Description

Fault diagnosis system for two-wheeled vehicle and control method thereof

The subject matter described herein generally relates to a fault diagnosis system for a two-wheeled vehicle and a control method thereof.

Traditionally, onboard diagnostic systems/fault diagnostic systems have been used in vehicles to provide fuel system-related or emissions-related information to consumers. However, over the years, as the number of electrical and electronic systems in vehicles has increased, and the overall number of complex systems and subsystems has increased, on-board diagnostic systems in vehicles have become Vehicle failure related information to consumers and has become widely used in all types of vehicles including hybrid vehicles, especially to facilitate the vehicle operator and service engineer/serviceman to easily identify the failure and facilitate the vehicle Convenient maintenance and monitoring of the control system. Therefore, the on-board diagnostic system has become synonymous with fault diagnosis.

Conventional fault diagnosis systems function to provide fault indication to the vehicle operator by emitting/flashing LED lights when a fault is detected, or when a fault in the vehicle is detected, by A malfunction alarm/beep alert to warn the vehicle operator. However, the role of LED lights and fault alarms is not so useful, especially when the vehicle arrives at a maintenance depot for maintenance, where the maintenance engineer will need to use a diagnostic tool for retrieving fault related information, And the information is then displayed on a computer. Therefore, the use of a computer is a must. Furthermore, the diagnostic The use of the equipment also requires the maintenance engineer to refer to the standard operating procedure manual from time to time to facilitate the diagnosis of the fault. Consequently, the use of conventional fault diagnosis systems has proven cumbersome.

In particular, the fault diagnosis system utilizes a CANopen master station for analyzing and storing fault information, which is then displayed on the fault diagnosis interface. However, the storage of fault information for real-time analysis of the information requires the use of a high-performance processor in the control unit, which has proven to be expensive. Furthermore, the use of multiple modules also results in an overall increase in the complexity of the fault diagnosis system. Therefore, it is difficult to use such a fault diagnosis system in a small vehicle such as a hybrid/electric two-wheeled vehicle.

The vehicle 10 as described above includes a fault diagnosis system 100 as shown in FIG. 2 . FIG. 2 is a schematic block diagram showing a fault diagnosis system according to an embodiment of the present invention. A fault diagnosis system according to the present invention comprises an electronic control unit 101, a device display cluster 102 communicatively connected to the electronic control unit 101, and a plurality of vehicle sensors operatively connected to the electronic control unit 101, It includes a throttle position sensor 103a, one or more Hall sensors 103b, a current sensor 103c, a motor temperature sensor 103d, and the like. Furthermore, the electronic control unit 101 is powered by a battery 104 which has its own controller, and the controller forms part of the battery management system that transmits signals to the Electronic control unit 101 and receive signals from the electronic control unit 101 . Information processed by a first microcontroller in the electronic control unit is passed to the device display cluster 102 via controller area network (CAN) communication. For example, the first microcontroller processes a plurality of vehicle-related information including vehicle fault-related information based on input provided by the plurality of vehicle sensors, and communicates the information to the device display cluster. In this embodiment, the device display cluster 102 includes a second microcontroller for processing the information transmitted by the electronic control unit 101 .

In accordance with a feature of the present invention, the equipment display cluster 102 is configured to display vehicle fault-related information to the vehicle operator/a serviceman. In particular, the equipment display cluster 102 is configured to display information related to the vehicle malfunction only upon receipt of a predetermined display command.

Figures 3 and 4 depict the steps involved in a method of operation of the electronic control unit 101 and the equipment display cluster 102 for achieving the display of vehicle fault-related information. The flow chart 200 in FIG. 3 represents the electronic control unit 101 for detecting in the vehicle A fault and the steps to signal the fault to the operation of the vehicle operator. The flowchart 300 in FIG. 4 represents the steps in the operation of the device display cluster 102 in achieving the display of vehicle fault information.

As can be seen in FIG. 3, in a first step of its operation, in a condition in which the ignition switch is on, the electronic control unit is at block 201 based on receiving from the plurality of vehicle sensors information to determine whether any faults were initially detected in a stationary condition of the vehicle. If a fault is detected/existed in block 202, the electronic control unit 101 transmits a fault signal to the equipment display cluster 102. If no fault is detected/existed, the electronic control unit further waits for a throttle input, and further determines in block 203 whether the received throttle input is greater than a preset threshold throttle input. If the received throttle input is greater than the preset threshold throttle input, then the electronic control unit allows the vehicle to be powered in the existing drive mode, and further determines at block 204 the speed of the vehicle during travel Is there any fault detected/existing in the condition. In a situation where the fault is detected in the condition of a vehicle traveling, the electronic control unit transmits a fault signal to the equipment display cluster at block 205, which then generates a set at the equipment display cluster A flashing actuation of the fault indicator in the . Afterwards, the electronic control unit also determines at block 206 whether the vehicle is likely to travel with an alternate driving mode. In a situation where the vehicle cannot be operated with an alternate drive mode, the fault indicator will continue to glow red, thereby indicating to the vehicle operator that the vehicle is due to the presence of one or more a malfunction and cannot be used. However, if the electronic control unit determines that it is possible for the vehicle to operate in an alternative drive mode, it will automatically cause a change in the drive mode and allow the vehicle to operate.

For example, in situations where the electronic control unit 101 detects a fault in the vehicle's battery and thus in an EV mode of operation of the vehicle, the electronic control unit determines that the vehicle is in an alternate drive mode whether the operation in is possible. If the electronic control unit determines that operation of the vehicle in an alternative drive mode such as a single engine mode is possible, it causes a change in the drive mode to cause the vehicle to operate in a drive mode such as a single engine mode Alternative to Engine Mode in the drive mode.

