In a method for automatically adjusting the vehicle speed of a vehicle, while the distance to a preceding other vehicle is continuously measured, in order to reduce an initial distance, the vehicle is initially moved, in a drive phase, at a higher vehicle speed and is subsequently decelerated in a braking phase.

A navigation system includes a processor programmed to receive, from a sensor, an output related to a motion of the host vehicle. The output is generated at a first time that is later than a data acquisition time, when a measurement or data acquisition on which the output is based is acquired, and earlier than a second time at which the sensor output is received processor; generate, for a motion prediction time, a prediction of at least one aspect of host vehicle motion based, on the output and how the aspect of host vehicle motion changes over a time interval between the data acquisition time and the motion prediction time; determine a navigational action for the host vehicle; generate a navigational command for implementing at least a portion of the navigational action; and provide the navigational command to at least one actuation system of the host vehicle.

The present disclosure relates to a method for controlling a hydraulic brake system during a regenerative braking process. In the method, a hydraulic fluid is displaced in the direction of a wheel brake by means of a brake cylinder. In the method, furthermore, at least a volume fraction of the hydraulic fluid is conducted via a pressure dissipation valve into an accumulator, an isolation valve is adjusted in the direction of a closed state in order to at least partially hydraulically isolate the wheel brake from the brake cylinder, and at least a volume fraction of the hydraulic fluid is conveyed out of the wheel brake by means of a pump. The present disclosure furthermore comprises a hydraulic brake system for a motor vehicle, a computer program product, a control unit and a motor vehicle.

A system for navigating a host vehicle may: receive, from an image capture device, an image representative of an environment of the host vehicle; determine a navigational action for accomplishing a navigational goal of the host vehicle; analyze the image to identify a target vehicle in the environment of the host vehicle; determine a next-state distance between the host vehicle and the target vehicle that would result if the navigational action was taken; determine a maximum braking capability of the host vehicle, a maximum acceleration capability of the host vehicle, and a speed of the host vehicle; determine a stopping distance for the host vehicle; determine a speed of the target vehicle and assume a maximum braking capability of the target vehicle; and implement the navigational action if the stopping distance for the host vehicle is less than the next-state distance summed together with a target vehicle travel distance.

The present disclosure relates to a method for autonomously controlling a vehicle performed by a vehicle control system, the vehicle control system comprising a zone control system, a collision prediction system and a braking control system, the method comprising the steps of: defining in the zone control system at least a first zone and a second zone relative to a vehicle position, predicting a collision with an obstacle with the prediction system, autonomously braking the vehicle with the braking control system in a first braking mode if the collision is predicted to occur in the first zone and braking the vehicle with the braking control system in a second braking mode if the collision is predicted to occur in the second zone.

A brake device of the present invention includes: a wheel brake unit for braking a wheel; an electric motor for driving the wheel brake unit; a speed reducer for decelerating rotation of the electric motor; a rotation-linear motion converter for converting a rotational output of the speed reducer into a linear motion; and a braking force transmission member for transmitting the linear motion produced by the rotation-linear motion converter to the wheel brake unit.

This travel control device includes: a road determining unit which determines whether a road including a downward slope along which a vehicle is traveling includes a first curved road and a second curved road; and a travel control unit which, if the road determining unit has determined that the road contains the first curved road and the second curved road, causes the vehicle, when being caused to travel in such a way as to maintain a target speed, to decelerate at a curved road entry side of the first curved road and to coast from a curved road exit side of the first curved road, such that the vehicle can pass through the first curved road.

A driving control device of a vehicle includes a brake device and an ECU. The brake device is configured to apply a braking force to wheels. The ECU is configured to perform driving support control by calculating target deceleration of the vehicle and controlling the brake device such that deceleration of the vehicle reaches the target deceleration, to stop the driving support control when the driving support control is unable to be performed normally, and to determine whether or not a driver is in an abnormal state. The ECU is configured to decelerate the vehicle by controlling the deceleration of the vehicle so as to reach a predetermined value or more, when the driving support control is unable to be performed normally due to factors other than abnormality of the braking device in a situation where a determination that the driver is in an abnormal state is made.

A method for controlling longitudinal dynamics in a motor vehicle during an autonomous driving operation, where the presence of a front vehicle traveling ahead of the vehicle is ascertained with the aid of a surround sensor system; ascertaining at least one longitudinal dynamics variable of the front vehicle, which describes the longitudinal vehicle dynamics of the front vehicle, with the aid of the surround sensor system; and ascertaining at least one variable, which is used in a brake control system of the motor vehicle, as a function of the longitudinal dynamics variable of the front vehicle.

In a vehicle control system (1, 101, 201) configured for autonomous driving, a control unit executes a stop process by which the vehicle is parked in a prescribed stop area when it is detected that the control unit or a driver has become incapable of properly maintaining a traveling state of the vehicle, and a stop maintaining process for keeping the vehicle parked following the vehicle coming to a stop in the stop process. The control unit keeps the brake lamp turned on while the stop maintaining process is being executed.
