Embedded System: Single-Chip Microcomputer (Microcontrollers, Mcus)
Embedded System: Single-chip Microcomputer (Microcontrollers, MCUs) z Embedded Systems are specialized or dedicated computers used to control appliances, devices and machines z Platforms that use embedded systems include consumer appliances, IT devices and industrial/commercial machines z Consumer: PDAs, game consoles, set top boxes, automotive control systems, home appliances z IT: Printers, copiers, faxes, teller machines, telecom switches and routers, modems, videoconferencing, disk controllers z Industrial/commercial: robotics, data acquisition, manufacturing control, process control, medical imaging and monitoring, aerospace, satellite systems, radar systems Steer-by-wire: a next-generation steering system in which there is no mechanical link between the vehicle's steering wheel and the front-wheel directional actuator. A “steer-by-wire” system has only electrical signal connection between the steering wheel sub-system and the steering power sub-systems. This approach has both advantages and disadvantages compared to conventional steering systems. Steer-by-wire advantages: - Modular steering sub-system design, simplifies the assembly, lower manufacturing cost - Software customizable to fit different machine needs - The injury risk caused by the steering column being thrust toward the driver in an accident will be diminished. - Interference with the driver during stability control and automatic steering can be avoided. The main disadvantage of SBW system: there is no direct mechanical feedback to the operator about the steering conditions, which must be emulated by an active control system. Other automobile applications include: • entertainment system • theft deterrent systems • climate control • dashboard display • traction control • navigation systems Electronic components and software will, to a large extent, shape tomorrow‘s vehicles (90% of vehicle innovations).
