Embodiments of the present invention provide a controller for indicating a residual driving range available in a battery of an electric vehicle. The controller is operable in a first mode wherein it instructs the output means to display an output indicative of the total amount of energy remaining in the battery and a second mode wherein it instructs the output means to display an output indicative of an amount of energy that may be used without causing the total amount of energy stored in the battery to reduce below an amount required to undertake a predetermined journey. The controller is operable to switch from the first mode to the second mode upon receipt of a user input via said second input means. Advantageously, the second mode may display an amount of energy that can be used in a leisure driving session.

Further, the contribution index of each of the individual control parameters may be identified. Further, based on the estimated emission value and the contribution index, aggregated emission value corresponding to the exhausted emission from the engine for particular trip may be calculated.

A method for creating an emissions model of an internal combustion engine. The method begins with a provision of a plurality of measurement series at an internal combustion engine.

A system and method of calculating a vehicle DTE are provided to calculate a fuel efficiency of each vehicle drive mode, and display a more accurate DTE of each drive mode. The method includes when a driver selects a drive mode and a drive distance of the selected drive mode is accumulated while a vehicle is being driven in the selected mode, collecting drive data including an accumulated drive distance of each drive mode, and fuel efficiency information of each drive mode. A final fuel efficiency of each drive mode is calculated using a drive distance of each drive mode, a consumption energy of each drive mode or a fuel efficiency of each drive mode, and a learning fuel efficiency. A DTE of each drive mode is then calculated based on the calculated final fuel efficiency of each drive mode.

A method is disclosed for monitoring the functions of a friction clutch which is arranged in a vehicle between a drive motor and a compressor of a compressed air supply system and which can be disengaged and engaged pneumatically. In a delivery mode of the compressor, at least one operating parameter is detected by sensor and evaluated in an electronic control unit. When a slipping condition of the friction clutch is identified, a value for a cut-off pressure of the compressor stored in the electronic control unit is reduced. When a slipping condition has been identified, the delivery mode of the compressor is ended by disengagement of the friction clutch, and a warning signal and/or warning information is outputted.

Based on a set of planned control parameters defining a planned path for a vehicle, a set of reference control parameters corresponding to the set of planned path control parameters are identified. Optimized controller inputs associated with the identified set of reference control parameters, the set of planned control parameters, and operation noise data are input to a vehicle dynamics model that outputs a vehicle state model. Based on the vehicle state model, an actual path for the vehicle and an operating range for the actual path are determined. The planned path is determined to be one of verified or unverified based on the operating range.

An ability of a power transmission device to transfer electric charge in a power-transmission area at a particular point in time is identified. The ability comprises a threshold number of vehicles to which the power-transmission device can transfer electric charge with at least a threshold efficiency. A predicted number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time is calculated. The number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time is adjusted based on a determination that the predicted number of vehicles is not bound by the threshold number of vehicles.
