VEHICLE AND METHOD FOR OPERATING SAME
A vehicle includes a drive motor with electrically upstream electric converter, a drive controller generating converter control signals actuating the converter for driving and normal braking operation, and an immobilizer electrically connected between the converter and the drive controller preventing converter control signals which would produce a driving operation of the drive motor from being forwarded to the converter when the vehicle is stopped, in particular at a stop. An alternate regulating device and a monitoring device allow activation of a special braking mode in the presence of an emergency braking command and in the event of which the drive controller is deactivated or at least signal flows of converter control signals of the drive controller to the immobilizer are interrupted, the immobilizer is activated, and converter control signals producing braking operation of the drive motor are transmitted to the converter through the immobilizer by the alternate regulating device.

Weight profile determination system
A weight profile determination system includes a sensor and a controller. The sensor is disposed along a route and configured to generate a plurality of force measurements of a vehicle system moving on the route relative to the sensor. The force measurements are obtained at different times and correspond to different locations along a length of the vehicle system. The controller is configured to determine a weight profile for the vehicle system based on the force measurements generated by the sensor. The weight profile represents a distribution of weight along the length of the vehicle system. The controller is configured to communicate the weight profile to one or more of the vehicle system or an offboard device for controlling movement of the vehicle system based on the weight profile.
METHOD FOR OPERATING A HYDRAULIC BRAKING SYSTEM, CONTROL UNIT AND BRAKING SYSTEM
The disclosure relates to a method for operating a hydraulic braking system for a motor vehicle with an electrified drive train. The braking system comprises a brake booster. First, a braking request is registered and it is determined that the braking request is to be met by pure recuperative braking. In addition, an input member of the brake booster is shifted in the direction of a pressure generation unit so that it assumes an actuation position corresponding to the braking request. From here, the input member is then shifted back from the actuation position in a direction away from the pressure generation unit for hydraulic pressure relief. A control unit designed to carry out such a method is also disclosed. A braking system comprising such a control unit is also presented.
