[Problem] The present invention provides a vehicle brake system capable of shortening a delay time from time at which an execution request of a pre-crash brake executed by actuation of an electric booster is sent to time at which the pre-crash brake is actually actuated.

[Means for Resolution] In a vehicle brake system (1) including: a hydraulic unit (20); a braking control section (90) for controlling the hydraulic unit (20); a master cylinder (14); an electric booster (10); a booster control section (100) for controlling the electric booster (10); and a pre-crash brake execution determination section (110), the pre-crash brake execution determination section (110) sends information on a specified target value (P_tgt) for decelerating a vehicle to the booster control section (100) and the braking control section (90). When a change amount (ΔP) of the target value (P_tgt) received from the pre-crash brake execution determination section (110) exceeds a specified threshold value (ΔP_thr), the booster control section (100) drives the electric booster (10) prior to a command from the braking control section (90) and executes preceding brake control for generating a specified brake hydraulic pressure to a wheel cylinder.

A method of implementing autonomous emergency braking (AEB) for advanced driver-assistance systems (ADAS), the method includes receiving one or more first inputs and identifying one or more targets external to a host vehicle based on the one or more first inputs. The method further includes receiving one or more second inputs related to a turning status of the host vehicle and detecting a U-turn state associated with the host vehicle based on the one or more second inputs. The AEB algorithm may be modified in response to the detected U-turn state, wherein the AEB algorithm initiates an AEB event as necessary to avoid collisions with the one or more identified targets.

Provided is a collision avoidance control apparatus including a first sensor; a second sensor; a controller configured to execute collision avoidance control; and a memory configured to, when a specific object has been detected, record information on the detected specific object, the specific object being an object which has been detected by both of the first sensor and the second sensor, in which the controller is configured to execute the collision avoidance control when determining that there is an object based on any one of the first sensor and the second sensor, and determining that the object has been already recorded as the specific object in the memory.

A system for displaying contextually-sensitive braking information on a surface of a vehicle is presented. The system may include a transceiver, one or more memories, an electronic display disposed on the surface, and one or more processors. The one or more processors may be configured to detect a braking event of the vehicle, wherein the braking event has an associated braking force. The one or more processors may compare the braking force to a predetermined threshold braking force to determine whether the braking force exceeds the threshold braking force. The one or more processors may further cause the electronic display to display a braking indication having an intensity that is proportional to the braking force, wherein the braking indication may include a braking rationale corresponding to the braking event in response to determining that the braking force exceeds the threshold braking force.

An example system includes a roadside apparatus and an in-vehicle device for position-based parking of a vehicle, for example, in environments with weak GPS signals. The roadside apparatus determines a first posture data of a vehicle that includes a relative position and an orientation of the vehicle. The relative position is with respect to a predetermined location associated with the roadside apparatus. The roadside apparatus transmits the first posture data, and the in-vehicle device receives the first posture data. The in-vehicle device dynamically evaluates a predetermined rule with the first posture data. The predetermined rule defines a target posture data with respect to both relative position and orientation. The in-vehicle device controls, in response to the predetermined rule failing to be satisfied, the vehicle to perform a posture adjustment operation based on posture adjustment data determined from a difference between the target posture data and the first posture data.

A first obstacle colliding with the ADV is detected. A minimum deceleration that is required for the ADV to avoid colliding with a second obstacle within a predetermined proximity of a moving direction is determined. A brake command is generated based on the minimum deceleration. Then, the brake command is applied to the ADV, such that the ADV avoids collision with the second obstacle and softens an impact of the collision with the first obstacle.

The techniques and systems herein enable estimated-acceleration determination for AEB Specifically, for a potential collision, a determination is made as to whether the target of the potential collision is likely to be stopped prior to the potential collision (e.g., due to its own braking). One of a plurality of estimated-acceleration functions is then selected based on whether the target is likely to be stopped prior to the potential collision. Using the selected estimated-acceleration function, an estimated acceleration to avoid the potential collision is calculated. By selecting different estimated-acceleration functions based on whether targets are likely to be stopped prior to potential collisions, more-accurate estimated accelerations may be generated, thus enabling better collision avoidance and/or avoiding unnecessarily strong braking.

In a driving assistance apparatus, an object detecting unit detects an object that is present in a periphery of an own vehicle based on an image captured by an imaging apparatus provided in the own vehicle. An avoidance control unit performs collision avoidance control for avoiding a collision between the detected object and the own vehicle when a collision between the object and the own vehicle is likely. A light distribution control unit switches irradiated light of an irradiation apparatus provided in the own vehicle between high beam and low beam based on a predetermined switching condition. The light distribution control unit performs switching suppression control to suppress switching of the irradiated light from high beam to low beam while the avoidance control unit is performing collision avoidance control in a case where the irradiated light is set to high beam.
