  • Patent number: 7409278
    Abstract: A road surface friction coefficient ? is calculated based on a detected lateral acceleration and a front-rear acceleration, and a roll angle is calculated using a roll rate. Further, a maximum engine torque value that can be applied to a drive wheel without causing slipping thereof is calculated based on the road surface friction coefficient ? and a gear ratio. A torque transmission rate that indicates a reduction rate for engine output is set so as to reduce in accordance with a roll angle, and a target engine torque value is calculated by correcting the maximum engine torque value using the torque transmission rate. Accordingly, adjustment is executed such that the engine output is made smaller as the roll angle increases. Thus, abrupt changes in vehicle behavior are not caused by sudden starting of control, and it is possible to inhibit drive feeling from deteriorating.

    Abstract: A tamper monitor circuit detects voltage, temperature, and/or clock variations that may be associated with a circuit tampering technique, and triggers an appropriate tamper response. The tamper monitor circuit includes a reference oscillator, a detection oscillator, and a comparison circuit. The reference oscillator supplies a reference signal having a reference frequency. The detection oscillator operates at a circuit temperature and is energized with a supply voltage, and supplies a detection signal having a frequency that varies with variations in the circuit temperature, variations in the supply voltage, or both. The comparison circuit receives the reference signal and the detection signal and, in response to the reference signal, selectively determines the frequency of the detection signal, determines a frequency difference between two or more of the determined frequencies, and supplies a tamper detect signal if the determined frequency difference exceeds a predetermined difference threshold.

  • Patent number: 7210551
    Abstract: The invention is directed to a method for operating a level control system of a motor vehicle which includes: a control apparatus, sensors for the direct or indirect determination of the distance of the vehicle chassis to the axles of the vehicle wheels; and, actuators for adjusting the distance of the vehicle chassis to these wheel axles. In the method, the control apparatus checks in a desired-actual comparison based on determined measured values whether the inclination of the vehicle chassis exceeds predetermined limit values. When these limit values are exceeded, one or several of the actuators are actuated in order to obtain a level compensation in the sense of a horizontal alignment of the vehicle chassis. To avoid a turnover of the vehicle (1) in an operating situation on a slope (2), the level compensating control activity is prevented by the control apparatus when the vehicle (1) is disposed in a slope and slant position (angles ?, ?) which is impermissible for vehicle safety.

  • Patent number: 7132936
    Abstract: A sensor for measuring yaw rate or roll rate of an automotive vehicle comprises a freely rotating inertial disk and an angular rate sensor responsive to the rotation of the inertial disk relative to a housing. In one embodiment the inertial disk presents an alternating magnetic field at its circumference. The rate and direction of rotation of the inertial disk relative to its housing is determined by three magnetic field sensors such as linear Hall Effect sensors responsive to the field presented by the inertial disk. In another embodiment electronic cameras measure movement of fiducial marks on the inertial disk. Air surrounds the inertial disk and air viscosity gradually brings rotation to a stop. For yaw rate measurement the disk axis is oriented vertically and the inertial disk is supported in the radial direction by low friction bearings such as ball bearings or magnetic bearings and in the axial direction by substantially frictionless bearings such as magnetic bearings.

When curved portion enters a proximity actuation state relative first wall corresponding to a low tension state where tension is below a tension threshold level, a proximity sensor actuates a signaling device which alerts a user.

  • Patent number: 7109856
    Abstract: A control system (18) for an automotive vehicle (10) has a first roll condition detector (64A), a second roll condition detector (64B), a third roll condition detector (64C), and a controller (26) that uses the roll condition generated by the roll condition detectors (64A–C) to determine a wheel lift condition. Other roll condition detectors may also be used in the wheel lift determination. The wheel lift conditions may be active or passive or both.

  • Patent number: 7095332
    Abstract: An alarm device including a sensor having sufficiently high detection sensitivity. The sensor 51 in the alarm device 41 is disposed such that a plane M perpendicular to the detection direction P of the sensor 51 is aligned at a specified angle ? with respect to a plane V perpendicular to the sun visor 72 (the lower surface 61a), were the specified angle ? should be set to be an approximately mean value of the expected minimum angle ?=0° and the expected maximum angle ?=40° (in this case, ?=20°). In other words, the plane M perpendicular to the detection direction P of the sensor 51 should be aligned at an angle ?(?=90°??) of less than 90° with respect to the sun visor 72 (the lower surface 61a). The alarm device may be mounted onto a vehicle for preventing the vehicle theft.

  • Patent number: 7084755
    Abstract: The invention relates to a method for monitoring the area of technical rolling bodies, especially their supports, wherein the forces exerted in that area are detected with sensors in order to generate electrical energy and to detect changes in the state of the area. At least one of the sensors (2, 3, 4) arranged in the area of the technical rolling bodies is actively impinged upon with electrical energy and introduces impulses that can be evaluated in the support (1) of the sensor (2, 3, 4) working as actuator. Thus, impulses that can be evaluated can be detected at any given time by the sensors (2, 3, 4) in the area (1) of the technical rolling bodies during monitoring with an electrical evaluation unit.

  • Patent number: 7057503
    Abstract: A roll angular velocity sensor and a lateral velocity sensor are operatively coupled to a processor, which generates a signal for controlling a safety restraint system responsive to measures of roll angular velocity and lateral velocity. In one embodiment, the processor delays or inhibits the deployment of the safety restraint system responsive to a measure responsive to the measure of lateral velocity, either alone or in combination with a measure of longitudinal velocity. In another embodiment, a deployment threshold is responsive to the measure of lateral velocity. The lateral velocity may be measured by a lateral velocity sensor, or estimated responsive to measures of lateral acceleration, vehicle turn radius, and either longitudinal velocity or yaw angular velocity, wherein the turn radius is estimated from either a measure of steering angle, a measure of front tire angle, or measures of forward velocity from separate front wheel speed sensors.

  • Patent number: 7040722
    Abstract: The invention relates to a method for redundantly estimating, i.e. by various sub-methods, the risk of lateral overturn of a vehicle. One sub-method involves estimating the risk of overturn according to the actual braking state of the vehicle—braking or strong braking, or not braking or slight braking—by monitoring the rotational speed behavior of the wheels on the inside of the turn. Another sub-method involves pre-calculating the rolling motion of the vehicle about the longitudinal axis thereof over a short time span of, for example, 0.5 s to 1.5 s on the basis of instantaneous movement parameters and assessing the risk of overturn on the basis of the anticipated rolling motion.

    Abstract: An apparatus and method for estimating a turning characteristic of a vehicle provided with a controller that performs the following steps are provided. That is, the controller estimates a value corresponding to a standard turning state based on vehicle running data of when the vehicle is turning, estimates a transfer function between the value corresponding to the turning state and a value corresponding to an actual turning state, estimates a turning characteristic of the vehicle based on the transfer function, determines whether the vehicle is in a critical turning state, and the prohibits the estimated turning characteristic from being used when it is determined that the vehicle is in the critical turning state.
