This study reports the evaluation of the energy-saving effect of a longitudinal control algorithm based on the traffic states of electric vehicles. For realizing energy saving, the control structure should observe the various traffic states and reduce wasteful acceleration and deceleration. The longitudinal control for energy-saving proposed in this paper is realized using a velocity pattern generation algorithm and a velocity control algorithm. This paper proposes a longitudinal control algorithm to save energy in electric vehicles driven alongside ordinary vehicles on a street and evaluates the energy-saving effect of the control. In the experimental evaluation, the energy consumption was reduced by over 12% using the proposed longitudinal control algorithm as compared with the subjects who had driven properly. This study suggests that the proposed longitudinal control algorithm is effective in energy saving.
