Abstract

A vehicle seat adjustment device includes a first adjustment mechanism, a second adjustment mechanism, and a controller. The first adjustment mechanism is moved in a first direction upon driving of a first motor to adjust a position of a vehicle seat. The second adjustment mechanism is moved in both the first direction and a second direction orthogonal to the first direction upon driving of a second motor to adjust the position of the vehicle seat. The controller controls and drives the first motor and the second motor. A speed at which the second adjustment mechanism is moved in the first direction is lower than or equal to a speed at which the first adjustment mechanism is moved in the first direction. When the second motor needs to be driven, the controller drives the second motor while driving the first motor.

Abstract

When it is confirmed that a user exists based on an image of the situation outside a vehicle which is captured using a camera and a proximity sensor detects a fact that the user is approaching based on, for example, a putting of a hand of the user over the proximity sensor, a control device causes a ramp to be extended. As such, a user sitting in a wheelchair can cause the ramp to be extended by approaching the proximity sensor, such as the putting of the user's hand over the proximity sensor such that the user sitting in the wheelchair does not have to press an extension/storage button provided on the vehicle to cause the ramp to be extended.

Abstract

A protrusion is formed on a first part of an inner-cabin side wall of an installation base member of a protector with a sensor. The first part is closer to a connecting wall than a second part opposite the first part. The protrusion is on a virtual line in cross section. The virtual line is where convex substances, keys for example, hanging on passengers' clothes conceivably pass through. The virtual line extends toward a connecting point from a rear part of an automobile body closer to an interior of the automobile body than a reference line. The reference line is parallel with a direction in which a flange protrudes and extends from the connecting point. The connecting point is a part of an inner-cabin side end of a hollow part closest to an interior of the automobile body. The inner-cabin side end is connected with the installation base member.

Abstract

A step device for a vehicle includes a movable step and a coupling member. The movable step includes a guide rail. The coupling member is configured to cause the movable step to move from a deployed position to a retracted position as a engaging part comes into sliding contact with a side wall of the guide rail that is located on an inner side in a vehicle width direction and, while pressing the side wall, moves inside the guide rail in a direction of closing a sliding door. The guide rail is configured such that a terminal end region on a closing side including a terminal end position at which the engaging part is located when the sliding door is fully closed constitutes a closing-side free running zone in which the engaging part does not press either of the side walls.

Abstract

A cooling apparatus for an internal combustion engine includes a pump, a radiator, a flow rate adjustment valve, a bypass passage, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a valve member biasing component that biases the valve member in a valve-closing direction in which the open degree decreases. The valve member rotates in a valve-opening direction in which the open degree increases when a pressure difference increases between positions upstream and downstream of the valve member in a flow direction of coolant in the circulation circuit and rotate in the valve-closing direction when the pressure difference decreases. The controller increases the pump discharge amount as a target radiator flow rate that is a target of an amount of coolant passing through the radiator increases.

Abstract

A fragile portion is provided at a portion of a vertical frame bar. When an impact load from under a vehicle is applied to a grille shutter, the impact can be at least partially absorbed as the fragile portion undergoes plastic deformation (including damage). Thus, the impact exerted on a portion of the vertical frame bar other than the fragile portion is mitigated, and a fin can be restrained from coming off a frame. Moreover, the fin can be restrained from coming off the frame by a compact structure, because simply providing the fragile portion at a portion of the vertical frame bar can achieve that.

Abstract

A control device for an onboard engine is configured to control the oil discharge pressure of an oil pump and execute, when determining that there may be an abnormality in the control of the oil discharge pressure, a change process that increases the target discharge pressure to a value that is greater than that before it is determined that there may be an abnormality in the control. When a discharge pressure sensor value in a situation in which the discharge pressure is being controlled based on the target discharge pressure increased through execution of the change process does not become greater than or equal to a discharge pressure threshold, the control device sets an upper limit for the engine rotation speed and increases the upper limit as the discharge pressure sensor value increases.

Abstract

A vehicle theft prevention device includes: a device control unit that starts, when performing exit processing for causing a vehicle to move from a parking position to a user position by an autonomous driving control of the vehicle in response to an exit instruction to the vehicle from a terminal of the user outside the vehicle, performing first change processing for changing a state of facilities in a vehicle cabin of the vehicle from a theft prevention state in which theft of the vehicle and articles in the vehicle cabin is prevented to a normal state in which the vehicle is able to be driven by the user such that the first change processing ends when the vehicle arrives at the user position.
