  • Patent number: 11491880
    Abstract: A vehicle control system determines an upper non-zero limit on deceleration of a vehicle to prevent rollback of the vehicle down a grade being traveled up on by the vehicle. The upper non-zero limit on deceleration is determined by the controller based on a payload carried by the vehicle, a speed of the vehicle, and a grade of a route being traveled upon by the vehicle. The controller is configured to monitor the deceleration of the vehicle, and to automatically prevent the deceleration of the vehicle from exceeding the upper non-zero limit by controlling one or more of a brake or a motor of the vehicle. The controller also is configured to one or more of actuate the brake or supply current to the motor of the vehicle to prevent rollback of the vehicle while the vehicle is moving up the grade at a non-zero speed.

  • Patent number: 10173532
    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.

  • Patent number: 10029664
    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.
