Patent ID: 8694220

Claim:
A vehicle left-right wheel drive force distribution control apparatus comprising: a steering speed detecting section that is configured to determine a steering speed; and a controller programmed to execute a distributed output of a wheel drive force to left and right drive wheels in accordance with a front-rear wheel drive force distribution control, the controller including a left-right drive force difference transient control computation value calculating section programmed to compute a left-right drive force difference transient control computation value as a basic target value for a transient control amount of a left-right drive force difference based on the steering speed, a left-right drive force difference transient control gain computing section programmed to compute a left-right drive force difference transient control gain based on the steering speed, and a left-right drive force computing section programmed to compute a target drive force for each of the left and right drive wheels based on a left-right drive force difference transient control amount obtained by multiplying the left-right drive force difference transient control computation value by the left-right drive force difference transient control gain; and the left-right drive force difference transient control gain computing section being further programmed to set the left-right drive force difference transient control gain to be lower while the steering speed is smaller than a first prescribed value as compared to while the steering speed is equal to or larger than the first prescribed value.
