Abstract: The optimum headway distance setting method may include determining whether or not to stop the speed adjustment operation for a vehicle by a driver of the vehicle by a control unit in the state detecting a front vehicle 1F which is traveling in front of the vehicle; determining whether or not to be stabilization of a headway distance between the vehicle and the front vehicle by the control unit when the speed adjustment operation for the vehicle is stopped; setting the optimum headway distance configured to set the stabilized headway distance as an optimum headway distance according to a traveling propensity of the driver by the control unit, and stores the optimum headway distance in the control unit.

Abstract: A system variably controls braking energy regeneration in a vehicle by reflecting a compensation torque depending on a difference in deceleration based on a road gradient when the vehicle travels over a downhill section or an uphill section of a road. The system includes a longitudinal sensor to receive the road gradient and compare the road gradient to a specific grade, and then compensate for the road gradient using a grade resistance value and a deceleration based value depending on a difference between deceleration manually set by a driver using a paddle shift and an actual vehicle deceleration. The system may include a controller to output a coasting torque as a correction torque that is a sum of the grade resistance value and the deceleration based value.

Abstract: Disclosed are a vehicle equipped with an electric motor, which is capable of preventing damage to a mechanical axle-fixing device when a parking range is selected under a specific condition, and a parking control method therefore. The parking control method includes calculating output torque of the electric motor to stop the vehicle when a parking (P) range is selected in the situation in which a specific condition is satisfied, controlling the electric motor in response to the output torque, and activating a driving shaft fixing unit when the vehicle is stopped by the controlling.

Abstract: An apparatus for controlling energy regeneration variably capable of performing a variable control based on a deceleration event discrimination using a map information input as well as a driver's operation may include a controller configured to change a preset energy regeneration stage variably to a corresponding regenerative braking control by sensing an event for an energy regeneration stage and perform the corresponding regenerative braking control, and a generator configured to generate power according to the regenerative braking control.

Abstract: A vehicle in which a shift lever of a Shift-by-Wire (SBW) type is used, the vehicle may include an inputter configured to receive pressing force of an acceleration pedal of the vehicle, a shift command to a P-stage of the shift lever, and gradient information related to a road on which the vehicle drives; a controller configured to: when the pressing force of the acceleration pedal of the vehicle is generated and the shift command to the P-stage is input to the controller, determine a gradient load torque and an acceleration torque of the vehicle, and limit a driver's requested torque based on the determined gradient load torque and the determined acceleration torque; and a driving device connected to the controller and configured to shift the shift lever to the P-stage when the driver's requested torque is limited.

Abstract: A system for variably controlling braking energy regeneration by reflecting a compensation torque depending on a difference in deceleration if the difference in deceleration depending on a road gradient occurs due to an entry of a vehicle into a downhill road or an uphill road while the vehicle is coasting on a flatland at a defined deceleration depending on the regeneration step manually set by a driver using a paddle shift, the system may include an operation condition determiner, a grade resistance based FF controller, a deceleration based FB controller, and a coasting torque reflector.

Abstract: A vehicle charging control method is provided. The method includes recognizing scheduled charging information predetermined for vehicle charging and detecting charging equipment connected to the vehicle. Whether a scheduled charging is performed is determined based at least on whether charging information from the charging equipment corresponds to the scheduled charging information. Whether an automatic charging is performed is determined based at least on predetermined user set-up information when the charging information deviates from the scheduled charging information. A charging operation, including the scheduled charging and the automatic charging is then performed for the vehicle.
