摘要： A driveline system includes a drive axle coupled to a load, an electric machine, and a control system. The electric machine is responsive to a commanded torque, has a rotor shaft coupled to the axle, and produces an output torque that rotates the axle and load to produce driveline oscillation at a high resonant frequency. The control system generates the commanded torque using a nested control loop architecture in which an outer control loop operates at a sampling rate that is below a critical rate necessary for controlling the resonant frequency, and an inner control loop operates at a sampling rate that is above the critical rate. The inner loop determines a modified torque command and acceleration value in response to a commanded torque from the outer loop. The electric machine is thereafter controlled via the commanded torque.

摘要： An object of this invention is to obtain a vehicle control apparatus with which departure over a bump can be identified accurately, and when departure over the bump is identified, a required driving force can be controlled to an appropriate value. A departure over bump identification unit identifies departure over a bump, in which an electric vehicle travels over the bump in order to depart, when a motor rotation speed is equal to or lower than a predetermined first rotation speed and an accelerator pedal depression amount remains at or above a predetermined accelerator pedal depression amount continuously for a predetermined first period, and a drive control unit sets a required driving force of a motor at zero, regardless of the accelerator pedal depression amount, and then increases the required driving force at a constant speed, when departure over the bump is identified.

摘要： An object of the present invention is to provide a vehicle control apparatus and a vehicle control method capable of improving traceability when a speed reduction torque is applied. A vehicle control apparatus according to the present invention is configured to calculate the speed reduction torque to be generated on a vehicle based on an accelerator operation state and a front wheel slip angle. More specifically, when being brought into a turning state while a coasting torque is applied, the vehicle control apparatus makes a correction so as to reduce an absolute value of the coasting torque, thereby improving the traceability and the drivability.

摘要： A control apparatus and a control method that controls an electric oil pump that supplies oil to a power transmission device transmitting a drive force to an axle. The control apparatus changes a PWM frequency in a PWM control of the electric oil pump to a lower frequency, when a vehicle is in a pulled state, when a vehicle speed is high, when a power source is operated at a high rotational speed, when a discharge amount from the electric oil pump is large, or when a noise in a vehicle interior is large. Thus, a drive noise of the pump can be reduced, or the amount of heat generated in the pump drive circuit and power consumption can be reduced.
