Detection and remediation of an instability condition in a vehicle-trailer system

A stability monitoring system for detecting an instability condition in a moving vehicle-trailer system, the stability monitoring system comprising:

• a processor;
• and
• a memory communicably coupled to the processor and storing a stability evaluation module including computer-readable instructions that when executed by the processor cause the processor to:
• if a measured value of at least one stability evaluation parameter satisfies an associated predetermined evaluation parameter condition, determine an accumulation value of the at least one stability evaluation parameter;
• if the accumulation value satisfies a first predetermined accumulation condition, set the accumulation value equal to a first limit value;
• and
• if the accumulation value satisfies a second predetermined accumulation condition after being set to the first limit value, control operation of the vehicle to deactivate or prevent activation of a lane tracing assist system of the vehicle.

A computer-implemented method for detecting an instability condition in a moving vehicle-trailer system, the method comprising steps of:

• determining a total amount of time over a predetermined time period that a measured value of at least one stability evaluation parameter satisfied an associated predetermined condition;
• determining if the total amount of time exceeds a significant proportion of the predetermined time period, within a range of 10%-30% (inclusive) of the predetermined time period;
• if the total amount of time exceeds the significant proportion of the predetermined time period, controlling operation of the vehicle to deactivate a lane tracing assist system of the vehicle;
• and
• if the total amount of time does not exceed the significant proportion of the predetermined time period, controlling operation of the vehicle to activate the lane tracing assist system.
