Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive brake pedal indicator device. Background Technology

[0002] In the automotive industry today, the anti-lock braking system (ABS) is commonly used in car braking. It maintains the vehicle's steering ability and shortens the braking distance by preventing the wheels from locking up during braking.

[0003] Of course, advanced driver assistance systems such as Pre-Collision Systems (PCS) have also been developed in the automotive industry. These systems use sensors such as cameras, radar, or lidar to monitor road conditions ahead and can issue warnings before a potential collision occurs, and even automatically activate emergency braking when necessary. Such active safety measures can significantly reduce the likelihood of accidents and protect the safety of passengers and other road users. However, the primary braking method is still the driver manually activating the anti-lock braking system (ABS) by operating the brake pedal.

[0004] However, in actual driving, especially on highways, drivers may keep their foot on the accelerator for a long time because they only need to maintain a certain speed and do not need to slow down. In this case, the driver may develop a muscle memory of a one-pedal mode. When emergency braking is required, the driver may not be able to quickly move their foot to the brake pedal, which may lead to accidental pressing or misoperation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automotive brake pedal indicator device, which solves the technical problem that drivers are prone to developing muscle memory for a single-pedal driving pattern.

[0006] An automotive brake pedal indicator device according to an embodiment of the present invention includes:

[0007] Membrane pressure switch: The membrane pressure switch is installed on the brake pedal of the vehicle;

[0008] Warning devices include a vibration motor and a warning light mounted on the steering wheel of the vehicle.

[0009] The membrane pressure switch, vibration motor, and indicator light are electrically connected to the vehicle's control system.

[0010] The technical principle of this utility model is as follows: when the driver does not move his foot to the brake pedal for a long time during driving, such as more than 30 minutes, the control system will illuminate the warning light.

[0011] If the driver moves their foot to the brake pedal at this time, simply moving it to the brake pedal without actually pressing it, the diaphragm pressure switch can sense the pressure from the foot. The diaphragm pressure switch then transmits the signal of the sensed pressure to the control system, which in turn turns off the warning light.

[0012] If the driver still does not move their foot to the brake pedal, the timer continues. When 1 hour has elapsed, the control system controls the vibration motor to vibrate and the indicator light to flash. The control system will only turn off the vibration motor and indicator light when the driver moves their foot to the brake pedal.

[0013] By providing prompts, drivers are encouraged to actively move their feet to the brake pedal at regular intervals, avoiding muscle memory. This allows them to react quickly and press the brake pedal in an emergency.

[0014] Compared with the prior art, the present invention has the following advantages: by using a membrane pressure switch set on the brake pedal in conjunction with an indicator light and a vibration motor set on the steering wheel, it solves the technical problem in the prior art that drivers are prone to developing muscle memory for a single-pedal driving mode.

[0015] Furthermore, the upper surface of the brake pedal is provided with a soft pad, the soft pad including a lower fixing layer and an upper protective layer stacked and fixed in sequence, the lower fixing layer is fixed on the brake pedal, the diaphragm pressure switch is disposed between the lower fixing layer and the upper protective layer, the lower fixing layer and the brake pedal are provided with a through hole, and the diaphragm pressure switch is connected to the control system by a wire passing through the through hole.

[0016] Furthermore, the steering wheel is equipped with a microcontroller, and the diaphragm pressure switch, vibration motor, and indicator light are electrically connected to the control system via the microcontroller.

[0017] It should be noted that the control system obtains the signal of whether the driver has placed his foot on the brake pedal through a membrane pressure switch to control the indicator light to turn on and off, as well as the vibration motor to turn on and off. This is a conventional technical means in the field and can be implemented with a microcontroller. This application does not involve any improvement to the algorithm.

[0018] Furthermore, the steering wheel includes a rim and a center portion, with spokes connecting the rim to both sides and the bottom of the center portion, the vibration motor being disposed within the spokes and rim at the bottom, and the indicator light being disposed on the inner side of the rim located on the upper side of the center portion.

[0019] Furthermore, the bottom of the wheel rim is provided with a groove, the bottom spokes are connected to the groove, the bottom spokes and the groove are provided with a common T-shaped cover plate, the T-shaped cover plate and the outer side of the wheel rim are provided with a common flexible layer, and the vibration motor is fixed on the T-shaped cover plate.

