Abstract: 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.

Abstract: A current collector for a non-rail-bound, electric traction vehicle has an articulated support linkage, which, on the contact wire side, supports rocker assemblies with contact strips and, on the vehicle side, has a base joint for articulation to the traction vehicle. A pneumatic reciprocating drive is coupled to the support linkage for raising the rocker assemblies from a lower parking position into an upper contact position when the reciprocating drive is pressurized and for lowering into the parking position under its own weight when depressurization occurs. An exhaust air line connects the reciprocating drive to the environment to lower the rocker assemblies. An air accumulator and a downstream throttle valve are connected between the reciprocating drive and an environment opening of the exhaust air line. The rocker assemblies can be quickly lowered and nevertheless brought into the parking position without damage in order to disengage the current collector.

Abstract: A vehicle, particularly a rail vehicle, includes at least one brake resistor assembly having electrical brake resistors which can receive electrical braking energy and convert the electrical braking energy into waste heat during braking operation of the vehicle. The brake resistors are divided into a first subgroup and a second subgroup, the first sub-group and the second sub-group are electrically connected in parallel, and an evaluating device monitors functional capability of the brake resistors on the basis of a measured variable indicating a differential current between a first subgroup current flowing through the first subgroup and a second subgroup current flowing through the second subgroup. A method for monitoring electrical braking resistors of a vehicle is also provided.
