Abstract

A foldable pedal apparatus for a vehicle includes pedal assemblies including pedal arms and pedal pads that are rotated rearwards and are thus popped up to a driver so as to be operated by the driver in a manual driving mode in which the driver directly drives a vehicle. Also, the pedal assemblies including the pedal arms and the pedal pads may be rotated forwards and upwards, so as to be located close to a front surface of a footrest panel and thus enter a hidden state in which exposure of the pedal assemblies to the driver is interrupted so as not to be operated by the driver in an autonomous driving situation.

First claim

What is claimed is:

1. A foldable pedal apparatus for a vehicle, comprising:
pedal assemblies configured to be rotated toward a front surface of a footrest panel to enter a hidden state, in which the pedal assemblies are nonmanipulable by a driver, in an autonomous driving situation, and configured to be rotated rearwards to enter a pop-up state, in which the pedal assemblies are exposed to the driver so as to be manipulable by the driver, in a manual driving mode; and
actuators fixed to the footrest panel, respectively connected to the pedal assemblies and operated to rotate the pedal assemblies forwards and upwards, or rearwards;
wherein each of the pedal assemblies comprises:
pedal arms connected to a corresponding one of the actuators and rotated during operation of the corresponding one of the actuators;
a pedal pad combined with the pedal arms and rectilinearly moved in a length direction of the pedal arms when external force is applied thereto; and
return springs installed with opposed ends supported by the pedal arms and the pedal pad so as to provide returning force to the pedal pad.

2. The foldable pedal apparatus according to claim 1 , further comprising two pedal devices, each pedal device comprising one of the pedal assemblies and one of the actuators, wherein the two pedal devices are installed on the footrest panel so as to be laterally spaced apart from each other.

3. The foldable pedal apparatus according to claim 2 , wherein one of the two pedal devices installed on the footrest panel so as to be laterally spaced apart from each other is used as an accelerator pedal device, and a remaining one of the two pedal devices is used as a brake pedal device.

4. The foldable pedal apparatus according to claim 1 , wherein for each of the pedal assemblies:
the pedal arms comprise two pedal arms laterally spaced apart from each other;
two connectors respectively combined with the two pedal arms are provided on the pedal pad;
connector holes configured to extend in the length direction are formed in the connectors; and
each of the return springs and one end of each of the pedal arms are inserted into a corresponding one of the connector holes.

5. The foldable pedal apparatus according to claim 4 , wherein for each of the pedal assemblies:
a pedal arm pin configured to protrude outwards is provided at a rear end of each of the pedal arms; and
a slot hole configured to extend in the length direction of the connectors is formed in each of the connectors so that the pedal arm pin is inserted into the slot hole.

6. The foldable pedal apparatus according to claim 4 , further comprising:
permanent magnets combined with ends of the connectors; and
pedal sensors combined with the pedal arms so as to face the permanent magnets,
wherein each of the pedal sensors detects a stroke change of a corresponding one of the pedal pads through a magnetic flux change depending on a position change of a corresponding one of the permanent magnets when the corresponding one of the pedal pads is rectilinearly moved.

7. The foldable pedal apparatus according to claim 6 , wherein each of the permanent magnets and each of the pedal sensors are provided at one of the two pedal arms and one of the two connectors of each of the pedal assemblies, or are respectively provided at both of the two pedal arms and both of the two connectors of each of the pedal assemblies.

8. The foldable pedal apparatus according to claim 6 , wherein the actuators are rotating motors fixedly installed on the front surface of the footrest panel, and
wherein the rotating motors are dual shaft motors configured to be rotatable in both a clockwise direction and a counterclockwise direction and provided with a motor shaft configured to protrude from opposed sides of each of the dual shaft motors.

9. The foldable pedal apparatus according to claim 8 , wherein the motor shaft configured to protrude from the opposed sides of each of the rotating motors is combined with front ends of the two pedal arms so that the two pedal arms are simultaneously rotated in the same direction when a corresponding one of the rotating motors is operated.

10. The foldable pedal apparatus according to claim 8 , further comprising:
printed circuit boards (PCBs) fixed to the footrest panel,
wherein each of the PCBs controls driving of a corresponding one of the rotating motors, receives a signal from a corresponding one of the pedal sensors, and generates a signal related to pedal functions.

11. The foldable pedal apparatus according to claim 10 , wherein, when a position of one of the permanent magnets is changed due to forward movement of a corresponding one of the pedal pads by driver operation in a situation in which the rotating motors are not operated in the pop-up state, in which the pedal pads are exposed to the driver due to rearward movement of the pedal arms by operating the rotating motors, a corresponding one of the PCBs generates the signal related to the pedal functions.

12. The foldable pedal apparatus according to claim 10 , further comprising protective covers fixed to the footrest panel and configured to cover the rotating motors and the PCBs so as to protect the rotating motors and the PCBs.

13. The foldable pedal apparatus according to claim 12 , wherein:
panel recesses configured to protrude forwards and to be open rearwards are formed on the front surface of the footrest panel;
the rotating motors and the PCBs are installed to be inserted into the panel recesses; and
the protective covers are installed at an interior side of a vehicle so as to shield the panel recesses while covering the rotating motors and the PCBs.

14. The foldable pedal apparatus according to claim 1 , wherein the pedal arms are formed in an L shape so that a supported state of the pedal arms through surface contact between the pedal arms and the front surface of the footrest panel is maintained when the pedal assemblies are rotated rearwards and are thus in the pop-up state.

15. The foldable pedal apparatus according to claim 1 , wherein:
the pedal pads comprise a pedal pad of a pedal assembly of an accelerator pedal device and a pedal pad of a pedal assembly of a brake pedal device;
the pedal pad of the pedal assembly of the accelerator pedal device has a greater size in a vertical direction than a size in the vertical direction of the pedal pad of the pedal assembly of the brake pedal device; and
the pedal pad of the pedal assembly of the brake pedal device has a greater size in a lateral direction than a size in the lateral direction of the pedal pad of the pedal assembly of the accelerator pedal device.

16. The foldable pedal apparatus according to claim 1 , wherein, when the pedal assemblies are in the hidden state, the pedal assemblies are shielded by a center fascia under cover so as not to be exposed to the driver.

17. The foldable pedal apparatus according to claim 16 , wherein, when the pedal assemblies in the hidden state are rotated rearwards and are thus converted into the pop-up state, the pedal assemblies protrude through a passage formed under the center fascia under cover so as to be exposed to the driver.
