Abstract: A system for variably controlling braking energy regeneration by reflecting a compensation torque depending on a difference in deceleration if the difference in deceleration depending on a road gradient occurs due to an entry of a vehicle into a downhill road or an uphill road while the vehicle is coasting on a flatland at a defined deceleration depending on the regeneration step manually set by a driver using a paddle shift, the system may include an operation condition determiner, a grade resistance based FF controller, a deceleration based FB controller, and a coasting torque reflector.

Abstract: A system a vehicle having a wheel-driving motor is disclosed. The system includes wheel speed sensors for detecting speed of respective vehicle wheels, and a controller for controlling coast regenerative torque of the vehicle. The controller lowers coast regenerative torque based on wheel speed acquired detected using the wheel speed sensors. The controller is lowers coast regenerative torque based on speed difference among the wheels and based on change of wheel slip ratio.

Abstract: A method of improving braking performance through motor torque control of a vehicle includes: determining a relation between a vehicle wheel torque change amount and a driving acceleration change amount prior to a start of braking of the vehicle; calculating a target acceleration that is changed according to a driver's braking request when a driver presses a brake pedal to start the braking of the vehicle; detecting a real acceleration of the vehicle in real-time; comparing the real acceleration with the target acceleration; and compensating for a difference between the real acceleration and the target acceleration by increasing a regenerative braking amount through motor torque control when the real acceleration differs from the target acceleration.

Abstract: An apparatus and a method of controlling creep driving of an electric vehicle are provided to improve driving convenience and fuel efficiency. The apparatus is applied to an electric vehicle to which a ‘one-foot drive’ mode is applied to execute the creep driving and actively determine whether the creep driving is provided based on a vehicle speed.

Abstract: A hybrid vehicle and a braking method thereof are provided. The braking method includes determining a current braking situation based on a brake depth and calculating an amount of braking demanded by a driver corresponding to the brake depth when the current braking situation is a general braking situation. A regenerative braking command is generated to execute regenerative braking and a friction braking command to execute friction braking based on the amount of braking demanded by the driver.

Abstract: The present disclosure provides an apparatus and a method for controlling a vibration of a driving motor in a vehicle by generating a vibration reduction torque using gains that correspond to a torque variation and an RPM of a driving motor. The method includes storing a gain table in which gain values that correspond to a torque variation and a revolution per minute (RPM) of a driving motor in a vehicle are recorded. The torque variation of the driving motor and the RPM of the driving motor are detected. The gain values are determined using the detected torque variation and RPM of the driving motor based on the gain table and reducing. In addition, a vibration of the driving motor is reduced based on the determined gain values.
