A vehicle control system includes an automated driving control unit for controlling, based on surrounding environment information of a vehicle, driving, braking, and/or steering of the vehicle without depending on a driving operation of a driver; and a driving support control unit for supporting driving of the vehicle by the driver by controlling driving, braking, and/or steering of the vehicle. The control units are communicably connected. The driving support control unit can control, depending on a reception result of a signal received from the automated driving control unit, steering, and driving and/or braking of the vehicle based on the surrounding environment information without depending on the driving operation of the driver.

Vehicle control system and control method

A vehicle control device according to an embodiment includes a recognition unit configured to recognize a surrounding situation of a subject vehicle, a reception unit configured to receive an input of a set vehicle speed set by an occupant of the subject vehicle, and a driving control unit configured to control one or both of steering and acceleration or deceleration of the subject vehicle on the basis of the surrounding situation recognized by the recognition unit and the set vehicle speed received by the reception unit. In a case in which a plurality of traveling lanes on which the subject vehicle is able to travel in a progress direction of the subject vehicle are recognized by the recognition unit, the driving control unit determines a lane on which the subject vehicle travels among the plurality of traveling lanes on the basis of the set vehicle speed.

Vehicle control device, vehicle control method, and storage medium

A vehicle control system includes: a first switch that accepts an operation of an occupant of a vehicle; and a performance part that performs, when the first switch is operated, travel assist in a node in which an assist degree is the largest at that time point.

Vehicle control system, vehicle control method, and vehicle control program

A vehicle control device includes a recognizer and a driving controller. The driving controller operates at least in one of a first control state and a second control state in which a automation rate is higher than the first control state or a lower level of task is required of an occupant than the first control state. The driving controller does not suppress operation in the second control state if a traffic sign recognized by the recognizer is a sign indicating a speed limit equal to or higher than a predetermined speed and suppresses operation in the second control state if the traffic sign is a sign indicating a speed limit less than the predetermined speed.

A misfire detecting apparatus for an internal combustion engine is provided. The engine has an output shaft connected via a torsion element to an input shaft of a transmission mechanism. A transmission rotational speed parameter indicative of a rotational speed of the input shaft is detected. A modified engine rotational speed parameter is calculated by modifying the detected engine rotational speed parameter based on the transmission rotational speed parameter, an engine rotation moment on the input side of the torsion element, and a transmission rotation moment on the output side of the torsion element. An average change amount of the modified rotational speed parameter, and an inertia speed changing component, are calculated. Further, a corrected rotational speed parameter is calculated by correcting the modified rotational speed parameter according to the average change amount and the inertia speed changing component. A relative speed parameter is calculated based on the corrected rotational speed parameter, and a determination parameter is calculated by integrating the relative speed parameter. The misfire determination is performed based on the determination parameter.

Misfire detecting apparatus for internal combustion engine

The intent to exit a vehicle when a driver attempts to exit a vehicle is detected by an exit intent detection unit, and regardless of whether or not the shift range other than the parking range is detected by a shift range detection unit, a securing control unit controls a vehicle securing unit and secures the vehicle when an intent to secure is detected by a securing intent detection unit. Thus, unintended vehicle movement after exiting is suppressed by securing the vehicle in a stopped state during exiting.

Apparatus for controlling vehicle and control method

A hybrid electric vehicle drive apparatus has a setting portion for setting a limit value of a driving torque that a motor outputs when driving a hybrid electric vehicle by the power of the motor only, based on a maximum torque that the motor enables to output and a starting torque used to start an internal combustion engine by the motor. The setting portion sets the limit value to a first value and sets the limit value to a second value which is greater than the first value when a vehicle speed of the vehicle does not increase even though an accelerator pedal position degree increases while the vehicle is being driven only by the motor.

The objective of the present invention is to provide an evaporated fuel treatment device capable of performing a function diagnosis of a sealing valve with high accuracy even if an internal combustion engine is in operation. The evaporated fuel treatment device includes a sealing valve that blocks a fuel tank from the atmosphere, a canister, a canister internal pressure detection unit, a control part that performs an instruction for opening or closing the sealing valve and controls a purge, and a diagnostic part that performs a function diagnosis of an evaporated fuel sealing system including the fuel tank, the canister, and the sealing valve. The diagnostic part performs the function diagnosis of the sealing valve based on whether or not a canister internal pressure detected by the canister internal pressure sensor varies beyond a predetermined range.

Evaporated fuel treatment device

An evaporated-fuel processing apparatus including: a sealing valve which is arranged in a communication path between the atmosphere and a fuel tank mounted on a vehicle having an internal combustion engine, and shuts an internal space of the fuel tank off from the atmosphere; an open/close member which covers a fuel filling port of the fuel tank; a refueling-intention-information acquisition unit which acquires information indicating an intention of refueling; and a control unit which issues an opening command for opening the sealing valve when the refueling-intention-information acquisition unit acquires the information indicating an intention of refueling, and allows the open/close member to open when a time elapsed from the moment at which the opening command is issued exceeds a first predetermined time.

Evaporated-fuel processing apparatus

An evaporated fuel treatment apparatus includes a diagnosis section for leak diagnosis of an evaporated fuel tightly-closed system. In first diagnosis stage in which an atmosphere on-off valve is in close state after an ignition switch is turned off, the diagnosis section performs first leak diagnosis, based on relationship between tank internal pressure detected by a tank internal pressure sensor and first threshold value; and in second diagnosis stage in which the atmosphere on-off valve is in close state after completion of first leak diagnosis, the diagnosis section performs second leak diagnosis, based on relationship between tank internal pressure detected by the tank internal pressure sensor and second threshold value. The atmosphere on-off valve is once opened after completion of first leak diagnosis. First threshold value is set with larger deviation from the atmospheric pressure compared with second threshold value used in second diagnosis stage.

For each cylinder, an average value per cylinder of the sum of the integrated values of all the cylinders is calculated. For each cylinder, an error between the integrated value of the cylinder and the average value is calculated. For each cylinder, the output of the engine is controlled in accordance with the error calculated for the cylinder such that variations in the output between the cylinders are suppressed.
