Patent ID: 7276015

Claim:
An arrangement in an engine-driven goods vehicle comprising: an engine drivingly associated with paired sets of drive wheels ( 9 , 10 and 51 , 52 ); a differential ( 5 , 6 , 45 , 46 , 47 ) arranged between the paired drive wheels ( 9 , 10 and 51 , 52 ) of a set and including differential locks ( 7 , 8 , 48 , 49 , 50 ) for locking and braking respective differentials ( 5 , 6 , 45 , 46 , 47 ); and a control unit ( 3 ) configured to control the engine and the differential lock ( 7 , 8 , 48 , 49 , 50 ) and reduce positive and negative output torque of the engine ( 1 ) to a maximum allowable torque level, after having receiving an input signal indicating that at least one differential lock ( 7 , 8 , 48 , 49 , 50 ) is activated wherein said drive wheels comprise at least two paired sets of drive wheels ( 9 , 10 , 51 , 52 ), each set having a differential ( 5 , 6 , 45 , 46 , 47 ) and a differential lock ( 7 , 8 , 48 , 49 , 50 ) associated therewith, wherein the control unit ( 3 ) limits positive and negative output torques of the engine ( 1 ) to a maximum allowable level dependent upon which differential locks ( 7 , 8 , 48 , 49 , 50 ) are activated.
