CONTROL SYSTEM FOR CONTROLLING AN ARM OF A CONSTRUCTION VEHICLE

Control system for controlling a controllable arm (12) of a vehicle (10), comprising: an aggressiveness switch (29) operable to manually select a jerk; a transmission state selecting mean (42) operable to select a transmission state; sensor means for acquiring sensor signals indicative of working conditions of the vehicle (10); and a control unit (30). The control unit (30) is configured to: receive, at a current time instant (t*) and during a preceding period of time (ΔT), the transmission state, the manually selected jerk and the sensor signals; if the transmission state at the current time instant (t*) is indicative of a forward state, generate a jerk command indicative of the manually selected jerk, otherwise compare the transmission state and the sensor signals acquired during the preceding period of time (ΔT), with reference signals; based on the comparison, generate at the current time instant (t*) the jerk command indicative of either the manually selected jerk or of a predetermined jerk. The jerk command controls a jerk of the controllable arm (12). The predetermined jerk is either a lowest manually selectable jerk, or is lower than the manually selected jerk.
