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.
