The present invention obtains a controller and a control method capable of improving safety of adaptive cruise operation in a motorcycle.

In the controller for operation of the motorcycle, to which a surrounding environment detector is mounted, an adaptive cruise operation performing section controls deceleration to be generated by the motorcycle in adaptive cruise operation to be equal to or lower than an upper limit value or to be lower than the upper limit value, determines a collision possibility of the motorcycle on the basis of the upper limit value during the adaptive cruise operation, and performs warning operation that acts on a tactile organ of a rider of the motorcycle when determining that the collision possibility is high.

Provided is a vehicle travel control device capable of improving the usability of a following control by detecting dangerous behavior in a preceding vehicle, and differing the release timing of the following control. A vehicle travel control device having a preceding vehicle behavior recognition means for obtaining behavior information for a preceding vehicle, a preceding vehicle behavior determination means for detecting the degree of risk of dangerous behavior in the preceding vehicle from the behavior information, and determining the feasibility of a following control targeting the preceding vehicle on the basis of the detected dangerous behavior risk degree, and a vehicle operation control means for outputting an acceleration/deceleration/braking/steering control command to an actuator on the basis of the feasibility determination for the following control, wherein dangerous behavior is detected on the basis of the preceding vehicle behavior information, and the timing differs between a first release timing for the following control when a first dangerous behavior is detected and a second release timing for the following control when a second dangerous behavior different from the first dangerous behavior is detected.

A system includes a controller circuit configured to monitor, while a host vehicle is operated in a manual driving mode, a speed change response of an operator of the host vehicle based on a movement of a first vehicle traveling on a roadway, identify at least one speed parameter based on the speed change response, and apply, when the host vehicle is controlled in an autonomous driving mode, the at least one speed parameter based on the movement of a second vehicle traveling on the roadway.

The present invention obtains a controller and a control method capable of appropriately assisting with driving of a motorcycle by a rider.

A controller that controls operation of the motorcycle, to which a surrounding environment detector is mounted, includes: an acquisition section that acquires information on the surrounding environment of the motorcycle on the basis of output of the surrounding environment detector during travel of the motorcycle; and an adaptive cruise operation performing section that makes the motorcycle perform adaptive cruise operation on the basis of the surrounding environment information acquired by the acquisition section. The acquisition section acquires other vehicle travel state information that is information on a travel state of other vehicle acquired by a different vehicle from the motorcycle via wireless communication. The controller further includes a safety operation performing section that makes the motorcycle currently performing the adaptive cruise operation perform safety operation on the basis of the other vehicle travel state information acquired by the acquisition section.

Provided is an in-vehicle system in which an own vehicle does not decelerate according to a preceding vehicle even if the preceding vehicle changes lanes to the right turn lane or the left turn lane and decelerates after own vehicle entering an intersection area. A CPU 107 (first control unit) controls the own vehicle to follow the preceding vehicle. An image processing circuit 106 (detection unit) detects a lane marking of the traveling lane. The CPU 107 (determination unit) determines whether an own vehicle 201 has entered the intersection area. When the detection of one of the right and left lane markings of the traveling lane is interrupted (S20: YES) after the own vehicle 201 has entered the intersection area (S15: YES), the CPU 107 (second control unit) releases ACC that causes the own vehicle 201 to follow the preceding vehicle 202.

Provided are a travel control device that enhance safety while enabling smooth overtaking of a vehicle from tracking travel. This travel control device is equipped with a direction indication determination unit, a travel control unit that performs control to switch travel of the vehicle between tracking travel whereby the vehicle is made to travel by tracking the preceding vehicle and propulsion travel whereby the vehicle is made to travel so as to match the speed of the vehicle to a target speed, and an inter-vehicle distance detection unit that detects the inter-vehicle distance in tracking travel between the vehicle and the preceding vehicle. In cases in which, during tracking travel, it is determined that direction indication of vehicle has been activated and the inter-vehicle distance exceeds a prescribed distance, the travel control unit switches travel of the vehicle from tracking travel to propulsion travel.

Disclosed is a method for transmitting a vehicle-to-everything (V2X) message by a V2X communication device of a vehicle. The method for transmitting a V2X message by a V2X communication device of a vehicle comprises the steps of detecting a lane change of a target vehicle followed by the subject vehicle; setting a CACC mode on the basis of a preset operation determination for a lane change when the lane change of the target vehicle is detected; and transmitting a V2X message including information on the set CACC mode, wherein the CACC mode includes a single-lane CACC mode for providing a single-lane CACC service and a multi-lane CACC mode for providing a multi-lane CACC service.

A system includes a controller circuit configured to monitor, while a host vehicle is operated in a manual driving mode, a speed change response of an operator of the host vehicle based on a movement of a first vehicle traveling on a roadway, identify at least one speed parameter based on the speed change response, and apply, when the host vehicle is controlled in an autonomous driving mode, the at least one speed parameter based on the movement of a second vehicle traveling on the roadway.

The vehicle driving assist apparatus can execute at least one of an acceleration/deceleration control as a driving assist control to automatically accelerate and decelerate an own vehicle and a steering control as the driving assist control to automatically steer the own vehicle. The vehicle driving assist apparatus includes a driving assist restart switch operated by a driver of the own vehicle to restart the driving assist control. The vehicle driving assist apparatus does not restart the acceleration/deceleration control even when the driving assist restart switch is operated after stopping the acceleration/deceleration control in response to the driver performing an automatic acceleration/deceleration rejection operation. The vehicle driving assist apparatus does not restart the steering control even when the driving assist restart switch is operated after stopping the steering control in response to the driver performing an automatic steering rejection operation.
