Fig. 1 is a schematic view of a portion of a vehicle according to an embodiment of the present application. As shown in fig. 1, the vehicle includes a power supply battery 10 and a vehicle control circuit 20. The vehicle control circuit 20 is electrically connected to the power supply battery 10. The vehicle control circuit 20 includes a battery connection terminal 201, an ABS controller 21, and an electronic control switch 22. The battery connection terminal 201 is electrically connected to the power supply battery 10, and the power supply battery 10 supplies power through the battery connection terminal 201. The electric control switch 22 is electrically connected with the battery connection terminal 201 and the ground terminal 202. The ABS controller 21 includes a connection port 211 and a detection port 212. In the present embodiment, the ABS controller 21 is connected to the electronic control switch 22 through the connection port 211. The connection port 211 is also used to connect with an ASR solenoid valve 30 of an ASR system. One end of the ASR solenoid valve 30 is connected to the connection port 211, and the other end is connected to the ground 202. The electric control switch 22 can be controlled to be switched on and off by an electric signal. With the electronically controlled switch 22 closed, the battery connection 201 is electrically connected to ground 202 through the ASR solenoid valve 30 and forms a passageway 203 (as indicated by the arrow in fig. 1). The ABS controller 21 is electrically connected to the via 203 through the detection port 212. The ABS controller 21 detects the on/off of the passage 203 through the detection port 212.

In the embodiment shown in fig. 1, the electronically controlled switch 22 is closed synchronously when the vehicle is ignited, and the ABS controller 21 detects the voltage of this path 203 through the detection port 212. When the voltage of the passage 203 is detected to reach the voltage threshold, it indicates that the ASR solenoid valve 30 is electrically connected to the connection port 211. In this embodiment, the voltage of the power supply battery 10 is 24V, and the voltage threshold may be set to 24V. When the vehicle fires and the electronic control switch 22 is closed and the configuration detection stage is entered, if the ASR solenoid valve 30 is connected to the connection port 211, the power supply battery 10, the connection port 211, the ASR solenoid valve 30 and the ground 202 form a path 203 (as indicated by an arrow in fig. 1), and the voltage of the path 203 detected by the detection port 212 is 24V of the voltage of the power supply battery 10. If the connection port 211 is not connected to the ASR solenoid valve 30, the power supply battery 10 and the connection port 211 do not form a passage 203 with the ASR solenoid valve 30 and the ground 202, and at this time, the passage 203 is disconnected, and the voltage detected by the detection port 212 is 0V, and cannot reach the set voltage threshold 24V. Thus, detecting the voltage value of the passage 203 through the detection port 212 can determine whether the system is connected with the ASR solenoid valve 30, thereby determining whether the vehicle is configured as a stand-alone ABS system or the ABS system is combined with the ASR system. The single ABS system is configured with a corresponding first control program, the combination of the ABS system and the ASR system is configured with a second control program, and after the system configuration is determined, the corresponding first control program or the second control program is directly called. In this way, the vehicle is self-inspected before use. At the time of self-test, the vehicle is started by controlling the ignition switch of the vehicle to perform ignition. At the same time as the vehicle fires, the electronically controlled switch 22 is controlled to close synchronously, so that the power supply battery 10, the connection port 211, the ASR solenoid valve 30 and the ground 202 form a path 203. The on-off state of the ASR solenoid valve 30 and the connection port 211 can be determined by detecting the voltage of the passage 203 through the detection port 212. When it is determined that the ASR solenoid valve 30 is connected to the connection port 211, a control program of the ASR system may be invoked at any time according to actual requirements. According to the scheme, the vehicle configuration can be more simply identified, the management and control difficulty of a vehicle system is reduced, and the cost is lower.

In the embodiment shown in fig. 1, after detecting that the ASR solenoid valve 30 is connected to the connection port 211, in the actual use process, the ASR solenoid valve 30 is kept in a normally closed state, and the on-off of the channel 203 can be controlled by controlling the on-off of the electric control switch 22, so as to control the on-off of the ASR system, so as to meet the current actual use requirement and reduce the difficulty in controlling the vehicle system.

In other embodiments, the voltage of the power supply battery 10 may be set to 12V or 10V, the voltage threshold value may be set to 12V or 10V, or the like, respectively. Thus, the device can be flexibly configured according to actual conditions.

