Problems solved by technology
[0006] Such a conventional vacuum brake has a problem that the suction pressure of the vehicle engine must be supplied to the vacuum booster in order to create a vacuum, thereby reducing fuel efficiency
In addition, conventional vacuum brakes also have a problem that the engine must be continuously driven in order to create a vacuum even when the vehicle is stopped.
[0007] In addition, in the case of fuel cell vehicles and electric vehicles, there is no engine, so the existing vacuum brake cannot be applied to amplify the driver's pedaling force when braking the vehicle, and in the case of hybrid vehicles, when When the vehicle is stopped, the idle stop function must be implemented to improve fuel efficiency, so the introduction of hydraulic brakes is required

An electric integrated brake device according to an embodiment of the present invention includes a master cylinder that generates a hydraulic pressure based on the operation of a pedal, a pedal simulator that provides a pedal stepping force to the pedal based on the hydraulic pressure, a motor that is driven based on the displacement of the pedal, a pump that applies a braking pressure to a wheel cylinder arranged at a wheel side of the vehicle based on the operation of the motor, a valve block that includes a plurality of solenoid valves for opening and closing the flow of oil moving among the master cylinder, the pedal simulator, the pump, and the wheel cylinder, and an ECU (electronic control unit) that controls the motor and the valve block, wherein the master cylinder, the pedal simulator, the motor, the pump, the valve block, and the ECU are integrated into a single structure.
Description
technical field [0001] The present invention relates to an electric brake device, more particularly, to such an electric brake device, which can reduce the overall size and weight of the brake device to reduce manufacturing costs, and can improve the In-house mountability for easy layout design. Background technique [0002] In recent years, in order to improve fuel efficiency and reduce emissions, research and development of hybrid vehicles, fuel cell vehicles, electric vehicles, and the like have been actively performed. [0003] In these vehicles, a braking system, that is, a braking device of a vehicle is basically installed, wherein the braking device of a vehicle refers to a device for stopping a running vehicle or reducing the speed of a running vehicle. [0004] As examples of a typical braking device of a vehicle, a vacuum brake that generates a braking force using a suction pressure of a vehicle engine and a hydraulic brake that generates a braking force using hyd...
