[0015] The following discussion pertains to various embodiments of this disclosure. While one or more of these embodiments may be preferred, the disclosed embodiments should not be construed as or otherwise intended to limit the scope of this disclosure (including the claims). Furthermore, those skilled in the art will understand that the following description has broad application, and the discussion of any embodiment is merely illustrative and not intended to imply that the scope of this disclosure (including the claims) is limited to that embodiment.

[0016] As described, vehicles (such as cars, trucks, SUVs, crossovers, minivans, boats, aircraft, all-terrain vehicles, recreational vehicles, or other suitable forms of transportation) typically include various systems, such as steering systems and / or other suitable systems (e.g., braking systems, propulsion systems, etc.). Steering systems may include EPS systems, SbW steering systems, hydraulic steering systems, or other suitable steering systems. Such systems of a vehicle typically control various aspects of the vehicle's steering (e.g., including providing steering assistance to the vehicle's operator, controlling the vehicle's steerable wheels, etc.), vehicle propulsion, vehicle braking, etc.

[0017] Typically, systems that provide application conditioning (which may be referred to as or include global output limiting) ensure adequate protection of components in a quality management (QM) environment by validating the operational integrity of the components and vehicle systems under development. For example, components, such as those classified as QM (Quality Management) in vehicle systems below the minimum ASIL rating of ISO 26262, used in higher safety-critical systems like ASIL D steering systems, can be used in higher safety systems (ASILa, B, C, or D) if the safety indicators of the QM component output are validated using the global output limiter described herein. Such systems providing global output limiting can be applied to various vehicle systems, such as EPS steering systems, SbW steering systems, etc., and can be utilized across different chassis and / or brake-by-wire applications if the normal operating window or condition and the failure operating window or condition are known.

[0018] Therefore, it may be desirable to have systems and methods configured to provide software application conditioning (such as those described herein). In some embodiments, the systems and methods described herein can be configured to ensure the integrity and safety of motor torque commands under various conditions by using multiple checks and limits. The systems and methods described herein can be configured for use in any chassis application, provided that normal and fault conditions are defined.

[0019] The system and method described herein can be configured to operate in four phases: 1) signal value checking and limiting, 2) signal rate checking and limiting, 3) error flag checking, and 4) mixing. First, the system and method can be configured to verify that the signal value is within a predefined safety threshold by using a saturation block and a timer to ensure that the signal value does not exceed set limits. If the signal exceeds these limits, a “signal value error flag” is set. The upper and lower limits for the saturation block and timer checks can be derived from the same calibration values ​​named “QMCmdLimHi” and “QMCmdLimLo”.

[0020] Alternatively, the systems and methods described herein can be configured to monitor the rate of signal change to prevent sudden and unsafe fluctuations. For example, a previous signal command can then be used to calculate the signal rate, which can undergo three checks: an unstable rate threshold that will scale the signal value and increment the P / N counter, a stable signal threshold that will saturate the rate and increment the P / N counter, and a zero-rate check that enables a timer. If any of these checks is detected, an error flag for the signal rate is set.

[0021] Next, the system and method can be configured to send a signal indicating that an error has been detected if any error flag is active. For example, the function could subsequently check all error flags, and if one or more error flags are set, a DTC (diagnostic trouble code) can be set, where parameter bytes are used to identify which flag(s) are set. The system and method described herein can be configured to set and output the “GlbLmrFltDetd” (Global Limiter Error Detected) flag to warn any downstream component that an error has been identified and is being modified in its output.

[0022] The system and method can be configured to apply a mixing factor supplied to mix the final output signal from the "QM-limited input signal" to the "input signal". The system and method can be configured to apply a final saturation block to ensure that the QM-limited input signal, or the input signal, is within the hard limits of the system and method described herein.

[0023] Figure 3A and 3BA flowchart of an application conditioning process based on the principles of this disclosure is generally shown. For example, the application conditioning process may include receiving an input signal from the quality management (QM) environment at point 204 and checking whether the signal exceeds a predefined numerical limit. If the signal does not exceed the signal value limit, at point 206, the signal rate is calculated based on the previous value and three signal threshold checks are performed. If the signal does exceed the signal value limit, at point 208, the signal is saturated back within a safe boundary. At point 210, a timer is started. Alternatively, if the signal does not exceed the signal value limit, the time at point 210 is reset.

[0024] At 212, the process determines if the timer has exceeded a threshold. If the timer exceeds the threshold, at 252, the process sets a torque command error. If the timer does not exceed the threshold, the process continues at 206. At 206, the signal rate is calculated based on the previous value and three signal threshold checks are performed. For example, at 214, the process determines if the signal rate exceeds a stability threshold. If the signal rate does exceed the threshold, at 220, the process limits the signal rate. At 222, the process increments the positive / negative (P / N) counter. At 242, if the P / N counter exceeds the threshold, the process sets a signal rate error. If the P / N counter does not exceed the threshold, the process returns to 204. If the signal rate does not exceed the threshold at 214, the process decrements the counter at 222 and returns to 204.

[0025] At 216, the procedure determines if the signal rate is equal to 0. If the procedure determines that the signal rate is equal to 0, it starts a timer at 224. If the signal rate is not equal to 0, the procedure stops the timer and returns to 204. At 246, if the timer exceeds the threshold, the procedure determines that the signal rate was set incorrectly.

[0026] At 218, the process determines whether the signal rate exceeds an instability threshold. If the signal rate exceeds the instability threshold, the process adjusts the signal command at 246.

[0027] At 248, the process increments the P / N counter. At 250, if the P / N counter exceeds the threshold, the process sets the signal rate incorrectly. If the signal rate does not exceed the instability threshold at 216, the process decrements the counter at 250 and returns to 204.

[0028] At 252, the process receives error input data from 254 and application error input from 256 (e.g., and / or from 212, 242, 246, and 250). The process determines whether an error has been set. If no error is set, the process terminates. If at least one error is set, at 258, the process sets a global limiter error at 266. The process sets the DTC via debug information. At 260, the process receives backup command input from 268. The process mixes the command signal with the command input. At 262, the process provides final saturation. At 264, the process outputs the final output command limit signal.

[0029] Failure to maintain a stable signal can trigger an error. The application conditioning process can monitor different types of errors, such as those related to signal values, rate thresholds, or external inputs from the QM environment. If any error is detected, the application conditioning process sets a "Global Limiter Error," which involves setting a DTC (Distributed Troubleshooting Control) via error debugging information. The application conditioning process can also mix client signals with "Backup Command Input" signals and then limit output commands to ensure system integrity and security.
