Hereinafter, the first and second terms are merely used for distinguishing and have no other meaning.
Fig. 1 is a schematic structural diagram of a vehicle-mounted human-computer interaction system according to an embodiment of the present invention. The vehicle-mounted human-computer interaction system 100 can be applied to an automatic driving vehicle. As shown in fig. 1, the vehicle-mounted human-computer interaction system includes 100: a vehicle control unit 110, a first display device 120, and a second display device 130. In the vehicle commissioning phase, the vehicle Control Unit 110 may be an industrial personal computer, and after the vehicle leaves the factory, the vehicle Control Unit 110 may be an Automatic Vehicle Control Unit (AVCU). The underlying Vehicle controller hereinafter may be an autonomous Vehicle controller (BVCU).
The vehicle control unit 110 is configured to receive the trip task information, and call an environment map file according to the trip task information to generate path planning data; wherein the path planning data comprises at least one piece of path information.
The travel task information may be sent to the vehicle control unit 110 by the server, or may be sent to the vehicle control unit 110 by the first display device 120.
When the travel task information is transmitted from the server to the vehicle control unit 110, the user may select a departure place, a destination, and a travel time on the first display device 120 through a terminal or the like. By way of example and not limitation, the terminal may be a smart device such as a mobile phone or a PAD, and an Application (APP) that communicates with the server is installed on the terminal.
The vehicle control unit 110 is specifically configured to receive the trip task information, and send map calling request information to the server according to the trip task information; wherein the map calling request information includes: a departure location and a destination; receiving an environment map file sent by a server; and generating path planning data according to the environment map file. The path planning data comprises a plurality of pieces of path information, the mileage of the plurality of pieces of path information is different, and the plurality of pieces of path information have priority levels according to different mileage. It is understood that each path information may have a priority label, for example, there are 3 alternative path information in total, and three alternative path information have identifiers, for example, 1, 2, and 3, to indicate the priority of 3 alternative paths, for example and without limitation, the mileage may be increased from 1 to 3.
Further, the travel task information may include a departure place and a destination, or may further include a travel time. The vehicle control unit 110 may perform path planning according to the travel time and the environment map file, and generate path planning data. For example, different routes are planned according to whether the travel time is in a peak period or not. According to the time period of the travel time, the multiple pieces of route information may have priorities, for example, the travel time is 9 am, there are 3 alternative routes, and according to the travel time, the three alternative routes have congestion degree identifiers, and according to the congestion degree from high to low, the congestion degrees of the 3 alternative routes may be represented by a, B, and C, by way of example and not limitation, and the congestion degree may be sequentially increased from a to C. When the travel task information is selected by the user on the first display device 120, the first display device 120 transmits the departure place and the destination input by the user to the vehicle control unit 110 to cause the vehicle control unit 110 to perform path planning.
The first end of the first display device 120 is connected to the vehicle control unit 110, and is configured to receive the route planning data and the route selection instruction of the user sent by the vehicle control unit 110, determine a current route according to at least one piece of route information and the route selection instruction, and send the current route to the vehicle control unit 110.
The first Display device 120 may be a Liquid Crystal Display (LCD).
Specifically, after the vehicle control unit 110 sends the route planning data to the first display device 120, the user determines the current route by inputting a route selection instruction. The path selection instruction may be generated by the user touching the first display device 120. By way of example and not limitation, the user may determine that path 1 is the current path by touching path 1 for a preset time from among path 1, path 2, and path 3.
The vehicle control unit 110 is further configured to receive the current path sent by the first display device 120, the vehicle operation mode selection instruction sent by the BVCU, and the environment sensing data sent by the sensing module, generate decision result information according to the current path, the vehicle operation mode selection instruction, and the environment sensing data, process the decision result information, and generate steering control information and torque control information; then according to the steering control information, generating steering prompt information, and according to the torque control information, generating target vehicle speed information; finally, according to the current path and the target speed information, generating estimated arrival time information of the vehicle; wherein the context awareness data comprises a current location of the vehicle and a current speed of the vehicle.
Specifically, the whole vehicle is provided with a control panel, and the control panel is provided with a power switch, an automatic driving switch, a transverse control switch and a longitudinal control switch. Where the lateral control switch controls the steering of the vehicle, when the lateral control switch is pressed, denoted as a first driving mode, the user is required to manually control the vehicle speed.

When in the first driving mode, only the steering control information is generated, when in the second driving mode, only the torque control information is generated, and when in the third driving mode, the torque control information and the steering control information are generated.
In order to prevent the transverse control switch and the longitudinal control switch from being pressed by mistake, an enabling switch can be further arranged, when the enabling switch and the transverse control switch are pressed simultaneously, the first driving mode is adopted, similarly, when the enabling switch and the longitudinal control switch are pressed simultaneously, the second driving mode is adopted, after the enabling switch and the transverse control switch are pressed, the transverse control switch is released, and the longitudinal control switch is pressed again, so that the third driving mode is adopted.
The whole vehicle is powered on by pressing a power switch, the vehicle control unit 110 and the BVCU perform self-checking after the power switch is powered on, and the vehicle control unit enters a standby mode after the self-checking is successful.
The BVCU is connected to the control panel through an Input/Output (IO) interface, and is configured to receive a vehicle operation mode selection instruction sent by the control panel, and send the vehicle operation mode selection instruction to the vehicle control unit 110 through a Controller Area Network (CAN) bus.
Specifically, the automatic driving mode is entered by pressing an automatic driving switch, and the vehicle mode selection command is generated by pressing a lateral control switch and/or a longitudinal control switch, and the vehicle mode selection command may be used to determine which automatic driving mode of the first to third driving modes the vehicle is in. The BVCU receives the ignition signal from the ignition system and then receives the vehicle mode selection signal from the control panel.
The vehicle control unit 110 and the server may communicate with each other by using a fourth generation communication system (4G) technology, a fifth generation communication system (5G) technology, a Wireless Fidelity (WI-FI) technology, or the like.
Next, the environmental sensing data of the above-mentioned sensing module will be specifically described.
