Systems for distributing braking force and related methods
A system includes a controller configured to individually control brake force applied to steered wheels of a vehicle. The controller is configured to release a braking force from a first brake associated with a first steered wheel of the vehicle when the vehicle is stationary, and the controller is further configured to subsequently release a braking force from a second brake of a second steered wheel when the vehicle remains stationary after braking force is released from the first wheel. Methods relate to distributing braking force of a vehicle.
STEERING FAILURE BRAKE SYSTEM REACTION
When a vehicle experiences an instability event, an instability event trigger (e.g., a failed modulator, unexpected yaw or lateral acceleration, unexpected steering wheel position change, etc.) is monitored and the magnitude thereof is compared to a corresponding predetermined threshold above which corrective action is initiated. Depending on the magnitude and type of instability trigger, one or more wheel ends are identified as candidates for brake activation. Braking force at the identified wheel ends is gradually increased until the vehicle becomes stable or comes to a stop.
Method for controlling a vehicle
A method of controlling a vehicle including providing a system having a plurality of brakes and a curve detecting mechanism. Each brake of the plurality of brakes is configured to slow rotation of a respective wheel. The method further includes detecting a curve in a forward travel path of the vehicle using the curve detecting mechanism. At least two brakes but fewer than all of the plurality of brakes are pre-filled in response to the detection of a curve.
Vehicle control apparatus
A vehicle control apparatus includes a contact detector, an attitude stabilization processor, and a steering intention determining unit. The contact detector is configured to detect a contact of a vehicle with an object. The attitude stabilization processor is configured to execute an attitude stabilization control that generates a yaw moment at a vehicle body on the basis of a deviation between a target yaw rate and an actual yaw rate. The steering intention determining unit is configured to determine a presence of a driver's intention to perform steering. The attitude stabilization processor is configured to stop the generation of the yaw moment by the attitude stabilization control or reduce the yaw moment to be generated by the attitude stabilization control, in a case where the steering intention determining unit determines that the driver's intention to perform the steering is absent after the detection of the contact by the contact detector.
VEHICLE STABILITY CONTROL SYSTEM AND METHOD
A vehicle stability control system and a vehicle stability control method which are capable of more improving lateral stability of a vehicle when the vehicle is turning on a descent inclined road, may enable the vehicle to turn along a turning trace intended by a driver through cooperative control of active front steering (AFS) control and an electronic stability control (ESC) when the vehicle is turning on the descent inclined road.
Suspension architecture for steer-by-wire vehicle
A vehicle has a wheel, a frame, a suspension component, a steering knuckle, and a steering system. The suspension component is connected to the frame. The steering knuckle is connected to the suspension component and is connected to the wheel. The suspension component is operable to control vertical movement of the steering knuckle and the wheel relative to the frame. The suspension component and the steering knuckle define a steering axis for the wheel. The steering axis has a caster inclination angle of zero degrees. The steering system is connected to the suspension component and controls a steering angle of the wheel based on an electronic control signal.
Brake system for vehicle
A brake system for a vehicle, may include a brake input device to apply a brake input of a driver; a brake actuator generating braking hydraulic pressure; wheel cylinders generating braking force for each vehicle wheel by the braking hydraulic pressure generated by the brake actuator; and a hydraulic pressure supply line connecting the brake actuator and the wheel cylinders, wherein the brake actuator includes a main pump device by which braking force is applied, and a sub control device configured for adjusting the braking force applied by the main pump device.
VEHICLE BEHAVIOR CONTROL DEVICE
The vehicle behavior control device comprised a drive control system 4 and a brake control system 18, wherein a PCM 14 is configured, when steering angle is increasing, to set an additional deceleration to be added to the vehicle, and control the drive control system 4 to attain the additional deceleration, and, when the steering angle is decreasing, to set a yaw moment oriented in a direction opposite to that of a yaw rate being generated in the vehicle, as a target yaw moment to be applied to the vehicle, and control the brake control system 18 to apply the target yaw moment to the vehicle. Particularly, when the steering angle is 0, PCM 14 is configured to set the target yaw moment to 0 so as to terminate the control via the brake control system 18.
SWERVE ASSIST IN A TRANSPORTATION VEHICLE
A swerve assist to assist the driver of a transportation vehicle during an avoidance maneuver so that a collision with an obstacle is avoided. An additional steering torque for amplifying a current steering torque is applied when an avoidance maneuver of the transportation vehicle is detected. A single-wheel braking of the transportation vehicle is actuated to increase a transverse offset of the transportation vehicle.
Vehicle wheel steer control system and method
Steering a vehicle may include applying a net brake-steering force to a steered wheel sufficient to affect a steering moment upon the steered wheel sufficient to move the steered wheel away from a zero steering angle, and resisting movement of the steered wheel back toward the zero steering angle.
