[0056] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] This application is explained by taking a hybrid vehicle including two energy sources, an engine and a motor, as an example.

[0058] In order to facilitate the understanding of those skilled in the art, the present application provides a torque monitoring system. Figure 1 The torque monitoring system includes: a controller 100 , a motor controller 200 connected to the controller 100 , and an engine controller 300 connected to the controller 100 .

[0059] This application provides a torque monitoring method embodiment 1, which is applied to Figure 1 The controller 100 in the torque monitoring system is shown. Figure 2 , the torque control method comprises the following steps:

[0060] Step S201: monitor the actual torque of the hybrid vehicle to obtain a first monitoring result.

[0061] See also Figure 3 , the software layer of the controller includes a function layer and a monitoring layer, then step S201 specifically includes steps S2011 to S2013:

[0062] Step S2011: The monitoring layer obtains the operating signal of the hybrid vehicle, and uses the operating signal to calculate the actual torque threshold.

[0063] The monitoring layer can obtain the operating signals of the hybrid vehicle, such as the accelerator pedal amplitude and operating mode; the operating modes may include: cruise control, adaptive cruise control, automatic parking, brake energy recovery and limp home, etc.

[0064] The monitoring layer obtains the operation signal of the hybrid vehicle and can calculate a reference actual torque, and add a preset offset to the reference actual torque to obtain the actual torque threshold. The calculation of the reference torque is a mature technology, and the preset offset can be pre-set according to different vehicle models, and this application does not limit it.

[0065] Step S2012: The monitoring layer obtains the actual response torque of the motor and the actual response torque of the engine, and calculates the actual torque output by the engine and the motor to the wheel end according to the current gear state.

[0066] The monitoring layer obtains the actual response torque of the motor from the motor controller through the CAN bus, and obtains the actual response torque of the engine from the engine controller through the CAN bus. The monitoring layer then calculates the actual torque output to the wheel end (wheel) of the hybrid vehicle under the action of the engine and the motor according to the current gear state of the hybrid vehicle. The actual torque is the actual torque of the hybrid vehicle under the action of the hybrid power source.

[0067] Step S2013: The monitoring layer compares the actual torque with the actual torque threshold to obtain a first monitoring result.

[0068] The monitoring layer compares the actual torque with the actual torque threshold to obtain a first monitoring result. The first monitoring result may be: the actual torque is greater than the actual torque threshold, or the actual torque is not greater than the actual torque threshold.

[0069] Step S202: monitor the required torque of the hybrid vehicle to obtain a second monitoring result.

[0070] See also Figure 3 , the software layer of the controller includes a function layer and a monitoring layer, then step S202 specifically includes steps S2021 to S2024:

[0071] Step S2021: The monitoring layer obtains the operating signal of the hybrid vehicle, and uses the operating signal to calculate the required torque threshold.

[0072] The monitoring layer can obtain the operating signals of the hybrid vehicle, such as the accelerator pedal amplitude and operating mode; the operating modes may include: cruise control, adaptive cruise control, automatic parking, brake energy recovery and limp home, etc.

[0073] The monitoring layer obtains the operation signal of the hybrid vehicle to calculate a base demand torque, and adds a preset offset to the base demand torque to obtain the demand torque threshold. The calculation of the base demand torque is a mature technology, and the preset offset can be pre-set according to different vehicle models, and this application does not limit it.

[0074] Step S2022: the functional layer calculates the required torque according to the operation signal of the hybrid vehicle;

[0075] The functional layer can also obtain the operating signal of the hybrid vehicle and calculate the required torque based on the operating signal. The calculation of the required torque is a mature technology and will not be described in detail here.

[0076] Step S2023: The monitoring layer obtains the required torque from the functional layer.

[0077] Step S2024: Compare the required torque with the required torque threshold to obtain a second monitoring result.

[0078] The monitoring layer compares the required torque with the required torque threshold to obtain a second monitoring result. The second monitoring result may be: the required torque is greater than the required torque threshold, or the required torque is not greater than the required torque threshold.

[0079] Step S203: Determine a control instruction for controlling the hybrid electric vehicle based on the first monitoring result and the second monitoring result.

[0080] Four situations are obtained by integrating the first monitoring result and the second monitoring result. The four situations and the control instructions of the hybrid vehicle in the four situations are described below.

[0081] The first case: when the required torque is greater than a required torque threshold and the actual torque is greater than an actual torque threshold, resetting the controller.

[0082] The prior art only uses the required torque as a basis for judgment. When the required torque is greater than the required torque threshold, the safety mechanism is triggered to control the hybrid vehicle to enter a safe state. This embodiment no longer controls the hybrid vehicle to enter a safe state, but resets the controller to restore the controller to an initial state.

[0083] The second situation: when the required torque is greater than the required torque threshold and the actual torque is not greater than the actual torque threshold, the normal operation of the hybrid vehicle is maintained;

[0084] The prior art only uses the required torque as a basis for judgment. When the required torque is greater than the required torque threshold, the safety mechanism will be triggered to control the hybrid vehicle to enter a safe state. However, in this case, the actual torque does not exceed the actual torque threshold, that is, the hybrid vehicle does not need to enter a safe state. The present application can well prevent the hybrid vehicle from mistakenly entering a safe state, thereby improving reliability.

[0085] The third case: when the required torque is not greater than the required torque threshold and the actual torque is greater than the actual torque threshold, the controller is controlled to trigger the safety mechanism;

[0086] The prior art only uses the required torque as the basis for judgment, and the safety mechanism will not be triggered when the required torque is not greater than the required torque threshold. However, in this case, the actual torque may exceed the actual torque threshold. Therefore, the present application will control the hybrid vehicle to enter a safe state. That is, the present application can well ensure that the hybrid vehicle enters a safe state and improve reliability.

[0087] The fourth situation: when the required torque is not greater than the required torque threshold and the actual torque is not greater than the actual torque threshold, the normal operation of the hybrid vehicle is maintained.

[0088] Through the above technical features, it can be found that the present application has the following beneficial effects:

[0089] The present application can monitor the required torque and actual torque of a hybrid vehicle simultaneously. Compared with the prior art which monitors the required torque alone, the torque of the hybrid vehicle can be monitored from both the required torque and the actual torque, thereby improving the reliability of the hybrid vehicle.

[0090] The present application can maintain the normal operation of the hybrid vehicle and prevent the hybrid vehicle from entering a safe state by mistake when the demand torque is greater than the demand torque threshold but the actual torque is not greater than the actual torque threshold; although the demand torque is not greater than the demand torque threshold, when the actual torque is greater than the actual torque threshold, the control controller triggers the safety mechanism, thereby improving the reliability of the hybrid vehicle.

[0091] This application provides a torque monitoring method embodiment 2, which is applied to Figure 1 The controller 100 in the torque monitoring system is shown. Figure 4 , the torque control method comprises the following steps:

[0092] Step S401: Acquire the operation signal of the hybrid vehicle.

[0093] Step S402: Calculate the required torque and the required torque threshold based on the operating signal.

[0094] Step S403: Calculate the actual torque and the actual torque threshold based on the operating signal.

[0095] Step S404: Determine whether the actual torque is greater than the actual torque threshold; if not, proceed to step S405; if yes, proceed to step S406.

[0096] Step S405: Maintain normal operation of the hybrid vehicle.

[0097] Step S406: Determine whether the required torque is greater than the required torque threshold, if so, proceed to step S407, if not, proceed to step S408.

[0098] Step S407: Reset the controller.

[0099] Step S408: Control the controller to trigger the safety mechanism.
