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： 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： method of controlling torque of a vehicle driving device is provided. The method includes estimating speed of a driving system of a vehicle from vehicle driving information collected from the vehicle and calculating speed difference between actually measured speed of the driving system and the estimated speed of the driving system. A nominal rate limit value is determined according to the vehicle driving information and a required real-time rate correction amount is determined according to the calculated speed difference. A torque command variation is determined based on the determined nominal rate limit value and the determined required real-time rate correction amount. A torque command after correction in a previous control period is corrected by the determined torque command variation to determine a torque command after correction in a current control period.
