Problems solved by technology

[0003] The control algorithm research of autonomous vehicles generally only controls the braking system, steering system, accelerator system and shifting system of the vehicle, but currently there is no gateway that only controls these four executive systems
The various automotive gateways available on the market are limited by this. At present, they are generally unable to be used for the complete bottom-level control and research of autonomous driving. Their convenience is greatly reduced, which is not conducive to reducing costs and has poor applicability.

Embodiment 1

[0040] The schematic diagram of the preferred connection structure of each module in the gateway in the present invention is as follows figure 1 shown, including:

[0041] 1) The controller is used to process the data of the vehicle bus. More precisely, it is connected with the vehicle bus to realize the information sending and receiving processing (including receiving and sending) with each system. More precisely, the controller is also used for Sending instructions according to priority, converting the format of input and output signals, broadcasting or shielding the output signal of the actuator control unit;

[0042] 2) A first CAN interface module, used to send and receive interactive data signals between the controller and the driving system; the controller is connected to the first CAN interface module. The first CAN interface module includes a braking system interface, a steering system interface, an accelerator system interface and a shifting system interface. The b...

Embodiment 2

[0083] An information processing method, the method is applicable to a gateway, the gateway runs on an automobile platform, and the method includes:

[0084] The driving system sends the first running information to the first gateway;

[0085] The first gateway sends the first exchange information to the second gateway according to the first operation information;

[0086] The second gateway sends the first control instruction according to the first communication information.

[0087] It should be understood that the traveling system also includes a braking system, a steering system, an accelerator system and a gear shifting system, and the first operating information includes accelerator controller feedback information (status information, diagnostic information, etc.), brake controller feedback information (status information, diagnostic information, etc.), shift controller feedback information (status information, diagnostic information, etc.), steering wheel information (...

Embodiment 3

[0097] An automobile, including the gateway of the basic solution in Embodiment 1.

[0098] The car also includes a central processing unit, and the central processing unit is signally connected to the first gateway and / or the second gateway;

[0099] Preferably, the central processing unit is signal-connected to the first gateway, and the central processing unit is not directly signal-connected to the second gateway;

[0100] More preferably, the central processing unit is connected to the first gateway signal via Ethernet or CAN;

[0101] Also more preferably, the central processing unit exchanges data with the second gateway through the first gateway.

[0102] Since the first gateway is connected to the driving system, the information and control commands in the driving system have relatively high priority, while the second gateway is connected to the comfort system, power system or information / entertainment system signal, the information and commands of these systems The...

Abstract

The invention discloses an information processing method and a gateway using the same. The method is suitable for the gateway, the gateway operates on an automobile platform; the method comprises the following steps that a first gateway transmits first class information to a driving system, and the first class information is used for controlling a driving system; and the driving system transmits second class information to the first gateway, and the second class information is used for feeding back a running system state. According to the method and the gateway, the first gateway and the driving system are used for mutually transmitting information, and independent controlling the braking, the steering, an accelerator and a gear shifting system under the driving system through the first gateway; and the method and the gateway can be used for automatic driving bottom layer control and research thereof, so that the cost is reduced, and the applicability is high.

Description

technical field [0001] The present invention relates to the technical field of network equipment, in particular to an information processing method and a gateway using the method, and in particular to a gateway for automatic driving vehicles. Background technique [0002] At present, almost all the actuators on the car need a control unit, and the vehicle gateway is responsible for coordinating all the actuators of the vehicle for coordination, including sending control commands to each control unit, assigning the action priority of each control unit, broadcasting or shielding control Unit output signal, etc. [0003] The control algorithm research of autonomous vehicles generally only controls the braking system, steering system, accelerator system and shifting system of the vehicle, but currently there is no gateway that only controls these four executive systems. The various automotive gateways available on the market are limited by this. At present, they are generally u...
