The present invention relates to an electronic control unit (ECU) structure of a brake system, and has an ECU board that is arranged, as an addition, in a symmetric or asymmetric structure in order to form redundancy in preparation for the breakdown of an ECU, and has sensors that are also arranged for implementation of the redundancy, and thus the brake system can be operated even if a part of the ECU breaks down.

The present invention relates to an electronic control unit (ECU) structure of a brake system. An ECU of a brake system, according to the present invention, has a redundancy configuration in which a first control unit, a first cover, and a second control unit are sequentially stacked so that the first control unit and the second control unit are spatially separated by means of the first cover, and thus the second control unit can perform the function of the first control unit without being influenced when the first control unit malfunctions.

A foldable pedal apparatus of a vehicle may include a pedal pad, in which in a manual driving mode situation where a driver directly drives the vehicle, the pedal pad projects into an internal space of the vehicle and is popped up to be exposed toward the driver, whereas in an autonomous driving mode situation where the driver does not directly drive the vehicle, the pedal pad is inserted into a protection cover and is in a hide state where the exposure of the pedal pad toward the driver side is blocked, so that in the hide state of the pedal pad, a prominent internal design of the vehicle may be secured, and when the pedal pad is changed from the hide state to a popup state, the pedal pad is popped up through a small-sized panel hole formed on a footrest panel, and thus a high-tech image may be maximized.

A control system for a vehicle may include a brake assembly having a brake actuator that operates brakes to apply braking forces to wheels of the vehicle when actuated, a propulsion system having a propulsion actuator operable to apply propulsive forces to at least some of the wheels when actuated, a hand-operated actuator, and processing circuitry operably coupled to the hand-operated actuator, the propulsion system, and the brake assembly to apply a balancing brake force to balance the propulsive forces generated based on actuation of the propulsion actuator while the vehicle is below a threshold speed and both the hand-operated actuator is actuated and the brake actuator is not actuated, and release the braking forces when the hand-operated actuator is released.

A brake apparatus, for electrically driven motor vehicles, includes a traction motor at an axle of a vehicle, which traction motor is used both as drive motor and as brake system with recuperation of brake energy, a first piston-cylinder unit, which is actuatable by means of an actuating device, in particular brake pedal, a second piston-cylinder unit, which is actuatable by means of an electromotive drive and a non-hydraulic gearing apparatus, in particular spindle drive. The piston-cylinder units are connected via hydraulic connecting lines to wheel brakes of the motor vehicle. A pressure chamber of the first piston-cylinder unit is connected to two wheel brakes of a vehicle axle, and a pressure chamber of the second piston-cylinder unit is connected to a vehicle axle for active brake force feedback control and recuperation control in interaction with the traction motor.

The present disclosure includes a system, method, and device related to controlling brakes of a towed vehicle. A brake controller system includes a brake controller that controls the brakes of a towed vehicle based on acceleration. The brake controller is in communication with a speed sensor. The speed sensor determines the speed of a towing vehicle or a towed vehicle. The brake controller automatically sets a gain or boost based on the speed and acceleration.

Disclosed is a vehicle attitude control system for controlling the attitude of a vehicle in which a road wheel suspension is configured such that a roll axis of a vehicle body inclines downwardly in a forward direction. The vehicle attitude control system includes: a lateral acceleration sensor operable to detect a lateral acceleration; a brake actuator operable to apply a braking force; and a brake control device operable, based on a traveling state of the vehicle, to generate the braking force, wherein the brake control device is configured to execute vehicle attitude control of applying, to an inner rear road wheel, a larger braking force when the lateral acceleration of the vehicle is relatively large than when the lateral acceleration is relatively small, thereby suppressing uplift of an inner rear portion of the vehicle body.

A vehicle brake system includes a vehicle brake device and a hydraulic pressure generation unit. The vehicle brake device includes: a brake pedal that has a pedal portion, and a lever portion rotating about a rotation axis in response to the pedal portion being operated; a stroke sensor that outputs a signal based on a stroke amount of the brake pedal; a housing that rotatably supports the lever portion; and a reaction force generation portion that generates a reaction force applied on the lever portion based on the stroke amount. The hydraulic pressure generation unit generates a hydraulic pressure for braking a vehicle.

A vehicle brake device includes a brake pedal having a pedal part and a lever part rotatable about a rotational shaft according to an operation of the pedal part, a housing rotatably supporting the lever part and being located in a vehicle compartment of a vehicle and on a partition wall that separates an outside of the vehicle compartment and an inside of the vehicle compartment, and a reaction force generator connected to the housing and the lever part and configured to generate a reaction force on the lever part in accordance with a stroke amount of the brake pedal.

A brake device for a vehicle includes: a brake pedal having a pedal part and a lever part that rotates about a rotation shaft when the pedal part is operated; a housing that rotatably supports the lever part; a reaction force generator connected to the housing and the lever part to generate a reaction force against the lever part according to a stroke amount of the brake pedal; and a stopper configured to stop the lever part by being in contact with the lever part such that the lever part is restricted from rotating in a direction opposite to a rotation direction when the pedal part is operated.
