A method adjusts a brake pedal feedback in a brake-by-wire vehicle brake system. The brake system includes a brake pedal and a simulation device associated with the brake pedal such that in a brake-by-wire mode of operation, the simulation device provides brake pedal feedback to the driver. An input signal is provided to a processor circuit of a control unit of the brake system. The input signal relates to a desired brake pedal feedback associated with a driver of the vehicle. The processor circuit generates a brake pedal feel output signal based on data regarding vehicle deceleration vs. travel of the brake pedal and on data regarding the vehicle deceleration vs. force on the brake pedal. Based on the brake pedal feel output signal, the control unit controls an output of the simulation device to establish the desired brake pedal feedback.

A regenerative braking control method of a vehicle, may include a first operation of determining a driving risk of a road surface on the basis of a status of the road surface while driving; a second operation of determining whether an accelerator pedal is released while driving; a third operation of determining whether a brake pedal is operated while driving; and a fourth operation of performing no regenerative braking when the accelerator pedal is determined as being released, the driving risk of the road surface is determined as being high, and when the brake pedal is determined as not being operated.

The invention being presented uses the motors already included in an electric vehicle to charge its batteries while in tow. The charging process provided by the invention is compatible with the charging speed of current battery technology. It will provide an effective way of charging vehicles in theater, when other sources of electrical energy may not be available. Moreover, the proposed system can actually extend the brake life of the towing vehicle and improve performance boundaries of the overall system.

A braking control apparatus for a vehicle including: a pedal stroke sensing unit configured to sense a pedal stroke of a brake pedal; a pedal simulator pressure sensing unit configured to sense pressure of a pedal simulator that provides a reaction force in response to a stepping force of the brake pedal; and a control unit configured to apply different computation methods by selectively utilizing a pedal stroke STR sensed by the pedal stroke sensing unit and pedal simulator pressure P_SIM sensed by the pedal simulator pressure sensing unit at a plurality of stages defined while the brake pedal is pressed and released, and decide required braking pressure P which is required for braking the vehicle.

A vehicle braking device performs a following control which makes an actual value of a physical quantity follow a first target value when the actual value of the physical quantity is a value outside a dead zone and a suppression control which suppresses a change of the actual value when the actual value is a value within the dead zone in order to control the physical quantity associated with the braking force to be the first target value. The vehicle braking device comprises a setting portion which sets a second target value which follows the first target value and which is smaller than the first target value, when the first target value is increasing and a control portion which performs a control to make the actual value approximate the second target value.

A control method of an idle stop and go system is provided. The method includes determining whether a stop condition of an engine operating in an idle state is satisfied and determining whether a pressure increase value of a brake oil formed during a predetermined time period is greater than a predetermined value when the stop condition of the engine is satisfied. A valve connected to a hydraulic line to which the brake oil pressure is transmitted is then temporarily closed and then reopened when the pressure increase value is greater than the predetermined value. The engine is stopped after the valve is temporarily closed and reopened.

The present disclosure provides a system and a method for controlling kick-back in an electric booster type brake system capable of reducing a kick-back phenomenon in which a hitting force is transmitted to a brake pedal due to a difference between a high braking hydraulic pressure already generated in a power piston of a second master cylinder by driving a motor and a low braking hydraulic pressure generated in a first master cylinder when a driver steps on a brake pedal, in a fall back situation in which electric power is not smoothly supplied to the motor due to a low voltage of a battery.

A vehicular collision avoidance control device includes: a collision avoidance control unit that receives a vehicle deceleration rate that is an actual deceleration rate of a traveling vehicle and obtains a first desired deceleration rate for avoiding collision with an obstacle based on the received vehicle deceleration rate, a relative distance to the obstacle, and a target relative distance; and a brake control unit that obtains a desired deceleration rate for controlling a brake device by performing first control based on the received vehicle deceleration rate and the first desired deceleration rate and performing second control based on the first desired deceleration rate and stops the first control upon detection of a brake operation performed by a driver.

A switch device may include a rod movable in association with an operation of a brake pedal, a main body case in which one end side of the rod is disposed, a movable board disposed in the main body case, and a connecting mechanism configured to connect the rod and the movable board. The movable board may be displaceable via the movement of the rod such that a movable contact point of the movable board is in contact with or separate from a fixed contact point. The connecting mechanism may include a protruding portion radially protruding from the rod, and a wall portion provided in the movable board. After pushing the rod into the main body case by a predetermined length, a tooth portion disposed on the protruding portion may mesh with a tooth portion disposed on the wall portion connecting the rod and the movable board.

A method and associated apparatus for emergency stopping of a vehicle which has an electronic control unit (ECU) and speed sensors on each ground engaging wheel with other conventional components of a motor vehicle wherein once the apparatus for rapid stopping of a motor vehicle is activated, the brakes will stop the forward motion/rotation of each wheel and once the rotation of the tire is ceased the transmission is activated such that the tire will be driven in the reverse rotation until the vehicle is stopped, once the vehicle is stopped the transmission is placed into the original position or into park.
