Description

Vehicle-mounted module debugging system and vehicle

Technical Field

The utility model relates to a general car technical field. Particularly, the utility model relates to an on-vehicle module debug system.

Background

A large number of on-board electronic modules are used in a vehicle, and Micro Control Units (MCUs) among the electronic modules are diverse, and can be developed or acquired in full operating states of their chips basically only by using software, licenses and debuggers provided by their semiconductor manufacturers. However, these manufacturers provide development tools that are not available on already assembled vehicles.

Therefore, in the development of vehicles, various environmental tests are generally performed on electronic modules to be mounted to the vehicles first, and then the entire vehicle on which the electronic modules are mounted is placed in various environmentally-harsh areas and tested to find out possible problems. Since a developer cannot directly debug an electronic module that has been mounted on a vehicle, the electronic module itself that has a problem can be analyzed only in a laboratory, and the environmental situation at the time of the problem can be reproduced by simulation.

However, due to the complex driving environment of the tested vehicle, the numerous electronic devices inside the vehicle, various spatial signal interferences and many unknown situations, many situations in the test cannot be simulated by a laboratory. Therefore, some problems that can only occur when the entire vehicle is in an actual working condition cannot be debugged for the electronic module in the laboratory. At present, although the real-time condition of a vehicle can be recorded through an automobile diagnosis technology, the root cause of the problem cannot be found according to recorded information in many cases; moreover, the information is relatively simple for developers and is not helpful to the maintenance and upgrade of the vehicle software.

Detailed Description

In the present description, the present invention is described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The present invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. The embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Terms such as "comprising" and "comprises" mean that, in addition to having elements which are directly and unequivocally recited in the description and claims, the technical solution of the present invention does not exclude other elements which are not directly or unequivocally recited. Terms such as "first" and "second" do not denote an order of the elements in time, space, size, etc., but rather are used to distinguish one element from another.

In prior art fig. 1, the component connection relationship when using a conventional debugging method is shown. The computer 11 is connected to a commissioning device 12, the commissioning device 12 being connected to an on-board module 13 to be commissioned. The computer 11 may be, but is not limited to, a desktop computer, a laptop computer, a portable computing device, a tablet computer, etc., as long as it can be used for a technician to perform control operation on the debugging apparatus 12 and display information for debugging to the technician, and in response to the information, the technician can perform debugging by using corresponding operation. The commissioning apparatus 12 is typically provided by a corresponding semiconductor manufacturer that provides the in-vehicle electronic module, and needs to be used together with software and licenses provided by the manufacturer. The on-board module 13 is shown in fig. 1 as an on-board Micro Control Unit (MCU), but it may be any electronic module that requires commissioning, such as various entertainment, networking, security, control modules, etc. that are common on vehicles.

Referring now to fig. 2, fig. 2 illustrates a schematic block diagram of an on-board module commissioning system 100 according to an embodiment of an aspect of the present invention. The on-board module commissioning system 100 includes the commissioning device 12 described above in fig. 1. The system 100 further comprises a first communication means 14 connected to the commissioning device 12 and a second communication means 15 connected to the on-board module 13 to be commissioned. As shown in fig. 2, the first communication device 14 and the second communication device 15 are connected to each other, and are configured to transmit signals between the commissioning device 12 and the in-vehicle module 13. In one embodiment, one or both of the first communication device 14 and the second communication device 15 is a bluetooth low energy module (BLE). In this case, the first communication device 14 and the second communication device 15 are wirelessly connected and communicate by bluetooth. However, the first communication apparatus 14 and the second communication apparatus 15 may be wirelessly connected by a technology such as 2.4 GHz. Generally, the commissioning device 12 and the on-board module 13 receive and generate level signals (for example, "high" level and "low" level), and the wirelessly transmitted signals have different forms according to different wireless connection modes, so that during transmission, the format of the signals needs to be selectively converted. The conversion may be achieved by configuring the communication means 14, 15 accordingly.

In one embodiment, the first communication device 14 may be designed as a user terminal, i.e. the first communication device is not provided with the vehicle, but is provided for convenient use by a technician who is to perform the commissioning. On the one hand, the first communication device 14 is connected to the commissioning device 12 (for example, through a commissioning interface dedicated to a bluetooth connection or other wireless connection on the commissioning device 12), and converts a wireless signal received by the first communication device into an IO port level signal to be sent to the commissioning device 12, so that the signal received by the commissioning device 12 from the first communication device 14 has the same level form as the signal in the case where the commissioning device 12 is directly connected to the on-board module 13. In one embodiment, the first communication device 14 detects the action level signal of the IO port of the debugging device 12 in real time, and then transmits the content and the timing of the IO port action level signal through a signal (e.g., a bluetooth signal).

