PROBLEM TO BE SOLVED: To control appropriately turning on/off of a stop lamp when operating an electric type regenerative braking device of an electric vehicle.SOLUTION: A vehicle weight estimation portion 15 calculates estimated vehicle weight W determined by estimating actual vehicle weight of an electric vehicle using required torque (=driving torque). A deceleration calculation portion 16 calculates estimated deceleration D determined by estimating deceleration of the electric vehicle using vehicle velocity, regenerative torque and the estimated vehicle weight. A stop lamp turning-on determination portion 17 compares with each other and determines the estimated deceleration D, stop lamp turning-on deceleration thresholds and stop lamp turning-off deceleration thresholds; and turning on or turning off of a stop lamp 3 is controlled on the basis of the comparison and determination results.

    【課題】電動車両の電気式回生制動装置の作動時に、適切にストップランプの点灯消灯制御をする。【解決手段】車両重量推定部15は、要求トルク(=駆動トルク)を用いて電動車両の実際の車両重量を推定した推定車両重量Wを演算する。減速度演算部16は、車速と回生トルクと推定車両重量を用いて電動車両の減速度を推定した推定減速度Dを演算する。ストップランプ点灯判定部17は、推定減速度Dとストップランプ点灯減速度閾値及びストップランプ消灯減速度閾値とを比較判定し、この比較判定結果に基づきストップランプ3の点灯又は消灯制御をする。【選択図】図1
