Problems solved by technology

[0002] New energy vehicles that use electric drive usually have faults such as high or low voltage of the monomer or the total voltage, high battery temperature, etc., because these faults are high-level faults, and the current electric drive vehicles, in key systems such as batteries or motors When a high-level fault occurs, the high-voltage power-off operation is usually used, causing the vehicle to fail to drive

Abstract

The invention provides a method and apparatus for controlling an electric driving vehicle. The method includes determining whether the electric driving vehicle is under a braking state, employing a full throttle priority control strategy to control the electric driving vehicle if the electric driving vehicle is not under a braking state. The method allows the electric driving vehicle to advance or retreat according to the input of a driver even if said high-level faults occur, and ensures the personal safety.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a control method and device for an electrically driven vehicle. Background technique [0002] New energy vehicles that use electric drive usually have faults such as high or low voltage of the monomer or the total voltage, high battery temperature, etc., because these faults are high-level faults, and the current electric drive vehicles, in key systems such as batteries or motors When a high-level fault occurs, the high-voltage power-off operation is usually used, causing the vehicle to fail to drive. [0003] However, if these failures occur and the vehicle is in a crisis state such as a railway crossing or a tsunami attack, what the driver needs at this time is not to protect the integrity of the vehicle, but to save his own life. Drive forward or reverse based on driver input. Contents of the invention [0004] The present invention aims to solve one of th...
