摘要： An electronic device that defends against an attack trying to identify confidential information from power consumption is provided without any circuit that performs a complementary operation to eliminate bias in power consumption. An elementary device A 100 is formed by a plurality of transistors 101-112. The elementary device A 100 receives inputs signals x1, x2, a random number r, and a control signal en, and outputs z. The output z is obtained by XORing (x1^r)&(x2^r) with the random number r. After the state transitions of the input signal, x1, x2, and the random number r, are settled, the control signal en is used to output z. This makes the signal transition rate of the output z equal, thereby defending against an attack trying to identify confidential information from power consumption.

摘要： A curve's radius of a road on which a vehicle shall run is estimated based on actual speed, yaw rate, and steering angle of the vehicle. Accordingly, during a transition state of the vehicle, the curve's radius can be estimated with the actual yaw rate taking into account the actual steering angle that can reflect more accurately turning behavior of the vehicle than the actual yaw rate. Therefore, errors in the estimation of the curve's radius due to response delay of the actual yaw rate can be easily reduced even though the yaw rate is used for such estimation.
摘要翻译：根据车辆的实际速度，偏航率和转向角来估计车辆行驶的道路的曲线半径。因此，在车辆的过渡状态期间，可以利用实际的横摆角速度来估计曲线的半径，该实际的偏航率考虑到可以反映车辆的更准确的转弯行为的实际转向角度比实际的横摆率。因此，即使横摆率用于这种估计，也可以容易地减少由于实际横摆率的响应延迟而导致的曲线半径估计误差。