In the case where the first and second communication devices 14 and 15 are bluetooth modules, the wireless signals are bluetooth signals, and the conversion from the wireless bluetooth signals to the level signals may be performed using, for example, an IO port of a bluetooth low energy chip CC2640 of texas instruments. The computer 11 may then acquire a feedback signal of the on-board module 13 via the commissioning device 12 and perform a commissioning operation of the on-board module 13 by means of the specific developed software and the license in response to the feedback signal. On the other hand, the first communication device 14 may convert the debugging signal from the debugging person received via the debugging device 12 into a form of a desired wireless signal and then transmit the signal, thereby realizing the debugging operation (e.g., single step, breakpoint, jump, address inquiry, etc.) for the in-vehicle module 13. Thereby, the first communication means 14 receives the commissioning signal from the commissioning device 12 to the on-board module 13 and sends a feedback signal from the on-board module 13 to the commissioning device 12. Accordingly, the second communication device 15 performs the corresponding sending and receiving actions, as described below.

The second communication device 15 may be designed on the vehicle side, i.e. the second communication device 15 may be integrated in the vehicle, for example in an on-board electronic module. In one embodiment, the second communication module 15 may be a bluetooth chip in the in-vehicle module 13. In another embodiment, the IO port of the on-board module 13, which is originally used for connecting with the commissioning device 12, may be connected with the second communication device 15. The second communication device 15 may be configured to connect with the in-vehicle module 13. For example, the second communication device 15 may be connected with a debugging interface of the in-vehicle module 13 to obtain the development right. In one embodiment, the second communication device 15 may be directly connected to the JTAG interface of the on-board module 13 to be debugged through its IO port to obtain the highest development authority of the on-board module 13. As shown in table 1, a schematic table of the universal debug interface of the in-vehicle module 13 is shown. On one hand, the second communication device 15 receives the signal from the first communication device 14 at the user side, converts the signal into an IO level signal (i.e., a debugging signal) suitable for the on-board module 13, and sends the IO level signal to the on-board module 13, so as to achieve the effect of debugging the on-board module 13. On the other hand, the second communication device 15 receives a feedback signal (e.g., a level signal) generated by the in-vehicle module 13 in response to the debug signal from the in-vehicle module 13, and converts the feedback signal into a signal form suitable for transmission between the first communication device 14 and the second communication device 15 for transmission. Thereby, the second communication device 15 receives the feedback signal from the on-board module 13 to the commissioning device 12 and transmits the feedback signal from the commissioning device 12 to the on-board module 13.

The first communication device 14 and the second communication device 15 can debug and troubleshoot the on-board module 13 when the on-board module 13 cannot be directly connected and debugged on the vehicle. Further, by the conversion of the signal format (for example, the conversion of the wireless signal into the level signal), the connection and communication of the first and second communication devices 14, 15 with the debugging device 12 and the in-vehicle module 13, respectively, can be realized.

In one embodiment, for the first and second communication devices 14, 15 connected by wireless, the second communication device 15 is enabled in response to the unlock signal. That is, the second communication device 15 may be configured to be normally in a locked state (e.g., disabled state, powered off state, etc.), and unlocked (e.g., enabled, powered on, etc.) only when a proper unlock signal is received (e.g., an unlock signal with a proper key communicated through a vehicle CAN (controller area network)). Then, the second communication device 15 scans the spatial signal as, for example, a bluetooth chip, and establishes communication with the first communication device 14.

For example, in the case where the second communication device 15 is a bluetooth module, after unlocking the vehicle, a separate key may be set for unlocking the bluetooth function. The key may be configured individually for each vehicle and may be set to require authorization by the host factory to unlock the function. The power supply system of the bluetooth module can be set to be switched on and off through an IO port of the vehicle-mounted module 13, when a correct instruction is input, the vehicle-mounted module 13 pulls up the level of the IO port, and then the bluetooth power supply module is switched on. The related functions of the bluetooth module can be set in the bluetooth module when leaving the factory, and can also be written in later according to the requirement. By unlocking the second communication device 15 by using the unlocking signal to enable the second communication device 15, the vehicle-mounted module 13 can be prevented from being maliciously tampered to a great extent, so that the safety of the vehicle is improved, and the safety control of debugging operation of the vehicle-mounted electronic module by using wireless connection is realized.

