摘要： PROBLEM TO BE SOLVED: To avoid generation of excessive torque in a power transmission mechanism transmitting power from a power source to wheels. SOLUTION: When sudden braking is performed while a vehicle 100 is travelling on a wavelike road, an ECU 150 controls brake oil pressure to be a threshold value or below. A brake actuator 120 controls oil pressure supplied to hydraulic brakes 30, 32, 50, 52 being controlled by the ECU 150. It is preferable that the ECU 150 controls the brake oil pressure to become higher than an effective value of the oil pressure in performing anti-lock brake control. Thus, generation of excessive torque in the power transmission mechanism (transmission members 15, 41, reduction gears 22, 42, axles 28, 48) transmitting power of a motor to the wheels can be avoided.

摘要翻译：要解决的问题：为了避免在从电源向车轮传递动力的动力传递机构中产生过大的转矩。解决方案：当车辆100在波浪路上行驶时进行突然制动时，ECU 150将制动油压力控制为阈值以下。制动致动器120控制供给由ECU 150控制的液压制动器30,32,50,52的油压。ECU 150优选地将制动油压控制为高于执行中的油压的有效值防抱死制动控制。因此，可以避免将电动机的动力传递到车轮的动力传递机构（传动构件15,41，减速齿轮22,42，轴28,48）中产生过大的扭矩。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a control unit of a hybrid vehicle capable of suppressing degradation of drivability occurring when a request driving force is augmented.SOLUTION: When an engine running mode is set to partial cylinder running (S1) and a power dividing mechanism is in a non-differential state (S2), if a request driving force is augmented, high-output mode switching control under which the engine running mode is switched from the partial cylinder running to all cylinders running, and differential state switching control under which the state of the power dividing mechanism is switched from the non-differential state to a differential state are implemented (S3). If an augmentation speed V of the request driving force exceeds a threshold Vth and a magnitude of augmentation Q exceeds a threshold Qth (S5 and S6), the high-output mode switching control and differential state switching control are concurrently implemented (S7). In the other cases, the high-output mode switching control is implemented. Thereafter, the differential state switching control is implemented (S8).

摘要： PROBLEM TO BE SOLVED: To attain both ensuring of vehicle performance and guaranteeing of durability of a pinion gear of a power dividing mechanism.SOLUTION: In a vehicle including a power dividing mechanism in a power transmission system, an engine operation range is determined with a limit value of the number of rotations of a pinion gear of the power dividing mechanism. Here, a limit value Pinlima (absolute value) of the number of rotations of the pinion gear on the side of a high engine rotational speed and low vehicle speed (zone Ra) is set to a value higher than a limit value Pinlimb (absolute value) of the number of rotations of the pinion gear on the side of a low engine rotational speed and high vehicle speed (zone Rb). Owing to this setting, while unnecessarily restricting the engine operation range on the side of the high engine rotational speed and low vehicle speed is avoided, excess rotation (overshoot) of the pinion gear on the side of the low engine rotational speed and high vehicle speed can be avoided.
