Abstract: In one embodiment, a system determines a signal fault at a communication bus of an autonomous driving vehicle (ADV). In response to determining the signal fault, the system sends a brake pre-charge command to a brake system of the ADV to pre-charge a brake of the ADV. The system determines a preset tolerance time to validate the signal fault. In response to a time elapse of the preset tolerance time, the system validates the signal fault at the communication bus or determine a signal fault at another communication bus. In response to validating the signal fault at the communication bus or determining the signal fault at the another communication bus, the system sends a brake command to the brake system of the ADV to engage brakes for the ADV.

Abstract: A device and a method for controlling collision avoidance of a trailer vehicle in platooning include a jackknife induction determination module or operation that determines whether to execute jackknife induction control in a leading vehicle when an emergency braking situation occurs during platooning of the trailer vehicle. The device and method also include a jackknife induction control module or operation that provides an additional braking distance of a following vehicle at the rear of a tractor by inducing pivoting of a trailer while controlling the tractor and trailer of the leading vehicle, respectively, to allow a jackknife phenomenon to occur. Stability of the platooning is improved by reducing a possibility of the occurrence of a collision accident by the following vehicle even during emergency braking.

Abstract: The present disclosure discloses a digital hydraulic assisted braking system with a high dynamic response and a control method thereof. The system includes a two-position two-way digital switch valve A, a controller, an electromagnetic two-position two-way proportional reversing valve, a two-position two-way digital switch valve B, a displacement detection system, and a pressure detection system. When a vehicle starts, a control system of the present disclosure maintains a preload state and responds to a braking at any time. During an emergency braking, the braking system is open. When the vehicle is shut down, the braking system is closed. Compared with an existing braking method, by implementing the braking method of the present disclosure, a braking response time is greatly shortened, a dynamic performance of a braking response period is improved, and a safety of vehicle braking is further guaranteed.

Abstract: A method and apparatus are provided for optimizing one or more object detection parameters used by an autonomous vehicle to detect objects in images. The autonomous vehicle may capture the images using one or more sensors. The autonomous vehicle may then determine object labels and their corresponding object label parameters for the detected objects. The captured images and the object label parameters may be communicated to an object identification server. The object identification server may request that one or more reviewers identify objects in the captured images. The object identification server may then compare the identification of objects by reviewers with the identification of objects by the autonomous vehicle. Depending on the results of the comparison, the object identification server may recommend or perform the optimization of one or more of the object detection parameters.

Abstract: A road surface assessment apparatus for a vehicle includes an illumination device, a detector, and an assessment unit. The illumination device is configured to emit pattern light to a road surface on which the vehicle runs, or a surrounding of the vehicle. The detector is configured to detect the emitted pattern light. The assessment unit is configured to assess a condition of the road surface, on the basis of the detected pattern light. The illumination device intermittently emits the pattern light for a short time in such a manner that a period of time for which the pattern light is not emitted is longer than a period of time for which the pattern light is emitted.

Abstract: A brake integrated control section generates, as target values, a target braking force and a target wheel speed equivalent value of each electric brake device, and transmits the target braking force and the target wheel speed equivalent value to a target value transmitter. An electric brake control device of each electric brake device includes a braking force controller that controls an electric motor in accordance with the target braking force, a wheel speed controller that controls the electric motor in accordance with the target wheel speed equivalent value, and a control switcher. The control switcher switches between use of the braking force controller and use of the wheel speed controller in accordance with a predetermined condition.
