M1.13-1 Drive torque allowed during braking ”DTrq@Brk”
This set is active only in speed mode.
• If set to 0 (no drive torque allowed during neutral and foot braking), the controller won’t apply drive
torque during deceleration speed ramp in neutral braking or foot braking. In vehicles equipped with
mechanical brake, set this to zero to avoid speed control to fight against mechanical brake during foot
braking. This is also useful for customers that like the vehicle being stopped by slope effect when driving
uphill and release the accelerator pedal.
• If set to 1 (drive torque allowed during braking), the controller can apply drive torque if necessary to
follow the deceleration speed ramps (neutral, inversion and foot brake). This option is suggested for
vehicle without mechanical brakes and with electromagnetic brake. Be aware that, when this option is on,
when the Simga2NController is operating a neutral brake while driving uphill, the Simga2N Controller will
compensate the braking effect of the slope to keep following the brake ramp time.
• If set to 2 (no drive torque allowed during neutral, foot and direction braking), the behaviour is the same
as described for option 0, with the only difference that drive torque will not be applied also when direction
braking.
M1.13-2 Drive torque during braking release time “DrvTRmDw”
This setting is only active in speed mode and when parameter “M1.13-1 Drive torque allowed during braking
”DTrq@Brk”” is set to 0.
It is used to avoid that drive torque is cut too quickly and an uncomfortable drive feeling is experienced when
accelerator is fully released. It therefore sets a time in which driving torque is cut, instead of cutting it
completely and immediately, when the accelerator is fully released. Increasing the value will also help to reduce
the roll back when fully releasing the pedal while climbing on a slope. Too long value will cause a bad drive
feeling. The suggested value for this setting is between 0.7s and 1.0 s.
M1.13-3 Drive torque during braking rise time “DrvTRmUp”
This setting is only active in speed mode and when when parameter “M1.13-1 Drive torque allowed during
braking ”DTrq@Brk”” is set to 0.
This correspond to the time taken to build up the torque when hill hold becomes active at the very end of
braking. Increasing the value will smooth the activation of holding torque, but if set too long it will cause more
roll back. The suggested value is between 0.5s and 2s.
