For example, the first board 1 may be an input/output board VT2516, VT2848, or the like, which is not limited herein. The first board card 1 has multiple input/output channels, and can be connected to signal input pins of the vehicle body controller 3. Illustratively, the first channel of the first board card 1 is connected with a pin of a one-key start switch of the vehicle body controller 3, the second channel is connected with a pin of a brake pedal switch of the vehicle body controller 3, and the third channel is connected with a pin of a clutch pedal switch of the vehicle body controller 3.

After a hardware test platform for testing the power supply gear function is built, a software test platform corresponding to the hardware test platform needs to be built so as to realize automatic testing of the power supply gear function.

By way of example, the test software may be canoe (can open environment) software, vtestudio software, or the like. The CANoe software is an automobile network development software platform integrating integrated line simulation, recording and testing. The vtestudio software is test case writing software. Specifically, the first board card 1, the second board card 2, and the third board card 3 may be configured through CANoe software to establish a mapping relationship between the software test platform and the hardware test platform. Illustratively, corresponding to the hardware test platform, the first channel of the first board 1 is configured to be connected with a one-key start switch pin of the vehicle body controller 3, the second channel of the first board 1 is configured to be connected with a brake pedal switch pin of the vehicle body controller 3, and the third channel of the first board 1 is configured to be connected with a clutch pedal switch pin of the vehicle body controller 3.

The vtestudio software is used for generating a test script based on the configuration information and the test case, and executing the generated test script in the CANoe software, so that a power supply gear test instruction is sent to the first board card 1, and then a power supply gear test signal is sent to the vehicle body controller 3 by the first board card 1, so that the vehicle body controller 3 controls at least one power supply gear relay to work according to the power supply gear test signal. And the CANoe software can also be used for receiving a measurement result of at least one power supply gear relay voltage sent by the measurement module and determining whether the power supply gear function corresponding to the power supply gear test signal is normal or not according to the measurement result.
By adopting the technical scheme, the first board card 1 can send a power supply gear test signal to the automobile body controller 3 when receiving a power supply gear test instruction from the upper computer 4; the measuring module can measure the voltage of at least one power supply gear relay and send a measuring result to the upper computer 4, so that the upper computer 4 determines whether the power supply gear function corresponding to the power supply gear testing signal is normal or not according to the measuring result. Like this, keep off position function test system through setting up this power, can keep off the position function to the power and carry out automated test, need not the tester and test on the real car to reduce the cost of labor, avoided the error of manual test, improved the security of efficiency of software testing, degree of accuracy and test.
Optionally, the system further comprises an upper computer 4.
Optionally, the plurality of power range relays include a first type relay, a second type relay, and a third type relay, where, for different power ranges, the working state combinations formed by the respective working states of the first type relay, the second type relay, and the third type relay are different.
In the disclosed embodiment, the first type of relay may include one or more ACC relays, the second type of relay may include one or more IG1 relays, and the third type of relay may include one or more IG2 relays. Specifically, if the first type of relay includes an ACC relay, the second type of relay includes an IG1 relay, and the third type of relay includes an IG2 relay, the second board card 2 and the body controller 3 may be connected when the hardware test platform is built. For example, the first channel of the second board 2 is connected to an ACC relay pin of the vehicle body controller 3, the second channel of the second board 2 is connected to an IG1 relay pin of the vehicle body controller 3, and the third channel of the second board 2 is connected to an IG2 relay pin of the vehicle body controller 3.
And aiming at different power supply gears, the working state combinations formed by the respective working states of the first type relay, the second type relay and the third type relay are different. Specifically, there are 4 power gears in this disclosure, OFF gear, ACC gear, ON gear, STRAT gear, respectively. The vehicle body controller 3 can control the working states of the first type relay, the second type relay and the third type relay to enable the vehicle to be in different power supply gears. For example, in the OFF range, the first type relay, the second type relay, and the third type relay are all in the OFF state, that is, the ACC relay, the IG1 relay, and the IG2 relay are all in the OFF state. When the relay is in the ACC gear, the first type relay is in an attraction state, the second type relay and the third type relay are in an off state, namely, the ACC relay is in the attraction state, and the IG1 relay and the IG2 relay are in the off state. When the gear is ON, the first type relay, the second type relay and the third type relay are all in the attraction state, namely, the ACC relay, the IG1 relay and the IG2 relay are all in the attraction state. When the STRAT gear is in the gear, the second type relay is in an attraction state, and the first type relay and the third type relay are in a disconnection state. That is, the IG1 relay is in the pull-in state, and the ACC relay and the IG2 relay are in the off state.
