Vehicle control system
First Claim
1. A control system for a vehicle having an electronically actuable drive train which includes at least one steering system, a brake system and a drive assembly;
- an operator control device for generating a standardized movement vector in response to a driver request input therein;
a second control device, which is coupled to the drive train for generating control signals based on said standardized movement vector received from the operator control device, to actuate the drive train, which processes the control signals in order to implement the driver request; and
a drive-train interface via which the operator control device is coupled to the control device in order to transmit the standardized movement vector;
said control system further comprising;
a path computer;
an orientation- and position-determining device, which is coupled to the path computer, and which continuously determines actual values for orientation and position of the vehicle, and transmits the actual values to the path computer;
a destination-inputting device, into which setpoint values for the orientation and position of the vehicle can be input and which is coupled to transmit the setpoint values to the path computer;
whereinthe path computer calculates a movement for the vehicle path based on the actual values and the setpoint values, which movement path is composed of a sequence of standardized movement vectors that move the vehicle from its actual orientation and position into the setpoint orientation and position when the movement vectors of the movement path are processed;
the path computer is also coupled to the control device via the drive train interface in order to transmit the movement vectors.

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). The trajectory of movement consists of a sequence of motion vectors (BV), which move the vehicle from its actual status and actual position to the set status and set position when the drive train (2) executes the motion vectors (BV) of the trajectory of movement. For said purpose, the trajectory calculator (13) is coupled to the operating unit (10) and additionally to the control unit (12) by means of a common drive train interface (11) for transmitting the motion vectors (BV).
