    摘要： An automatic parking control is cancelled when a motor current has not yet reached a maximum current value Imax with a steering angle deviation exceeding a deviation threshold value. In addition, the automatic parking control is cancelled when a steering speed has not yet reached a maximum steering speed with a state where the motor current has reached and remains at the maximum steering speed continuing over a first time period. On the other hand, when a state where the steering speed has reached and remains at the maximum steering speed continues over a second time period, it is determined that there occurs an output shortage of a steering actuator, an automatic parking condition is recalculated, so as to allow the automatic parking continue to continue.

    摘要翻译： 当电动机电流尚未达到超过偏差阈值的转向角偏差的最大电流值I MAX时，自动停车控制被取消。 此外，当电动机电流达到的状态下转向速度尚未达到最大转向速度并且保持在第一时间段内持续的最大转向速度时，自动停车控制被取消。 另一方面，当转向速度达到并保持在最大转向速度的状态在第二时间段内持续时，确定转向致动器的输出不足，重新计算自动停车条件等 以允许自动停车继续。

    摘要： A brake application speed is compared with a speed threshold value so as to judge whether or not a braking operation being performed is an emergency braking operation. If not the emergency braking operation, an automatic parking mode is held. When the emergency braking operation is in effect, control information related to a state of an automatic parking control then is stored in a control information storage section, and the automatic parking control is cancelled. Thereafter, when a steering operation or a gearshift operation is performed before a cancellation of application of the brake is detected, the process is ended, and the control mode is held in an assist mode. When the application of the brake is cancelled with neither the steering operation nor the gearshift operation performed, the control information is read in so as to resume the automatic parking control.

    摘要翻译： 将制动施加速度与速度阈值进行比较，以判断正在执行的制动操作是否是紧急制动操作。 如果不是紧急制动操作，则保持自动停车模式。 当紧急制动操作有效时，与自动停车控制的状态相关的控制信息被存储在控制信息存储部中，并且自动停车控制被取消。 此后，当在检测到制动器的施加取消之前执行转向操作或换档操作时，处理结束，并且控制模式保持在辅助模式。 当既不进行转向操作也不切换变速操作而取消制动的应用时，读取控制信息，以恢复自动停车控制。

    摘要： In a steering-without-driving state, a larger current limit value, drive limit time and steering angle deviation threshold value are set than when a low-speed driving state occurs. An automatic parking mode is held until a time period over which a state where a motor current value of an electric motor which drives a steering mechanism is equal to the current limit value reaches the drive limit time. Even though the state where the motor current value is equal to the current limit value has continued over the drive limit time, the automatic parking mode is held during the steering angle deviation not exceeding the steering angle deviation threshold value. When the state where the motor current value is equal to the current limit value has continued over the drive limit time Ta and that the steering angle deviation exceeds the threshold value, the automatic parking control is cancelled.
