[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings 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.

[0036] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present application.

[0037] The commonly used judgment method for the diesel engine remote throttle enable switch is that if the following four conditions are met at the same time: the vehicle speed is less than the calibrated minimum speed value, the engine speed is greater than the idle speed value, the remote throttle switch is turned on, and the remote throttle has no short circuit or open circuit fault, then the remote throttle function is activated. If one of the conditions is no longer met, the remote throttle function is exited.

[0038] At present, the function development of traditional diesel engine remote throttle switches is based on the A-SPICE process, which can only make safety judgments on whether there is a fault, but does not monitor the throttle switching status during actual driving. Since the remote throttle is a safety-related function, when the remote throttle is allowed to be turned on when the vehicle is in motion will have a great impact on driving safety, so the remote throttle monitoring method needs to be further improved.

[0039] Based on the above problems, the present application provides a monitoring method, device, equipment and storage medium for a remote throttle for functional safety. The key point of the invention is that the braking signal is judged when there is no functional failure in the remote throttle switch during vehicle driving, and then the use of the remote throttle switch function is more accurately controlled under two conditions: when there is a failure in the braking signal, as long as the remote throttle is turned on, the vehicle enters a safe management driving state, restricts vehicle driving and remote throttle use, and ensures driving safety. When there is no failure in the braking signal, braking can be achieved. In this state, the corresponding function of the remote throttle switch can be responded to normally, and there is no need to restrict vehicle driving and remote throttle switch functions, thereby ensuring the smoothness of the driving process.

[0040] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0041] In a first aspect, an embodiment of the present application provides a method for monitoring a remote throttle for functional safety.

[0042] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the remote throttle monitoring method for functional safety of this application. Figure 1 As shown in the figure, the monitoring method of remote throttle for functional safety includes:

[0043] S100, during the driving of the vehicle, if the remote throttle switch does not have a functional failure, determining whether the brake signal has a failure;

[0044] S210: When there is a fault in the brake signal, judging whether the vehicle needs to enter a preset safety management driving state according to whether the remote throttle switch is turned on; wherein in the safety management driving state, the vehicle engine torque output is limited and the corresponding function of the remote throttle switch is prohibited from being used;

[0045] S220: When there is no fault in the brake signal, the remote throttle switch responds normally to the corresponding function.

[0046] In this embodiment, by judging the brake signal when there is no functional failure of the remote throttle switch during vehicle driving, the use of the remote throttle switch function is more accurately controlled in both the conditions of the brake signal failure and the failure of the remote throttle switch.

[0047] Specifically, when there is a fault in the brake signal, the braking ability of the current vehicle during driving is at great risk. At this time, if the related functions of the remote throttle are still maintained, there will be great risks. Therefore, in this situation, as long as the remote throttle is turned on, this embodiment will enter the safety management driving state, restrict the vehicle driving and the use of the remote throttle, and ensure driving safety.

[0048] When there is no fault in the braking signal, the braking ability of the current vehicle driving process is normal and can brake smoothly when needed. Therefore, in this state, the corresponding functions of the remote throttle switch can be responded normally. There is no need to restrict the vehicle driving and the remote throttle switch functions, thereby ensuring the smoothness of the driving process.

[0049] Further, in one embodiment, when the brake signal fails in S210, judging whether the vehicle needs to enter a preset safety management driving state according to whether the remote throttle switch is turned on includes the following steps:

[0050] S211, if the remote throttle switch is turned on, entering the safety management driving state;

[0051] S212: If the remote throttle switch is not turned on, the safety management driving state is not entered.

[0052] Further, in one embodiment, the step S220, determining whether the brake signal has a fault, comprises the following steps:

[0053] S221. When the braking signal is bus configured, if the braking signal sent by the message is monitored, the braking signal validity flag is output; when the braking signal sent by the message is monitored to have a fault, the braking signal fault flag is output.

[0054] In this embodiment, for the vehicle situation when the brake signal is configured by the bus, it is implemented to determine whether the brake signal is faulty according to the brake signal sent by the message, thereby achieving a quick and accurate determination in this scenario.

[0055] In addition, in some other embodiments, the step S220, determining whether the brake signal has a fault, comprises the following steps:

[0056] S222. When the brake signal is hard-wired, the two brake pedal signals received after bottom-level processing are cross-checked. If the two brake pedal signals are consistent, the brake signal validity flag is output; if the two brake pedal signals are inconsistent, the brake signal fault flag is output.

