5.1.113. UEGO sensor control — CJ125 device (pcj125_Control)

Update internal configuration of CJ125 devices.

5.1.113.1. Supported targets

M670-000

5.1.113.2. Required license

None (Main library). (See Section 2.3, “Licensed Features”.)

5.1.113.3. Description

Interface to control behaviour of a UEGO sensor via CJ125 device.

The Platform provides this interface for ECUs containing Bosch CJ125 devices to uses the device to interact with external Bosch LSU 4.9 UEGO sensors. For further information on connecting to and using UEGO sensors, please see the ECU's technical specification.

This block is called periodically during an application task to set the internal configuration of the specified CJ125 device. The block should be called in a task with the desired rate at which the device should be reconfigured.

5.1.113.4. Inports

  • calibration_mode

    Set to 0 to put the CJ125 device in normal operation mode. Set to 1 to put the device in calibration mode. This will cause the UR and UA analogue inputs for the CJ125 to be set to their calibration values.

    When calibration mode is enabled, UR, being the input indicating the temperature of the UEGO sensor, will indicate the UR measurement corresponding to the optimal UEGO sensor temperature. UA, being the input indicating the UEGO pump cell current, will be set to the value corresponding to a Lambda measurement of 1 when calibration mode enabled. See the ECU's technical specification for more details.

    Range: [0, 1]

    Value type:Integer
  • reference_current

    Set to the enumeration of the desired reference current used by the device.

    Range: [0, 15] respectively for the enumeration values: 0 uA, 10 uA, 20 uA, 30 uA, 40 uA, 50 uA, 60 uA, 70 uA, 80 uA, 90 uA, 100 uA, 110 uA, 120 uA, 130 uA, 140 uA, 150 uA

    Value type:Integer
  • Ip_amplification

    Set to the enumeration value corresponding to the desired amplification of the pump current (Ip). Ip is calculated from the UA input and its value is dependent on the specified gain setting. See the ECU's technical specification for more details.

    Range: [0, 1] respectively for the enumeration values: Gain 8, Gain 17

    Value type:Integer

5.1.113.5. Outports

None.

5.1.113.6. Mask parameters

  • Channel

    Which CJ125 device to control.

    Value type:List
    Calibratable:No
  • Initial Reference Current

    Initial value of the Reference Current.

    Value type:List
    Calibratable:No
  • Update during Runtime? (a)

    If selected then inport reference_current is made available. Otherwise the Initial Reference Current value is used during runtime.

    Value type:Boolean
    Calibratable:No
  • Initial Ip Amplification

    Initial value of Ip Amplification.

    Value type:List
    Calibratable:No
  • Update during Runtime? (b)

    If selected then inport Ip_amplification is made available. Otherwise the Initial Ip Amplification value is used during runtime.

    Value type:Boolean
    Calibratable:No

5.1.113.7. Notes

None.
