Detailed Description
In order to make the above and other features and advantages of the present invention more apparent, the present invention is further described below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limiting, for those of ordinary skill in the art.
Fig. 1 shows a schematic diagram of an automatic driving assistance system for a vehicle according to an embodiment of the present invention.
As shown in fig. 1, the automatic driving assistance system 100 for a vehicle may include: the system comprises an electronic control unit 110, a manipulation gateway 120 and a central gateway 130, wherein one end of the manipulation gateway 120 is connected with the electronic control unit 110 to receive original driving control information sent by the electronic control unit. The other end of the steering gateway 120 is connected to the central gateway 130 to transmit a control signal for controlling the driving of the vehicle to the central gateway. The steering gateway 120 is configured to also receive activation instructions and updated travel control information.
The steering gateway 120 may initiate an activation mode upon receiving an activation instruction, and in the activation mode, the steering gateway 120 may reset original travel control information transmitted by the electronic control unit 110 to the updated travel control information so that travel of the vehicle is controlled according to the updated travel control information.
In one embodiment, the steering gateway 120 may be further configured to be capable of operating in an inactive mode in which the steering gateway 120 directly transmits the original driving control information transmitted from the electronic control unit 110 to the central gateway 130 so that the vehicle is controlled to travel according to the original driving control information. In the inactive mode, the steering gateway functions as a "transparent" gateway.
For example, assuming that the operating gateway does not receive the activation command, the operating gateway remains in the inactive mode, and the operating gateway 120 transmits the original driving control information to the central gateway 130 in the inactive mode. In this way, in the inactive mode, the manipulation of the gateway does not affect the normal running of the vehicle using the original running control information transmitted from the electronic control unit 110 as a control signal.
Fig. 2 shows a schematic diagram of an automatic driving assistance system for a vehicle according to another embodiment of the present invention.
As shown in fig. 2, in this embodiment, the electronic control unit 110 includes an adaptive cruise electronic control unit 1101, and the maneuvering gateway 120 includes a first maneuvering gateway 1201. One end of the first maneuvering gateway 1201 is connected with the adaptive cruise electronic control unit 1101 to receive the original longitudinal running control information sent by the adaptive cruise electronic control unit 1101. The other end of the first operating gateway 1201 is connected to the central gateway 130 to send a longitudinal control signal for controlling the vehicle to travel to the central gateway 130.
Herein, the first maneuvering gateway 1201 may be further configured to receive a first activation instruction and updated longitudinal running control information from the console 140, the first maneuvering gateway 1201 initiating an activation mode upon receiving the first activation instruction, the first maneuvering gateway 1201 resetting the original longitudinal running control information sent by the adaptive cruise electronic control unit 1101 to the updated longitudinal running control information in the activation mode, so that longitudinal running of the vehicle is controlled according to the updated longitudinal running control information.
In one embodiment, for illustration, it is assumed that the original longitudinal running control information sent by the adaptive cruise electronic control unit 1101 to the first maneuvering gateway 1201 is to cause the vehicle to run (with zero acceleration) at a constant first speed (e.g., 50 km/h). However, if it is detected that there is no vehicle or other obstacle within the previously set distance range and the road allows higher speed traveling within the speed limit range, the console 140 may transmit an activation command and updated longitudinal traveling control information to the first maneuvering gateway 1201 of the vehicle so that the vehicle accelerates in accordance with the updated longitudinal traveling control information. For example, the updated longitudinal running control information may be such that the vehicle is accelerated at an acceleration of 3m/s2Acceleration is performed and accelerated to a higher second speed (e.g., 80 km/h). The steering gateway 120 may initiate the active mode upon receiving the activation command, and reset the original longitudinal running control information using the updated longitudinal running control information and send the updated longitudinal running control informationInformation is sent to the central gateway 130, whereby the vehicle can be brought to a reset acceleration of 3m/s2And accelerating until the second speed is reached so as to adjust the running state of the vehicle.
Similarly, in another embodiment, for example, assuming that an emergency brake is required when it is detected that an obstacle exists ahead, the updated longitudinal running control information may also perform deceleration control of the vehicle at a deceleration that satisfies a requirement to avoid a collision of the vehicle with the obstacle. Due to the rapid response speed, the method can meet the requirement of timely and effective adjustment of the vehicle running state under various application scenes.
Fig. 3 shows a schematic diagram of an automatic driving assistance system for a vehicle according to yet another embodiment of the present invention.
As shown in fig. 3, the electronic control unit 110 includes an electric power steering electronic control unit 1102, and the steering gateway 120 includes a second steering gateway 1202, wherein one end of the second steering gateway 1202 is connected to the electric power steering electronic control unit 1102, and the other end of the second steering gateway 1202 is connected to the central gateway 130.
The second steering gateway 1202 may be further configured to receive a second activation instruction from the outside and updated lateral running control information, upon receiving the second activation instruction, the second steering gateway 1202 activating an activation mode in which the second steering gateway 1202 resets the original lateral running control information sent by the electric power steering electronic control unit 1102 to the updated lateral running control information so that lateral running of the vehicle is controlled according to the updated lateral running control information.
Specifically, for example, when the vehicle encounters an obstacle in front of the vehicle and needs to change the lane or the vehicle enters a turning section, the console 140 sends a second activation command and updated lateral driving control information to the second operation gateway 1202, and the second operation gateway 1202 performs the activation mode after receiving the second activation command. The updated lateral running control information is, for example, that the steering wheel is rotated by 10 ° every second until a specified direction is reached or that the vehicle is steered to a set angle or the like. The original lateral travel control information may be to turn the steering wheel at zero degrees or at different amplitudes, etc. In this embodiment, the second steering gateway 1202 resets the original lateral running control information to the updated lateral running control information in the active mode and transmits to the central gateway 130 so that the steering wheel is rotated 10 ° every second until a designated direction or the vehicle is steered to a set angle.
