KIBES for trucks

The following is typical for truck electrics:

  • Concentration of most wiring in the driver / operator cabin.
  • Variability of harnesses due to differences in connecting alternatively offered aggregates (engines, gearboxes, retarders, etc.), special bodies and optional equipment (air-conditioning, auxiliary heating….)
  • Instrument cluster in front of the driver contains gauges, coloured lights with standardised pictograms and a central display with current values of selected quantities and diagnostic messages from the other units connected to the control system.
  • Communication with a trailer/towed unit used in a typical truck control system:



    The KIBES modules   

  • Main vehicle control unit CBCU3 / CBCU3-E
    serves as a central controller (VECU), which processes information from all sources connected to the control system.
    It is located in a protected space in the cabin.
    The CBCU contains a sufficient number of inputs and outputs for standard trucks.
    Mainly dashboard buttons, steering column switches and also sensors from the body and from devices communicating via CAN-bus are connected to the inputs (58).
    The outputs (34) have a current capacity graduated in a wide range, which enables it to control various appliances: position, turn signal and headlights, wiper motor, etc.
    If the number of the inputs/outputs is not enough or if the length of a thick wire bundle is too long (e.g. to control lights or devices at the rear of the vehicle), an input/output unit can be added. If it can be located in a protected environment, the cheaper unit MUX2-B can be used. The MUX3-P is intended to be mounted on the chassis, as this unit has good protection against environmental influences (IP67).

  • The CBCU is user-programmable in the KIBES-32development environment.
    The program provides:
    - controlling integrated inputs and outputs
    - controlling the CMIC instrument cluster via „instrument CAN“ (ICAN)
    - processing signals from the MCU control menu
    - communicating with other vehicle units connected to the „powertrain CAN“ (PCAN); 
    - communicating with MUX2-B expansion units connected to the „multiplex CAN“ (MCAN).
    - forwarding messages for devices on different CAN-buses – the „gateway“ function
     
  • Instrument cluster CMIC 
    serves to transmit current information to the driver
    It is located in front of the steering wheel.
    The CMIC contains all the elements common in modern vehicles: 
    - 2 large gauges: tachometer and speedometer
    - 4 smaller gauges: fuel supply, coolant temperature, air pressure in 1st and 2nd reservoir 
    - 23 standardised control lights: headlight and direction lights, overheating, discharging….
    - Monochromatic LCD for displaying graphic and text values
    - „Trip“ button for reset 
    - Speaker for audio indication
    Descriptions, icons and scales can be modified according to the user input.

    The control system can run also without the CMIC instrument cluster; thus it is possible to offer many equipment variants to our customers, from extremely minimised to maximised comfort.'


  • Menu driver MCU 
    usually serves to select a required function from the menu shown on the display, or for setting values: current time, speed limit… 
    The MCU is a rotary control with a button, whose application is similar to using the mouse on a desktop 
    It is located next to the instrument cluster.

    Of course, the configuration described can be used as a simpler variant of a bus control system.