In this embodiment, the ABS system is an indispensable system, and the ASR system is an optional system. In a vehicle equipped with an ASR system in part, the ASR system is mounted on the ABS system to control the ABS system and the ASR system. By adopting the vehicle control circuit 20 provided by the embodiment of the application, the electric control switch 22 is controlled to be closed while the vehicle fires, and if the connection port 211 is connected with the grounded ASR electromagnetic valve 30 at this time, the battery connection end 201, the electric control switch 22 and the ASR electromagnetic valve 30 can form a passage. If the connection port 211 is not connected to the ASR solenoid valve 30, the passage cannot be formed, and the passage is opened. By analyzing the data collected by the detection port 212, it can be determined whether the channel 203 is connected, thereby determining whether the system is connected with the ASR electromagnetic valve 30, further determining that the vehicle is configured as a single ABS system, or the ABS system and the ASR system are combined, and calling a corresponding program to realize vehicle control. Therefore, the present embodiment can determine whether the vehicle is configured as an ABS system alone or the ABS system and the ASR system are combined by determining whether the ABS system is equipped with the ASR system. Therefore, the vehicle configuration can be more simply identified, and the control difficulty of the vehicle system is reduced.

In this embodiment, the connection port 211 includes a connection pin that mates with a connection pin of the ASR solenoid valve 30. The two connecting pins are in plug-in connection, so that a stable current path can be realized, and the interference is not easy to occur. And two connection pins are connected in a plugging manner, and the connection mode is rapid and stable.

Fig. 2 is a schematic wiring diagram of a vehicle according to another embodiment of the present application. The embodiment shown in fig. 2 is similar to the embodiment shown in fig. 1, with the main difference that the vehicle control circuit 20 further comprises a safety switch 23 electrically connected between the battery connection terminal 201 and the electronic control switch 22. Under normal conditions, the safety switch 23 is in a normally closed state, and under abnormal conditions of the circuit, the safety switch 23 is automatically opened to automatically cut off the circuit. By providing the safety switch 23, the circuit can be cut off in the event of abnormality in the circuit, and protection of each device in the vehicle control circuit 20 can be achieved, improving safety.

In the embodiment shown in fig. 2, the vehicle control circuit 20 further includes a detection module 24 connected between the detection port 212 and the passageway 203. The detection module 24 is configured to detect a voltage of the channel 203 and transmit the detected voltage information to the detection port 212. In this embodiment, the detection module 24 includes a sensor. The voltage of the path 203 is detected by the sensor with high accuracy.

In the embodiment shown in fig. 2, the electronically controlled switch 22 comprises a solenoid valve that is controllably opened or closed. The ABS controller 21 further includes a control port 213 electrically connected to the solenoid valve. At the time of ignition of the vehicle, the ABS controller 21 controls the solenoid valves to be closed synchronously through the control port 213, thereby turning on or off the passage 203 between the power supply battery 10 and the ASR solenoid valve 30. When the vehicle ignites, a control signal is sent to the electromagnetic valve through the control port 213 to control the on-off of the electromagnetic valve. In this embodiment, when the ABS controller 21 controls the solenoid valve to close through the control port 213, the passage 203 between the power supply battery 10 and the ASR solenoid valve 30 is turned on. At this time, the ABS controller 21 detects the voltage of the channel 203 through the detection port 212. When the detection port 212 detects that the voltage of the channel 203 reaches the voltage threshold, it is explained that the connection port 211 communicates with the ASR solenoid valve 30, and the power supply battery 10, the solenoid valve, the connection port 211, the ASR solenoid valve 30, and the ground 202 form the channel 203 (as indicated by the arrow in fig. 2). In this embodiment, by setting the electric control switch 22 as an electromagnetic valve, the on-off of the passage 203 is switched by the electromagnetic valve, so that the sensitivity is high, the control is accurate, and the cost is low.

In practical application, the vehicle control circuit 20 is provided with an ASR system, and the system configuration includes an ABS system and an ASR system, and invokes a corresponding control program in the case of combining the ABS system and the ASR system. If the voltage detected by the detection port 212 does not reach the voltage threshold, it is indicated that the power supply battery 10, the solenoid valve, and the connection port 211 do not form the passage 203 with the ASR solenoid valve 30, and at this time, the connection port 211 is not connected to the ASR solenoid valve 30, the ASR system is not provided in the vehicle control circuit 20, and the system is configured as an individual ABS system, and at this time, a control program corresponding to the individual ABS system is called. If the voltage detected by the detection port 212 reaches the voltage threshold, it is indicated that the power supply battery 10, the electromagnetic valve, the connection port 211 and the ASR electromagnetic valve 30 form the passage 203, and at this time, the connection port 211 is connected with the ASR electromagnetic valve 30, the ASR system is set in the vehicle control circuit 20, and the system is configured as an ABS system and an ASR system, and at this time, control programs corresponding to the ABS system and the ASR system are invoked. By the arrangement, the control difficulty of the vehicle system is reduced.

