The present invention provides a method for the redundant measurement of the duty factor of pulse-with-modulated signals 12 via a vehicle control unit. According to the method, a direct determination of the duty factor of the signal 12 is performed by way of periodic sampling.

Apparatus for prognosing a vehicle brake-system health issue, and processes performed thereby. The apparatus in various embodiments includes a first sensor and a second sensor. In various embodiments, the first sensor is configured to measure a brake system input, such as brake pedal force or displacement, and the second sensor configured to produce output indicative of vehicle deceleration. The apparatus further includes a processing hardware unit, and a non-transitory computer-readable storage device. The storage device includes a prognostic module configured to cause the processing hardware unit to determine, based on the data received from the first sensor and the second sensor, whether there is an existing or potential brake-system health issue. In some implementations, the first sensor or the second sensor is configured to measure brake-line pressure.

A sensor device for a braking system equipped with an electromechanical brake booster, including evaluation electronics, which are configured to determine at least one braking request specification variable, while taking into account at least one actual variable with respect to a functionality of at least one component of the electromechanical brake booster and/or at least one setpoint variable for specifying the functionality of the at least one component of the electromechanical brake booster as a provided variable. A controller for a braking system equipped with an electromechanical brake booster, a braking system for a vehicle, a method for ascertaining a braking request specification variable to a braking system equipped with an electromechanical brake booster, and a method for operating a braking system equipped with an electromechanical brake booster, are also described.

A vehicle brake control apparatus according to the invention stops an activation of a brake device when a person exists outside of a braking area. The apparatus determines whether or not the person exists outside of the braking area on the basis of a moving direction and a moving amount of at least one characteristic point included in a landscape image captured by a camera device when a person image included in the landscape image cannot be detected by a pattern matching technique.

A method for operating a braking assistance system of a vehicle, wherein the braking assistance system assists a braking of the vehicle by a vehicle braking device in the event of a hazard braking. To differentiate between the hazard braking and a normal braking, at least two variables, representing a braking demand of a driver of the vehicle, are ascertained and a threshold value is established for each variable wherein hazard braking is recognized when at least the two variables exceed their particular threshold value, whereupon an automated braking intervention by the braking assistance system is initiated with the aid of the vehicle braking device. Furthermore, at least one driving-situation variable representing the instantaneous driving situation of the vehicle is ascertained and the at least two threshold values are changed depending on the at least one driving-situation variable.

A foldable brake pedal apparatus for an autonomous driving vehicle enables a pedal pad to protrude from a pedal housing in a popped-up state to make it possible for the driver to operate the pedal pad in a manual driving mode in which the driver manually drives the vehicle. In particular, the pedal pad is inserted into the pedal housing and blocked from being exposed to the driver in a hidden state so as to make it impossible for the driver to operate the pedal pad in an autonomous driving mode in which the driver does not manually drive the vehicle.

The present invention relates to a master cylinder arrangement (1) for a brake system (10), comprising a tandem master cylinder (2) including a master cylinder housing (20), a first master piston (23) movably arranged in the master cylinder housing (20), a second master piston (24) movably arranged in the master cylinder housing (20), a balancing piston (7) movably arranged in the second master piston (24), and an elastic pedal feel element (50). The invention further relates to a hydraulic system for a brake system as well as a brake system (10).

A vehicle body speed estimation device and a vehicle body speed estimation method are provided for estimating a vehicle body speed of a four-wheel drive vehicle from a wheel speed of each wheel of the four-wheel drive vehicle. In the vehicle body speed estimation device and a vehicle body speed estimation method, a controller determines whether a deviation of at least two of the wheel speeds among the wheel speeds is within a first prescribed range. The controller switches a method for selecting the wheel speed used for estimating the vehicle body speed between a first method and a second method when a sign of a drive torque that is applied to each of the wheels is reversed and the deviation of at least two of the wheel speeds among the wheel speeds is within the first prescribed range.

The present disclosure in at least one embodiment provides a braking system comprising: a pedal master unit; an electric booster unit; a reaction disc that generates a pedal force when compressed by at least one of the operating rod or the motor piston; and a controller that, upon receiving a regenerative braking interruption signal during the cooperative braking of the vehicle, senses a pressure change in the master cylinder and compensates for a displacement of the motor piston by an amount corresponding to the pressure change.
