In the manufacture of a panel body composed of a first panel, which has a structure in which two panel materials of different sheet thicknesses are butted and joined, and a second panel, which is arranged on the outside of the first panel and connected thereto by hemming, the first panel is pressed so that the main surfaces of the two panel materials on the joined portion side form a single plane, and a sloped portion due to the difference in sheet thickness appears on the rear side thereof, the main surface of the first panel on the joined portion side is arranged on the second panel side, and hemming of the second panel is performed against the edge portion of the first panel that includes the sloped portion, thereby achieving good interior and exterior appearance quality of the panel body.

Steering control device for vehicle and steering control method for vehicle

A driving assistance device improves the accuracy of driving assistance for parking. A traveling controller detects a line positioned on a road surface from a captured image captured by a camera. A parking frame is extracted from the detected line and acceleration suppression control of a vehicle is executed based on the extracted parking frame. At this time, the acceleration suppression control is cancelled if a crossing is detected based on the captured image.

Driving assistance device

A vehicular acceleration suppression device reduces the degradation in the drive performance due to the acceleration suppression control activated outside the parking region. A parking frame line candidate which is a candidate of a parking frame line is extracted from a bird's-eye view image acquired by performing a bird's-eye view conversion on a captured image around a vehicle, and a parking frame line candidate corresponding line corresponding the parking frame line candidate is extracted from the captured image of the front of the vehicle. Then, the parking frame line candidate corresponding to the parking frame line candidate corresponding line length of which is longer than a parking frame line length threshold is eliminated from the candidate to be detected as the parking frame.

Vehicular acceleration suppression device

A vehicle acceleration suppression device and a vehicle acceleration suppression method are provided to be capable of suppressing a degradation in a drive performance and suppressing acceleration at the time of an incorrect manipulation of an accelerator, at the time of parking. Based on a parking frame certainty degree indicative of a degree of certainty that there is a parking frame in a vehicle travel direction and a parking frame entering certainty degree indicative of a degree of certainty that the vehicle enters the parking frame, a total certainty degree indicative of a total degree of certainty of the parking frame certainty degree and the parking frame entering certainty degree is set. As the total certainty degree is higher, a suppression degree of the vehicle acceleration to be controlled in response to a manipulation amount of an accelerator pedal manipulated by a driver to instruct a drive force is increased.

Vehicle acceleration suppression device and vehicle acceleration suppression method

An acceleration suppression device for a vehicle and an acceleration suppression method for a vehicle can reduce a reduction in drivability due to the operation of an acceleration suppression control while crossing an intersection. If it is determined that an intersection lying ahead of an own vehicle is detected, a process is implemented to suppress an acceleration suppression control in a travel distance range in which the travel distance of the own vehicle after detecting the intersection is less than or equal to a preset first travel distance threshold value.

Acceleration suppression device for vehicle, and acceleration suppression method for vehicle

A total certainty factor indicating a total degree of certainty of the parking frame certainty degree and the parking frame entering certainty degree is calculated based on a parking frame certainty degree indicating the degree of certainty that a parking frame is present in a travel direction of a vehicle, and a parking frame entering certainty degree indicating the degree of certainty that the vehicle enters the parking frame. When the total certainty factor is low, acceleration of the vehicle controlled according to an operation amount of an accelerator pedal for instructing a driving force by operation of a driver is suppressed with a low suppression degree, as compared with a case where the total certainty factor is high. Further, the acceleration of the vehicle is suppressed at a low suppression degree according to the travel direction of the vehicle.

Based on a parking frame certainty degree indicative of a degree of certainty about a presence is a parking frame in the travel direction of the vehicle and a parking frame entering certainty degree indicative of a degree of certainty about whether the vehicle enters the parking frame, a total certainty degree indicative of a total degree of the certainty of the parking frame certainty degree and the parking frame entering certainty degree is calculated. Acceleration of the vehicle is controlled depending on a manipulation amount of an accelerator pedal manipulated by a drive to instruct a driving force and is suppressed in a lower suppression degree when the total certainty degree is lower than when the total certainty degree is higher. Furthermore, the acceleration of the vehicle is suppressed in the suppression degree decreased depending on the travel direction of the vehicle.

A total certainty factor indicating a total degree of certainty of the parking frame certainty degree and the parking frame entering certainty degree is calculated based on a parking frame certainty degree indicating the degree of certainty that a parking frame is present in a travel direction of a vehicle, and a parking frame entering certainty degree indicating the degree of certainty that the vehicle enters the parking frame. When the total certainty factor is low, acceleration of the vehicle controlled according to an operation amount of an accelerator pedal for instructing a driving force by operation of a driver is suppressed with a low suppression degree, as compared with a case where the total certainty factor is high. Further, the acceleration of the vehicle is suppressed with a lower suppression degree as the vehicle speed of the vehicle is higher.

A three-dimensional object detection device is provided with an image capturing device, a three-dimensional object detection unit, a rainfall state detection unit, a three-dimensional object assessment unit and a controller. The image capturing device captures an area rearward of a vehicle. The three-dimensional object detection unit detects a three-dimensional object rearward of the vehicle and calculating a traveling speed of the three-dimensional object, based on images obtained by the image capturing device. The rainfall state detection unit detects a state of rainfall including cases of rainfall or formation of a water film on a road surface due to rainfall. The three-dimensional object assessment unit accesses the three-dimensional object to be another vehicle when the traveling speed of the detected three-dimensional object lies within a preset setting range. The controller changes the traveling speed setting range to be narrower when the rainfall state detection unit has detected a rainfall state.

Three-dimensional object detection device, three-dimensional object detection method

A solid object detection device detects solid objects in the periphery of a vehicle. A camera captures images including detection regions set in adjacent traffic lanes to the rear of the vehicle. A solid object assessment unit assesses whether or not a solid object is present in the detection regions. A lateral position detection unit detects a distance between the vehicle position and a dividing line that divides traffic lanes. A region setting unit enlarges the detection region on the side of the dividing line by a greater amount correspondingly with respect to an increase in the distance to the dividing line. A traffic lane change detection unit detects a traffic lane change made by the vehicle. Upon detecting a traffic lane change by the vehicle, a smaller enlarged amount is used when enlarging the size of the predetermined region outward in the vehicle-width direction.
