- the brake pressure lines of the ICE4 and the pre-tension locomotive are connected to each other. If the driver of the lead locomotive generates a brake command, this leads to a reduction in pressure in the coupled brake lines and activation of the ICE4 brakes by means of the pneumatically controlled brake control modules.
- the invention is based on the object of improving a vehicle of the type described at the outset, also with regard to the pretensioning operation described.
- a control signal transmitter is connected to a pressure line on the rail vehicle via a pressure detection device and the control signal transmitter can generate the electrical brake control signal for electrically actuating the electrically controllable brake control module as a function of the respective pressure in the pressure line on the rail vehicle.

- the latter aspect has the important advantage that the braking behavior of the rail vehicle remains unchanged even in the event of repeated braking and "fatigue" occurring as a result of a gradual pressure drop in the pneumatically controllable brake control modules, because the non-fatiguing electrically controllable brake control modules maintain or increase the desired braking behavior .can compensate for the gradual, temporary failure of the pneumatically controllable brake control modules.

- the control signal transmitter preferably has an interface for entering an input signal, with which the control signal transmitter can be activated or deactivated in whole or in part.
- control signal transmitter is activated in the preload operation and is otherwise deactivated in whole or in part.
- the pressure detection device is preferably arranged in the area of the brake pressure interface coupled to the lead locomotive in order to enable the electric brake control signal to be generated with as little delay as possible in the event of a pressure drop in the brake pressure lines caused by the locomotive driver of the lead locomotive.
- the vehicle has two or more brakes that are equipped with electrically controllable brake control modules.
- a vehicle control device is preferably present, which is connected to the electrically controllable brake control module(s) of the brakes of the vehicle and can control them.

- the control signal transmitter is preferably integrated into the vehicle control unit as a software component.
- the vehicle control unit preferably includes a braking force distribution device and a pressure/braking force conversion device.
- the pressure-braking force conversion device preferably forms a prestressing operational braking force specification as a function of the respective pressure in the rail vehicle's own pressure line.
- the brake force distribution device works in the bias mode together with the pressure-brake-force conversion device, preferably as said control signal generator and generates the electrical brake control signal depending on the braking force specification of the pressure-brake-force conversion device before tensioning operation.
- the electric brake control signal is preferably generated as a function of a normal operation-related braking force specification, which depends on an operating position of a brake operating element of the vehicle.
- the conversion of the normal jossffle lar braking force specification can be carried out in the brake control signal by an additional braking force distribution device; alternatively and particularly advantageously, in the normal the conversion of the braking force specification during normal operation into the brake control signal can also be carried out by the braking force distribution device that also forms the control signal generator.
- the control signal generator is not completely deactivated in normal operation, but only in parts, for example with regard to the influence of the pressure-brake force conversion device on the braking force specification, the braking force distribution device remains active.

- the software When executed by the computing device, the software preferably defines the mode of operation of the vehicle control unit.
- the braking force distribution device and the pressure-braking force conversion device are preferably implemented as software program modules in the software.
- Pressure measuring devices are preferably arranged in the area of both ends of the rail vehicle, especially in the case of a multi-unit vehicle, in the front and rear car, in order to always enable a pressure measurement close to the locomotive if a lead locomotive is coupled to the front or rear end.
- the invention also relates to a method for operating a vehicle, in particular a rail vehicle, which is equipped with at least one brake which can be actuated by an electrically controllable brake control module which can control the brake pneumatically as a function of an electrical brake control signal present on the input side.
- a rail vehicle pressure line is detected and the electrical brake control signal for controlling the electrically controllable brake control module is generated as a function of the respective pressure in the rail vehicle pressure line.
- the brake can also be actuated pneumatically via a pneumatically controllable brake control module as a function of the respective pressure in the pressure line, if there is a connection between the rail vehicle's own pressure line and an external pressure line of a prestressing locomotive via a brake pressure interface and, in prestressing operation, a transmission of a Brake pressure is reduced in the external pressure line of the lead locomotive to the rail vehicle's own pressure line, and in the event of a possible pressure reduction in the interconnected pressure lines, the brake is actuated both electrically via the electrically controllable brake control module and pneumatically via the pneumatically controllable brake control module.
