摘要： An engine start controller for a hybrid vehicle and a method thereof are provided. The engine start controller includes a hybrid starter generator (HSG) that is connected to an engine by a belt, a sensor that is configured to measure an HSG speed, and a processor that applies a starting torque to the HSG. When starting the engine, the processor calculates an HSG speed estimated based on the applied starting torque and calculates an amount of slip of the belt using the HSG speed. In addition, the processor calculates a torque change rate correction value based on the calculated amount of slip, and corrects a rate of change rate in the starting torque based on the torque change rate correction value.

摘要： A system and method for estimating a wheel speed of a vehicle are provided. The system includes a wheel speed sensor that detects a rotation speed of a wheel of the vehicle and a longitudinal acceleration sensor that detects a longitudinal acceleration of the vehicle. A controller converts the longitudinal acceleration to a wheel acceleration, compensates for the converted wheel acceleration based on a compensation value obtained using wheel speed information, integrates the compensated wheel acceleration, and calculates a wheel speed estimation value based on the integrated wheel acceleration.

摘要： A vehicle is controlled such that a driving mode of the vehicle is automatically selected, where the vehicle can be a Plug-In Hybrid Electric Vehicle (PHEV). The vehicle automatically selects an optimum driving mode from among various driving modes capable of being selected by the PHEV according to a driving situation based on a destination established by a driver who uses a navigation system, or recommends various driving modes to the driver, resulting in increased convenience of use. Through selection of an appropriate driving mode, the vehicle can be driven with superior fuel efficiency, resulting in increased driving efficiency.

摘要： A plug-in vehicle is provided which prevents impossibility of driving even when a charging connector is not connected to the vehicle and a method of controlling the same. The method includes determining whether the vehicle is stopped and determining whether recognition of a connection of the charging connector to the vehicle is enabled. Additionally, the method includes determining whether a charging inlet door is open or closed, in response to determining that recognition of the connection of the charging connector to the vehicle is disenabled, and executing transition of the vehicle from a first state restricting generation of driving power to a second state permitting generation of driving power when the charging inlet door is closed.

摘要： A shift control method and system for a hybrid vehicle are provided to increase the recovery rate of regenerative energy, improve the fuel efficiency, and minimize the loss of the fuel efficiency upon reaccelerating after braking. The method include: acquiring in real-time information regarding a transmission input speed during driving and sensing a brake pedal operation. In addition, whether a road driving situation or a driver tendency corresponds to a skip shift allowable condition is detected when the brake pedal operation is sensed. A target shift stage to which a skip shift of two or more stages is performed is selected from a current shift stage based on the transmission input speed in real-time, when the road driving situation or the driver tendency corresponds to the skip shift allowable condition. Then a transmission is operated to shift to the selected target shift stage.
