  • Publication number: 20220099038
    Abstract: An apparatus includes a control circuit. The control circuit is structured to interpret condition data indicative of an external operating condition of a vehicle, determine an operating parameter of the vehicle based on an actuator response of an actuator of the vehicle, compare the operating parameter to an operating parameter threshold where the operating parameter threshold is based on the external operating condition, and remap an actuator response map of the actuator based on the comparison indicating that the operating parameter does not satisfy the operating parameter threshold. The operating parameter includes at least one of a fuel economy value, an emissions value, an acceleration value, a braking value, or a wear value.

  • Patent number: 10579953
    Abstract: Systems and methods of vehicle freight/load distribution are provided to assist in determining optimal freight distribution. Although it is standard practice to fill each vehicle to its maximum limit, due to the non-linear nature of engine fueling maps (that is, fueling maps vary non-linearly as a function of torque and speed), the optimal distribution may not be obtained by the standard practice. Finding a solution for the optimal freight distribution may also need to account for the cost of fueling and operator costs, particularly if the situation involves multiple vehicles not filled to capacity. The benefit is increased freight efficiency in transporting cargo from source to destination amongst a fleet of vehicles.

  • Patent number: 9658077
    Abstract: An apparatus remotely provides refueling management instructions for a vehicle. One or more initial vehicle parameters are determined, including an initial quantity of fuel, a plurality of route parameters including a starting point, an ending point and an estimated average fuel efficiency of the vehicle, and a plurality of refueling parameters including one or more refueling locations. The sufficiency of an initial quantity of fuel is evaluated in relation to the estimated average fuel efficiency and a distance to be traveled by the vehicle equal to a difference between the ending point and the starting point. One or more current vehicle parameters are interpreted at a first predetermined time, a refueling agenda is created, and an associated predetermined refueling amount at each of the identified one or more refueling locations is determined.

  • Patent number: 9440635
    Abstract: A velocity profile can be used in conjunction with vehicle operating condition data to determine a gear shift schedule that mitigates the amount of service brake effort required to slow a vehicle by making optimal use of engine speed, friction and engine brakes. The gear shift point drives the engine to a higher operating speed and greater frictional torque, slowing the vehicle, which can then coast to a desired speed. The gear shift point can be timed to minimize fuel consumption during the maneuver. Thus, a vehicle downshift event is created based on the transmission gear recommendation. The benefit is increased freight efficiency in transporting cargo from source to destination by minimizing fuel consumption and maintaining drivability.