Optionally, the first board card 1 is further configured to receive a power supply gear function normal instruction from the upper computer 4, and send the power supply gear function normal instruction to the vehicle body controller 3, so as to notify the vehicle body controller 3 that the power supply gear function is normal.
In practical application, after the vehicle body controller 3 normally opens the control power supply gear, if an instruction indicating that the power supply gear function is normal is not received, the control power supply gear relay is disconnected, and therefore, in the disclosure, the first board card 1 is further used for receiving a power supply gear function normal instruction from the upper computer 4 and sending the power supply gear function normal instruction to the vehicle body controller 3 to inform the vehicle body controller 3 that the power supply gear function is normal, so that normal operation of power supply gear function testing is ensured.
In the practical application process, the vehicle can be in different power supply gears by pressing one key to start the switch. Specifically, assuming that the initial state of the power range is the OFF range, the one-touch START switch is pressed once to perform the switching of the power range in the order of the OFF range, the ACC range, the ON range, and the OFF range, and in the ACC range, the ON range, or the OFF range, the power range is switched to the START range by pressing the one-touch START switch and depressing the brake pedal (automatic transmission) or the clutch pedal (manual transmission), and the pressing of the one-touch START switch is equivalent to sending a valid signal, such as a high level signal, to the one-touch START switch pin of the body controller 3. Based on this, the tester can compile corresponding test case through test software to realize the test to power position function.
Optionally, when the power supply gear test instruction indicates to test the ACC gear function, the first board card 1 is configured to send an ACC gear function test signal to a one-key start switch pin of the vehicle body controller 3, so that the vehicle body controller controls the first type of relay to be attracted, and the second type of relay and the third type of relay to be kept off according to the ACC gear function test signal; or when the power supply gear test instruction indicates to test the ON gear function, the first board card 1 is used for sending an ON gear function test signal to a one-key starting switch pin of the vehicle body controller, so that the vehicle body controller controls the first type relay, the second type relay and the third type relay to be attracted according to the ON gear function test signal.
Referring to fig. 2, fig. 2 is a flowchart illustrating an ACC shift function testing method according to an exemplary embodiment. As shown in fig. 2, the method may include the following steps.
In S201, the power supply module is loaded.
Wherein the purpose of loading the power supply module is to supply power to the body controller 3. For example, power may be supplied to the body controller 3 through the third board.
In S202, the board initialization module is loaded.
The purpose of loading the board initialization module is to perform initialization configuration on the board so that the power supply gear is the OFF gear. Illustratively, following the above example, the one-touch start switch pin is active at a high level and inactive at a low level. The brake pedal switch pin and the clutch pedal pin are in an invalid state at a high level and in an valid state at a low level. Based on this, the first channel, the second channel, and the third channel of the first board 1, which are connected to the one-key start switch pin, the brake pedal switch pin, and the clutch pedal switch pin, respectively, can be configured to be in the inactive state. The second board card 2 is configured as a power supply gear relay, and specifically, the ACC relay in the second board card 2 may be connected to an ACC relay pin of the vehicle body controller 3 through the first channel of the second board card 2. The IG1 relay in the second board 2 is connected to the IG1 relay pin of the body controller 3 through the second channel of the second board 2. And the IG2 relay in the second board card 2 is connected with an IG2 relay pin of the automobile body controller 3 through a third channel. It should be noted that, reference may be made to the scheme in the prior art for configuring the second board card 2 as the power shift relay, and details are not described here.
In S203, an ACC shift function test signal is sent to a one-key start switch pin of the vehicle body controller 3 through the first board card 1.
The ACC shift function test signal is an input signal required by the vehicle body controller 3 to control the ACC shift to be turned on. That is, a high level signal is sent to the one-touch start switch pin through the first channel of the first board 1, so that the vehicle body controller 3 can control the first type relay (ACC relay) to pull in and the second type relay (IG1 relay) and the third type relay (IG2 relay) to keep off according to the high level signal.
In S204, it is determined whether the ACC range function is normal, and if so, step S205 is executed, and if not, step S206 is executed.
In S205, an ACC range function normal command is sent to the first board 1.
In S206, it is determined that the ACC range function is not implemented.
