A CONTROL DEVICE AND A METHOD FOR CONTROLLING VEHICLE SPEED
A method and a control device for controlling speed of a vehicle having an automatic cruise control system configured to automatically control speed based on a set speed and to automatically reduce the speed to a predetermined safe speed below the set speed as it is detected that the vehicle approaches a road section of a predetermined type such as a curve. The method includes while automatically controlling the speed towards the predetermined safe speed as the vehicle approaches the road section of the predetermined type, receiving a request from a driver of the vehicle to control speed to a temporary speed different from the predetermined safe speed and the set speed. The method includes in response to said request, controlling the speed to the temporary speed. The method includes at an end of the road section of the predetermined type, automatically controlling the speed based on the set speed.
SYSTEMS AND METHODS FOR HANDLING CUT-IN TRAFFIC FOR AUTONOMOUS DRIVING
A method of operating a vehicle, comprises determining, by a computer located in a first vehicle, that an initial distance between the first vehicle and a second vehicle is less than a first distance or a second distance, where the second vehicle is located in a same lane as and in front of the first vehicle; generating, in response to the determining, a sequence of position values and velocity values for the first vehicle, wherein each of the position values and each of the velocity values are associated with a time value; and causing the first vehicle to increase a distance between the first vehicle and the second vehicle by causing the first vehicle to move or operate according to the sequence of position values and velocity values.
Systems and methods for optimizing travel time using route information
A power management system includes a sensor interface that receives sensor data samples during operation of a vehicle. A storage device stores the sensor data samples for multiple points in time along a route segment traveled by the vehicle. One or more processors analyze the sensor data samples to detect a historical pattern of the vehicle. The one or more processors determine time efficient operational parameters for the vehicle in response to a destination and an estimated travel time to the destination. The estimated travel time may be based on predicted conditions of the vehicle indicated by the historical pattern. The time efficient operational parameters may be selected to decrease the estimated travel time. At least one of the sensor data samples may include telemetry data.
Method for determining a motor vehicle speed profile
A method for determining a speed profile of a motor vehicle on a route between a starting point and an arrival point. The method includes the steps of defining a series of noteworthy points of the route, which are characterized by a stoppage of the vehicle or a decrease in the speed of the vehicle, the series of noteworthy points dividing the route into a series of portions, for each portion of the route, generating a speed and/or torque setpoint optimizing the speed profile of the vehicle by minimizing the Hamiltonian of a system of equations modeling the driving of the vehicle, and providing the setpoint generated on each portion of the route so as to optimize the driving of the vehicle up to the arrival point.
Using discomfort for speed planning in responding to tailgating vehicles for autonomous vehicles
Aspects of the disclosure relate to controlling a first vehicle in an autonomous driving mode. While doing so, a second vehicle may be identified. This vehicle may be determined to be a tailgating vehicle. An initial allowable discomfort value representing expected discomfort of an occupant of the first vehicle and expected discomfort of an occupant of the second vehicle may be identified. Determining a speed profile for a future trajectory of the first vehicle that meets the value may be attempted based on a set of factors corresponding to a reaction of the tailgating vehicle. When a speed profile that meets the value cannot be determined, the value may be adjusted until a speed profile that meets the value is determined. The speed profile that meets an adjusted value is used to control the first vehicle in the autonomous driving mode.
Apparatus for controlling vehicle and method thereof
An apparatus for controlling a vehicle capable of performing autonomous driving is provided. The apparatus includes an autonomous driving device that executes the autonomous driving and generates a transition demand when it is impossible to execute the autonomous driving. A driving controller performs a minimum risk maneuver (MRM) of applying a deceleration pattern differently depending on a driving environment of the vehicle, when the transition demand is generated, but when driving manipulation by a driver does not occur. A subsequent safety ensuring function is performed according to the MRM for the driver to recognize the MRM, and a drive mode of the vehicle is changed to a drive mode with a rapid response speed to acceleration or steering.
