A motor vehicle includes a driver assistance system having a display unit and an evaluation unit for generating and displaying a refueling and/or recharging message which is generated in dependence on and independently of a fuel tank filling level or a state of charge of a battery and can be displayed for a defined time period. The evaluation unit is configured to check for the presence of conditions which are to be predefined, and given the presence of at least one condition, to generate a refueling and/or recharging message and to output the refueling and/or recharging message via the display unit.

A control device for a vehicle is provided. The vehicle includes an engine, an accessory, a continuously variable transmission, and a lock-up clutch. The control device includes an electronic control unit. The electronic control unit is configured to: when the load state is less than a predetermined value, control the speed ratio of the continuously variable transmission and the rotational speed of the engine such that the rotational speed of the engine during engagement of the lock-up clutch is kept at a first rotational speed; and when the load state is greater than or equal to the predetermined value, control the speed ratio of the continuously variable transmission and the rotational speed of the engine such that the rotational speed of the engine during engagement of the lockup clutch becomes a second rotational speed higher than the first rotational speed.

An electrified vehicle and associated method for controlling an electrified vehicle having an electric machine powered by a traction battery include an autoencoder trained with training data indicative of a remaining driving range of the traction battery. The trained autoencoder processes vehicle operating data to generate a reference data record and determines a value indicative of a similarity between the vehicle operating data and the reference data record. The autoencoder generates an output data record if the value indicative of the similarity is below a predetermined threshold value. The output data record may be used to display an alert or message to a vehicle occupant and/or control the vehicle to reduce power consumption to increase vehicle driving range.

One of objectives of the present invention is to derive a timing of energy supply in an automatic driving process with a better precision. A vehicle control system of the present invention comprises: an automatic driving control part, automatically performing at least one of velocity control and steering control of a vehicle, thereby automatically driving the vehicle to a set destination; a deriving part, deriving the energy predicted to be consumed during automatic driving on a guide path from a current position of the vehicle to the destination; and a judging part, judging whether the vehicle needs to be supplied with energy until the vehicle arrives at the destination based on the energy derived by the deriving part.

A method of determining an equivalence energy factor representing weighting applied between an infeed of energy of thermal origin and an infeed of energy of electrical origin, to minimize on an operating point overall energy consumption of a hybrid motor propulsion plant for an automotive vehicle including a heat engine and at least one electric motor powered by a battery. This factor is controlled in a discrete manner as a function of an instantaneous state of energy of the battery, and of an energy target, and as a function of the vehicle running conditions.

In a method performed by a control unit for controlling energy flows of a vehicle, where the vehicle includes a vehicle energy system which in turn includes a plurality of energy subsystems. Within each energy subsystem one form of energy is used. The energy subsystems are operationally connected by converters, wherein converters are devices converting at least one form of energy to another form of energy. By setting a price, limits for the converters converting energy between the energy subsystem the energy flows of the vehicle can be controlled by the control unit such that at least during period of times the order in which the energy subsystems of the vehicle is provided with energy can be changed.

A connected vehicle is able to communicate with a server. The server is configured to collect result data indicating traveling results of a plurality of vehicles. The connected vehicle includes a communication device configured to receive data from the server and a control device configured to calculate a travelable range of the connected vehicle. The control device is configured to calculate the travelable range based on data in which the travelable range is shorter among first data and second data. The first data is calculated based on traveling results of the connected vehicle and is correlated with the travelable range. The second data is calculated based on the result data collected in the server and is correlated with the travelable range.

Predefined route data for a driving route situated in front of the vehicle in the driving direction are provided. Further, at least one predefined predictive operating variable for the vehicle is provided. A three-dimensional model for a predefined environment of the vehicle is determined as a function of the route data. A graphic element is determined as a function of the three-dimensional model and of the at least one predictive operating variable. A head-up display of the vehicle has a predefined display field. The graphic element is displayed in the predefined display field. The graphic element is determined and displayed such that the graphic element is perceived by a viewer of the display field from a predefined viewing position with direct reference to the real environment of the vehicle.

Systems and methods of selective driver coaching are provided. Driver coaching systems learn the characteristics of a deceleration event. With the goal of increasing recouped energy while operating a hybrid electric vehicle (HEV), driver coaching systems predict when the HEV can begin coasting at the start of the deceleration event. In this way, the amount of time during which regenerative braking can be applied may be increased. Coaching cues are provided to the driver so that the HEV can be operated in way that achieves the goal of increasing recouped energy. However, engaging in excessive regenerative breaking can negate its advantages if the amount needed to reaccelerate the HEV to a cruising/steady speed is too great. Selective driver coaching provides coaching cues only if the operating efficiency of the HEV exceeds the operating efficiency of the HEV when controlled by the driver without coaching cues.

A method and a system for controlling a cruise control and a transmission in a vehicle over the course of a road section, wherein prior to the road section, the vehicle has applied coasting and utilizes the cruise control. A reference speed v.sub.ref utilized in the cruise control during the coasting is lowered to a lowest permitted speed v.sub.min defined for the road section if the lowering is deemed applicable. A comparison of a drive force F.sub.dd requested from an engine system in the vehicle with a threshold value F.sub.lim for the drive force is also carried out. The coasting is then suspended if the requested drive force F.sub.dd exceeds the threshold value F.sub.lim for the drive force.
