Chapter 1 General Information
VCU Introduction
Vehicle Control Unit, or VCU, is the master controller for an electric or hybrid vehicle.
VCU receives the sensors and driver input signals, including pedal inputs, vehicle speed signals,
and other inputs, manages the system energy, commands the driver demanded torque to
powertrain, coordinates vehicle components, achieves fault diagnose and determines the overall
vehicle drivability.
VCU plays a critical and supervisory role in the vehicle control network, or CAN bus-based network.
VCU Features
ISO26262 Oriented Design ASIL-D Safety Level
EV2274A has NXP 5744 automotive level microcontroller on board. NXP 5744 is built around a safety concept based on delayed lock step mechanism, targeting an ISO26262 ASIL-D integrity level.
*Please refer to NXP official file Safety Manual for MPC5744P
Basic Software (BSW) Ecotrons VCU comes with the basic/low-level software, supporting all typical input/output drivers for vehicle controls.
Model Based Design Production Code Generation Tool
The BSW is encapsulated as Simulink library block sets, called “EcoCoder”. Users could take advantage of the model-based design to quickly build control strategy within Simulink. With one-click in Simulink, you can get the executable code and A2L description file.
CAN Bus-Based Programming EcoFlash is a CAN bus-based programming tool. Users could re-program the executable into VCU conveniently.

Chapter 4 Function Description and Application Note
Power
VCU Power
Example Diagram
Always connect all available power supply pins to allow maximum current capability, because each 12V power pin only allows limited current through. To avoid current overload on certain pins, and to avoid the potential damage, all power pins should be connected even they seem to be redundant.
The total current through VCU is as maximum 15A.
Analog input channel AI28 is internally connected to BATT for VCU power supply voltage measurement. Its input voltage range is 0-36V with 12 bits resolution.
‘Read ADC Volt’ block in EcoCoder could help read voltage of BATT, please refer to ‘0-36V Analog Voltage Input’ part of section 4.2.2 for block setting details.

Sensor Power Supply
Example Diagram
EV2274A provides five channels of 5V sensor power supply.
5V sensor ground is common grounded internally with VCU power ground.
Sensor ground should connect to VCU signal ground instead of vehicle chassis ground.

VPWR Control Logic
With BATT connected, VCU Power (VPWR) could be activated by KEYON, DI21, DI22, CAN Wake and Power Delay signal.
Power Delay signal is controlled by the low level software and it is used for VCU power-down delay. This delay function provides the power to the VCU for an extended time window after the user turning off the key-switch. During this extended time, or “after-run”, VCU could do some “house-keeping” work, such as storing the critical data into non-volatile memory (NVM).
CAN Wake is a wake-up signal controlled by corresponding communication bus driver. The driver constantly monitors CAN bus and would activate VPWR when there is traffic detected on the bus.
KEYON, DI21, DI22 are wake-up inputs with actual pins on the VCU connector, KEYON is a typical key switch input and DI21 and DI22 are digital inputs. They are active-high and could be used as wake-up signal inputs for some applications that need to wake up VCU. For example, to wake up vehicle when charger detected.
The user application software shall, before initiating the VCU shutdown process, make sure all the wake-up signals mentioned above are not keeping the VCU awake:
• DI21/DI22 and KEYON all need to be low-asserted. • Make sure there is no traffic on CAN bus.
Notice: It is recommended to connect KEYON (Pin 59) to the actual vehicle key switch and use the “Power Management Example” block to manage the VCU and vehicle shutdown process. Proved power management strategies are integrated in that block.

Communication Module
VCU CAN Module Introduction
This VCU provides 3 CAN channels– CAN A, CAN B, CAN C, all of the CAN channels are CAN 2.0B high speed type.
CAN A, CAN C have built-in 120Ω terminal resistors, while there is no terminal resistor on CAN B.
CAN A and CAN B support VCU wake-up function, the VCU could be woken up by any messages on CAN A and messages with user specified ID on CAN B. For example, after the KEYON goes to low, which initiates the VCU to sleep, the VCU will be woken up as soon as there are messages on CAN A. This function could be used for situation where VCU need to be turned on for certain applications, such as vehicle charging.
The power supply of LSOs and HSOs can be controlled by EcoCoder block ‘Power Control Output’. The boolean input signal to the block determines whether LSOs and HSOs receive power.