However, in a situation where operation of the vehicle in an alternate driving mode is also impossible, thus making repair of the vehicle necessary, the fault diagnosis system according to the present invention functions to assist a serviceman to easily identify One or more faults in the vehicle, and thereby easily correcting the one or more faults. In particular, the fault diagnosis system 100 according to the present invention functions to display information related to the vehicle fault in a readable format. In other words, the fault diagnosis system functions to display a fault message in order to facilitate easy understanding of the fault in the vehicle by the serviceman. The fault message can be a short text briefly indicating the fault, or it can be a number, the corresponding explanation of which is provided in a maintenance manual in the form of a look-up table, which can be used by the maintenance service personnel for reference.

The fault diagnosis system according to the present invention uses the equipment display cluster as a fault diagnosis interface for displaying the fault message. In other words, the device display cluster 102 is configured to display the fault message. The flowchart 300 depicted in FIG. 4 depicts steps in a method involving the operation of the device display cluster for achieving display of vehicle fault-related information.

The device display cluster 102 of the fault diagnosis system 100 is configured to display the fault message only when a predetermined display command is received. The flowchart 300 in FIG. 4 shows the steps involved in providing the preset display command. For example, in a situation where the vehicle arrives at a service station for service, and when the ignition is turned on, if any fault is detected according to the steps described in FIG. 3, the electronic The control unit transmits vehicle fault-related information to the equipment display cluster via CAN communication. Therefore, when a fault is detected, the electronic control unit transmits a fault signal to the equipment display cluster, and when the second microcontroller in the equipment display cluster receives the fault signal at block 301, it At block 302, a flashing actuation of a fault display indicator disposed in the display cluster of the device is caused. Furthermore, the second microcontroller checks whether there is the preset display command. For example, in this embodiment, the second microcontroller determines the Whether a hazard warning switch of the vehicle is switched on. If the second microcontroller detects that the hazard warning switch is turned on, the electronic control unit further determines in block 304 whether a button such as an output boost button has been pressed for more than 10 seconds. Thus, a preset display command according to the present invention involves selection of a hazard warning switch followed by long pressing of a button of the vehicle for a preset time interval. Therefore, upon receiving the above-mentioned preset display command, the second microcontroller in the device display cluster is tied at block 305 so that the fault message is displayed in a readable form. The output boost button according to the invention acts as a means for starting the vehicle. In particular, the power boost button acts as a safety feature in the vehicle, which helps to ensure that the vehicle can only be powered if the power boost button and a brake handle are selected together at the same time.

According to a feature of the present invention, the fault message is presented in a readable format as shown in Figures 5a and 5b. In particular, the equipment display cluster is configured to display the number of detected faults (A), a short text of the detected faults (B), and a corresponding fault number (C) for each detected fault ). For example, Figure 5a shows the fault message "d tPS" for a condition in which the throttle wire or the throttle position sensor becomes defective. When this condition is detected by the electronic control unit 101, it disables the vehicle. In particular, such a fault condition corresponding to the above fault message may occur due to a fault in the throttle wire, or in the throttle position sensor, thus when only the ignition switch is turned on , may cause this throttle input to initially be greater than 60%. The initial throttle input itself, when very high, may cause an accident when the vehicle operator unknowingly rotates the throttle without knowing that there is a fault in the throttle wire, or in the throttle position sensor. Therefore, it becomes important to detect such a malfunction and stop the vehicle at the initial stage immediately after the ignition is switched on. When the above conditions are detected, the electronic control unit communicates to the equipment display cluster via CAN communication. As discussed in the preceding paragraph, the device display cluster then, upon receipt of the default display command, represents the short text of the fault message "d tPS". A corresponding fault number 01 is also displayed next to the short text. the repair An attendant can easily identify the fault by mapping the fault number and the short text using a look-up table in a maintenance manual that can be located in the maintenance station. Therefore, the service attendant can easily repair the fault in the vehicle, and quickly complete the repair of the vehicle.

Figure 5b shows another example of a fault message that can be displayed on the display panel of the device. "ryopen" refers to a condition in which one of the phases is not connected to the electronic control unit. The above conditions may occur due to any of the following conditions listed below, such as when a phase conductor connector has a loose contact, or a motor phase coil in the motor has burned out, or Is when one of the motor phase connector wires in the wiring harness burns out due to heat.

In a situation where multiple faults are detected by the electronic control unit, the equipment display cluster shows the number of faults and a short text and fault number corresponding to each detected fault. Especially in situations where multiple faults are detected, the number of faults, the short text of each fault and the fault number are flashed one after the other, with a short time interval between each flashing .

According to a feature of the invention, data regarding information related to the vehicle malfunction is transmitted by the electronic control unit to the equipment display cluster. For example, in one embodiment, eight bytes (64 bits) of data may be transmitted to the display cluster by the electronic control unit in one packet. In other words, by assigning a dedicated bit to each fault, at least 64 individual faults can be transmitted. Therefore, the number of faults is identified by the second microcontroller counting the number of "1"s in the 64-bit data, and the number of faults is displayed. In another embodiment, depending on the complexity of the system and the number of failures, the number of packets used may be increased. Furthermore, the second microcontroller retrieves the corresponding short text and the corresponding fault code from a reference table stored in the second microcontroller, and the reference table is then assigned to each a fault prepared by the bit number.

It is apparent from the above description that the fault diagnosis system functions to facilitate easy understanding of faults in the vehicle using the device display cluster as the fault diagnosis interface, thereby functioning as a It is a cost-effective means of fault identification in small vehicles such as two-wheeled electric/hybrid vehicles.
