A vehicle control method for controlling a vehicle using a vehicle control apparatus includes: a sensor configured to detect a state outside a subject vehicle; and a control device. The vehicle control method includes: executing control of recovering a travel trajectory of the subject vehicle to a target trajectory, as ordinary control, by giving a steering amount in a lateral direction with respect to a travel lane of the subject vehicle; using detection data of the sensor to determine whether or not another vehicle is traveling in an adjacent lane to the travel lane of the subject vehicle; and when determining that the other vehicle is traveling in the adjacent lane ahead of the subject vehicle, increasing a response of the steering amount to a higher response than that in the ordinary control, before the subject vehicle passes the other vehicle.

A road surface friction coefficient estimating device includes an electronic control unit. The electronic control unit is configured to: compute a system noise variance value as an index indicating a degree of variation in a road surface friction coefficient estimation value; compute an observation noise variance value as an index indicating a degree of variation in observation noise; compute, with regard to an observation deviation, an index indicating a degree of shift of the observation deviation that is newly obtained as to an index indicating a degree of past variation in the observation deviation; compute the index as a friction coefficient change amount; compute a Kalman gain; and add in the friction coefficient change amount when computing the system noise variance value.

An embodiment of the present invention provides higher ride comfort to a driver in control of steering and suspension. An ECU (600) includes: a steering control section (610) which controls a magnitude of an assist torque or a reaction torque; and a suspension control section (650) which controls a damping force of a suspension. The steering control section (610) refers to a state of a vehicle which state is predicted by the suspension control section (650), and the suspension control section (650) refers to a steering torque.

An operating system for an automated vehicle includes a failure-detector and a controller. The failure-detector detects a component-failure on a host-vehicle. Examples of the component-failure include a flat-tire and engine trouble that reduces engine-power. The controller operates the host-vehicle based on a dynamic-model. The dynamic-model is varied based on the component-failure detected by the failure-detector.

A vehicle control device includes a setting part that sets a target area which is an area used as a target when the host vehicle changes lane, a derivation part that derives a first time period which is a time length required from a start to a termination of a lane change by the host vehicle, and a second time period which is a time length required for a following reference vehicle, traveling at rear of the target area, to catch up with a preceding vehicle traveling in front of the host vehicle, a determination part that determines that the lane change by the host vehicle is possible, in a case at least a condition in which that the first time period is shorter than the second time period is satisfied, and a controller that performs the lane change of the host vehicle.

A computer includes a processor and a memory storing instructions executable by the processor to determine, for a host vehicle operating in a first operation mode, a first operation mode transition location based on a time to transition the host vehicle from the first operation mode to a second operation mode, a current speed of the host vehicle, and a distance from the host vehicle to an operation mode transition boundary location, to determine a second operation mode transition location that is a specified distance from the first operation mode transition location, the specified distance based on the current host vehicle speed, to transition from the first operation mode to the second operation mode upon reaching the first operation mode transition location, and to transition from the second operation mode to the first operation mode when the second operation mode transition location is between a current location of the host vehicle and the operation mode transition boundary location.

A method of controlling braking when steering an in-wheel motor vehicle includes monitoring a required tire rotation angle for each steering angle and an actual tire rotation angle when performing cooperative control of an in-wheel motor for reducing a steering load, and generating a vehicle braking force in a case where the actual tire rotation angle exceeds the required tire rotation angle, thereby easily preventing a vehicle-skidding phenomenon.

Provided is a driver assistance system including an internal camera installed in a vehicle to detect whether a driver is in a drowsy driving, and configured to photograph a state of eyes of the driver to acquire drowsiness data, a first sensor installed in the vehicle to have a front-side view of the vehicle, and configured to acquire first sensor data to detect an object in the front-side view, a second sensor installed in the vehicle to have a rear-side view of the vehicle and configured to acquire second sensor data to detect an object in the rear-side view, and a controller including at least one processor configured to process the drowsiness data, the first sensor data, and the second sensor data, wherein the controller is configured to: if a result of processing the drowsiness data is that the driver has closed the driver's eyes for a predetermined time or longer, transmit a control signal to at least one of a braking device or a steering device to perform a lane change for stopping the vehicle based on a result of processing the first sensor data and the second sensor data.

According to an embodiment, a vehicle control system includes: a determination unit determining a schedule of a running locus and speed control of a subject vehicle; a running control unit automatically performing at least speed control of the subject vehicle on the basis of the schedule determined by the determination unit; and an interface control unit causing a display unit to display information representing a position or a section at which the subject vehicle accelerates or decelerates in the speed control in association with information representing the running locus on the basis of the schedule determined by the determination unit.

A driver state determination unit of a drive mode switching control device regularly or irregularly determines whether a driver's state is a state of being able to perform a driving operation in a manual drive mode. The drive mode switching control device determines whether an operation performed by the driver is an emergency override operation or a non-emergency override operation. The drive mode switching control device outputs a switching signal for switching an automatic drive mode to the manual drive mode when a determination result by the driver state determination unit immediately before detection of the emergency override operation is that a driver's state is a state of being able to perform a driving operation in the manual drive mode.
