Vehicle steering control apparatus
First Claim
1. A vehicle steering control apparatus, comprising:
- a target course setter that sets, based on forward environment information, a target course to be traveled by an own vehicle;
a first control quantity calculator that calculates a first control quantity based on a target steering angle to allow the own vehicle to travel along the target course, the target steering angle being calculated based on the forward environment information;
a second control quantity calculator that calculates a second control quantity, the second control quantity being based on a detected steering angle detected by a sensor of the own vehicle;
a control rate variator that variably sets, in accordance with a vehicle speed, a first rate of the first control quantity in a steering control quality and a second rate of the second control quantity in the steering control quality; and
a steering controller that calculates the steering control quantity, based on a first corrected control quantity that is set by correcting the first control quantity based on the first rate and a second corrected control quantity that is set by correcting the second control quantity based on the second rate, and executes a steering control of the own vehicle based on the steering control quantity.

Abstract
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.
