【Abstract】With the rapid development of theautomotive industry,cars have been widely popularized as daily means of transportation,andthedemandforvehicledriving safetyperformance hasemergedaccordingly.Among them,the brakingfunction and parking safetyof vehicles are the most importantsafety performance indicators.When the electronic gearshifting systemof theentirevehiclemalfunctions,driversoftenfail tonoticeit.Moreover,duetothefailure toidentify the fault in time,theydo not take active braking measures, which can easilylead to the vehicle roling back and surging forward,therebycausing damage to thelives and propertyof drivers andthepublic.This paperproposesabraking control schemefor parkinggearfaults.Afterdetectingfaultsinthevehicle's electronicshiftsystem,the transmisioncontroler determines the vehicle'ssafebraking stateand automaticalyparks the vehicle in this state tocontrol itto maintain braking.Thisavoids the problemofthe vehicleroling back and sudden acceleration whenthedriver does not take active braking measures. It has greatly protected the safety of drivers and the public.
