摘要: A automatic driving control apparatus for a vehicle can selectively switch a driving mode between a manual driving mode in which a driver manually performs driving operation of the own vehicle and an automatic driving mode in which driving operation is performed automatically along a set target traveling route. The automatic driving control apparatus includes a driving skill evaluation unit and a driving mode switching unit. The driving skill evaluation unit is configured to monitor the driving operation by the driver during traveling in the manual driving mode and evaluate a driving skill of the driver. The driving mode switching unit is configured to control the driving mode so as to be switchable to the automatic driving mode on condition that at least an evaluation value of the driver by the driving skill evaluation unit exceeds a threshold set in advance.

摘要: A difference in a longitudinal force indicating a difference between the longitudinal force acting on left and right wheels is obtained. A correction amount of the longitudinal force acting on each wheel is calculated based on the difference in the longitudinal force, and each wheel is independently controlled. When the difference in the longitudinal force is obtained, a speed increasing ratio of a front wheel steering angle for changing an overall steering ratio is calculated based on a preset control map and an input parameter including a vehicle speed and a lateral acceleration or the vehicle speed and steering wheel angle. A yaw moment to be generated around a weighted center of the vehicle is calculated based on the speed increasing ratio and a steering wheel angle of the vehicle as the input parameter. The difference in the longitudinal force is then calculated based on this yaw moment.

摘要: A system according to the present disclosure includes an actuator control module and a damping ratio module. The actuator control module is configured to control an actuator of a vehicle to cause the vehicle to perform a yaw maneuver by rotating about its yaw axis. The damping ratio module is configured to determine a damping ratio based on an operating parameter measured during the yaw maneuver. The operating parameter includes at least one of a yaw rate of the vehicle, a yaw rate of a trailer connected to the vehicle, a lateral acceleration of the vehicle, a lateral acceleration of the trailer, a heading angle of the vehicle, and a hitch angle between a longitudinal axis of the vehicle and a longitudinal axis of the trailer.

摘要: A vehicle driving support device issues an alert to notify a driver of a vehicle that there is a possibility of occurrence of a situation in which the vehicle is not able to travel along a lane. The vehicle driving support device issues an alert when an alert condition that a rate of increase in a lateral acceleration of the vehicle is equal to or larger than a predetermined rate of increase is satisfied.

摘要: An ADK is attachable to and removable from a VP and issues an instruction for autonomous driving to the VP. The VP includes a steering system for steering of the VP. (An ADS of) the ADK includes a compute assembly and communication module configured to communicate with the VP. The compute assembly obtains from the VP, a prescribed reference on which control of a wheel steer angle is premised, calculates the steer angle in accordance with a driving plan for autonomous driving based on the obtained prescribed reference, and transmits a wheel steer angle command indicating the calculated steer angle to the VP. When the attachable and removable ADK that issues the instruction for autonomous driving controls the VP, without storage of the prescribed reference on which control of the wheel steer angle is premised in advance in the ADK, control suited to a base vehicle can be carried out.
