Electric control method on blade electric vehicle and blade electric vehicle

Abstract

The invention provides an electric control method on a blade electric vehicle and the blade electric vehicle. The method includes the steps of when the vehicle is completely powered off, judging whether the vehicle has a powering request or not, if yes, controlling a main relay of the vehicle to be turned on, supplying power to a motor controller, a battery management system and a low-voltage power utilization device through a power battery to conduct low-voltage powering, after low-voltage powering is completed, judging whether a brake signal and a vehicle startup switch signal can be detected or not and whether high-voltage powering conditions are met or not, if the brake signal and the vehicle startup switch signal are detected and the high-voltage powering conditions are met, sending ahigh-voltage powering instruction to the battery management system through a whole-vehicle controller, and sending a motor enabling instruction to the motor controller to conduct high-voltage powering. The signal interaction between all controllers in the powering process of the blade electric vehicle and the actions which should be executed after instruction signals are received are explicitly stipulated, and therefore the reliability and safety of the powering process of the blade electric vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a pure electric vehicle power-on control method and the pure electric vehicle. Background technique [0002] The energy crisis and environmental pollution have made traditional vehicles face increasingly serious challenges. New energy vehicles have become the current and future development trend, and pure electric vehicles occupy an important position in new energy vehicles. However, due to the short development time of pure electric vehicles, the technology is not mature enough, the accumulated design experience is insufficient, and the power-on process and power-on conditions of pure electric vehicles are not considered comprehensively enough, resulting in the frequent failure of power-on of the vehicle, which has caused serious damage to the driver. Great trouble. [0003] The current power-on logic of pure electric vehicles is too simple, there is no perfect definition of...

However, due to the short development time of pure electric vehicles, the technology is not mature enough, the accumulated design experience is insufficient, and the power-on process and power-on conditions of pure electric vehicles are not considered comprehensively enough, resulting in the frequent failure of power-on of the vehicle, which has caused serious damage to the driver. great trouble

[0003] The current power-on logic of pure electric vehicles is too simple, there is no perfect definition of the power-on process, and the signal interaction between the controllers involved in the power-on process, the state switching of each controller itself, and the process of power-on are not fully considered. Time required, the time required for the controlled object to respond to the controller command, if the vehicle condition is slightly different from the ideal condition, there will be a problem that the power cannot be turned on, and even the control logic of the whole vehicle will fall into chaos, resulting in unpredictable consequences

That is, the safety and reliability of the current pure electric vehicle power-on process are low, which affects the driver's driving experience and driving safety.
