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.

Abstract: A system and method of controlling regenerative braking of an eco-friendly vehicle are provided. The system eliminates a motor over-temperature state during regenerative braking, effectively prevents a chattering phenomenon in which regenerative braking torque is repeatedly increased and reduced after the motor over-temperature state, and consequently, improves the braking safety and operability of the vehicle. A torque output rate for motor regenerative braking torque limitation is determined from a current motor load and motor temperature using setting information when a motor over-temperature state is detected. Then, a final regenerative braking torque is determined by multiplying a motor regenerative braking torque, calculated from information including battery chargeable power and a driver braking operation value, by the determined torque output rate. Thereafter, regenerative braking of a motor is adjusted based on the determined final regenerative braking torque.
