Abstract

The invention discloses an automatic driving test vehicle and a remote control system and method thereof. The automatic driving test vehicle comprises a housing, a power chassis connected to the bottom of the housing, and vehicle environment sensing equipment, wherein the vehicle environment sensing equipment comprises a positioning device, a video acquisition device, an environment sensing device, a bus controller and a vehicle processor; the system comprises the automatic driving test vehicle, a communication base station, a remote control center and a driving simulator; the remote control center receives the running data of the test vehicle, the relative position information of the test vehicle and the vehicle under test, and the running status data of the vehicle under test, performs multifaceted fusion and targeted processing on the received data to achieve the monitoring that whether the running data of the test vehicle is normal, receives the status data that the user manually operates the driving simulator uploaded by the driving simulator or receives the driving track data input by the user, analyzes the data to generate a control instruction, and sends the control instruction to the automatic test vehicle through via the communication base station.

Description

technical field [0001] The present disclosure relates to the technical field of test vehicles, and features an automatic driving test vehicle for behavior testing of unmanned vehicles, and a remote control system and method thereof. Background technique [0002] With the continuous deepening of research on the automation, intelligence and networking of autonomous vehicles, more and more companies have begun to make breakthroughs in this field, and the testing of autonomous vehicles has become a must for many developers. An issue that is not considered. However, in China, due to the lack of relevant laws, self-driving cars are not yet allowed to be tested on public roads, so companies that have the need for self-driving car testing may choose places that have opened road tests in the United States, Germany, and Japan. To test, either can only be achieved through domestic demonstration areas. Therefore, in the past two years, a large number of intelligent network connection ...
