An electric power-steering device has a speed-reducing mechanism (17) for reducing the speed of an output shaft (16) of an electric motor (15). The speed-reducing mechanism (17) has an internal gear (39) engaged and rotated with the output shaft (16) and an external gear (40) with which the internal gear (39) internally meshes. A drive pulley (41) rotatable together with the external gear (40) and a driven pulley (42) provided so as to surround a steering shaft are connected by an endless belt (43). Speed reduction is obtained by the internal gear (39) and the external gear (40), and the speed-reducing mechanism (17) as a whole achieves a high reduction ratio without greatly reducing the diameter of the drive pulley (41).

Electric power-steering device

A parking assist device detecting a parking stall line from an image, which is captured by a capturing portion; setting a parking target position on the basis of the parking stall line; and assisting the vehicle to travel to the parking target position; the parking assist device includes a vehicle detecting portion for detecting a movement of the vehicle, a memorizing portion for memorizing the movement detected by the vehicle detecting portion, as a vehicle moving trajectory, a temporary parking target position estimating portion for assuming a temporary parking target position on the basis of variations of the vehicle moving trajectory, which has been memorized by the memorizing portion, and a parking stall line searching area setting portion for setting a parking stall line searching area, within which a parking stall line is searched on the basis of the temporary parking target position

Parking assist device

A parking assistance device has guidance means for guiding a vehicle to an initial position for parking which position enables parking of the vehicle to a space that is a space next to a tangible object around the vehicle and is located on the far side of the vehicle with respect to the direction of advancement of the vehicle; obstacle detection means for detecting an obstacle around the vehicle based on a reflected wave of a wave emitted from the vehicle in a predetermined direction; and timing setting means for setting a guidance start timing based on the result of the detection made by the obstacle detection means on the obstacle in the parking space within a predetermined distance from the tangible object.

Parking assistance device

A parking assist apparatus (1) has: an identifying portion (2a) that identifies a target parking position when the vehicle is at a temporary stop position having a predetermined positional relation with the target parking position; a parking-assisting portion (2b) that assists steering operation of a driver of the vehicle based on the target parking position when parking the vehicle. For facilitating the driver to visually confirm a positional relation between a specific portion of the target parking position and the vehicle, the parking assist apparatus includes at least one of a polarizing film (8), auxiliary mirror (12), member (22,32) provided on a vehicle mirror and extending in the vehicle lateral direction, transparent portion (42) provided in a passenger-side door, adjusting device (53) that adjusts the direction of the lower edge of the vehicle mirror, irradiating device (74) that radiates a laser, optical-axis adjusting portion (83) that adjusts an optical axis of a headlight of the vehicle.

Parking assist apparatus

A parking assist apparatus includes a CPU for obtaining image data from a camera mounted on a vehicle, an image memory for storing the obtained image data as recorded image data, and an image processor for recognizing an object based on the image data. The image processor determines when to display a parking assist image to reveal an area hidden as a blind spot of the camera when the recognized object is in the blind spot of the camera and displays the parking assist image combining both current image data and the recorded image data for the area currently hidden as the blind spot of the camera, together with an indicator indicating the current position of the vehicle superimposed on the display.

Parking assist method and a parking assist apparatus

Parking assist apparatus and method cause a vehicle driver to set a target parking position in which the vehicle is to be parked by prompting the driver to specify the position of a parking space frame in the screen of a touch display by touch-operating arrow button switches shown in the screen, and then calculate a path to the target parking position. If a path to the target parking position is not generated by calculation, the arrow button switches for moving the parking space frame in such directions that a path will not be generated (i.e., the vehicle cannot be parked), among all the arrow button switches, are made non-displayed or are displayed dimmer than the other arrow button switches, and are disabled.

Parking assist apparatus and parking assist method for vehicle

A driving assist apparatus for a vehicle that guides the vehicle to a target position is provided. On the basis of the present direction of the vehicle and the direction of the vehicle at the target position, a basic path that changes the vehicle direction so as to coincide with the target direction of the vehicle at the target position is computed. A path from the present position to the target position is computed by adding a straight-line path to the basic path under a predetermined condition.

Driving assist apparatus and method for vehicle

A vehicle backward movement assist device includes a vehicle path determining means for determining a path from a current position of the vehicle moved at a moving amount detected by a vehicle moving amount detecting means to a first target position or a second target position, the vehicle path determining means determining the path by repeatedly calculating the path, and a displaying means for displaying an image of a rear view from a captured by an image capturing means, the displaying means superimposing the first or second target position of the vehicle moved based upon the first or second target position and the detected moving amount on the image of the rear view from the vehicle, the second target position calculated by updating the first target position.

Vehicle backward movement assist device and vehicle parking assist device

A deceleration control apparatus for a vehicle including a controller that performs deceleration control based on a first target deceleration set based on a distance to a starting point of an upcoming curve, when the deceleration control for the curve is started at a position distant from the starting point of the curve; and that performs the deceleration control based on a second target deceleration set based on a lateral acceleration that is estimated to be detected when the vehicle passes the starting point of the curve, when the deceleration control for the curve is started at a position close to the starting point of the curve With this apparatus, it is possible to perform the deceleration control that provides drive assist according to the intention of the driver and that enhances driving convenience for the driver
