A method for assisting a power-intensive driving maneuver of an ego vehicle propelled by an electric motor fed from an energy-storage device includes predicting a power-intensive driving maneuver of the ego vehicle, ascertaining a peak-power profile that is needed for a complete execution of the predicted driving maneuver, and determining an available propulsive power of the ego vehicle. The method further includes ascertaining whether the available propulsive power is sufficient for the peak-power profile and, if the available propulsive power is sufficient for the peak-power profile, indicating a recommendation for execution of the predicted driving maneuver. If the available power is not sufficient for the peak-power profile, the method further includes ascertaining whether the available propulsive power is sufficient for a restricted peak-power profile that is needed for a restricted execution of the predicted driving maneuver, indicating a recommendation for restricted execution of the predicted driving maneuver if the available propulsive power is sufficient for the restricted peak-power profile, and indicating a recommendation for non-execution of the predicted driving maneuver if the available propulsive power is not sufficient for the restricted peak-power profile.

A driving assistance method for assisting a power-intensive driving maneuver of a subject vehicle includes predicting the power-intensive driving maneuver of the subject vehicle, and determining whether driving maneuver criteria, which comprise at least one energy criterion and at least one traffic criterion, are satisfied for the predicted power-intensive driving maneuver. Determining if the at least one energy criterion is satisfied includes determining a peak power profile required for a full execution of the predicted power-intensive driving maneuver, determining an available drive power of the subject vehicle, and evaluating whether the available drive power is sufficient for the peak power profile, wherein the at least one energy criterion is satisfied if the available drive power is sufficient for the peak power profile. Determining if the at least one traffic criterion is satisfied includes detecting a traffic situation, which comprises at least one traffic condition and/or a route topology, in the surroundings of the subject vehicle, and evaluating whether the predicted power-intensive driving maneuver can be fully executed in the detected traffic situation, wherein the traffic criterion is satisfied if the predicted driving maneuver can be fully executed in detected traffic situation. The method further includes displaying a result of determining whether the driving maneuver criteria are satisfied for the predicted power-intensive driving maneuver.

An electric vehicle including an electric motor and a battery system to provide electrical power to the electric motor. A first input device, when actuated, provides a first input representing a command to propel the electric vehicle. A second input device, when actuated, provides a second input for initiating a boost operating mode. A controller is operative to control a permitted rate of change of a selected operating parameter of the electric motor. The controller, in a normal operating mode, operates the electric motor according to a first rate of change for the selected operating parameter in response to the first input, and in a boost operating mode, operates the electric motor according to a second rate of change, greater than the first, for the selected operating parameter for a limited period of time in response to the first input.

A method of controlling a vehicle is disclosed, the method comprising steps of: determining a saturated reference yaw moment based on an initial reference yaw moment and a total wheel torque demand, taking into account operational limits of the vehicle; determining initial torque allocations for each one of a plurality of wheels of the electric vehicle based on the saturated reference yaw moment; and for each one of the plurality of wheels, checking whether the initial torque allocation for said wheel exceeds a corresponding wheel torque limit for said wheel. In response to a determination that the initial torque allocation for a first wheel exceeds the corresponding wheel torque limit, and that the initial torque allocation for a second wheel on the same side of the vehicle is less than the corresponding wheel torque limit, the initial torque allocations are revised by increasing the torque allocation to the second wheel. The electric vehicle can then be controlled to apply the revised torque allocations to the plurality of wheels. Apparatus for controlling a vehicle is also disclosed.

The invention relates to a management system and method for the heat treatment of at least one element of a drive train of an electric or hybrid motor vehicle so as to optimize the performance of the vehicle for intensive use being carried out or planned.

The invention relates to an arrangement for supplying a rail vehicle with electrical energy. One electrical machine is allocated to each of at least two internal combustion engines for generating electrical energy. A common controller is designed to start the internal combustion engines individually as required. At least one pre-heating device is designed to pre-heat the internal combustion engines before a start. A temperature detection device is thermally coupled to the internal combustion engines. The controller is designed, during an operation of one of the internal combustion engines, to start another of the internal combustion engines if, due to cooling of the other internal combustion engine, a temperature of the other internal combustion engine detected by a temperature identifying device reaches or exceeds a temperature threshold.
