Vehicle braking/driving force control system and vehicle braking/driving force control method

摘要

Braking/driving force control that includes: detecting a driver's operating state for causing the vehicle to run; detecting a vehicle body motional state while the vehicle is running; computing a target longitudinal driving force for causing the vehicle to run and motional state amounts for controlling a vehicle body behavior on the basis of the detected operating state and motional state; and computing driving or braking forces allocated to the wheels so as to achieve the computed target longitudinal driving force and target motional state amounts and that the braking/driving force generating mechanism causes the wheels to generate independently.

1. A vehicle braking/driving force control system comprising:
a braking/driving force generating mechanism that causes each wheel of a vehicle to generate driving force or braking force independently of one another; a suspension mechanism that couples each of the wheels that are not supported by springs of the vehicle to a vehicle body that is supported by the springs of the vehicle; an operating state detecting unit configured to detect a driver's operating state for causing the vehicle to run; a motional state detecting unit configured to detect a motional state of the vehicle body while the vehicle is running; a vehicle body behavior control value computing unit configured to compute a target longitudinal driving force for causing the vehicle to run on the basis of a detected driver's operating state, and a plurality of target motional state amounts for controlling behaviors of the vehicle body which are a target roll moment, a target pitch moment, and a target yaw moment on the basis of the detected driver's operating state and a detected motional state; and a driving force allocation computing unit configured to compute driving forces or braking forces respectively allocated to the wheels so as to achieve a computed target longitudinal driving force and a plurality of computed target motional state amounts which are the target roll moment, the target pitch moment, and the target yaw moment at the same time and that the braking/driving force generating mechanism causes the wheels to respectively generate independently of one another.
