    • The invention provides a radar system, which can increase a crossrange detection speed in the lane change state by employing a steering angle sensor, etc. loaded on a vehicle without providing additional hardware. A lane-change determining unit receives a yaw rate response from a steering angle sensor, etc., and determines whether the radar-loaded vehicle is in the steering operation for lane change. If the radar-loaded vehicle is in the lane change state, a gain setting unit shifts a tracker gain to a larger value than that in ordinary running, and calculates a range, a crossrange, a relative velocity, etc. relative to a target from the results of tracker processing executed by a filtering unit. By using the calculated range, crossrange, relative velocity, etc., a control determining unit determines whether there is a collision risk, and whether steering operation to avoid a collision is required. If there is a collision risk, a forward collision warning and a control signal for actuating automatic braking are issued. If automatic steering to avoid a collision is required, an automatic steering control signal is issued. When the lane change state is completed, the radar system is returned to the state employing a tracker gain for the ordinary running.
    • 本发明提供了一种雷达系统,其可以通过采用加载在车辆上的转向角传感器等而不增加额外的硬件来增加车道变化状态下的交叉检测速度。 车道变更确定单元从转向角传感器等接收横摆率响应,并且确定雷达负载车辆是否处于车道变换的转向操作中。 如果雷达负载车辆处于车道改变状态,则增益设定单元将跟踪器增益转移到比正常行驶中更大的值,并且计算相对于目标的范围,交叉范围,相对速度等 由过滤单元执行的跟踪器处理的结果。 通过使用所计算的范围,交叉范围,相对速度等,控制确定单元确定是否存在碰撞风险,以及是否需要避免碰撞的转向操作。 如果存在碰撞风险,则发出前向碰撞警告和用于启动自动制动的控制信号。 如果需要自动转向以避免碰撞,则发出自动转向控制信号。 当车道改变状态完成时,雷达系统返回到采用用于普通运行的跟踪器增益的状态。
