The invention relates to a method for decelerating a motor vehicle at least during emergency braking, in which method a first braking torque is applied to at least one front wheel of the motor vehicle by means of at least one service brake system of the motor vehicle. According to the invention, at least one parking brake different from the at least one service brake system is activated by a control apparatus of the motor vehicle and a second braking torque is thereby applied to the at least one front wheel while the first braking torque is applied. A further aspect of the invention relates to a motor vehicle.

An operational method for controlling a first brake pressure generator. The operational method includes reading the detected wheel speeds into the brake pressure generator control unit, simulating a control strategy of the secondary control unit for controlling the hydraulic unit based on the wheel speeds so that a brake pressure required at the respective wheel is ascertained, predicting the pressure resulting from the control strategy of the secondary control unit and the brake pressure at the first brake pressure generator, and controlling the first brake pressure generator in accordance with the predicted resulting pressure if the predicted resulting pressure exceeds a limit value, so that the pressure resulting at the brake pressure generator is lower than the predicted pressure due to an activation of the first brake pressure generator.

A braking assist control device for a vehicle including a detector and a braking assist control device is provided. The braking assist control device includes an acquisition unit configured to acquire information on an ambient environment of an own vehicle from the detector, and a control unit configured to cause the braking assist device to perform intersection entry prevention assist in a case where it is determined, using the acquired information on the ambient environment, that the own vehicle is approaching an intersection and an own lane in which the own vehicle is traveling is a non-priority lane with respect to an intersecting lane.

A method of emergency braking of a vehicle includes: displaying a brake button in a vehicle; determining pre-touch information on a distance before the brake button is touched by a user; determining post-touch information on a distance after the brake button is touched; and performing any one of a first brake control in which general braking is performed according to the degree of the pressing of the brake button and braking force is added from a first time point after the brake button is pressed, a second brake control in which the general braking is performed and braking force is added from a second time point that is after the first time point, and a third brake control in which the general braking is performed according to the pre-touch information and the post-touch information.

According to at least one aspect, the present disclosure provides a method of controlling an electro-hydraulic brake including an electronic brake-force distribution (EBD) control function, the method comprising: an emergency braking determination operation of determining whether emergency braking is required for a vehicle; a motor control operation of controlling a current flowing in a motor connected to a main master cylinder to increase hydraulic pressure supplied to wheel brakes when it is determined that the emergency braking is required; a rear wheel inlet valve closing operation of closing an inlet valve connected to a rear wheel brake for a predetermined time so that a pressure of the rear wheel brake is not increased earlier than a pressure of a front wheel brake; a closed time period calculation operation of calculating a time during which the inlet valve is maintained in a closed state; and a rear wheel inlet valve opening operation of determining whether a time during which the inlet valve is closed exceeds a closed time period (t), maintaining the inlet valve in the closed state until the time reaches the closed time period (t), and opening the inlet valve when the time exceeds the closed time period (t).

A driving assistance system that executes deceleration assistance of a vehicle when a relative state between the vehicle and a deceleration object ahead satisfies a preset condition includes a brake operation detection unit configured to detect whether a brake operation is performed by a driver of the vehicle during the deceleration assistance, a deceleration gradient setting unit configured to, when a brake operation is performed by the driver during the assistance, set a deceleration gradient to stop the assistance based on at least one of presence or absence of a forward obstacle ahead, a relative state between the vehicle and the forward obstacle, and a road environment in which the vehicle travels, and a deceleration assistance stop unit configured to, when a brake operation is performed by the driver during the assistance, stop the assistance of the vehicle along the deceleration gradient set by the deceleration gradient setting unit.

A driving support apparatus (10) executes collision prevention control for avoiding collision with the object when a possibility of a vehicle (VA) colliding with an object based on object information (e.g., distance, direction, and relative speed) acquired by a millimeter wave radar device (21) and a camera device (22) is high. Further, the driving support apparatus does not execute the collision prevention control when an accelerator pedal operation amount is equal to or larger than a stop threshold value. However, the driving support apparatus executes the collision prevention control even when the accelerator pedal operation amount is equal to or larger than the stop threshold value within a specific period of from a start point at which a predetermined erroneous operation condition is satisfied, to an end point, which is a time point after a predetermined consideration period has elapsed since the erroneous operation condition has no longer been satisfied.

A brake system includes a piston configured to generate hydraulic pressure of brake fluid stored in a brake system, and an electronic control unit (ECU) configured to calculate hydraulic pressure to be generated in response to an amount of movement of the piston. The ECU estimates a current temperature of the brake fluid, calculates a maximum estimated hydraulic pressure of the piston based on the estimated current temperature, and determines a maximum hydraulic-pressure reference value for backward movement control of the piston based on the maximum estimated hydraulic pressure.

A braking force controller causes a first actuator unit to generate a target jerk when the target jerk is equal to or larger than a first jerk, causes the first actuator unit to generate the first jerk and a second actuator unit to generate a jerk obtained by subtracting the first jerk from the target jerk as an additional jerk when the target jerk is smaller than the first jerk and equal to or larger than the sum of the first jerk and a second jerk, and causes the first actuator unit to generate the first jerk and the second actuator unit to generate the second jerk as the additional jerk when the target jerk is smaller than the sum of the first jerk and the second jerk.

A braking force control apparatus performs a brake assist control for assisting braking of a vehicle when there is an obstacle ahead of the vehicle and when a driver-deceleration, which is a deceleration corresponding to an operation of a brake pedal by a driver, is less than a necessary-deceleration, which is a deceleration needed to avoid the vehicle colliding with the obstacle. The braking force control apparatus includes: a calculator configured to calculate a deceleration profile in which a deceleration increases with time, as a part of the brake assist control, in order to stop the vehicle at a target position without the vehicle colliding with the obstacle; and an output device configured to output a target-deceleration based on the deceleration profile, as a requested-deceleration, as another part of the brake assist control.
