Bowden Wire: A bowden wire is a type of flexible cable used to transmit mechanical force or energy by the movement of an inner cable (most commonly of steel or stainless steel) relative to a hollow outer cable housing. The housing is generally of composite construction, consisting of a helicalsteel wire, often coated with plastic, and with a plastic outer sheath. 1.6. Alternatives ALT1: Hire a professional driver ALT2: Use GPS and combine with RADAR system. ALT3: Create an Automatic Cruise Control System that can do automation to drive a car more comfortable but safe. 1.7.

2.1 System Mission Phase 2 SM1: The system should make the driving more convenience. SM2: The system should make driving of the car safer. 2.2 Select development alternative ALT1: Hire a professional driver Driver is also a human, still possible to makes mistake when he is not concentrate. ALT2: Use GPS and combine with RADAR system. Socket Bluetooth GPS: Around 300 Euro and RADAR system around 200 Euro. This alternative is quite cheap but only covers SC3. ALT3: Create an Automatic Cruise Control (CCS) System that can do automation to drive a car more comfortable but safe. CCS prices only 300 Euro. If CCS combined with RADAR system it’s equal to 500 Euro. With the same price as ALT2 this system has more advantages (cover SC1, SC2, SC3, SC4). Therefore, ALT3 has chosen as development alternative. 2.3 New Context Diagram Page 5
