Technical field

The present invention relates to an accelerator pedal controller for automobiles, in particular a safety accelerator controller, which can detect abnormally rapid re-depression of the accelerator pedal, activate a buzzer to warn driving, and feed back to the engine control unit at the same time. Reduce the amount of fuel to slow down the car.

Background technique

Vehicle rush usually refers to the unintentional acceleration behavior that occurs when the car is at a standstill and ready to start. Because the vehicle rush is not the state expected by the driver, it often becomes the cause of traffic accidents.

technical problem

The most common cause of vehicle rushing is improper operation by the driver, because the accelerator pedal and the brake pedal of a general vehicle are usually set next to each other to facilitate the driver’s manipulation. When the driver is a little careless or nervous In the state, it is very possible to accidentally step on the accelerator pedal when you want to brake, resulting in a violent accident.

At present, the original equipment of the car does not have a warning and protection device that can be used when the accelerator pedal is stepped on rapidly.

The safety accelerator controller of the present invention includes: a control unit including a microprocessor, a first variable resistor, and a buzzer, and the control unit is respectively associated with an automobile engine control unit and an accelerator pedal detector Electrically connected, when the accelerator pedal is rapidly moved under pressure, the accelerator pedal detector sends a signal to the control unit to activate the buzzer, and then the control unit converts the signal and transmits it to the engine control unit, The engine control unit reduces the fuel injection volume, slows down the car and turns off the buzzer.

Wherein, the control unit further has at least one connecting groove, and the control unit is accommodated in a housing, and the housing has a through hole corresponding to the connecting groove.

Wherein, the connection groove provides a detachable connection to a transmission line, the transmission line includes a first joint, a second joint and a third joint, the first joint is combined with the connection groove, and the second joint is connected to the accelerator pedal The detector is combined, and the third joint is combined with the engine control unit.

Wherein, the accelerator pedal detector has a second variable resistor inside, and the second variable resistor operates synchronously with the first variable resistor, and the first variable resistor sends a signal to the microprocessor.

Wherein, the microprocessor converts the signal and transmits it to the engine control unit, and the engine control unit reduces the fuel injection amount, so that the automobile decelerates to an idle state and turns off the buzzer.

Here, the rapidity is less than or equal to 1 second.

Wherein, the control unit further includes a sensitivity adjuster, so as to adjust the detection sensitivity of the control unit.

Beneficial effect

The beneficial effects of the present invention are:

Through the cooperation of the control unit, the microprocessor, the first variable resistor and a buzzer, it can warn and automatically reduce the fuel injection when the accelerator pedal is stepped on rapidly, so as to avoid the problem of rushing.

The installation process of the safety accelerator controller of the present invention is very simple, as long as the joint of the accelerator pedal detector on the automobile is unplugged, and the second joint and the third joint of the safety accelerator controller of the present invention are respectively connected.

The best mode of the present invention

The following describes the technical solutions in the embodiments of the present invention clearly and completely in conjunction with the drawings in the embodiments of the present invention. In the following description, many specific details are explained in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do so without departing from the connotation of the present invention. Similar promotion, therefore, the present invention is not limited by the specific embodiments disclosed below.

Please refer to FIG. 1 to FIG. 2, the safety throttle controller 1 of the present invention includes: a control unit 10 including a microprocessor 11, a first variable resistor 12 and a buzzer 13.

The resistor 12 is connected to control the second variable resistor 31 through the SPI protocol, and the microprocessor 11 outputs the high and low level to control the buzzer 13 through the IO port.

When the accelerator pedal abruptly (the abrupt speed is less than or equal to 1 second pressing the accelerator pedal quickly) moves to the bottom dead center under pressure, the second variable resistor 31 of the accelerator pedal detector 30 sends a signal to the control unit 10. Make the second variable resistor 31 and the first variable resistor 12 operate synchronously, and then the first variable resistor 12 sends a signal to the microprocessor 11, and at the same time the buzzer 13 is activated to warn When driving the accelerator pedal state, the control unit 10 converts the signal and transmits it to the engine control unit 40, and the engine control unit 40 reduces the fuel injection volume, so that the vehicle decelerates to an idle speed and then turns off the buzzer 13.

In addition, when the driver actively decelerates and resets the accelerator pedal, the control unit 10 automatically deactivates the buzzer 13 and stops sending signals to the engine control unit 40 to restore the control unit 10 to a normal working state.
