5. Key parameters of the product

According to the research results of the market and customers, the key attributes of the product are set. Generally, the key parameters of the product are analyzed from the latitude of vehicle size, power type, chassis type, intelligence (including software) and performance.

(1) Car grid size The car grid size is related to the market segment and brand positioning of the product, and is an important parameter to be considered in the product planning stage. Wheelbase and wheelbase are significant factors affecting the size of the vehicle grid. The wheelbase is set as an adjustable parameter of the platform to realize the expansion of the vehicle length of the platform. On the same subdivision platform, the expansion range of the wheelbase is generally set at 200-300mm ; Wheelbase is an important factor affecting vehicle width, but its expandable bandwidth range is small, generally 50-100mm. Other grid dimensions, such as ground clearance, front overhang length, rear overhang length, etc., should be considered as required. For specific methods, refer to the relevant chapters of general layout.

(2) Power type Common types of power vehicles include fuel vehicles, hybrid electric vehicles (Hybrid Electric Vehicle, HEV), plug-in hybrid electric vehicles (Plug-in Hybrid Electric Vehicle, PHEV) and pure electric vehicles (Electric Vehicle , EV) etc. When planning platform products, the power type of the product must be compatible with the same platform. For fuel oil platforms, the compatible engine displacement is usually limited. Therefore, when planning platform products, it is necessary to pay attention to the types of engine displacements of products on the same platform.

(3) Chassis type Chassis mainly includes suspension system, braking system, steering system and transmission system. Among them, the suspension system has the greatest impact on the platform, so in the product planning stage, the suspension type needs to be considered according to the product's competitive strategy. Common front suspensions include MacPherson, multi-link, double wishbone and other structural forms, and common rear suspension types include torsion beam, multi-link and other structural forms.

(4) Intelligence (including software) The intelligent part includes four parts: electronic and electrical architecture, vehicle operating system, application program, big data and cloud service. The electronic and electrical architecture is the basis of the intelligent hardware of the vehicle. The vehicle operating system plus application programs form the basic software platform of the vehicle. Big data and cloud services can continuously improve customer experience on the basis of unchanged hardware. In the product planning stage, it is necessary to clarify the intelligent requirements of the product in order to plan the intelligent platform architecture and software layout of the product.

(5) When planning performance products, usually from power, economy (fuel consumption or power consumption), posture, safety, comfort, handling, intelligent driving, intelligent cockpit and over-the-air (OTA) upgrades Technology and other dimensions of customer concern are used to plan product performance.
