Vehicle control system capable of controlling electric-power generation state of vehicle alternator
First Claim
1. A vehicle control system comprising:
- a battery;
a vehicle alternator capable of charging the battery; and
a battery current detection device comprising;
a battery current detecting means that detects a charging current and a discharging current of the battery;
a battery voltage detection means that detects a terminal voltage of the battery;
a battery temperature detection means that detects a temperature of the battery;
a control means that controls the operation of the vehicle alternator based on detection results transferred from the battery current detecting means, the battery voltage detection means, and the battery temperature detection means; and
a communication means that performs a digital data transmission between the vehicle alternator and the battery current detection device; and
an abnormal state judgment means that judges whether or not an abnormal state of each of the battery current detecting means, the battery voltage detection means, and the battery temperature detection means has occurred, and transfers abnormal state information for informing the occurrence of abnormal state of each of the battery current detecting means, the battery voltage detection means, and the battery temperature detection means to the vehicle alternator through the communication means.

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.
