TL0103001 - Inertial Measurement Unit¶

Description¶

IMU has two sensors included. First one is Accelerometer 1 and second sensor is Gyro 1.

Try place the IMU as close as possible to CoG of the car.
Make sure the IMU is aligned straight related to chassis.
Arrow in the IMU should point forward and arrow is the top side.
IMU can be installed in reverse (arrow pointing backwards) in case it makes it easier to do the wiring. In case it's installed in reverse way, then reverse settings needs to be set 1 in the configuration for both Accelerometer and Gyro
Connect IMU to main unit with 4-pin cable. Always connect to port BUS.

Image 2: Example installation with sensor reversed.

As the IMU has two sensors in one, then both sensors need to be configured separately.

Tip

In normal situation Basic settings should be enough to configure the channel. Use Advanced parameters only if you know what you are doing.

Parameter	Visibility	Type	Default value	Description
Enable	Basic	Boolean	yes	Parameter is used to enable the sensor for logging. Sensor is enabled if value is yes.
Inverted	Basic	Boolean	no	This is used to invert the x-axis and y-axis values in case sensor is installed arrow point rear of the car.
Name	Advanced	String	Accelerometer	Channel name to be used in the exported data file. Data file will have own channel for all three dimensions and system will add the axis identifier after the channel name
Type	Advanced	Option	BMI088 Acc High	Change the sensor type.
Decimals	Advanced	Integer	3	Number of decimals in the logged data
Sampling time	Advanced	Option	10ms	Sampling time for the channel
Filter	Advanced	Integer	1	Gives the possibility to filter accelerometer values. 1 = no filter, 9 = max filter
Unit	Advanced	Option	G Force (G)	Select the unit for exported data file. No effect on the calculation.
Size in bytes	Advanced	Option	16bit	Defines data sample size in raw data. Options are 16bit value and 32bit value
