Abstract

The invention relates to an automobile acceleration pedal device with a tactile feedback function. The device comprises a pedal support, a pedal rotating shaft system, a control motor shaft system, a planetary gear mechanism and a control push rod mechanism, wherein the pedal rotating shaft system, the control motor shaft system, the planetary gear mechanism and the control push rod mechanism are installed on the pedal support. The pedal support is fixedly combined with bodywork of the automobile. The pedal rotating shaft system is composed of an angular displacement sensor, a pedal rotating shaft, an acceleration pedal and a reset spring. The control motor shaft system is mainly composed of a control motor and an output shaft. The planetary gear mechanism is mainly composed of a sun wheel, two planetary wheels, a planet support and a gear ring. The control push rod mechanism is mainly composed of a push rod, a fulcrum bar, a mandril, a buffer spring and a friction plate. According to the automobile acceleration pedal device with the tactile feedback function, free conversion of a common acceleration pedal mode and an active feedback type acceleration pedal mode can be achieved, and a driver can select the working modes according to individual needs.

Description

technical field [0001] The invention belongs to the technical field of automobile driving assistance systems, and in particular relates to an automobile accelerator pedal mechanical device with a tactile feedback function. Background technique [0002] The accelerator pedal is a part of the vehicle's fuel supply system. The driver controls the amount of air intake of the engine by controlling the amount of pedaling, thereby controlling the speed of the engine. The traditional cable-type accelerator pedal is directly mechanically connected to the engine throttle through the accelerator cable. With the development of automotive electronic technology, electronic accelerator pedals are now widely used in automobiles. Compared with the traditional cable accelerator pedal, the electronic accelerator pedal adds an angular displacement sensor instead of an accelerator cable. The angular displacement sensor is mechanically connected with the accelerator pedal coaxially, and its sig...
