Problems solved by technology

This method has a high probability of detecting the failure of the charging port cover and cannot truly reflect the state of the charging connection. The state of the charging port cover is not directly related to the charging connection, and the charging port cover is often opened and closed, so it is easy There is false triggering of the signal, which causes the vehicle to fail to drive normally

Abstract

The invention provides an interlocking method for charging and driving of a vehicle, which comprises the following steps: starting and charging a vehicle when the vehicle is in an OFF gear; detecting whether the vehicle is connected with a charging gun, if the charging gun is an AC charging gun, a vehicle charger sends a charging gun connection signal to a power battery management system and an instrument; sending a charging gun connection message to a motor controller by the instrument after receiving the charging gun connection signal ; after the motor controller receives the charging gun connection signal, detecting the driving speed of the vehicle, and keeping an executive gear as a preset gear for controlling the vehicle in a non-driving state when the driving speed is equal to or smaller than the preset speed through judgment; and entering a charging mode after the powder battery management system receives the charging gun connection signal, and then keeping the charging state after a start button of the vehicle is powered on through detection. The method can be applied to AC charging electric automobiles, DC charging electric automobiles or other conductive charging electric automobiles, thereby satisfying the safety of charging and driving of the vehicle and having high efficiency and good compatibility.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to an interlocking method for charging and driving of a vehicle. Background technique [0002] With the development and popularization of electric vehicles, the safety of electric vehicles has been paid more and more attention. Especially when the vehicle is in the charging state, the reliability and safety of the connection are particularly important due to the connection with the external power grid. When charging After the connection is established, the non-driving state of the vehicle must be guaranteed, so as to avoid damage to the external charging equipment and ensure the safety of personnel; therefore, corresponding interlocking measures must be taken for the charging connection and vehicle driving. [0003] At present, another independent control module is mostly used in electric vehicles to realize similar functions by detecting the opening and closing state of ...
