摘要： PROBLEM TO BE SOLVED: To avoid the deterioration of the traveling performance of a vehicle caused by the lowering of an engine output caused by power generation for motor four-wheel driving. SOLUTION: A motor torque command value dTm rises at a time t1 when an amount of a front-wheel drive slip reaches a value not smaller than a four-wheel drive start determination value, thus bringing about a four-wheel drive state that rear wheels are driven, too. Since a large target drive force cannot be set because a road-face friction coefficient is so extremely small as a frozen road or the like has until a time t2 comes when the target drive force reaches a target drive force setting value, the maximum value dTmmax of a motor torque command is made to be a motor torque maximum value Tmmax that is necessary for the elimination of the front-wheel drive slip. After the time t2, a large drive-force drive state that the large target drive force can be set because the road-face friction coefficient is so comparatively large as a snow-compacted road has, the dTmmax is lowered to Tmmax×0.5. By this, an amount of engine power consumed for the driving of a generator can be reduced, thus avoiding the deterioration of the traveling performance. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：为了避免由于电机四轮驱动的发电引起的发动机输出的降低而导致的车辆行驶性能的劣化。解决方案：当前轮驱动滑移量达到不小于四轮驱动开始判定值的值时，电动机转矩指令值dTm在时刻t1上升，从而产生四轮驱动状态后轮也被驱动。由于当目标驱动力达到目标驱动力设定值时，由于路面摩擦系数如冻结路面等直到时间t2到达为止，所以无法设定大的目标驱动力，所以最大值dTmmax 使电动机转矩指令成为消除前轮驱动滑差所需的电动机转矩最大值Tmmax。在时间t2之后，由于道路面摩擦系数相对较大，因为积雪道路，dTmmax降低到Tmmax×0.5，所以能够设定大的目标驱动力的大的驱动力驱动状态。由此，可以减少用于发电机的驱动的发动机功率的量，从而避免行驶性能的劣化。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To drive an inverter simultaneously with switching operation between a PWM controlling operation and a rectangular-wave controlling operation, while suppressing heating in the inverter. SOLUTION: A temperature monitoring means 37 monitors temperature in the inverter 19, and a maximal driving-time acquiring means 38 acquires the maximal driving time of the inverter 19 under a PWM controlling operation, based on an initial temperature and a torque command value on initiating the inverter 19. A heating determination means 35 determines that a heating value Hi in the inverter 19 exceeds a predetermined value Hi when a real driving time of the inverter 19 runs over the maximal driving time, and directs a second switching means 34 to change a controlling mode from the PWM controlling operation to the rectangular-wave controlling operation. The second switching means 34 directs a PWM controlling means 32 to stop the PWM controlling operation, and at the same time directs a rectangular-wave controlling means 31 to set the inverter 19 under the rectangular-wave controlling operation.

At S24, motor torque Tm is searched from the conduction amount of a motor, field voltage of the motor and the motor temperature based on a predetermined map, and the motor torque is feedback controlled such that a motor torque estimation value Tm increases while following up a motor torque command value having a time series variation determined not to exceed an allowable upper limit value of motor torque corresponding to the allowable maximum torque of a reduction gear provided between the motor and the motor drive wheel (rear wheel).

摘要： PROBLEM TO BE SOLVED: To propose hill start control for early eliminating the roll back of an electric motor type four-wheel-drive-vehicle in hill start. SOLUTION: In hill start performed by releasing a brake pedal at t1, and pressing on a gas pedal at t2, the delay control of the increase in an engine output is performed so that the increase in the driving force of front wheels being engine driven wheels can be delayed against the pressing-on of the gas pedal as shown by Tf in the roll back when a speed VSP is generated in a backward direction. When the front wheel driving force (engine torque) is tried to increase as a dashed line Tfo according to the pressing-on of the gas pedal, the front wheel driving force is decreased as shown by a real line Tfo due to the driving slip of the front wheels, and the roll back is not eliminated until t4. The delay control of the engine output increase is performed to prevent the driving slip of the front wheels so that the front wheel driving force can be maintained so as to be large as shown by Tf, and that the roll back can be eliminated earlier at t3.

解决方案：在t1起动时，通过释放制动踏板，在t2时按下加速踏板，进行起动启动，执行发动机输出增加的延迟控制，使前轮驱动力的增加为如果沿向后方向产生速度VSP，发动机驱动的轮子可以抵抗加速踏板的按压而被延迟，如Tf所示。当根据油门踏板的按压试图增加前轮驱动力（发动机扭矩）作为虚线Tfo时，如实线Tfo所示，前轮驱动力由于驾驶滑动而减小前轮和后轮不会消除，直到t4。执行发动机输出增加的延迟控制以防止前轮的驾驶滑动，使得如Tf所示可以将前轮驱动力保持为大，并且可以在t3更早地消除回滚。版权所有（C）2007，JPO＆INPIT
