Today ’s motorists are accustomed to connecting to the Internet 24 hours a day, seven days a week to keep in touch with colleagues, employers, customers, family members and social networks. Whether buying an economy or luxury car, they want to consider the overall driving kit price, safety, performance, reliability, comfort, and "amazing" factors. Enhancing the functional characteristics of drivers and passengers can help build car brands and make car products stand out in the market.
By leveraging connector design and expertise, automakers are breaking down barriers and providing complete components in "connected" cars. From standard sealed connector systems to high-speed in-vehicle digital communication products, top automakers are using advanced electronic devices to improve vehicle efficiency while responding to market demand for "connected" vehicles that economically integrate feature-rich consumer electronics devices.
The complexity of high-speed vehicle wiring integration
Whether it is a luxury car to an economy car, more and more car manufacturers provide electronic devices that appeal to consumers in all car types. Automotive design increasingly incorporates the latest in-car audio and video infotainment, GPS navigation, driver assistance, reversing video surveillance systems, and other content-rich mobile consumer electronics devices. Electronic product manufacturers see a corresponding increase in demand for higher-speed automotive connectors, wiring, cable assemblies, switches, and other electronic technologies in order to achieve these comfort and convenience features.
However, although demand is rising, not all OEMs and designers are experts in high-speed electrical connections. Designing "connected" cars presents unique engineering design challenges, including cost, complexity, signal integrity, vehicle integration limitations, and environmental requirements. For these high-speed connections, automotive electronics platforms must meet strict design specifications and performance requirements.
In terms of component selection, the link service subsystem is the main influencing factor, as well as the location of the on-board module or device, and the performance requirements of the connector. Unlike PCs or other portable consumer devices, the life of a car can span 15 years or more, so product integrity and long life are important considerations.
To solve these problems, leading electronic product companies and engineers are increasingly adopting expertise from other industries and adapting the latest technologies for automotive applications. Advanced interconnection and high-speed technology are helping automakers meet engineering design challenges. For smarter and more connected vehicles, designers are developing scalable and flexible economic platforms, and powerful crossover technologies provide them with invaluable tools. In some cases, the most cost-effective method is to transplant or modify existing consumer electronics products to meet automotive requirements. In the field of "connected vehicles", the need for better design has inspired the industry to develop new electrical and electronic products.
Design Elements of "Connected" Automotive Engineering
A large number of user access ports, point-to-point connector components, and other network solutions for motorists and passengers have been tested and verified in demanding automotive applications, including:
• Membrane switches provide durable, lightweight and low-side high options for integrating vehicle user interfaces and electronic components. The standard membrane switch is a thin micro-moTIon component with one or more layers of silver or carbon conductor printed on the polyester base layer. Tactile membrane switches, poly-dome buttons, silicone keyboards, and tactile metal membrane buttons are available to provide "click" feedback or audible sound during switch operation.
• Use solid-state circuits to detect touch, and custom capacitive switches are designed to withstand harsh chemical environments, contaminants, and EMI, so this user interface is rugged in automotive applications.
• Driver Convenience Port (Customer Convenience Port, CCP) module optimizes the connection of power supply and high-speed audio, video display, CD player, DVD player and navigation equipment. To increase engineering design flexibility, CCP options include integrated I / O with integrated USB, SD memory card, HDMI, IEEE 1394, Ethernet, Bluetooth, and auxiliary jack media ports.
• Stac64 ™ single-hole, multi-hole (mulTI-pocket) and hybrid connector systems reduce engineering design time and time to market by providing modular housing connectors. In telematics, navigation, instrumentation and other vehicle electronics applications, the connectors are easily combined. This universal stacking connection system supports low-level signal requirements and power applications that exceed 30A.
• Standard and custom light-emitTIng diode (LED) printed circuit components that support low power consumption in high-current applications, including indicator panels, interior lighting and navigation, reflectors, side lights, headlights, emergency lights , Brake lights and parking lights.
In terms of technology trends, three major digital connections are emerging in the field of connected vehicles-consumer access points, video (port-to-port) and in-vehicle networks (peer-to-peer). Whether it is an optical fiber or copper connection solution, there are multiple options, which have been used to support high-speed digital link technology into vehicles. Many are based on Serial Deserializers (SerDes) and network standards, which can help reduce weight and provide endless possibilities for vehicle architecture changes, but not without initial challenges.
