Braking/driving force controller of vehicle
First Claim
1. A vehicle braking/driving force control apparatus comprising:
- braking/driving force applying means that applies braking/driving forces to wheels;
means for detecting an amount of driving operation by an occupant;
means for calculating a vehicle target braking/driving force and a vehicle target yaw moment, based on at least the amount of driving operation by the occupant; and
control means for controlling the braking/driving force applied to each wheel by said braking/driving force applying means such that, when at least one of said vehicle target braking/driving force and said vehicle target yaw moment is not within an achievable range by the braking/driving forces of the wheels, a vehicle braking/driving force and a vehicle yaw moment are set to maximum values, respectively, within the achievable range, where a ratio of the maximum value of the vehicle braking/driving force and the maximum value of the vehicle yaw moment substantially coincides with a ratio of said vehicle target braking/driving force and said vehicle target yaw moment.

Abstract
In a braking/driving force control apparatus, a vehicle target braking/driving force and a vehicle target yaw moment through the control of braking/driving forces of wheels are calculated, and when the target braking/driving force and the target yaw moment cannot be achieved through the control of the braking/driving forces of the wheels, the vehicle target braking/driving force after the modification and the vehicle target yaw moment after the modification are calculated such that, within the range where the ratio of the vehicle target braking/driving force after the modification and the vehicle target yaw moment after the modification coincides with the ratio of the target braking/driving force and the target yaw moment, the vehicle braking/driving force and the vehicle yaw moment by the target braking/driving forces of the wheels take the greatest values.
