Situation 2: “M3-2T Control Mode “Spd/Torq”” = 1 (Torque control mode) and “M3-4T Hill hold
”Off/HH/S””=0 (No Hill Hold)
In this case the controller acts to control the torque and no hill hold is selected, thus the parameters “M1-19T Hill hold
time ”HHTime””, “M1-20T Restraint hill hold speed ”HHspeed”” and “M1-21T Restraint hill hold torque threshold
”HHTrqTH”” won’t be active.
The sequence of operation of the “end of braking” function is represented in the following figure.
End of braking in Torque control Mode and no hill hold
The following list describes the “end of braking” steps:
1. the speed decreases according to “M1-7T Neutral Brake torque “NBrake”” (if neutral braking is happening) or to
“M1-13T Foot brake torque “FBrake”” and the “Brake pot %” value (refer to “M1-54T Brake pot minimum
“BrkMin”” and M1-55T Brake pot maximum “BrkMax””) (if foot brake is operated);
2. when speed is below setting “M1-15T Speed threshold to enter end of braking mode ”SpdThEbM””, the
controller reduces brake torque in a smooth way (proportionally to speed) to assure a smooth stop operation;
3. when speed is below “M1-18T Zero Speed Threshold to enter hill hold or neutral brake end ”ZSpdTh””, the
vehicle is let coast with the controller pulsing until “M1-9T Neutral brake-End delay “NBrkEnd”” time is elapsed;
4. the controller stops pulsing and the vehicle is let coast or roll on slope (if any) unless mechanical brake or
electromechanical brake is applied.
During the end of braking operation, If pedal brake is removed and a direction selected with accelerator pedal demand
(add foot switch in case of ride vehicle) the vehicle will start to move in the selected direction.
