Patent number: 10507831Abstract: A cruise control system controls fuel supplied to an engine of a motor vehicle based in part on whether the vehicle is travelling on a positive gradient, a negative gradient, or a level surface. The system includes a sensor for detecting a position of an accelerator pedal of the vehicle, an inclinometer for detecting a gradient of a surface over which the vehicle is traveling; and an electronic processor operative to set a fuel flow rate. The fuel flow rate is set as a function of the accelerator pedal position detected at an activation time of the cruise control system, and that fuel flow rate is maintained at a constant rate if the vehicle is travelling on a positive gradient or a level surface. The vehicle therefore slows down on the positive gradient rather than maintaining a target speed as with a conventional cruise control system.Type: GrantFiled: December 20, 2017Date of Patent: December 17, 2019Assignee: Ford Global Technologies, LLCInventor: Volker Haupts

Patent number: 10000209Abstract: A vehicle steering control apparatus includes a target course setter, a first control quantity calculator, a second control quantity calculator, a control rate variator, and a steering controller. The target course setter sets, based on forward environment information, a target course to be traveled by an own vehicle. The first control quantity calculator calculates a first control quantity that allows the own vehicle to travel along the target course. The second control quantity calculator calculates a second control quantity based on a steering angle. The control rate variator variably sets, in accordance with a vehicle speed, a first rate of the first control quantity and a second rate of the second control quantity. The steering controller calculates a steering control quantity, based on the first control quantity corrected based on the first rate and the second control quantity corrected based on the second rate, and executes a steering control.Type: GrantFiled: May 17, 2016Date of Patent: June 19, 2018Assignee: SUBARU CORPORATIONInventors: Yasushi Takaso, Takashi Kubo

Patent number: 9981662Abstract: A vehicle includes a speed detector detecting a vehicle speed, a brake system and a control system implementing a control mode including determining a threshold speed. The control system further derives an initial brake torque demand proportional to an error between the threshold speed and a vehicle speed exceeding the threshold speed and outputs to the brake system a rate-limited brake torque demand by applying a rate-limit operator based on the error to the initial brake torque demand.Type: GrantFiled: October 15, 2015Date of Patent: May 29, 2018Assignee: Ford Global Technologies, LLCInventors: Erick Michael Lavoie, Joseph M. Raad, Donald Jacob Mattern

Patent number: 9969392Abstract: A vehicle speed control system for controlling a vehicle having a plurality of wheels. The vehicle speed control system is configured to automatically control the speed of the vehicle in dependence on an input target set-speed. The system carries out a method that includes: applying torque to at least one of the plurality of wheels; receiving a user input of a target set-speed at which the vehicle is intended to travel; and applying torque to the at least one of the plurality of wheels for propelling the vehicle at a vehicle control speed. The system further controls the vehicle control speed as a function of at least one of the instantaneous vehicle speed and the terrain over which the vehicle is travelling.Type: GrantFiled: October 21, 2014Date of Patent: May 15, 2018Assignee: Jaguar Land Rover LimitedInventors: Andrew Fairgrieve, James Kelly

Patent number: 9896099Abstract: A system and method for minimizing shift cycling for low speed engine operation with a vehicle cruise control. A vehicle control system operating in a cruise control mode determines a deficiency in vehicle speed between a measured vehicle speed and a cruise set speed. The deficiency is determined by comparing the vehicle speed to the cruise set speed, and includes using the compared valued to find a cruise speed margin, which is continuously updated. While the cruise control system is active, the control system logic determines the time at which a transmission upshift occurs based on the cruise speed margin. The vehicle speed, at which the upshift is made, is determined as a function of the updated cruise speed margin. An upshift is not made, if a likely drop in vehicle speed would result in the event a downshift would occur once the upshift is made.Type: GrantFiled: June 19, 2015Date of Patent: February 20, 2018Assignee: Allison Transmission, Inc.Inventor: Stephen West

Patent number: 9896093Abstract: A technique is provided in which detection of an impending collision results in the vehicle's control system taking steps to minimize damage to the passenger cabin, thereby increasing passenger safety. In particular, once an object is detected in the vehicle's pathway, the on-board controller determines whether or not a collision with the object (e.g., an on-coming car or a stationary object) is imminent. Once the system determines that a collision is imminent, the controller (i) deactivates the car's anti-lock braking system, (ii) locks-up the wheels, and (iii) rotates the front wheels to minimize intrusion of the wheels into the passenger cabin. The system may be configured to tailor the response to an imminent collision based on (i) vehicle speed, and (ii) probable impact area.Type: GrantFiled: September 15, 2015Date of Patent: February 20, 2018Assignee: ATIEVA, INC.Inventor: Axel Boris Vollmer
