Target applications

Applications that FlexRay targets as in-car LAN are described below.
These applications are in technical innovation field that draws attention of manufacturers and suppliers in terms of applications to X-by-Wire.

1. EPS: Electronics power steering
   This range of applications covers applications for computerizing the existing power steering system. This field is especially important because of its application in Steer-by-Wire technology. For example, it may enable controlling the steering angle in dependence on the motor revolution rate.
2. ABS, VSC, VSA
   ABS: Anti-lock brake system
   VSC: Vehicle stability control (Vehicle stability control system)
   VSA: Vehicle stability assist (Vehicle behavior stability control system)
   
   This range of applications covers applications for computerizing the above-mentioned brake systems. This field is especially important because of its application in Safe-by-Wire technology.
   For example, it may enable computerizing the brake pad control.
3. Steering sensor
   The module (ECU) is typically called top column module and it comprises a steering angle sensor which has been lifted to Flexray network in order to share the same bus as other X-by-wire components.
4. AT: Automatic Transmission
   AT has worked as a driving power system in conjunction with existing systems such as computerized fuel injector, computerized variable intake control system, and computerized idling control system. Besides, this application will control the electronic throttle by replacing the mechanisms of accelerator and throttle.
   This field is therefore important because of its application in Drive-by-Wire.
5. Gateway
   This application controls the replacement of signals of two different networks, FlexRay network and CAN network.
