    • The sensor successively calculates a rolling angle, pitch angle and azimuth from the coordinate transformation matrix with the level error and azimuth error compensated. It calculates azimuth error compensatory values using the GPS direction signal and calculates a difference between the GPS direction signal and magnetic azimuth signal under a condition wherein the reliability of the GPS direction signal is high, whereas it calculates azimuth error compensatory values using the calculated difference between the GPS direction signal and magnetic azimuth signal and the magnetic azimuth signal under a condition wherein the reliability of the GPS direction signal is not high and under a condition wherein the reliability of the magnetic azimuth signal is not low.
    • 传感器连续计算出坐标变换矩阵的平移角,俯仰角和方位角,并补偿了水平误差和方位角误差。 它使用GPS方向信号计算方位误差补偿值,并且在GPS方向信号的可靠性高的条件下计算GPS方向信号和磁方位信号之间的差异,而使用计算出的方差误差补偿值, 在GPS方向信号的可靠性不高且在磁方位信号的可靠性不低的条件下,GPS方向信号和磁方位信号以及磁方位信号。

    • A pneumatic tire having a tread layer. A rubber composition of the tread layer includes a specific diene-based rubber component, and either a specific zinc dithiophosphate vulcanization accelerator, or a specific zinc dithiophosphate vulcanization accelerator and a benzothiazole vulcanization accelerator. The zinc dithiophosphate vulcanization accelerator is contained in an amount of 0.2 to 5.0 parts by weight per 100 parts by weight of the rubber component. A molar amount of the benzothiazole vulcanization accelerator is one-half or more of a molar amount of the zinc dithiophosphate vulcanization accelerator. Further, the rubber composition contains a white filler in an amount of 15 parts by weight or more per 100 parts by weight of the rubber component. Produceability of the pneumatic tire is excellent, and a low heat build-up performance thereof is improved without any adverse effects on gripping performance.
    • 一种具有胎面层的充气轮胎。 胎面层的橡胶组合物包括特定的二烯系橡胶成分,特定的二硫代磷酸锌硫化促进剂,特定的二硫代磷酸锌锌硫化促进剂和苯并噻唑硫化促进剂。 二硫代磷酸锌硫化促进剂的含量相对于100重量份的橡胶成分为0.2〜5.0重量份。 苯并噻唑硫化促进剂的摩尔量为二硫代磷酸锌硫化促进剂的摩尔量的一半以上。 此外,橡胶组合物含有每100重量份橡胶组分为15重量份以上的白色填料。 充气轮胎的生产性优异,并且其发热性能低,而对夹持性能没有任何不利影响。
