  • 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: 11891098
    Abstract: It is imperative that the integrity of a train and its railcars be maintained. A defective part or parts on a train may cause the derailment of the train and its railcars. A derailment often causes serious personal and property damage. The use of artificial intelligence that has been applied to this system will detect possible flaws or defects in the railroad car. A portal through which the train will pass houses cameras and a means of illumination to take high resolution images of the train through the portal. This information is then stored on a software platform. It has a feature which can include a human in the loop process that verifies the accuracy of the information. The solution also transmits detected defect images and information to a remote location for analysis.

  • 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: 11708101
    Abstract: A vehicle orientation determination system includes one or more processors configured to determine a first distance between a reference device disposed on a first vehicle and a front device disposed on a second vehicle. The first and second vehicles are both disposed on a route. The one or more processors are further configured to determine a second distance between the reference device disposed on the first vehicle and a rear device disposed on the second vehicle. The front device is located more proximate to a front end of the second vehicle than a proximity of the rear device to the front end. The one or more processors are configured to determine that the second vehicle has a common orientation as the first vehicle relative to the route based on the first distance being less than the second distance.

  • Patent number: 11691657
    Abstract: A vehicle control system and method wirelessly communicate from at least one wireless transmitter positioned proximate a route crossing to a wireless receiver of a vehicle via a wireless wayside transceiver. The system and method communicate an indication of whether the route crossing is clear for passage of the vehicle through the route crossing. The system and method receive the indication by the wireless transmitter and using the vehicle receiver. A vehicle controller or an operator of the vehicle can determine whether it is safe for the vehicle to travel through the route crossing based on the indication received by the vehicle receiver from the portable transmitter. The vehicle can then be operated based on the determination.

  • Patent number: 11679750
    Abstract: A system for monitoring usage of rail car brake equipment and determining whether the actual lifespan of the brake equipment is shorter than an expected lifespan had the brake equipment been used under normal or constant parameters. The system includes a sensor for collecting and outputting data indicating how the brake equipment has been actually used. A controller is programmed to receive the data regarding how the brake system component has been used and to calculate whether the brake system component has an estimated lifespan that is shorter than the expected lifespan. The sensor may comprise an ambient temperature sensor, a flow sensor that determines the air used by the braking system that includes the brake system component, and/or a pressure sensor that can determines how frequently and in what manner the brake system has been used.
