VEHICLE CONTROL DEVICE, VEHICLE CONTROL METHOD, AND VEHICLE CONTROL SYSTEM
An electrically controlled differential gear is disposed between a right front wheel and a left front wheel of a vehicle. The electrically controlled differential gear includes a clutch mechanism that limits a differential operation of the electrically controlled differential gear. A second ECU (control portion) obtains information as to failure associated with actuation of a right front electric brake mechanism. The second ECU obtains a physical amount relating to a required braking force which is applied to the left front wheel and the right front wheel. The second ECU outputs a differential limiting control command for limiting the differential operation of the electrically controlled differential gear to the clutch mechanism (or more specifically, a differential ECU that controls the clutch mechanism) based on the information as to the failure and the physical amount relating to the required braking force.
METHOD FOR CONTROLLING A MOTOR VEHICLE IN EMERGENCY STEERING MODE BY MEANS OF FRONT WHEEL BRAKE-BASED TORQUE VECTORING
A method can be used to control a steer-by-wire steering system in an emergency steering mode. The method comprises checking a steering system for the presence of a fault state and upon detection of a fault implementing the emergency steering mode, which involves determining a setpoint position of a steering tie rod using a setpoint wheel steering angle, determining a front wheel to be braked and a brake pressure to attain the setpoint position with a control unit, transmitting the front wheel to be braked and the brake pressure to a brake system, braking the front wheel to be braked, and increasing a torque provided by a wheel drive to compensate for a loss of speed of the motor vehicle caused by the braking of the front wheel to be braked.
BRAKING CONTROL DEVICE
A control device includes: a first braking unit, that applies a first braking force to a steering wheel of a vehicle; a second braking unit, that applies a second braking force to a non-steering wheel of the vehicle; and a control device that controls the first braking unit, and the second braking unit, according to a target braking force, where the control device includes a steering angle information acquiring unit that acquires a steering angle-related value related to a steering angle of the steering wheel, and a distribution changing unit that executes a distribution change control of changing a braking force distribution between the first braking force and the second braking force based on the steering angle-related value when the target braking force is applied.
Vehicle antilock brake system control device
A wheeled vehicle's antilock brake system (ABS) control device has three kinds of control modes of a braking force oriented mode, a sideways force oriented swinging-motion suppression mode and a sideways force oriented swinging-motion enhancement mode each of which is an ABS control mode being selected by means of an ABS control mode selection unit; and the vehicle ABS control device is so arranged that, in accordance with an ABS control mode selected by the ABS control mode selection unit, target slip rates on each of the vehicle's wheels being set by a target slip-rate setting unit are transferred toward respective braking force orientation or sideways force orientation, thereby the behavior of a wheeled vehicle is stabilized at a time when the wheeled vehicle on which the vehicle ABS control device is mounted makes a turn.
VEHICLE MOTION CONTROL APPRATUS
In a vehicle, GV control and M+ control are executed by generating braking/driving forces from a brake hydraulic pressure control device and a drive device during steering. A controller estimates (calculates), by a posture estimation unit, a pitch amount and a roll amount (predicted pitch rate and predicted roll rate) that occur in the vehicle through use of a moment command of the M+ control and a longitudinal G command of the GV control. The controller adjusts damping forces of damping force variable dampers through use of the estimated pitch amount and the estimated roll amount (predicted pitch rate and predicted roll rate) so that a pitch amount calculated by a pitch control unit and a roll amount calculated by a roll suppression unit approach respective target values.
METHOD FOR CONTROLLING A MOTOR VEHICLE
A method automatically controls an actuator of a control system of an automotive device. The method includes determining a reference trajectory, determining a position of the device with respect to the reference trajectory, acquiring a parameter relating to a force exerted by a driver on a manual control device of the control system, and calculating a controlling setpoint of the actuator. The controlling setpoint is calculated as a function of the parameter and of the position of the device with respect to the reference trajectory.

Vehicle braking force control device
The present invention prevents occurrence of abnormal noise and swing of a vehicle in mitigating braking force of a steered wheel while reducing a steering load at the time of stationary steering to reduce a burden of a steering device and reducing stress accumulation due to stationary steering to reduce burdens of a tire, a suspension device and the steering device.