Fig. 3 is a schematic wiring diagram of a vehicle according to another embodiment of the present application. The embodiment shown in fig. 3 is similar to the embodiment shown in fig. 2, with the main difference that the electronically controlled switch 22 includes a main relay electrically connected between the battery connection terminal 201 and the connection port 211. At the time of ignition of the vehicle, the main relay is synchronously closed, and the ABS controller 21 detects the voltage of the passage 203 through the detection port 212. When the voltage detected by the detection port 212 reaches the voltage threshold, it is explained that the connection port 211 communicates with the ASR solenoid valve 30, and the power supply battery 10, the main relay, the connection port 211, the ASR solenoid valve 30, and the ground 202 form a passage 203 (as indicated by an arrow in fig. 3). Compared with an electromagnetic valve, the main relay has higher sensitivity and larger control range, can be flexibly configured, increases the use field, and is stable and reliable.

In practical application, the vehicle control circuit 20 is provided with an ASR system, and the system configuration includes an ABS system and an ASR system, and invokes a corresponding control program in the case of combining the ABS system and the ASR system. If the detection port 212 detects that the voltage does not reach the voltage threshold, it indicates that the power supply battery 10, the main relay, and the connection port 211 do not form the passage 203 with the ASR solenoid valve 30, and at this time, the connection port 211 is not connected to the ASR solenoid valve 30, the ASR system is not provided in the vehicle control circuit 20, and the system is configured as an individual ABS system, and at this time, a control program corresponding to the individual ABS system is called. If the detection port 212 detects that the voltage reaches the voltage threshold, it indicates that the power supply battery 10, the main relay, the connection port 211 and the ASR solenoid valve 30 form a channel 203, at this time, the connection port 211 is connected to the ASR solenoid valve 30, an ASR system is set in the vehicle control circuit 20, and the system is configured as an ABS system and an ASR system, at this time, control programs corresponding to the ABS system and the ASR system are invoked. By the arrangement, the control difficulty of the vehicle system is reduced.

In the present embodiment, the main relay includes a main coil 221 and a main contact switch 222 connected to the main coil 221. Wherein the main winding 221 is grounded. When the vehicle ignites, the main coil 221 is energized and drives the main contact switch 222 to be synchronously closed, so that the connection port 211 is electrically connected with the battery connection terminal 201. Thus, when the vehicle is ignited, an electric signal is input to the main coil 221, and the main contact switch 222 is energized to synchronously close the ABS controller 21, thereby detecting the voltage of the passage 203 through the detection port 212. When the detection port 212 detects that the voltage of the passage 203 reaches the voltage threshold, it is determined that the ASR solenoid valve 30 is connected to the vehicle control circuit 20 by indicating that the power supply battery 10, the main contact switch 222, the connection port 211, and the ASR solenoid valve 30 and the ground 202 form the passage 203 (as indicated by an arrow in fig. 3). When the main coil 221 of the main relay of the present embodiment is energized, the main contact switch 222 is synchronously closed, and the sensitivity is high and the control is accurate. Compared with the electromagnetic valve, the controlled signal type is different, so that the configured electric control circuit is different, the circuit is simple, the cost is low, and the electromagnetic valve can adapt to different scenes.

In practical application, the vehicle control circuit 20 is provided with an ASR system, and the system configuration includes an ABS system and an ASR system, and invokes a corresponding control program in the case of combining the ABS system and the ASR system. If the detection port 212 detects that the voltage does not reach the voltage threshold, it indicates that the power supply battery 10, the main contact switch 222, and the connection port 211 do not form the passage 203 with the ASR solenoid valve 30, and at this time, the connection port 211 is not connected to the ASR solenoid valve 30, the ASR system is not provided in the vehicle control circuit 20, and the system is configured as an individual ABS system, and at this time, a control program corresponding to the individual ABS system is called. If the detection port 212 detects that the voltage reaches the voltage threshold, it indicates that the power supply battery 10, the main contact switch 222, the connection port 211 and the ASR solenoid valve 30 form a channel 203, at this time, the connection port 211 is connected with the ASR solenoid valve 30, an ASR system is set in the vehicle control circuit 20, and the system is configured as an ABS system and an ASR system, at this time, control programs corresponding to the ABS system and the ASR system are invoked. By the arrangement, the control difficulty of the vehicle system is reduced.

