Drive-by-wire chassis used in field of unmanned driving

Abstract

The embodiment of the invention discloses a drive-by-wire chassis used in the field of unmanned driving. The drive-by-wire chassis comprises a vehicle body frame system, a wheel system, a suspension system, a driving system, a steering system and a control circuit system. The drive-by-wire chassis is small in overall size, complete in performances, low in cost, capable of being produced in batch and easy to universalize; standardization and universalization of a communication protocol and a hardware interface are easy to realize; the driving system and the steering system are directly controlled through a vehicle control unit, and instructions sent by a decision-making system can be directly received; the drive-by-wire chassis has the characteristics of universalization and platformization, and various mechanical devices can be additionally arranged on the drive-by-wire chassis to achieve various purposes such as sweeping and transporting; and the whole chassis is completely packaged,the upper portion of the chassis is completely blank, and various sensors and mechanical devices can be installed to make the chassis used for various commercial vehicles including express delivery, sweeping, inspection and the like.

Description

Technical field [0001] The embodiment of the present invention relates to the field of unmanned driving technology, in particular to a wire-controlled chassis used in the field of unmanned driving. Background technique [0002] At present, the market demand for all kinds of small unmanned vehicles is increasing day by day, and there are more and more unmanned projects in factories, residential areas, and industrial parks. However, most of the current driverless companies choose traditional commercial vehicles, sightseeing cars, etc. as their carrier chassis, or customized commercial vehicles and modified commercial vehicles as their carrier chassis. The main disadvantages of this approach are: (1) Traditional chassis (existing commercial vehicles) are mostly designed for manned driving. In addition to the drive system, the steering and suspension systems are completely mechanically connected, making it difficult to carry out wire-controlled transformations. It cannot directly su...

Problems solved by technology

[0003] For this reason, the embodiment of the present invention provides a control-by-wire chassis used in the field of unmanned driving to solve the problem that traditional chassis in the field of unmanned driving are difficult to carry out transformation by wire, and cannot directly supply power to the perception system of unmanned vehicles. It is also impossible to receive the instructions issued by the decision-making system, and customizing commercial vehicles and modifying commercial vehicles as the carrier chassis is difficult to modify, poor adaptability, non-universal, high cost, communication protocols, hardware interfaces, etc. need to be re-customized, the cycle is long, and it is difficult to mass produce The problem
