Embodiment Construction

[0020] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] At present, quite a few cars are still non-wire-controlled vehicles that cannot convert the driver's operation signal into an electrical control signal through sensors. These cars need a method to control them by wire, and they need to meet the technical safety requirements for non-autonomous driving vehicles to be refitted with automatic driving. The upgrade includes: 1. Wire control of non-wire-controlled cars; 2. Adding existing body sensors on the market, such as video and radar environmental data sensors to participate in driving decisions; 3. Obtaining driving information through road network management and service agencies With navigation decision information (such as acceleration, deceleration and steering, etc.), or on the contrary, the current vehicle's position coordinates, speed and acceleration information can a...

Abstract

The invention provides an automatic driving retrofit method and device suitable for a non-automatic driving vehicle. The automatic driving retrofit method is suitable for a drive-by-wire or non-drive-by-wire non-automatic driving vehicle driven by a battery or an internal combustion engine. The automatic driving retrofit device is connected with a refitted automobile, the automatic driving retrofit device is connected with a driving environment sensing unit and an automatic driving decision-making unit through a CAN bus, and the automatic driving decision-making unit firstly carries out automatic driving decision making according to driving environment sensing data obtained by the driving environment sensing unit. Then a motion control transfer function and a line control regulator in the automatic driving retrofit device are combined, steering, accelerator, brake and brake control signals and the like of the non-automatic driving vehicle are controlled by lines, and finally an automatic driving control signal is output to an ECU electronic control execution unit of the vehicle. According to the method, a universal method is found for automatic driving of the non-automatic driving vehicle, and line control of the non-automatic driving vehicle is rapidly and efficiently achieved.

Description

technical field [0001] The present invention relates to the field of automatic driving, in particular to an automatic driving refitting method suitable for non-autonomous driving vehicles, and to an automatic driving refitting device for realizing the automatic driving refitting method suitable for non-automatic driving vehicles. Background technique [0002] The standards and management policies and regulations for self-driving vehicles and roads in various countries are still being formulated, and self-driving technologies that meet L3 and above are already ready for commercial use. However, due to the long process of road network adapting to the transformation and development of autonomous driving, the regulatory policies of future autonomous driving in various countries are different, resulting in different processes and technical depths for vehicles and road networks to realize vehicle-road collaborative autonomous driving. Therefore, it is necessary to design a system t...
