1. A process for controlling a start-stop operation of a vehicle, having a hybrid drive with an internal-combustion engine and an electric motor, a service brake with an ABS and an electric parking brake, the process comprising the acts of: determining, monitoring and analyzing performance parameters of the vehicle, of the internal-combustion engine, of the electric motor, of the service brake and of the electric parking brake, the performance parameters including vehicle speed, rotational wheel speed, rotational speeds of the internal-combustion engine and of the electric motor, operations and conditions of a service brake pedal, of a parking brake pedal and of an accelerator pedal;automatically releasing the electric parking brake in the case of a starting prompt because of determined performance parameters;driving the vehicle by the electric motor for the start;starting the internal-combustion engine by the electric motor if the internal-combustion engine is switched off;driving the vehicle by the electric motor and the internal-combustion engine;activating a generator operation of the electric motor in the case of a braking prompt because of determined performance parameters;activating the service brake; andautomatically locking the electric parking brake when the vehicle is stopped after a previously definable deceleration time;when a circuit defect of the service brake is determined in the process act of determining, monitoring and analyzing performance parameters and, when the vehicle is driving, a braking prompt takes place by the service brake pedal and/or the parking brake lever, the process, for an emergency running function, further comprises the acts of: activating a generator operation of the electric motor;activating the electric parking brake; andautomatically locking the electric parking brake when the vehicle is stopped after a previously definable deceleration time. 2. The process according to claim 1, wherein the process acts of automatically releasing the electric parking brake and driving the vehicle by the electric motor are carried out simultaneously. 3. The process according to claim 1, wherein the process act of starting the internal-combustion engine is carried out after expiration of a previously definable time period after the process act of driving the vehicle by the electric motor. 4. The process according to claim 1, wherein the process acts of activating the generator operation of the electric motor and activating the service brake are carried out simultaneously. 5. The process according to claim 1, wherein the process act of activating the service brake is carried out after expiration of a previously definable time period after the activating of the generator operation of the electric motor. 6. The process according to claim 1, wherein, in an event of a braking prompt, a brake system of at least one trailer of the vehicle is activated in a synchronous manner. 7. A process for controlling a start-stop operation of a vehicle, having a hybrid drive with an internal-combustion engine and an electric motor, a service brake with an ABS and an electric parking brake, the process comprising the acts of: determining, monitoring and analyzing performance parameters of the vehicle, of the internal-combustion engine, of the electric motor, of the service brake and of the electric parking brake, the performance parameters including vehicle speed, rotational wheel speed, rotational speeds of the internal-combustion engine and of the electric motor, operations and conditions of a service brake pedal, of a parking brake pedal and of an accelerator pedal;automatically releasing the electric parking brake in the case of a starting prompt because of determined performance parameters;driving the vehicle by the electric motor for the start;starting the internal-combustion engine by the electric motor if the internal-combustion engine is switched off;driving the vehicle by the electric motor and the internal-combustion engine;activating a generator operation of the electric motor in the case of a braking prompt because of determined performance parameters;activating the service brake; andautomatically locking the electric parking brake when the vehicle is stopped after a previously definable deceleration time;when in the process act of determining, monitoring and analyzing of performance parameters, a defective service brake pedal is determined and, when the vehicle is driving, a braking prompt takes place by the service brake pedal and/or the parking brake lever, the process, for an emergency running function, further comprises the acts of: activating operable electric modules of a control unit ABS of the service brake;activating a generator operation of the electric motor;activating the electric parking brake; andautomatically locking of the electric parking brake when the vehicle is stopped after a previously definable deceleration time. 8. The process according to claim 7, wherein, during the process act of activating a generator operation of the electric motor, the generator operation is adjusted in steps. 9. The process according to claim 7, wherein, during the process act of activating the electric parking brake, the parking brake is adjusted in steps in previously definable ranges. 10. The process according to claim 8, wherein, during the process act of activating the electric parking brake, the parking brake is adjusted in steps in previously definable ranges. 11. The process according to claim 9, wherein, by use of the performance parameters determined in the process act of determining, monitoring and analyzing, a corresponding assist torque of the electric motor is calculated for assisting or implementing the stepped ranges of the parking brake. 12. The process according to claim 7, wherein, in an event of a braking prompt, a brake system of at least one trailer of the vehicle is activated in a synchronous manner.
