Electric vehicle speed-regulating device and control method thereof

Abstract

The invention publishes an electric vehicle speed-regulating device and a control method thereof. The device is characterized in that a pressure sensor is connected with an electric vehicle controller the control unit of which is formed by using a singlechip as a core; the pressure sensor is horizontally installed between the spongy cushion and the protecting surface of an electric vehicle driving seat, and the output end thereof is connected with the input end of the control unit in the electric vehicle controller. The control method thereof is characterized in that whether a driver sits on the driving seat or not is detected through the pressure sensor; when an electric vehicle is pushed, a rotating handle is rotated to regulate the speed within a low speed range; in the normal driving process of the electric vehicle, when the electric vehicle is braked and stopped, the body leaves the driving seat of the electric vehicle, and the rotating handle is not loosened; and when the rotating handle is loosened, the speed of the electric vehicle is still zero. The invention improves the braking safety of the electric vehicle when encountering an emergency in driving and overcomes the potential safety hazard brought by the speed of the electric vehicle exceeding the walking speed of a person when the person pushes the electric vehicle to walk with speed by rotating the rotating handle.

Description

technical field [0001] The invention relates to the technical field of driving safety of electric vehicles, in particular to an electric vehicle speed regulating device and a control method thereof. Background technique [0002] Existing electric vehicle (electric bicycle, electric motorcycle, electric tricycle) all is to adopt the Hall handle to regulate speed, and when the handle rotates, the driving speed is accelerated or decelerated. In the normal driving process, you can accelerate or decelerate by turning the handle. When you encounter an emergency stop, you can quickly decelerate and stop driving by braking, but people often do not release the handle while braking. Release the brake lever, and the electric car quickly turns to normal driving; the second is that the mind is too nervous to reflect on unexpected events. When the body is in the driving seat, it is feasible not to let go of the handle, but when people encounter an emergency, they often leave the driver's...

AI Technical Summary

Problems solved by technology

When the body is in the driving seat, it is feasible not to let go of the handle, but when people encounter an emergency, they often leave the driver's seat of the electric car while braking and stand on the ground with both feet. When the handle is turned on and the brake handle is released, the electric vehicle will run faster than the normal speed (because the person leaves the body, the electric vehicle is lighter), and it is easy for the vehicle to overturn and cause traffic accidents. If the speed of the electric vehicle is zero at this time , there will be no traffic accidents

Although there is a patent No. CN201046748Y "multi-gear electric vehicle speed control handle" report, it can be switched to low-speed driving gear when the road condition is poor or there are many pedestrians and vehicles, but it needs manual adjustment, which cannot solve the problem of emergency stop in sudden situations

At the same time, the current electric vehicle has the problem that it cannot automatically limit the speed when pushing it, because when the electric vehicle is walking, people often turn the handle to push it at a high speed in order to save effort. If you are not careful, it is easy to slow down the speed of the electric vehicle Adjusted to exceed a person's walking speed, thereby dragging the person down
