The present invention prevents occurrence of abnormal noise and swing of a vehicle in mitigating braking force of a steered wheel while reducing a steering load at the time of stationary steering to reduce a burden of a steering device and reducing stress accumulation due to stationary steering to reduce burdens of a tire, a suspension device and the steering device. The present invention includes a stop braking force control unitthat individually controls braking forces of steered wheelsandand non-steered wheelsandat the time of deceleration of the vehicle, and a pre-detection unitthat detects steering in a stopped state of the vehicle in advance, in which the stop braking force control unit executes, when the steering in a stopped state of the vehicle is detected in advance by the pre-detection unit, braking force mitigation control to decrease the braking forces of the steered wheels to be lower than the braking forces at the time of normal braking.

A parking assistance apparatus is provided that is capable of improving convenience for a driver by determining that parking is possible in a case where the local vehicle will protrude from a parking frame but safety is ensured around a prescribed position that corresponds to the parking frame. The presence/absence of an obstacle around a prescribed position that corresponds to a parking frame is also determined for a parking frame from which the local vehicle will protrude. In a case where safety is ensured around the prescribed position that corresponds to the parking frame, it is determined that parking is possible, and the location of the parking frame is presented to a driver.

There is proposed a gearshift control device which can reduce a transmission load due to preshift, and improve fuel efficiency of a vehicle. A gearshift control device which controls a transmissionincluding two systems of power transmission mechanisms, and preshifts the transmissionbased on a traveling plan during automatic driving of a vehicle. The gearshift control device makes automatic driving preshift execution decision of planning control contents of the transmissionbased on the traveling plan, and preshift execution decision of deciding whether or not to preshift the transmission based on a control plan of the transmission

Transmission control device

The present invention improves fuel efficiency of a vehicle and decreases a noise, by decreasing a margin value of a hydraulic pressure supplied to a hydraulic pressure control target and decreasing the hydraulic pressure supplied to the hydraulic pressure control target, when the vehicle is driven automatically. In a hydraulic pressure control devicefor a vehicle that controls a line pressure or an operation pressure (hydraulic pressure) supplied to a clutchor a transmission(hydraulic pressure control target) provided in the vehicle, the hydraulic pressure control deviceincludes an operation pressure control unit(hydraulic pressure setting device) that sets margin values &#x3b1;and &#x3b1;of the operation pressure (line pressure) supplied to hydraulic circuitsandof the clutchor the transmission, on the basis of a predetermined driving plan (refer to FIG.) in the case of driving the vehicle automatically.

The present invention proposes a transmission control device capable of shortening a switching time between forward control and reverse control of a transmission. The present invention relates to a transmission control device that controls a transmission, including: a forward power transmission mechanism configured to move a vehicle forward; and a reverse power transmission mechanism configured to reverse the vehicle. Each of the forward power transmission mechanism and the reverse power transmission mechanism includes a driving-side connector and a driven-side connector. The forward power transmission mechanism and the reverse power transmission mechanism are configured to be capable of changing a contact state where the driving-side connector and the driven-side connector are pushed to contact each other, a retracted state where pushing forces are released to retract the driving-side connector and the driven-side connector, and an intermediate state formed as the intermediate state between the contact state and the retracted state. When the vehicle is controlled based on a previously-generated control content including switching between forward control and reverse control, one of the forward control and the reverse control is performed by controlling one power transmission mechanism between the forward power transmission mechanism and the reverse power transmission mechanism to the contact state while controlling the other power transmission mechanism to the intermediate state.

A welding state inspection method for ultrasonic-welded plate-like members includes the steps of measuring energy that has been transmitted to an anvil when ultrasonic-welding a plurality of plate-like members stacked on the anvil while pressing a horn that vibrates against the plate-like members; and determining a quality of a welding state of the plate-like members on the basis of the energy measured in the measuring step.
