    摘要： A driving force control apparatus for a vehicle includes a first sensor that detects an output command supplied to a power source, a second sensor that detects an operating condition amount of a vehicle and a controller. The controller calculates a basic command value of an output of the power source based upon the output command from the first sensor, calculates a reference model command value based upon the basic command value and transmission characteristic of a response of reference model, calculates a correction value from a deviation between the reference model command value and a predetermined frequency component corresponding to a vibration of a vehicle driving system extracted out of the operating condition amount of the vehicle, and calculates a target command value based upon the basic command value and the correction value to control the torque of the power source.

    摘要： Disclosed are an apparatus for estimating a bounce speed of a vehicle and a method thereof. The apparatus includes an acceleration sensor that detects an acceleration of the vehicle, a front wheel speed sensor that detects a wheel speed of a front wheel of the vehicle, a rear wheel speed sensor that detects a wheel speed of a rear wheel of the vehicle, and a controller. The controller determines a wheel acceleration of the front wheel based on the wheel speed of the front wheel, determines a wheel acceleration of the rear wheel based on the wheel speed of the rear wheel, and estimates the bounce speed of the vehicle. The bounce speed of the vehicle is estimated based on the acceleration of the vehicle, the wheel acceleration of the front wheel, and the wheel acceleration of the rear wheel.
