Title:
VEHICLE CONTROL APPARATUS, VEHICLE CONTROL METHOD, AND VEHICLE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/058940
Kind Code:
A1
Abstract:
Provided are a vehicle control apparatus, vehicle control method, and vehicle control system capable of optimizing the balance between a target tire lateral force and a target tire fore-aft force. The vehicle control apparatus outputs, to an actuator for the braking and driving of the vehicle, a command for achieving the optimal slip ratio corresponding to the minimum value of the sum of a first difference and a second difference, the first difference being the difference between the tire lateral force and the target tire lateral force with respect to a given slip ratio from the correlation between the slip ratio of the tire of a wheel unit and the tire lateral force, the second difference being the difference between the tire fore-aft force and the target tire fore-aft force with respect to the given slip ratio from the correlation between the slip ratio and the tire fore-aft force.
