In some embodiments, the vehicle control unit 40 further includes a plurality of ECU's 44 for executing control commands, and each ECU44 is electrically connected to the on-board unit 20 via a vehicle bus.
In the vehicle control system provided by the embodiment of the invention, the processor, the fuse and the fuse are arranged in the safety control unit, so that when the control message received by the vehicle contains the preset abnormal instruction, the processor controls the fuse to increase the voltage difference exceeding the preset threshold value at the two ends of the fuse, the fuse is fused, the electrical connection between the vehicle-mounted unit and the vehicle control unit is disconnected, the vehicle recovers normal operation, the vehicle operation safety is ensured, and the detachable structure of the fuse is arranged, so that the fuse can be replaced again after the vehicle recovers normal operation, and the remote control mode of the vehicle is recovered.
In order to implement the foregoing embodiment, the present invention further provides a vehicle control method, which is applied to the vehicle control system described in the foregoing embodiment, where the vehicle control system includes an on-board unit for generating a control instruction according to a control message of an internet of vehicles, and a vehicle control unit for executing the control instruction, and fig. 4 is a schematic flow chart of the vehicle control method provided in the embodiment of the present invention, and as shown in fig. 4, the method includes the following steps:
Specifically, the vehicle is in the internet of vehicles, and a terminal in the internet of vehicles can realize remote control of the vehicle through an installed application program, wherein the terminal can be a mobile phone, a palm computer, a mobile computer, an IPAD and the like. The terminal sends control messages to a background server of the Internet of vehicles, the background server transmits the control messages through the base stations, and the communication unit receives the control messages from the base stations through communication connection among the base stations in the Internet of vehicles and sends the control messages to the safety control unit.
As a possible implementation manner, whether the security verification passes is determined according to whether the control message contains a preset abnormal instruction.
Specifically, the safety control unit performs safety verification on the received control message to determine whether the control message contains a preset abnormal instruction. As a possible implementation, the exception instruction can be guaranteed not to be abused by itself through a token rolling algorithm or a message signature algorithm, and can also be guaranteed to be uniquely identified.
And step 403, if the safety verification is not passed, disconnecting the electrical connection between the vehicle-mounted unit and the vehicle control unit.
Specifically, if the safety control unit fails to verify the safety of the control message, it indicates that the control message includes a preset abnormal instruction, where the abnormal instruction is used to indicate that the vehicle has been illegally controlled and needs to disconnect the electrical connection between the onboard unit and the vehicle control unit, and specifically, the processor of the safety control unit may indicate the fuse to apply a voltage difference greater than a threshold value to two ends of the fuse, so that the fuse is fused by the generated heat under the action of the instantaneous large current, thereby disconnecting the electrical connection between the onboard unit and the vehicle control unit, so that the vehicle cannot receive the remote control message, and the vehicle returns to a normal operation state.
For example, when the internet of vehicles is invaded by a hacker, the vehicle is controlled by the hacker, the hacker can send a control message which enables the vehicle to be in a dangerous operation state, the vehicle can prompt the vehicle to be controlled in an active mode such as giving out warning tone, or a vehicle control department determines that the vehicle is controlled by analyzing the operation condition of the vehicle, and after the vehicle is determined to be possibly controlled, the vehicle control department can send a preset abnormal instruction message through a base station, so that after the safety control unit receives the abnormal instruction message, the abnormal control instruction is identified, the electrical connection between the vehicle-mounted unit and the vehicle control unit is disconnected, the vehicle-mounted unit of the vehicle does not receive the control message any more, the remote control is disconnected, and the normal operation state of the vehicle is recovered.
As a possible implementation mode, after the vehicle recovers the normal operation, the fuse in the safety control unit can be replaced, the convenience of vehicle maintenance is improved, and the safety of vehicle operation is improved while the control mode of vehicle operation is increased.
And step 404, if the safety verification is passed, sending a control message to the vehicle-mounted unit so that the vehicle-mounted unit generates a control instruction for controlling the vehicle control unit according to the control message.
Specifically, if the safety verification passes, it is indicated that the control message does not include a preset abnormal instruction, and the electrical connection between the on-board unit and the vehicle control unit does not need to be disconnected, the control message is continuously sent to the on-board unit, so that the on-board unit generates a control instruction for controlling the vehicle control unit according to the control message.
According to the vehicle control method, the control message of the Internet of vehicles is acquired, the control message is subjected to safety verification, if the safety verification fails, the electrical connection between the vehicle-mounted unit and the vehicle control unit is disconnected, if the safety verification passes, the control message is sent to the vehicle-mounted unit, so that the vehicle-mounted unit generates a control instruction for controlling the vehicle control unit according to the control message, the safety control unit is arranged, when the control message cannot pass the safety verification, the electrical connection between the vehicle-mounted unit and the vehicle control unit is disconnected, the safety operation of the vehicle is recovered, and when the control message passes the safety verification, the vehicle is controlled to continue to operate normally, and the safety of the vehicle operation is improved.
