Problems solved by technology

However, due to the difference between the left and right driving force adjustment level and the differential limiting level at the time of switching between the left and right driving force adjusting means and the differential limiting means, there may be a sudden change in the driving force difference to make the vehicle behave differently. continuous

Abstract

A controller includes: a adjuster, configured to adjust distribution of driving force between right and left wheels; a limiter, configured to limit a difference between operations of the right and left wheels; a first calculator, configured to calculate a first control amount corresponding to the adjustor and including an amount related to direction of shift of driving force between the right andleft wheels; a second calculator, configured to calculate a second control amount corresponding to the limiter; a third calculator, configured to calculate a third control amount including the secondcontrol amount and the amount; a fourth calculator, configured to calculate a fourth control amount that is a combination of the first and third control amounts; a selector, configured to select either the adjustor and the limiter; and a controller, configured to control the adjustor or the limiter in accordance with the fourth control amount.

Description

technical field [0001] The present invention relates to left and right driving force controllers, and more particularly, to a technique for controlling left and right driving forces maintaining stable vehicle behavior. Background technique [0002] A left and right driving force distributor has been developed which controls a yaw moment acting on a vehicle by generating a difference in driving force of a left wheel and a driving force of a right wheel during turning of the vehicle. The steering characteristics of the vehicle are thereby improved. [0003] However, the left and right driving force divider of the related art generates a difference between the left and right wheels depending on the driving force, and faces a problem of not being able to prevent slipping in the left and right wheels during straight forward running of the vehicle, and the like. [0004] JP-A-2007-145305 describes a left and right driving force distributor having left and right driving force adju...
