A method of controlling a brake system of a motor vehicle having a braking assistance function. The brake system including a master brake cylinder, activated with a brake pedal. A distance s between a valve piston connected to the brake pedal, and a transmission element, connected to a pressure piston of the master brake cylinder is sensed and the brake system is controlled as a function of the sensed distance s. Within the scope of this monitoring process, brake pedal release is detected even when the pressure-generating unit is activated. In addition, despite an active braking assistance function, consistent interplay occurs between activation by the driver and assistance-side activation of the brakes given satisfactory pedal feedback.

Systems and methods for coordinating and providing braking assistance between towing vehicles and towed vehicles during towing events, such as bidirectional charging towing events, are provided. The towing braking assistance may be provided by the towed vehicle in the form of an assistive braking torque output to assist the towing vehicle with meeting a target deceleration rate during the towing event. The assistive braking torque output may be provided to account for mutual vehicle deceleration events, brake compensation or brake fade events, and stability events of the coupled vehicles during the towing events, for example.

A system and method are provided for estimating and applying vehicle tire traction. Vehicle data (e.g., movement and location-based data) and tire sensor data are collected at a vehicle and transmitted to a remote computing system (e.g., cloud server). A wear status is determined, and traction characteristics determined for at least one tire, based at least on the vehicle data and the determined tire wear status. The predicted tire traction characteristics are transmitted from the remote computing system to an active safety unit associated with the vehicle, or a fleet management system, wherein the recipient is configured to modify vehicle operation settings based on at least the predicted tire traction characteristics. A maximum speed for the vehicle may be defined by the recipient, or a minimum following distance where, e.g., the vehicle is one of multiple vehicles in a defined platoon.

In the case where drive power of a vehicle is increased, a control device starts micro-braking control for generating a braking force on at least one wheel of a front wheel and a rear wheel. During execution of the micro-braking control, the control device estimates an efficacy factor that is a factor indicating a relationship of a magnitude of the braking force to a magnitude of a pressing force generated by a friction braking system. The control device estimates the efficacy factor for the wheel, to which the braking force is applied by the micro-braking control, on the basis of a deviation between generated drive power, which is based on a required value for a power source, and actual drive power actually acting on the vehicle, and the pressing force corresponding to the wheel, to which the braking force is applied by the micro-braking control.

A method includes ascertaining that an emergency braking operation of a single-track motor vehicle is to be automatically executed driver independently, and based on the ascertainment, automatically and driver-independently influencing a steering element of the motor vehicle during the execution of the emergency braking operation.

Herein is disclosed an image-based detection system comprising, one or more image sensors, configured to receive images of a vicinity of a control; and one or more processors, configured to identify within the images a control actuator and the control; detect a trigger action of the control actuator relative to the control based on the images; and switch from a normal control mode to a safety mode according to the detected trigger action.

This negative-pressure type booster device improves operation feeling for a driver at the time of a sudden braking operation. A valve body is provided with a flange part which extends in the radially outward direction from a front section of the valve body, and a plate is provided with a locking part which comes into contact with the flange part so as to restrict a movement in the axially forward direction relative to the valve body.

An emergency braking preparation system for a vehicle may include: a vehicle detector configured to detect a vehicle speed; a driving road detector configured to detect the type of a driving road; a surrounding environment detector configured to detect a surrounding environment of the vehicle; an emergency braking controller configured to control a braking pressure of a brake to a preset braking state; and a controller configured to control an FOV of a camera according to one or more of the vehicle speed detected by the vehicle detection unit, the driving road detected by the driving road detection unit, and the surrounding environment detected by the surrounding environment detection unit, and control the emergency braking controller according to the FOV of the camera.

In an emergency stop situation, the regenerative braking system is used to assist in rapid deceleration, by combining regenerative braking with conventional friction brakes. Sensors can also be used to trigger the braking systems, even before the driver is able to react. These sensors might include external cameras, ABS activation detection, radar and ultrasound.

In a braking maneuver using a braking assistant (9) in a motor vehicle (3), the braking assistant (9) initiates an automatic braking maneuver when an actual distance (a) between the motor vehicle (3) and an object (5) located ahead of the motor vehicle (3) becomes less than a specified minimum distance (a.sub.min). Then an acceleration of the decelerating vehicle (3) is ascertained during the braking maneuver, and if the acceleration is positive then the braking maneuver initiated by the braking assistant (9) is automatically interrupted.
