  • 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.

    Abstract: In a constant speed drive (in an auto cruise), the procedure of the invention executes proportional control to set an accelerator opening Acc corresponding to an observed vehicle speed and a target vehicle speed. When the accelerator opening Acc is less than a preset opening A2 included in a dead zone where a torque demand Tr* is kept equal to 0, the procedure corrects the accelerator opening Acc to have a corresponding torque demand Tr* included in a negative zone where the torque demand Tr* takes negative values and linearly increases. This arrangement heightens the linearity of the graph of the torque demand Tr* against the accelerator opening Acc in the constant speed drive, compared with the linearity in a standard drive.

  • Patent number: 7200481
    Abstract: A vehicle driving assist system of the present invention detects a vehicle condition and a traveling environment of a subject vehicle; and calculates an extent of influence on the subject vehicle due to future changes in surrounding environment. The vehicle driving assist system then calculates the risk potential around the subject vehicle based on the extent of influence. Operation reaction force of an accelerator pedal is controlled according to the risk potential thus calculated.

  • Patent number: 7113860
    Abstract: A method for providing a cruise control warning system including monitoring a cruise control system to determine if the cruise control system is activated or deactivated for a vehicle. The method also includes receiving vehicle operation data for the vehicle. A likelihood that a slippery road condition exists for the vehicle is determined based on the vehicle operation data. A warning message is indicated to a driver of the vehicle when it has been determined that the likelihood that a slippery road condition exists is over a first pre-selected value and the cruise control system is activated.

  • Patent number: 7080705
    Abstract: An electronically controlled compression ignition engine is connected with an advanced cruise control system. The advanced cruise control system is capable of measuring distance to a vehicle or other object in front of equipment that is power by the compression ignition engine. Signals produced by the advanced cruise control system, at least in part, are used to determine the power output of the engine. In the event that the electronically controlled engine receives no signals from the advanced cruise control system, the electronic control may disengage or disable the advanced cruise control.

  • Patent number: 7023330
    Abstract: A vehicle capable of an extraordinary mode of motorized motion programmed to draw the attention of an operator. When one or more sensors sense a condition requiring attention of the operator, a periodic acceleration is superposed upon the motion of the ground-contacting members. The extraordinary mode of locomotion may include a mode where the vehicle alternates between braking and speeding up and braking over each period of the modulation.

  • Patent number: 6864784
    Abstract: A vehicle speed and safety system includes a stationary transmitting device positioned on a side of a road for generating and transmitting a signal indicative of a speed limit for a respective portion of the road and a unit positioned within a vehicle. The unit includes a receiver for receiving the signal indicative of a speed limit from the transmitting device. A microprocessor analyzes the received signal to determine a posted speed limit represented by said signal, monitoring a speed of the vehicle and compares the determined speed limit to the monitored speed. A display generates an alarm signal when the microprocessor determines the monitored speed exceeds the speed limit. The signal indicative of a speed limit is preferably transmitted at a frequency unique to the speed limit whereby each frequency represents a 5 mile per hour group of speed limits.

  • Patent number: 6857975
    Abstract: A rotation direction detection apparatus is configured to detect the direction of rotation of a pulley that is rotatably mounted to a chain guide, and includes a rotation sensor, a detection element and a shielding mechanism. The rotation sensor is fixed to the chain guide. The detection element is mounted to the pulley such that it can be detected by the rotation sensor. The shielding mechanism has a shielding arm that is mounted to move between a shielding position where the rotation sensor cannot detect the detection element and a detection position where the rotation sensor can detect the detection element. The shielding mechanism has a linking member that moves the shielding arm in tandem with the rotation of the pulley in first or second rotational directions. The shielding mechanism has a positioning protrusion that positions the shielding arm at either the shielding position or the detection position.

  • Patent number: 6831572
    Abstract: A rear collision warning system (10) for a target vehicle (17) and an approaching vehicle (18) is provided. The rear collision warning system (10) includes a first transmitter (54) located on the approaching vehicle (18) and directed at the target vehicle (17). The first transmitter (54) generates a vehicle information signal. A first indicator (16) located on the target vehicle (17). A first receiver (50) electrically coupled to the first indicator (16) receives the vehicle information signal and transmits a warning signal to the approaching vehicle (18) when the vehicle information signal is above a predetermined magnitude. A method of performing the same is also provided.

  • Patent number: 6820709
    Abstract: A cruise controller is provided, which regulates the driving speed of the vehicle not only beyond a certain minimum speed but also at speeds below a preselected critical speed down to standstill of the vehicle. Detecting the traffic situation using a distance sensor allows the vehicle to be automatically started once the driver has responded to a corresponding starting instruction. The starting instruction is effective until a preselected time limit, but, alternatively may also be repeated. However, in any traffic situation, the driver may override the cruise controller by operating the accelerator pedal or the brake pedal.

  • Patent number: 6792344
    Abstract: An apparatus and a method for controlling an automotive vehicle are disclosed, in which a control amount for securing safety of the vehicle and the control amount for achieving a state intended for by the driver of the vehicle are switched in such a manner as to reduce the shock due to the change in the torque generated from the power train, thereby accomplishing both safety and maneuverability at the same time. A first target value is set for controlling at least selected one of the driving torque, the driving force and the acceleration/deceleration rate. A second target value is calculated in accordance with the drive mode intended for by the driver or the driving environment ahead of the vehicle. In the case where a deviation exceeding a predetermined value develops between the first target value and the second target value, the fluctuations of at least one of the driving torque, the driving force and the acceleration/deceleration rate are suppressed.

  • Patent number: 6789637
    Abstract: The device ascertains a setpoint distance or a setpoint time gap with respect to a vehicle driving ahead as a function of the traveling speed, the distance control taking a minimum distance or a minimum time gap, specifiable by the driver, into consideration when determining the setpoint distance or the setpoint time gap. Since the driver's impression of distance is dependent on the visibility at the moment, in response to poor visibility (bad weather, darkness), the distance control increases the setpoint distance or the setpoint time gap ascertained for normal visibility.
