Control area network

For bus systems there are several standard or quasi-standard bus structures available. For high-speed connection you can use the popular automotive CAN bus (control area network) or the SPI interface (serial peripheral interface) often used to connect the sensor to the microcontroller inside the control unit For lower speeds the LIN bus (local interconnect network) is available. In both cases a microcontroller inside the sensor unit is necessary, which works with a stable quartz clock frequency. 

The following figures show the sensor module with sensor element and evaluation electronics, as well as the complete sensor in a plastic housing with additional microcontroller and CAN (control area network) interface (Fig. 7.2.10, Fig. 7.2.11). 

Electronic control systems such as ESP, EPS, ABC, ECD, ACC, and navigation systems need steering-angle data as part of the information available on the vehicle network (CAN = control area network). Some ESP system suppliers and car manufacturers require an SAS to fulfill safety requirements. Fig. 7.11.2 shows a modular approach around an SAS core technology.

The front plate contains connectors for the TPIM, OBCM and APM modules, additionally two signal connectors for the controller area network bus (CAN bus) tind the 12-V power supply. On top of the battery housing, a socket for the manual service disconnect (MSD) is positioned. The MSD plug contains the main fuse of the system. All external connections of the battery system are equipped with contacts for the high-voltage interlock loop. Pulling a connector or the MSD will cause the contactors to open in order to prevent arcing.

Interface). The former tends to be used where high levels of functionality and data rates are needed whereas the latter, which is based on the controller area network (CAN) protocol, is used in applications where there are lower functionality and simple input/output requirements. The manufacturers of these fieldbus systems have worked on developing them for use in safety applications, mainly to incorporate appropriate levels of fault tolerance or safety integrity. This has led to the availability of the Profisafe and AS-Isafe fieldbuses. In addition, PILZ has developed the SafetyBUS fieldbus for safety applications, which is again based on the CAN protocol, and the Open Devicenet Vendors Association has developed a safety version of the DeviceNet fieldbus called DeviceNet Safety. 

Controller reads this pedal signal and places a corresponding torque demand on the High Voltage Power Inverter (HVPI) via the Controller Area Network (CAN)... 

The processing systems of modem robotic systems are usually distributed, which requires a shared memory or adatacommunication network between the processing units to ensure adequate time constraints for message transmission. A data commimication network that has this ability to communicate in real time is a CAN (Control Area Network).
