Description

[0001] A BRAKING SYSTEM

[0002] Technical Field

[0003] The present invention relates to a system which enables electric vehicles to be stopped completely with the help of an electric motor and without the need to press the brake pedal after the vehicle is slowed down below a certain speed by regenerative braking (slowing down the kinetic energy of a moving vehicle by converting it into a form that can be used immediately or stored until it is needed) or by slowing down according to gravity as the driver stops pressing the accelerator pedal completely or partially.

[0004] Background of the Invention

[0005] Currently, in motor vehicles, stopping the vehicle in motion requires reducing the speed of the vehicle by taking the foot off the accelerator and pressing the brake pedal, and pressing the clutch brake all the way to the end. Currently, when there is a need to press the brake pedal there may be problems such as some vehicle users exerting extra pedal effort or confusing the brake pedal with the accelerator pedal, which may cause serious problems.

[0006] For this reason, considering the studies and deficiencies included in the current technique, it is understood that there is a need for a system that enables vehicles to be stopped completely with the help of an electric motor and without the need for drivers to press the brake pedal when vehicles fall below a certain speed and provides driving comfort with a single pedal.

[0007] The Chinese patent document no. CN114312328A, an application included in the state of the art, discloses a system which provides braking assistance when driving a vehicle with one pedal. In the system included in the said invention, a controller operates the friction brake to stop the vehicle in response to the release of the accelerator pedal, and when the brake pedal is not engaged and the speed of the vehicle is less than a certain threshold, the controller enables the vehicle to be stopped by means of an electric motor in response to the release of the accelerator pedal and the speed being below a certain threshold.

[0008] Summary of the Invention

[0009] An object of the present invention is to realize a system which enables electric vehicles to be stopped completely with the help of an electric motor and without the need to press the brake pedal after the vehicle is slowed down below a certain speed by regenerative braking (slowing down the kinetic energy of a moving vehicle by converting it into a form that can be used immediately or stored until it is needed) or by slowing down according to gravity as the driver stops pressing the accelerator pedal completely or partially.

[0010] Another object of the present invention is to realize a system which enables the vehicle to be stopped without the need for the driver to press the brake pedal by guaranteeing that the vehicle stops at a fixed distance each time provided that the vehicle is below a certain speed value; and enables the electrical energy to be used efficiently if the time of stopping the vehicle is longer than the determined time by holding the vehicle via the electric motor for a predetermined period of time and then by hydraulic brakes if the respective time is exceeded after the vehicle is stopped.
