Abstract: A vehicle includes a sideslip preventing function of preventing a sideslip of the vehicle by separately adjusting a longitudinal force applied to each of the wheels. A controller controls the vehicle based on requests input from a driver assistance device, thereby causing the vehicle to travel autonomously. The controller calculates wheel lateral force request values based on the requests input from the driver assistance device. The wheel lateral force request values are request values of lateral forces acting on the respective wheels. The controller, when a behavior of the vehicle is in an oversteer state in a case in which the sideslip preventing function is failing, limits the wheel lateral force request values for the front wheels to values less than or equal to a first lateral force limit value, which is a limit value of the lateral force that can act on the rear wheels.

Abstract: An electric parking brake device includes: a “linear motion member configured to be driven by an electric motor, moved in a forward direction so as to apply a parking brake and moved in a backward direction opposite to the forward direction so as to release the parking brake”; and a “controller configured to control the electric motor”. When the parking brake is released, the controller stops energization to the electric motor at a time point when a first predetermined time elapses after a time point when an energization amount to the electric motor becomes constant.

Abstract: A braking control device includes a first control unit configured to execute first control for reducing a target braking force, which is either a front-wheel braking force to be applied to front wheels of a vehicle or a rear-wheel braking force to be applied to rear wheels during increasing of deceleration of the vehicle, in a case that a behavior of the vehicle is unstable as the target braking force is increased; and a second control unit configured to execute second control for reducing a rate of increase in the target braking force and increasing a rate of increase in the front-wheel braking force or the rear-wheel braking force, which is not the target braking force, prior to execution of the first control.

Abstract: Provided is a vehicle braking control device applicable to a vehicle equipped with an electric-powered parking braking device, a hydraulic braking device and a regenerative braking device. The braking control device comprises a first braking control unit and a second braking control unit. When a parking braking operation is performed while the vehicle is travelling, the first braking control unit implements a first braking process which increases the braking force to the vehicle by operating the hydraulic braking device. When the braking force to the vehicle needs to be increased in a situation where the first braking process is being implemented, the second braking control unit implements a second braking process which increases the braking force to the vehicle by operating the regenerative braking device.

Abstract: A resin molded article has an internal space. The resin molded article includes: a ventilation passage defined to allow the internal space to communicate with an outside of the resin molded article. The ventilation passage includes: a first ventilation passage extending from the internal space in a predetermined direction so as to include a bottom portion; and a second ventilation passage extending from the outside in a direction intersecting the predetermined direction. The first ventilation passage and the second ventilation passage communicate with each other by allowing the bottom portion to communicate with the bifurcated portions provided at an end portion of the second ventilation passage. A portion where the first ventilation passage and the second ventilation passage communicate with each other is narrowest in the ventilation passage.

Abstract: A control device is provided with a flow rate derivation part for deriving a pressure-holding-valve flow rate on the basis of a pressure command value and a previous pressure command value; a differential pressure derivation part for deriving a differential-pressure-valve differential pressure value so that the differential-pressure-valve differential pressure value increases with an increase in the difference obtained by subtracting the pressure-holding-valve flow rate from a pump-discharge flow rate; and a pressure-holding-valve processing part for performing an aperture derivation process to derive a command aperture so that the command aperture decreases with an increase in the difference obtained by subtracting the pressure command value from the sum of an pressure value and the differential-pressure-valve differential pressure value, and driving a holding pressure valve at the command aperture.

Abstract: This vehicle braking control device executes automatic braking control to adjust a braking torque on the basis of a vehicle target deceleration value corresponding to a distance between the vehicle and an object in front of the vehicle, and executes anti-skid control to suppress excessive wheel slip by adjusting the braking torque on the basis of a wheel speed. The braking control device calculates an actual deceleration value corresponding to the target deceleration value, and executes feedback control on the basis of the target deceleration value and the actual deceleration value such that the actual deceleration value approaches the target deceleration value. The configuration is such that a control gain of the feedback control is reduced when anti-skid control is executed. Further, the configuration may be such that execution of feedback control is prohibited when anti-skid control is executed.
