VEHICLE STEERING CONTROL APPARATUS

A vehicle steering control apparatus includes a target course setter, a first control quantity calculator, a second control quantity calculator, a control rate variator, and a steering controller. The target course setter sets, based on forward environment information, a target course to be traveled by an own vehicle. The first control quantity calculator calculates a first control quantity that allows the own vehicle to travel along the target course. The second control quantity calculator calculates a second control quantity based on a steering angle. The control rate variator variably sets, in accordance with a vehicle speed, a first rate of the first control quantity and a second rate of the second control quantity. The steering controller calculates a steering control quantity, based on the first control quantity corrected based on the first rate and the second control quantity corrected based on the second rate, and executes a steering control.
