A system and method of estimating an available driving distance of an electric vehicle are provided. The method includes dividing a road into sections and receiving driving information from a vehicle traveling through each of the sections. Fuel efficiency data of the corresponding section is generated and vehicle condition information, and departure point and destination information is received from the target vehicle. Additionally, the method includes receiving real time meteorological information and road traffic situation information for each of the sections and reflecting the vehicle condition information of the target vehicle, the meteorological information and the road traffic situation information in the fuel efficiency data generated for each of the sections of the road from the departure point toward the destination. Estimated fuel efficiency and an estimated available driving distance of the target vehicle are then determined to be provided to vehicle driver.

System and method for estimating available driving distance of electric vehicle

A clutch control method for a vehicle includes steps of: calculating, by a controller, an estimated clutch torque by substituting a plurality of parameters, and a sensed stroke of a clutch actuator into a predetermined characteristic function; updating, by the controller, the parameters as new values by a prediction error method using a torque error, which is a difference between a reference clutch torque and the estimated clutch torque; calculating a desired stroke by substituting a desired clutch torque and the updated parameters into a predetermined characteristic inverse function; and driving the clutch actuator based on the calculated desired stroke to control the clutch by the controller. The plurality parameters represent physical properties of a clutch, and the predetermined characteristic function represents characteristics of a clutch transmission torque to a clutch actuator stroke. In addition, the predetermined characteristic inverse function represents a clutch actuator stroke to a clutch transmission torque.
