Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0008] To allow an understanding of the realization of the control module, FIG. 1 is attached, which illustrates the module diagram for controlling the acceleration signal object of this patent.

DESCRIPTION OF THE INVENTION

[0009] This invention refers to the electronic engineering field and describes a module for controlling the accelerating signal for cars, motorcycles, trucks and any vehicle with an electronic accelerating system, between the accelerator and the electronic control unit, that changes the signal sent by the accelerator reducing the response time of the actuators of the vehicle so that the vehicle responds the accelerations in a faster way, such being integrated with a wireless communication system via a compatible app and a customized and preferably luminous selector button.

[0010] Said customized luminous button, having an inner electronic circuit with a micro controller responsible for processing the information received in the control module and the information sent when it is pressed down and a RGB LED responsible for illumination with distinct colours for each different function mode chosen.

Electronic Circuit

[0011] The object described in this patent has an electronic circuit capable of reading the vehicle's electrical signals, whether analogue or digital, and adjusting a gain amplifying these signals according to the desired performance level.

[0012] The micro controller (3) of the circuit receives the signals sent by the accelerator (1), applies the required algorithm functions, thus whenever the accelerator is pressed down the signal with an applied gain is sent to the buffer (4), that makes current corrections in the signals and sends to the electronic control unit (6) that, on its turn, turns on the actuators and peripheral sensors.

[0013] The circuit has a redundancy system that allows, in case of failure or disconnection of the module described in this patent, to ensure that the original signal generated by the vehicle's accelerator continues to be sent to the electronic center without harming the vehicle's driving. This is because the micro controller (3) reads the output signals of the buffer (4) and in if the signals of such reading are different than expected, the circuit causes the switch (2) to close down the original signal, sending the original signal of the vehicle to the electronic control unit without impairing the driving.

[0014] The electronic circuit of the module described in this patent has communication with a luminous selector button (5), through the pair of wires making simultaneously the function of supplying the electronic circuit of the button and electric supply thereof. The button has a micro controller and RGB LEDs responsible for showing in different colours each function mode selected in the module object described in this patent.

[0015] The circuit has communication with the CAN network of the vehicle, this enabling the module system to identify when the reverse gear is actuated, turning off the signal amplification or reducing to a lower signal, enabling the vehicle not to react in a sudden way during maneuvering moments.

Luminous Selection Button

[0016] The electronic circuit of the button has a micro controller and RGB LEDs, which change the colour according to the function selected by the button or app.

App

[0017] The object described in this patent connects to smartphones, tablets, computers, and the like through a wireless network (wireless), that can be via Bluetooth, Wi-Fi, radio, infrared communication and any other type of wireless remote communication. The communication is closed and has data integrity verification and cryptography. This app enables the user to have access to all the functionalities of the object described in this patent.

[0018] Through the app the user may gain access to select the functions of: original mode, performance gain or level, adjustments of the performance stages, ECO mode for reducing the acceleration, accelerator block, valet mode, mode adjustment, intensity of the button colours, safety adjustments, recovery of the Bluetooth password, reduction of the accelerator signal, automatic pilot, speed limit, night-time function for automatic change of the light and intensity of the button colours, key of presence and gain graphics.

[0019] The control module contains a failure diagnosis mode to diagnose if the signal received is the same signal expected and if it happens when reading the input signals being the same compared with a standard value of each model. in case the signal received is within the standards, the control module applies the functions, if they are non-compliant with the control module it makes a “bypass” of the original signal of the vehicle and emits an alert on the luminous button leaving the illumination in a red colour intermittent with a white one, it can contain a “beep” or audio signal of alert.

[0020] The app allows the change of gain percentages for each stage, wherein the user can select a value from 0 to 100% and even if the last chosen value is stored in the non-volatile memory so the user of the device can make a setup that will remain active until another adjustment is made, both by the button and by the app, prevailing the one that does it last.

