Electro-Magnetic Parking Brake System for Electric Vehicles 2019-26-0119

Regular vehicle has the advantage of Engine resistance even when it is not fired, hence vehicle roll back will not happen. This is not the case for Electric vehicles, which uses an electric motor, which does not have any resistance offered to wheels that prevent vehicle roll back on gradient. This leads to increased load on hydraulic brakes due to absence of engine inertia. Hence, there is a need for a low cost and reliable automatic braking system which can help in holding the vehicle and assists the driver during launch in case he need s to stop at a gradient. An Electromagnetic brake (EM brake) system can be used as a solution for the above-mentioned requirement. EM brake can provide hill hold and hill assist effect in addition automatic parking brake application when the vehicle is turned-off. This system will assist anyone who need to halt the vehicle at a gradient and then relaunch without much struggle. During emergency conditions, if the EM brake is nor disengaging automatically, a manual brake release system can be used to disengage the brake so that the vehicle can be towed away to the service center. This feature will be an added safety feature for Electric vehicles.
