Patent number: 11338804Abstract: A vehicle control device comprises an operation amount sensor for measuring an operation amount of an accelerator element, an object sensor for detecting an object ahead of a vehicle, and a controller for applying a normal operation drive force which is determined depending on the operation amount to the vehicle. The controller executes an adaptive cruise control for applying a drive force required for an acceleration of the vehicle to become equal to an adaptive cruise control acceleration to the vehicle. The adaptive cruise control acceleration is an acceleration which increases as a difference between an inter-vehicle distance from the vehicle to an objective-forward-vehicle and a target inter-vehicle distance increases. When an erroneous operation start condition becomes satisfied, the controller ends the adaptive cruise control, and executes an erroneous operation related control for applying a drive force which is smaller than the normal operation drive force to the vehicle.Type: GrantFiled: March 23, 2020Date of Patent: May 24, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuto Shimbo, Yuma Hoshikawa

Patent number: 11242053Abstract: A vehicle control device includes an identifier identifying a vehicle speed of a vehicle having a driving motor, based on a rotation speed of a power transmission shaft, and a controller controlling operation of the driving motor. The controller can switch between a normal mode of controlling acceleration/deceleration in accordance with a driver's acceleration/deceleration operation, and a cruise control mode of maintaining the vehicle speed at a target speed without being dependent on the acceleration/deceleration operation.

If a prediction indicates that torsion in the shaft is to be released, the controller adjusts the torque command value such that an absolute value of torque of a proportional-control component is smaller than when the torsion is not to be released.Type: GrantFiled: October 1, 2020Date of Patent: February 8, 2022Assignee: SUBARU CORPORATIONInventor: Shoto Arai

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: 10471938Abstract: A method for the automated control of the longitudinal movement of a motor vehicle having an automated positive acceleration process in a longitudinal direction of the vehicle and an automated deceleration in the longitudinal direction of the vehicle. An acceleration variable is determined based on a jerk value and limited in terms of absolute value. And the jerk value is in turn determined in a driving mode in which, starting from a vehicle actual longitudinal speed and a vehicle actual longitudinal acceleration, the motor vehicle is adjusted to a predeterminable vehicle longitudinal speed taking into account a predeterminable maximum positive driving mode vehicle longitudinal acceleration, a predeterminable maximum driving mode vehicle longitudinal deceleration and at least one predeterminable driving operating mode jerk absolute value which limits the jerk.Type: GrantFiled: March 13, 2017Date of Patent: November 12, 2019Assignee: Ford Global Technologies, LLCInventors: Ashrit Das, Thomas Svensson

Patent number: 10364884Abstract: A gear shift mechanism controlled by a gear shift control device includes a plurality of engagement mechanisms and engages three engagement mechanisms to establish any one of a plurality of shift stages. The gear shift control device is adapted to change speed to a desired shift stage set by a manual operation. If a gear shift to the desired shift stage involves the skipping of one or more shift stages and the switching of two or more engagement mechanisms among the plurality of engagement mechanisms that are currently engaged, then the gear shift control device performs the gear shift to the desired shift stage such that the engagement mechanisms to be switched via a shift stage or stages to be skipped are switched one by one.Type: GrantFiled: March 2, 2017Date of Patent: July 30, 2019Assignee: HONDA MOTOR CO., LTD.Inventors: Kazuma Sasahara, Shintaro Kameda, Christopher Hopp
