Abstract: An unsprung state detection part (140) calculates a variation amount X (=|(ϕ-ϕ'|), which is a magnitude of a difference between a detected angle ϕ output from a resolver rotational angle sensor (40) for detecting a rotational angle of an in-wheel motor (30) and an estimated angle ϕ' of a motor rotational angle (S11 to S13). The estimated angle ϕ' can be calculated by adding an estimated angle of the rotation of the motor (30) in one calculation cycle to a detected angle ϕn-1 of the previous calculation cycle. When the variation amount X is more than a road surface determination threshold Xref, the unsprung state detection part (140) determines that the travel road on which a vehicle (1) is traveling is a rough road (S14, S15). As a result, the road surface determination can be made by using the rotational angle sensor (40).

Abstract: In a hybrid vehicle in which a fixed speed change mode can be realized by the locking of a rotational element, the mislocking of the rotational element is prevented. A hybrid drive apparatus 10 which has an engine 200, a MG1 and a MG2 and which functions as a power unit of a hybrid vehicle 1 is provided with a brake mechanism 700 of a cam-lock type which can control the MG1 in a lock state and a non-lock state by changing the state of a sun gear S1 between the lock state and the non-lock state. In mislocking prevention control, an ECU 100 calculates MG1 angular acceleration DÉg, which is the absolute value of angular acceleration of the motor generator MG1, on the basis of a MG1 rotational speed Ngm1 and judges that the sun gear S1 is in a mislocking state if the MG1 angular acceleration DÉg is greater than a criterion value DÉgth.

Abstract: The present invention is directed to solve the problem of generation of overdischarging from a power storage device according to compensation for reduction in electrical power generated by an MG1 corresponding to reduction in the revolution speed of the MG1. When detection is made of reduction in the revolution speed of the MG1 corresponding to reduction in the engine speed, any of the four following operations is carried out: (1) modifying the output torque of the MG1 such that electrical power generated by the MG1 increases; (2) modifying the output torque of an MG2 such that power consumption by the MG2 is reduced; (3) forcing the control mode of the MG1 to be changed to PWM control from one-pulse switching control; and (4) reducing the DC voltage command value for the converter.

Abstract translation: 本发明旨在解决由与MG1的转速降低对应的由MG1产生的电力的减少的补偿，从蓄电装置产生过放电的问题。 当检测到对应于发动机转速降低的MG1的转速的降低时，进行以下四个以下操作中的任何一个：（1）修改MG1的输出转矩，使得MG1产生的电力增加 ; （2）修改MG2的输出转矩，使得MG2的功耗降低; （3）强制将MG1的控制模式从单脉冲切换控制改变为PWM控制; 和（4）降低转换器的直流电压指令值。

Abstract: The invention relates to a method for determining the beginning of a start phase of an internal combustion engine in a hybrid vehicle, wherein a second drive unit (1) drives the hybrid vehicle, wherein the internal combustion engine (3) is started when the second drive unit (1) has reached a certain drive torque (M
trqMax ). In order to always achieve the maximum purely electric driving range of the hybrid vehicle with the second drive unit, and at the same time improve the driving comfort of the hybrid vehicle by optimizing the internal combustion engine start triggering, the internal combustion engine (3) is started when a predicted drive torque (M
trqMaxPrdc ) of the second drive unit (1) is smaller than or equal to the currently measured (M
trq ) drive torque of the second drive unit that is increased by a torque reserve (M
Start ).

Abstract: A hybrid vehicle has an engine (11), a generator motor (16), an output shaft (14) connected to a drive wheel (37), a differential gear device (13), fixing means for mechanically fixing a rotation of the generator motor (16), correction value calculation processing means (91) for calculating a correction value based on an estimated engine torque calculated through estimation and a generator motor torque, and engine torque correction processing means (92) for correcting the estimated engine torque by the correction value. The correction value is calculated based on the estimated engine torque calculated through estimation and the generator motor torque, and the estimated engine torque is corrected by the correction value. Therefore, it is possible to prevent an event that after the fixation of rotation by the fixing means is removed, the rotor of the generator motor is affected by the service condition of the engine.
