  • Patent number: 11958515
    Abstract: A method for identifying properties of rail-guided vehicles uses an axle counter to detect vehicle measurement data as the vehicle crosses. The measurement data are analyzed in a computer and speed and distances between vehicle axles are ascertained. A property of the vehicle is ascertained in a computer based on the ascertained speed and distances between axles. A checking step ascertains a pattern of normal distances between axles in that a normal distance between axles calculated by considering a predefined normal speed is assigned to each ascertained distance between axles, and by considering their order, the normal distances between axles merge to form the pattern. The pattern is compared with reference patterns, and upon identified conformity of the pattern and reference pattern, a type linked to the reference pattern is assigned to the vehicle as a property. An apparatus and computer program determining properties of vehicles are also provided.

  • Patent number: 11904697
    Abstract: A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

  • Patent number: 11866075
    Abstract: The position of a rail vehicle that is parked on a track is monitored in a cold movement detection. A vehicle-side device of an automatic train safety system is deactivated when the vehicle is parked. Prior to the deactivation, a first positional value is determined by the automatic train safety system, and independently, a second positional value is determined by another localization system. With the vehicle-side device deactivated, the actual position of the vehicle is monitored by the other localization system. The additional positional values and/or a deviation of the actual position from a target position is transmitted to a track-side device of the train safety system. When the vehicle-side device is activated, the track-side device transmits the actual position of the vehicle to the vehicle-side device. If the vehicle has not moved, the automatic train guidance system can immediately assume the monitoring process starting from the first position.

  • Patent number: 11745707
    Abstract: A system and method for reducing the threat of derailment of a train during deceleration is provided. An individualized braking force for each rail car of a train, such individualized braking force being determined by the braking deceleration of the train's locomotive, may be calculated by the rail car's controller and is directly proportional to the mass of the rail car. The controller may utilize the various forces acting upon the individual rail car as measured by a plurality of sensing and measuring devices to dynamically adjust the braking force applied to the individual rail car's brakes. Such a system and method allows for the train to act as a single body mass when decelerating to eliminate rail car pile-up and reduce the threat of derailment.
