Launch Control (Nm) Setup

Launch Control (Nm) 

Entry Range 

Controls when the Launch Torque Limit function will turn ON.

The Launch Torque Limit and PID control will switch ON when the RPM enters set range of the Launch RPM Target. 

This is a negative engine speed value that sets the range below the Launch RPM Target

Once ON it will latch and remain ON until the system exits to standby mode

Exit of the Launch control is user defined in Launch Disarming

Example:

Launch RPM Target = 4000

Entry Range  = -200 

Rpm < 3800 Launch Control Torque Limit is OFF

Rpm >= 3800 Launch Control Torque Limit is ON

Torque Target Margin

This setting is used to increase/decrease the Engine Torque Target once the engine is within the Entry Range of the Launch RPM Target.

The margin is added to the Launch Torque target on entry and decays to the Launch Torque Target at a linear rate as the engine approaches the Launch RPM Target.

Tuning Tip: 

Use 0Nm initially as a starting point.  This setting is used to control the entry behavior.  

** If the engine is struggling to reach Launch Target, Increase Margin

Example: 

Launch RPM Target = 3000 RPM

Entry Range = -200 RPM

Launch Torque Target = 10 Nm

Launch Torque Target Margin = 100Nm

RPM < (Launch RPM Target - Entry Range )  the Torque Limit is OFF

RPM > (Launch RPM Target - Entry Range) the Torque Limit is latched ON

Rpm < 2800. Torque Limit OFF

Rpm = 2800. Torque Target = 10Nm + 100Nm = 110Nm

Rpm = 2850. Torque Target = 10Nm + 75Nm = 85Nm

Rpm = 2900. Torque Target = 10Nm + 50Nm = 60Nm

Rpm = 2950. Torque Target = 10Nm + 25Nm = 35Nm

Rpm = 3000. Torque Target = 10Nm + 0Nm   = 10Nm

Launch Torque Transfer User Channel 

Allows the User to control when the Torque Target transitions from  “Static Torque Target” table to the  “Launch Moving Torque Target”

** This User MUST be set up or Launch Control will not enable

Example:

Trans Brake Switch Status could be used as a user channel input to trigger the transition from Launch Torque Target to Launch Moving Torque Target

Launch Static Mode Speed Lockout

When the speed input is greater than this value, the Launch System will lockout the “Static Torque Target" and maintain the “Moving Torque Target". This prevents the accidental return of the launch system back into Static Mode.

** NOTE: Make sure the “Launch Speed Reference Channel” is set correctly **

Typical Value = 10 kph

Launch Speed Reference Channel

Defines the speed channel used to Disarm/Arm the Launch Control System.

Launch Enable Switch Lockout 

When set to ON the Launch Switch can be used to activate the Launch Control System.

0: OFF

1: ON

ET Lo Lockout 

This is an under-temperature lockout. The Launch Control system will be ready for arming when the Engine Temperature is greater than this value.

For the Launch System to be ready for arming the following must be true:

Throttle/Pedal > Launch TP/PP Lockout setting AND

Engine Temperature > ET Lo Lockout setting AND

Engine Temperature < ET Hi Lockout setting AND

User Lockout = ON (if enabled)

ET Hi Lockout 

This is an over-temperature lockout. The Launch Control system will be ready for arming when the Engine Temperature is less than this value.

For the Launch System to be ready for arming the following must be true:

Throttle/Pedal > Launch TP/PP Lockout setting AND

Engine Temperature > ET Lockout setting AND

User Lockout = ON (if enabled)

Launch User Lockout 

The Launch Control system will be ready for arming when the User Channel (if assigned) is ON.

For the Launch System to be ready for arming the following must be true:

Throttle/Pedal > Launch TP/PP Lockout setting AND

Engine Temperature > ET Lockout setting AND

User Lockout = ON (if enabled)
