<p>PURPOSE:To prevent when there is a too large demand for power degradation of a function due to power supply shortage, for example, decrease of illumination of a head light or decrease of wind force of a blower to avoid giving the impression that an automobile lacks power. CONSTITUTION:Electric demand equipment is divided into a higher priority group and a lower priority group. The higher priority group includes equipment whose functions are degraded when power is in short supply, for example, a head light or blower. The lower priority group includes equipment whose functions are not substantially degraded under the same conditions, for example, a rear defogger or seat heater. If there is a demand for power, the total demand (W1+W2) is first determined. If the value exceeds the allowable power Ws, the excessive electric energy W0 is calculated (step 104). The second demand equipment group is driven and controlled so that consumed power equals the demand W2 of the second demand equipment group minus the excessive electric energy W0 (step 107, 108)</p> |
