Overview

Traton CM4 is an advanced telematic and connectivity module. It is capable of performing advanced wireless communication and at the same time to interface with other ECUs or devices available on the truck. Defined customers for the Traton CM4 project are MAN and Scania. For both customers, a single HW design is developed, but the component population on the production line will be different based on the variant. The development of the HW platform and the basic platform SW is under Continental’s responsibility. The development of the application SW is under Traton’s responsibility.

Vehicle mountingThe 
CM4 device will be mounted inside the vehicle cabin in a dedicated location. For Scania vehicles, the CM4 device will not be directly visible to the driver, while for MAN vehicles, the CM4 will be directly visible to the driver. The initial step for mounting the de device is to plug the associated harnesses according to the connectors mapping presented below,Continental-Communication-Module-fig-1

Main connector pinoutContinental-Communication-Module-fig-2After the connection of the associated harnesses, the device will have to be installed according to the specific procedure (procedure developed by the customer for its specific version)

Interfaces

Interfaces with other ECUs/devices in the vehicle
Interfaces with other ECUs/modules available in the vehicle are dependent on variants.

MAN-specific interfaces

  • Power supply lines (TRM 30 and TRM31)
  • Terminal 15 input indicating vehicle ignition signal;
  • Ethernet communication interface – 1 channel with 100 Mbps;
  • 3 CAN nodes with frequency up to 500 KHz;
  • USB communication interface – Used only during device production, will be deactivated during actual operation. This interface will not be used during the operational lifetime, but only during the production test.
  • 2 generic digital input signals;
  • 2 generic digital output signals;
  • 1 digital input for enabling DoIP(via SW);;
  • 1 indicator LED

Scania specific interfaces

  • Power supply lines (TRM 30 and TRM 31)
  • Terminal 15 input indicating vehicle ignition signal;
  • Ethernet communication interface – 1 channel with 100 Mbps;
  • 2 CAN nodes with frequency up to 500 KHz;
  • USB communication interface – this interface will not be used during the production lifetime, but only during the production test.
  • 1-wire bus communication interface for interfacing with an external iButton
  • 2 digital input signals;
  • 2 digital output signals;
  • 2 digital inputs/outputs signals

RF communication interfaces
RF communication interfaces supported by Traton CM4 are:

  • Cellular communication
  • WIFI communication
  • BT communication
  • GNSS signal acquisition

These RF communication protocols are supported on all variants.

Expected behaviour

After the supply voltage has been applied (KL30 set to 24V or 12V), the CM4 device starts booting up. The bootup process takes about 90 seconds. Some functionalities, like CAN communication, ETH communication, are available before the bootup process ends, but the full functionality is reached only when the boot-up process is finished.

Main functionalities provided by the CM4 device

  • GNSS positioning (starts automatically after boot-up phase)
  • Communication with the back office via cellular network (triggered by customer application or test application)
  • Communication over WIFI (triggered by customer application or test application)
  • Communication over BT (triggered by customer application or test application)
  • Communication via CAN based on the database received from the customer;
  • TCP communication via Ethernet;

There is no functional difference between the 12V CM4 systems and 24V CM4 systems – a single HW design covers the full voltage functional range.

Restrictions
Assembly or disassembly of the TRATON CM4 while the operating voltage is connected is not allowed. Assembly or disassembly of connectors while the operating voltage is connected is not allowed.
