摘要： In response to a decrease in observed battery voltage Vb to or below a preset threshold value Vs1, the control procedure of the invention closes the gates of an inverter for an air conditioner to stop a supply of electric power to the air conditioner (at a time point t1). In response to a further decrease in observed battery voltage Vb to or below a preset threshold value Vm1, the control procedure closes the gates of inverters for motors MG1 and MG2 to stop supplies of electric power to the motors MG1 and MG2 (at a time point t2). The threshold values Vs1 and Vm1 are set to keep the battery voltage Vb at or above a minimum required voltage for proper operations of an electric power steering (EPS). This arrangement guarantees the minimum required voltage for proper operations of the EPS and accordingly ensures the stable steering performance even in the event of a voltage decrease of the battery.

摘要： An ECU determines whether or not there is an abnormality (shift pattern abnormality) in a combination of shift signals provided from a shift position sensor. After occurrence of the shift pattern abnormality is determined, the ECU determines whether or not a first condition that a shift pattern changes into a normal pattern of a drive range is satisfied, and whether or not a second condition that a vehicle is running (a driver has an intention to cause the vehicle to run) is satisfied. When occurrence of the shift pattern abnormality is determined, the ECU stops generation of driving force of the vehicle and prohibits switching to the drive range. When the above-mentioned first condition and second condition are satisfied after occurrence of the shift pattern abnormality is determined, the ECU switches the shift range to the drive range indicated by the shift pattern and recovers the driving force.

摘要： During the deactivation of a driving system of a vehicle, an ECU determines whether or not a P range abnormality occurs which exhibits that a shift signal transmitted from a shift position sensor includes a P signal and an MJ signal corresponding to the P range as well as a different-type signal other than the P signal and the MJ signal. When the P range abnormality occurs, the ECU determines whether or not the vehicle-stopped state can be assured based on whether or not a brake-ON state (a hydraulic braking force or a parking braking force are beyond the range capable of maintaining vehicle-stopped state) is present. In a case where a P range abnormality occurs, when ECU determines that the vehicle-stopped state can be assured, the ECU allows the activation of the driving system.

摘要： A device and method for determining whether a malfunction is present in a drive circuit, which drives an electric device that generates counter-electromotive force, when all gates in the switching elements of the drive circuit are blocked. After the gates are blocked, the temperature of the switching elements is monitored and the presence of a malfunction is determined based on the detected temperature of the switching elements. A malfunction is determined to be present when the detected temperature equals or exceeds a predetermined temperature; the change in the detected temperature equals or exceeds a predetermined value; or the rate of change in the detected temperature equals or exceeds than a predetermined rate. Thus, it can be appropriately determined whether the gates in the drive circuit are appropriately blocked and minimize the influence of any malfunctions on other elements outside of the drive circuit.

摘要： Upon receiving a start instruction, a control device turns on first and third system main relays, and performs precharge processing for charging a capacitor. Here, a limiting resistor for preventing an inrush current into the capacitor in a discharged state at the time of start is not provided in a load drive device. The control device controls a gate voltage of a power MOSFET of the third system main relay such that the power MOSFET operates in a saturation region, in a range not exceeding a maximum rated power.
