    • A hydraulic parking brake device is selectively switched between a braking state and a non-braking state. A braking force decreases as a pressure in the control oil chamber increases and increases as the pressure in the control oil chamber decreases. The device includes a discharged oil restrictor located in a discharge passage and an accumulator connected to the control oil chamber. The accumulator is capable of releasing hydraulic oil to the control oil chamber when the braking force is greater than that at the time when the parking brake device is switched from the non-braking state to the braking state and the braking force can further be increased during the braking state of the parking brake device. Thus, the parking brake device can gradually brake the vehicle from the running state.
    • 选择性地在制动状态和非制动状态之间切换液压驻车制动装置。 随着控制油室中的压力增加,制动力随着控制油室中的压力的​​减小而减小。 该装置包括位于排放通道中的排放的限油器和连接到控制油室的蓄能器。 当制动力大于驻车制动装置从非制动状态切换到制动状态时,蓄能器能够将液压油释放到控制油室,并且制动力可以进一步增加 驻车制动装置的制动状态。 因此,驻车制动装置能够从行驶状态逐渐制动车辆。

    • A storage control system with auxiliary storages includes a system information generator which determines an optimum process data length and gap value to minimize switching between cylinders or tracks in reading/writing of data based on device information obtained from a specified auxiliary storage. Based on the determined optimum process data length and gap value, a data area generator secures a data area on the specified auxiliary storage. The system information generator determines the process data length and the gap value so that the process data length is less than the size of a track in the specified auxiliary storage and satisfies either of the following conditions: (a) Size of a track can be divided by the process data length; or (b) Sum of the process data length and the gap value is a value obtainable by multiplying the track size by an integer.
    • 具有辅助存储器的存储控制系统包括系统信息发生器,其基于从指定的辅助存储器获得的设备信息,确定最佳过程数据长度和间隙值,以使数据读/写中的气缸或轨道之间的切换最小化。 基于确定的最佳过程数据长度和间隙值,数据区发生器确保指定辅助存储器上的数据区域。 系统信息发生器确定过程数据长度和间隙值,使得过程数据长度小于指定辅助存储器中的轨道的大小,并且满足以下条件之一:(a)轨道的尺寸可以被划分 通过过程数据长度; 或者(b)过程数据长度和间隙值的和是通过将轨迹大小乘以整数而获得的值。

    • A control device executes a gear change control based on a first gear change map, in which the accelerator operation amount and the vehicle speed are used as parameters to define gear change timings, if a brake device is not actuated while the vehicle is running, and executes the gear change control based on a second gear change map, in which the brake actuation pressure and the vehicle speed are used as parameters to define gear change timings that positively utilize engine braking, if the brake device is actuated while the vehicle is running. The control device allows an automatic transmission to execute the gear change control in which engine braking is positively utilized according to conditions, contributing to diversified gear change control.
    • 如果制动装置在车辆行驶时未被致动,则控制装置基于第一变速图执行变速控制,其中,加速器操作量和车速用作定义换档定时的参数,以及 如果在车辆行驶时制动装置被致动,则基于第二变速图执行变速控制,其中制动器致动压力和车辆速度被用作确定正在利用发动机制动的变速定时的参数。 控制装置允许自动变速器执行变速控制,其中根据条件积极地利用发动机制动,有助于多样化的变速控制。
