Gear Management

Gear Management

The first step to proper gear management/detection is a properly scaled and validated speed signal.

Gear Management in Emtron can be detected in various ways.

Fundamentally, gear control and detection are a part of the ECU functions.

Several channels are linked to the gear functions that can be viewed, logged, and used as active channels :

Gear Position (RPM/Speed) Setup

Gear Detection Ratio Calculation stops when the speed fall below this value.

0 = OFF

Typical: 2-5.

Default gear for Gear Detection Ratio Calculation.

Typical: 10ms

Typical: 10%

Fault Time for Gear Detection Ratio Calculation.

Typical: 1000ms

Gear Ratio Detection Calculation temporary stops when the Clutch Switch is ON i.e. during a gear change.

Clutch Switch Input Channel MUST be configured

Define the multiplier here to get speed for the ratio calculation to work. IE:

100kph *34 in 5th gear = 3400rpm.

Speed channel must be configured and scaled

RPM/Speed ratio is also actively calculated in Runtimes

Gear Ratio (Input/Outputshaft Speed) = Inputshaft Speed Source/ Outputshaft Speed Source

Gear Detection Ratio Calculation stops when the Outputshaft speed fall below this value.

0 = OFF

Typical: 2-5.

Default gear for Gear Detection Ratio Calculation.

Typical: 6ms

Typical: 7%

Typical: 10ms

Define the transmission ratios the ECU should expect for calculating gears via Input/Outputshaft speed correlation

Actual Gear Ratio (Input/Outputshaft) can be validated actively calculated in Runtimes
