Abstract

The invention discloses a hardware-in-the-loop simulation test system for a vehicle-mounted computing unit of an automatic driving vehicle, which can shorten the debugging and iteration time of a real vehicle vehicle-mounted computing unit and solve the problems of low efficiency and high consumption of direct real vehicle test. The simulation test system can test a real vehicle-mounted computing unit suitable for a structured road driving environment, simulate all hardware equipment in an automatic driving system including sensor hardware, the vehicle-mounted computing unit, a drive-by-wire system and the like, and provide a whole set of automatic driving test environment for developers; manual/automatic driving switching and actual application effect evaluation of the vehicle-mounted calculation unit can be realized, the response capability of the real vehicle-mounted calculation unit to various conditions can be comprehensively tested, the problems of the real vehicle-mounted calculation unit can be positioned, and the development time of a vehicle automatic driving system is saved; and the feasibility and the stability of a data transmission format and a communication mode used in a real vehicle automatic driving system can be tested.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a hardware-in-the-loop simulation test system for a vehicle-mounted computing unit of an automatic driving vehicle. Background technique [0002] With the rapid development of automatic driving technology, more and more vehicles begin to apply the automatic driving system. The present invention is aimed at the on-board computing unit of the automatic driving vehicle whose driving road environment is a structured road (such as urban traffic road). [0003] The on-board computing unit refers to a system that integrates a variety of automatic driving technologies, generally an industrial personal computer (IPC) or an embedded system, etc., which can be connected to various types of sensors required by the automatic driving technology and output control Instructions to control the driving of the vehicle are the "brain" in the automatic driving system. [0004] Today, with ...
