Anti-interference device of magnetic magnet induction type acceleration pedal

Abstract

The invention relates to an electronic accelerator pedal, in particular to an anti-interference device of a magnetic sensing accelerator pedal. The technical proposal of the invention is that a protection output terminal of a power supply protection circuit is connected with a signal collection and output circuit; when the environment supplies electricity for the signal collection and output circuit, the power supply protection circuit provides protection for the signal collection and output circuit; when the accelerator pedal is trampled, the signal collection and output circuit converts the deflection quantity of the angle of the accelerator pedal into the electromagnetic signal and converts the collected magnetic signal into the electric signal at the same time which is sent to an engine accelerograph controller. The invention can improve the safety, sensitiveness and driving comfort, reduces the oil consumption, reduces the exhaust pollution, and meets the environmental requirement much better.

Description

technical field [0001] The invention relates to an electronic accelerator pedal, in particular to an anti-jamming device for a magnetic induction accelerator pedal. Background technique [0002] Manipulating the opening of the throttle can control the flow of the combustible mixture, change the speed and power of the engine to meet the needs of the car. [0003] The traditional engine throttle control mechanism works by connecting one end of a stay wire (soft steel wire) or a pull rod to an accelerator pedal (accelerator pedal), and the other end to a throttle linkage plate. This way of working can only control the opening of the throttle valve by stepping on the depth of the accelerator pedal. It is difficult to adjust the opening angle of the throttle valve to the theoretical air-fuel ratio state, and the fuel cannot be fully burned. Its transmission ratio is 1:1, that is to say, how much we pedal, the throttle opening angle is the same, but in many cases, the throttle va...

Problems solved by technology

This way of working can only control the opening of the throttle by stepping on the depth of the accelerator pedal. It is difficult to adjust the opening angle of the throttle to reach the state of the theoretical air-fuel ratio, and the fuel cannot be fully burned.

Its transmission ratio is 1:1, that is to say, how much we pedal, the throttle opening angle is the same, but in many cases, the throttle valve should not open such a large angle, so the throttle valve is opened at this time The angle is not necessarily the most scientific. Although this method is very direct, its control accuracy is very poor

When the throttle valve is opened suddenly, it is the maximum load state of the engine at this time. The full load will cause insufficient combustion of the engine. At the same time, the fuel injector will also increase the fuel injection, resulting in waste of fuel. The load on the engine increases, which shortens the use of the engine. Life expectancy, not conducive to environmental protection, etc.
