An apparatus for braking a vehicle includes wheel brakes configured to generate a braking force on each of wheels, a first actuator for supplying a braking force to the wheel brakes by using a first motor and a first master cylinder, a second actuator for supplying a braking force to the wheel brakes by using a second motor and a second master cylinder, a first electronic control unit (ECU) for controlling the first actuator and determining normal or faulty operation of the first and second actuators, and a second electronic control unit (ECU) for controlling the second actuator and determining the normal or faulty operation of the first and second actuators. When the first ECU and the second ECU are determined to be normal, the first ECU controls to brake some of the wheel brakes, and the second ECU controls to brake a remainder of the wheel brakes.

A system for controlling driving of a vehicle, includes one or more processors configured to: identify objects, including another vehicle, around a host vehicle and collect object information about the objects; collect road states information of road states in a traveling direction of the host vehicle; check the object information around the host vehicle and the road states information to identify a safety zone to which the host vehicle is able to travel; and control the host vehicle to travel to the safety zone when the other vehicle is detected in the traveling direction of the host vehicle in a state in which the host vehicle has entered a curved road.

A system for controlling driving of a vehicle, includes one or more processors configured to collect information about another vehicle identified in a traveling direction of a host vehicle, check whether a road in the traveling direction of the host vehicle is a straight road or a curved road, and control, in response to the check, the host vehicle to travel in a direction in which the host vehicle avoids the other vehicle when the host vehicle enters a curved section of the road and the other vehicle is detected in the traveling direction of the host vehicle, and perform braking of the host vehicle such that a traveling speed of the host vehicle is reduced.

A vehicle steering control method, device and system, and a vehicle are provided. The vehicle steering control method includes: in a case where a current vehicle speed is less than a turning vehicle speed threshold, steering of a vehicle is controlled by an Electric Power Steering (EPS) to implement cornering of the vehicle; in a case where a cornering condition of the vehicle is not reached during the cornering of the vehicle, the vehicle is controlled by an Electrical Park Brake (EPB) to perform single-side parking to assist in the cornering of the vehicle; and after the single-side parking of the vehicle is implemented, closed-loop control is performed on an electric control booster, the EPB and the EPS, and the vehicle is controlled to turn under the cornering condition.

A vehicle control system provided with a control device that includes a control lateral acceleration calculation unit that calculates a control lateral acceleration from a lateral acceleration obtained by using a planar two degrees of freedom model of a vehicle based on vehicle state information and disregarding a second order delay component determined from vehicle specifications, a steer drag differential value calculation unit that calculates a steer drag differential value, an additional deceleration calculation unit that calculates an additional deceleration to be applied to the vehicle according to the steer drag differential value, and an additional braking force calculation unit that calculates an additional braking force to be generated by the braking force generator according to the additional deceleration.

A travel control method includes using the vehicle to autonomously control a travel of the vehicle. The vehicle has an autonomous speed control function for autonomously controlling a traveling speed of the vehicle and an autonomous steering control function for autonomously controlling the steering of the vehicle. The autonomous speed control function includes a curved route speed control function for controlling the traveling speed of the vehicle at a set speed corresponding to the size of a curve of a travel route. The curved route speed control function can be set to ON/OFF. Each of the autonomous speed control function and the autonomous steering control function can be set to ON/OFF. When the autonomous speed control function and the autonomous steering control function are set to ON, the curved route speed control function is operated regardless of whether the curved route speed control function is set to ON or OFF.

In this brake control device for a motorcycle, a deceleration threshold value calculation unit limits target wheel deceleration to a threshold value or less on the basis of a bank angle estimated by a bank angle calculation unit. Thus, the behavior of the vehicle body during turning of the motorcycle can be made more stable so as not to cause discomfort to a driver.

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.
