Description

Electronic Pedal Device of Vehicle

The present invention relates to a pedal device of a vehicle to operate electronically, and more particularly, to install a piezoelectric element pedal for the driver's foot at the position of the pedal and to install an infrared sensor for positioning the engine driving and braking of the vehicle, etc. The present invention relates to an electronic pedal apparatus of a vehicle for easily performing the same.

In general, in driving a vehicle, a driver drives a steering device by operating a steering wheel by hand, and the driver's foot operates an accelerator pedal to start and accelerate the vehicle, and a brake pedal ) Is designed to include a clutch pedal to decelerate and brake the vehicle and, in the case of a manual transmission vehicle, to control the engine power for the transmission gear shift.

The accelerator pedal 11, the brake pedal 12, the clutch pedal 13 is located below the driver's seat as shown in Figure 1, the conventional structure of each of these pedals as shown in Figure 4 It is configured to operate mechanically by the force of the foot.

However, the conventional pedal configuration as described above has a problem that the driver has to pressurize with a predetermined force in order to operate it, which is inconvenient and unnatural posture, resulting in instability of the driver's posture. There is a problem that increases the degree of injury by damaging the driver's body.

Accordingly, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide a more comfortable and natural driving by constructing a pedal of an electronic signal which is inconvenient for a driver to operate. It is to provide an electronic pedal device of a vehicle to reduce the injury of the driver even in an accident.

In order to achieve the above object, the present invention provides a piezoelectric element pedal unit (11, 12, 13) installed on the driver's seat (30) of the vehicle so as to perform the functions of acceleration, brake and clutch;

The position of the driver's foot on both sides of the piezoelectric element pedals 11, 12 and 13 and the position of the driver's foot on the upper side are detected positions of the piezoelectric element pedals 11, 12 and 13. Infrared sensors (1) (2) (3) (4) (5) installed to detect whether they are well placed; The brake device 16 and the throttle valve 17 of the vehicle receiving the detection signals of the piezoelectric element pedals 11, 12, 13 and the infrared sensors 1, 2, 3, 4, and 5. And an ECU 14 for controlling the clutch operation unit 18.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is an exemplary view showing the configuration of the present invention, the present invention is installed on the floor 30, each of the piezoelectric element pedal (11, 12, 13) that is responsible for acceleration, brake and clutch functions, the periphery In this case, a plurality of infrared sensors 1, 2, 3, 4, and 5 having respective functions are provided.

The infrared sensor (1) (2) (3) (4) (5) installed on both sides of the (1) (5) is installed to check the position of the driver's foot, the infrared sensor (2) installed on the remaining upper side (3) and (4) are installed to detect whether the position of the driver's foot is well positioned at the detection position of the piezoelectric element pedals 11, 12 and 13, respectively.

At this time, the infrared sensor (1) (2) (3) (4) (5) and the piezoelectric element pedal (11) (12) 13 is shown in Figure 3 is a block diagram according to the operation of the present invention The ECU 14 is configured to be connected to the ECU 14. The ECU 14 is configured to perform a respective operation including a warning light 15, a brake device 16, an engine throttle valve 17, and a clutch operating part 18. Will be.

Referring to the flowchart of Figure 4 the operation of the present invention configured as described above as follows.

First, each infrared sensor (1) (2) (3) (4) (5) is activated when the driver is close to the foot in the initialization state.If the foot is not properly positioned, these signals are inputted. The warning lamp 15 is operated by the ECU 14 and returns to the initial state when the warning lamp blinking frequency is three times or less.

In the operating situation of the infrared sensors (1) (2) (3) (4) (5), the driver presses the piezoelectric sensor pedals (11) (12) (13) so that each piezoelectric sensor is activated or accelerated. Each mission, etc. will perform normally. However, when each piezoelectric sensor is not operated, the warning lamp 15 is operated. When the number of blinking times of the warning lamp 15 is three or less, that is, if the driver corrects the position correctly, the warning lamp 15 returns to the initialization state of the piezoelectric sensor. Waiting for operation and performing the operation according to the corresponding operation of the brake device 11, the throttle valve 17 and the clutch operation unit 18.

The electronic pedal device of the present invention as described above has the effect of performing a more comfortable and natural driving by configuring a pedal of the mechanical configuration that is inconvenient for the driver to operate the electronic signal and each pedal in the event of a vehicle accident Preventing injury to the driver caused by the body has the effect of improving safety.
