Infotainment Systems

In addition to powertrain and chassis control systems, instrument panel is where automotive electronics exert their influence on modern cars. The dashboard applications include speedometer and tachometer, audio/video systems (radio, CD/DVD and external MP3 player, etc.), satellite navigation system and the climate control panel.

The infotainment system integrates multimedia systems, other onboard electronics and the telemetric system to access external services. The messages can be displayed on the on-board monitor or conveyed through voice prompts for the ease of use by passengers. Using simple buttons, passengers can access useful information or control other on-board electronics devices. At HAITEC, the infotainment system is named “THINK+” to reflect the “Think Ahead” concept; its design capability includes planning and design of subsystems, graphical user interface (GUI), navigation, customer support centers as well as testing and verification of the complete system.

(CAN bus) Control Area Network

Modern vehicles have become increasingly complex, and components must work in concert for the vehicles to function properly. For example, an advanced braking system can improve its performance by the Distributed Function Design (DFD) approach that reduces the driving power from the powertrain system. To realize DFD, each control unit must be able to exchange necessary information (car speed and engine RPM, etc.) with other control units through a common communication network. This network needs to meet four key requirements in vehicle applications: noise resistance, high transfer rates, error detection/tolerance and affordable cost.

The CAN (Control Area Network) bus is now the network of choice for carmakers around the world, and it is also the network backbone of the vehicles developed by HAITEC.

Vehicle electronic systems

Vehicle electronics design includes six areas: vehicle planning, system design, component design, component verification, system verification and vehicle verification. The system development process must take into consideration not only the functional requirements but also the reliability and durability of electronic systems. The overall design process consists of human factors engineering, system interface, software (hardware) development, component testing, system testing and vehicle testing. A complex verification process that checks the wiring harness, ECU simulator, weather resistance, electro-magnetic compatibility and overall vehicle characteristics must be completed to ensure the safety and quality of electronic systems.
