Abstract

The present invention relates to a foldable pedal device for a vehicle. In a manual driving mode where the driver is driving directly, the accelerator pedal assembly (100) and the brake pedal assembly (200) are rotated backward from the vehicle body panel (10) and popped up to be exposed toward the driver. In an autonomous driving mode where the driver is not driving directly, the accelerator pedal assembly (100) and the brake pedal assembly (200) are rotated forward and inserted into the panel groove (11) of the vehicle body panel (10), thereby becoming a hidden state where exposure toward the driver is blocked. The amount of popping up of the accelerator pedal assembly (100) and the brake pedal assembly (200) can be increased without a rail structure, so that when switching from autonomous driving mode to manual driving mode, the driver can operate the accelerator pedal assembly (100) and the brake pedal assembly (200) more easily and conveniently.

Description

Foldable Pedal Apparatus for Vehicle The present invention relates to a foldable pedal device for a vehicle, and more specifically, to a technology for a foldable pedal device for a vehicle in which, in a manual driving mode where the driver directly drives, the pedal pad protrudes from the pedal housing and is exposed toward the driver so that operation by the driver is possible, and in an autonomous driving situation, the pedal pad is inserted into the pedal housing so that operation by the driver is impossible and exposure toward the driver is blocked. Autonomous vehicles are smart vehicles equipped with autonomous driving technology that allows them to find their way to a destination on their own without the driver directly operating the steering wheel, accelerator, or brakes, and their development has been progressing rapidly recently. When autonomous driving becomes a common reality, drivers can select a manual driving mode in which they drive directly, and an autonomous driving mode in which the vehicle drives itself to the destination without the driver driving directly. In autonomous driving mode, the driver needs to be able to stretch their legs and rest comfortably, so if the pedals (accelerator pedal, brake pedal) located in the lower space of the driver's seat remain exposed inside the cabin, it has the disadvantage of interfering with the driver's rest. In addition, an autonomous driving situation is one in which the driver does not operate the vehicle's pedals (accelerator pedal, brake pedal). If the driver operates the pedals during autonomous driving, the vehicle controller determines that the driver wishes to terminate autonomous driving and take over driving, and terminates the control for autonomous driving. However, since the vehicle's pedals are installed to be exposed in the space under the driver's seat, there is a risk that the driver may unconsciously operate the pedals during autonomous driving (situations of pedal misoperation), and in such cases, there is a risk of accidents occurring depending on road conditions or the distance between vehicles. Therefore, it is necessary to develop technology for a pedal device that exposes the pedal pad so that it protrudes toward the driver to enable operation in manual driving mode, and blocks the exposure of the pedal pad to prevent operation by the driver in autonomous driving situations to ensure safety, such as comfortable rest and prevention of erroneous operation. The matters described above as background technology are intended only to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art.
