A brake device for a vehicle includes: a brake pedal having a pedal portion and a lever portion that rotates about a rotation axis when the pedal portion is operated; a housing that rotatably supports the lever portion; and a plate member configured to generate a reaction force with respect to the lever portion in response to a stroke amount of the brake pedal. The plate member has a longitudinal surface defined by a side extending in a longitudinal direction of the plate member and a side extending in a width direction of the plate member. The longitudinal surface is arranged so as to face the lever portion. When the pedal portion is operated, the plate member is bent to generate the reaction force.

A brake device includes: a brake pedal including a pedal and a lever that rotates about a rotation axis when the pedal is operated; a housing that rotatably supports the lever; a reaction force generator that generates a reaction force to the lever in accordance with a stroke amount of the brake pedal by receiving a force from the lever when the brake pedal is operated; a deformation member including a deformation portion that is deformed by a force received from the lever when the brake pedal is operated in a state where the reaction force generated by the reaction force generator is generated; and a stroke sensor that outputs a signal corresponding to the stroke amount and outputs a value indicating that operation of the brake pedal is abnormal and instructing execution of control for stopping a vehicle when the deformation portion is deformed.

An electronic mechanical brake system and a vehicle. The electronic mechanical brake system includes a brake pedal, an electronic brake mechanism, a mechanical brake mechanism, a brake, and a switch mechanism with a first state and a second state. The electronic brake mechanism includes a controller and an electronic signal sensor. The controller, the electronic signal sensor, and the brake are electrically connected.

A brake booster assembly having a brake booster body and a pushrod as well as a pushrod-pedal coupler are provided. The pushrod travels along a pushrod axis when being pushed. The brake booster assembly includes a pushrod-pedal coupler. The pushrod-pedal coupler comprises a pushrod-attachment end arranged on the pushrod and defining a longitudinal axis parallel to the pushrod axis. A pedal-attachment end is configured to be attached to a pedal and having a pedal pivot axis around which the pedal pivots when being pushed. The pedal pivot axis extends across the longitudinal axis. A coupler hinge is arranged between the pushrod-attachment end and the pedal-attachment end and connects the pushrod-attachment end with the pedal-attachment end. The coupler hinge has a coupler hinge axis that extends across the longitudinal axis and the pedal pivot axis. The pedal pivot axis and the coupler hinge axis are offset along the longitudinal axis.

A retrofit pneumatic circuit complements an existing factory braking system to preserve the original function of the driver's foot pedal while also adding the ability for a computer to actuate the brakes separately and independently. In the event where both the primary and secondary drivers are actuating the brakes at any time, the braking force applied is the maximum of the two. In the preferred approach, a shuttle valve is connected between a primary proportional valve and a copy of that proportional valve. Directional control valves are also included to isolate both the input and the output portions of the secondary circuit in order to enforce positive shutdown of computer control. One directional valve blocks a supply pressure to prevent bleeding of the system in any situation where pressure is requested when computer control is supposed to be disabled. A second directional valve vents any built-up pressure to the atmosphere, so that any residual pressure does not actuate the brakes after computer control is disabled.