[0020] Furthermore, the T-shaped cover plate is hinged to the two parts of the spoke corresponding to the groove, and the T-shaped cover plate is fixed to the spoke at the end away from the rim.

[0021] Furthermore, annular metal wires are evenly distributed circumferentially between the rim and the flexible layer, and the metal wires passing through the groove are disposed between the T-shaped cover plate and the flexible layer.

[0022] Furthermore, the inner side of the wheel rim located on the upper side of the center is provided with an arc-shaped groove, and an indicator light is provided in the arc-shaped groove.

[0023] Furthermore, the microcontroller is located within the spokes at the bottom. Attached Figure Description

Detailed Implementation

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 The illustrated car brake pedal warning device includes a membrane pressure switch 101 and a warning device. The membrane pressure switch 101 is installed on the car's brake pedal 100, and the warning device includes a vibration motor 201 and a warning light 202 installed on the car's steering wheel 200. Specifically, the membrane pressure switch 101, the vibration motor 201, and the warning light 202 are wired to the car's control system 300.

[0031] like Figure 2 As shown, a soft pad 110 is provided on the upper surface of the brake pedal 100. The soft pad 110 includes a lower fixing layer 111 and an upper protective layer 112 that are stacked and fixed in sequence. The lower fixing layer 111 is fixed to the brake pedal 100 with adhesive. A membrane pressure switch 101 is disposed between the lower fixing layer 111 and the upper protective layer 112. The lower fixing layer 111 and the brake pedal 100 are provided with a through hole 120. The membrane pressure switch 101 is connected to the control system 300 by a wire 301 passing through the through hole 120, so that the signals of pressure and no pressure can be transmitted to the control system 300.

[0032] like Figure 3-4 As shown, a microcontroller 310 is installed inside the steering wheel 200. The diaphragm pressure switch 101, the vibration motor 201, and the indicator light 202 are electrically connected to the control system 300 through the microcontroller 310. That is, a microcontroller 310 is used to receive the signal from the diaphragm pressure switch 101 to determine whether to start the pre-timing or turn off the vibration motor 201 and the indicator light 202. After the timing reaches a certain time, the vibration motor 201 or the indicator light 202 is turned on, etc. Specifically, a microcontroller 310 of model such as ESP8266 or ESP32 can be used.

[0033] like Figure 1 , 3 As shown, the steering wheel 200 includes a rim 210 and a center portion 220. Spokes 230 are provided on both sides and at the bottom of the center portion 220 to connect to the rim 210. Specifically, the bottom of the rim 210 has a groove 211, and the bottom spokes 230 are connected to the groove 211. A common T-shaped cover plate 240 is provided on the bottom spokes 230 and the groove 211. A common flexible layer 212 is provided on the outside of the T-shaped cover plate 240 and the rim 210. The vibration motor 201 is fixed on the T-shaped cover plate 240, so that the vibration rod of the vibration motor 201 can be well transmitted to the rim 210 through the flexible layer 212. The microcontroller 310 is set in the bottom spokes 230.

[0034] like Figure 3 As shown, the T-shaped cover plate 240 is hinged to the two parts of the spoke 230 corresponding to the groove 211. The T-shaped cover plate 240 is fixed to the spoke 230 with screws at the end away from the rim 210, which facilitates the maintenance of the microcontroller 310 and the vibration motor 201.

[0035] like Figure 3 As shown, annular metal wires 213 are evenly distributed circumferentially between the rim 210 and the flexible layer 212. The metal wires 213 passing through the groove 211 are set between the T-shaped cover plate 240 and the flexible layer 212, making the vibration of the vibration motor 201 more noticeable on the rim 210.

[0036] It should be noted that the vibration motor 201 used in this application is a small vibration motor 201, and its vibration sensation is similar to that of a mobile phone vibration alert, which will not affect the driver's normal driving.

[0037] like Figure 3 As shown, the inner side of the wheel rim 210 located on the upper side of the center 220 is provided with an arc-shaped groove 214, and an indicator light 202 is provided in the arc-shaped groove 214. The indicator light 202 is set here so that the driver can see it without affecting the driver's normal driving.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
