    Abstract: There is provided an autonomous driving device that improves the convenience for a driver in the switching between autonomous driving and manual driving. When the driver discovers an obstacle which cannot be detected by an autonomous driving device, and performs a driving operation which causes a manual driving switching threshold value to be exceeded for an operation time less than or equal to an operation threshold value so as to avoid the obstacle, a control unit of the autonomous driving device switches autonomous driving to manual driving, and then the control unit switches manual driving to autonomous driving even if the driver does not perform an autonomous driving switching operation. For this reason, it is possible to improve the convenience for the driver in the switching between autonomous driving and manual driving.

  • Patent number: 9364188
    Abstract: With an X-ray apparatus for round visit of this invention, when a brake operation is carried out, a CPU performs deceleration control (braking current control at c and short brake control at e) of a movable carriage instead of immediately driving electromagnetic brakes, and drives the electromagnetic brakes at time f. Therefore, a great shock does not occur to the apparatus, and there is no possibility of the operator colliding with the apparatus. Since the deceleration control of the movable carriage is carried out in advance, the apparatus does not stop suddenly and does not impair the floor. As a result, the X-ray apparatus for round visit is realized, in which no great shock occurs to the apparatus at times of deceleration, and which is also safe for the operator.

The display quantity is termed “Dynamic Fuel Cost” or DFC, usually measured and displayed in currency (such as Dollars or Euros) per hour. Once every second or so, up to six modes of vehicle operation are detected, including steady speed, acceleration, deceleration by coasting (reduced power or parasitic drag), regenerative braking (in vehicles so equipped such as hybrids), friction braking, and zero speed idling. Then DFC is computed and displayed to the operator.

  • Patent number: 8335633
    Abstract: A driving control system includes a controller which is configured to, in response to a command for starting an auto-cruise mode generated by the operation of an input device, control an engine speed or a vehicle speed so that a value detected by a speed detector falls within a cruising speed range, when the value detected by the speed detector is outside the cruising speed range; and to then cause the watercraft to cruise at a constant engine speed or at a constant vehicle speed.

  • Patent number: 8301355
    Abstract: A cruise control system comprises a passing detection module and a speed regulator module. The passing detection module selectively detects execution of a passing maneuver based on an accelerator pedal position (APP) measured by an APP sensor and actuation of a Set/Coast input to the cruise control system when a vehicle speed is greater than a target speed. The speed regulator module regulates the vehicle speed based on the target speed and updates the target speed to the vehicle speed when the passing maneuver is detected.

  • Patent number: 8292784
    Abstract: In a vehicle control device, a brake feedback control unit calculates a brake feedback torque Tfb-BK using a PID control model when a current state is a brake feedback use state. The brake feedback control unit stops the calculation of the brake feedback torque Tfb-BK when the current state is a brake feedback limitation state, and stores as an output value the brake feedback torque Tfb-BK that is output at a brake limitation start timing. At a brake limitation release timing, the brake feedback control unit restarts the feedback control using the stored brake feedback torque Tfb-BK as an initial value. The brake mechanism can thereby generate a predetermined brake torque of not more than 0 [N·m] immediately after the brake limitation release timing.

  • Patent number: 8290680
    Abstract: A system and method for safely slowing or controlling a vehicle's speed or engine speed by selectively replacing a genuine engine control signal with a spoofed engine control signal to slow or control the vehicle. The operator is allowed control of the vehicle (e.g. genuine engine control signal) if the speed is below a threshold speed and the operator is denied control of the vehicle (e.g. spoofed engine control signal) if the speed is above the threshold speed; similarly, a maximum idle engine speed and time to idle before shut-down is enforced by selectively replacing a genuine engine control signal with a spoofed engine control signal, responsive to a set threshold for each. The threshold is set over the air (OTA).

  • Patent number: 8275528
    Abstract: Methods and systems for managing acceleration of a motor vehicle having an automatic transmission by controlling transmission turbine acceleration are provided. A desired transmission turbine acceleration is determined based on vehicle speed, turbine speed, and other information obtained from the vehicle transmission. One or more torque limits are determined as a function of the turbine acceleration. The torque limits are applied to manage acceleration of the vehicle.

  • Patent number: 8214125
    Abstract: A vehicle speed setting of cruise control is changed based on an operation by a driver. At this time, it is determined whether the vehicle is traveling in a passing lane or a traveling lane (S202). If the vehicle is traveling in a passing lane, the speed at which the vehicle speed setting is changed is increased (S206). If a blinker on the passing lane side of the vehicle is on (S205), the speed at which the vehicle speed setting is changed is also increased (S206) even if the vehicle is traveling in the traveling lane.

  • Patent number: 8162088
    Abstract: A speed control device for motor vehicles, having a controller and a user interface. A plurality of operating modes is implemented in the controller, which differ in their control strategies and include at least one eco mode, whose control strategy is optimized for a fuel-saving manner of driving. The user interface has an input device for selecting the operating mode. Use of the device is made advantageously in a hybrid vehicle. The control strategy may then be adapted to various parameters of the hybrid vehicle (charge state, power of the electric motor, scope of the regenerative braking).

  • Patent number: 8165774
    Abstract: A vehicle control system includes a sensor that generates a vehicle speed signal. A cruise control system generates a cruise control signal to maintain a vehicle at a target speed. A control module compares the vehicle speed signal to the target speed signal. The control module calculates different cruise control gains to delay changes in throttle position of the cruise control system when the vehicle speed signal is greater than the target speed.

  • Patent number: 8135531
    Abstract: Due to time delays, vehicle speed may become difficult to control. A predictive speed controller is configured to receive a desired speed request for a vehicle and simulate vehicle responses according to the desired speed request. A compensation value is derived from the simulated vehicle responses that compensates for the time delays of the vehicle. The actual speed of the vehicle is then controlled according to the compensation value.
