Problems solved by technology

However, in the actual driving process, it often occurs that the motor has been ignited and started, but due to negligent driving, the gear is not engaged or the driver accidentally steps on the electric door pedal, etc., the ignition status is only indicated by the light on and off. The safety system of the state of the motor and whether the motor / or battery fails cannot completely prevent accidents from happening

Embodiment Construction

[0028] The present invention is described in detail below in conjunction with accompanying drawing:

[0029] figure 2 It is a system schematic diagram of an embodiment of the present invention. In this embodiment, the fault signal is displayed by a red fault light. figure 2 The startup control strategy for the system shown is as follows figure 1 The control shown in the block diagram is as follows:

[0030] The electric vehicle is powered on, and the ignition operation is performed.

[0031] Whether the power-on of the vehicle controller is normal, if it is normal, the vehicle controller enters the self-test state, the system is initialized, and the system parameters are configured. If abnormal is 'No', the red fault light of the combined instrument will be on.

[0032] The vehicle controller judges whether the seat position switch is closed, and if it is closed, proceed to the next operation; if it is 'No', the red fault light of the combination instrument is on. Do no...

Abstract

The invention provides a false-start-prevention control policy for an electric vehicle. The false-start-prevention control policy for the electric vehicle comprises a vehicle control unit power-on detection step, a component state detection step, a motor driving system working state detection step, a sensor detection step and an electric vehicle idle state time control step, wherein the component to be detected comprises a seat position switch, a brake pedal switch, a gear switch and a switch pedal; working state parameters of a motor driving system comprise motor rotation speed, power, voltage, current, temperature and a working mode. The false-start-prevention control policy for the electric vehicle has the advantages that the false-start-prevention control policy and method for the electric vehicle judge the states of a vehicle control unit, the seat position switch, the brake pedal switch, the gear switch, the switch pedal, a charging switch and a motor driving system, and judge whether the automobile vehicle is at a safety start state; the damage from all false-start operations caused by external factors is blocked, accidents are prevented, and the safety and the reliability of the vehicle are greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle anti-misstarting control strategy. Background technique [0002] Electric cars are very different from traditional cars, and their potential safety hazards are also different from traditional cars. When a traditional car is started, the engine will vibrate obviously, but when an electric car starts, there is no obvious prompt sound. Instruments are generally used to display the starting status, and most electric cars on the market are easy to start. The driver can drive the electric vehicle to walk. List as the Chinese Invention Patent Announcement No. CN102490625B utilizes the change of indicator light to show ignition status, motor running status and motor / or battery whether break down. However, in the actual driving process, it often occurs that the motor has been ignited and started, but due to negligent driving, the gear is not engaged or the...