CAN Implementation Layers
(1) Driver layer: the data link layer of communication model, including the IO driver and CAN drive
of the microcontroller.
(2) Abstraction layer: the network layer of communication model. It is responsible for choosing
corresponding IOs, providing CAN channel initialization, CAN sender/receiver interface for the
service layer.
(3) Service layer: the interactive layer of communication model. The implementation of this layer
is based on the interface function provided by the abstraction layer and achieved with the
Simulink model and s-function.
(4) Application layer: with DBC file and customer’s Simulink model, specific CAN communication
setup based on user-defined parameters could be implemented in this layer.

DBC File Import
The implementation of CAN messages in the application software can utilize the DBC file which
specifies formats and scaling of the CAN messages and signals already. In many cases, the DBC
file is existing and full of CAN signals, and it saves a lot of work for users simply import the DBC
file into the Simulink models, and populate the CAN messages. Ecotrons provides a convenient
way to convert the “.DBC” file to “.M” file and then populate the Simulink models. The procedure
is shown as below:

28
CCP Protocol Implementation
CCP service, DAQ definition and storage page configuration are implemented in low level
software; while the station address, DTO ID, CRO ID and other basic parameters can be configured
in the s-function.
Ecotrons VCU supports CCP-based online calibration, the VCU is compatible with EcoCAL, the
Ecotrons’ own calibration software, and other CCP-based calibration software such as INCA.
For more information about our calibration software EcoCAL, please refer to the EcoCAL User’s
Manual.

Safety Monitoring Module
In EV2274A, the checker core and the fault collection and control unit (FCCU) in the main
microcontroller NXP MPC5744P, together with the Fail-safe Machine in SBC FS6500, establish a
master-slave architecture to realize the safety monitoring function.
The safety monitoring function could be abstracted as a 3-level structure, as shown in the
picture below.
Level 1: Vehicle control functions, including all vehicle control strategies and fault diagnosis.
Level 2: Monitoring level 1 by a redundancy design, level 2 is independent to the Level 1. If there
is discrepancy between level 2 and the level 1, level 2 will force the critical safety reaction, such
as setting the torque command to ‘Neutral’.
Level 3: Low level monitoring of the software and hardware. CPU0 and CPU1 will constantly cross-
check each other, if the check fails, it will shut of the actuator/outputs, and avoid hazard situations.
EV2274A Datasheet_V1.3

After VCU received the all the inputs, the input data would be sent to both level 1 and level 2
at the same time, level 1 would send the processed results to level 2, those results would be
verified in level 2 and if the verification in level 2 fails, the VCU would cut off the outputs.
The main controller is responsible for level 1 and level 2, plus the memory (RAM) monitoring.
Whatever process being executed by the main controller will be running in the checker core at
the same time and two chips crosscheck each other constantly. When the crosscheck between
the checker core and the main controller indicates a faulty result, the FCCU fault mitigation
strategy will be triggered, and the fault will be reported to SBC chip at the same time, through
FCCU_F[0] and FCCU_F[1], and SBC will cut off the VCU output

There are two parts of software inside the microcontroller,, application software (ASW) and basic software (BSW). BSW is also called “low level software”, and it is preloaded into microcontroller by VCU manufacturer. ASW is usually created by the customer in Simulink environment and programmed to VCU via CAN bus tool EcoFlash.
BSW consist of three sub layers: • Service layer includes system service, memory service and communication service. This layer encapsulates all basic software functions into different service which would be directly called by command in application software. • ECU* abstraction layer encapsulates drivers of microprocessor and peripherals. Then, software and ECU hardware are separated. • Microprocessor and peripheral driver layer include drivers of microprocessor and peripherals. Typically, microprocessor includes driver of watchdog, timer, SPI, LIN, CAN, ADC, PWM and Flash. Peripheral includes drivers of HSO, LSO, and power management chip and CAN transceiver.
Notice: ECU stands for electronic control unit. VCU is a kind of ECU.