In one embodiment, system 100 may also include intermediate communication devices (e.g., 16 and 17 shown in FIG. 2). The intermediate communication device may be disposed between the first communication device 14 and the second communication device 15 in the order of the communication links and configured to facilitate communication between the first communication device 14 and the second communication device 15. For example, where the first communication device 14 and the second communication device 15 are wirelessly communicating using bluetooth or 2.4GHz technologies, the communication distance is typically limited to tens of meters, at which time an intermediate communication device may be employed to facilitate communication over greater distances (e.g., kilometers, hundreds of kilometers, thousands of kilometers, or even globally) between the first communication device 14 and the second communication device 15.

To this end, the intermediate communication means may be two remote communication devices, and the communication distance between the two remote communication devices is greater than the communication distance between the first communication means 14 and the second communication means 15. In one embodiment, the intermediate communication device may be two electronic devices with cellular data transfer functionality, such as a smartphone, a tablet, or a laptop. In particular, the electronic device on the vehicle side, which is part of the intermediate communication means, near the second communication means 15, may typically be a mobile phone, a portable computer, a tablet computer, a laptop computer, etc., since the vehicle is often in motion and its location is difficult to determine, the use of a mobile device may make the function of the in-vehicle module commissioning system 100 more convenient. Besides the mobile device, the electronic device at the user end, which is a part of the intermediate communication device and is close to the first communication device 14, may be a fixed electronic device such as a desktop computer, because the user of the on-board module commissioning system 100 is mainly a technician performing the commissioning, who has a fixed office, and thus the fixed electronic device is also applicable.

In the case of using a mobile phone as the relay, the connections of the respective components in the in-vehicle module debugging system 100 are as follows: the on-board module 13 includes the second communication device 15 or is connected to the second communication device 15, the second communication device 15 is connected to the vehicle-side mobile phone 17, the vehicle-side mobile phone 17 is connected to the user-side mobile phone 16 and performs remote communication, the user-side mobile phone 16 is connected to the first communication device 14, the first communication device 14 is connected to the debugging device 12, and finally the debugging device 12 is connected to the various debugging equipment computers 11 that can be used by the debugging personnel as described above, thereby completing the remote debugging work. Cellular data communication such as 4G and 5G between the vehicle-side mobile phone 17 and the user-side mobile phone 16, bluetooth communication between the vehicle-side mobile phone 17 and the second communication device 15, and bluetooth communication between the user-side mobile phone 16 and the first communication device 14 can be performed by a mobile phone APP operation. This problem can be alleviated by avoiding repeated signaling while in operation, as signaling through the handset as a relay can result in signal delay and redundancy, resulting in a slow debugging process in this mode.

The remote debugging device can solve the problem of remote debugging through the intermediate communication device, uses equipment with a remote communication function as transfer equipment to transfer signals between the first communication device and the second communication device, and can realize remote debugging spanning kilometers, hundreds of kilometers, thousands of kilometers and even the whole world.

According to still another aspect of the present invention, there is provided a vehicle having a second communication device 15 loaded thereon, the second communication device 15 being configured to: to the on-board module 13; to the first communication device 14; and signals are transmitted between the commissioning device 12 and the on-board module 13.

In a vehicle according to an embodiment of the present invention, one or both of the first communication device 14 and the second communication device 15 is a bluetooth low energy module (BLE); the second communication device 15 is connected with a debugging interface of the vehicle-mounted module 13 to obtain development permission; the second communication device 15 is enabled in response to the unlock signal; and the signals comprise commissioning signals from the commissioning device 12 to the on-board module 13 and feedback signals from the on-board module 13 to the commissioning device 12.

According to the utility model discloses a vehicle still includes: a second intermediate communication device 17 disposed between the first communication device 14 and the second communication device 15 and configured to facilitate communication between the first communication device 14 and the second communication device 15, wherein the second intermediate communication device 17 is a long-distance communication apparatus, and a communication distance between the second intermediate communication device 17 and the first intermediate communication device 16 is larger than a communication distance between the first communication device 14 and the second communication device 15.

The second communication device 15 in the vehicle has communication with the first communication device 14 outside the vehicle and other functions, thereby enabling commissioning of an in-vehicle module that has been installed to the vehicle without additionally wiring with the in-vehicle module 13.

According to the utility model discloses an on-vehicle module debug system mainly can be applied to the development process of vehicle and the maintenance process of vehicle. The vehicle-mounted electronic module can be directly debugged and analyzed under the condition of not damaging the vehicle or disassembling the vehicle-mounted module, and the real information of the vehicle-mounted electronic module can be obtained.
