Abstract

A drive control device for an electric vehicle keeps the rotation speed of an engine unchanged before and after shifting, and does not bring unpleasantness, uncoordinated feeling, etc. to the driver. It has: a differential device, the first rotation element of which is connected with the first motor, the second rotation element is connected with the second motor via the transmission shaft (15), and the third rotation element is connected with the engine (11); the transmission (18), It speeds up the rotation transmitted by the transmission shaft (15); the compensation torque calculation processing unit calculates the inertia compensation torque along with the speed change of the speed changer (18), and the inertia compensation torque is used to compensate the inertia caused by the inertia and the target torque correction processing unit, which corrects the target torque of the first motor according to the inertia compensation torque. Accordingly, it is possible to prevent the rotational speed of the engine from changing due to inertia and control delay, and to prevent the inertia torque from being generated in the engine (11).

Description

technical field [0001] The invention relates to an electric vehicle drive control device and a control method thereof. Background technique [0002] Conventionally, a vehicle driving device is mounted on an electric vehicle, such as a hybrid vehicle, and transmits the torque of the engine, that is, a part of the engine torque to the generator, and the rest of the torque to the drive wheels. The drive device has a planetary gear assembly including a sun gear, an internal ring gear, and a planetary carrier. Furthermore, the above-mentioned carrier is connected to the engine, the ring gear and the electric motor are connected to the driving wheel through the transmission, the sun gear is connected to the generator, and the rotation output from the above-mentioned ring gear and the electric motor is transmitted to the driving wheel. and make it drive. [0003] However, when driving the engine to generate engine torque and transmitting it to the driving wheels through the above...
