelligent network user perceived value model
Second, the vehicle enterprise needs to make clear User uses the experience metrics to formulate the actual use scenario, user journey scene contacts, and analysis of user-perceived quality when making metrics.
A measurement standard should fully consider the scene contacts of the user’s journey and analysis of user perceived quality
[ 123]
Next is software quality and verification, including establishing a software quality specification, formulating software quality assignment methods, and clarifying software quality assurance processes.
Finally, the car enterprise should also incorporate the software quality management process into the software full life cycle, including the quality control of the product design initial phase, stage quality control and the periodicity of the listing product software iteration in the production process. Quality control, only this can support the full life cycle of the car travel while improving the user experience.
