Title:
BRAKE DRIVE FORCE CONTROL DEVICE, VEHICLE CONTROL DEVICE, VEHICLE CONTROL METHOD AND VEHICLE CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2019189063
Kind Code:
A
Abstract:
To provide a brake drive force control device which can stably control a brake drive force.SOLUTION: A target brake drive force output from a vehicle control controller 10 and a target slip rate are inputted to a brake drive force controller 20, and also a wheel speed signal is inputted thereto from a wheel speed sensor 3 for detecting a physical amount related to a wheel speed of a vehicle. The brake drive force controller acquires a slip-time brake drive force for obtaining a target slip rate corresponding to a slip rate of wheels on the basis of a magnitude relationship between the inputted wheel speed signal and the information on the target slip rate. A brake drive force control signal based on the slip-time brake drive force and the target brake drive force is output to an actuator 30 related to the brake drive of the vehicle. Then, control by the target brake drive force is performed up until the brake drive force controller detects the lock or slip of the wheels, and when the lock or slip of the wheels is detected, the brake drive force controller switches control to control by the slip-time brake drive force corresponding to the slip rate.SELECTED DRAWING: Figure 2
