[0026] CAN line, the full name of which is "Controller Area Network", is a serial communication protocol bus used for real-time applications.
[0027] At present, automobiles have become important means of transportation in production and life. The detection of automobile generators is an important detection link before the automobile leaves the factory. The generator will generate a resolver signal during operation and send the resolver signal to the generator control module. After the generator control module receives the resolver signal, it decodes the resolver signal through software or hardware structure to obtain the actual position and speed information of the generator. The generator control module controls the operation of the generator according to the actual position and speed information of the generator. When testing the generator, it is necessary to verify the corresponding changes when the generator control module does not receive the resolver signal. If the generator control module does not receive the resolver signal after a certain preset time, the generator control module will shut down. In the related technology, the control of the instantaneous disconnection of the resolver signal is achieved through a professional resolver simulator, but the operation of the professional resolver simulator is complicated, the equipment cost is high, and the equipment utilization is low, so it cannot be widely used.
[0028] like Figure 1 As shown, the present application provides a control device for a vehicle equipment rotary transformer signal, which is used to control the rotary transformer signal to produce an instantaneous disconnection. The device includes a host computer, a communication module, a first relay, and a second relay. The control device is arranged on the vehicle equipment, the host computer is connected to the communication module, the communication module is respectively connected to the first relay and the second relay, the first end of the first relay is connected to the first end of the second relay, the second end of the first relay is connected to the second end of the second relay, the vehicle equipment is connected to the first relay and the second relay, the control device receives the rotary transformer signal sent by the vehicle equipment, and constructs an instantaneous disconnection of the rotary transformer signal through the first relay and / or the second relay to return the signal to the vehicle equipment.
[0029] In detail, Figure 1 As shown, the host computer and the communication module are connected via a data line, which is used to send control instructions from the host computer to the communication module via the data line.
[0030] In detail, Figure 1As shown, the communication module is connected to the control end of the first relay through the CAN line, and the communication module is connected to the control end of the second relay through the CAN line. Specifically, the control instruction sent by the host computer to the communication module is transmitted to the control end of the first relay and the control end of the second relay through the CAN line to control the working state of the first relay and the second relay.
[0031] In detail, Figure 1 As shown, the first end of the first relay is connected to the first end of the second relay through the resolver wiring harness, and the second end of the first relay is connected to the second end of the second relay through the resolver wiring harness.
[0032] In more detail, Figure 2 As shown, the communication module is also connected to the vehicle equipment via a CAN line to collect the operating data of the vehicle equipment.
[0033] In more detail, Figure 2 As shown, the vehicle equipment provides operating voltage to the first relay and the second relay through a power line.
[0034] In detail, Figure 2 As shown, the vehicle equipment includes a generator and a generator control module.
[0035] In more detail, Figure 2 As shown, the generator is connected to the first end of the first relay through the resolver wiring harness, and the second end of the second relay is connected to the generator control module through the resolver wiring harness.
[0036] In more detail, Figure 2 As shown, the generator sends a resolver signal to the first relay or the second relay through the resolver wiring harness, and the generator control module receives the resolver signal sent by the first relay or the second relay. Figure 2 As shown, the resolver harness is used to transmit the resolver signal sent by the generator to the generator control module through the first relay or the second relay.
[0037] like Figures 1 to 4 As shown, the working principle of the control device for vehicle equipment resolver signal provided by the present application is as follows:
[0038] The host computer sends the control command of the relay to the communication module through the data line. Before the resolver signal is instantly disconnected, the communication module sends a first control signal to make the first relay in a normally open state, and the communication module sends a second control signal to the second relay to make the second relay in a normally closed state. The control of the first relay and the second relay is realized based on the function of the relay itself.
[0039] Since there is a mechanical error when the relay is disconnected and connected, the mechanical error of the relay is eliminated by the mutual cooperation between the first relay and the second relay.
[0040] If the preset time for the generator control module to report an abnormal alarm of the rotary transformer signal is 10ms, the disconnection and conduction time between the first relay and the second relay is set according to the preset time, the disconnection time of the second relay is t1, the conduction time of the first relay is t2, and the time interval between the conduction time t2 of the first relay and the disconnection time t1 of the second relay is Δt. The time for sending the control signal is adjusted by the upper computer, and the value of the delayed disconnection time t1 is adjusted. When the time interval Δt is less than the preset time 10ms, the generator control module does not report an abnormal alarm of the rotary transformer signal. When the time interval Δt is greater than or equal to the preset time 10ms, the generator control module reports an abnormal alarm of the rotary transformer signal, and realizes instantaneous cut-off control of the rotary transformer signal to achieve millisecond-level precision control.
[0041] It should be noted that the preset time for reporting the abnormal alarm of the rotary transformer signal is set according to actual needs.
[0042] like Figure 3 As shown, when the first relay is disconnected and the second relay is turned on, the resolver signal sent by the generator flows into the generator control module after passing through the second relay; Figure 4 As shown, when the first relay is turned on and the second relay is turned off, the resolver signal sent by the generator flows into the generator control module after passing through the first relay.
[0043] The vehicle equipment provides working power to the first relay and the second relay through the power line. Since the first relay and the second relay send control signals through the CAN line, the communication module can collect test data of the two relays through the CAN line, and at the same time collect operating data of the vehicle equipment through the CAN line to facilitate staff analysis of the data.
[0044] The present application also provides a vehicle device, including the control device for the resolver signal of the vehicle device as described above, which is convenient for controlling the instantaneous interruption of the resolver signal in the vehicle.
[0045] The present application provides a control device for a rotary signal of a vehicle equipment and a vehicle equipment, the control device includes a host computer, a communication module, a first relay, and a second relay, the control device is arranged on the vehicle equipment, the vehicle equipment includes a generator and a generator control module, the host computer is connected to the communication module, the communication module is connected to the first relay and the second relay respectively, the first end of the first relay is connected to the first end of the second relay, the second end of the first relay is connected to the second end of the second relay, the generator is connected to the first end of the first relay, and the second end of the second relay is connected to the generator control module, the control device receives the rotary signal sent by the generator, and constructs the instantaneous disconnection of the rotary signal through the first relay and / or the second relay to return the signal to the vehicle equipment.
