摘要： An electrical storage system includes: an electrical storage device (10) including serially connected electrical storage blocks; a relay (SMR-B, SMR-G) switching a connection state between the electrical storage device and a load; a controller (30, 34) controlling the relay; and a current interruption circuit (60) interrupting energization of the electrical storage device. The current interruption circuit (60) includes an alarm circuit (63) outputting an alarm signal indicating that any one electrical storage block is overcharged or overdischarged by comparing a voltage value of each electrical storage block with a threshold; a latch circuit (64) retaining the alarm signal; and a transistor (68) causing the relay to switch from an on state to an off state upon reception of a latch circuit output signal. The controller determines an energization state of the electrical storage device after executing control for causing the alarm circuit to output the alarm signal by changing the voltage value or the threshold.

摘要： In requirement of catalyst degradation control with setting of a catalyst degradation control flag Fc to 1, the braking control of the invention sets torque commands Tm1* and Tm2* of two motors and controls the operations of an engine and the two motors to shift a drive point of the engine on an optimum fuel consumption operation curve by a preset rotation speed variation Nrt1 in a specific range of rotation speed that ensures no occurrence of a misfire in the engine within an input limit Win of a battery and to ensure output of a braking torque demand Tr* to a ring gear shaft or driveshaft (steps S200 to S250). Such braking control stably lowers a rotation speed Ne of the engine to a target rotation speed Ne* and desirably enhances the fuel consumption under the catalyst degradation control.

摘要： In a reverse drive with power output from an engine, the control procedure of the invention selects a drive point of the higher rotation speed corresponding to the higher accelerator opening among available drive points that ensure output of a target engine power, and controls the engine to be driven at the selected drive point and ensure output of a torque demand corresponding to the accelerator opening to a drive shaft. A required torque level output from a motor MG2 increases with an increase in engine torque under the conditions of a fixed torque demand of the drive shaft and a fixed output power level of the engine 22. Setting a drive point of the higher rotation speed and the lower torque corresponding to a higher level of the accelerator opening ensures output of the torque demand to the drive shaft. Setting a drive point of the lower rotation speed and the higher torque corresponding to a lower level of the accelerator opening improves the drive feeling of the engine.

摘要： A hybrid vehicle and a control method therefor detects malfunction of a fuel amount detector by accumulating a running distance (S110, S170), by detecting the amount of change of fuel amount (S120, S180), by estimating an amount of fuel for the accumulated the running distance (S130, 190) and by comparing the detected amount with the estimated amount. When the absolute value of the difference between the detected and estimated amounts is larger than a specified value ((Y1), S150, (Y2), S210), a malfunction of the fuel amount detector is determined (S160, S220). Depending on a selectable mode of the hybrid vehicle (hybrid mode, electric mode (S100)), different malfunction determinations with different specified values (Y1,Y2) are used.

摘要： An ECU (50) determines in an HV mode that a fuel sender gauge (41) is in malfunction when a first condition is met, and determines in an EV mode that the fuel sender gauge (41) is in malfunction when a second condition differing from the first condition is met. The first condition is met when the difference between an estimated value of the fuel consumption amount and an amount of change in the detection value by the fuel sender gauge (41) is greater than a predetermined value Z (S150). The second condition is met when the detection value changes exceeding a predetermined range X (S110).
