A detection and control device for preventing misloading of electric vehicles

Abstract

The invention relates to the technical field of electric vehicle safety protection, in particular to a detection and control device for preventing error loading of an electric vehicle. When a person pushes the electric vehicle, if the situations that a Hall turning handle is turned to accelerate, and the turning handle backward pulling force is increased occur, error loading can be determined; in order to avoid vehicle flying, when a speed detection unit and a turning handle backward pulling force detection unit successively detect signals of two changes, a brake system can be started through a main control chip; when the person pushes the electric vehicle, if only the situation that the Hall turning handle is turned to accelerate occurs, and the situation that the turning handle backward pulling force is increased does not occur, a driver intends on turning the Hall turning handle to obtain proper speed, for example, on a difficult road, the Hall turning handle is properly turned for acceleration to realize a force-assisting effect. Therefore, when only the speed detection unit detects a speed increase signal, the speed limit protection is started through the main control chip to avoid accidents.

Description

technical field [0001] The invention relates to the technical field of safety protection of electric vehicles, in particular to a detection and control device for preventing misloading of electric vehicles. Background technique [0002] Electric vehicles are small, flexible, and energy-saving, making them still play an irreplaceable role in this era of popular cars. Whether it is for automobiles or electric vehicles, while bringing convenience and speed to people, driving safety is always a proposition that cannot be ignored. For most electric vehicle users, they will have such an experience. When the user is riding normally, they can obtain the driving speed they want by turning the Hall handle on the electric vehicle. The larger the rotation range, the faster the driving speed. Fast, this is very convenient, however, it also hides a danger. When the user needs to get off the car to push the electric car in some special situations, due to the user's negligence, it is very ...

Problems solved by technology

For most electric vehicle users, they will have such an experience. When the user is riding normally, they can obtain the driving speed they want by turning the Hall handle on the electric vehicle. The larger the rotation range, the faster the driving speed. Fast, this is very convenient, however, it also hides a danger. When the user needs to get off the car to push the electric car in some special situations, due to the user's negligence, it is very likely to turn the handle, causing the electric car to accelerate suddenly , in this emergency situation, especially for female users, the most likely result is car crash and death

This is obviously not the result we want to see, but there is still no electric vehicle that can eliminate this potential danger on the market.