[0021] The original mode consists of the function of making a keying of the output signal of the accelerator, thus causing the output signal of the accelerator to be the same signal sent to the voltage control unit.

[0022] The performance gain mode has five distinct stages, stage “0” being the original one, stage “1” dynamic, stage “2” sport, stage “3” super sport and stage “4” race.

[0023] At the original “0” stage, the conditions of the output signal of the accelerator are the same as the signals sent to the electronic control unit, through keying of the input signal to the output.

[0024] At the dynamic “1” stage, a gain proportional to 25% more of the input signal at the output is available for the electronic control unit.

[0025] At the sport “2” stage, a gain proportional to 50% more of the input signal at the output is available for the electronic control unit.

[0026] At the super sport “3” stage, a gain proportional to 75% more of the input signal at the output is available for the electronic control unit.

[0027] At the race “4” stage, a gain proportional to 100% more of the input signal at the output is available for the electronic control unit.

[0028] In the adjusting mode of the performance stages, we have the following adjustment ways: stage “1” dynamic will be adjusted between 15 and 25%, stage “2” sport will be adjusted between 30 and 50%, stage “3” super sport will be adjusted between 55 and 75″ and stage “4” race will be adjusted between 80 and 100%.

[0029] The ECO mode is a mode for reducing acceleration. The module reduces the accelerator signal sent to the electronic managing centre, thus reducing the accelerator answer. Thus when the driver presses the accelerator the module acts reducing sharp starts that wear the mechanical parts of the vehicle, providing a softer exit of the vehicle generating more comfort during driving.

[0030] At the mode of accelerator blockage, the function is to block the output signals of the accelerator, thus preventing the use thereof.

[0031] The valet mode has the function of limiting the speed of the vehicle, adjusting the proportionality of the accelerator signal between 15 and 45%; the adjustment range will be saved in the non-volatile memory of the control module herein described.

[0032] The adjustment way of the modes allows the change of the beginning and end of each gain stage, storing the adjustment values in the non-volatile memory of the control module.

[0033] The adjustment mode of the button illumination is aimed at adjusting the intensity of the light brightness of the button in an automatic way through the app, being more intense during the day and less intense at night, all the illumination adjustments will be saved in the non-volatile memory of the control module.

[0034] In the security setting mode, four different types of security settings are available: 1) unblocking by presence, 2) valet by attendance, 3) lock password, 4) valet password. The unblocking by presence setting comprises the function of deactivating the blocking function whenever the module is in connection with the app.

[0035] The operation at the unblocking by presence adjustment must follow the following criteria: it can be activated or turned off only by the app and when activated, in case the module is turned off and turned on again, the control module must leave the blocking and there will be a new connection.

[0036] The valet mode by presence when activated, after the module connects with the app, deactivates it.

[0037] At the safety adjustment mode, user is allowed to enable or disable the password request to enter lock mode via app and the user is allowed to enable or disable the password request for entering the valet mode via app.

[0038] In Bluetooth password recovery mode, user is allowed to recover original Bluetooth password, in the following way: pressing the button for a time equal or higher than 30 seconds, after such time the illumination of the button must be in the magenta colour, the button should no longer respond to the press until a connection occurs followed by a disconnection via Bluetooth or the module is restarted; the module being in this mode, must allow the user to connect to the unit without needing the password pairing; the module shall enter in the remote programming mode enabling the receipt of AT commands via Bluetooth.

[0039] In cruise control mode, speed control is achieved in two ways, the first one being through the GPS speed that is obtained by interpreting the device hardware wherein the app is installed and the second way is through the CAN network of the vehicle itself and also the possibility for the user to define a constant maximum speed at which the vehicle will remain while the function is activated; once selected the maximum limit speed, the control module will not allow the driver to surpass the established speed, even if the driver tries to accelerate more.

[0040] At the accelerating graphics mode, the function shows in a graphic way in the compatible app the relation between the original signal and the signal generated by the control module, updating the graphic every 100 milliseconds.
