HYBRID POWER SYSTEM FOR USE IN VEHICLE AND CONTROL METHOD THEREOF
A hybrid power system comprises an engine, a hybrid power module, and a dual input shaft speed change mechanism. The hybrid power module comprises a motor, a planetary gear system, and a first clutch. The planetary gear system is provided with at least three rotating shafts, which respectively are: a rotating shaft X1, a rotating shaft X2, and a rotating shaft X3. The first clutch is arranged between any two of the three rotating shafts. A power output shaft of the engine is connected to the rotating shaft X3 or the rotating shaft X1 and to a second input shaft of the dual input shaft speed change mechanism. A rotor of the motor is connected to the rotating shaft X1 or to the rotating shaft X3. The rotating shaft X2 is connected to a first input shaft of the dual input shaft speed change mechanism.
Drive control apparatus for drive system of vehicle
A drive control apparatus is applied to a drive system that is mounted to a vehicle, drives wheels of the vehicle by a motor, and brakes the wheels by a brake apparatus. The drive control apparatus determines a road-surface state of a travel road of the vehicle. The drive control apparatus suppresses slipping of the vehicle by correcting a drive torque by correcting at least either of a motor torque and a brake torque. When determined that the drive torque is to be corrected, the drive control apparatus adjusts a correction amount of the drive torque by adjusting the motor torque with higher priority than the brake torque in response to be determined that the road-surface state is rough.

Load driving device
A load driving device includes a synchronous rectifier circuit having a driving-side switching element and a reflux-side switching element; a driver control circuit controls the synchronous rectifier circuit; and a voltage monitor circuit that monitors whether the voltage of an output terminal of the synchronous rectifier circuit is within a predetermined voltage range; where the driver control circuit, upon receiving a diagnosis command, performs control so that when the driving-side switching element is switched from ON to OFF, the reflux-Side switching element is also switched to OFF; and the voltage monitor circuit detects a normal state when the voltage to be monitored is within a normal level during a period in which both the driving-side switching element and the reflux-side switching element are turned OFF.
Vehicle vibration control device
A vehicle vibration control device includes: a motor generator connected via a motor shaft to a power transmission path between a crankshaft of an engine and a drive axle that transmits a drive torque to a tire; and a motor generator control portion executing control of an output torque which is actually output by the motor generator.

Controller and control method for vehicle
A controller for a vehicle is configured to execute, when a state of charge of a battery is less than or equal to a threshold, a charging control to charge the battery with power that is generated by a motor generator using driving force of an internal combustion engine. The controller is also configured to obtain a temperature of the battery, set the threshold to a first threshold during a warm-up period, which is a period from a start of the internal combustion engine until the warm-up of the internal combustion engine is completed, set the threshold to a second threshold, which is greater than the first threshold, when the warm-up period ends, and set the second threshold to be greater when the temperature of the battery is a first temperature than when the temperature of the battery is a second temperature, which is higher than the first temperature.
