Vehicle driving mode control method, gateway and automobile

Abstract

The invention provides a vehicle driving mode control method, a gateway and an automobile. The control method comprises the following steps that a state flag bit of the gateway is obtained, whether the automobile is in an unmanned driving mode or a manned driving mode is judged according to the state flag bit, the gateway receives the vehicle equipment data and a control instruction output by an unmanned driving control module at the same time; if the automobile is in the manned driving mode, the vehicle equipment data are output; if the automobile is in the unmanned driving mode, the data frames in the vehicle equipment data are distinguished into relevant frames and irrelevant frames, a relevant domain in a relevant frame is replaced with a control instruction acquired from the unmanneddriving control module, the control instruction and the unrelated domain in the relevant frame are repackaged into a control frame to be output, and the data frame is a data unit of vehicle equipmentdata. According to the method, the problem that an existing manual driving vehicle is transformed in the prior art, so that the relatively changed cost is high, the period is long, the safety risk iscaused due to the fact that the relatively changed parts are not verified by a complete automobile part development process is solved.

Description

technical field [0001] The present invention relates to the field of vehicles, in particular to a control method for vehicle driving modes, a gateway and an automobile. Background technique [0002] In the unmanned driving project, the first problem is to let the machine drive the vehicle. People can turn the steering wheel to achieve steering, and use the brake pedal to achieve braking. However, the machine cannot drive the vehicle like a human, and can only use electrical signals. . [0003] Judging from the development of the autonomous driving industry, existing driverless vehicles have the following two characteristics: [0004] At the same time, it has two modes of unmanned driving and manned driving, mainly satisfying L3 or L4 unmanned driving applications. This level of unmanned driving cannot realize all-weather and full-scenario unmanned driving, and can only realize partial unmanned driving. Scenarios, even in an emergency, manual takeover is required. [0005]...

AI Technical Summary

Problems solved by technology

[0007] Based on the above problems, the present invention proposes a vehicle driving mode control method, a gateway and a vehicle, which solves the problem of high cost and long cycle caused by the transformation of existing manual driving vehicles by automatic driving companies in the prior art. The parts after the transformation have not been verified by the complete auto parts development process, and there may be design defects, which may cause technical problems of safety risks
