A vehicle and a control method are capable of generating compressed air using a motor of a hybrid vehicle so as to perform cleaning/care of the hybrid vehicle, without an additional or separate device. The vehicle includes an engine including an intake pipe provided to suck outside air and an exhaust pipe provided to discharge inside air, an opening degree control valve provided at a rear end of the exhaust pipe, and a motor configured to generate power for driving a wheel and configured to drive a piston of the engine by using a portion of the power. In response to the opening degree control valve being in a closed state, and in response to the engine being in a non-combustion state, compressed air is generated in the exhaust pipe by driving the piston of the engine with the power of the motor.

Vehicle and control method for generating compressed air by motor

A vehicle includes a power supply including a battery, a display, a storage configured to store a power matching data, and a fuel efficiency matching data, and a controller configured to determine driving power supplied by the battery, determine a current driving fuel efficiency corresponding to a reference weight based on the driving power and the power matching data, determine the current weight of the vehicle, determine a first fuel efficiency based on an accumulated driving fuel efficiency accumulated from a previous charging time point to a current charging time point and the current driving fuel efficiency at the current charging time point, determine a second fuel efficiency based on the fuel efficiency matching data and the first fuel efficiency corresponding to each of the existing weight and the current weight, determine the estimated driving distance of the vehicle based on the charging capacity of the battery and the second fuel efficiency, and output the estimated driving distance to the display.

Vehicle and control method thereof

Disclosed are a vehicle and method for managing a battery for vehicle. The vehicle includes a battery configured to be charged and discharged while connected to a charger; and a controller configured to charge the battery by distributing charging current for the battery with the foremost priority if the charging current for the battery is smaller than consumption current, and distribute the consumption current after a state of charge (SoC) of the battery reaches a target charging level.

Vehicle having controller for managing battery and method for the same

A slow charging method of a vehicle and an on-board charger using the same are provided that improve charging efficiency and thus save a charging cost by adjusted charging output of the on-board charger based on temperature thereof. The method includes detecting, by a controller, a charging request and detecting temperature of the on-board charger in response to detecting the charging request. The controller is configured to determine whether the temperature of the on-board charger is within a predetermined temperature range and adjust charging an output of the on-board charger to a predetermined value when the temperature of the on-board charger is within the predetermined temperature range. The controller is then configured to charge a battery of the vehicle with the adjusted charging output of the on-board charger.

Slow charging method and on-board charger for environmentally-friendly vehicle using the same

A system and method for assisting a driver are provided. The method includes receiving, by a controller, vehicle traveling information and calculating a first distance between a present vehicle position and an end node. In addition, the controller is configured to calculate a second distance between the present vehicle position and a preceding vehicle based on the receiving information and calculate a third distance in which coasting is available until a present vehicle speed reaches a predetermined target speed. The method further includes determining, by the controller, whether coasting is available based on the first distance, the second distance, the third distance in which coasting is available, and a present vehicle speed of the vehicle, and outputting, when coasting is available, a message that instructs coasting.

System and method for assisting driver

A system and a method of assisting a driver in driving an electric vehicle in a more environmentally efficient manner are disclosed. In particular, an information collecting section collects information operating the electric vehicle and a control logic section generates control logic and models related to route calculation to a destination and operation of the electric vehicle based on the collected information. A route setting section calculates a plurality of travel routes based on the control logic and the model related to the route calculation and sets an optimum travel route having the highest energy efficiency among the plurality of travel routes. A vehicle driving controller monitors the vehicle state and controls driving of the electric vehicle based on the control logic and the model related to the driving of the electric vehicle when the electric vehicle travels along the optimum travel route set by the route setting section.
