Claim 2:
3. The method according to claim 2, wherein the step of, according to the matching relation between the speed parameter and the predetermined first parameter table, determining the first proportionality coefficient and the first differential coefficient that correspond to the speed parameter comprises:
determining a first vehicle-speed fuzzy subset that matches with the speed parameter;
determining a first speed end value and a second speed end value of the first vehicle-speed fuzzy subset;
determining a first-end-value proportionality coefficient and a first-end-value differential coefficient in the first parameter table that correspond to the first speed end value;
determining a second-end-value proportionality coefficient and a second-end-value differential coefficient in the first parameter table that correspond to the second speed end value;
determining a first membership coefficient, comprising: dividing a difference between the first speed end value and the speed parameter by a difference between the second speed end value and the first speed end value, to determine the first membership coefficient;
determining a second membership coefficient, comprising: dividing a difference between the second speed end value and the speed parameter by the difference between the second speed end value and the first speed end value, to determine the second membership coefficient;
determining the first proportionality coefficient, comprising: dividing a sum of a product between the first membership coefficient and the first-end-value proportionality coefficient and a product between the second membership coefficient and the second-end-value proportionality coefficient by a sum of the first membership coefficient and the second membership coefficient, to determine the first proportionality coefficient; and
determining the first differential coefficient, comprising: dividing a sum of a product between the first membership coefficient and the first-end-value differential coefficient and a product between the second membership coefficient and the second-end-value differential coefficient by a sum of the first membership coefficient and the second membership coefficient, to determine the first differential coefficient.
