摘要： Disclosed are a vehicle for generating an acceleration profile based on the acceleration cognitive characteristics of the human and a method of controlling the same. The method includes: receiving a manipulation amount of an accelerator pedal and calculating a first torque value, inserting the first torque value to a function that receives force and outputs acceleration feeling, generating a second torque value by inserting an output value of the function into a first filter for stabilizing the output value, generating a target torque value by inputting the second torque value to a second filter for stabilizing the second torque value, and generating a torque command based on the target torque value.

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 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 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.
