VEHICLE DISTURBANCE HANDLING SYSTEM
A vehicle disturbance handling system to handle a disturbance that is an external force that acts on a vehicle and causes deflection of the vehicle, including: a disturbance detecting portion configured to determine an occurrence of the disturbance and to estimate a degree of influence of the disturbance; and a disturbance handling portion configured to handle the disturbance based on the estimated degree, wherein, when it is determined that the disturbance is occurring, the handling portion controls a brake device and a steering device of the vehicle to handle the disturbance, and wherein the handling portion is configured to determine a disturbance-handling braking force, which is a braking force that should be applied to the vehicle by the brake device to reduce the influence of the disturbance, and to gradually decrease the disturbance-handling braking force with a lapse of time from a time point of the occurrence of the disturbance.
VEHICLE CONTROL METHOD AND VEHICLE SYSTEM
A vehicle control method for a vehicle (1) comprises the steps: when an output torque of an engine (4) is equal to or greater than a given value, reducing the output torque in accordance with an increase in steering angle of the vehicle; setting, in accordance with a decrease in the steering angle, a first yaw moment instruction value whose direction is reverse to that of a yaw rate being generated in the vehicle; when the output torque is less than the given value, applying a braking force to road wheels, based on the first yaw moment instruction value; and, when the output torque is equal to or greater than the given value, applying a braking force to the road wheels, based on a second yaw moment instruction value smaller than the first yaw moment instruction value.
METHOD FOR ENDING A DRIVE OF A TRANSPORTATION VEHICLE
A method for terminating driving on the road shoulder by a transportation vehicle includes detection by a detection unit that the transportation vehicle is situated at least partially on a road shoulder, determination of a steering intensity of a manual steering maneuver, and assignment of one of at least two predetermined steering codes to the steering maneuver by a computing unit as a function of the steering intensity. An automatic intervention into a transportation vehicle control is carried out as a function of the assigned steering code.
Sensor integration based pedestrian detection and pedestrian collision prevention apparatus and method
An apparatus includes a front detection sensor detecting presence of a pedestrian on a driving lane of the vehicle, gaze information of the pedestrian, and a distance and a relative speed between the pedestrian and the vehicle; a vehicle sensor detecting at least one of a speed, an acceleration, a steering angle, a steering angular velocity, or a pressure of a master cylinder of the vehicle; an electronic control unit activating a function of a pedestrian detection and collision mitigation system based on information detected by the front detection sensor and the vehicle sensor; and a warning unit operated to inform a driver of a collision of the pedestrian with the vehicle by controlling the electronic control unit.
DEFLECTION CONTROL APPARATUS
A deflection control apparatus is configured to perform a deflection control in which a subject vehicle is deflected by a braking force difference between left and right wheels. The deflection control apparatus is provided with a releaser configured to release the deflection control if a steering operation, which is an operation of deflecting the subject vehicle in a direction opposite to a direction in which the subject vehicle is deflected by the deflection control, is detected during the deflection control. When releasing the deflection control, the releaser is configured to reduce a controlled variable over a predetermined time, which is shorter than a fall time of the controlled variable when the deflection control is ended without being released, and which becomes longer, as the controlled variable increases when the steering operation is detected.
Method for Activation and Deactivation of a Control Device
In a method for activating and deactivating a control unit which can be used to control an electrically activatable assembly, the control unit is switched between a waking state, a sleep state and a deactivated state, wherein in the sleep state, the control device is disabled but can be transferred into the waking state by means of a sensor signal.
Vehicle control apparatus and method for controlling vehicle
Disclosed herein are a vehicle control apparatus and a method for controlling a vehicle using the same. The vehicle control apparatus according to an embodiment of the present invention includes an input unit that receives handle operation information detected by a sensing device, receives avoidance steering information of a driver, and receives behavior information of a vehicle, a determination unit that determines whether the vehicle is in an emergency steering avoidance state based on the received handle operation information, the received avoidance steering information of the driver, and the received behavior information of the vehicle, and a control unit that controls an evasive handling control (EHC) system and an electronic stability control (ESC) system such that the EHC system presses wheels in advance ahead of the ESC system to perform a braking operation according to a target wheel pressure value, when the vehicle is in the emergency steering avoidance state.
VEHICLE DRIVE SYSTEM
A vehicle drive system configured to achieve a required driving force of braking force without changing an orientation of a vehicle in the event of slippage of a wheel. The vehicle drive system comprises: a torque generating device; a differential mechanism that allows a relative rotation between a right wheel and a left wheel; a differential restricting device that restricts a differential rotation between the right wheel and the left wheel; and a steering mechanism that controls a turning angle of pairs of the wheels. A first controller controls the relative rotation between the right wheel and the left wheel to be smaller than a predetermined value and second controller further controls a turning angle of the wheels controlled by the steering mechanism.

Deflection control apparatus
A deflection control apparatus is configured to perform a deflection control in which a subject vehicle is deflected by a braking force difference between left and right wheels. The deflection control apparatus is provided with a releaser configured to release the deflection control if a steering operation, which is an operation of deflecting the subject vehicle in a direction opposite to a direction in which the subject vehicle is deflected by the deflection control, is detected during the deflection control. When releasing the deflection control, the releaser is configured to reduce a controlled variable over a predetermined time, which is shorter than a fall time of the controlled variable when the deflection control is ended without being released, and which becomes longer, as the controlled variable increases when the steering operation is detected.
