Abstract: The invention relates to a control system (1) for a vehicle provided with an electronically controlled drive train (2) which comprises a steering system (6), a braking system (7) and a transmission unit (4). An operating unit (10) generates a motion vector (BV) based on a driver's wish (FW), from which control signals (SS) are generated by a control unit (12) for controlling the drive train (2). In order to simplify maneuvering, more particularly reversing, a trajectory calculator (13) is provided, said trajectory calculator calculating the trajectory of movement for the situation and position of the vehicle (3) on the basis of actual values that are detected by a status and position determining device (14) and on the basis of set values that can be inputted by means of a target input device (15).

Abstract: In a control system for a vehicle equipped with an electronically actuable drive train, an operator control device generates a movement vector (from a driver request, and a control device generates control signals for actuating the drive train. A path computer calculates a movement path based on actual position/orientation values, and based on setpoint orientation and position values input via a destination-inputting device. The movement path includes a sequence of movement vectors which move the vehicle from its current actual orientation/position into the setpoint orientation and position when the drive train processes the movement vectors of the movement path. For this purpose, the path computer is coupled to the control device, in addition to the operator control device, via a common drive train interface in order to transmit the movement vectors.

Abstract: A surface active compound comprises at least one lipophilic group and at least one hydrophilic oxyethylated group linked together through acetal linkages so that, on acidification of an aqueous medium containing such a surface active compound, rupture of such acetal linkages permits separation of said lipophilic group, possibly with lipid material associated therewith, from the aqueous medium in which the oxyethylated groups remain so in turn permitting recovery of such lipophilic groups and any such lipid material, and effective elimination of active surface active compound from the aqueous phase.
