The invention provides a gear control device for a pilotless automobile. The gear control device comprises a gear shifting device and a controller for controlling the gear shifting device. The gear shifting device comprises a gear shifting control module, an electronic hand brake switch control module and a gear unlocking key control module; the electronic hand brake switch control module comprises a wire control switch for making an electronic hand brake in an automatic mode and a mode switching device for controlling switching between a manual mode and the automatic mode; the wire control switch relieves the hand brake based on a first level signal received from the controller; the gear unlocking key control module comprises a gear unlocking key and a first relay; and the first relay simulates the gear unlocking key to be pressed down or released based on a second level control signal received from the controller. According to the gear control device and method for the pilotless automobile, the requirement of a pilotless test can be met through the single gear shifting device, a more complete gear control system is achieved, high expansibility and practicability are achieved, and the gear control device and method can be applied to different automobile types.
Description
technical field [0001] The invention relates to the technical field of unmanned vehicle design, in particular to a gear position control device and method for an unmanned vehicle. Background technique [0002] At present, unmanned driving technology is developing rapidly all over the world. Domestic and foreign car companies and universities are actively exploring solutions for unmanned driving in various application fields. The exploration of unmanned driving technology is mainly based on ordinary cars. The unmanned driving platform built is to explore how to convert ordinary cars into unmanned vehicles. Among them, how to control the gear position is the focus of the modification. [0003] In the prior art, there are mainly two ways to refit the gear position control: add-on and refit. The retrofit type is to add an additional mechanical structure without changing the original gear structure, and realize the gear shifting of the driverless car through the control of the a...
