摘要： A hybrid electric vehicle is capable of preventing over-temperature of an electric motor when the vehicle travels using only the output of the electric motor without driving an engine while passing through a specific zone using route information to a destination and a motor control method for the same. The motor cooling control method includes, when determined that a specific zone related to discharge of exhaust gas is present on a traveling route, determining a target motor temperature to be reached when entering the specific zone, determining a cooling distance necessary to reach the target motor temperature, determining the time at which to start cooling control using the determined cooling distance, and restricting a motor-driving range from the time at which to start the cooling control until entering the specific zone.

摘要： Disclosed are a method of controlling a mode transition in order to predict a driver's required torque to reduce non-driving fuel loss, and a hybrid vehicle for performing the method.In particular, the method of controlling a mode transition of a hybrid vehicle may include: determining whether to change a first mode to a second mode based on a first torque; determining a second torque expected to be generated at a near-future time after a current time; determining whether or not an engine clutch engagement is possible at the near-future time based on the second torque or a predicted acceleration; and performing the change from the first mode to the second mode when the mode change from the first mode to the second mode is determined and the engine clutch engagement is possible.

摘要： A hybrid vehicle and a control method are provided. The method of controlling a hybrid vehicle including a motor, an engine, and an engine clutch disposed between the motor and the engine includes determining whether to enter a first mode in which both the engine and the motor operate without engagement of the engine clutch, based on at least a first condition related to an accelerator pedal and a second condition related to a required torque condition, determining torque of the motor in consideration of at least required torque upon determining entry into the first mode, and determining an operating point of the engine based on engine generation power to be supplied to the motor with power of the engine.

摘要： A passenger compartment of a hybrid electric vehicle is heated without operating an engine when passing through a specific zone using information about a route to a destination and a heating control method. The heating control method includes, when determined that a specific zone related to discharge of exhaust gas is present on a traveling route, determining a target coolant temperature, which is a coolant temperature to be reached when entering the specific zone, determining a coolant temperature increase distance necessary to reach the target coolant temperature, determining the time at which to start temperature increase control using the determined coolant temperature increase distance, and operating an engine from the time at which to start the temperature increase control until entering the specific zone.

摘要： A turning control system of a vehicle includes: a database storing road information; a sensor part to detect a steering angle of a vehicle, a wheel speed of the vehicle, whether the vehicle is accelerated, whether the vehicle is braking, and whether a speed gear of the vehicle is shifted; and a controller that determines whether the vehicle enters a turning section based on one or more pieces of the information detected by the sensor part and the road information stored in the database. In particular, when the vehicle is entering the turning section, the controller sets a target speed of the vehicle and controls a speed of the vehicle to be decelerated to the set target speed.

摘要： A hybrid vehicle and a method of calibrating a traveling direction of the hybrid vehicle are disclosed. The method of calibrating a traveling direction of a hybrid vehicle including a transmission not having a reverse gear includes: when an abnormality of a motor speed sensor is detected, calculating a difference between at least one of a first moving distance calculated based on sensor information during a predetermined time or a second moving distance calculated based on output torque and a third moving distance calculated based on a vehicle speed by a controller for controlling output torque; when an absolute value of the calculated difference is greater than a preset error reference, reversing the traveling direction recognized by the controller; and controlling a powertrain in response to a transmission lever state.

摘要： An eco-friendly vehicle and a launch control method for an eco-friendly vehicle reduces an unpleasant secondary launch effect based on a gear alignment state of a transmission in a specific situation. The launch control method includes: determining a first condition for enabling a preset stop control when the first condition is satisfied; turning off a control for generating a creep torque of a motor when a brake is released; controlling a transmission in an open state and enabling the control for generating the creep torque; and when a second condition for revolutions per minute (RPM) of the motor is satisfied, controlling the transmission in a lock state through a slip state.
