Brake assistance system and brake method
A brake assistance system comprising a brake pedal, a booster motor, a simulation motor, a planetary row coupling node, and a brake master cylinder, where the brake master cylinder is configured to provide a braking force for the vehicle. The brake pedal, the booster motor, and the simulation motor are separately coupled to the planetary row coupling node. The planetary row coupling node is configured to convert a torque of the brake pedal, a torque output by the booster motor, and a torque output by the simulation motor into an acting force acting on a piston rod in the brake master cylinder.
BRAKING CONTROL DEVICE
A braking control device includes a stop holding controller and an uneven-ground traveling determination unit. After the vehicle makes a stop and a brake operation performed by a driver who drives the vehicle is canceled, the stop holding controller is configured to perform execution of a stop holding control that includes holding braking force of the vehicle and canceling the braking force in response to a predetermined start operation performed by the driver. The uneven-ground traveling determination unit is configured to determine whether the vehicle is traveling on an uneven ground. The stop holding controller is configured to disable the execution of the stop holding control in a case where the uneven-ground traveling determination unit determines that the vehicle is traveling on the uneven ground.
VEHICLE REAR WARNING SYSTEM AND CONTROL METHOD THEREOF
A vehicle rear warning system includes: a driving information detection portion that collects information measured from a radar and a camera sensor in a reverse mode of a vehicle; and a controller that separates a danger zone and a safe zone with reference to a fixed obstacle at a rear of the vehicle by performing fusion of the information measured from the radar and the camera in the reverse mode of the vehicle, and generates a collision event and controls warning and braking when a moving object approaching from the danger zone is detected, while limiting the warning and braking for a moving object existing in the safe zone.

METHOD FOR ADJUSTING THE APPLIED PRESSURE OF A VEHICLE BRAKE AND VEHICLE BRAKE IN QUESTION
A method is for adjusting an application pressure of a vehicle brake, in particular a commercial vehicle disc brake, of a motor vehicle while the motor vehicle is in motion. The method includes the following steps: applying an initial application pressure to the vehicle brake, determining a braking effect of the vehicle brake while the initial application pressure is applied to the vehicle brake, comparing the determined braking effect with a limit braking effect, reducing the initial application pressure to a reduced application pressure if the determined braking effect exceeds the limit braking effect.

Damping force control device
A damping force control device 10 comprises vary damping shock absorbers, a detector, and a controller. Each of the shock absorbers sets damping coefficient from a minimum value to a maximum value in order to adjust damping force. The detector detects vertical vibration state quantity relating to vibration of the sprung mass. The controller performs an ordinary control for setting the damping coefficient based on the vertical vibration state quantity and according to a predetermined control law suitable for an assumption that all of the wheels touch ground. The controller performs, when at least one of the wheels is an ungrounded wheel which does not touch the ground and each of the other wheels is a grounded wheel which touches the ground, a specific control for setting the damping coefficient of the shock absorber corresponding to the grounded wheel to a first specific value greater than the minimum value.
