With Means Responsive To Speed Of Vehicle For Maintaining Speed At, Or Preventing It From Exceeding, A Particular Value Patents (Class 180/170)
  • Patent number: 11338804
    Abstract: 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.

    Abstract: A vehicle travel control system for a vehicle may include: a braking profile generator to generate a brake pressure profile or a target speed profile based on monitored driving information of a host vehicle and a target vehicle; and a controller to control a speed or a deceleration of the host vehicle based on the generated profile. In particular, the braking profile generator analyzes an intention of a driver of the host vehicle when the driver intervenes at least one of the speed or deceleration of the host vehicle being controlled, and the braking profile generator further revises the target speed profile or brake pressure profile when the analyzed intention represents preferences of the driver such that the controller controls the host vehicle based on the revised profile.

    Abstract: Disclosed is a bidirectional transmission control system for a vehicle. A road surface recognition apparatus collects an image of a road surface on which a vehicle drives currently, and forwards, after recognizing the type of the road surface on which the vehicle drives currently according to the image of the road surface, a corresponding first terrain mode request signal to an all-terrain controller through a signal transfer apparatus, so as to start a corresponding terrain mode in an all-terrain adaptive mode. In addition, the all-terrain controller forwards execution information about the terrain mode to the road surface recognition apparatus through the signal transfer apparatus, so as to implement state feedback of the terrain mode currently executed. The inconsistency of information transmission rates between an all-terrain control system of a vehicle and an input system can be coordinated, thereby aiding in real-time switching of various terrain modes.

  • Patent number: 11242053
    Abstract: 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. During the cruise control mode, the controller calculates a torque command value for the driving motor by using proportional control based on a deviation between the vehicle speed and the target speed. 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.

  • Patent number: 10851889
    Abstract: While automatic driving control is being performed, traveling in a driving state of a vehicle corresponding to an unconverged region (including an unperformed region and a performed region) is preferentially selected between the traveling in the driving state of the vehicle corresponding to the unconverged region, and traveling in the driving state of the vehicle corresponding to a converged region. As such, learning control that corrects an amount of operation associated with control of the vehicle is performed more easily throughout the entire learning regions regardless of a usage state of the vehicle by a driver. Therefore, it is possible to achieve an appropriate traveling state at an early stage by the learning control that corrects the amount of operation associated with control of the vehicle.

  • Patent number: 10576950
    Abstract: A device and a method for controlling vehicle speed in a vehicle equipped with brake cruise control when the vehicle is travelling downhill are provided. The method involves driving a vehicle downhill with the brake set speed set to a first brake set speed; detecting a current vehicle speed; automatically applying a brake torque using at least an auxiliary brake to maintain the first brake set speed; and detecting a manual application of a vehicle service brake, in order to decrease vehicle speed. If a control unit detects that the driver is applying the service brake, then the control unit is automatically arranged to set the brake set speed to a second brake set speed that is lower than the first brake set speed; and to apply a brake torque using at least the auxiliary brake if a detected current vehicle speed exceeds the second brake set speed.

  • Patent number: 10569765
    Abstract: A PCM (14) for controlling a behavior of a vehicle (1) having steerable front road wheels is configured to perform a control to reduce a driving force for the vehicle (1) according to a yaw rate-related quantity (e.g., steering speed) of the vehicle (1). Specifically, the PCM (14) is configured, after reducing the driving force in response to a change in the yaw rate-related quantity and according to the yaw rate-related quantity being changing, to increase the driving force so as to restore a value of the driving force before the reduction, and the PCM (14) is operable, when increasing the driving force so as to restore a value of the driving force before the reduction, to change a change rate during the increasing of the driving force, according to a magnitude of the yaw rate-related quantity thereduring.

  • Patent number: 10507831
    Abstract: 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.

  • Patent number: 10471938
    Abstract: 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.