In this disclosure, the measurement module on the second board card 2 can be used to measure the voltage of the ACC relay, and send the measurement result to the upper computer, so that the upper computer determines whether the ACC gear function is normal according to the measurement result. Specifically, the upper computer stores preset conditions for determining whether the ACC gear functions are normal or not in advance. Illustratively, the preset condition is whether the voltage of the ACC relay is greater than or equal to a preset voltage threshold, e.g., 18V, and whether the voltages of the IG1 relay and the IG2 relay are 0V. If so, determining that the ACC gear function is normal, and if not, determining that the ACC gear function is not realized, namely, the power gear is not switched to the ACC gear.
By adopting the scheme, the real vehicle test is not required for testers, the automatic test of the ACC gear function is realized, the test time is shortened, and the test efficiency is improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating an ON-shift function testing method according to an exemplary embodiment. As shown in fig. 3, the method may further include steps S301 to S304 in addition to the above steps 201 and 202.
In S301, an ON-position function test signal is sent to a one-key start switch pin of the vehicle body controller 3 through the first board card 1.
In S302, it is determined whether the ON range function is normal, and if so, step S303 is performed, and if not, step 304 is performed.
In S303, an ON range function normal command is sent to the first board 1.
In S304, it is determined that the ON range function is not implemented.
Wherein, the ON shift function test signal is an input signal required when the vehicle body controller 3 controls the ON shift to be opened. After the board initialization module is loaded, the power shift position is in the OFF shift position, and in order to switch the power shift position to the ON shift position, a high level signal needs to be sent to the one-key start switch pin through the first channel of the first board 1 first, so that the power shift position is switched from the OFF shift position to the ACC shift position, and then a high level signal needs to be sent to the one-key start switch pin again, so that the power shift position is switched from the OFF shift position to the ON shift position. In this way, the vehicle body controller 3 can control the first type relay (ACC relay), the second type relay (IG1 relay), and the third type relay (IG2 relay) to pull in, according to the high level signals transmitted twice.
Then, the measurement module ON the second board card 2 may be configured to measure a voltage of the ACC relay, a voltage of the IG1 relay, and a voltage of the IG2 relay, and send a measurement result to the upper computer, so that the upper computer determines whether the ON shift function is normal according to the measurement result. Specifically, the upper computer stores preset conditions for determining whether the ON gear function is normal or not in advance. Illustratively, the preset condition is whether the voltage of the ACC relay, the voltage of the IG1 relay, and the voltage of the IG2 relay are all greater than or equal to a preset voltage threshold, wherein the preset voltage threshold is, for example, 18V. If yes, determining that the function of the ON gear is normal, and if not, determining that the function of the ON gear is not realized, namely the power gear is not switched to the ON gear.
By adopting the scheme, the real vehicle test is not required for testers, the automatic test of the ON gear function is realized, the test time is shortened, and the test efficiency is improved.
FIG. 4 is a block diagram of a power supply gear functionality test system according to another exemplary embodiment. As shown in fig. 4, the system may further include: the bus communication equipment 5 is respectively connected with the upper computer 4 and the automobile body controller 3;
when the power supply gear test instruction indicates to test the OFF gear function, the bus communication device 5 is used for sending a vehicle speed signal to the vehicle body controller 3; the first board card 1 is used for sending an OFF gear function test signal to a one-key starting switch pin of the vehicle body controller 3, so that the vehicle body controller controls the first type relay, the second type relay and the third type relay to be switched OFF according to the OFF gear function test signal under the condition that the vehicle speed is smaller than a preset vehicle speed threshold; or when the power supply gear test instruction indicates to test the START gear function, the bus communication device 5 is configured to send a vehicle gear state message to the vehicle body controller 3 to indicate that the vehicle gear is in the parking gear or the neutral gear, and send an engine anti-theft authentication instruction to the vehicle body controller; the first board card 1 is used for sending a START gear function test signal to a key starting switch pin of the automobile body controller 3 and sending a starting signal to a brake pedal switch pin or a clutch pedal switch pin of the automobile body controller 3, so that the automobile body controller controls the second type of relay to be attracted and the first type of relay and the third type of relay to be disconnected according to the START gear function test signal and the starting signal under the condition that the engine anti-theft authentication passes.
In consideration of the fact that in the practical application process, when the power supply gear is switched from the ON gear to the OFF gear, whether the current vehicle speed is smaller than a preset vehicle speed threshold value needs to be judged, therefore, when the OFF gear function test is carried out, a vehicle speed signal needs to be sent to a vehicle body controller through bus communication equipment so as to simulate the real state of a vehicle. The bus communication device may be a CANoe hardware device.
