The invention discloses a vehicle outdoor environment temperature correction method and device. The vehicle outdoor environment temperature correction method includes the following steps of: obtaining a first cooling liquid temperature value; obtaining a first outdoor environment temperature correction value, wherein the first outdoor environment temperature correction value is an outdoor environment temperature correction value at the last flameout of a vehicle; obtaining a first parking time duration threshold value and a second parking time duration threshold value according to the first cooling liquid temperature value and the first outdoor environment temperature correction value; reading a current sampling value of a temperature sensor; obtaining the parking time duration of the vehicle; judging whether the parking time duration is between the first parking time duration threshold value and the second parking time duration threshold value; and obtaining a current outdoor environment temperature correction value according to the first outdoor environment temperature correction value, the current sampling value and an engine heat effect value if the parking time duration is between the first parking time duration threshold value and the second parking time duration threshold value. With the vehicle outdoor environment temperature correction method and device of the invention adopted, the problem of poor accuracy when a temperature sensor is utilized to obtain the outdoor environment temperature of a vehicle can be solved.
