An electronic pedal device at operates in a pressure operation manner and thus enables a driver to operate a pedal with a small force. It is possible to greatly change operation force of a pedal pad using an elastic material which is formed to be gradually increased in a spring constant although the operational displacement of the pedal is very small, enabling the driver to easily recognize the operation state of the pedal pad. The pedal device detects operation of the pedal through a dual detecting structure using a first pressure sensor and a second pressure sensor, further ensuring safety in response that operating the pedal.

Electronic pedal device

A power module and a manufacturing method includes a chip; an upper substrate provided above the chip and formed with a circuit pattern; a lower substrate provided below the chip and formed with a circuit pattern; and a spacer including a plurality of metal portions electrically connecting at least two among the chip, the upper substrate and the lower substrate to transmit an electrical signal, and an insulating portion positioned between the plurality of metal portions and insulating the metal portions.

Power module and manufacturing method thereof

An electronic pedal apparatus may be operated by a driver with a small force. When the driver operates a pedal pad, the pedal pad is operated with a fine displacement, but a change in a pedal force is increased through compression of a return spring using a rotation lever and a spring guide, so that the driver is capable of easily recognizing an operation situation of a pedal. Furthermore, safety during operation of the pedal may be more enhanced by using a dual sensing structure in which first and second permanent magnets and first and second printed circuit boards (PCBs) are used.

A foldable pedal device for vehicles enables an accelerator pedal module and a brake pedal module, which have different pop-up strokes, to be simultaneously popped up and hidden by operation of one actuator module and blocks introduction of moisture and foreign substances by shielding a gap between a footrest panel and the pedal module using a shield membrane.

Foldable pedal device for vehicles

An electronic pedal apparatus, in which a driver may operate the electronic pedal apparatus with a small effort, may operate by fine displacement when the driver operates a pedal pad, but a spring module is displaced by being pressed by the pedal pad and displaced by being pressed by a rotation lever so that a large change in pedal effort may be implemented, and safety during an operation of a pedal may be further improved by use of a dual detecting structure using first and second permanent magnets and first and second PCBs.
