  • Page 46: Control Functions

    CONTROL SYSTEM CONTROL FUNCTIONS Control software The functions of the E-ECU software can be divided into the following categories: 1. Driver: Interface between hardware and software 2. Diagnostics: Troubleshooting and event logging of the engine and control hardware 3. Communication: Data exchange among the checker and other E-ECU communication features 4.
  • Page 47 CONTROL SYSTEM The control program and the engine model-specific control map are maintained as prime constituents by engine models. The individual data is created per each injection pump and engine and maintained as CS data. Figure 2-12 illustrates constituents of the E-ECU data. The control program is common to all engine models and cannot be customized per customers.

    CONTROL SYSTEM General Speed sensor input The Eco-governor detects the engine speed with 12 pulsers attached to the camshaft. See Figure 2-13. Assuming that the frequency of pulses provided by the pulsers is fp [Hz], the engine speed N rpm [min ] is given by Nrpm[min...
  • Page 49 CONTROL SYSTEM Rack position sensor input The Eco-governor controls the fuel injection quantity by adjusting the rack position of the fuel injection pump. The rack position is converted into voltage by the rack position sensor, and the voltage signal is applied to E- ECU terminal RPS and sent to an AD converter.
  • Page 50 CONTROL SYSTEM A high-accuracy coolant temperature sensor will also be able to connect to terminal TFO (E16). The measurement error of the high-temperature coolant temperature sensor will be approximately ±2°C at 0 to 110°C. The high-accuracy coolant temperature sensor can double as a coolant temperature switch (121250-44901) whose measurement accuracy is required to be 110±3°C.
  • Page 51 CONTROL SYSTEM Contact input There are two schemes for contact input of the E-ECU: High-side input and Low-side input. See Figure 2-17. The contact input of the E-ECU has been designed with the same sink current and source current of 1.0 mA typ.
  • Page 52 CONTROL SYSTEM Figure 2-19 illustrates the voltage levels at the input terminal for the low-side contact input. When the switch turns on, the input terminal goes low for the switch with NO contact and goes high for the switch with NC contact. 1.2k 1.2k Contact input...
  • Page 53 CONTROL SYSTEM Rack actuator output The rack actuator output is a high-side output. See Figure 2-21. The E-ECU adjust the magnitude of current flowing through the rack actuator solenoid by shortening or lengthening the ON-duration of the output transistor. The rack position of the fuel injection pump varies depending on the magnitude of current flowing through the rack actuator.
  • Page 54 CONTROL SYSTEM Control map As already mentioned in "Control software", the E-ECU software can be divided into the control program, engine model-specific control map and individual data. This section describes the engine model-specific control map. Map data can be categorized into the following types: 1.

  • Page 55: Engine Control - General

    CONTROL SYSTEM Engine control - General Self-holding of the E-ECU power The E-ECU saves engine logs including faults and running hours in the internal EEPROM. And it has a power self-holding feature that allows the power supply to be held until the engine logs are completely saved in EEPROM.
  • Page 56 CONTROL SYSTEM Torque curve and engine regulation Standard engine torque curves are outlined in Figure 2-25. Details of the curves varies depending on the engine models. For the Eco-governor, engine regulations are available in the following variations: (a) Isochroous The engine speed is constant, regardless of the load (regulation 0%). (b) Virtual droop (torque curve of base engine) Approx.
  • Page 57 CONTROL SYSTEM Switching between "isochroous" and "virtual droop" can be done with an external switch or through CAN communication, while the engine is running. Selection of either one as default is allowed on customer's request. Switching between "isochroous" and "virtual droop" can be done even while the engine is running. "Reverse droop" can also be enabled or disabled with an external switch or through CAN communication while the engine is running.
  • Page 58 CONTROL SYSTEM Speed control The target engine speed is defined by input signals from the accelerator sensor or through CAN communication. Figure 2-28 shows the flow of defining the target engine speed. Elements and optional settings in the flow will be described later. The accelerator input selection feature allows certain accelerator sensors to be selected as input source among others depending on the setting and status of accelerator sensors.
  • Page 59 CONTROL SYSTEM Figure 2-29 shows the engine speed control block diagram. [Speed control] The deviation of the actual engine speed (Nrpm) from the target engine speed (Nset) is used to determine the target rack position (Rset) with PID control. The target rack position is the basis for providing torque limitation or rack motion delay adjustment for transition control (described later).
  • Page 60 CONTROL SYSTEM EGR control The Eco-governor uses an electronic-controlled EGR valve to reduce the emission of NOx from 37 kW or more engines. The EGR valve is driven by a stepping motor. The opening (0 - 54 steps) of the EGR valve is adjusted depending on the engine speed and load factor so as to control recirculation of exhaust gas.
  • Page 61 CONTROL SYSTEM Calculation of load factor The load factor of the engine is determined as a percentage from the rack position at idling (Ridl), maximum rack position (Rmax), minimum rack position (Rmin) and actual rack position relative to Rmin (Ract). See Figure 2-32.

  • Page 62: Application Interface Outline

    CONTROL SYSTEM Application interface outline Accelerator input selection Accelerator sensors are available in three types: standard (analog voltage), backup (analog voltage) and CAN communication (communication command) types. See Figure 2-16. Using accelerator sensor setting flags allows combined use of these sensors. In standard mapping (1), the main accelerator sensor is solely used.

  • Page 64 CONTROL SYSTEM Figure 2-34 shows the foot pedal failure detection scheme. If the input voltage from the foot pedal is out of the range of 0.2 V to 4.6 V, the E-ECU detects a sensor failure. If APP-IP2: NO goes high or APP-IP7: NC goes low while the input voltage is 1.1 V or higher, the E-ECU detects a sensor failure (depending on the status of the active switch when the flag is set to 3 or 4).

The air heater relay permits the E-ECU to check for disconnection or short-circuit. 1. ON-glow control (standard feature) When the key switch is moved to the "ON"...
  • Page 66 CONTROL SYSTEM Starter motor start prevention When the key switch is turned on, the Eco-governor performs rack self-diagnostics before starting the engine in order to ensure safety. The starter motor must therefore be prevented from starting until rack self- diagnostics is completed. Starter motor staring prevention can be implemented by connecting a starter relay to the E-ECU.

  • Page 74 CONTROL SYSTEM Accelerator filter The accelerator filter regulates the trade-off between acceleration/deceleration time and overshoot/ undershoot during acceleration or deceleration. This feature is factory set appropriately, but a higher priority may have to be given to either the reduction of acceleration/deceleration time or the suppression of overshoot/undershoot depending on the engine applications.
  • Page 75 CONTROL SYSTEM Highland compensation (pending) This feature allows the injection quantity to be controlled so that the emission of black smoke due to a low oxygen concentration is minimized in high-attitude places. By default, the highland compensation feature (pending) will be disabled. Engine failure detection The E-ECU accepts the connection of engine failure detection sensors as shown in Figure 2-51.

When two or more failures have occurred simultaneously, the failure lamp indicates all the failures in order of increasing number of flashes cyclically.
  • Page 80 CONTROL SYSTEM CAN communication The E-ECU is equipped with a CAN communication port that can be used to communicate with the service tool. The physical layer for CAN communication conforms to ISO 11898 Ver2.0B and uses 29-bit CAN arbitration ID. Baud rates of 250 kbps and 500 kbps (default) are available. The E-ECU supports communication protocols conforming to ISO 15765 and KWP 2000 for service toll and ASE J1939 for inter-E-ECU communication.
