The present invention provides a driving support device that performs driving support of a vehicle, comprising: a detector configured to detect a state of a driver of the vehicle; and a controller configured to control the driving support with a setting validated by the driver among a plurality of settings including a first setting and a second setting each of which requests the driver to perform a predetermined operation obligation, wherein the controller is configured to invalidate the second setting, in a case of determining that the driver does not fulfill the operation obligation from a detection result of the detector in a state where the second setting is validated.

Driving support device, vehicle, driving support method, and storage medium

A vehicle control device includes a display configured to display information, an inputter to which a user's operation is input, a driving controller configured to control at least one of a speed and steering of a vehicle, a determiner configured to determine a lane in which the vehicle is present when a first operation that allows a lane change by the vehicle is input to the inputter as a reference lane, and a display controller that is configured to cause the display to display a first image depicting a road on which the vehicle is present and a second image depicting the reference lane which are superimposed.

Vehicle control device, vehicle control method, and storage medium

A traveling control apparatus is configured to control automated driving traveling of a vehicle based on a set automated driving level. The traveling control apparatus comprises: an acquisition unit configured to acquire traveling scene information that specifies a traveling scene of the vehicle; and a control unit configured to perform offset control to offset a traveling position of the vehicle in a vehicle width direction to increase a distance to another vehicle traveling side by side with the vehicle. The control unit performs the offset control by setting one of a first mode and a second mode based on at least one of the traveling scene information and the automated driving level.

Traveling control apparatus, vehicle, and traveling control method

To provide a device to facilitate protection of a clutch while minimizing degradation of the torque transmission performance. A hydraulic clutch for drive power distribution is provided between a drive power source and auxiliary driving wheels, and a commanded torque is determined depending on the travel situation. The hydraulic pressure corresponding to the commanded torque is supplied to the hydraulic clutch. The surface temperature of the clutch is estimated (detected). The device generates a limiting value to limit the commanded torque when the difference in rotation between input and output shafts of the clutch is not less than a predetermined threshold and the commanded torque is not less than a predetermined value and performs control so as to increase the limiting value with an increase in the surface temperature of the clutch.

Hydraulic control device for drive power distribution device

A hydraulic control device for a vehicle is provided wherein a determination of 'base neutral' is made when a difference between a command hydraulic pressure and an actual hydraulic pressure of a hydraulic clutch is within a predetermined minute value range, and when the difference is out of the minute value range, a determination of 'base raising' is made if the command hydraulic pressure is larger than the actual hydraulic pressure, and a determination of &#x201c;base lowering&#x201d; is made if the command hydraulic pressure is smaller than the actual hydraulic pressure. The determination of &#x201c;sub raising&#x201d; is made when an inclination of command torque subjected to low-pass filter processing is positive for a predetermined time or more, and the determination of &#x201c;sub lowering&#x201d; is made when the inclination is negative for the predetermined time or more, whereby a rising or dropping tendency of the command torque is determined.

Hydraulic control device and method for vehicle

A device is provided which performs highly-accurate control in low-torque regions while taking advantage of hydraulic pressure sealed-type hydraulic control devices. The device includes: a first characteristic (sealed pressurization) obtained by closing the on/off valve and driving an oil pump: a second characteristic (sealed depressurization) obtained by disabling drive of the oil pump and opening the on/off valve; and a third characteristic (flow-rate control) obtained by opening the on/off valve and driving the oil pump. In the process of supplying hydraulic pressure to a piston chamber in a low torque region, the device performs control according to the third characteristic. In the process of pressurizing the piston chamber in a torque region higher than the low torque region, the device performs control according to the first characteristic. In the subsequent process of depressurizing the piston chamber, the device performs control according to the second characteristic.

A device is disclosed that performs highly accurate control in a low-torque region and improves the response of the hydraulic system, taking advantage of hydraulic sealed-type hydraulic control devices. The hydraulic sealed-type hydraulic control device includes: a first characteristic (sealed pressurization) obtained by closing an on-off valve and driving an oil pump; a second characteristic (sealed depressurization) obtained by disabling drive of the oil pump and opening the on-off valve; and a third characteristic (flow-rate control) obtained by opening the on-off valve and driving the oil pump. In a low-torque region, the device performs control according to the third characteristic. In a high-torque region, the device performs control according to the second characteristic. In the process of depressurization, the device performs control according to the second characteristic. Moreover, the device performs control to increase commanded hydraulic pressure in immediate response to an accelerator's change amount larger than a predetermined value.

A drive power distribution device includes a hydraulic pressure sealing-type hydraulic pressure control device for making an operation noise of an on-off valve such as a solenoid valve less recognizable to occupants of a vehicle. By closing the on-off valve and driving the oil pump, a hydraulic pressure detected using a hydraulic pressure detection means reaches a target hydraulic pressure, and fastening power of a hydraulic clutch is maintained at an oil pressure of hydraulic fluid sealed in an oil passage until the on-off valve is opened. The drive power distribution device closes the solenoid valve when the hydraulic pressure is detected to be equal to or less than a predetermined threshold hydraulic pressure and equal to or less than a predetermined threshold vehicle speed. This can prevent synchronization between an accelerator operation by a driver and a closing operation of the solenoid valve.
