Abstract

The invention relates to an over current sensing device and an over current sensing method. The over current sensing device of the invention is characterized in that an over current is sensed according to vehicle loads, and power source control is only exerted on loads sensing the over current. According to the over current sensing device and the over current sensing method, short circuits can be prevented in a vehicle or electronic devices can be prevented from being damaged by the over current, and the over current sensing device and the over current sensing method are advantaged in that side effects and subsequent accidents can be prevented through dispersed power source control of all modules. The phenomenon that inconvenience is brought to a driver or possibility of accidents are caused because other electronic devices cannot be used when an overall power source is turned off can be prevented. Besides, damage caused by storage battery discharging can be prevented, and the service life of a storage battery can be prolonged.

Description

technical field

[0001] The present invention relates to an overcurrent sensing device and method, and more specifically, to a device and method for sensing overcurrent according to the load of a vehicle. Background technique

[0002] The previous battery sensor monitors the voltage, current, and temperature of the vehicle battery, and transmits the monitored information to the engine controller as the main controller through LIN (Local Interconnect Network) communication. state, to control the alternator (Alternator) in order to adjust the vehicle load based on the grasped results.

[0003] That is, if figure 1 As shown, the conventional IBS vehicle system includes a vehicle battery, IBS (Intelligent Battery Sensor, Intelligent Battery Sensor), and an engine controller (Energy Management Controller). As a representative load, it includes G (Generator), that is, a generator, an alternator, etc. M (Motor), that is, MDPS, ABS, AirSUS and other high-current motor-driven loads,...
