A vehicle control device includes: a prediction unit configured to predict speeds or accelerations of a vehicle based on a plurality of prediction models; a fuel consumption information calculation unit configured to calculate fuel consumption for each of a plurality of prediction results obtained by the prediction unit; a selection unit configured to select any one of the plurality of prediction results; and a powertrain control unit configured to control at least one of an engine, a generator, an inverter, a drive motor, and a transmission of the vehicle based on the prediction result selected by the selection unit.

Vehicle control device and vehicle control method

Provided is a vehicle control device capable of realizing fuel-efficient traveling of an own vehicle. Therefore, a vehicle control deviceincludes a limiting factor determination unitthat determines whether there are a limiting factor on an own lane that limits traveling of an own vehicle in the own lane and a limiting factor on an adjacent lane that limits the traveling of the own vehicle in a lane adjacent to the own lane, a lane selection unitthat selects a lane in which the own vehicle travels based on a determination result of the limiting factor determination unit, and a driving force control unitthat controls a driving force of the own vehicle based on the lane selected by the lane selection unit

Vehicle control device

A motion control device for a moving body is configured to control a motion of a moving body and includes a movement distance acquisition unit, a movement distance storage unit, a movement distance prediction unit, a control determination unit, and an acceleration/deceleration control unit. The acceleration/deceleration control unit performs control of the acceleration/deceleration in the movement direction of the moving body based on a determination result on whether to suppress the acceleration/deceleration of the moving body performed by the control determination unit and the second movement distance predicted by the movement distance prediction unit.

Motion control device for moving body

Example implementations described herein involve a system for predicting vehicle behavior with a higher efficiency which can reduce the number of sensors and the amount of data needed for vehicle control systems. Example implementations described herein can be used for any type of vehicle control system, such as a powertrain control system, an adaptive cruise control system, an autonomous driving system, because the target vehicle to be predicted can be replaced to a preceding vehicle, a surrounding vehicle, and an ego vehicle.

System for predicting vehicle behavior

Provided and disclosed herein is a vehicle travel control device capable of improving fuel consumption performance of a host vehicle by, in response to receiving vehicle information indicating a deceleration cause has occurred ahead of the host vehicle, rapidly stopping or suppressing the generation of a driving force by the host vehicle.

Vehicle travel control device, and vehicle travel control system

The movement of the vehicle is controlled so that the travel time does not become long while reducing the fuel consumption of the vehicle. A vehicle control devicethat automatically controls a speed of a vehicle is configured to include an acceleration/deceleration pattern setting unitthat sets a plurality of acceleration/deceleration patterns including acceleration and deceleration in a traveling scheduled zone and sets the speed to be the same in a region between an acceleration region and a deceleration region in each acceleration/deceleration pattern based on traveling history in a traveling scheduled zone.

A vehicle control device includes a determination unit, a speed control unit, and a recommended speed acquisition unit. The recommended speed acquisition unit acquires a first recommended speed, being a new recommended speed related to a first section. The determination unit determines a magnitude relationship between the first recommended speed and the first recommended speed. The speed control unit controls the speed of the vehicle to be maintained at a speed of the first recommended speed in the first section when the determination unit determines that the first recommended speed is less than the first recommended speed.

Vehicle control device, vehicle control method, and vehicle

When acceleration control is interrupted due to a lane change or the like, the engine speed is controlled from a high rotation speed to a low rotation speed, a variation in engine speed increases, and poor driver's driving performance is brought about. Furthermore, suppression of acceleration when there is a lane change possibility may rather cause the lane change and the driver feels discomfort. The vehicle control unit according to the present invention includes a target engine speed calculation unit which corrects a target engine speed to be reduced relative to a predetermined target engine speed when the acceleration/deceleration possibility determination unit determines that there is a deceleration possibility during acceleration to a target vehicle speed in automatic acceleration/deceleration control, and an engine control unit which controls an engine to have a target engine speed corrected by the target engine speed calculation unit.

The present invention is directed to a novel road information recognition system capable of highly accurately estimating the positions of lane markers to be located on the far side of a lane after change of lane. The present invention is equipped with a front lane marker detection means for detecting, by using a front imaging means, lane markers located ahead of a host vehicle; a side lane marker detection means for detecting, by using a side imaging means, the positions of lane marker located on both sides of the vehicle and a lane width; and a front lane marker estimation means for estimating the positions of the lane markers to be located on the far side of the lane after change of lane on the basis of the information regarding the lane markers located ahead of the vehicle, which is obtained by the front lane marker detection means, and the positions of the lane markers located on the sides of the vehicle and the lane width, which are obtained by the side lane marker detection means.

Road information recognition system and road information recognition method

An engine is driven at an operating point with high engine efficiency to improve fuel economy. A vehicle control device according to the present invention controls a transmission ratio before increasing the engine rotation speed, and thereafter, engages the clutch.

A hydraulic working machine has an assist electric motor connected to an engine and a hydraulic pump. The emissions of air pollutants in the exhaust gas from the engine are minimized regardless of fluctuations in the load torque of the hydraulic pump. A specific revolution speed suitable for reducing the emissions of air pollutants is stored, and an engine is controlled using the specific revolution speed as a target revolution speed. The absorption torque of a hydraulic pump is subjected to high-pass filtering whereby a high-frequency component devoid of a trend component is obtained. Target assist torque is computed from the high-frequency component, and the assist electric motor is subjected to power running/generation control accordingly. A specific output torque range suitable for reducing the emissions of air pollutants is stored, and the target assist torque is corrected so that the trend component does not exceed the specific output torque range.

It is an object to provide a lane departure warning device capable of generating almost no false warning if a driver performs an avoiding operation of a lane departure. The lane departure warning device estimates the steering amount of the own vehicle toward the center of the lane or the amount correlating with this steering amount based on the parameter representing the vehicle behavior such as the steering angle, the yaw rate and the lateral G, thereby detecting the state of the vehicle steering toward the center of the lane when a driver is performing an avoiding operation to avoid the lane departure (quick steering), and determining whether or not the possibility of the vehicle's departure from the lane is high without using the time TLC and its threshold value Ts, but only based on the determination whether or not the distance Dor Dfrom the outer edge of the front wheel to the marking line is less than the threshold value Ds if the driver performs the avoiding operation to avoid the lane departure (quick steering).
