  • Patent number: 6942252
    Abstract: A selectively attachable road debris flap/splash guard for vehicles which is secured to a component of the vehicle hitch apparatus and which does not acquire access to the entire perimeter of the component of the vehicle hitch apparatus to which it is attached. In one exemplary embodiment, a hanger rail receiver is secured to a component of the hitch apparatus and accommodates a hanger rail positioned therein. The hanger rail extends from the hanger rail receiver, with a debris flap secured to and depending therefrom. Alternative mechanisms are disclosed for securing the hanger rail receiver to the hitch apparatus, none of which require access to the entire perimeter of the hitch component to which the hanger rail receiver is secured. In an alternative embodiment, the hanger rail is directly secured to a component of the hitch apparatus.

  • Patent number: 6938720
    Abstract: A steering input device for a steer-by-wire system is provided. The input device comprises a first shaft and a hand wheel. The first shaft is rotatably installed in a first housing. The hand wheel is connected to the first shaft such that the hand wheel and the first shaft drive one another. The hand wheel has a range of motion of between about ±45 degrees and about ±90 degrees. The hand wheel also has an outer dimension of about 12 inches. The range of motion and the outer dimension allow the steering input device to be installed in a vehicle in a non-conventional position relative to a twentieth century conventional position including at least one of the hand wheel extending from the first shaft extending along a length defining the vehicle on one of two sides thereof and the hand weel extending rearward in the vehicle farther than an instrument panel.

  • Patent number: 6935454
    Abstract: An improved valve for use in a hydrostatic drive apparatus for a vehicle such as a zero turn vehicle. For each hydraulic drive system in the vehicle, a valve is located between the high and low pressure sides of the closed hydraulic circuit connecting the hydraulic pump and motor. The valve opens when the pressure rise rate in the high pressure side reaches a set level to minimize pressure spikes in the high pressure side and thus improve performance of the vehicle. A valve block may be used to mount the valve, and a second valve may also be included therein to connect the two pressure sides of the hydraulic circuit in a similar manner when the vehicle is operated in reverse.

  • Patent number: 6935445
    Abstract: A back-up steering system is provided having a hydraulic pump, an accumulator, a mode control valve, a main solenoid valve, and a pair of back-up solenoid valves. The system is connected, to left and right service brakes. The hydraulic pump and the accumulator are both connected to a main hydraulic line. The main solenoid valve is connected to the main line, a common fluid sump, and the mode control valve. The back-up solenoid valves are each connected to the main line, the sump and the mode control valve. The service brakes are connected to the mode control valve. During normal operation the mode control valve is set so that the service brakes are in fluid communication with the mode control valve and the main solenoid valve. When the main solenoid valve is actuated the pump is in fluid communication with both service brakes for simultaneous actuation thereof, in response to operator induced braking.

  • Patent number: 6929082
    Abstract: In a parking assist apparatus that assists with moving, by automatic steering, a vehicle from an arbitrary stopping position to a target parking position set by the driver, a setting portion (i.e., a parking assist ECU) sets both a path from the stopping position to the target parking position and a steering operation necessary to bring the vehicle along that path. When this path cannot be set with the steering angle in the stopping position set as the initial steering angle, and when the path can be set with another steering angle as the initial steering angle, an instruction portion (i.e., a monitor or a speaker) instructs the driver to turn the steering wheel to this other steering angle.

  • Patent number: 6926112
    Abstract: The present invention provides a system for generating an end of travel feedback to the driver of a vehicle where the vehicle includes a steer by wire system. The system includes a steering wheel, a steering shaft, a motor, and a brake. The steering wheel is configured to control the steer by wire system. The steering shaft is coupled to the steering wheel and rotates in conjunction with the steering wheel. To provide road feel resistance to the driver, the motor is coupled to the steering shaft. Further, the brake is coupled to a shaft of the motor and is adapted to provide mechanical resistance when the road wheel is at an end of travel position.

  • Patent number: 6926105
    Abstract: An endless track assembly wherein the weight of an associated vehicle/equipment is supported by the track framework. The track assembly provides a framework having a number of idler rollers and a drive sprocket that mounts to a rotational drive power source. The weight of the vehicle is transferred from a vehicle/equipment support flange that cooperates with a complementary support surface of the track framework and an intermediate bearing liner. The bearing support surfaces cooperate to permit the track frame to pivot relative to the chassis independent of the drive sprocket. The track assembly is particularly adapted to pivoting irrigation systems.

  • Patent number: 6918609
    Abstract: A novel cover for a safety restraint device is disclosed. The cover is well-adapted for use in vehicles with modular airbag components. The novel cover configuration of the present invention effectively hides any evidence of the seam through which the airbag deploys, thereby improving the appearance and tamper-resistance of the airbag. The cover includes a seam with a nonlinear portion that impedes folding or bending of the outer layer in conformance with the seam. The nonlinear portion of the seam may include bends and linear segments in a variety of shapes and sizes, in homogeneous or heterogeneous arrangements, as dictated by the design parameters of the airbag and the manufacturing processes used to make the cover. The cover module of the present invention may be used with an outer layer of material designed to conceal the seam. With such a configuration, the nonlinear portion of the seam may keep the outer layer from form fitting to the seam so that no visible indentation over the seam will be shown.

  • Patent number: 6916031
    Abstract: A bicycle braking device includes a second drive assembly between the crankshaft and the rear axle of the bicycle. The second drive assembly includes a chain drive and pair of engaged gears for reversing the direction of rotation of the crankshaft with respect to the rear axle when the second drive is engaged. The device further includes a clutch for selectively engaging or disengaging the assembly. When the bicycle is moving forward and the second drive is engaged, the pedals will rotate in reverse of the direction of rotation required to propel the bicycle forward. A bicycle rider can apply force through his feet and legs against the rotating pedals to thereby slow and stop a moving bicycle.

  • Patent number: 6913109
    Abstract: A vehicle steering control system is provided which is capable of reliably protecting a motor for driving a wheel steering shaft. In the system, a current sensor and a motor rotational speed detection section respectively detect a current applied to the steering shaft drive motor and the motor rotational speed of the steering shaft drive motor, and current inference means infers the motor current applied to the steering shaft drive motor based on the detected motor rotational speed. Abnormal judgment means compares the current inference value obtained by the current inference means with a current detection value indicated by the current sensor to judge whether the current sensor is normal or not. Abnormal judgment output means outputs the result of the abnormal judgment when the current sensor is judged to be abnormal. When a trouble occurs that the current sensor fails to operate normally due to the malfunction or the like, such a trouble can be recognized at the early stage of the malfunction.
