    摘要： A control system (18) for an automotive vehicle (10) having a vehicle body includes a sensor system (16) having housing (52) oriented within the vehicle body. Positioned within the housing (52) are a roll angular rate sensor (31), a yaw angular rate sensor (30), a pitch angular rate sensor (32), a lateral acceleration sensor (27), a longitudinal acceleration sensor (28), and a vertical acceleration sensor (29). The vehicle (10) also has a safety system (38). The controller (26) determines a roll misalignment angle, a pitch misalignment angle and a yaw misalignment angle as a function of the sensor outputs of the roll rate, the pitch rate, the yaw rate, the lateral acceleration, the longitudinal acceleration and the vertical acceleration. The motion variables the vehicle along the vehicle body-fixed frames, including the roll rate, the pitch rate, the yaw rate, the lateral acceleration, the longitudinal acceleration and the vertical acceleration, are then compensated based on the detected sensor misalignments and the sensor outputs of the roll rate, the pitch rate, the yaw rate, the lateral acceleration, the longitudinal acceleration and the vertical acceleration. The controller (26) generates a control signal for controlling the safety system in response to the compensated roll rate, pitch rate, yaw rate, lateral acceleration, longitudinal acceleration and vertical acceleration.

    摘要： A road surface detection apparatus capable of detecting an upward/downward displacement in radar axis when detecting a road surface by projecting a radar beam. The apparatus projects a radar beam signal onto the road surface on which the radar-equipped vehicle is traveling, and receives a signal containing a reflected signal of the radar beam signal. Then, the apparatus compares the level of the road surface reflected signal contained in the received signal with a predetermined reference level and, if the result of the comparison lies outside a predefined range, then the apparatus determines that the axis defining the projection direction of the radar beam signal is displaced.

    摘要： When a motor vehicle is not in motion, an algorithm for establishing the initial zero point offset values for a yaw rate sensor as may be used in motor vehicle software control systems. The initial values are the manufactured values and are downloaded into the vehicle ECU at the time of the manufacture of the ECU. When the vehicle is waken at the vehicle assembly and the ignition is first turned on, the initial actual value of the zero point offset is stored both as a maximum and minimum value. At subsequent adjusting times when the vehicle is not moving, but the ignition is on, the spread between the maximum and minimum values are checked. If the spread becomes greater than a desired predetermined spread, the value, be it the maximum or minimum value reflects the measured value and the other value is adjusted to be within the desired spread. When the ignition is turned off and the vehicle is not moving, the zero point offset maximum and minimum values are stored in memory. The mean value is calculated to provide the new zero point offset value of the yaw rate sensor when the vehicle ignition is then turned on and the vehicle is not moving.

    摘要翻译： 当机动车辆不运动时，用于建立可用于机动车辆软件控制系统中的偏航率传感器的初始零点偏移值的算法。 初始值是制造值，在制造ECU时下载到车辆ECU中。 当车辆在车辆组件上被唤醒并且首先打开点火时，零点偏移的初始实际值被存储为最大值和最小值。 在车辆未移动但点火开启的随后的调整时刻，检查最大值和最小值之间的差值。 如果扩展变得大于期望的预定扩展，该值就是最大值或最小值反映测量值，另一个值被调整到期望的扩展之内。 当点火开关关闭并且车辆不动时，零点偏移最大值和最小值存储在存储器中。 计算出平均值，以便当车辆点火然后被接通并且车辆不移动时，提供横摆率传感器的新的零点偏移值。

    摘要： A vehicle system includes a vehicle including a sensor and processing circuitry including a memory onboard the vehicle. The processing circuitry is configured to receive a first data point, a second data point, and a third data point regarding the condition from the sensor at different times, record the first data point of the sensor data in the memory, determine, based on a comparison of the second data point and the first data point, that the second data point should not be recorded in the memory, record the third data point in the memory in response to a determination based on a comparison of the third data point and the first data point, and transmit the first data point and the third data point from the memory to the remote device.
