The present invention provides a vehicle control device capable of improving fuel consumption while reducing deterioration of emission by appropriately controlling a powertrain system of a vehicle. 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 driving assistance device controls the speed of an own vehicle based on a predicted traveling state of a preceding vehicle, and includes a traveling scene recognition unit that detects the distance until the preceding vehicle reaches an intersection, a determination unit that determines a traveling scene of the preceding vehicle at the intersection, and a calculation unit that selects the preceding vehicle prediction model according to the traveling scene determined by the determination unit from among a plurality of preceding vehicle prediction models recorded for each traveling scene in which the preceding vehicle travels, and inputs a distance until the preceding vehicle detected by the traveling scene recognition unit in the selected preceding vehicle prediction model reaches the intersection so as to calculate a predicted traveling state of the preceding vehicle after a predetermined time.

Driving assistance device

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

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

Provided is a vehicle control device capable of reducing unease experienced by a driver and assisting a lane change of a vehicle. A vehicle control deviceassists a lane change of a vehicle, said device comprising: a visible range calculation unitthat calculates an area as a visible range by excluding the area occupied by preceding vehiclesfrom the area corresponding to the field of vision whilst driving; and a lane-change control unitthat conducts processing related to the lane change, on the basis of the calculated visible range. The lane-change control unitconducts processing related to the lane change on the basis of the visible range of the current-travel lane of the vehicle, and the visible range of the intended change-destination lane of the vehicle.

An internal combustion engine control device is provided. The internal combustion engine control device is provided with a generator that is driven by exhaust gas of the internal combustion engine. The internal combustion engine control device is capable of increasing the power generation of the generator. The internal combustion engine control device includes an exhaust amount control unit. The exhaust amount control unit increases the amount of the exhaust gas supplied to the generator in a coasting state.

Internal combustion engine control device

Provided is a fuel injection control device capable of accurately detecting a valve opening delay time of a fuel injection valve, and implementing high-precision minute injection control. A valve opening delay time of a fuel injection valve is estimated on the basis of a plurality of valve closing delay times obtained when the fuel injection valve is operated with injection pulse widths that are different injection pulse widths from each other and with which the fuel injection valve is in an intermediate lift state.
