  • Patent number: 10647320
    Abstract: A device and a method for controlling vehicle speed in a vehicle equipped with cruise control while traveling downhill. The method involves driving a vehicle downhill with the cruise control set to a brake speed; detecting a current vehicle speed; applying the auxiliary brake to maintain the brake speed; detecting a request for a downshift from a current gear to a lower gear; and determining if a downshift is permissible at the current speed. If a downshift is not permissible, then a control unit automatically applies the service brakes to retard the vehicle speed; retarding the vehicle from a current speed to a lower speed at which a downshift to a lower gear is permissible; and performing a downshift to a lower gear when the second vehicle speed is reached. The cruise control is set to a second brake speed lower than the first brake speed.

  • 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: 10023188
    Abstract: A system, method, and apparatus includes management of cruise speed in anticipation of upcoming terrain changes. A cruise speed controller can be structured to predict a change in speed of vehicle in light of an upcoming terrain feature, and lead a change in reference speed to which the cruise speed controller is regulating vehicle speed to accommodate the upcoming terrain feature. In one embodiment a physics based model of the vehicle is used to predict a speed change. If predicted speed change exceeds a threshold, the cruise speed controller will initiate a change in speed to either speed up for an upcoming uphill terrain feature, or slow down for an upcoming downhill feature. In one form the distance in advance of the terrain feature as well as the velocity change profile (acceleration or deceleration) are determined by computation of a regression formula.

  • Patent number: 10000209
    Abstract: 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.

  • Patent number: 9981662
    Abstract: 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.

  • Patent number: 9896099
    Abstract: 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.

  • Patent number: 9896093
    Abstract: 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.
