摘要： PROBLEM TO BE SOLVED: To enable quicker determination of overcurrent anomaly in an electrical load control device caused by a short circuit across an electrical load.SOLUTION: A microcomputer 32 of a drive power distribution control device 31 detects a maximum current value of upper stage current (actual current flowing through a shunt resistor 41a of a power source side) measured for a predetermined period, and determines presence of overcurrent anomaly in the drive power distribution control device 31 when the maximum current value exceeds an abnormal current threshold value for a duration of anomaly detection time.

摘要： PROBLEM TO BE SOLVED: To provide a current limiting device capable of stably executing overload driving, with a simple configuration, without rasing a current output up to a use limit for current output blocking.
SOLUTION: An ECU sets a cooling time for cooling an output element heated under execution of overload driving, by decreasing an upper limit value Ilim of current limitation to a first value I1 corresponding to a rated current value from a second value I2 corresponding to the limit conduction value for a predetermined time Tx after execution of the overload driving. The ECU measures a continuation time t of overload driving. Based on the continuation time t, it calculates the time period for the cooling time, i.e., the predetermined time Tx.

摘要： PROBLEM TO BE SOLVED: To provide a solenoid control device capable of detecting an overcurrent and detecting short-circuit failure across a solenoid.SOLUTION: The solenoid control device executes feedback control so that a driving current of a solenoid 30 is an electric current that is a target current at every occasion by PWM-driving a MOSFET 41 provided in a feeding path of the solenoid 30. There is provided an overcurrent detection circuit 46 that outputs an overcurrent detection signal when the driving current of the solenoid 30 reaches an overcurrent determination current value. The presence/absence of an overcurrent is detected based on the overcurrent detection signal. By monitoring whether or not the overcurrent detection circuit 46 repeats an output and a stop of the overcurrent detection signal, the presence/absence of a short circuit across the solenoid 30 is detected .

摘要： PROBLEM TO BE SOLVED: To provide a driving force distribution control system with a good steering feeling that not only securely detects disconnection but also prevents torque shock or sound from being generated when checking the disconnection.SOLUTION: A microcomputer 30 makes test current flow for use to detect the disconnection failure of an inductive load circuit. It is counted that the disconnection failure has occurred in the inductive load circuit if a difference between the value of the test current and that of the current flowing in the inductive load circuit is greater than the current difference threshold value. Further, the disconnection failure is determined to stop the system operation if the count number counted as if the disconnection failure has occurred in the inductive load circuit exceeds a predetermined frequency when the test current flowing frequency reaches the predetermined one.
