Description

Accelerator pedal for vehicle with improved foot feel

technical field

The utility model relates to the technical field of auto parts, in particular to an accelerator pedal for a vehicle that improves foot feeling.

Background technique

The accelerator pedal is an important safety component of the car. The accelerator pedal enables the user to accelerate the rotation of the engine. The user applies force to the pedal to increase the rotational speed of the engine and releases the accelerator pedal to decrease the rotational speed of the engine. The accelerator pedal is connected to the throttle valve by a cable and connecting rod. When the user depresses the accelerator pedal, the throttle valve will open to suck air into the cylinder, and the electronically controlled fuel injection device detects the amount of air and supplies gasoline suitable for the engine's operating state. Accelerator pedals are divided into mechanical accelerator pedals and electronic accelerator pedals. A mechanical accelerator pedal is a pedal type in which an accelerator pedal and a throttle valve of an engine are mechanically connected to each other by a cable. The electronic accelerator pedal is a pedal type in which a position of the pedal is sensed by a sensor module, and an operation of a throttle valve is controlled based on the sensed position signal. Mechanical accelerator pedals are prone to operational problems due to ambient conditions, temperature changes, cable aging, etc. Therefore, at present, the mechanical accelerator pedal has been replaced by the electronic accelerator pedal. Since the electronic accelerator pedal does not require cables, there is sufficient installation space, so driver fatigue can be reduced and fuel economy can be improved.

When the car is running, when it needs to accelerate quickly or quickly increase the driving force, in order to quickly obtain sufficient acceleration power, the driver needs to step on the accelerator pedal deeply to achieve rapid downshift acceleration. The foot feeling that triggers this rapid acceleration mode needs to make the user clearly perceive the change through the force drop caused by the sudden increase and decrease of the foot force. But this foot feeling still can't satisfy the user's higher use requirement.
