Important notes
1. To use
IMU04
integration, a
VB3i-V3, V4 or V5
must be used. This is an IMU04 enabled VBOX 3i unit.
2. IMU04 cannot be used with IMU integration if it is connected to a VBOX via CAN (RLCAB120 / RLCAB005-CS).
This method of connection will only allow standard IMU channels to be logged. See
section for details.
3. The IMU04 standard channels can also be logged when the IMU04 is connected via KF port with cable
RLCAB119, without enabling IMU integration.
4. The IMU04 must be in a Racelogic CAN mode to be used for IMU Kalman Filter.
5.
NB ADAS -
If using IMU Integration with an ADAS mode, the GPS antenna and IMU should be co-located (
) or positioned so there is no relative X or Y offset between them. If there is a difference, manual contact
points should reference the IMU location, rather than the GPS antenna.
6.
NB ADAS -
When using IMU Integration, the user cannot use Set Points functionality to define contact points in
single or multi target ADAS modes.
Wheel Speed Inputs
Vehicle speed data can be combined with inertial IMU data to provide increased data accuracy in environments that
have poor satellite reception, such as areas with trees, buildings, bridges or tunnels. More information on this can be
found
In order to obtain the wheel speed information, the best solution is to use the sensors already fitted to the vehicle by
connecting to the vehicle’s CAN bus by using an RLCAB069L, RLCAB015L or RLACS182L cable. Before testing
commences, ensure that the VB3i unit is correctly connected to either the speed sensors or to the vehicle CAN bus.
Wheel speed input needs to be '
Enabled
' and configured, this can be done via the
or using the
. However, wheel speed CAN inputs can only be configured using VBOX Setup Software.
VBOX Setup Software
1. Ensure IMU04 is connected via RLCAB119, and the VBOX 3i is powered on.
2. Connect VBOX 3i to a computer either via Bluetooth, an RLCAB001 cable to the '
SER
' input and the computer's
serial port (usb-serial adapter may be required), or via an RLCAB066-2 cable to one of the computer's USB ports.
3. Open
VBOX Setup
and connect to VBOX 3i by selecting
COM Port
.
4. Select the '
IMU
' menu and then the '
Wheel speed input
' tab.
