A control unit for controlling a heavy-duty vehicle, the control unit being arranged to receive ambient environment data from one or more environment sensors on the heavy-duty vehicle, and to predict an impact of the ambient environment on the motion of the heavy-duty vehicle, wherein the control unit is arranged to coordinate control of one or more motion support devices, MSDs, on the heavy-duty vehicle to compensate for the predicted impact of the ambient environment on the motion of the heavy-duty vehicle.

A control system for a vehicle. The control system comprises a force determination controller adapted to determine external load characteristics of external loads that currently act or are predicted to act on the vehicle. The control system is adapted to determine a resulting force vector to be acting on the vehicle, using the external load characteristics, in order to obtain a requested vehicle operation behaviour. The control system is further adapted to issue control information to one or more motion support devices of the vehicle in order to control the one or more motion support devices so as to generate the resulting force vector on the vehicle. The control system further comprises a feedforward controller adapted to receive wind information representative of a wind currently acting or predicted to be acting on the vehicle.

A method of calculating an engine torque request value for a vehicle includes a vehicle controller receiving an regeneration torque request value corresponding to a regeneration torque to be generated by an energy recovery mechanism. The vehicle controller further receives a desired acceleration value, and calculates the engine torque request value based on the regeneration torque request value and the desired acceleration value. The vehicle controller may then operate the engine in accordance with the engine torque request value.

A control system (202) can directly or indirectly measure force applied between a trailer (112) and a prime mover vehicle (102) coupled to the trailer. Based on the measured force, the control system can determine an operational state of one or more features of the trailer. For example, static resistance, rolling resistance, and/or acceleration rate of the trailer can be measured while applying a specific braking actuation level to the service air brakes of the trailer. Based at least in part on the measured static resistance, rolling resistance, and/or acceleration rate, an operational model (206) for actuation of the service air brakes can be applied. In some examples, the control system can be part of the prime mover vehicle, for example, an autonomous vehicle.

Path specific rolling resistance is determined in a method including: receiving, from a first source, first rolling resistance data of a first set of road surface portions of a corresponding first set of times; receiving, from a second source, second rolling resistance data of a second set of road surface portions of a corresponding second set of times; determining, using any of the first rolling resistance data and the second rolling resistance data, a path specific rolling resistance for a given path including one or more of the road surface portions selected from the first and second set of road surface portions; and providing at least one target vehicle with the path specific rolling resistance or a derivative of the path specific rolling resistance.

An apparatus for providing a distance to empty of a green vehicle includes a motor. A battery provides a driving voltage to the motor and includes a plurality of cells. A motor controller is configured to control driving and a torque of the motor. A battery manager is configured to control charge and discharge of the battery. A vehicle controller is configured to integratedly control the motor controller and the battery manager according to a state of the vehicle through a network. The vehicle controller calculates a first distance to empty (DTE) by using a past fuel efficiency, calculates a second DTE by using designated route driving information, and calculates a final DTE by using the first DTE and the second DTE.

A method of estimating distance to empty (DTE) for a vehicle includes, in response to detecting an energy loss condition expected to be present during an initial portion of a drive cycle for a period of time needed for a current temperature or pressure associated with the vehicle to achieve a steady state, outputting a DTE. The DTE is based on an amount of drive energy available and an energy loss factor associated with the energy loss condition that accounts for conversion of some of the drive energy to heat as the current temperature or pressure increases to the steady state.