Fig. 4 is a schematic wiring diagram of a vehicle according to another embodiment of the present application. The embodiment shown in fig. 4 is similar to the embodiment shown in fig. 3, with the main difference that electronically controlled switch 22 includes a main relay and an auxiliary relay. Both the main electrical appliance and the auxiliary relay are connected between the battery connection terminal 201 and the connection port 211. When the vehicle ignites, the main relay and the auxiliary relay are synchronously closed. In this way, the main relay and the auxiliary relay are provided in the circuit, so that it is possible to prevent a situation in which ASR configuration cannot be recognized due to a single control path failure, and to contribute to improvement of the stability of the operation of the vehicle control circuit 20. In the present embodiment, the main relay includes a main coil 221 and a main contact switch 222 connected to the main coil 221. The auxiliary relay includes an auxiliary coil 223 and an auxiliary contact switch 224 connected to the auxiliary coil 223. Both the main coil 221 and the auxiliary coil 223 are grounded. When the vehicle ignites, the main coil 221 is energized and drives the main contact switch 222 to be synchronously closed, so that the connection port 211 is electrically connected with the battery connection terminal 201. At the same time, the auxiliary coil 223 is energized and drives the auxiliary contact switch 224 to close, so that the connection port 211 is electrically connected with the battery connection terminal 201. Thus, when the vehicle is ignited, an electric signal is input to the main coil 221 and the auxiliary coil 223, the main coil 221 is energized and the auxiliary contact switch 224 is attracted and the main contact switch 222 is synchronously closed, and the auxiliary coil 223 is energized and the auxiliary contact switch 224 is attracted and closed. The voltages of the first path 204 and the second path 205 are detected through the detection port 212. If the detection port 212 detects that the voltage of the first channel 204 reaches the voltage threshold, it indicates that the power supply battery 10, the main contact switch 222, the connection port 211, the ASR solenoid valve 30 and the ground terminal 202 form the first channel 204 (as shown in fig. 4); if the detection port 212 detects that the voltage of the second path 205 reaches the voltage threshold, it is explained that the power supply battery 10, the auxiliary contact switch 224, the connection port 211, and the ASR solenoid valve 30 and the ground terminal 202 form the second path 205 (as shown in fig. 4). In this embodiment, by providing two paths (the first path 204 and the second path 205), when one path fails or fails, the other path can work normally, and the detection path is ensured to be conducted, so that the detection can be completed smoothly, and the two paths serve as dual detection paths, so that the safety is higher.

In practical application, the vehicle control circuit 20 is provided with an ASR system, and the system configuration includes an ABS system and an ASR system, and invokes a corresponding control program in the case of combining the ABS system and the ASR system. If the detection port 212 detects that the voltage does not reach the voltage threshold, it is indicated that the power supply battery 10, the main contact switch 222, and the connection port 211 do not form the first path 204 with the ASR solenoid valve 30 and the ground terminal 202, and that the power supply battery 10, the auxiliary contact switch 224, and the connection port 211 do not form the second path 205 with the ASR solenoid valve 30 and the ground terminal 202, and that the ASR system is not provided in the vehicle control circuit 20, and the system is configured as a separate ABS system, and at this time, a control program corresponding to the separate ABS system is called. If the detection port 212 detects that the voltage reaches the voltage threshold, it indicates that the power supply battery 10, the main contact switch 222, the connection port 211, the ASR solenoid valve 30 and the ground 202 form a first path 204, and/or the power supply battery 10, the auxiliary contact switch 224, the connection port 211, the ASR solenoid valve 30 and the ground 202 form a second path 205, at this time, the connection port 211 is connected to the ASR solenoid valve 30, an ASR system is set in the vehicle control circuit 20, and the system is configured as an ABS system and an ASR system, and at this time, control programs corresponding to the ABS system and the ASR system are invoked. By the arrangement, the control difficulty of the vehicle system is reduced.

In other embodiments, the electronically controlled switch 22 may also include only an auxiliary relay electrically connected between the battery connection 201 and the connection port 211, which is closed simultaneously when the vehicle is ignited. The auxiliary coil 223 of the auxiliary relay is grounded. When the vehicle ignites, the auxiliary coil 223 is energized and drives the auxiliary contact switch 224 to be synchronously closed, so that the connection port 211 is electrically connected with the battery connection terminal 201. Thus, when the vehicle is ignited, an electric signal is input to the auxiliary coil 223, and the auxiliary contact switch 224 is energized and attracted to simultaneously close the ABS controller 21. The voltage of the channel 203 is detected through the detection port 212. When the detection port 212 detects that the voltage of the passage 203 reaches the voltage threshold, it is determined that the ASR solenoid valve 30 is connected to the vehicle control circuit 20 by indicating that the power supply battery 10, the auxiliary contact switch 224, and the connection port 211 form a passage (as indicated by an arrow in fig. 3) with the ASR solenoid valve 30 and the ground terminal 202.
