Abstract
An automotive generator control method includes inputting a current vehicle speed, an actual battery level, an actual battery temperature and an engine operating efficiency (S); calculating an optimal battery level by using a preset first mapping table, on a basis of the actual battery temperature and the current vehicle speed; taking a difference between the actual battery level and the optimal battery level as a target power-generation difference (S); calculating a target power-generation voltage by using a preset second mapping table, on a basis of the target power-generation difference and the engine operating efficiency (S); and outputting the target power-generation voltage (S). The automotive generator control method and control device can precisely control a power-generation voltage of a generator according to a current engine/vehicle working condition and a battery working condition, so as to achieve primary energy recovery of the generator in a highly efficient manner.
