摘要： A drive apparatus basically comprises left and right drive units each including at least a reduction gear, an electric motor without a permanent magnet, and a brake disc. Each of the left and right drive units is housed substantially within a rim of each of rear wheels which are driven wheels. A 4WD control unit is configured to control a pair of inverters to separately drive the electric motors when a vehicle speed is in a range between a standing start speed and a prescribed vehicle speed, and to stop driving the electric motors when the vehicle speed is equal to or greater than the prescribed vehicle speed to place the rear wheels in a driven state. Accordingly, a friction loss due to a cogging torque encountered in a conventional permanent magnet-type motor is eliminated, and a lightweight drive apparatus is obtained. Fuel efficiently is accordingly improved.

摘要： A malfunction detection circuit that detects a cell malfunction alternately outputs the results of an overcharge detection executed during an overcharge detection period and the results of an over-discharge detection executed during an over-discharge detection period through time sharing based upon a clock signal. When the cell is in the normal range, the signal level of the signal output during the overcharge detection period is different from the signal level of the signal output during the over-discharge detection period. Thus, in the malfunction detection, the signal generated when an overcharge malfunction has occurred in the cell can be distinguished from the signal generated when an over-discharge malfunction has occurred in the cell.
摘要翻译：检测电池故障的故障检测电路交替地输出基于时钟信号通过时间共享在过充电检测期间执行的过充电检测结果和在过放电检测期间执行的过放电检测结果。当单元处于正常范围时，过充电检测期间输出的信号的信号电平与过放电检测期间输出的信号的信号电平不同。因此，在故障检测中，当在单元中发生过充电故障时产生的信号可以与在单元中发生过放电故障时产生的信号区分开。
