Abstract: The present invention relates to a method (4) for controlling the power train of a vehicle (1), the power train being installed in the vehicle by means of suspensions (18) and comprising an electric motor (10) able to transmit a torque to the wheels (16) of the vehicle. The motor comprises a blocking finger (101) able to switch from an engaged configuration in which the rotor (102) of the motor is rigidly attached to the stator of the motor in order to ensure immobilisation of the vehicle, to a disengaged configuration where the rotor (102) is released from the stator in order to allow driving of the vehicle. The method includes a dynamic correction step of the speed of the motor, such that, on switching from the engaged configuration to the disengaged configuration of the locking finger when the vehicle is immobilised on a slope, the oscillations of the power train on the suspensions around the axles of the wheels are damped. Application: motor vehicle.

Abstract: The objective of the present invention is to prevent misjudgment of the start of fastening of a friction fastening element when a drive source undergoes rotational fluctuation due to a disturbance factor other than the start of fastening of the friction fastening element. A device for controlling a hybrid vehicle is provided with: a drive source including at least an engine (Eng) and a motor/generator (MG); a second brake (B2) that is fastened when a D range is selected; a control means (step S3 in fig. 6 ) that, by means of controlling the rotational frequency of the motor/generator (MG, maintains the input rotational frequency of the second brake (B2) at the start of fastening control; and a fastening start judgment means that judges that the second brake (B2) has started fastening when, in a range for starting second brake (B2) fastening control, a parameter that changes alongside the engine (Eng) undergoing rotational fluctuation becomes at least a predetermined threshold. The judgment is started (step S6, S9) after waiting from the start of second brake (B2) fastening control until a predetermined time at which it can be determined that the rotational fluctuations of the motor/generator (MG) and the engine (Eng) due to a disturbance factor other than the start of fastening of the second brake (B2) have converged.

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: 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 Dωg, 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 Dωg is greater than a criterion value Dωgth.

Abstract: A slip control device for an electric vehicle which accurately determines slippage occurrence with only a rotation angle sensor for motor rotation control and perform rapid control to eliminate the slippage, is provided. A threshold calculation module (21) calculates a normal angular acceleration of a motor depending on a manipulation amount of an accelerator to obtain a threshold, and an angular acceleration calculator (22) differentiates a detection value from a rotation angle sensor (3a) twice to calculate an angular acceleration. A slip determination (23) determines whether a drive wheel (7) has slipped, and a torque limitation (25) limits a torque when a slippage has occurred. The determination (23) determines the angular acceleration and a threshold. The determination (23) counts a number of consecutive times it is determined that the threshold is exceeded, and determines that a slippage has occurred, if the number of consecutive times has reached a set value. The limitation (25) limits a torque developed by a motor unit for a drive wheel laterally opposite to the drive wheel determined as having slipped.
