Threshold value.If so, then execution step 7052, if it is not, then reminding driver's current driving not meet fuel-economy
Property require.
Step 7052, become the lamp time and become the lamp time next time according to the last of the traffic lights, determine institute
Change lamp time last time is stated with the difference of current time, the change lamp time next time and current change lamp time
Difference.
Change lamp described in this programme, refers to from red light and is changed into green light, or is changed into red light from green light.
Step 7053, judge whether to have in two differences at least one less than preset time threshold：If so, then
Driver is not reminded；If it is not, then reminding driver's current driving not meet fuel economy requirement.
Specifically, if last become the lamp time with the difference of current time less than preset time threshold, illustrate
Now driver may need to bring to a halt, if become the difference of lamp time and current time next time less than presetting
Between threshold value, then illustrate that now driver may need acceleration to break through, under both of these case, can allow compared with
Low fuel economy scoring, now need not remind driver.
Or, as long as current fuel economy scoring is not too low, need not all remind driver；If
Fuel economy scoring is too low, even in the case where lamp is become, it is also possible to which driver is reminded.
