Abstract: A method for the longitudinal control of a vehicle according to a target trajectory specifying a series of target positions to be adopted by the vehicle over time. Based on an actual status of the vehicle, a control acceleration is determined for the purpose of trajectory control, by which the vehicle is to be accelerated according to specifications of the target trajectory. Based on an actual speed of the vehicle and a predefined maximum speed which should not be exceeded when travelling the target trajectory, a control acceleration for the purpose of speed control is determined, by which the vehicle is to be accelerated in order to travel at the maximum speed. Both control accelerations are supplied to an arbiter which determines a resulting control acceleration from same, wherein the vehicle is accelerated according to the resulting control acceleration. A device for the longitudinal control of the vehicle is provided.

Abstract: A method and device for longitudinal control of a vehicle as a function of a target trajectory, which specifies a series of target positions to be assumed by the vehicle over time. A controller actuating acceleration for trajectory control is determined based on an actual state of the vehicle. When the vehicle is following the target trajectory, a curvature of the target trajectory at a current position of the vehicle is determined from a local course of the target trajectory. Furthermore, when the vehicle is following the target trajectory, a longitudinal acceleration resulting from the target trajectory is determined as the current trajectory acceleration at the current position of the vehicle and the controller actuating acceleration is limited to a value that corresponds at most to a sum of the current trajectory acceleration and the acceleration offset. The vehicle is accelerated in accordance with the limited controller actuating acceleration.

Abstract: Vehicles, environmental control systems, and methods for operating an environmental control system are provided. In one example, the environmental control system (ECS) includes an ECS refrigeration unit that is configured to receive ambient air and a first portion and a second portion of hot bleed air. The ECS refrigeration unit is operable to indirectly exchange heat between the first portion of the hot bleed air and the ambient air to form a partially cooled, hot air stream, and to compress, further indirect heat exchange, and expand the partially cooled, hot air stream to form a cooled and expanded air stream. A low limit valve control regulates a low limit valve to control a rate of introduction of the second portion of the hot bleed air to the cooled and expanded air stream to form a combined air stream that when exiting the ECS refrigeration unit is a sub-freezing air stream.

Abstract: A method for determining whether a lane change is intended by the driver of a vehicle includes: reading in at least one object acquired in front of the vehicle; assigning one of a plurality of possible risk values to the object, the risk value representing a potential risk of the object to the vehicle; recognizing a lane change carried out, or that is to be carried out, by the vehicle during travel; and evaluating the recognized lane change to determine whether the lane change is intended or not intended by the driver, the evaluation taking place taking into account the risk value assigned to the at least one object.
