Embodiment Construction

[0042] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. At this time, a hybrid vehicle as an electric vehicle will be described.

[0043] figure 1 It is a functional block diagram of the electric vehicle drive control device according to the embodiment of the present invention.

[0044] In the figure, 91 is a condition judging processing mechanism that reads a vibration judging index that is a key factor that generates vibration in a vehicle driving device, and judges whether the vibration damping control start condition is established based on the vibration judging index, and 92 is a condition judging mechanism when the above vibration damping control is established. A vibration-damping control processing mechanism that performs vibration-damping control processing to reduce vibration generation variables when a start condition is met.

[0045] Next, the compound vehicle will be described.

[0046] ...

Abstract

The invention relates to a driving controller of electric vehicle and a relative driving control method, wherein said device has the vibration judgment index on the key factor that generates the vibration of driver, and a condition judgment processor (91) that based on said index judges if the damping control should be started, and a damping control processor (92) for reducing the vibration variable via damping control; therefore, it can control the damping to reduce the vibration variable when the damping control start condition is met, the vibration of driver can be damped.

Description

technical field [0001] The invention relates to an electric vehicle drive control device and an electric vehicle drive control method. Background technique [0002] In the past, a vehicle drive device mounted on a compound vehicle as an electric vehicle, which transmits part of the engine torque, which is the engine torque, to the generator (generator motor) and the rest to the driving wheels has a sun The planetary gear unit as a differential device, the ring gear and the planetary carrier, the above-mentioned sun gear is connected to the generator, the ring gear and the driving motor are connected to the driving wheel, the planetary carrier is connected to the engine, and the output from the above-mentioned ring gear and driving motor The rotation is transmitted to the drive wheels, thereby generating drive force. [0003] In the above-mentioned vehicle driving device, an inverter is provided between the driving motor and the driving motor control device. The inverter is ...
