A vehicle-control system for an automated vehicle includes a load-sensor and a controller. The load-sensor is used to determine a weight of a payload transported by a host-vehicle. The controller determines a response-characteristic used to operate the host-vehicle, wherein the response-characteristic is determined based on the weight of the payload. The load-sensor may be used to measure a ride-height of the host-vehicle, estimate the weight based on a test-acceleration of the host-vehicle, or estimate the weight based on a manifest that indicates a package-weight of a package transported by the host-vehicle.

Method and control unit in a vehicle for avoiding an accident at an unattended crosswalk. The method comprises: detecting an approaching crosswalk; detecting a Vulnerable Road User (VRU) in the vicinity of the crosswalk; determining that the detected VRU is going to walk across the road; determining a distance between the vehicle and the crosswalk; estimating a velocity of the VRU; determining a deceleration capacity of the vehicle, based on deceleration sensitivity of passengers on the vehicle, weight of the vehicle, and/or estimated friction between vehicle tires and the road; and determining a recommended action to be made by the vehicle.

A controller determines a load weight associated with a plurality of pneumatically independent circuits of a vehicle suspension system. The controller is adapted to receive an electronic pressure signal, at a controller electronic input port, based on a single pneumatic signal representative of respective pneumatic pressures in the plurality of pneumatically independent circuits. The controller is also adapted to determine the load weight based on the electronic pressure signal and control an operation of a function of an associated vehicle based on the load weight.

The present disclosure provides an advanced driver assistance system that includes a trailer detecting unit detecting whether a trailer is connected with a vehicle, and a trailer mass estimation unit estimating a mass of the trailer when the trailer detecting unit detects that the trailer is connected with the vehicle. The trailer mass estimation unit outputs a trailer mass signal. The advanced driver assistance system further includes a following distance determination unit determining a parameter of a following distance from another vehicle driving ahead of the vehicle to have the vehicle automated to follow the other vehicle at the following distance based on the parameter of the following distance. Moreover, the advanced driver assistance system includes a following distance adjustment unit adjusting the parameter of the following distance, which is determined by the following distance determination unit, based on the trailer mass signal.

Operating a vehicle with an open door creates risks. Embodiments herein consider both when a vehicle is in an autonomous driving (AD) mode and a manual mode. When in AD mode, if an occupant opens the doors while the vehicle is moving, the control system may lower the speed to stop and may park the vehicle (or not park it depending upon the control policy). If an occupant opens the doors when the vehicle is stationary, the control system may keep the vehicle from rolling and from brake system failures. When the vehicle is in a manual model and a door is opened when the vehicle is moving, a warning message may be triggered; whereas, if a door is opened when the vehicle is stationary, the control system may keep the vehicle from rolling and from brake system failures. Warning messages may be triggered for different stages/conditions.

In exemplary embodiments, methods and systems are provided that include: sensors configured to obtain sensor data for a vehicle having both friction braking and regenerative braking capabilities and coupled to a trailer, the sensor data including: friction braking data as to a vehicle friction braking force for the vehicle; and regenerative braking sensor data as to a vehicle regenerative braking force for the vehicle; and a processor coupled to the sensors and configured to at least facilitate controlling braking of the trailer by providing trailer braking force, via instructions provided by the processor, based on both the friction braking data and the regenerative braking sensor data, with a sensitivity toward the vehicle regenerative braking force such that the trailer braking force is affected differently by the vehicle regenerative braking force versus the vehicle friction braking force.

An in-vehicle device, an in-vehicle system, and a method for hands-free driving assistance are disclosed.
