Problems solved by technology

[0003] However, since the previously described conventional axial control device adjusts the optical axis of the headlights only after the motor vehicle is tilted, an impact on the headlights is generated at a position when the motor vehicle is running on a road and the gradient of the road changes. The delay in adjusting the optical axis, and considering the road surface, it is difficult to quickly adjust the optical axis of the headlight to the optimal axis

Embodiment approach

[0105] For example, the control section 10 instructs one axial adjustment actuator 22 to adjust each of the image pickup axis of the vehicle-mounted camera 21 and the optical axis of the headlight 23 to an optimum direction. However, the concept of the present invention is not limited thereto. For example, the axial control device 1 may have a plurality of axial adjustment actuators 22, so that the axial adjustment actuators 22 respectively adjust the axial direction of the corresponding device.

[0106] Further, in the previously described exemplary embodiment, the control section 10 determines that the completion point A is equivalent to 1 The road slope change point A 0 . However, the concept of the present invention is not limited thereto. For example, the control unit 10 may determine 1 The road slope change point A 0 .

[0107] When the control section 10 adjusts the optical axis of the headlights 23, the delay in the adjustment of the optical axis of each headligh...

Abstract

An axial direction control device obtains information regarding a road gradient in front of a road on which a motor vehicle drives. The axial direction control device adjusts an optical axis of headlamps and an image acquiring axis of an in-vehicle camera to an optimum direction on the basis of the acquired information before the motor vehicle has reached a road gradient change point. The road gradient is changed at the road gradient change point. Because the axial direction control device quickly changes the axial direction of each of the headlamps and the camera to an optimum direction before the road gradient is changed, driver safety and comfort is enhanced.

Description

technical field [0001] The present invention relates to an axial control device and a program that perform axial control capable of adjusting the direction of devices such as an image pickup axis of an on-vehicle camera mounted on a motor vehicle and an optical axis of a headlight, and a program. Background technique [0002] There are axial control devices, for example, Japanese Patent Laid-Open Publication No. JP 2008-247210 discloses a technique of adjusting the optical axis of a headlight of a motor vehicle based on the amount of inclination of the motor vehicle. [0003] However, since the previously described conventional axial control device adjusts the optical axis of the headlights only after the motor vehicle is tilted, an impact on the headlights is generated at a position when the motor vehicle is running on a road and the gradient of the road changes. The delay in the adjustment of the optical axis, and considering the road surface, it is difficult to quickly ad...
