A vehicle and a braking method and a device therefor are provided. The method includes the following steps: obtaining a first state information of the vehicle, where the first state information includes a vehicle mass and a deceleration required by braking; calculating a braking torque required by the vehicle according to the first state information, and controlling the vehicle to output an electric braking torque according to the braking torque required by the vehicle; obtaining a current vehicle speed of the vehicle and an electric braking exit protection speed; and calculating an electric braking exit speed according to the braking torque required by the vehicle and the deceleration required by braking, and controlling the vehicle to unload the electric braking torque when the current vehicle speed is less than a larger one of the electric braking exit speed and the electric braking exit protection speed.

There is provided a driving assistance device that executes deceleration assistance of a host vehicle when a relative situation between a deceleration object in front of the host vehicle and the host vehicle satisfies a preset deceleration assistance precondition and a driver of the host vehicle does not operate an accelerator and a brake, the driving assistance device including a first deceleration assistance execution unit configured to execute a first deceleration assistance when the deceleration assistance precondition is satisfied in a state in which the driver of the host vehicle does not operate the accelerator and the brake, and a second deceleration assistance execution unit configured to execute a second deceleration assistance when the driver releases the accelerator or the brake in a state in which the deceleration assistance precondition is satisfied.

A system, apparatus, and method for retrofitting a vehicle are presented. The method relates to a vehicle with a factory-installed first apparatus which communicates with a factory-installed second apparatus through a vehicle data bus using a first message. The method includes electrically disconnecting the vehicle data bus between the first apparatus and the second apparatus and electrically connecting a retrofit apparatus to the vehicle data bus. The method further includes transmitting a second message from the retrofit apparatus to the first apparatus which is indistinguishable from the first message.

A braking control device for controlling braking of a host vehicle. For a state in which a host vehicle is stopped in an intersection by automatic emergency braking and an oncoming vehicle is approaching in an oncoming lane, the host vehicle prohibits secondary braking is prohibited in, flashes a hazard lamp,and prohibits an idling stop. For a state in which it is determined in that the vehicle is stopped and it is determined in that it is safe for the vehicle to start moving, the host vehicle releases stop maintenance braking.

An advance driver brake customizing method applied to a brake customizing system is provided to identically implement a braking feeling set according to a driver's vehicle regardless of a vehicle type by transplanting driver braking feeling information of a driver's vehicle into a braking feeling matching vehicle. A braking characteristic of a brake of a brake system, which is applied to the braking feeling matching vehicle, is directed to follow the braking characteristic of a brake of the brake system, which is applied to the braking feeling matching vehicle, through driver matching control in conjunction with a wireless network. In particular, even when the same driver changes a vehicle or a driver for the same vehicle is changed, the same braking feeling is maintained.

Systems and methods for controlling a vehicle. One example system includes a deceleration actuator coupled to a first wheel of the vehicle and an electronic processor communicatively coupled to the deceleration actuator. The electronic processor is configured to receive a vehicle park command. The electronic processor is configured to, responsive to receiving the vehicle park command, determine a maximum holding pressure threshold. The electronic processor is configured to determine a requested braking pressure for the deceleration actuator. The electronic processor is configured to determine whether the requested braking pressure exceeds the maximum holding pressure threshold. The electronic processor is configured to, responsive to determining that the requested braking pressure does not exceed the maximum holding pressure threshold, control the deceleration actuator to apply, to the first wheel during a hold time, a holding braking pressure equivalent to the requested braking pressure.

A method for operating a brake system of an at least double-tracked motor vehicle comprises two breakable wheels, which are arranged at opposite ends of an axle, and a rollover protection system which can cause braking of the wheels in order to prevent a rollover situation. Automatic braking of that wheel of the axle which is loaded more greatly when cornering is brought about by way of the rollover protection system. Subsequently, a smaller steering lock angle or a lower lateral acceleration than in the case of the cornering which took place immediately previously, or a straightahead driving phase which immediately follows the cornering is detected. Thereupon, automatic braking of the two wheels on the axle is brought about.
