  • Patent number: 7392121
    Abstract: 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.

  • Publication number: 20070288145
    Abstract: 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.

  • Publication number: 20070288143
    Abstract: 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.

  • Publication number: 20070282499
    Abstract: In an automatic parking mode, a target path is obtained, and a vehicle is automatically controlled to follow the target path. When a driver intervenes steering of the vehicle, an anticipated course to be taken by the vehicle to follow after the intervention to the steering is calculated as a revised path. When the vehicle follows the revised path, if the vehicle is expected to be brought into contact with an obstacle, firstly, an alarm is raised. When an avoidance operation is performed after the alarm, an anticipated course to be taken by the vehicle to follow after the avoidance operation is re-calculated as a revised path. If no avoidance operation is performed or if the vehicle is expected to be brought into contact with the obstacle even when the vehicle follows the revised path, forced brakes are applied to the vehicle, and the automatic parking control is halted.

  • Publication number: 20070275917
    Abstract: An RNA capable of suppressing the expression of KLF5 gene, which comprises a sequence consisting of 15 to 30 contiguous nucleotides of KLF5 mRNA and a sequence complementary to the sequence, and which has been designed from the nucleotide sequence of Kruppel-like factor 5 (KLF5) cDNA. Specifically, a double-stranded RNA having a strand of a sequence shown in any one of SEQ ID NOS: 2 to 16 and a strand of a sequence complementary to the sequence, in which 2 uridylic acids are added to the 3?-terminus of each of the strands. By transfecting the RNA or a vector for expression of the RNA into cells, the expression of KLF5 gene in the cells can be suppressed. The RNA or a vector for expression of the RNA can be used as a therapeutic agent for cardiovascular disease or cancer.
