Situation 4: “M3-2T Control Mode “Spd/Torq”” = 3 (Torque control mode with speed mode at the end of
braking and at the end of footbrake operation) and “M3-4T Hill hold ”Off/HH/S”” = 0 (No Hill Hold)
In this case the controller acts to control the torque in normal drive and to control the speed at the end of braking and in
footbrake operation. 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 in case of neutral braking is the same of situation 3.
The sequence of operation of the “end of braking” function in case of footbrake operation is represented in the following
figure.
End of braking in FOOT BRAKING in Torque control Mode with Speed Mode at the end of braking and at the end footbrake
operation, no hill hold
The following list describes the “end of braking” steps:
1. the speed decreases according 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””);
2. when speed is below setting “M1-15T Speed threshold to enter end of braking mode ”SpdThEbM””, the
controller starts to control speed. The ramp time to zero is derived according to the brake pot position between
“M1-16T Speed threshold Ramp time to zero speed ”SpdRmpTm”” and “M1-17T Foot Brake Speed threshold
Ramp time to zero speed “SpdRTmFB”.
3. when speed is below “M1-18T Zero Speed Threshold to enter hill hold or neutral brake end ”ZSpdTh””, the
controller continues to control speed, slowing linearly down to zero according to “M1-16TSpeed threshold Ramp
time to zero speed ”SpdRmpTm””.
4. when the vehicle stops, it is held still until “M1-9T Neutral brake-End delay “NBrkEnd”” time is elapsed and the
footbrake has not been released. The vehicle is kept still by means of speed control algorithm;
5. 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.
