The simulation device can establish communication connection with an operation terminal through the communication module. The communication module may adopt a wired or wireless communication mode, and in this embodiment, a wireless communication module, specifically, a WiFi communication module is adopted. The operation terminal may be a dedicated operation terminal, or may be an electronic device such as a computer, a tablet, a mobile phone, or the like, and may remotely send a command to the brake controller simulation device based on the operation terminal. Specifically, a brake level input instruction is sent to the analog device via the operation terminal.
In some embodiments, the relay circuit includes a manual control switch matrix and an automatic control switch matrix, both connected to the control module. And the input end of the manual control switch matrix is connected with the brake controller, the output ends of the manual control switch matrix and the automatic control switch matrix are connected to the output port, and the simulation device is connected with the vehicle brake device through the connector on the vehicle side by virtue of the output port. And a relay is arranged on each input line of the manual control switch matrix and the automatic control switch matrix. As shown in fig. 2, the manual control switch matrix includes K1, K2 and K3, and the automatic control switch matrix includes K4, K5 and K6, and the opening and closing of the automatic control switch matrix are controlled by the control module.
The control module is configured to pre-store the corresponding relation between the level and the output voltage and the relay circuit on-off, and comprises:
the control mode switching unit is used for initializing the connection or disconnection of the manual control switch matrix or the automatic control switch matrix in response to a control mode instruction sent by the operation terminal, and if the manual control mode is adopted, the relays on the input line of the manual control switch matrix are all closed, and the relays on the input line of the automatic control switch matrix are all disconnected; if the automatic control mode is adopted, all relays on the input line of the manual control switch matrix are initialized to be disconnected, all relays on the input line of the automatic control switch matrix are disconnected, and the level handle of the driver is not available.
And the automatic control unit is used for controlling one or more relays corresponding to the level to be communicated according to the corresponding relation between the prestored level and the on-off of the multiple relay circuits if the current control mode is the automatic control mode, responding to the level input instruction sent by the operation terminal, so that the corresponding circuits are electrified, and a voltage signal corresponding to the braking level is generated and transmitted to the vehicle braking device through the connector. It will be appreciated by those skilled in the art that if the current control mode is a manual control mode, the circuit corresponding to the input stage can be energized when the stage handle is adjusted, thereby transmitting voltage to the vehicle side brake.