[0057] In this embodiment, for the vehicle situation when the brake signal is hard-wired, whether the brake signal has a fault is determined based on the result of mutual verification between the two pedal signals, thereby achieving quick and accurate judgment of the brake signal in this scenario.

[0058] Furthermore, in one embodiment, the following steps are also included:

[0059] S110: During vehicle driving, if there is a functional failure in the remote throttle switch, the vehicle is controlled to enter the safety management driving state.

[0060] When the vehicle is in motion, it is necessary to first determine whether the remote throttle switch has a functional fault, such as whether the remote throttle is short-circuited or open-circuited. When a related fault is detected, the vehicle is directly controlled to perform safe driving management.

[0061] Furthermore, in one embodiment, during the driving of the vehicle, if the remote throttle switch does not have a functional failure, before determining whether the brake signal has a failure, the following steps are included:

[0062] S010, obtaining a vehicle speed signal;

[0063] S020: If the vehicle speed signal is greater than a preset limit value and no braking signal is obtained, it is determined that the vehicle is in a driving process.

[0064] In this embodiment, by acquiring the vehicle speed signal, when the vehicle speed is greater than the corresponding limit value, it is triggered to determine whether the brake signal is obtained. When it is determined that the brake signal is not obtained, it means that the vehicle is in the driving process. Then, the relevant remote throttle switch function can be monitored and controlled during the driving process.

[0065] In addition, the design of the solutions in the above embodiments is based on the E-GAS architecture, with the existing remote throttle function as the level 1 functional layer, and a remote throttle function monitoring mechanism is designed at the level 2 monitoring layer, that is, the vehicle driving status, braking signal, and remote throttle switch signal are monitored at the level 2 layer.

[0066] Finally, by judging the brake signal when there is no functional failure of the remote throttle switch during vehicle driving, the use of the remote throttle switch function can be more accurately controlled in both the case of a brake signal failure and a non-failure condition. When there is a brake signal failure, as long as the remote throttle is turned on, the vehicle enters the safe management driving state, restricting the vehicle driving and the use of the remote throttle to ensure driving safety. When there is no brake signal failure, braking can be achieved. In this state, the corresponding function of the remote throttle switch can be responded normally, and there is no need to restrict the vehicle driving and the remote throttle switch function, ensuring the smoothness of the driving process. When there is a functional failure of the remote throttle switch, the vehicle will be directly controlled to enter the safe management driving state of the vehicle to ensure that the remote throttle switch function will not be triggered unexpectedly, resulting in driving safety.

[0067] In a second aspect, an embodiment of the present application also provides a remote throttle monitoring device for functional safety.

[0068] In one embodiment, referring to Figure 2 , Figure 2 This is a functional module diagram of an embodiment of a remote throttle monitoring device for functional safety of the present application.

[0071] Further, in one embodiment, when the control module executes: when the brake signal fails, judging whether the vehicle needs to enter a preset safety management driving state according to whether the remote throttle switch is turned on, the control module specifically includes the following steps:

[0072] If the remote throttle switch is turned on, the safety management driving state is entered;

[0073] If the remote throttle switch is not turned on, the safety management driving state will not be entered.

[0074] Further, in one embodiment, when the monitoring module performs the step of determining whether the braking signal has a fault, the following steps are included:

[0075] When the brake signal is bus configured, if the brake signal sent by the message is monitored, the brake signal validity flag is output; when the brake signal sent by the message is monitored to have a fault, the brake signal fault flag is output.

[0076] Further, in one embodiment, the monitoring module performs: the step of determining whether the braking signal has a fault, including the following steps:

[0077] When the brake signal is hard-wired, the two brake pedal signals received after bottom-level processing are cross-checked. If the two brake pedal signals are consistent, the brake signal validity flag is output; if the two brake pedal signals are inconsistent, the brake signal fault flag is output.

[0078] Further, in one embodiment, the monitoring module, before executing: during the vehicle driving process, if the remote throttle switch does not have a functional failure, determining whether the brake signal has a failure, includes the following steps:

[0079] Obtaining a vehicle speed signal;

[0080] If the vehicle speed signal is greater than a preset limit value and no braking signal is obtained, it is determined that the vehicle is in a driving process.

[0081] Furthermore, in one embodiment, the control module is further configured to execute: during vehicle driving, if there is a functional failure in the remote throttle switch, controlling the vehicle to enter the safety management driving state.
