A drive assist apparatus includes a detector and a traveling controller. The detector detects an operation target of automatic emergency braking of a vehicle. The traveling controller includes a calculator and a determiner, and controls the automatic emergency braking on the basis of a result of the detection performed by the detector. The calculator calculates each of a target deceleration rate and a variation rate. The target deceleration rate is a target value of a deceleration rate of the automatic emergency braking. The variation rate is a rate of variation in the deceleration rate required for the deceleration rate of the automatic emergency braking to reach the target deceleration rate. The determiner determines a contact risk of the vehicle with the operation target on the basis of the target deceleration rate. The calculator increases the variation rate when the contact risk is determined by the determiner as being relatively high.

When a collision occurs, a driving force of a drive shaft is transmitted to a reversing high-load multiple disk clutch via an inertia absorbing gear mechanism. Then, the driving force is transmitted to a gear via a gear, and inertia is absorbed and the driving force acts to rotate an output shaft at a low speed. On the other hand, when the gear rotates, a regenerative/backing up motor also rotates, and so-called regenerative driving is also performed. Due to these operations, the output shaft rapidly decreases in rotation speed, and goes into a rotation stopping state from a forward rotating state. Then, when a vehicle speed sensor detects that the vehicle speed has reached “0,” the regenerative/backing up motor is driven, the output shaft is driven to rotate reversely for several seconds, and thereafter, driving of the regenerative/backing up motor is stopped.

This disclosure relates to a method and system for an exterior display of a vehicle, such as an autonomous vehicle, configured to issue feedback prompts. An example method includes issuing a prompt via a human-machine interface on an exterior of a vehicle permitting an input indicative of an undesired condition of the vehicle.

A surroundings monitoring apparatus obtains the position of an object from a captured image of a region in a heading direction of a vehicle, and obtains a position obtainment accuracy. When the distance between the object and the vehicle becomes relatively short, the position obtainment accuracy increases. However, the distance between the object and the vehicle becomes shorter, the position obtainment accuracy may decrease. Therefore, if collision avoidance control is performed for an object selected on the basis of the position obtainment accuracy, there is a possibility that the collision avoidance control is not performed for an object which is most likely to collide with the vehicle. In view of this, the apparatus obtains, for each object, a required deceleration which is the magnitude of acceleration necessary for stoppage at a position before the object, and performs the collision avoidance control for an object which is the largest in the required deceleration.

The present disclosure provides an emergency braking system, an emergency braking method and a semitrailer, capable of improving the braking effect of the vehicle, thereby achieving improved safety for the vehicle. The system includes: a sensor component configured to collect sensed information on an environment where a semitrailer is located; and a braking controller configured to determine whether there is a risk of collision for the semitrailer based on the sensed information, and if so, calculate a maximum adhesive force that can be provided by a road surface the semitrailer is currently on, determine a first braking pressure corresponding to each wheel based on the maximum adhesive force and axle load information, and transmit to a braking system a first braking instruction carrying the first braking pressure for each wheel.

In one embodiment, a method for performing an obstacle detection for an ADV includes detecting an obstacle by a primary ADS and a secondary ADS using an obstacle detection algorithm based on sensor data provided by sensors on the ADV. In response to detecting the obstacle, a first controlled stop distance and a second controlled stop distance are calculated by the primary ADS and secondary ADS respectively based on a speed and a deceleration capability of the ADV. The first and second controlled stop distances between the primary ADS and secondary ADS are exchanged to determine a third controlled stop distance which is the maximum of the two. In response to determining that the ADV reaches within the third controlled distance between the ADV and the obstacle, a controlled stop operation is activated by the primary ADS to decelerate the ADV based on the third controlled stop distance.

A lane keeping assist apparatus of a vehicle with a trailer, a system having the same, and a method thereof include a processor to request an advancing vehicle to control partial braking over the trailer of the advancing vehicle based on a lane departure amount of the advancing vehicle when the advancing vehicle departs from a lane.

A system for detecting a vehicular collision (i) receives occupant data from at least one internal sensor; (ii) receives external data from at least one external sensor; (iii) determines positional information for at least one occupant of a vehicle; and (iv) generates a virtual reconstruction of the vehicle collision. The virtual reconstruction indicates a severity of vehicle damage and a severity of injury to the at least one occupant caused by the vehicle collision. The system may also utilized vehicle occupant positional data, and internal and external sensor data to detect potential imminent vehicle collisions, take corrective actions, automatically engage autonomous or semi-autonomous vehicle systems, and/or perform at least one action to reduce a severity of a potential injury.

Vehicle systems and methods for assisting a driver making a turn at an intersection are disclosed. In one embodiment, a vehicle includes a plurality of sensors configured to output a plurality of operational signals, one or more processors, and one or more non-transitory memory modules communicatively coupled to the one or more processors. The processors store machine-readable instructions that, when executed, cause the one or more processors to receive a signal indicating a driver of the vehicle is attempting to make a turn at an intersection. The processors are further caused to access a behavioral profile that is representative of the intersection. The processors are also caused to develop a perception as well as a risk associated with the intersection based on the plurality of operational signals from the plurality of sensors and the behavioral profile of the intersection. The processors are further caused to calculate at least one maneuver.
