Patent number: 11282387Abstract: A method and system generates a collision warning to a driver of a host vehicle. The system includes an on-board sensor of the host vehicle to detect presence of a preceding vehicle, wireless communication circuitry to establish wireless communication with a remote vehicle, and processing circuitry to detect existence of a slow remote vehicle ahead of the host vehicle, track an immediately preceding vehicle ahead of the host vehicle, confirm that the slow remote vehicle is affecting the host vehicle's lane speed of traffic by detecting that the immediately preceding vehicle is decelerating. When it is determined that, that the remote vehicle is sow, display an information message indicating the existence of the slow remote vehicle, and output, when the remote vehicle is slow and the preceding vehicle is decelerating, the collision warning as an audio sound and a visual message.Type: GrantFiled: February 26, 2020Date of Patent: March 22, 2022Assignee: TOYOTA MOTOR ENGINEERING & MANUFACTURING NORTH AMERICA, INC.Inventors: Vladimeros Vladimerou, Derek Stanley Caveney

Patent number: 10679501Abstract: Distributed control of vehicles with coordinating cars that implement a cooperative control method, and non-coordinating cars that are presumed to follow predictable dynamics. A cooperative control method can combine distributed receding horizon control, for optimization-based path planning and feedback, with higher level logic, to ensure that implemented plans are collision free. The cooperative method can be completely distributed with partially synchronous execution, and can afford dedicated time for communication and computation, features that are prerequisites for implementation on real freeways. The method can test for conflicts and can calculate optimized trajectories by adjusting parameters in terminal state constraints of an optimal control problem.Type: GrantFiled: May 3, 2017Date of Patent: June 9, 2020Assignee: TOYOTA MOTOR ENGINEERING & MANUFACTURING NORTH AMERICA, INC.Inventors: Derek Stanley Caveney, William Bruce Dunbar

Patent number: 8948995Abstract: A platoon model allows improved prediction of preceding vehicle future state. In this context, the preceding vehicle is a vehicle immediately ahead of the host vehicle, and the dynamic state of the preceding vehicle was predicted based on data received from one or more vehicles in the platoon. The intelligent driver model (IDM) was extended to model car-following dynamics within a platoon. A parameter estimation approach may be used to estimate the model parameters, for example to adapt to different driver types. An integrated approach including both state prediction and parameter estimation was highly effective.Type: GrantFiled: June 28, 2012Date of Patent: February 3, 2015Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Rohit Pandita, Derek Stanley Caveney

Patent number: 8620517Abstract: This disclosure relates to distributed control of a platoon of vehicles with nonlinear dynamics. Distributed receding horizon control algorithms are presented to derive sufficient conditions that guarantee asymptotic stability, leader-follower string stability, and predecessor-follower string stability, following a step speed change in the platoon. Vehicles compute their own control in parallel, and receive communicated position and velocity error trajectories from their immediate predecessor. Leader-follower string stability requires additional communication from the lead car at each update, in the form of a position error trajectory. Communication from the lead car is required only once at initialization. Provided an initially feasible solution can be found, subsequent feasibility of the algorithms are guaranteed at every update. The theory is generalized for nonlinear decoupled dynamics, and is thus applicable to fleets of planes, robots, or boats, in addition to cars.Type: GrantFiled: February 21, 2012Date of Patent: December 31, 2013Assignee: Toyota Mototr Engineering & Manufacturing North America, Inc.Inventors: Derek Stanley Caveney, William Bruce Dunbar

Patent number: 8315756Abstract: Method and system of vehicular path prediction for a vehicle travelling on a road. A yaw rate of the vehicle is estimated over a prediction time period based on vehicle sensor information and map information for the road. Then, a further path of the vehicle on the road is predicted for the prediction time period based on a speed and a direction of the vehicle, and the estimated yaw rate. Map information includes a geometry for a portion of the road on which the vehicle is travelling, and the vehicle sensor information includes yaw rate information from a yaw rate sensor on the vehicle, and location information of the vehicle relative to the map information from a positioning device on the vehicle.

Publication number: 20020197749Abstract: A process, and structure, used to monitor and control the level of photoresist removed at the periphery of a photoresist coated, semiconductor substrate, has been developed. A monitoring structure comprised of a group of graduated scribe marks, laser formed near the periphery of the semiconductor, monitoring substrate, is included with product semiconductor substrates, during the application of a photoresist layer, and during the photoresist edge bead removal procedure. The width of the photoresist edge bead, removed from product semiconductor substrates is determined via examination of the monitoring semiconductor substrate, in terms of measuring the level of graduated scribe marks, now exposed. This measurement determines the status of the product semiconductor substrates, in regards to continued processing, or rework.Type: ApplicationFiled: July 5, 2001Publication date: December 26, 2002Applicant: European Semiconductor Manufacturing LimitedInventors: Dennis Knight, Andrew Naylor, Rachel Watkins, Derek Stanley
