4.14.1. Overview

The Gear Selector Switch Pack Driver component can process analog voltage as well as digital inputs from the gear selector switch pack to determine the selected gear position. It provides the gear selection status and button statuses as outputs.

4.14.2. Functions

Title	Description
Gear Selection Control	Determines the desired gear based on driver and vehicle requests (either analog or digital), and controls the gear selection actuator to engage the selected gear.
Gear Selector Position Monitoring	Monitors the position of the gear selector (PRND) and provides the selected gear as an input to the gear selection control logic.

4.14.5. Configuration Guide

GearSelrSwtPkDrvr component processes gear buttons/selector voltage inputs and shall be configured for a specific vehicle electrical characteristics.

4.14.5.1. Step 1 - Input type selection

Set GsswtpkAnInp to true to select the analogue input type for Gear Switch pack (See Step 1.1 and 1.2 to configure the inputs characteristics).
Set it to false to select the digital instead.

4.14.5.2. Step 1.1 - Configure RND Buttons/Selector (AIN)

Set up the Reverse, Neutral, and Drive (RND) button voltage thresholds and timing parameters.

• Set RND Button Nominal Voltages
  Configure GsswtpkRvsNeutDrvVoltTbl to define voltage levels for detecting Reverse, Neutral, and Drive button presses.
  Adjust GsswtpkRvsNeutDrvVoltTolr to specify allowable variations in button detection.
  Configure GsswtpkRvsNeutDrvVoltRef to establish the expected nominal voltage values for each button.
  

• Configure off-nominal Voltage Fault Detection Define GsswtpkSelTiOut to set the time duration for button selection confirmation.
  Adjust GsswtpkErrTiOut to specify the timeout period before triggering an error due to button inactivity or misdetection.
  

4.14.5.3. Step 1.2 - Configure Park Button/Selector (AIN)

Configure the Park button functionality based on the system characteristics (VCU or Braking ECU).

• Enable or Disable Park Button Processing
  Set GsswtpkParkBtnEna to true to allow Park button handling within the Gear Selector Switch Pack Driver.
  

• Set Park Button Nominal Voltages

  Configure GsswtpkParkVoltTbl to define expected voltage levels for Park button operation.
  Adjust GsswtpkParkVoltTolr to allow for acceptable deviations in Park button voltage readings.
  Configure GsswtpkParkVoltRef to establish the nominal reference voltage for Park button detection.
