An information processing device includes a controller that is configured to: acquire driving behavior information as an indication of prudence of a driver in driving a vehicle, acquire a vehicle avatar corresponding to the vehicle, the vehicle avatar having a basic personality set thereto according to information about the vehicle, create a message according to the basic personality of the vehicle avatar based on the driving behavior information, and output the message, that is created, as an utterance of the vehicle avatar.

A control device controls an instrument configured to indicate a state of a moving body. An instrument has a first object having a line shape or band shape that is continuously visually recognized, a second object indicative of a present value of an output index that is an index relating to an output energy amount, and a third object indicative of a present value of a regeneration index that is an index relating to a regenerative energy amount. A partial region on the first object is formed with an output region in which the present value of the output index is indicated by a position on the region, and a region different from the output region on the first object is formed with a regeneration region in which the present value of the regeneration index is indicated by a position on the region.

A work vehicle includes a main key having an ON position for enabling electric power supply to electric devices and an OFF position for stopping the electric power supply to the electric devices, an engine information acquiring section configured to acquire engine information including a fuel supply amount from an engine controlling section that calculates the fuel supply amount to the engine, a momentary fuel consumption amount calculating section configured to calculate a momentary fuel consumption amount based on the engine information, a total fuel consumption amount calculating section configured to calculate, based on the engine information, a total fuel consumption amount which is a total amount of fuel used from an ON state to an OFF state of the main key, and a display controlling section configured to selectively display the momentary fuel consumption amount and the total fuel consumption amount on a display unit.

A method and apparatus for evaluating the driving of a vehicle performing a journey on a road network is disclosed. The method comprises determining a fuel usage rate and an engine speed of a vehicle, and determining when the vehicle is coasting based upon at least one of the fuel usage rate and the engine speed of the vehicle. An acceleration of the vehicle, when the vehicle is determined to be coasting, is compared with a predetermined reference acceleration, and an application of braking during the coasting is determined based on the result of the comparison. A method and apparatus is also disclosed for determining a score indicative of the relative amount of time for which the vehicle is coasting without braking during a journey.

A method for selecting an operating mode for a vehicle which has at least two operating modes. Graphics data of a graphic user interface are generated and output, wherein the graphic user interface includes a background display and at least two selectable control buttons, wherein the control buttons are each assigned to an operating mode of the vehicle. A selection of a control button is detected, and a control signal is generated and transmitted to a control device of the vehicle as a function of the operating mode assigned to the selected control button. The background display includes a display of a vehicle surface, wherein the displayed vehicle surface is formed as a function of the operating mode which is selected at the current time. Also disclosed is a system for selecting an operating mode for a vehicle.

A display unit for a hybrid vehicle having at least one internal combustion engine-powered drive and at least one electric motor-powered drive, includes the following components: a first electronic determining module for determining the proportion of the current or averaged total fuel consumption used for charging the energy accumulator for the electric motor-powered drive, and/or for determining the proportion of the current or averaged total fuel consumption used to drive the hybrid vehicle; and a first display element for displaying at least this determined charge-fuel proportion and/or this determined drive-fuel proportion, in addition to the total fuel consumption.

One way to improve fuel efficiency of a vehicle is to detect the vehicle operational shortcomings related to fuel consumption by determining whether fuel used during operation of the vehicle is normal fuel use or wasted fuel use. Considerations of idling, speeding and inappropriate gear shifts are some ways to measure the amount of fuel wasted due to operator shortcomings. Communicating this information to the operator in real-time so adjustments can be made will improve vehicle fuel efficiency. These techniques are applicable to tracking employment of other driving best practices as well.

An apparatus comprising an interface, a memory and a processor. The interface may be configured to receive sensor data samples during operation of a vehicle. The memory may be configured to store the sensor data samples over a number of points in time. The processor may be configured to analyze the sensor data samples stored in the memory to detect a pattern. The processor may be configured to manage an application of brakes of the vehicle in response to the pattern.

A vehicle computer system (e.g., on-board vehicle computer system) obtains a fuel economy performance goal for a vehicle (e.g., an engine speed goal or a vehicle speed goal) that is based on a configuration of the vehicle; calculates a count of events in which a current value exceeds the goal; compares the count of events with a threshold count; and generates one or more notifications based at least in part on the comparison (e.g., for display on an operator interface). The vehicle computer system also calculates an engine speed and a vehicle speed score for a driver of the vehicle based at least in part on comparisons of current speeds with the speed goals. Scoring and other data may be displayed or stored for further processing.

A coasting control method of an eco-friendly vehicle includes steps of acquiring deceleration event information and road gradient information in front of a vehicle during driving, by a controller in the vehicle, determining target vehicle speed in a deceleration event in consideration of road gradient based on the deceleration event information and the road gradient information, by the controller, determining expected vehicle speed while the vehicle is decelerated in a coasting state, based on current vehicle speed, by the controller, determining a start location for starting coasting based on target vehicle speed in consideration of current vehicle speed of the vehicle and the road gradient and expected vehicle speed at a target location as a deceleration event location, by the controller, and operating an information provider for coasting guidance and coasting induction to a driver at a start location, by the controller.
