Automatic start device when battery dark current is excessive and its method

摘要

The present invention relates to a speed control apparatus and method by self-diagnosis when the vehicle performance is abnormal, the current amount detection unit 10 for detecting the current amount of the vehicle battery, and outputs the signal according to the current, the position of the shift lever, The shift lever position detection unit 20 for outputting the electric signal according to the detection, the parking brake detection unit 30 for detecting the position of the parking brake, and outputs the electric signal according to the current amount detection unit 10 and In response to the signal output from the shift lever position detecting unit 20 and the parking brake detecting unit 30 being input, when the battery is excessively discharged, a signal for starting up and a signal for supplying power to the engine controller are provided. The control unit 40 to output, and operates according to the start signal output from the control unit 40, the start device 50 to be started without the operator's key operation, and the signal output from the control unit 40 D. The engine control device 60 starts operation, and if the vehicle is left without driving for a long time for various reasons, such as waiting for export shipment, it detects a discharge state and automatically starts the battery by starting each time. The present invention relates to an automatic starting device and a method for overcharging a battery dark current which prevents a vehicle battery from being discharged.
