  • Publication number: 20200172109
    Abstract: A vehicle having an electric motor and a driving control method for the same are provided. The method of controlling regenerative braking torque of a motor of a vehicle, which is configured to transmit power of the motor to opposite side wheels via a differential gear, includes determining whether a curved road is present ahead of the vehicle. When the curved road is detected, the load to be applied to an inner wheel of the opposite side wheels is determined depending on lateral weight shifting on the curved road based on at least one of the curvature of the curved road or the vehicle speed. A grip of the inner wheel is determined based on the determined load and a regenerative braking limit is corrected based on the determined grip.

  • Publication number: 20190176822
    Abstract: A vehicle speed-limit control method is provided. The method includes determining whether a speed-limit control inactivation condition is satisfied by accelerator pedal engaged when speed-limit control is activated. In response to determining that the inactivation condition is satisfied, a candidate value of an accelerator pedal sensor (APS) and a candidate gear shift stage are determined and a speed margin is determined based on the candidate value of the APS, the candidate gear shift stage and a vehicle speed. The speed margin is compared with a predetermined threshold. The candidate gear shift stage is determined as a transition gear shift stage and the candidate value of the APS is determined as a transition value of the APS when the speed margin is equal to or greater than the threshold. The vehicle is operated based on the transition gear shift stage and the transition value of the APS.
