    Abstract: A control system for a vehicle includes an electric drive system associated with a first set of wheels (e.g., rear wheels) of a vehicle and a drive system control unit configured to control the electric drive system to selectively provide electric motive power to the first set of wheels to propel the vehicle and electric retarding to slow the vehicle. The system further includes a friction brake system having a first friction brake unit associated with the first set of wheels and a second friction brake unit associated with a second set of wheels (e.g., front wheels) of the vehicle. The drive system control unit is further configured, in at least one mode of operation, to independently control the first and second friction brake units to concurrently apply different levels of friction braking to the first and second sets of wheels, to reduce wear unevenness.

    Abstract: A route inspection system includes one or more processors configured to identify a reference location in sensor data provided by one or more sensors onboard a vehicle system. The reference location is identified along a route being traveled by the vehicle system. The one or more processors also are configured to identify a location of interest in subsequent sensor data provided by the one or more sensors. The location of interest identified along the route being traveled by the vehicle system. The one or more processors also are configured to determine a degree of curvature in the route based on a difference between the reference location and the location of interest.

    Abstract: A system includes a route examining system on a non-propulsion-generating vehicle at a trailing end of a leading vehicle system. The route examining system examines a route on which the leading vehicle system is moving to determine whether the route is damaged. The system also includes an off-board failsafe controller that communicates with the route examining system. The off-board failsafe controller sends a warning signal to the trailing vehicle system responsive to receiving a notification signal from the route examining system indicating detection of damage to the route. The off-board failsafe controller also sends the warning signal to the trailing vehicle system responsive to losing communication with the route examining system. The warning signal directs the trailing vehicle system to automatically change movement of the trailing vehicle system responsive to the detection of damage to the route and/or the off-board failsafe controller losing communication with the route examining system.

    Abstract: A braking system for a vehicle includes an electric drive system associated with a first set of wheels. The electric drive system is configured to selectively provide electric motive power to the first set of wheels of the vehicle to propel the vehicle and electric retarding to slow the vehicle. The system further includes a friction brake system associated with a second set of wheels of the vehicle, and a controller for selectively actuating the electric drive system to operate in an electric retarding mode and for selectively actuating the friction brake system. The controller is configured to transfer retarding force from the first set of wheels to the second set of wheels, and/or to determine wheel speed signal accuracies, in either case to mitigate vehicle/wheel sliding or slipping.