The OFF-shift function test signal is an input signal required when the vehicle body controller 3 controls the OFF-shift to be turned on. Specifically, when the power supply gear is in the ON gear, a vehicle speed signal is sent through the bus communication device, and an OFF gear function test signal is sent to a key start switch pin of the vehicle body controller 3 through the first board 1, that is, a high level signal is sent to the key start switch pin through a first channel of the first board 1, so that the vehicle body controller 3 controls the first type relay (ACC relay), the second type relay (IG1 relay) and the third type relay (IG2 relay) to be turned OFF according to the high level signal under the condition that the vehicle speed is less than a preset vehicle speed threshold value. Wherein a preset vehicle speed threshold value may be stored in the vehicle body controller 3 in advance, for example, the preset vehicle speed threshold value is 5 km/h.
Then, the measurement module on the second board card 2 may be configured to measure a voltage of the ACC relay, a voltage of the IG1 relay, and a voltage of the IG2 relay, and send measurement results to the upper computer, so that the upper computer determines whether the OFF gear function is normal according to the measurement results. Specifically, the upper computer stores preset conditions for determining whether the OFF gear function is normal or not in advance. Illustratively, the preset condition is whether the voltage of the ACC relay, the voltage of the IG1 relay, and the voltage of the IG2 relay are all equal to 0V, if so, it is determined that the OFF range function is normal, and if not, it is determined that the OFF range function is abnormal.

Considering that the gear of the vehicle needs to be in the parking gear or the neutral gear when the vehicle is started, when the START gear function test is performed, a vehicle gear state message needs to be sent to the vehicle body controller 3 through the bus communication device so that the vehicle is in the parking gear or the neutral gear. Before the vehicle is started, safety certification is required between the vehicle body controller 3 and the engine controller, and when the safety certification is passed, the power supply range can be switched to the START range. It should be noted that, the process of performing the security authentication between the vehicle body controller 3 and the engine controller may refer to the scheme in the prior art, and is not described herein again.

In S501, the START gear function test signal is sent to a one-key START switch pin of the vehicle body controller 3 through the first board 1, and a START signal is sent to a brake pedal switch pin or a clutch pedal switch pin of the vehicle body controller.
In S502, a vehicle gear state message is sent to the vehicle body controller through the bus communication device to indicate that the vehicle gear is in the parking gear or the neutral gear, and an engine anti-theft authentication instruction is sent to the vehicle body controller.
In S503, it is determined whether the engine theft authentication is passed, if yes, step 504 is executed, and if no, the process returns to S503.
In S504, it is determined whether the START range function is normal, and if so, step S505 is executed, and if not, step S506 is executed.
In S505, a START range function normal command is sent to the first board 1.
In S506, it is determined that the START range function is not implemented.
The START gear function test signal is an input signal required when the vehicle body controller 3 controls START gear opening. Specifically, a START gear function test signal is sent to a key starting switch pin through a first channel of a first board card 1, that is, a high level signal is sent to the key starting switch pin, and when a vehicle is an automatic gear vehicle, a starting signal is sent to a brake pedal switch pin through a second channel of the first board card 1, that is, a low level signal is sent to the brake pedal switch pin, or when the vehicle is a manual gear vehicle, a starting signal is sent to a clutch pedal switch pin through a third channel of the first board card 1, that is, a low level signal is sent to the clutch pedal switch pin. Therefore, when the engine anti-theft authentication is passed, the vehicle body controller 3 controls the second type relay (IG1 relay) to be closed and the first type relay (ACC relay) and the third type relay (IG2 relay) to be opened according to the high level signal and the low level signal.
Then, the measurement module on the second board card 2 may be configured to measure a voltage of the ACC relay, a voltage of the IG1 relay, and a voltage of the IG2 relay, and send a measurement result to the upper computer, so that the upper computer determines whether the START gear function is normal according to the measurement result. Specifically, the upper computer stores preset conditions for determining whether the START gear function is normal or not in advance. For example, the preset condition is whether the voltage of the IG1 relay is greater than or equal to a preset voltage threshold, such as 18V, and the voltage of the ACC relay and the voltage of the IG2 relay are equal to 0V. If so, it is determined that the START range function is normal, and if not, it is determined that the START range function is not implemented, i.e., the power range is not switched to the START range.
By adopting the scheme, the real vehicle test is not required for testers, the automatic test of the START gear function is realized, the test time is shortened, and the test efficiency is improved.
It is worth to be noted that when a tester compiles a test case, a corresponding test case can be compiled for each power supply gear, a corresponding test script is generated, and the test of the power supply gear function is realized by executing each test script. The test of all power supply gear functions can be written in one test case, and the test of all power supply gear functions can be realized by executing the test case. And is not particularly limited herein.
