Abstract
A vehicle control system has a battery, a vehicle alternator for charging the battery, a vehicle-alternator control device capable of controlling the vehicle alternator, and a battery current detection device. The battery current detection device has a battery current detecting means capable of detecting a charging/discharging current of the battery, a battery voltage detection means capable of detecting a voltage of the battery, a battery temperature detection means capable of detecting a temperature of the battery, a microcomputer, and a communication controller. The communication controller performs digital data communication to transfer digital control signals between the vehicle alternator and the battery current detection device. The vehicle alternator has a display unit to display the occurrence of abnormal information of those detection means transferred from the battery current detection device, the occurrence of a battery failure, and a disconnecting of a charging wire of the battery by using different display patterns.
