Abstract:
Embodiments of the present invention provide a method and an apparatus for determining a vehicle acceleration, which are used to eliminate an interference element in data of an accelerometer, and correct accelerometer data that is obtained after interference is eliminated, into acceleration data of a vehicle. The method includes: acquiring original acceleration data measured by the accelerometer in a running process of the vehicle; eliminating, according to the acquired original acceleration data, interference generated by gravity on the original acceleration data, and interference generated, on the original acceleration data, by a change of an angle of the accelerometer caused by moving of the accelerometer relative to the vehicle; and determining acceleration data of the vehicle in the running process according to original acceleration data that is obtained after interference is eliminated.
