Abstract:
1. A vehicle left-right wheel drive force distribution control apparatus comprising: 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 transient control computing section programmed to compute a left-right rear wheel drive force difference transient control amount in response to a driver requested transient turn response that is based on change rate of the steering angle and vehicle speed, the transient control computing section including a target yaw rate computing section that is programmed to a steady-state control computing section programmed to compute a left-right rear wheel drive force difference steady-state control amount by calculating the lateral acceleration rate and a longitudinal acceleration rate of the vehicle, a left-right rear wheel drive force difference computing section programmed to compute the sum of the left-right rear wheel drive force difference steady-state control amount and the left-right rear wheel drive force difference transient control amount, the sum being used as the target vehicle turning amount.
