Abstract

The invention provides a method and a system for adjusting the fuel injection amount according to the axial force of a pulley, and relates to the field of vehicles. The invention firstly detects the axial force of the pulley in the generator, and then executes the fuel injection restriction strategy when judging that the pulley is abnormal according to the axial force. In the present invention, since the change of the axial force of the generator pulley is approximately the change of the torque of the pulley of the generator, the change of the torque of the pulley can be known by detecting the axial force of the pulley of the generator. , to ensure vehicle safety.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method and system for adjusting fuel injection quantity according to pulley axial force. Background technique [0002] The generator pulley transmits the kinetic energy of the crankshaft pulley to the generator through the belt. During the rotation of the generator, the rotor cuts the magnetic field lines to generate direct current. Therefore, the generator pulley is an important part of the generator. However, the torque of the generator pulley is an important technical parameter. If the torque of the generator pulley cannot be detected well, it will cause torque attenuation, which will cause the pulley to fall off, and the torque detection problem will lead to normal driving. [0003] In the prior art, it is impossible to accurately detect the torque of the generator pulley, so it is impossible to give a reminder when the pulley is abnormal and to ensure the normal operation of the wh...
