  • Publication number: 20150019102
    Abstract: A system and a method of controlling vehicle starting may include a wheel speed sensor detecting a speed of at least one wheel among wheels of the vehicle, a vehicle speed detector detecting a vehicle speed, an acceleration detector detecting a vehicle acceleration, a vertical acceleration sensor detecting a vertical acceleration of the vehicle, a wheel torque detector calculating a wheel torque, an ambient temperature sensor detecting an ambient temperature, and a controller. The controller may calculate a wheel slip amount based on the speed of at least one wheel, the vehicle speed and the vehicle acceleration, determine whether a wheel slip occurs by comparing the wheel slip amount with a first predetermined wheel slip amount, determine a road state based on the ambient temperature and the vertical acceleration of the vehicle if the wheel slip occurs, and perform a starting control according to the road state.

  • Patent number: 8914207
    Abstract: A system may include: a data detector detecting data for a shift control; and a controller determining a short term driving tendency index and a long term driving tendency index of a driver based on the data, and controlling an engine or a transmission according to the short term driving tendency index or the long term driving tendency index of the driver, wherein the controller determines a difference between the short term driving tendency index and the long term driving tendency index, and controls the shift according a corrected driving tendency index that is corrected from the long term driving tendency index when an absolute value of the difference between the short term driving tendency index and the long term driving tendency index is greater than or equal to an absolute value of a reference index difference.
