Abstract
A stop lamp lighting control device for an electric vehicle having an electric regenerative braking system, includes, a first calculation unit that converts a first deceleration threshold value to a first regenerative torque threshold value with a curb weight, a second calculation unit that converting a second deceleration threshold value to a second regenerative torque threshold value with a gross vehicle weight, a third calculation unit that calculates a third regenerative torque threshold value, and a determination unit that controls the stop lamp to be turned on when a regenerative torque value exceeds the first regenerative torque threshold value, the stop lamp to be turned off when the regenerative torque value is equal to or smaller than the second regenerative torque threshold value, and the stop lamp to be turned off when a given state continues.
