Overview

The uReader system allows, safely and without altering the vehicle manufacturer's warranty, reading real time data of the CANbus. In a easy and standardized way information is obtained without the vehicle manufacturer FMS Interface. The uReader system sends all FMS standard SPNs and additionally the J1939, whenever they are available on the vehicle.

With uReader telematics platforms can implement in its AVL and FMS the new strategies in fuel economy and driving habits.

What is the FMS interface?

FMS Interface acts as a firewall limiting the data that can be obtained through the CANbus. It is the only connection point allowed by manufacturers to make the connection without losing the vehicle's warranty. Most vehicles do not have the FMS Interface enabled, so you can not get CANbus data without altering the warranty.

The uReader system does not require electrical connection to CANbus. Using a capacitive coupling system is possible to get all the bus information without altering the manufacturer's warranty.

uReader system:

  • replaces the FMS interface.
  • is smart and automatically detects the polarity and the speed of the bus.
  • transforms the signals from the vehicle to FMS standard.
  • filters unnecessary data making available only the relevant ones.
  • is compatible with most of trucks and buses manufacturers in the market.

The vehicle handles all communications (EDC, Retarder, Cruise, EBS, ABS, Injection, Fuel level, etc.) via internal CANbus. With uReader vehicle data can be read by any device with serial port, so you can have access to all information. uReader is compatible with other vehicle devices and can be combined with GPRS communications and GPS navigation..

Wheel Based Speed: Speed of the vehicle as calculated from wheel or tailshaft speed.

Clutch Switch: Switch signal which indicates that the clutch pedal is being pressed. It is necessary for a safe drivetrain behaviour that the clutch switch is set before the clutch is opened (cruise control function).

Brake Switch: Switch signal which indicates that the driver operated brake foot pedal is being pressed. This brake foot pedal is controlling the vehicles' service brake (total vehicle braking application, not park brakes). It is necessary for safe drivetrain behaviour that the switch activates before the physical braking components are activated (i.e. Disengage the cruise control function prior to the activation of friction brakes).

Cruise Control Active: Cruise control is switched on. It is not ensured that the engine is controlled by cruise control, as in the case of a large driver's demand the engine is controlled by the driver while cruise control is active (maximum selection of cruise control and driver's demand). The cruise control is set to 0 if a switch off condition occurs.

PTO state: This parameter is used to indicate the current state or mode of operation by the power takeoff (PTO) device. It needs to be ensured that each achieved state information be set up to be conveyed in at least one datalink message before a transition to another state is allowed.
Off/Disabled 00000b — Used to indicate that the PTO enable switch is in the off position.
Set 00101b — Used to indicate that the PTO device is establishing current speed as the operating speed (captured value).

The cruise control conditions might vary on different brands.
Wheel based speed might vary from tacho speed.
The PTO state might be different over the brands (not comparable) due to different internal topology.
Either SPN 3948 (PTO DE) or SPN 976 (CCVS) is sent. PTO DE message is preferred.

Accelerator Pedal Position: The ratio of actual position of the analogue engine speed/torque request input device (such as an accelerator pedal or throttle lever) to the maximum position of the input device. This parameter is intended for the primary accelerator control in an application. If an application has only one accelerator control, use SPN 91. For on-highway vehicles, this will typically be the operator's accelerator pedal. Although it is used as an input to determine powertrain demand, it also provides anticipatory information to transmission and ASR algorithms about driver actions.

Engine Percent Load At Current Speed: The ratio of actual engine percent torque (indicated) to maximum indicated torque available at the current engine speed, clipped to zero torque during engine braking.

Mandatory in all factory fitted FMS gateways.

Axle / Tire Location: To identify to which of several similar devices (such as tires or fuel tanks) the information applies.
The low order 4 bits represent a position number, counting left to right when facing in the direction of normal vehicle travel (forward).
The high order 4 bits represent a position number, counting front to back on the vehicle.
The value 0xFF indicates not available.
It is recommended that output devices add 1 to the position number (range 1 to 15, not 0 to 14) for use by drivers and service technicians.
Examples: Tire pressure for location 0x00 would be left front tire.Tire pressure for location 0x23 would be right outside rear rear on a 3-axle tractor with dual axle per side (3rd axle, 4th tire)

Axel weight: Total mass imposed by the tires on the road surface at the specified axle.

The repetition rate for this PGN is 1000ms and contains information about one axle.
If there are more axles available the information will be updated with each repetition (e.g. information about 3 axles will have a repetition of 3000 ms for each axle).
Please refer to the OEM documentation for more detailed information.

Information which specifies the capabilities of the Fleet Management System (FMS) - standard interface device.
This PGN typically is sourced from the network interconnect FMS - standard interface device.

Requests supported: Status signal which indicates if the FMS Vehicle Interface (FMS Gateway) will respond to requests from the FMS device for the PGNs listed in the FMS InterfaceSpecification.This mode is to support FMS gateway devices that only operate in a 'Request' mode.The FMS PGNs may also be broadcast periodically in this mode.The FMS Gateway will NOT support the requests for information not included in the FMS Interface Specification onto the vehicle network.

Diagnostics supported: Status signal which indicates if the FMS Vehicle Interface (FMS Gateway) supports the handling of diagnostic messages from the vehicle network onto the FMS network.
The FMS gateway does NOT support the re-broadcast of diagnostics messages present on the vehicle network. If this 'FMS-standard Diagnostics Supported' feature is supported by the FMS Gateway, the FMS Gateway will support the requests for diagnostics information (from the FMS device) onto the vehicle network and pass the responses onto the FMS network.
Note: This feature of the FMS Gateway is independent of the 'FMS-standard Requests Supported'. The FMS Gateway may support diagnostics without supporting the 'FMS-standard Requests Supported' function, or visa-versa.

FMS-standard SW-version supported: Information that identifies which issue level of the FMS-standard document the software included in the FMS gateway supports.
Four bytes, representing ab.cd type revision level identification.
Version number in the format ab.cd where byte2 and 3 represent the version number for trucks “ab” (ASCII)
Byte 3 and 4 represent the version for buses and coaches “cd”(ASCII) “00” represents “not supported”
For example, FMS-standard version 02.06 means the fms gateway supports version 02 of truck fms-standard and version 06 of bus fms-standard.
