A vehicle driving assistance apparatus predicts (i) a first consumed energy amount corresponding to a consumed energy amount consumed by a driving apparatus of an own vehicle when executing a first following control and (ii) a second consumed energy amount corresponding to the consumed energy amount consumed by the driving apparatus of the own vehicle when executing the second following control. The apparatus executes the second following control when the second consumed energy amount is smaller than the first consumed energy amount. On the other hand, the apparatus executes the first following control when the second consumed energy amount is equal to or greater than the first consumed energy amount.

There is provided an adaptive cruise control method for autonomously adapting the speed of an ego vehicle (300) to maintain a target headway, headway being distance from the ego vehicle to a forward vehicle (302), the ego vehicle equipped with a perception system (100) for measuring a current headway and a current speed and acceleration of the forward vehicle relative to ego vehicle, the method comprising: in response to detecting that the current headway is below the target headway, determining and implementing a deceleration strategy for increasing to the target headway; wherein the deceleration strategy is determined so as to selectively optimize for comfort in dependence on a predicted headway, the predicted headway computed for a future time instant based on the current speed and acceleration of the forward vehicle relative to the ego vehicle.

A braking control apparatus to be installed an electric vehicle includes an acceleration and deceleration operation member, a controller, and a recognizer. The acceleration and deceleration operation member receives an acceleration request in accordance with an operation amount in a first direction from a neutral position, and receive a deceleration request in accordance with an operation amount in a second direction from the neutral position. The controller controls an amount of power regenerated by a rotary electric machine driven by wheels in accordance with the operation amount in the second direction. The recognizer recognizes a preceding vehicle traveling ahead of the electric vehicle. Upon detection of the preceding vehicle at a relative distance from the electric vehicle that is equal to or less than a threshold, the controller performs braking suppression control to decrease the amount of power regenerated in accordance with the operation amount in the second direction.

A broadcast of a signal is received at a first system from a second system at a first time. From the signal, a location of a target associated with the second system and a velocity of the target are determined relative to a location of the first system and a velocity of the first system. At the first system, using the location and the velocity of the first system and using the location and the velocity of the target, a likelihood is computed of a collision between the first system and the second system. A notification is sent from the first system about the likelihood of collision responsive to the likelihood of collision exceeding a threshold likelihood.

A vehicle and an adaptive cruise control system (ACC) is provided. The ACC comprises a steering wheel system with a steering wheel arranged to allow the provision of manual steering input to the steering system of the vehicle and a steering angle sensor, wherein the steering system is configured to identify a specific momentary manual steering wheel actuation by comparing data from the steering angle sensor with predetermined thresholds, and to select a next one of the moving or stationary objects in the surroundings in front of said vehicle to control the speed of said vehicle in relation to, based on the direction of the specific momentary manual steering wheel actuation indicated by the steering angle sensor.

A vehicle identification system includes a communication device receiving other vehicle information related to other vehicle around a host vehicle, a detection device detecting other vehicle around the host vehicle, and a vehicle identification device identifying a vehicle transmitting the other vehicle information on the basis of the other vehicle information received by the communication device and the detection device, wherein the vehicle identification device is switching between a capturing mode capturing the transmitting vehicle on the basis of the other vehicle information received by the communication device and the detection device, and a tracking mode identifying the transmitting vehicle on the basis of a positional relation between the host vehicle and the transmitting vehicle at the time of the capturing mode, and motion information related to the transmitting vehicle based on the other vehicle information received by the communication device, after the capturing mode.

An escape-path-planning system to operate an automated vehicle includes an object-detector and a controller. The object-detector is suitable for use on a host-vehicle. The object-detector is used to detect an other-vehicle in an adjacent-lane next to a present-lane traveled by the host-vehicle. The controller is in communication with the object-detector. The controller is configured to, in response to a lane-change-request, determine a first-route-plan that steers the host-vehicle from the present-lane to the adjacent-lane, determine a second-route-plan that steers the host-vehicle into the present-lane, initiate the first-route-plan when a forecasted-distance between the other-vehicle and the host-vehicle is greater than a distance-threshold, and cancel the first-route-plan and select the second-route-plan when the forecasted-distance between the other-vehicle and the host-vehicle becomes less than the distance-threshold after the first-route-plan is initiated. The second-route-plan is a pre-planned escape-path that is instantly available if needed that provides a smoother travel-experience for an occupant of the host-vehicle.

This vehicle control device includes: a distance measurement unit that measures the distance between a vehicle and a preceding vehicle; and an engine control unit that starts up an engine when, in comparison to a distance measured by the distance measurement unit once a host vehicle has stopped and an engine mounted in the host vehicle has stopped, a distance newly measured by the distance measurement unit increases by at least an offset amount that indicates the amount of increase in distance used to determine whether to start up the engine.

A device for setting a target vehicle that sets a target vehicle to be subjected to driving assistance control of a host vehicle includes: a detection signal acquisition device capable of acquiring a first detection signal representing an object by an image, and a second detection signal representing the object by a reflection point; and setting control unit, which determines whether to set a forward object as a target vehicle, wherein if a movement history is not associated with the forward object, and a combination history is associated with the forward object, then as a selection threshold of a first determination parameter for determining whether to set the forward object as the target vehicle, a selection threshold is used such that the forward object is less likely to be selected as the target vehicle than with the selection threshold which would be used if a movement history is associated with the forward object.

A control system for a subject vehicle includes an autonomous braking system, a forward monitoring sensor and a rearward monitoring sensor. The controller monitors a first speed of a first vehicle travelling in front of the subject vehicle and a second speed of a second vehicle travelling to the rear of the subject vehicle. A first gap-closing time is determined based upon the speed of the subject vehicle and the first speed of the first vehicle. A second gap-closing time is determined based upon the speed of the subject vehicle and the second speed of the second vehicle. The controller controls the speed of the subject vehicle based upon the first gap-closing time and the second gap-closing time when one of the first gap-closing time or the second gap-closing time is less than a first threshold time.
