Abstract

The invention provides an automated automobile driving device. The automated automobile driving device comprises a gear shift manipulator, a gear shift manipulator control module, an accelerator pedal mechanical leg, a braking pedal mechanical leg, a clutch pedal mechanical leg, a mechanical leg control module, an automobile speed detection module, an engine rotation speed detection module and a vehicle-mounted computer control system. The automated automobile driving device can adapt to various models of automobiles and is simple in structure and small in size, the normal driving space for a driver is not occupied, the automated automobile driving risk and the automobile experiment risk are reduced, and the automobile experiment transfer and transportation cost is reduced; high-precision servo motors and high-precision motor state sensors are adopted for driving motors of the mechanical legs and the gear shift manipulator, the driving motors are in real-time communication with the vehicle-mounted computer control system, and thus control precision and stability are improved; a spatial parallel-connection four-bar mechanism forms a gear shift device of the gear shift manipulator, multiple degrees of freedom in space are achieved, and high-efficiency gear shift operation can be performed on a gearbox.

Description

technical field [0001] The invention relates to the technical field of automobile automatic driving devices and test vehicles, in particular to a mechanical device for coordinatingly controlling automobile clutch pedals, brake pedals, accelerator pedals and gearbox shifting devices, which can replace human drivers to complete automobile automatic driving work . Background technique [0002] The automatic driving device of the car can automatically control the clutch pedal, brake pedal, accelerator pedal and gearbox shifting mechanism of the car without modifying the structure of the car when the car is driving automatically or for testing. In the research of unmanned vehicles, the automatic driving device of the vehicle must be able to complete the command action issued by the control system of the unmanned vehicle, and control the vehicle to drive automatically; it must be able to adapt to different vehicle platforms and complete the automatic driving operation of different...
