Abstract
A system/method of resetting the value of a control parameter (GCWCP) indicative of vehicular gross combined weight and determined as a filtered/averaged value, to a predetermined default value upon sensing vehicle operating conditions (50% GCWCP<GCWTEST or 200% GCWCP>GCWTEST)deemed indicative of a change in vehicle loading. A vehicle automated system, such as an automated mechanical transmission system, is controlled as a function of the value of the control parameter.
Claims10
A control system for an automated vehicle system on a vehicle, said vehicle system including a controller for controlling said vehicle system as a function of input signals and predetermined logic rules, said control system comprising:
- means for continuously determining current vehicular gross combined weight upon the occurrence of determination enabling conditions comprising:
- means for determining a revised control parameter value (GCWCP) indicative of current gross combined weight as a filtered average of a current and a predetermined first plurality of previous determinations of current vehicular gross combined weight;
- means for determining a revised test value (GCWTEST) of current vehicle gross combined weight as a filtered average of a current and a predetermined second plurality of previous determinations of current vehicular gross combined weight, said first plurality at least twice as great as said second plurality of determinations;
- means for comparing said control parameter value to said test value;
- means for setting said control parameter value to a predetermined default value independent of said control parameter value or said test value if said control parameter value is less than a first percentage of saia test value or greater than a second percentage of said test value;
- and
- means for causing said vehicle system to be controlled as a function of said control parameter value.
A method for controlling an automated vehicle system on a vehicle, said vehicle system including a controller for controlling said vehicle system as a function of input signals and predetermined logic rules, said method comprising the steps of:
- continuously determining current vehicular gross combined weight upon the occurrence of determination enabling conditions comprising:
- determining a revised control parameter value (GCWCP) indicative of current gross combined weight as a filtered average of a current and a predetermined first plurality of previous determinations of current vehicular gross combined weight;
- determining a revised test value (GCWTEST) of current vehicle gross combined weight as a filtered average of a current and a predetermined second plurality of previous determinations of current vehicular gross combined weight, said first plurality at least twice as great as said second plurality of determinations;
- comparing said control parameter value to said test value;
- setting said control parameter value to a predetermined default value independent of said control parameter value or said test value if said control parameter value is less than a first percentage of saia test value or greater than a second percentage of said test value;
- and
- causing said vehicle system to be controlled as a function of said control parameter value.
