TL0103008 - Inertial Measurement Unit (White)
Description
White IMU is allowing to have two IMUs in the car. White and Black IMU work with different addresses so then you can data from different sources. This will allow installing IMU e.g. on both front and rear axle to get more details about under and oversteering.
Technically White IMU has the same specification so it measures the same things with same accuracy.
Package contents
1 x Inertial measurement unit (IMU)
1 x 20cm 4-pin cable
1 x 5cm 4-pin cable
1 x BUS signal splitter
Installation
Try place the IMU as close as possible to CoG of the car if only IMU is installed. If car has two IMUs (black and white), then recommendation is to install IMUs on top of driven axles.
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.
Configuration
As the IMU has two sensors in one, then both sensors need to be configured separately.
In normal situation Basic settings should be enough to configure the channel. Use Advanced parameters only if you know what you are doing.
Accelerometer paremeters
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 White | 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 |
Gyro parameters
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 | Gyro | 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 Gyro White | Change the sensor type. |
Decimals | Advanced | Integer | 1 | 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 | Angular velocity (deg/s) | 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 |
