Infotainment system design and development
Automotive electronics are not only used in the power and chassis but also the instrument panel. This includes the dashboard (showing engine RPM and vehicle speed), audio-video system (media related devices such as radio, CD/DVD, external MP3 player etc.), the satellite navigation system and the climate control panel.
The infotainment system integrates the multimedia system, other onboard electronics as well as telematics used for external communication and services. These can all be displayed on the same screen or conveyed through voice prompts for the consumer's convenience. Consumers can use simple buttons to access the information they need or control other onboard electronics. All car manufacturers have their own name for their infotainment system and at HAITEC, this is named "THINK+" to represent the "Think Ahead" concept. HAITEC's infotainment system design process includes system planning & design, graphical user interface (GUI) planning and design, navigation system design, customer support center and infotainment system testing & verification.
Control Area Network (CAN bus) design and development
Modern vehicles have become increasingly complex, and multiple components must work in concert for the vehicle to operate properly. For example, the advanced braking system must use a Distributed Function Design (DFD) approach with the engine/transmission system reducing the power output at the same time for optimal braking effort. To realize DFD each controller unit must be able to exchange necessary information (car speed, engine RPM etc.,) through a common communications backbone while satisfying four key requirements: noise resistance, fast transfer rates, error detection and affordability.
The CAN (Control Area Network) bus is now the technology of choice for carmakers around the world, and this was used as the network backbone of the vehicle electronics platform developed by HAITEC.
Vehicle electronics system design and development
Vehicle electronics design includes six areas: vehicle planning, system design, part design, part verification, system verification and vehicle verification. The design and verification process must take into consideration not only the functional requirements but also the reliability and durability of the electrical system into account as well. The overall design process consists of human-factor engineering -> system interface -> software (hardware) development -> component testing -> system testing -> vehicle testing. A complex verification process that checks the wiring, ECU simulator, weather resistance, electro-magnetic compatibility and overall vehicle characteristics must be completed to ensure the safety and quality of the electronics system before start of production(SOP).
